[0061] FIG. 2 is an exemplary block diagram of an electronic device (e.g., electronic device (101)).

[0062] Referring to FIG. 2, the electronic device (101) may include a processor (120), a pressure sensor (210), an inertial sensor (230), and / or a display (240). The processor (120) may control the overall operations of the electronic device (101). For example, the processor (120) may obtain pre-stored information (e.g., pressure offset data described below) from the pressure sensor (210). For example, the processor (120) may obtain pressure data measured by the pressure sensor (210). For example, the processor (120) may obtain sensing data measured by the inertial sensor (230). The processor (120) may calculate a correction value using the pressure offset data and the sensing data. The processor (120) may correct the pressure data using the calculated correction value. For example, the processor (120) can provide measured pressure data or corrected pressure data to the user through an external output module (e.g., display module (160), audio module (170)).

[0063] The barometric pressure sensor (210) may include a circuit for measuring pressure. The barometric pressure sensor (210) may include a sensing element. The barometric pressure sensor (210) may measure the pressure applied to the sensing element. The barometric pressure sensor (210) may provide pressure data obtained through the measurement to the processor (120). According to one embodiment, the barometric pressure sensor (210) may have a waterproof structure. The barometric pressure sensor (210) may include a waterproof member disposed inside the barometric pressure sensor (210). Due to the waterproof member, the barometric pressure sensor (210) may measure, through the sensing element, the pressure due to the waterproof member in addition to atmospheric pressure. Hereinafter, in the present disclosure, the barometric pressure sensor (210) refers to a component that can measure not only barometric pressure but also pressure due to water pressure or other factors (e.g., a waterproof member described below). The barometric pressure sensor (210) may include a waterproof member. Detailed descriptions of the pressure sensor (210) are described through FIGS. 3a to 3c.

[0064] The inertial sensor (230) may include a circuit for measuring the posture or movement of the electronic device (101). The inertial sensor (230) may be used to measure acceleration and rotation (or inertia) to determine the movement of the electronic device (101) in three dimensions. Sensing data acquired through the inertial sensor (230) may be provided to the electronic device (101) (e.g., the processor (120)). The processor (120) may perform operations according to the movement of the electronic device (101). The inertial sensor (230) may include an acceleration sensor and / or a gyro sensor. For example, the inertial sensor (230) may include a three-axis acceleration sensor. The three-axis acceleration sensor refers to a sensor for detecting movement or inducing a response thereto by measuring acceleration values ​​in each of the x-axis, y-axis, and z-axis. For example, the electronic device (101) can determine whether the electronic device (101) is tilted and / or the tilted angle through sensing data of the inertial sensor (230). For example, the inertial sensor (230) can include a 6-axis gyro acceleration sensor. The gyroscope of the 6-axis gyro acceleration sensor can be configured to measure the degree of rotation with a rotational moment of inertia using the Coriolis effect. The inertial sensor (230) can detect the rotation of the electronic device (101) and / or determine the degree of rotation. For example, when the electronic device (101) is a wearable device such as a wristwatch, the inertial sensor (230) can measure the degree of rotation of the wrist. As another example, when the electronic device (101) is a wearable device such as augmented reality (AR) glasses, the inertial sensor (230) can measure the degree of rotation of the user's head. Hereinafter, examples are described in which the inertial sensor (230) calculates acceleration in each axis and measures rotation angles for each axis, but these examples are not to be construed as limiting other embodiments of the present disclosure.It may also be understood as an embodiment of the present disclosure that the functions of the inertial sensor (230) are performed by dividing them into two separate sensors (e.g., an acceleration sensor and a gyro sensor).

[0065] The display (240) (e.g., display module (160)) can visually provide information (e.g., pressure information) to an external source (e.g., a user) of the electronic device (101). For example, the display (240) can provide pressure information according to the current location (e.g., altitude, direction) of the electronic device (101) to the user. Although the display (240) is illustrated as an output module of the electronic device (101) for providing pressure information to the user in FIG. 2 , embodiments of the present disclosure are not limited thereto. According to one embodiment, the electronic device (101) may not include the display (240). For example, the electronic device (101) can transmit the measured and / or corrected pressure value to the user through another output module (e.g., an audio module (170) for sound, a haptic module (179) for touch). Additionally, for example, the electronic device (101) can provide measured and / or corrected pressure values ​​to another device (e.g., electronic device (102), electronic device (104), server (108)) via a communication module (190).

[0066] Figures 3a to 3c illustrate examples of a pressure sensor (e.g., a pressure sensor (210)). Figures 3a to 3c illustrate examples of a pressure sensor including a waterproof member. The pressure sensor may be placed on a printed circuit board (PCB) and / or a flexible PCB (FPCB) and electrically connected to a processor (e.g., a processor (120)) of an electronic device (101).

[0067] Referring to FIG. 3A, the barometric pressure sensor (210) may include a sensing element (310), a calculation circuit (320), a waterproof member (330), a substrate (340), an adhesive member (350), and / or a housing (360). A sensor package may be placed on the substrate (340). For example, the calculation circuit (320) may be placed on the substrate (340). The calculation circuit (320) may be connected to the sensing element (310) via the adhesive member (350). The housing (360) represents a tube for accommodating the sensing element (310), the calculation circuit (320), the waterproof member (330), and the adhesive member (350). The housing (360) may include an inlet portion used as a passage for a medium (e.g., water, air) for pressure measurement of the barometric pressure sensor (210).

[0068] The sensing element (310) may have a pressure-sensitive surface. For example, the sensing element (310) may include a micro electro mechanical systems (MEMS) sensor. The pressure sensor (210) may measure the pressure applied to the pressure-sensitive surface of the sensing element (310). The membrane of the pressure-sensitive surface may bend as pressure is applied. Depending on the degree to which the membrane of the pressure-sensitive surface bends, the resistance or capacitance changes. The sensing element (310) may measure the pressure by utilizing the degree to which the resistance or capacitance changes.

[0069] The operation circuit (320) can obtain the measurement result (hereinafter, pressure data) of the sensing element (310) from the sensing element (310). The operation circuit (320) can provide an output signal corresponding to the pressure data to the processor (120). For example, the operation circuit (320) can include an application specific integrated circuit (ASIC). According to one embodiment, the operation circuit (320) can store data through an internal storage space (e.g., memory). For example, the operation circuit (320) can store pre-data required for correcting pressure data according to the attitude of the electronic device (101). As an example, the operation circuit (320) can store pressure offset data according to the attitude of the electronic device (101). As an example, the operation circuit (320) can store internal arrangement parameters (e.g., an angular difference between the arrangement of the pressure sensor (210) and the arrangement of the inertial sensor (230).

[0070] The barometric pressure sensor (210) may have a waterproof structure. The barometric pressure sensor (210) may include a waterproof member (330). The waterproof member (330) may be used to protect the sensing element (310) and the calculation circuit (320). The waterproof member (330) may be arranged to cover the sensing element (310) and the calculation circuit (320) within the barometric pressure sensor (210). For example, the waterproof member may include a gel. The gel is relatively fluid compared to a solid. The gel may be applied to protect internal components vulnerable to moisture or humidity, such as the sensing element (310) (e.g., MEMS) and the calculation circuit (320) (e.g., ASIC). The weight of the waterproof member (330) may act as pressure on the sensing element (310) due to gravity. The barometric pressure sensor (210) can measure pressure data that takes into account both the pressure applied to the sensing element (310) through the medium (e.g., air, water) and the pressure applied to the sensing element (310) through the waterproof member (330). Depending on the direction of the barometric pressure sensor (210) (e.g., the direction in which the pressure-sensitive surface of the sensing element (310) faces), the pressure that the waterproof member (330) applies to the sensing element (310) may change due to the influence of gravity. If the pressure due to the waterproof member (330) is not compensated for each time the direction of the barometric pressure sensor (210) changes, an error may occur in the pressure data in the electronic device (101) and the height information (e.g., altitude, water depth) between the electronic device (101). For example, an error of about 0.1 to 0.2 hPa may indicate an altitude difference of about 80 cm to 160 cm. Such errors may cause malfunction of the electronic device (101) in situations requiring precise altitude (e.g., ball games, fitness, Pilates). Therefore, the electronic device (101) according to embodiments of the present disclosure may be configured to calculate the degree of pressure distortion according to the direction of the pressure sensor (210) and compensate for the pressure data of the pressure sensor (210) in order to reduce the influence caused by the waterproof member (330).

[0071] Referring to FIG. 3B, the pressure according to the posture of the electronic device (101) positioned on the ground is illustrated. The electronic device (101) may include an atmospheric pressure sensor (210). For example, in the first posture (371), the direction information of the atmospheric pressure sensor (210) may indicate that the pressure-sensitive surface of the sensing element (310) is about 0 degrees different from the ground. In other words, the direction in which the pressure-sensitive surface faces and the direction in which the ground faces may be substantially the same. Since the atmospheric pressure acts from the outside of the atmospheric pressure sensor (210) to the inside of the atmospheric pressure sensor (210), the atmospheric pressure may act in a direction toward the ground (e.g., in the (-) z-axis direction) through the inlet portion of the housing (360). The pressure applied by the weight of the waterproof member (330) to the sensing element (310) due to gravity may also act in a direction toward the ground (e.g., in the (-) z-axis direction). For example, since the pressure due to the waterproof member (330) and the atmospheric pressure are in substantially the same direction, the pressure measured by the pressure sensor (210) may be measured higher than the atmospheric pressure according to the actual altitude.

[0072] For example, in the second posture (372), the direction information of the pressure sensor (210) may indicate that the pressure-sensitive surface of the sensing element (310) is about 90 degrees apart from the ground. In other words, the difference between the direction in which the pressure-sensitive surface faces and the direction in which the ground faces may be about 90 degrees. Since the atmospheric pressure acts from the outside of the pressure sensor (210) to the inside of the pressure sensor (210), through the inlet portion of the housing (360), the atmospheric pressure may act from the outside in a direction toward the pressure-sensitive surface of the sensing element (310) of the pressure sensor (210) (e.g., the (-) y-axis direction). The direction of gravity and the direction in which the pressure-sensitive surface of the sensing element (310) faces may be substantially perpendicular. Therefore, the pressure applied to the pressure-sensitive surface of the sensing element (310) due to the waterproof member (330) may be less than the corresponding pressure in other positions (e.g., first position (371), third position (373)).

[0073] For example, in the third posture (373), the direction information of the pressure sensor (210) may indicate that the pressure-sensitive surface of the sensing element (310) is about 180 degrees apart from the ground. In other words, the difference between the direction in which the pressure-sensitive surface faces and the direction in which the ground faces may be about 180 degrees. Since the atmospheric pressure acts from the outside of the pressure sensor (210) to the inside of the pressure sensor (210), through the inlet portion of the housing (360), the atmospheric pressure may act from the outside in a direction toward the pressure-sensitive surface of the sensing element (310) of the pressure sensor (210) (e.g., in the (+) z-axis direction). Gravity may act in a direction opposite to the pressure-sensitive surface of the sensing element (310). Depending on gravity, the weight of the waterproof member (330) may at least partially offset the atmospheric pressure applied to the sensing element (310). For example, since the direction of pressure due to the waterproof member (330) and the direction of atmospheric pressure are substantially opposite to each other, the pressure measured by the pressure sensor (210) may be measured to be lower than the atmospheric pressure according to the actual altitude.

[0074] Referring to FIG. 3C, the pressure according to the posture of the electronic device (101) located under the water surface is illustrated. The electronic device (101) may include a pressure sensor (210). The pressure sensor (210) may be used to measure the water pressure according to the water depth under the water surface. For example, in the first posture (381), the direction information of the pressure sensor (210) may indicate that the direction in which the pressure-sensitive surface of the sensing element (310) faces and the direction of gravity differ by about 0 degrees. In other words, the direction of the water pressure under the water surface may be substantially the same as the direction in which the pressure-sensitive surface faces. Since the water pressure acts from the outside of the pressure sensor (210) to the inside of the pressure sensor (210), the water pressure may act in a direction toward the ground (e.g., the (-) z-axis direction) through the inlet portion of the housing (360). Depending on gravity, the pressure exerted by the weight of the waterproof member (330) on the sensing element (310) may also act in the direction of gravity (e.g., in the (-) z-axis direction). For example, since the pressure caused by the waterproof member (330) and the water pressure are in substantially the same direction, the pressure measured by the air pressure sensor (201) may be measured to be higher than the pressure according to the actual water depth.

[0075] For example, in the second posture (382), the direction information of the pressure sensor (210) may indicate that the direction in which the pressure-sensitive surface of the sensing element (310) faces is about 90 degrees different from the direction of gravity. In other words, the difference in the direction of the water pressure under the water surface and the direction in which the pressure-sensitive surface faces may be about 90 degrees. Since the water pressure acts from the outside of the pressure sensor (210) to the inside of the pressure sensor (210), the water pressure may act from the outside through the inlet portion of the housing (360) in a direction (e.g., in the (-) y-axis direction) toward the pressure-sensitive surface of the sensing element (310). The direction of gravity and the direction in which the pressure-sensitive surface of the sensing element (310) faces may be substantially perpendicular. Therefore, the pressure applied to the pressure-sensitive surface of the sensing element (310) due to the waterproof member (330) may be less than the corresponding pressure in other positions (e.g., first position (381), third position (383)).

[0076] For example, in the third posture (383), the direction information of the pressure sensor (210) may indicate that the direction in which the pressure-sensitive surface of the sensing element (310) faces and the direction of gravity differ by about 180 degrees. In other words, the direction of the water pressure under the water surface may be opposite to the direction in which the pressure-sensitive surface faces. Since the water pressure acts from the outside of the pressure sensor (210) to the inside of the pressure sensor (210), through the inlet portion of the housing (360), the water pressure may act in a direction (e.g., the (+) z-axis direction) from the outside toward the pressure-sensitive surface of the sensing element (310) of the pressure sensor (210). Gravity may act in a direction opposite to the pressure-sensitive surface of the sensing element (310). Depending on the gravity, the weight of the waterproof member (330) may at least partially offset the water pressure applied to the sensing element (310). For example, since the direction of pressure due to the waterproof member (330) is substantially opposite to the direction of water pressure, the pressure measured by the barometric pressure sensor (210) may be measured lower than the atmospheric pressure according to the actual water depth.

