The secondary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0025] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)).

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling the device. In one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of a force generated by the touch.

[0031] The audio module (170) can convert sound into an electrical signal, or vice versa, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150), output sound through the sound output module (155), or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphone) directly or wirelessly connected to the electronic device (101).

[0032] The sensor module (176) can detect the operating status (e.g., power or temperature) of the electronic device (101) or the external environmental status (e.g., user status) and generate an electrical signal or data value corresponding to the detected status. According to one embodiment, the sensor module (176) can include, for example, a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an IR (infrared) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

[0037] The power management module (188) can manage power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented, for example, as at least a part of a power management integrated circuit (PMIC).

[0038] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0039] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0040] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0041] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas by, for example, the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0042] According to various embodiments, the antenna module (197) may form a mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high frequency band.

[0043] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0044] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0045] Electronic devices according to the various embodiments disclosed in this document may take various forms. Electronic devices may include, for example, portable communication devices (e.g., smartphones), computer devices, portable multimedia devices, portable medical devices, cameras, wearable devices, or home appliances. Electronic devices according to the embodiments of this document are not limited to the aforementioned devices.

[0046] Figure 2 is a block diagram illustrating the configuration of a wearable device according to an embodiment of the present document.

[0047] Referring to FIG. 2, a wearable device (101) may include an input interface (150), a display (160), a sensor (176), and a processor (120).

[0048] The input interface (150) (e.g., the input module (150) of FIG. 1) can receive control commands from a user. For example, the input interface (150) can include a bezel, a stem (crown), a button, a jog dial, and / or a touch screen. As an example, if the input interface (150) is a bezel, a stem, and / or a jog dial, the processor (120) can perform a corresponding operation based on a signal according to the rotation of the input interface (150). Alternatively, if the input interface (150) is a button and / or a touch screen, the processor (120) can perform a corresponding operation based on a signal according to the touching and / or pressing of the input interface (150). In addition, the input interface (150) can receive information related to the wearing position of the wearable device (101) (e.g., the electronic device (101) of FIG. 1) from the user. For example, information related to the wearing position of the wearable device (101) may be information on whether it is worn on the user's left arm or right arm. The processor (120) may determine the axis of the second sensor (1762) based on the information related to the wearing position. The input interface (150) may be referred to as an input device, an input unit, an input module, or the like.

[0049] The display (160) (e.g., the display module (160) of FIG. 1) can output data processed by the processor (120) as an image. For example, the display (160) can output a user interface (UI) corresponding to a user input or change the displayed UI to another UI. Alternatively, the display (160) can display an app that is executed according to the user input. For example, the display (160) can be implemented as an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diode), and / or a touch screen. If the display (160) is implemented as a touch screen, the wearable device (101) can also receive control commands through the touch screen.

[0050] A sensor (176) (e.g., a sensor module (176) of FIG. 1) may include a first sensor (1761) and a second sensor (1762). The first sensor (1761) may detect whether the wearable device is being worn by a user. For example, the first sensor (1761) may be a wearing detection sensor and may include a photoplethysmogram (PPG) sensor, an electrocardiogram (ECG) sensor, a skin sensor, and / or an SpO2 (blood oxygen saturation) sensor. The second sensor (1762) may detect inertial information of the wearable device (101). For example, the second sensor (1762) may be an inertial sensor and may include an acceleration sensor, a gravity sensor, a gyro sensor, and / or a geomagnetic sensor.

[0051] The processor (120) (e.g., the processor (120) of FIG. 1) can control each component of the wearable device (101). The wearable device (101) can include one or more processors (120).

[0052] The processor (120) can determine whether the wearable device (101) is worn based on a signal (e.g., wearing information) detected by the first sensor (1761). If the processor (120) determines that the user is wearing the wearable device (101), it can determine whether the direction of the display (160) of the wearable device (101) is within or outside the user's field of vision.