[0077] Fig. 4 illustrates an operation flow of an electronic device (e.g., electronic device (101)) for correcting pressure data using a pressure offset. As described through Figs. 3a to 3c, since the influence of the waterproof member (330) on the pressure-sensitive surface differs depending on the direction information of the pressure sensor (210) (e.g., the direction of the pressure-sensitive surface of the sensing element (310), the electronic device (101) can correct the pressure data of the pressure sensor (210) depending on the direction information of the pressure sensor (210).

[0078] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0079] Referring to FIG. 4, in operation (401), according to one embodiment, the electronic device (101) (e.g., processor (120)) may determine direction information of the pressure sensor (210). The electronic device (101) may obtain sensing data using the inertial sensor (230). The electronic device (101) may determine direction information of the inertial sensor (230) using the sensing data. The direction information may indicate the direction of a surface on which the inertial sensor (230) is placed (e.g., a surface on which the inertial sensor (230) is mounted in an FPCB). The direction information may include a tilting angle (which may be referred to as a tilt of the electronic device (101)) indicating how much the electronic device (101) is tilted. The electronic device (101) can obtain the difference (hereinafter, angular difference) between the direction of the inertial sensor (230) and the direction of the air pressure sensor (210). For example, the angular difference may be stored in advance inside a component (e.g., the air pressure sensor (210)), determined by a preset of the electronic device (101), and / or obtained by an external user input. The electronic device (101) can determine the direction information of the air pressure sensor (210) using the angular difference and the direction information of the inertial sensor (230). For example, if the inertial sensor (230) and the air pressure sensor (210) are facing substantially the same direction, the angular difference is approximately 0 degrees, and therefore, the electronic device (101) can determine the direction information obtained through the inertial sensor (230) as the direction information of the air pressure sensor (210). For another example, if the inertial sensor (230) and the barometric pressure sensor (210) face opposite directions, the angular difference is approximately 180 degrees, so the electronic device (101) can determine the direction of the barometric pressure sensor (210) as the opposite direction of the direction information obtained through the inertial sensor (230). The direction information of the barometric pressure sensor (210) can indicate how much the pressure-sensitive surface of the sensing element (310) of the barometric pressure sensor (210) is tilted relative to the ground.That is, the above direction information can indicate the difference between the direction in which the pressure-sensitive surface is facing and the direction of gravity.

[0080] In operation (403), according to one embodiment, the electronic device (101) (e.g., the processor (120)) may determine a correction value according to the direction information of the pressure sensor (210) based on the pressure offset data. The electronic device (101) may obtain the pressure offset data. The pressure offset data represents the difference between the pressure value of the sensing element (310) when the waterproof member (330) is not present and the pressure value of the sensing element (310) when the waterproof member (330) is present. Since the influence of the pressure due to the waterproof member (330) differs depending on the direction in which the pressure sensor (210) is placed, the electronic device (101) may obtain the pressure offset data for the sensing element (310) in each of the specified directions of the pressure sensor (210) (e.g., the direction of the pressure-sensitive surface in the first posture (371), the direction of the pressure-sensitive surface in the second posture (372), and the direction of the pressure-sensitive surface in the third posture (373). For example, the pressure offset data for the sensing element (310) may be stored within the pressure sensor (210). As an example, the processor (120) may obtain the pressure offset data from the memory of the ASIC of the pressure sensor (210).

[0081] The electronic device (101) can determine an operation method for pressure compensation using the pressure offset data. The operation method can indicate a compensation value for each direction of the pressure sensor (210). For example, the operation method can be a polynomial equation that uses the direction of the pressure sensor (210) as a variable. The electronic device (101) can determine coefficients of the polynomial equation using the pressure offset data. For example, the electronic device (101) can determine coefficients of each term of a quadratic equation for pressure compensation using pressure offset data when the direction of the pressure sensor (210) is about 0 degrees relative to the ground, pressure offset data when the direction of the pressure sensor (210) is about 90 degrees relative to the ground, and pressure offset data when the direction of the pressure sensor (210) is about 180 degrees relative to the ground. The electronic device (101) can determine a compensation value using the direction information of the pressure sensor (210) of operation (401) in the determined operation method. The electronic device (101) can determine a correction value according to the current posture of the electronic device (101). The posture can indicate the degree or state of inclination of the electronic device (101). Depending on the posture of the electronic device (101), the direction information of the pressure sensor (210) of the electronic device (101) (e.g., the direction in which the pressure-sensitive surface is facing) can vary. The electronic device (101) can determine a correction value corresponding to the direction information of the pressure sensor (210) of the operation (401).

[0082] In operation (405), according to one embodiment, the electronic device (101) (e.g., processor (120)) may provide pressure information using the pressure data and correction value of the pressure sensor (210). The electronic device (101) may measure the pressure data of the pressure sensor (210). Since the measured pressure data is a result reflecting not only the atmospheric pressure but also the pressure due to the weight of the waterproof member (330), the electronic device (101) may obtain the pressure (e.g., atmospheric pressure, water pressure) actually applied to the pressure sensor (210) through the correction value. The electronic device (101) may provide the corrected pressure data as pressure information through the pressure data and correction value. For example, the pressure information may be provided to the user of the electronic device (101). For example, the altitude or water depth corresponding to the pressure information may be displayed through the display (240) of the electronic device (101). As another example, if the altitude corresponding to the pressure information is above a threshold value, a separate notification (e.g., vibration) may be provided to the user. As another example, the altitude or depth corresponding to the pressure information may be output as an audio signal through the speaker of the electronic device (101) or a separate device (e.g., wireless earphones). As another example, the pressure information may be provided to another device (e.g., electronic device (102), electronic device (104), server (108)).

At least one of the components of the electronic device (101) described in FIG. 6 may be identical or similar to at least one of the components of the electronic device (101) of FIGS. 1, 2, 5A and / or 5B, and any redundant description will be omitted below. The support member (660) may be disposed inside the electronic device (101) and connected to the side bezel structure (610), or may be formed integrally with the side bezel structure (610). The support member (660) may be formed of, for example, a metallic material and / or a non-metallic (e.g., a polymer) material. The display (520) may be coupled to one surface of the support member (660), and a printed circuit board (680) may be coupled to the other surface of the support member (660).

According to one embodiment, at least one sensor (e.g., a barometric pressure sensor (210), an inertial sensor (230)) may be electrically connected to the processor (120) of the printed circuit board (680). For example, at least one sensor (e.g., barometric pressure sensor (210), inertial sensor (230)) may be placed on a separate substrate (e.g., FPCB) connected to the printed circuit board (680). As another example, at least one sensor (e.g., barometric pressure sensor (210), inertial sensor (230)) may be placed on top of the printed circuit board (680).

[0096] The battery (670) is a device for supplying power to at least one component of the electronic device (101), and may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell. At least a portion of the battery (670) may be disposed substantially on the same plane as, for example, the printed circuit board (680). The battery (670) may be disposed integrally within the electronic device (101), or may be disposed detachably from the electronic device (101).

[0097] The first antenna (650) may be disposed between the display (520) and the support member (660). The first antenna (650) may include, for example, a near field communication (NFC) antenna, a wireless charging antenna, and / or a magnetic secure transmission (MST) antenna. The first antenna (650) may, for example, perform short-range communication with an external device, wirelessly transmit and receive power required for charging, and transmit an electromagnetic signal including a short-range communication signal or payment data. In one embodiment, the antenna structure may be formed by at least a portion of the side bezel structure (610) and / or a portion of the support member (660), or a combination thereof. The second antenna (655) may be disposed between the printed circuit board (680) and the back plate (693). The second antenna (655) may include, for example, a near field communication (NFC) antenna, a wireless charging antenna, and / or a magnetic secure transmission (MST) antenna. The second antenna (655) can, for example, perform short-range communication with an external device, wirelessly transmit and receive power required for charging, and transmit electromagnetic signals containing short-range communication signals or payment data. In one embodiment, the antenna structure may be formed by a portion or combination of the side bezel structure (610) and / or the rear plate (693).

[0098] A sealing member (690) may be positioned between the side bezel structure (610) and the rear plate (693). The sealing member (690) may be configured to block or reduce moisture and foreign substances from entering the space surrounded by the side bezel structure (610) and the rear plate (693) from the outside.

[0099] FIG. 7 illustrates an example of an electronic device (e.g., electronic device (101)) including a pressure sensor (e.g., pressure sensor (210)) and an inertial sensor (e.g., inertial sensor (230)). The arrangement of the pressure sensor (210) and the inertial sensor (230) in FIG. 7 is merely an example of a measurement environment described below and is not to be construed as limiting embodiments of the present disclosure.

[0100] Referring to FIG. 7, the electronic device (101) may include a barometric sensor (210) and an inertial sensor (230). The plan view (701) is a drawing of the electronic device (101) viewed in one direction (e.g., the (-) z-axis direction). The front view (702) is a drawing of the electronic device (101) viewed in another direction (e.g., the (-) x-axis direction). The electronic device (101) may determine a state (e.g., a rotation state, a tilting angle) of the electronic device (101) through the inertial sensor (230). The electronic device (101) may determine direction information of the barometric sensor (210) by using the difference between the arrangement of the inertial sensor (230) and the arrangement of the barometric sensor (210) and the state of the electronic device (101). The direction information of the pressure sensor (210) is determined through the sensing data of the inertial sensor (230). For more accurate correction, for example, the pressure sensor (210) and the inertial sensor (230) may be arranged on the same plane (e.g., xy plane). As described in FIGS. 3A to 3C, the pressure data measured by the pressure sensor (210) may be distorted due to the waterproof member (330). The electronic device (101) may adjust the pressure value distorted due to the waterproof member (330) in the pressure sensor (210) by using the pressure offset data measured and calculated in advance.

[0101] Meanwhile, in FIG. 7, the barometric pressure sensor (210) and the inertial sensor (230) are illustrated as being arranged on the same plane, but the embodiments of the present disclosure are not limited thereto. Even if the plane on which the barometric pressure sensor (210) is arranged and the plane on which the inertial sensor (230) is arranged are different, pressure compensation according to the embodiments of the present disclosure can be utilized by reflecting the angle and height difference between the two sensors.

[0102] FIGS. 8A and 8B illustrate examples of pressure data resulting from a drop of an electronic device (e.g., electronic device (101)).

[0103] Referring to FIG. 8A, a graph (800) represents a change in a pressure value measured in an electronic device (101) when the electronic device (101) is dropped from a certain height from the ground without changing direction. The horizontal axis of the graph (800) represents time (unit: sample index), and the vertical axis of the graph (800) represents pressure (unit: hPa (hectopascal)). As the electronic device (101) falls, the closer the electronic device (101) gets to the ground, the greater the atmospheric pressure experienced by the electronic device (101). For example, at a first point (811), the drop of the electronic device (101) may begin. At a second point (812), the electronic device (101) may touch the ground. Referring to the graph (800), it can be confirmed that the actual atmospheric pressure increases as the altitude of the electronic device (101) decreases. Referring to sample indices from about 60 to about 100 in the graph (800), it can be confirmed that the pressure measured by the electronic device (101) gradually increases.

[0104] Referring to FIG. 8B, a graph (850) represents a change in a pressure value measured in an electronic device (101) when the electronic device (101) changes direction and falls from a certain height from the ground. The horizontal axis of the graph (850) represents time (unit: sample index), and the vertical axis of the graph (850) represents pressure (unit: hPa). As the electronic device (101) falls, the closer the electronic device (101) gets to the ground, the greater the atmospheric pressure received by the electronic device (101). However, as the electronic device (101) is turned over, the direction of the atmospheric pressure sensor (210) of the electronic device (101) may change. For example, as in the third posture (373) of FIG. 3B, the direction in which the pressure-sensitive surface of the sensing element (310) of the atmospheric pressure sensor (210) faces may be opposite to the direction in which the atmospheric pressure faces. For example, at a first point (861), the electronic device (101) may begin to fall. At a second point (862), the electronic device (101) may flip over. At a third point (863), the electronic device (101) may touch the ground. Referring to the graph (850), it can be confirmed that the pressure measured by the electronic device (101) decreases even though the actual atmospheric pressure should increase due to the decrease in the altitude of the electronic device (101).

[0105] Fig. 8c shows an example of the results of pressure measurement. Fig. 8c shows the test results resulting from the dropping of a single component (e.g., pressure sensor (210)) of an electronic device (101).

[0106] Referring to FIG. 8c, a graph (870) represents normalized test pressure values ​​over time. The horizontal axis of the graph (870) represents time (unit: seconds), and the vertical axis of the graph (870) represents normalized test pressure values ​​(unit: hPa). It can be confirmed that the test pressure value increases in a section of about 4 to 5 seconds due to a change in the altitude of the electronic device (101) compared to other time sections. Although the pressure should increase as the altitude decreases, the graph (850) produced a result that was different from the expectation. This is because the graph (850) of FIG. 8b did not reflect the effect of the change in pressure due to the waterproof member (330) due to the change in the orientation of the electronic device (101). The change in the orientation of the electronic device (101) results in the pressure measured by the electronic device (101) being different from the actual atmospheric pressure.

[0107] Figure 8d shows an example of an accuracy shift of a measured pressure according to the degree of rotation of a pressure sensor (e.g., pressure sensor (210)).

[0108] Referring to FIG. 8d, a graph (890) represents a change in accuracy according to a degree of rotation. The horizontal axis of the graph (890) represents a degree of rotation (e.g., roll angle) (unit: degree), and the vertical axis of the graph (890) represents a change in accuracy (unit: hPa). The degree of rotation may represent how much the direction in which the pressure sensor (210) of the electronic device (101) faces has rotated with respect to a reference direction. For example, the reference direction may represent a direction in which the ground faces (i.e., a direction opposite to the direction of gravity). In the first posture (371) of FIG. 3b or the first posture (381) of FIG. 3c, the degree of rotation may be approximately 0 degrees. For example, the electronic device (101) may be a wearable device of the watch type worn on a user's wrist. The electronic device (101) may rotate with the direction from the user's arm to the hand as the rotation axis. The change in accuracy may represent the difference between the actual atmospheric pressure at the given altitude and the pressure measured by the pressure sensor (210). In other words, the change in accuracy may represent a correction value for the measured pressure of the sensing element (310).

[0109] Referring to the graph (890), it can be confirmed that the correction value changes in a certain manner according to the degree of rotation of the electronic device (101). For example, the first line (891) represents the change in accuracy according to the first sample. The first line (891) has a value of about -0.17 at about 180 degrees, a value of about -0.1012 at about 135 degrees, a value of about -0.05 at about 90 degrees, a value of about -0.0162 at about 45 degrees, and a value of about 0 at about 0 degrees. For example, the second line (891) represents the change in accuracy according to the second sample. The second line (892) has a value of about -0.14 at about 180 degrees, a value of about -0.0825 at about 135 degrees, a value of about -0.04 at about 90 degrees, a value of about -0.0125 at about 45 degrees, and a value of about 0 at about 0 degrees. For example, the third line (891) shows the accuracy change according to the third sample. The third line (893) has a value of about -0.18 at about 180 degrees, a value of about -0.15 at about 135 degrees, a value of about -0.077 at about 90 degrees, a value of about -0.025 at about 45 degrees, and a value of about 0 at about 0 degrees. Referring to the first line (8910), the second line (892), and the third line (893), it can be confirmed that the slope of each line changes abruptly at about 90 degrees and / or about -90 degrees. The above-described method can be used for modeling. For example, in modeling according to the samples of the graph (890), in addition to about 0 degrees and about 180 degrees, measurement data (e.g., pressure offset data) at about 90 degrees can be significantly used for pressure compensation described below. The electronic device (101) can determine an operation method that defines the relationship between the direction information of the pressure sensor (210) and the compensation value based on statistical results according to the degree of rotation and the change in accuracy. As an example, the operation method can be a polynomial function.

[0110] Fig. 9a illustrates an operation flow of a device for measuring pressure offset data of a barometric pressure sensor. Fig. 9b illustrates an example of a test board (910) for the pressure offset data. The device may be an electronic device (101), a device including the electronic device (101), or a separate test device (e.g., the test board (910) of Fig. 9b). The test board (910) illustrated in Fig. 9b may include a substrate (911), a processor (920), a barometric pressure sensor (210), an inertial sensor (230), and a non-waterproof barometric pressure sensor (940). The barometric pressure sensor (210) and the inertial sensor (230) may be the same as the barometric pressure sensor (210) and the inertial sensor (230) included in the electronic device (101) for testing. The processor (920) may be configured to process data from the barometric pressure sensor (210), the inertial sensor (230), and the non-waterproof barometric pressure sensor (940), and perform operations using the data. For example, the processor (920) may perform specified operations or store related values ​​in another component (e.g., the barometric pressure sensor (210)) using pressure data measured by the barometric pressure sensor (210), sensing data (e.g., position, attitude, inclination) measured by the inertial sensor (230), and / or pressure data measured by the non-waterproof barometric pressure sensor (940). The non-waterproof barometric pressure sensor (940) refers to a barometric pressure sensor that does not have a waterproof member (330) unlike the barometric pressure sensor (210). For example, the sensing element of the non-waterproof barometric pressure sensor (940) may be in direct contact with a medium (e.g., air). The pressure measured by the non-waterproof pressure sensor (940) can be used as a reference pressure for the pressure sensor (210). The test board (910) can be used to obtain changes in the accuracy of the measured pressure according to the degree of rotation (e.g., rotation angle) of the pressure sensor (210). In order to more accurately measure the atmospheric pressure (or water pressure) through the pressure sensor (210), it may be required to eliminate the influence caused by the waterproof member (330) inside the pressure sensor (210).Accordingly, the processor (920) of the test board (910) can calculate the pressure offset data for each direction of the pressure sensor (210). For example, the processor (920) can calculate the pressure offset data in a specified direction based on the difference between the pressure measured by the non-waterproof pressure sensor (940) and the pressure measured by the pressure sensor (210). Since the waterproof member (330) is not arranged inside the non-waterproof pressure sensor (940), the pressure difference according to the direction of the non-waterproof pressure sensor (940) may be relatively less than that of the pressure sensor (210). According to one embodiment, the pressure data measured by the non-waterproof pressure sensor (940) may be used as a reference pressure for determining the pressure offset due to the weight of the waterproof member (330). For example, the difference between the pressure value of the non-waterproof pressure sensor (940) and the pressure value of the waterproof pressure sensor (210) may indicate the error level of the pressure value of the pressure sensor (210) according to the angle.

[0111] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0112] Referring to FIG. 9A, according to one embodiment, in operation (901), the device (e.g., the processor (920)) may set an acceleration target value of the inertial sensor (230) according to the direction of the pressure sensor (210). The direction of the pressure sensor (210) indicates the direction of the sensing element (310) of the pressure sensor (210) (e.g., the direction in which the pressure-sensitive surface of the sensing element (310) is facing). The acceleration target value may indicate the influence of gravity due to the weight of the waterproof member (330). For example, the device may set the acceleration target value of the inertial sensor (230) in each of three states in which the angle between the pressure-sensitive surface and the ground is about 0 degrees, about 90 degrees, and about 180 degrees. In the first state in which the angle between the pressure-sensitive surface and the ground is about 0 degrees, the magnitude of gravity due to the weight of the waterproof member (330) may be about 1 G. In a second state where the angle between the pressure-sensing surface and the ground is approximately 90 degrees, the magnitude of the gravity due to the weight of the waterproof member (330) may be approximately 0 G. In a third state where the angle between the pressure-sensing surface and the ground is approximately 180 degrees, the magnitude of the gravity due to the weight of the waterproof member (330) may be approximately -1 G.

[0113] According to one embodiment, in operation (903), the device (e.g., processor (920)) can measure pressure according to an acceleration target value. The device can determine whether the acceleration of the sensing data of the inertial sensor (230) reaches the acceleration target value. When the acceleration indicated by the sensing data of the inertial sensor (230) reaches the acceleration target value, the device can measure the pressure through each of the barometric pressure sensor (210) and the non-waterproof barometric pressure sensor (940). For example, in the first state, when the sensing data of the inertial sensor (230) indicates about 1 G, the device can measure the pressure through each of the barometric pressure sensor (210) and the non-waterproof barometric pressure sensor (940). For example, in the second state, the device can measure pressure through each of the barometric pressure sensor (210) and the non-waterproof barometric pressure sensor (940) when the sensing data of the inertial sensor (230) indicates about 0G. For example, in the third state, the device can measure pressure through each of the barometric pressure sensor (210) and the non-waterproof barometric pressure sensor (940) when the sensing data of the inertial sensor (230) indicates about -1G.

[0114] According to one embodiment, in operation (905), the device (e.g., processor (920)) can calculate a difference between a pressure measured by a pressure sensor (e.g., pressure sensor (210)) and a reference pressure. The reference pressure can be set in various ways. For example, the reference pressure can be set to a preset value (e.g., 1013 hPa). As another example, the reference pressure can be data measured by a non-waterproof pressure sensor (940). Based on a specific state, the device can determine the difference between the pressure measured by the pressure sensor (210) and the reference pressure as pressure offset data in the specific state. For example, the device can determine the difference between the pressure measured by the pressure sensor (210) in the first state and the reference pressure as pressure offset data with respect to a first direction of the pressure sensor (210) (e.g., the direction of the pressure-sensitive surface of the pressure sensor (210), which protrudes vertically from the ground). For example, the device can determine the difference between the pressure measured by the pressure sensor (210) in the second state and the reference pressure as pressure offset data for the second direction of the pressure sensor (210) (e.g., the direction of the pressure-sensitive surface of the pressure sensor (210), the direction parallel to the ground). For example, the device can determine the difference between the pressure measured by the pressure sensor (210) in the third state and the reference pressure as pressure offset data for the third direction of the pressure sensor (210) (e.g., the direction of the pressure-sensitive surface of the pressure sensor (210), the direction toward the ground).

[0115] According to one embodiment, in operation (907), the device (e.g., processor (920)) may store pressure offset data. The device may store the pressure offset data in the waterproof pressure sensor (210). For example, the pressure offset data for each direction of the pressure sensor (210) may be stored in the memory space within the ASIC of the pressure sensor (210). Thereafter, the waterproof pressure sensor (210) may be mounted on a substrate (e.g., FPCB) of the electronic device (101) and used for pressure compensation as described in FIG. 4.

[0116] Referring back to FIG. 9B, the test board (910) can be used to measure changes in pressure values ​​according to the rotation of the barometric pressure sensor (210). For example, in an environment where changes in barometric pressure due to external wind or air flow are minimized, pressure offset data can be measured through data of the barometric pressure sensor (210) and / or the non-waterproof barometric pressure sensor (940) when the test board (910) rotates. According to one embodiment, the processor (920) can store correction values ​​for the barometric pressure sensor (210) at each of the specified angles (e.g., approximately 0 degrees (e.g., corresponding to 1 G), approximately 90 degrees (e.g., corresponding to 0 G), 180 degrees (e.g., corresponding to -1 G)) during rotation in the memory of the electronic device (101) (e.g., the memory of the barometric pressure sensor (210)). The specified directions may be used relatively frequently compared to other directions when the user wears the electronic device (101). The above-described angles are described in more detail with reference to FIGS. 10A to 10C. Referring to the arrangement of FIG. 9B, the barometric pressure sensor (210) and the inertial sensor (930) within the test board (910) may be arranged based on the arrangement within the electronic device (101). For example, the barometric pressure sensor (210) and the inertial sensor (930) may be arranged according to the position where each component is mounted within the electronic device (101), as in the plan view (701) of FIG. 7. Since the waterproofing member (330) within the barometric pressure sensor (210) is not uniformly applied in all directions, it is required to compensate for the pressure in a direction that provides high usability for the user. Therefore, the barometric pressure sensor (210) and the inertial sensor (230) may be arranged within the test board (910) taking into account the arrangement within the electronic device (101).

[0117] In FIGS. 9A and 9B , a test board (910) is described as an example as a device for measuring pressure offset data, but embodiments of the present disclosure are not limited thereto. For example, an electronic device (101) that uses a preset value (e.g., a value pre-input through measurement by a separate device) instead of a non-waterproof pressure sensor (940) as a reference pressure may be used to measure the pressure offset data. For another example, unlike FIGS. 9A and 9B , an electronic device (101) including a non-waterproof pressure sensor (940) may be used to measure the pressure offset data.

[0118] Figures 10a, 10b, and 10c illustrate examples of measurement environments for pressure offset data. When external environmental variables are ideally controlled and assumed to be uniform, the barometric pressure sensor (210) can be subjected to the same atmospheric pressure regardless of its orientation. In other words, if external forces are excluded and only atmospheric pressure is measured by the barometric pressure sensor (210), the barometric pressure sensor (210) should output the same pressure data regardless of orientation. However, the waterproof member (330) inside the barometric pressure sensor (210) may cause unexpected errors.

[0119] Referring to FIG. 10A, pressure offset data can be measured for three directions. The pressure offset data can include first pressure offset data, second pressure offset data, and third pressure offset data. For example, when a first state (1001) of the electronic device (101) is assumed (e.g., a state in which the display (e.g., the display 520) of the electronic device (101) faces in an opposite direction to the ground), the first pressure offset data can be measured. The direction information of the pressure sensor (210) can indicate that the pressure-sensitive surface of the sensing element (310) faces the (+) z-axis direction. For example, since the barrel of the housing (360) of the pressure sensor (210) faces the display (e.g., the display 520) of the electronic device (101), the direction information of the pressure sensor (210) can indicate that the pressure-sensitive surface faces the (+) z-axis direction. The angle formed by the pressure-sensitive surface and the ground can be approximately 0 degrees. The direction in which the inlet portion of the housing of the pressure sensor (210) faces may be approximately 90 degrees relative to the ground. The gravity due to the waterproof member (330) may correspond to 1 G. For example, when the second state (1002) of the electronic device (101) is assumed (e.g., a state in which the display (e.g., the display (520)) of the electronic device (101) faces in a direction substantially perpendicular to the ground), the second pressure offset data may be measured. The direction information of the pressure sensor (210) may indicate that the pressure-sensitive surface of the sensing element (310) faces the (-) y-axis direction. The angle formed by the pressure-sensitive surface and the ground may be approximately 90 degrees. The direction in which the inlet portion of the housing of the pressure sensor (210) faces may be substantially parallel to the ground (i.e., approximately 0 degrees). The gravity due to the waterproof member (330) may correspond to 0 G. For example, when a third state (1003) of the electronic device (101) is assumed (e.g., a state in which the display (e.g., display (520)) of the electronic device (101) is facing the ground), third pressure offset data can be measured.The direction information of the pressure sensor (210) may indicate that the pressure-sensitive surface of the sensing element (310) faces the (-) z-axis direction. The angle formed between the pressure-sensitive surface and the ground may be approximately 180 degrees. The inlet portion of the housing of the pressure sensor (210) may face the ground. The gravity due to the waterproof member (330) may correspond to -1 G.