[0053] The processor (120) can identify the direction and angle at which the display (16) faces based on a signal (e.g., inertial information) detected through the second sensor (1762). Since the wearable device (101) is worn on a part of the user's body, the inertial information detected according to the user's movement may include noise. Therefore, the processor (120) can perform a preprocessing process of low-pass filtering the detected inertial information. The processor (120) can determine the wearing point of the wearable device (101) based on the user's input. The processor (120) can determine the axis of the second sensor (1762) based on the determined wearing point. For example, if the user wears the wearable device (101) on the left arm, the processor (120) can determine the axis of the second sensor (1762) as the initially set axis. Alternatively, if the user wears the wearable device (101) on the right arm, the processor (120) may determine the axis of the second sensor (1762) to be symmetrical with respect to the axis initially set with respect to the user. The second sensor (1762) may detect inertial information of the second sensor (1762) based on the determined axis. The processor (120) may determine the vertical angle and size information of the display (160) (or, the wearable device (101)) based on the determined axis of the second sensor (1762) and inertial information to identify the direction and angle at which the display (160) faces. For example, the processor (120) may determine that one horizontal axis is tilted at 45 degrees based on the inertial information detected with respect to the axis of the second sensor (1762). Alternatively, the processor (120) may determine that one horizontal axis is tilted at -30 degrees.

[0054] If the identified direction and angle are outside the preset range, the processor (120) may determine that the direction in which the display (160) is facing is outside the user's field of vision. For example, the preset range may be set such that the inclination of one horizontal axis is between -60 degrees and 0 degrees. The preset range may be the user's field of vision. If the direction in which the display (160) is facing is within the preset range, the display (160) may be within the user's field of vision. Alternatively, if the direction in which the display (160) is facing is outside the preset range, the display (160) may be outside the user's field of vision. For example, if one horizontal axis of the detected inertial information is tilted by 45 degrees, the detected inertial information may be outside the preset range. Therefore, the processor (120) may determine that the direction in which the display (160) is facing is outside the user's field of vision. Alternatively, if one of the horizontal axes of the detected inertial information is tilted by -30 degrees, the detected inertial information may fall within a preset range. Accordingly, the processor (120) may determine that the direction in which the display (160) is facing is within the user's field of vision.

[0055] If the processor (120) determines that the direction of the display (160) is outside the user's field of vision, it may change the input judgment threshold of the input interface (150) from the set first threshold to a second threshold and set it. The input judgment threshold may be the minimum value associated with an input that the processor (120) determines to be a normal input. In addition, the second threshold may be a value greater than the first threshold.

[0056] For example, the input interface (150) may include a bezel, a crown, and / or a jog dial. In this case, the input determination threshold may be an angle. Accordingly, the first threshold may be a preset first angle, and the second threshold may be a preset second angle. As an example, the first threshold may be 30 degrees, and the second threshold may be 45 degrees. If the input determination threshold is the first threshold (e.g., 30 degrees) and the input interface (150) rotates by more than 30 degrees, the processor (120) may determine that a user command has been input and perform an operation corresponding to the input command. If the processor (120) determines that the direction of the display (160) is outside the user's field of vision, the processor (120) may change the input determination threshold to the second threshold (e.g., 45 degrees). When the input determination threshold is changed to the second threshold, the input interface (150) may rotate by 30 degrees. In this case, the processor (120) may determine that a normal command from the user has not been input and may ignore the rotation input to the input interface (150). Alternatively, the input interface (150) may rotate by more than 45 degrees. In this case, the processor (120) may determine that a normal command from the user has been input and may perform an operation corresponding to the rotation input to the input interface (150).

[0057] Alternatively, the input interface (150) may include a button and / or a touch screen. The button may be a physical button or a button in the form of a touch pad. In this case, the input determination threshold may be an input time, an input pressure, and / or a number of inputs. Accordingly, the first threshold may be a preset first input time, a first input pressure, and / or a first number of inputs, and the second threshold may be a preset second input time, a second input pressure, and / or a second number of inputs. If the input time, the input pressure, and / or the number of inputs input through the input interface (150) is greater than the preset input determination threshold, the processor (120) may perform an operation corresponding to the input.

[0058] For example, the corresponding action may include changing the mode and / or switching the screen of the wearable device (101). The wearable device (101) may include various modes. For example, the various modes may include a low-power mode and a normal mode. The low-power mode may include an a mode and a b mode. For example, the a mode may be a sleep mode. In the a mode (e.g., sleep mode), the processor (120) may supply power only related to the minimum essential functions and turn off the power otherwise (e.g., display off). The b mode may be an always on display (AOD) mode. In the b mode (e.g., AOD mode), the processor (120) may drive the display (160) at low power to display limited information on the display. The normal mode may be a wake up mode. In the normal mode (e.g., wake up mode), the processor (120) may supply power related to all functions. In normal mode, the processor (120) supplies normal power to the display (160), so that all information can be displayed on the display (160).

[0059] In addition, the processor (120) can determine whether the user's arm wearing the wearable device (101) is lowered and / or moved based on the detected inertial information. For example, if the vertical axis of the display (160) is horizontal and there is no (or almost no) movement of the wearable device (101), the processor (120) can determine that the user's arm is lowered. Alternatively, the processor (120) can identify change information in the roll value and / or pitch value of the wearable device (101) from the detected inertial information. If the identified change information in the roll value and / or pitch value is greater than or equal to a preset cycle, the processor (120) can determine that the user's arm is moving while swinging. The user may not use the wearable device (101) while the arm is lowered or moving while swinging. Accordingly, the processor (120) can determine that the user's state of lowering the worn arm or moving the arm while swinging it is outside the user's field of vision. Accordingly, the processor (120) can change the input judgment threshold from the first threshold to the second threshold.

[0060] After the processor (120) changes the input judgment threshold to the second threshold, if the direction of the display (160) remains outside the user's field of vision, the processor (120) can maintain the input judgment threshold at the second threshold regardless of the change in the display mode. For example, after the input judgment threshold is changed to the second threshold, the processor (120) can change the mode of the display from mode a to mode b depending on an input equal to or greater than the second threshold. Even if the mode of the display is changed, if the direction of the display (160) remains outside the user's field of vision, the processor (120) can maintain the input judgment threshold at the second threshold. Accordingly, if the processor (120) receives an input less than the second threshold, the processor (120) can ignore the received input.

[0061] FIGS. 3A and 3B are diagrams illustrating the relationship between the position of a wearable device and the direction of a user's gaze according to various embodiments of the present document.

[0062] Referring to FIG. 3A, a user wearing a wearable device (101) and sitting is illustrated. For example, when the wearable device (101) is worn on the user's left arm (or left hand), the upper direction of the user's arm may be the x-axis, the direction of the user's body may be the y-axis, and the vertical direction may be the z-axis. As an example, when the wearable device (101) moves -70 degrees in the horizontal direction and -30 degrees in the vertical direction according to the movement of the left arm, the display (160) may be directed toward the user's body area (1). The wearable device (101) may determine that the display (160) is within the user's field of vision when the direction of the display (160) is directed toward the user's body area (1). When the wearable device (101) moves -10 degrees in the horizontal direction and 70 degrees in the vertical direction, the display (160) may be directed toward the user's front area (3a). The wearable device (101) can determine that the display (160) is outside the user's field of vision when the display (160) is oriented toward the user's front area (3a). Alternatively, the display (160) can be oriented toward the user's left area (3b) when the x-axis of the wearable device (101) moves 30 degrees in the horizontal direction and the y-axis moves 50 degrees in the vertical direction. The wearable device (101) can determine that the display (160) is outside the user's field of vision when the display (160) is oriented toward the user's left area (3b).

[0063] The wearable device (101) can be worn on the user's right arm (or right hand). The wearable device (101) can receive information from the user about the position (e.g., left or right) where the wearable device (101) is to be worn. When the wearable device (101) receives input from the user that the wearing position is the right arm, the wearable device (101) can determine the axis of a second sensor (e.g., an inertial sensor). When the wearable device (101) is worn on the left arm, the wearable device (101) can move the axis in a direction that is symmetrical with respect to the axis. For example, the wearable device (101) can move the axis such that the upper direction of the user's arm is the x' axis, the direction of the user's body is the y' axis, and the vertical direction is the z' axis. As an example, when the x-axis of the wearable device (101) moves -70 degrees in the horizontal direction and the y-axis moves -30 degrees in the vertical direction according to the movement of the right arm, the display (160) can be directed toward the user's body area (1). The wearable device (101) can determine that the display (160) is within the user's field of vision when the display (160) is directed toward the user's body area (1). Alternatively, when the x-axis of the wearable device (101) moves -10 degrees in the horizontal direction and the y-axis moves 70 degrees in the vertical direction, the display (160) can be directed toward the user's front area (3a). The wearable device (101) can determine that the display (160) is outside the user's field of vision when the display (160) is directed toward the user's front area (3a). When the x-axis of the wearable device (101) moves 30 degrees in the horizontal direction and the y-axis moves 50 degrees in the vertical direction, the display (160) can be directed toward the user's right area (3c). When the direction of the display (160) is directed toward the user's right area (3c), the wearable device (101) can determine that the display (160) is outside the user's field of vision.