[0120] Depending on the direction of the pressure sensor (210), a difference in the influence of gravity on the waterproof member (330) within the pressure sensor (210) may cause inaccurate height (altitude or depth) calculations. Therefore, in each of the first state (1001), the second state (1002), and the third state (1003), pressure offset data, which is the difference between the reference pressure and the measured pressure, may be calculated in advance. The calculated pressure offset data may be stored within the electronic device (101). For example, the calculated pressure offset data may be stored within the pressure sensor (210) (e.g., in an ASIC).

[0121] Referring to FIG. 10b, the graph (1030) represents pressure data for each state. The horizontal axis of the graph (1030) represents a measurement section, and a different gravitational acceleration (unit: G (gravity)) to the waterproof member (330) may be applied to each measurement section. For example, in the first measurement section (1041), the gravity due to the waterproof member (330) may correspond to approximately 0 G. In the second measurement section (1042), the gravity due to the waterproof member (330) may correspond to approximately -1 G. In the third measurement section (1043), the gravity due to the waterproof member (330) may correspond to approximately 1 G. The vertical axis of the graph (1030) represents pressure data. Line (1031) represents pressure data measured through a pressure sensor (210), and line (1032) represents pressure data measured through a non-waterproof pressure sensor (e.g., non-waterproof pressure sensor (940)). For example, in the first measurement section (1041), pressure data (y2) represents pressure data measured when the gravity due to the waterproof member (330) is about 0G. In the second measurement section (1042), pressure data (y1) represents pressure data measured when the gravity due to the waterproof member (330) is about -1G. In the third measurement section (1043), pressure data (y3) represents pressure data measured when the gravity due to the waterproof member (330) is about 1G. A device for measuring pressure offset data (e.g., electronic device (101), test board (910)) can repeatedly acquire pressure data when the acceleration value of the inertial sensor (230) reaches a target value. For example, the device can acquire 100 pressure data from each of the pressure sensor (210) and the non-waterproof pressure sensor (940) in each state.

[0122] The device can obtain 100 pressure data of each of the barometric pressure sensor (210) and the non-waterproof barometric pressure sensor (940) in a first state (1001). The device can determine first measured pressure data from the 100 pressure data of the barometric pressure sensor (210). For example, the first measured pressure data may be an average value, a median value, or a filtered value of the 100 pressure data. As a non-limiting example, the filtered value may represent an average of remaining data after excluding unnecessary data from the pressure data in the first state (1001). In the same manner, the device can determine first reference pressure data from the 100 pressure data of the non-waterproof barometric pressure sensor (940). The device can determine first pressure offset data in the first state (1001) based on a difference between the first measured pressure data and the first reference pressure data.

[0123] The device can obtain 100 pressure data of each of the barometric pressure sensor (210) and the non-waterproof barometric pressure sensor (940) in the second state (1002). The device can determine second measured pressure data from the 100 pressure data of the barometric pressure sensor (210). For example, the second measured pressure data may be an average value, a median value, or a filtered value of the 100 pressure data. As a non-limiting example, the filtered value may represent an average of remaining data after excluding unnecessary data from the pressure data in the second state (1002). In the same manner, the device can determine second reference pressure data from the 100 pressure data of the non-waterproof barometric pressure sensor (940). The device can determine second pressure offset data in the second state (1002) based on a difference between the second measured pressure data and the second reference pressure data.

[0124] The device can obtain 100 pressure data of each of the barometric pressure sensor (210) and the non-waterproof barometric pressure sensor (940) in the third state (1003). The device can determine third measured pressure data from the 100 pressure data of the barometric pressure sensor (210). For example, the third measured pressure data may be an average value, a median value, or a filtered value of the 100 pressure data. As a non-limiting example, the filtered value may represent an average of remaining data obtained by excluding unnecessary data from the pressure data in the third state (1003). In the same manner, the device can determine third reference pressure data from the 100 pressure data of the non-waterproof barometric pressure sensor (940). The device can determine third pressure offset data in the third state (1003) based on a difference between the third measured pressure data and the third reference pressure data.

[0125] The device may store the first pressure offset data, the second pressure offset data, and / or the third pressure offset data inside the electronic device (101) (e.g., in the internal memory of the pressure sensor (210). According to one embodiment, each pressure offset data may represent a difference between measured pressure data and reference pressure data. The device may store pressure offset data in each of the three directions. For example, the electronic device (101) may perform pressure compensation using the values ​​stored in the pressure sensor (210) in each of the first state (1001), the second state (1002), and the third state (1003). The electronic device (101) may calculate a correction value through an operation method determined based on the value stored as the first pressure offset data, the base value, the value stored as the second pressure offset data, and the value stored as the third pressure offset data in different states (e.g., when the electronic device (101) is in a different posture from the first state (1001), the second state (1002), and the third state (1003). For the operation method, reference may be made to the description of FIG. 4. As an example, each pressure offset data may be determined according to the following mathematical equation.

[0126]

[0127] The above mathematical formula 1 is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical formula 1 may be modified, applied, or expanded in various ways.

[0128] P_offset_1 represents the first pressure offset data, P[0] represents the first measured pressure data, and RP[0] represents the first reference pressure data. C represents a constant for securing the number of bits during internal storage, and as a non-limiting example, C may be -10.

[0129]

[0135] In another embodiment, instead of storing all the pressure offset data in each of the three directions, the device may store two sets of pressure offset data. For example, in the first state (1001), the direction information of the pressure sensor (210) may be set to the reference direction. The first pressure offset data may be set to a default value (e.g., 0). In other words, the pressure compensation value due to the waterproof member in the first state (1001) may be set to a default value (e.g., 0). For example, since the height change is relative, the device may determine the second pressure offset data as a value obtained by subtracting the 'difference between the second measured pressure data and the second reference pressure data' from the 'difference between the first measured pressure data and the first reference pressure data'. For example, the device may determine the third pressure offset data as a value obtained by subtracting the 'difference between the third measured pressure data and the third reference pressure data' from the 'difference between the first measured pressure data and the first reference pressure data'. For example, the electronic device (101) may perform pressure compensation using a base value in a first state (1001), and may perform pressure compensation using a value stored in the pressure sensor (210) in each of the second state (1002) and the third state (1003). In other states (e.g., the electronic device (101) is in a different posture from the first state (1001), the second state (1002), and the third state (1003), the electronic device (101) may calculate a compensation value through an operation method determined according to the base value, the value stored as the second pressure offset data, and the value stored as the third pressure offset data. For the operation method, reference may be made to the description of FIG. 4.

[0136] For example, each pressure offset data can be determined according to the following mathematical formula.

[0137]

[0138] The above mathematical equation (4) is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical equation (4) may be modified, applied, or expanded in various ways.

[0139] P_offset_1 represents the first pressure offset data.

[0140]

[0141] The above mathematical equation (5) is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical equation (5) may be modified, applied, or expanded in various ways.

[0142] P_offset_2 represents the second pressure offset data, P[0] represents the first measured pressure data, and RP[0] represents the first reference pressure data. P[1] represents the second measured pressure data, and RP[1] represents the second reference pressure data. C represents a constant for securing the number of bits during internal storage, and as a non-limiting example, C may be -10.

[0143]

[0144] The above mathematical equation (6) is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical equation (6) may be modified, applied, or expanded in various ways.

[0145] P_offset_3 represents the third pressure offset data, P[0] represents the first measured pressure data, and RP[0] represents the first reference pressure data. P[2] represents the third measured pressure data, and RP[2] represents the third reference pressure data. C represents a constant for securing the number of bits during internal storage, and as a non-limiting example, C may be -10.

[0146] In FIG. 10b, the direction of the pressure sensor (210) in the first state (1001) is described as the reference direction, but embodiments of the present disclosure are not limited thereto. The direction corresponding to -1G may also be set as the reference direction. In this case, the third pressure offset data is set to a reference value (e.g., 0), and the electronic device (101) can obtain only the first pressure offset data and the second pressure offset data from the pressure sensor (210) to perform pressure compensation.

[0147] Referring to FIG. 10c, the rotation direction of the electronic device (101) can be determined based on the user's frequency of use. In the process of measuring the pressure offset, the rotation direction is important during rotation. For example, the electronic device (101) may be a watch-type wearable device. The first wearing example (1060) shows that the electronic device (101) is worn on the user's left wrist. The user can rotate the electronic device (101) in a direction with a high degree of freedom. In the first wearing example (1060), when the direction of the hand on the user's arm is the central axis, the electronic device (101) can rotate in a counterclockwise direction (1081). The second wearing example (1070) shows that the electronic device (101) is worn on the user's right wrist. The user can rotate the electronic device (101) in a direction with a high degree of freedom. In the second wearing example (1070), when the direction of the hand on the user's arm is taken as the central axis, the electronic device (101) can rotate in a clockwise direction (1082). Although there is a difference between the counterclockwise direction (1081) and the clockwise direction (1082) from the user's perspective, it can be understood that the rotation is substantially in the same direction from the electronic device (9101). For example, since the user generally turns the watch more outward from the user due to the body structure, the rotation range can correspond to 0 degrees to 180 degrees in one direction of the electronic device (101) (e.g., the (-) x-axis direction based on FIG. 7). As an example, the 0 degree may indicate a direction in which the display of the electronic device (101) is parallel to the ground.

[0148] Fig. 11 illustrates an operation flow of an electronic device (e.g., an electronic device (101)) for determining direction information of a pressure sensor (e.g., a pressure sensor (210)). The operations of Fig. 11 may correspond to the operation of determining direction information of the pressure sensor (210) in operation (401) of Fig. 4.

[0149] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0150] Referring to FIG. 11, according to one embodiment, in operation (1101), the electronic device (101) (e.g., the processor (120)) may obtain sensing data from an inertial sensor (e.g., the inertial sensor (230)). For example, the sensing data may include acceleration values ​​measured by the inertial sensor (230). For example, the sensing data may include an acceleration value about the x-axis, an acceleration value about the y-axis, and / or an acceleration value about the z-axis. For example, the sensing data may include rotation angles measured by the inertial sensor (230). For example, the sensing data may include a roll value, a pitch value, and / or a yaw value. The roll value may represent a rotation angle about a rotation axis of the electronic device (101). The roll value may represent a rotation angle of the inertial sensor (230) and / or the air pressure sensor (210).

[0151] According to one embodiment, in operation (1103), the electronic device (101) (e.g., the processor (120)) may determine direction information of the inertial sensor (230) using the sensing data. For example, the electronic device (101) may determine direction information of the inertial sensor (230) through acceleration values ​​for each axis of the sensing data. For example, the electronic device (101) may determine direction information of the inertial sensor (230) using rotation angles of the sensing data. As a non-limiting example, the electronic device (101) may perform filtering by considering the difference in output data rate (ODR) between the inertial sensor (230) and the barometric pressure sensor (210). The filtering may be used to prevent a situation in which the degree of error increases due to a sudden change. Operations by which the electronic device (101) determines direction information of the inertial sensor (230) are described in detail through FIG. 13.

[0152] According to one embodiment, in operation (1105), the electronic device (101) (e.g., processor (120)) may obtain an angular difference between the inertial sensor (230) and the pressure sensor (210). For example, the angular difference between the inertial sensor (230) and the pressure sensor (210) may represent an angular difference between a surface on which the inertial sensor (230) is mounted and a surface on which the pressure sensor (210) is mounted. For example, the inertial sensor (230) may be disposed on one surface of a substrate (e.g., FPCB). The pressure sensor (210) may be disposed on one surface of the substrate or on another surface of the substrate opposite to the one surface. The angular difference may represent an angular difference between a direction in which the surface on which the inertial sensor (230) is mounted faces and a direction in which a pressure-sensitive surface of a sensing element (310) of the pressure sensor (210) faces. For example, if the barometric pressure sensor (210) and the inertial sensor (230) are mounted on the same plane, a total of four examples can be referenced. The four examples are as shown in the table below.

[0153] #1#2#3#4 Orientation information of the barometric sensor (e.g., tilt angle)0°0°180°180° Orientation information of the inertial sensor (e.g., tilt angle)0°180°0°180°Angle difference between the inertial sensor and the barometric sensor0°180°180°0°

[0154] According to one embodiment, the electronic device (101) can obtain the angular difference between the inertial sensor (230) and the barometric pressure sensor (210) from the barometric pressure sensor (210). Before the barometric pressure sensor (210) is mounted on the board of the electronic device (101), information about the angular difference due to the difference in the arrangement of the barometric pressure sensor (210) and the arrangement of the inertial sensor (230) may be stored in advance in the barometric pressure sensor (210). For example, information about the angular difference may be stored in the ASIC of the barometric pressure sensor (210). The electronic device (101) can obtain the angular difference between the inertial sensor (230) and the barometric pressure sensor (210) from the ASIC. According to another embodiment, the electronic device (101) can obtain information about the angular difference between the inertial sensor (230) and the barometric pressure sensor (210) through an external input. Depending on the design layout of the electronic device (101) or a number indicating the design layout, the angular difference between the inertial sensor (230) and the barometric sensor (210) within the electronic device (101) may be provided to the electronic device (101) through a separate input. For example, the electronic device (101) may obtain the angular difference between the inertial sensor (230) and the barometric sensor (210) from a separate device (e.g., the electronic device (102), the electronic device (104), and / or the server (108)) that is connected to the electronic device (101) through wireless communication. As another example, the electronic device (101) may obtain the angular difference between the inertial sensor (230) and the barometric sensor (210) through a manual input from a user of the electronic device (101).

[0155] According to one embodiment, in operation (1107), the electronic device (101) (e.g., the processor (120)) may determine direction information of the pressure sensor (210). The electronic device (101) may determine direction information of the pressure sensor (210) based on the angular difference between the inertial sensor (230) and the pressure sensor (210) and the direction information of the inertial sensor (230).

[0156] The electronic device (101) may determine a correction value according to operation (403) after determining the direction information of the pressure sensor (210). Before determining the correction value, the electronic device (101) may determine an operation method for pressure correction. The operation method for the pressure correction may be independent of the determination of the direction information of the pressure sensor. For example, the operation method for the pressure correction may be determined and stored in advance before the direction information of the pressure sensor. As another example, the operation method for the pressure correction may be derived after determining the direction information of the pressure sensor.

[0157] The electronic device (101) can determine a correction value according to the direction information of the pressure sensor (210) based on the pressure offset data stored according to the method described through FIGS. 9A to 10C. For example, the electronic device (101) can determine an operation method for pressure correction using the pressure offset data of each of the three directions. As an example, the pressure offset data can be as follows.

[0158]

[0159] In [Table 2], 'No' represents a sample number. '1G' represents the first pressure offset data in the first state (1001), '0G' represents the second pressure offset data in the second state (1002), and '-1G' represents the third pressure offset data in the third state (1003). The electronic device (101) can determine the calculation method using the pressure offset data of each sample number. For example, the electronic device (101) can model the relationship between the direction information (e.g., tilting angle) of the pressure sensor (210) and the pressure offset value as a quadratic function. In the first sample number, the electronic device (101) can model the relationship between the direction information (e.g., tilting angle) of the pressure sensor (210) and the pressure offset value as a quadratic function. In the first sample number, the electronic device (101) can determine the calculation method for pressure compensation as 'y = -(7 / 1620000)x 2 - (3 / 18000) x' can be determined. x represents the direction information of the pressure sensor (210), and y represents the pressure offset value to be reflected. In the second sample number, the electronic device (101) is a calculation method for pressure compensation, 'y = -(6 / 1620000)x 2 - (2 / 18000) x' can be determined. x represents the direction information of the pressure sensor (210), and y represents the pressure offset value to be reflected. In the third sample number, the electronic device (101) is a calculation method for pressure compensation, 'y = (4 / 1620000)x 2 - (26 / 18000) x' can be determined. x represents the direction information of the pressure sensor (210), and y represents the pressure offset value to be reflected.

[0160] The electronic device (101) can determine an operation method for pressure compensation using data at three points (e.g., first pressure offset data, second pressure offset data, and third pressure offset data), as illustrated in Table 1. The electronic device (101) can store the operation method internally. The electronic device (101) can obtain direction information of the pressure sensor (210) and then calculate a correction value corresponding to the direction information using the operation method. For example, the electronic device (101) can determine that the pressure sensor (210) is tilted by about 38 degrees from the center direction (e.g., the direction of gravity). The electronic device (101) can determine about 38 degrees as the direction information of the pressure sensor (210). The electronic device (101) can determine a correction value corresponding to about 38 degrees, which is the direction information of the pressure sensor (210), using sample #2. The electronic device (101) can determine a correction value corresponding to approximately -0.00957 hPa. The electronic device (101) can add the correction value to the pressure value measured by the barometric pressure sensor (210) to determine the final pressure information. For another example, the electronic device (101) can determine that the barometric pressure sensor (210) is tilted by approximately 152 degrees from the center direction (e.g., the direction of gravity). The electronic device (101) can determine approximately 152 degrees as the direction information of the barometric pressure sensor (210). The electronic device (101) can use sample #3 to determine a correction value corresponding to approximately 152 degrees, which is the direction information of the barometric pressure sensor (210). The electronic device (101) can determine a correction value corresponding to approximately -0.1625 hPa. The electronic device (101) can add the correction value to the pressure value measured by the barometric pressure sensor (210) to determine the final pressure information.

[0161] Figure 12 illustrates an example of changes in the accuracy of measured pressure depending on the degree of rotation of a pressure sensor (e.g., pressure sensor (210)). The degree of rotation represents the angle of inclination of the pressure sensor from its rotational axis (e.g., from the arm to the hand), i.e., the roll value. The degree of rotation can be indicated through the direction information of the pressure sensor (210).

[0162] Referring to FIG. 12, a graph (1200) represents a change in accuracy of measured pressure versus the degree of rotation. The horizontal axis of the graph (1200) represents the degree of rotation (unit: degree), and the vertical axis of the graph (1200) represents a change in accuracy of measured pressure (unit: hPa). Referring to the graph (1200), it can be confirmed that the value of the change in accuracy is about -0.04 hPa when it is about 45 degrees. If the direction information (e.g., roll value) of the pressure sensor (210) is about 0 degrees, about 90 degrees, and about 180 degrees, and the pressure offset data indicates about 0 hPa, about -0.09 hPa, and about -0.17 hPa, respectively, the operation method can be modeled by the following mathematical equation.

[0163]

[0164] The above mathematical formula (7) is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical formula (7) may be modified, applied, or expanded in various ways.

[0165] x represents the direction information of the pressure sensor (210), and y represents the pressure offset value to be reflected. For example, when x is about 45 degrees, the correction value is about -0.04625 hPa. When the pressure sensor (210) is tilted by about 45 degrees, the actual offset is about -0.04 hPa. Therefore, an error occurs by a difference of about 0.00625 hPa. However, this level of error is less than about 10 cm, and can be understood as a negligible level.

[0166] FIG. 13 illustrates an operation flow of an electronic device (e.g., electronic device (101)) for determining direction information of an inertial sensor (e.g., inertial sensor (230)). The direction information of the inertial sensor (230) may indicate the degree of inclination of the inertial sensor (230). For example, the direction information of the inertial sensor (230) may indicate an angular difference between the surface on which the inertial sensor (230) is placed and the ground.

[0167] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0168] Referring to FIG. 13, according to one embodiment, in operation (1301), the electronic device (101) (e.g., the processor (120)) may determine a state parameter using sensing data. The electronic device (101) may obtain sensing data from the inertial sensor (230). The electronic device (101) may determine a state parameter related to acceleration using the sensing data. The state parameter may be used to determine whether the electronic device (101) is in a stable state. For example, the state parameter may represent acceleration variance. To determine the acceleration variance, the electronic device (101) may determine the magnitude of the acceleration at each time sample. For example, the magnitude of the acceleration may be determined according to the following mathematical equation.

[0169]

[0170] The above mathematical expression (8) is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical expression (8) may be modified, applied, or expanded in various ways.

[0171] 'Magnitude' indicates the size of acceleration. 'acc x' represents the x-axis acceleration value of the inertial sensor (230). 'acc y ' represents the y-axis acceleration value of the inertial sensor (230). 'acc z ' represents the z-axis acceleration value of the inertial sensor (230).

[0172] For example, the state parameter may represent an amount of change in an angle (e.g., a tilting angle inclination). The electronic device (101) may determine the tilting angle to determine the amount of change in the angle. As an example, the tilting angle may be determined according to the following mathematical equation.

[0173]

[0174] The above mathematical equation (9) is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical equation (9) may be modified, applied, or expanded in various ways.

[0175] 'Z axis angle' represents the angle of inclination relative to the direction perpendicular to the ground (e.g., the (+)z axis). 'Magnitude' represents the magnitude of acceleration. 'acc z ' represents the z-axis acceleration value of the inertial sensor (230).

[0176] According to one embodiment, in operation (1303), the electronic device (101) (e.g., the processor (120)) may determine whether the electronic device (101) is in a stable state. The electronic device (101) may use the state parameter to determine whether the electronic device (101) is in a stable state. For example, the electronic device (101) may determine whether an acceleration dispersion is greater than a threshold value. If the acceleration dispersion is greater than the threshold value, the acceleration changes rapidly, and the electronic device (101) may determine that the state of the electronic device (101) is not stable. If the acceleration dispersion is less than or equal to the threshold value, the electronic device (101) may determine that the state of the electronic device (101) is stable. For example, the electronic device (101) may determine whether an amount of change in an angle of the inertial sensor (230) is within a threshold range. For example, the threshold range may represent a range of less than (+) error from a reference value and greater than (-) error from the reference value. The amount of change in the angle may represent the inclination of the angle of the inertial sensor (230). If the amount of change in the angle is substantially fixed within the error range from the reference value, the movement of the electronic device (101) may be understood as linear. If the amount of change in the angle of the inertial sensor (230) is outside the threshold range, the electronic device (101) may determine that the state of the electronic device (101) is not stable. If the amount of change in the angle of the inertial sensor (230) is within the threshold range, the electronic device (101) may determine that the state of the electronic device (101) is stable. If the state of the electronic device (101) is determined to be stable, the electronic device (101) may perform operation (1305). If the state of the electronic device (101) is determined to be unstable, the electronic device (101) may perform operation (1307).

[0177] According to one embodiment, in operation (1305), the electronic device (101) (e.g., the processor (120)) may determine direction information of the inertial sensor (210) from sensing data. Since the electronic device (101) can trust the sensing data of the inertial sensor (210), the electronic device (101) may determine direction information of the inertial sensor (210) using the sensing data. The direction information of the inertial sensor (210) may indicate a rotation axis and an inclination from the rotation axis. The electronic device (101) may determine information about the rotation axis (hereinafter, rotation axis information) and an inclination from the rotation axis (hereinafter, rotation angle) from the sensing data of the inertial sensor (210). For example, the direction information may be determined based on roll, pitch, and / or yaw measured by the inertial sensor (210). As an example, the rotation information may be determined according to the following mathematical equations.

[0178]

[0179] The above mathematical expression (10) is merely an example to aid understanding, and embodiments of the present disclosure may not be limited thereto. For example, the above mathematical expression (10) may be modified, applied, or expanded in various ways.

[0180] Roll represents a roll value measured through an inertial sensor (210), Pitch represents a pitch value measured through an inertial sensor (210), and Yaw represents a yaw value measured through an inertial sensor (210).

[0181]

[0182] The above mathematical expression (11) is merely an example to aid understanding, and the embodiments of the present disclosure may not be limited thereto. For example, the above mathematical expression (11) may be modified, applied, or expanded in various ways.

[0183] R represents the rotation matrix.

[0184]

[0185] The above mathematical expression (12) is merely an example to aid understanding, and the embodiments of the present disclosure may not be limited thereto. For example, the above mathematical expression (12) may be modified, applied, or expanded in various ways.

[0186] p represents rotation axis information (e.g., a vector representing the rotation axis), and α represents a rotation angle from the rotation axis.

[0187] According to one embodiment, in operation (1307), the electronic device (101) (e.g., the processor (120)) can determine the direction information of the inertial sensor (210) through the previous sensing data and rotation information. Since the electronic device (101) cannot trust the sensing data of the inertial sensor (210), the previous sensing data can be used. The previous sensing data represents the most recent sensing data when the electronic device (101) is in a stable state. In other words, the state parameter according to the previous sensing data can indicate that the electronic device (101) is in a stable state. The electronic device (101) can obtain rotation information. The rotation information represents a difference in the rotation angle of the electronic device (101) between the previous sensing data and the sensing data of operation (1301). The electronic device (101) can directly calculate the direction in which the current inertial sensor (230) is facing by using the difference in the rotated angle.

[0188] The direction information of the inertial sensor (230) acquired through FIG. 13 may be used to determine the direction information of the pressure sensor (210). Prior to determining the direction information of the pressure sensor (210), as a non-limiting example, the direction information of the inertial sensor (230) may be filtered. The electronic device (101) may pass the direction information of the inertial sensor (230) through at least one filter. The at least one filter may be used to reduce the problem of an error increasing due to a rapid angle change. For example, the at least one filter may include an average filter. The at least one filter may include a Hampel filter. For example, the inertial sensor (230) may output sensing data 10 times during a unit time, while the pressure sensor (210) may measure pressure data 3 times. Due to the difference in ODR (output data rate) between the inertial sensor (230) and the barometric pressure sensor (210), it may be difficult for the barometric pressure sensor (210) to sufficiently reflect the amount of change in the inertial sensor (230). To prevent errors due to the ODR difference and to prevent an inaccurate offset correction value from being applied to the barometric pressure sensor (210) in a situation where an impact is applied other than a simple drop (e.g., a fall), at least one filter may be used. The electronic device (101) may determine the direction information of the barometric pressure sensor (210) using the direction information of the inertial sensor (230) that has passed through the at least one filter (hereinafter, referred to as filtered direction information). The electronic device (101) may determine a correction value for pressure using the direction information of the barometric pressure sensor (210) in a calculation method derived using pressure offset data. The electronic device (101) may determine a correction value corresponding to the direction information of the barometric pressure sensor (210).

[0189] Fig. 14 illustrates an operation flow of an electronic device (e.g., electronic device (101)) for providing pressure information using pressure offset data. The pressure offset data is a posture correction value of the electronic device (101) and can be used to correct pressure information. The pressure correction procedure described through Figs. 2 to 13 may increase power consumption of the electronic device (101) because it is necessary to continuously acquire and correct sensing data through the inertial sensor (230). To reduce power consumption, the electronic device (101) may perform a pressure correction procedure using the posture correction value only in specific situations.

[0190] In the following examples, the operations may be performed sequentially, but are not necessarily sequential. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0191] Referring to FIG. 14, according to one embodiment, in operation 1401, the electronic device (101) (e.g., processor (120)) may determine whether a designated application is running. The designated application may be an application requiring more precise altitude measurement (or depth measurement). For example, the application may be a health application. For example, the application may be a sleep application. For example, the application may be a swimming application. For example, the application may be a fishing application. For example, the application may be an application for triggering an emergency call. If the designated application is running, the electronic device (101) may perform operation 1403. If the designated application is not running, the electronic device (101) may terminate the procedure of FIG. 14. Although not shown in FIG. 14, the electronic device (101) can provide pressure information (e.g., altitude, depth) using pressure values ​​measured through the pressure sensor (210) without direction-specific correction values.

[0192] According to one embodiment, in operation (1403), the electronic device (101) may provide pressure information using a posture correction value. Using the posture correction value may include reflecting a correction value determined according to the direction of the pressure sensor (210) using the pressure offset data described through FIGS. 2 to 13 to the measured pressure.

[0193] Although an example in which a pressure compensation procedure using a posture compensation value is initiated in response to the execution of a designated application is described in FIG. 14, embodiments of the present disclosure are not limited thereto. The electronic device (101) may be configured to constantly perform the compensation procedure using the pressure offset data described through FIGS. 2 to 13. The electronic device (101) may provide pressure information regardless of the execution of a separate application. For example, the electronic device (101) may continuously monitor the movement of the electronic device (101) and, in response to the result of the movement of the electronic device (101), perform the pressure compensation procedure using the posture compensation value. Meanwhile, as a non-limiting example, when the remaining battery of the electronic device (101) is insufficient (e.g., a battery condition below a designated threshold) or the electronic device (101) operates in a specific mode (e.g., a low-power mode), the pressure compensation procedure using the posture compensation value may be performed manually without performing the pressure compensation procedure using the posture compensation value in real time. Additionally, for example, instead of executing a specified application, the pressure compensation procedure using the posture compensation value may be performed in a specific mode of the electronic device (101) (e.g., high performance mode, battery optimization exclusion mode).

[0194] Fig. 15 illustrates an example of a pressure measurement result. Fig. 15 illustrates examples of pressure information in which pressure correction is reflected using a correction value according to the posture (or state) of the electronic device (101) described through Figs. 2 to 14.

[0195] Referring to FIG. 15, a graph (1500) represents a change in a pressure value measured in an electronic device (101) when the electronic device (101) is dropped from a certain height from the ground. The horizontal axis of the graph (1500) represents time (unit: sample index), and the vertical axis of the graph (1500) represents pressure (unit: hPa (hectopascal)). As the electronic device (101) falls, the closer the electronic device (101) gets to the ground, the greater the atmospheric pressure the electronic device (101) experiences.

[0196] At a first point (1501), the electronic device (101) may begin to fall. At a second point (1502), the electronic device (101) may rotate. Due to the rotation, the direction information of the pressure sensor (210) of the electronic device (101) may change. The direction in which the pressure-sensitive surface of the sensing element (310) within the pressure sensor (210) faces may change. At a third point (1503), the electronic device (101) may perform pressure compensation. Since the gravity applied by the waterproof member (330) within the pressure sensor (210) to the pressure-sensitive surface varies depending on the direction in which the pressure-sensitive surface faces, the electronic device (101) may determine a compensation value according to the direction. The electronic device (101) may reflect the compensation value to the pressure data measured by the pressure sensor (210) to determine a final pressure value. The electronic device (101) may output the final pressure value to the user. The final pressure value corresponds to the vertical axis of Fig. 15. At the fourth point (1504), the electronic device (101) can touch the ground. Referring to the first point (1501), the second point (1502), the third point (1503), and the fourth point (1504), it can be confirmed that the pressure measured by the electronic device (101) gradually increases while the electronic device (101) is falling through pressure compensation according to the direction of the atmospheric pressure sensor (210). In fact, since the atmospheric pressure increases due to the falling of the electronic device (101), the electronic device (101) can provide pressure information that matches the user's intention.

[0197] Figure 16 illustrates an example of a wearable device. The posture-dependent pressure compensation procedure described in Figures 2 to 15 can be applied not only to electronic devices such as smartphones or wearable devices such as wristwatches, but also to various types of wearable devices.

[0198] Referring to FIG. 16, an exemplary wearable device (e.g., the electronic device (101) of FIG. 1) may be used while being worn on a user's body. For example, the exemplary wearable device (101) may include a ring-shaped housing (1620) that may be worn on a user's finger. For example, the housing (1620) may form the exterior of the wearable device (101). For example, the size of the housing (1620) may be determined based on the body part on which the wearable device (101) is worn. Since the wearable device (101) is used while being worn on a user's body, the size of the housing (1620) may be limited. For example, if the wearable device (101) is a ring-shaped device, the housing (1620) may be limited to a size that may be worn on a finger. The wearable device (101) including the ring-shaped housing (1620) may be implemented as a ring-shaped device that can be worn on a user's finger. In the present disclosure, for convenience of explanation, the wearable device (101) is described as a ring-shaped device, but is not limited thereto. For example, the wearable device (101) may include an earring-shaped device that can be worn on a user's ear, a bracelet-shaped device that can be worn on a user's arm, and / or a headband-shaped device that can be worn on a user's head. The wearable device (101) may be used while being worn on a user's body. For example, the wearable device (101) may be configured to communicate with an external electronic device (102) (e.g., a smartphone) while being worn on a user's body.

[0199] The wearable device (101) may include a barometric pressure sensor (210) and an inertial sensor (230). As a non-limiting example, within the wearable device (101), due to spatial limitations, the barometric pressure sensor (210) and the inertial sensor (230) may be arranged on different planes. For example, the pressure-sensitive surface of the sensing element (310) of the barometric pressure sensor (210) may be arranged to face gravity, and the inertial sensor (230) may be arranged to face in a direction opposite to gravity. The wearable device (101) may determine the direction information of the barometric pressure sensor (210) by using the direction information and the angle difference (e.g., about 180 degrees) of the inertial sensor (230). The direction information of the barometric pressure sensor (210) may indicate the angle at which the barometric pressure sensor (210) rotates with a finger as the rotation axis. The wearable device (101) can determine a correction value according to the direction information of the pressure sensor (210) based on an operation method for pressure compensation. In FIGS. 9A to 12, examples of using pressure offset data for each of the three directions to determine the operation method are described, but the embodiments of the present disclosure are not limited thereto. When the wearable device (101) is a ring-shaped device, the user's rotation radius may be wider than 180 degrees. Therefore, the wearable device (101) can determine the operation method using four or more pieces of pressure offset data.

[0200] The wearable device (101) can perform pressure compensation by using the angular difference between the pressure sensor (210) and the inertial sensor (230). As a non-limiting example, in the case of a ring-shaped device, the angular difference between the pressure sensor (210) and the inertial sensor (230) may vary depending on the size of the housing (1620). Therefore, according to one embodiment, the angular difference value between the pressure sensor (210) and the inertial sensor (230) depending on the size of the housing (1620) may be stored inside the pressure sensor (210). The wearable device (101) can obtain the angular difference according to the size (e.g., number of 'ho') of the housing (1620) from the pressure sensor (210). According to another embodiment, the wearable device (101) can obtain information about the angular difference between the pressure sensor (210) and the inertial sensor (230) from an external device. For example, the wearable device (101) can provide identification information of the wearable device (101) to an external device and obtain information on an angular difference corresponding to the identification information from the external device.

[0201] Figure 17 illustrates an example of a wearable device. The posture-dependent pressure compensation procedure described in Figures 2 to 15 can be applied not only to electronic devices such as smartphones or wearable devices such as wristwatches, but also to various types of wearable devices.

[0202] Referring to FIG. 17, an exemplary wearable device (e.g., the electronic device (101) of FIG. 1) may be used while being worn on a user's body. For example, the exemplary wearable device (101) may include a head-mounted display (HMD) that is wearable on the head of a user (110). The wearable device (101) may be referred to as a head-mounted device (HMD), a headgear electronic device, a glasses-type electronic device, a video see-through (VST) device, an extended reality (XR) device, a virtual reality (VR) device, and / or an augmented reality (AR) device. Although the external appearance of the wearable device (101) having a glasses-type shape is illustrated, the embodiment is not limited thereto. An example of the structure of a wearable device (101) that can be worn on the head of a user (110) is described with reference to FIGS. 18A, 18B, 19A, and / or 19B. The wearable device (101) may be referred to as an electronic device. For example, the electronic device may be combined with an accessory (e.g., a strap) for attaching to the head of a user to form an HMD.

[0203] According to one embodiment, a wearable device (101) may perform functions related to augmented reality (AR) and / or mixed reality (MR). For example, when a user (110) wears the wearable device (101), the wearable device (101) may include at least one lens positioned adjacent to the user's (110) eyes. The wearable device (101) may combine ambient light passing through the lens with light emitted from a display of the wearable device (101). A display area of ​​the display may be formed within the lens through which the ambient light passes. Because the wearable device (101) combines the ambient light and the light emitted from the display, the user (110) may see an image that is a mixture of a real object recognized by the ambient light and a virtual object formed by the light emitted from the display. The augmented reality, mixed reality, and / or virtual reality described above may be referred to as extended reality (XR).

[0204] In one embodiment, a wearable device (101) may perform functions related to video see-through (VST) and / or virtual reality (VR). For example, when a user (110) wears the wearable device (101), the wearable device (101) may include a housing that covers the eyes of the user (110). The wearable device (101), in this state, may include a display disposed on a first side of the housing facing the eyes. The wearable device (101) may include a camera disposed on a second side opposite the first side. Using the camera, the wearable device (101) may acquire images and / or videos representing ambient light. The wearable device (101) can output the image and / or video within the display disposed on the first surface, thereby allowing the user (110) to recognize the ambient light through the display. The displaying area (or displaying region) (or active area or active region) of the display disposed on the first surface can be formed by one or more pixels included in the display. The wearable device (101) can synthesize a virtual object into the image and / or video output through the display, thereby allowing the user (110) to recognize the virtual object together with a real object recognized by the ambient light.

[0205] The wearable device (101) may include a barometric pressure sensor (210) and an inertial sensor (230). As a non-limiting example, within the wearable device (101), due to spatial limitations, the barometric pressure sensor (210) and the inertial sensor (230) may be arranged on different planes. For example, the pressure-sensitive surface of the sensing element (310) of the barometric pressure sensor (210) may be arranged to face a direction perpendicular to gravity, and the inertial sensor (230) may be arranged to face a direction opposite to gravity. The wearable device (101) may determine the direction information of the barometric pressure sensor (210) by using the direction information and the angular difference (e.g., about 90 degrees) of the inertial sensor (230). The direction information of the pressure sensor (210) may indicate the angle at which the pressure sensor (210) rotates based on the direction from the user's torso to the head (e.g., (+) z-axis direction) as the rotation axis, or may indicate the angle at which the pressure sensor (210) rotates based on the direction parallel to the ground and penetrating the user's neck (e.g., (-) x-axis direction, (+) y-axis direction). In the case of a wearable device of the HMD type, since the user's degree of freedom of rotation is high, the direction information of the pressure sensor (210) may indicate both the roll value and the pitch value (or, as another example, the direction information may indicate all of the roll value, the pitch value, and the yaw value). When determining the calculation method, the wearable device (101) may determine a correction value corresponding to the direction information of the pressure sensor (210) through a calculation method that utilizes two or more variables (e.g., roll angle, pitch angle, yaw angle).

[0206]

[0207] The above mathematical expression (13) is merely an example to aid understanding, and the embodiments of the present disclosure may not be limited thereto. For example, the above mathematical expression (13) may be modified, applied, or expanded in various ways.

[0208] x represents a first value (e.g., roll value) among the direction information of the pressure sensor (210), and z represents a second value (e.g., pitch value) among the direction information of the pressure sensor (210). f(a, b) represents an operation function for pressure compensation, with a and b as variables. y represents a pressure offset value to be reflected.

[0209] The wearable device (101) can determine a correction value according to the direction information of the pressure sensor (210) based on the calculation method for the pressure compensation. In FIGS. 9A to 12, examples of using pressure offset data for each of the three directions to determine the calculation method are described, but the embodiments of the present disclosure are not limited thereto. When the wearable device (101) is an HMD type wearable device, the user's rotation axis may vary. In order to more accurately derive the calculation method, the wearable device (101) can determine the calculation method using four or more pieces of pressure offset data.

[0210] Fig. 18a illustrates an example of a perspective view of a wearable device. Fig. 18b illustrates an example of one or more hardware components arranged within the wearable device. According to one embodiment, the wearable device (101) may have a form of glasses that can be worn on a body part (e.g., head) of a user. The wearable device (101) of Figs. 18a and 18b may be an example of the wearable device (101) of Fig. 17. The wearable device (101) may include a head-mounted display (HMD). For example, the housing of the wearable device (101) may include a flexible material, such as rubber and / or silicone, that is configured to fit closely to a portion of the user's head (e.g., a portion of the face surrounding both eyes). For example, the housing of the wearable device (101) may include one or more straps capable of being twined around the user's head, and / or one or more temples attachable to the ears of the head.

[0211] Referring to FIG. 18A, according to one embodiment, a wearable device (101) may include at least one display (1850) and a frame (1800) supporting at least one display (1850).

[0212] According to one embodiment, a wearable device (101) can be worn on a part of a user's body. The wearable device (101) can provide augmented reality (AR), virtual reality (VR), or mixed reality (MR) that combines augmented reality and virtual reality to a user wearing the wearable device (101). For example, the wearable device (101) can display a virtual reality image provided from at least one optical device (1882, 1884) of FIG. 18B on at least one display (1850) in response to a user's designated gesture acquired through the motion recognition cameras (1860-2, 1860-3) of FIG. 18B.

[0213] According to one embodiment, at least one display (1850) may provide visual information to a user. For example, at least one display (1850) may include a transparent or translucent lens. At least one display (1850) may include a first display (1850-1) and / or a second display (1850-2) spaced apart from the first display (1850-1). For example, the first display (1850-1) and the second display (1850-2) may be positioned at positions corresponding to the user's left and right eyes, respectively.

[0214] Referring to FIG. 18B, at least one display (1850) can provide the user with visual information transmitted from external light and other visual information distinct from the visual information through a lens included in the at least one display (1850). The lens can be formed based on at least one of a Fresnel lens, a pancake lens, or a multi-channel lens. For example, the at least one display (1850) can include a first surface (1831) and a second surface (1832) opposite the first surface (1831). A display area can be formed on the second surface (1832) of the at least one display (1850). When the user wears the wearable device (101), external light can be transmitted to the user by being incident on the first surface (1831) and transmitted through the second surface (1832). As another example, at least one display (1850) can display an augmented reality image combined with a virtual reality image provided from at least one optical device (1882, 1884) on a real screen transmitted through external light, in a display area formed on the second surface (1832).

[0215] In one embodiment, at least one display (1850) may include at least one waveguide (1833, 1834) that diffracts light emitted from at least one optical device (1882, 1884) and transmits the diffracted light to a user. The at least one waveguide (1833, 1834) may be formed based on at least one of glass, plastic, or polymer. A nanopattern may be formed on at least a portion of the exterior or interior of the at least one waveguide (1833, 1834). The nanopattern may be formed based on a grating structure having a polygonal and / or curved shape. Light incident on one end of the at least one waveguide (1833, 1834) may be propagated to the other end of the at least one waveguide (1833, 1834) by the nanopattern. At least one waveguide (1833, 1834) may include at least one diffractive element (e.g., a diffractive optical element (DOE), a holographic optical element (HOE)), or at least one reflective element (e.g., a reflective mirror). For example, at least one waveguide (1833, 1834) may be positioned within the wearable device (101) to guide a screen displayed by at least one display (1850) to the user's eyes. For example, the screen may be transmitted to the user's eyes based on total internal reflection (TIR) ​​occurring within the at least one waveguide (1833, 1834).

[0216] The wearable device (101) can analyze an object included in a real image collected through a shooting camera (1860-4), combine a virtual object corresponding to an object to be provided with augmented reality among the analyzed objects, and display the virtual object on at least one display (1850). The virtual object can include at least one of text and an image regarding various information related to the object included in the real image. The wearable device (101) can analyze the object based on a multi-camera such as a stereo camera. For the object analysis, the wearable device (101) can perform spatial recognition (e.g., simultaneous localization and mapping (SLAM)) using a multi-camera and / or time-of-flight (ToF). A user wearing the wearable device (101) can view an image displayed on at least one display (1850).

[0217] According to one embodiment, the frame (1800) may be formed as a physical structure that allows the wearable device (101) to be worn on the user's body. According to one embodiment, the frame (1800) may be configured so that, when the user wears the wearable device (101), the first display (1850-1) and the second display (1850-2) can be positioned corresponding to the user's left and right eyes. The frame (1800) may support at least one display (1850). For example, the frame (1800) may support the first display (1850-1) and the second display (1850-2) to be positioned corresponding to the user's left and right eyes.

[0218] Referring to FIG. 18A, the frame (1800) may include a region (1820) that at least partially contacts a portion of the user's body when the user wears the wearable device (101). For example, the region (1820) of the frame (1800) that contacts a portion of the user's body may include a region that contacts a portion of the user's nose, a portion of the user's ear, and a portion of the side of the user's face that the wearable device (101) makes contact with. According to one embodiment, the frame (1800) may include a nose pad (1810) that contacts a portion of the user's body. When the wearable device (101) is worn by the user, the nose pad (1810) may contact a portion of the user's nose. The frame (1800) may include a first temple (1804) and a second temple (1805) that contact another part of the user's body that is distinct from the part of the user's body.

[0219] For example, the frame (1800) may include a first rim (1801) that surrounds at least a portion of the first display (1850-1), a second rim (1802) that surrounds at least a portion of the second display (1850-2), a bridge (1803) that is disposed between the first rim (1801) and the second rim (1802), a first pad (1811) that is disposed along a portion of the edge of the first rim (1801) from one end of the bridge (1803), a second pad (1812) that is disposed along a portion of the edge of the second rim (1802) from the other end of the bridge (1803), a first temple (1804) that extends from the first rim (1801) and is fixed to a portion of the ear of the wearer, and a second temple (1805) that extends from the second rim (1802) and is fixed to a portion of the ear opposite the ear. There are. The first pad (1811) and the second pad (1812) can be in contact with a part of the user's nose, and the first temple (1804) and the second temple (1805) can be in contact with a part of the user's face and a part of the user's ear. The temples (1804, 1805) can be rotatably connected to the rim through the hinge units (1806, 1807) of FIG. 18B. The first temple (1804) can be rotatably connected to the first rim (1801) through the first hinge unit (1806) disposed between the first rim (1801) and the first temple (1804). The second temple (1805) may be rotatably connected to the second rim (1802) via a second hinge unit (1807) disposed between the second rim (1802) and the second temple (1805). In one embodiment, the wearable device (101) may use a touch sensor, a grip sensor, and / or a proximity sensor formed on at least a portion of a surface of the frame (1800) to identify an external object (e.g., a user's fingertip) touching the frame (1800) and / or a gesture performed by the external object.

[0220] According to one embodiment, the wearable device (101) may include hardwares (e.g., hardwares in the block diagram of FIG. 2) that perform various functions. For example, the hardwares may include a battery module (1870), an antenna module (1875), at least one optical device (1882, 1884), speakers (e.g., speakers 1855-1, 1855-2), a microphone (e.g., microphones 1865-1, 1865-2, 1865-3), a light-emitting module (not shown), and / or a printed circuit board (PCB) (1890) (e.g., a printed circuit board). The various hardwares may be arranged within a frame (1800).

[0221] According to one embodiment, microphones (e.g., microphones 1865-1, 1865-2, 1865-3) of the wearable device (101) may be disposed on at least a portion of the frame (1800) to acquire sound signals. A first microphone (1865-1) disposed on the bridge (1803), a second microphone (1865-2) disposed on the second rim (1802), and a third microphone (1865-3) disposed on the first rim (1801) are illustrated in FIG. 18B , but the number and arrangement of the microphones (1865) are not limited to the embodiment of FIG. 18B . When the number of microphones (1865) included in the wearable device (101) is two or more, the wearable device (101) can identify the direction of a sound signal by using a plurality of microphones arranged on different parts of the frame (1800).

[0222] According to one embodiment, at least one optical device (1882, 1884) may project a virtual object onto at least one display (1850) to provide various image information to a user. For example, at least one optical device (1882, 1884) may be a projector. At least one optical device (1882, 1884) may be disposed adjacent to at least one display (1850) or may be included within at least one display (1850) as a part of at least one display (1850). According to one embodiment, the wearable device (101) may include a first optical device (1882) corresponding to a first display (1850-1) and a second optical device (1884) corresponding to a second display (1850-2). For example, at least one optical device (1882, 1884) may include a first optical device (1882) positioned at an edge of a first display (1850-1) and a second optical device (1884) positioned at an edge of a second display (1850-2). The first optical device (1882) may transmit light to a first waveguide (1833) positioned on the first display (1850-1), and the second optical device (1884) may transmit light to a second waveguide (1834) positioned on the second display (1850-2).

[0223] In one embodiment, the camera (1860) may include a recording camera (1860-4), an eye tracking camera (ET CAM) (1860-1), and / or a motion recognition camera (1860-2, 1860-3). The recording camera (1860-4), the eye tracking camera (1860-1), and the motion recognition cameras (1860-2, 1860-3) may be positioned at different locations on the frame (1800) and may perform different functions. The eye tracking camera (1860-1) may output data indicating the position or gaze of the eyes of a user wearing the wearable device (101). For example, the wearable device (101) may detect the gaze from an image including the user's pupils obtained through the eye tracking camera (1860-1). The wearable device (101) can identify an object (e.g., a real object and / or a virtual object) focused on by the user using the user's gaze acquired through the gaze tracking camera (1860-1). The wearable device (101) that has identified the focused object can execute a function (e.g., gaze interaction) for interaction between the user and the focused object. The wearable device (101) can express a part corresponding to the eye of an avatar representing the user in a virtual space using the user's gaze acquired through the gaze tracking camera (1860-1). The wearable device (101) can render an image (or screen) displayed on at least one display (1850) based on the position of the user's eyes. For example, the visual quality of a first region related to the gaze within the image and the visual quality (e.g., resolution, brightness, saturation, grayscale, PPI) of a second region distinguished from the first region may be different from each other.The wearable device (101) can obtain an image having a visual quality of a first area matching the user's gaze and a visual quality of a second area using foveated rendering. For example, if the wearable device (101) supports an iris recognition function, user authentication can be performed based on iris information obtained using a gaze tracking camera (1860-1). An example in which the gaze tracking camera (1860-1) is positioned toward the user's right eye is illustrated in FIG. 18B, but the embodiment is not limited thereto, and the gaze tracking camera (1860-1) can be positioned solely toward the user's left eye, or toward both eyes.

[0224] In one embodiment, the capturing camera (1860-4) can capture an actual image or background to be aligned with a virtual image to implement augmented reality or mixed reality content. The capturing camera (1860-4) can be used to obtain a high-resolution image based on HR (high resolution) or PV (photo video). The capturing camera (1860-4) can capture an image of a specific object existing at a location viewed by the user and provide the image to at least one display (1850). The at least one display (1850) can display a single image in which information about an actual image or background including an image of the specific object obtained using the capturing camera (1860-4) and a virtual image provided through at least one optical device (1882, 1884) are superimposed. The wearable device (101) can compensate for depth information (e.g., the distance between the wearable device (101) and an external object acquired through a depth sensor) using an image acquired through the capture camera (1860-4). The wearable device (101) can perform object recognition using an image acquired using the capture camera (1860-4). The wearable device (101) can perform a function of focusing on an object (or subject) in an image (e.g., auto focus) and / or an optical image stabilization (OIS) function (e.g., anti-shake function) using the capture camera (1860-4). The wearable device (101) can perform a pass-through function to display an image acquired through the capture camera (1860-4) by overlapping at least a portion of a screen representing a virtual space on at least one display (1850) while displaying the screen. In one embodiment, the camera (1860-4) may be positioned on a bridge (1803) positioned between the first rim (1801) and the second rim (1802).

[0225] The gaze tracking camera (1860-1) can implement more realistic augmented reality by tracking the gaze of a user wearing a wearable device (101) and matching the user's gaze with visual information provided to at least one display (1850). For example, when the wearable device (101) looks straight ahead, the wearable device (101) can naturally display environmental information related to the user's front at a location where the user is located on at least one display (1850). The gaze tracking camera (1860-1) can be configured to capture an image of the user's pupil to determine the user's gaze. For example, the gaze tracking camera (1860-1) can receive gaze detection light reflected from the user's pupil and track the user's gaze based on the position and movement of the received gaze detection light. In one embodiment, the gaze tracking camera (1860-1) can be positioned at positions corresponding to the user's left and right eyes. For example, the gaze tracking camera (1860-1) may be positioned within the first rim (1801) and / or the second rim (1802) to face the direction in which the user wearing the wearable device (101) is positioned.

[0226] The gesture recognition cameras (1860-2, 1860-3) can provide a specific event on a screen provided on at least one display (1850) by recognizing the movement of the user's entire body or a part of the user's body, such as the user's torso, hands, or face. The gesture recognition cameras (1860-2, 1860-3) can recognize the user's gesture (gesture recognition), obtain a signal corresponding to the gesture, and provide a display corresponding to the signal on at least one display (1850). The processor can identify the signal corresponding to the gesture and perform a designated function based on the identification. The gesture recognition cameras (1860-2, 1860-3) can be used to perform a spatial recognition function using SLAM and / or a depth map for 6 degrees of freedom pose (6 dof pose). The processor may perform gesture recognition and / or object tracking functions using the motion recognition cameras (1860-2, 1860-3). In one embodiment, the motion recognition cameras (1860-2, 1860-3) may be positioned on the first rim (1801) and / or the second rim (1802).

[0227] The camera (1860) included in the wearable device (101) is not limited to the above-described gaze tracking camera (1860-1) and motion recognition cameras (1860-2, 1860-3). For example, the wearable device (101) can identify an external object included in the user's field of view (FoV) using a camera positioned toward the FoV. The wearable device (101) can identify an external object based on a sensor for identifying the distance between the wearable device (101) and the external object, such as a depth sensor and / or a time of flight (ToF) sensor. The camera (1860) positioned toward the FoV can support an autofocus function and / or an optical image stabilization (OIS) function. For example, the wearable device (101) may include a camera (1860) (e.g., a face tracking (FT) camera) positioned toward the face to obtain an image including the face of a user wearing the wearable device (101).

[0228] Although not shown, in one embodiment, the wearable device (101) may further include a light source (e.g., an LED) that emits light toward a subject (e.g., a user's eyes, face, and / or an external object within the FoV) being captured using the camera (1860). The light source may include an infrared wavelength LED. The light source may be disposed on at least one of the frame (1800) and the hinge units (1806, 1807).

[0229] According to one embodiment, the battery module (1870) may supply power to the electronic components of the wearable device (101). In one embodiment, the battery module (1870) may be disposed within the first temple (1804) and / or the second temple (1805). For example, the battery module (1870) may be a plurality of battery modules (1870). The plurality of battery modules (1870) may be disposed within each of the first temple (1804) and the second temple (1805). In one embodiment, the battery module (1870) may be disposed at an end of the first temple (1804) and / or the second temple (1805).

[0230] The antenna module (1875) can transmit signals or power to the outside of the wearable device (101), or receive signals or power from the outside. In one embodiment, the antenna module (1875) can be positioned within the first temple (1804) and / or the second temple (1805). For example, the antenna module (1875) can be positioned close to one surface of the first temple (1804) and / or the second temple (1805).

[0231] The speaker (1855) can output an audio signal to the outside of the wearable device (101). The audio output module may be referred to as a speaker. In one embodiment, the speaker (1855) may be positioned within the first temple (1804) and / or the second temple (1805) so as to be positioned adjacent to the ear of a user wearing the wearable device (101). For example, the speaker (1855) may include a second speaker (1855-2) positioned within the first temple (1804) and thus positioned adjacent to the user's left ear, and a first speaker (1855-1) positioned within the second temple (1805) and thus positioned adjacent to the user's right ear.

[0232] The light-emitting module (not shown) may include at least one light-emitting element. The light-emitting module may emit light of a color corresponding to a specific state or emit light with an action corresponding to a specific state in order to visually provide information regarding a specific state of the wearable device (101) to the user. For example, when the wearable device (101) requires charging, it may emit red light at a regular cycle. In one embodiment, the light-emitting module may be disposed on the first rim (1801) and / or the second rim (1802).

[0233] Referring to FIG. 18B, according to one embodiment, a wearable device (101) may include a printed circuit board (PCB) (1890). The PCB (1890) may be included in at least one of the first temple (1804) or the second temple (1805). The PCB (1890) may include an interposer disposed between at least two sub-PCBs. One or more hardwares included in the wearable device (101) (e.g., hardwares illustrated by blocks in FIG. 2) may be disposed on the PCB (1890). The wearable device (101) may include a flexible PCB (FPCB) for interconnecting the hardwares.

[0234] According to one embodiment, a wearable device (101) may include at least one of a gyro sensor (e.g., an inertial sensor (230)), a gravity sensor, and / or an acceleration sensor (e.g., an inertial sensor (230)) for detecting a posture of the wearable device (101) and / or a posture of a body part (e.g., a head) of a user wearing the wearable device (101). Each of the gravity sensor and the acceleration sensor may measure gravitational acceleration and / or acceleration based on mutually perpendicular designated three-dimensional axes (e.g., an x-axis, a y-axis, and a z-axis). The gyro sensor may measure an angular velocity of each of the designated three-dimensional axes (e.g., an x-axis, a y-axis, and a z-axis). At least one of the gravity sensor, the acceleration sensor, and the gyro sensor may be referred to as an inertial measurement unit (IMU). According to one embodiment, the wearable device (101) may identify a user's motion and / or gesture performed to execute or terminate a specific function of the wearable device (101) based on the IMU.

[0235] Figures 19a and 19b illustrate an example of an exterior appearance of a wearable device. The wearable device (101) of Figures 19a and 19b may be an example of the wearable device (101) of Figure 1. According to one embodiment, an example of an exterior appearance of a first side (1910) of a housing of a wearable device (101) is illustrated in Figure 19a, and an example of an exterior appearance of a second side (1920) opposite to the first side (1910) may be illustrated in Figure 19b.

[0236] Referring to FIG. 19A, according to one embodiment, a first surface (1910) of a wearable device (101) may have a form attachable to a body part of a user (e.g., the face of the user). Although not shown, the wearable device (101) may further include a strap for fixing to a body part of a user, and / or one or more temples (e.g., the first temple (1804) and / or the second temple (1805) of FIGS. 18A and 18B). A first display (1850-1) for outputting an image to a left eye among the user's two eyes, and a second display (1850-2) for outputting an image to a right eye among the two eyes, may be disposed on the first surface (1910). The wearable device (101) may be formed on the first surface (1910) and may further include a rubber or silicone packing to prevent interference by light (e.g., ambient light) different from the light emitted from the first display (1850-1) and the second display (1850-2).

[0237] According to one embodiment, the wearable device (101) may include cameras (1860-1) for photographing and / or tracking both eyes of the user adjacent to each of the first display (1850-1) and the second display (1850-2). The cameras (1860-1) may be referred to as the gaze tracking camera (1860-1) of FIG. 18B. According to one embodiment, the wearable device (101) may include cameras (1860-5, 1860-6) for photographing and / or recognizing the face of the user. The cameras (1860-5, 1860-6) may be referred to as FT cameras. The wearable device (101) may control an avatar representing the user in a virtual space based on the motion of the user's face identified using the cameras (1860-5, 1860-6). For example, the wearable device (101) may change the texture and / or shape of a portion of an avatar (e.g., a portion of an avatar representing a human face) using information obtained by cameras (1860-5, 1860-6) (e.g., FT cameras) and representing a facial expression of a user wearing the wearable device (101).

[0238] Referring to FIG. 19b, on a second surface (1920) opposite to the first surface (1910) of FIG. 19a, a camera (e.g., cameras (1860-7, 1860-8, 1860-9, 1860-10, 1860-11, 1860-12)) and / or a sensor (e.g., a depth sensor (1930)) for obtaining information related to the external environment of the wearable device (101) may be disposed. For example, the cameras (1860-7, 1860-8, 1860-9, 1860-10) may be disposed on the second surface (1920) for recognizing external objects. Cameras (1860-7, 1860-8, 1860-9, 1860-10) may be referenced to the motion recognition cameras (1860-2, 1860-3) of FIG. 18b.

[0239] For example, using cameras (1860-11, 1860-12), the wearable device (101) can obtain images and / or videos to be transmitted to each of the user's eyes. The camera (1860-11) can be positioned on the second face (1920) of the wearable device (101) to obtain an image to be displayed through the second display (1850-2) corresponding to the right eye among the two eyes. The camera (1860-12) can be positioned on the second face (1920) of the wearable device (101) to obtain an image to be displayed through the first display (1850-1) corresponding to the left eye among the two eyes. The cameras (1860-11, 1860-12) can be referred to as the shooting camera (1860-4) of FIG. 18B.

[0240] According to one embodiment, the wearable device (101) may include a depth sensor (1930) disposed on the second face (1920) to identify a distance between the wearable device (101) and an external object. Using the depth sensor (1930), the wearable device (101) may obtain spatial information (e.g., a depth map) for at least a portion of the FoV of a user wearing the wearable device (101). Although not shown, a microphone may be disposed on the second face (1920) of the wearable device (101) to obtain a sound output from an external object. The number of microphones may be one or more, depending on the embodiment.

[0241] In embodiments, an electronic device (101) is provided. The electronic device (101) may include a pressure sensor (210) including a sensing element (310) and a waterproof member (330) for protecting the sensing element (310), an inertial sensor (230), a processor (120), and a memory storing instructions. The instructions, when executed by the processor (120), may cause the electronic device (101) to determine direction information of the pressure sensor (210) from sensing data of the inertial sensor (230), determine a correction value according to the direction information of the pressure sensor (210) based on pressure offset data for the sensing element (310) in each of the designated directions of the pressure sensor (210), and provide pressure information using the pressure data of the pressure sensor (210) and the correction value.

[0242] For example, the pressure sensor (210) may include a housing, a substrate, and an application specific integrated circuit (ASIC) for outputting a sensing result of the sensing element (310). The sensing element (310) may include a MEMS (Micro Electro Mechanical Systems) sensor. The waterproof member (330) may include a gel arranged to cover the sensing element (310) and the ASIC in a space within the housing. Pressure offset data for the sensing element (310) may be stored in the ASIC.

[0243] For example, each of the above-mentioned directions may represent a direction in which the pressure-sensitive surface of the sensing element (310) faces. Pressure offset data for the sensing element (310) may represent a difference between a pressure value measured by the sensing element (310) in the corresponding direction and a reference pressure value.

[0244] For example, the specified directions may include a first direction in which the pressure-sensitive surface and the ground face the same direction, a second direction in which the pressure-sensitive surface faces substantially perpendicular to the ground, and a third direction in which the pressure-sensitive surface faces opposite directions to the ground.

[0245] For example, the instructions, when executed by the processor (120), may cause the electronic device (101) to obtain pressure offset data for the sensing element (310) in each of the designated directions of the pressure sensor (210) from the pressure sensor (210), determine an operation method between the direction of the pressure sensor (210) and a pressure correction value using the pressure offset data, and determine the correction value according to the direction information of the pressure sensor (210) using the operation method.

[0246] For example, the above calculation method may include a polynomial representing the pressure compensation value according to the direction of the pressure sensor (210). The coefficients of the polynomial may be obtained according to the pressure offset data for the sensing element (310) in each of the specified directions.

[0247] For example, the instructions, when executed by the processor (120), may cause the electronic device (101) to determine direction information of the inertial sensor (230) from sensing data of the inertial sensor (230), and to determine direction information of the barometric sensor (210) based on an angular difference between the inertial sensor (230) and the barometric sensor (210).

[0248] For example, the instructions, when executed by the processor (120), may cause the electronic device (101) to determine whether an acceleration dispersion of the electronic device (101) obtained from the sensing data is less than a threshold value, and if the acceleration dispersion of the electronic device (101) is greater than or equal to the threshold value, determine direction information of the inertial sensor (230) through the sensing data, and if the acceleration dispersion of the electronic device (101) is greater than or equal to the threshold value, determine direction information of the inertial sensor (230) through previous sensing data of the inertial sensor (230) and rotation information of the electronic device (101). The previous sensing data may have an acceleration dispersion less than or equal to the threshold value.

[0249] For example, the instructions, when executed by the processor (120), may cause the electronic device (101) to filter direction information of the inertial sensor (230) and determine direction information of the pressure sensor (210) based on the filtered direction information and the angular difference between the inertial sensor (230) and the pressure sensor (210).

[0250] For example, the angular difference between the inertial sensor (230) and the barometric pressure sensor (210) may represent the angular difference between the surface on which the inertial sensor (230) is placed and the surface on which the barometric pressure sensor (210) is placed. The angular difference may be obtained from the barometric pressure sensor (210) or by a specified user input.

[0251] For example, the electronic device (101) may further include a display. The pressure information may be displayed through the display.

[0252] For example, the inertial sensor (230) may include a 3-axis acceleration sensor or a 6-axis gyro acceleration sensor.

[0253] For example, the electronic device (101) may include a wearable device for wearing on a part of the user's body. The sensing data of the inertial sensor (230) may include a rotation value in the axial direction from one side of the part of the body to the other side opposite to the one side.

[0254] For example, the wearable device may be a head mount display (HMD) device to be worn on the user's head, a watch-type device to be worn on the user's wrist, or a ring-type device to be worn on the user's finger.

[0255] For example, the instructions, when executed by the processor (120), may cause the electronic device (101) to determine whether a specified application is running, and if the specified application is not running, to provide measured pressure information using the pressure data measured through the pressure sensor (210), and if the specified application is running, to provide the pressure information using the pressure data and the correction value.

[0256] In embodiments, an electronic device (101) is provided. The electronic device (101) may include a display, a pressure sensor (210) including a sensing element (310) and a waterproof member (330) for protecting the sensing element (310), an inertial sensor (230), a processor (120), and a memory storing instructions. The instructions, when executed by the processor (120), may cause the electronic device (101) to display first pressure information through the display via a first correction value according to a first direction when the pressure sensor (210) faces a first direction at a specified height, and to display second pressure information through the display via a second correction value according to the second direction when the pressure sensor (210) faces a second direction at the specified height. An angle formed by the second direction and a gravity direction may be smaller than an angle formed by the first direction and the gravity direction. The second correction value may indicate a pressure magnitude greater than the first correction value. For example, the first pressure data measured when the pressure sensor (210) faces the first direction at the specified height may be smaller than the second pressure data measured when the pressure sensor (210) faces the second direction at the specified height.

[0257] For example, the difference between the first pressure information and the second pressure information may be smaller than the difference between the first correction value and the second correction value.

[0258] For example, the first correction value and the second correction value may be determined according to a designated calculation method. The designated calculation method may be determined based on pressure offset data for the sensing element (310) in each of the designated directions of the pressure sensor (210). The pressure offset data for the sensing element (310) may be stored in the pressure sensor (210).

[0259] In embodiments, a non-transitory computer-readable recording medium is provided. The non-transitory computer-readable recording medium can store instructions. The instructions, when executed by a processor (120), can cause the electronic device (101) to: determine direction information of a barometric sensor (210) of the electronic device (101) from sensing data of an inertial sensor (230) of the electronic device (101), determine a correction value according to the direction information of the barometric sensor (210) based on pressure offset data for a sensing element (310) of the barometric sensor (210) in each of the designated directions of the barometric sensor (210), and provide pressure information using the pressure data of the barometric sensor (210) and the correction value.

[0260] In embodiments, a method performed by an electronic device (101) is provided. The method may include an operation of determining direction information of a barometric pressure sensor (210) of the electronic device (101) from sensing data of an inertial sensor (230) of the electronic device (101). The method may include an operation of determining a correction value according to the direction information of the barometric pressure sensor (210) based on pressure offset data for a sensing element (310) of the barometric pressure sensor (210) in each of the designated directions of the barometric pressure sensor (210). The method may include an operation of providing pressure information using the pressure data of the barometric pressure sensor (210) and the correction value. The barometric pressure sensor (210) may include a waterproof member (330) for protecting the sensing element (310).

[0261] In embodiments, a non-transitory computer-readable recording medium is provided. The non-transitory computer-readable recording medium can store instructions. The instructions, when executed by a processor, can cause an electronic device to display first pressure information through a display of the electronic device through a first correction value according to a first direction when a pressure sensor of the electronic device is oriented in a first direction at a specified height, and to display second pressure information through the display through a second correction value according to the second direction when the pressure sensor is oriented in a second direction at the specified height. An angle formed by the second direction and a direction of gravity can be smaller than an angle between the first direction and the direction of gravity. The second correction value can indicate a pressure magnitude greater than the first correction value.

[0262] In embodiments, a method performed by an electronic device is provided. The method may include: displaying first pressure information through a display of the electronic device through a first correction value according to a first direction when a pressure sensor of the electronic device is oriented in a first direction at a specified height; and displaying second pressure information through the display through a second correction value according to a second direction when the pressure sensor is oriented in a second direction at the specified height. An angle formed between the second direction and a gravity direction may be smaller than an angle between the first direction and the gravity direction. The second correction value may indicate a pressure magnitude greater than the first correction value.

[0263] The electronic device (101) according to embodiments of the present disclosure reflects a pressure compensation value corresponding to the direction of the pressure detection surface of the sensing element (310) of the atmospheric pressure sensor (210) to actually measured pressure data, thereby enabling more accurate measurement of atmospheric pressure (or water pressure). By identifying the direction of the atmospheric pressure sensor (210), which varies depending on the attitude of the electronic device (101), and applying a pressure offset corresponding to the direction, the problem of measurement distortion caused by the waterproof member (330) can be resolved. The user of the electronic device (101) can obtain more accurate information due to accurate measurement of altitude (or water depth), and can receive services related to height without error.