[0064] Referring to FIG. 3B, a user is depicted with his / her arm lowered while wearing a wearable device (101). For example, if the z-axis (or z'-axis) of the display (160) of the wearable device (101) is horizontal and there is no (or almost no) movement of the wearable device (101), the wearable device (101) can determine that the user is lowering his / her arm. In addition, the wearable device (101) can determine that the user is outside the user's field of vision.

[0065] If the wearable device (101) determines that the direction of the display (160) is outside the user's field of vision, the input determination threshold may be changed from a first threshold to a second threshold. The second threshold may be a value greater than the first threshold. If the wearable device (101) determines that the direction is outside the user's field of vision, the wearable device (101) may receive an input with a larger threshold value and operate. Accordingly, when the user is not looking at the wearable device (101) (or not using it), the wearable device (101) may prevent malfunction due to an unintended input from the user.

[0066] FIG. 4 is a flowchart illustrating a process of changing an input judgment threshold based on the orientation of a wearable device according to one embodiment of the present document.

[0067] Referring to Figure 4, 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.

[0068] 410 to 470 may be understood to be performed in a processor (e.g., processor (120) of FIG. 2) of a wearable device (e.g., wearable device (101) of FIG. 2).

[0069] Referring to FIG. 4, the wearable device (101) can determine whether it is worn (410). For example, the wearable device (101) can determine whether it is worn using a first sensor (e.g., a wearing detection sensor) (1761). If the wearable device (101) determines that it is not worn (410-N), it can maintain an input determination threshold (470). The wearable device (101) can generally set the first threshold as the input determination threshold. Accordingly, the wearable device (101) can maintain the first threshold.

[0070] If the wearable device (101) determines that it is worn (410-Y), it can analyze inertial information (420). The inertial information may include acceleration information and may be acquired using a second sensor (e.g., an inertial sensor) (1762). For example, the wearable device (101) can analyze the inertial information using Equation (1).

[0071] ------ (Formula 1)

[0072] In Equation 1, magnitude is the size of acceleration, and acc x is the x-axis acceleration, acc y is the y-axis acceleration, acc z can be z-axis acceleration, and FOV (field of view) can be field of view.

[0073]

[0074] The wearable device (101) can identify the viewing angle and determine whether the wrist is lowered (430). If the wearable device (101) determines that the viewing angle of the display (160) (or the wearable device (101)) is horizontal to the ground, the wearable device (101) can determine that the wrist is lowered. If the wearable device (101) determines that the wrist is lowered (430-Y), the input determination threshold can be changed from the first threshold to the second threshold (460).

[0075] If the wearable device (101) determines that the wrist is not lowered (430-N), it can determine whether the display (160) is horizontal (or nearly horizontal) with the ground (440). If the display (160) is horizontal with the ground (440-Y), the wearable device (101) can maintain the input determination threshold value as the first threshold value. If the display (160) is not horizontal with the ground (440-N), the wearable device (101) can determine whether the display (160) is oriented toward the body (450). The wearable device (101) can determine whether the display (160) is oriented toward the body based on the identified viewing angle. If the display (160) is not oriented toward the body (450-N), the wearable device (101) can change the input determination threshold value to the second threshold value (460). Alternatively, if the display (160) is oriented toward the body (450-Y), the wearable device (101) can maintain the input judgment threshold as the first threshold (470).

[0076] FIG. 5 is a diagram illustrating a preprocessing process of sensing data according to one embodiment of the present document.

[0077] Referring to FIG. 5, the waveform of sensing data is illustrated. Since the wearable device (101) is worn by a user, the acquired inertial information may include noise. The wearable device (101) may perform a preprocessing process on the acquired inertial information using a low-pass filter. The preprocessed inertial information may have its high-pass waveform filtered. Accordingly, the wearable device (101) can acquire inertial information with noise removed.

[0078] FIG. 6 is a drawing illustrating a process for determining the direction of a wearable device according to one embodiment of the present document.

[0079] Referring to FIG. 6, a wearable device (101) whose field of view changes according to the movement of a worn arm is illustrated. The wearable device (101) can obtain inertial information using a second sensor (1762) and identify a field of view from the obtained inertial information. The wearable device (101) can include a setting value for a user's field of view range. For example, the wearable device (101) can set a field of view range of 10 to 60 degrees as the user's field of view range. The wearable device (101) can identify the field of view according to the movement of the worn arm. As an example, if the field of view is 30 degrees, it can be within the preset field of view range of the user. Accordingly, the wearable device (101) can determine that it is within the user's field of view range (1). In addition, the wearable device (101) can maintain an input determination threshold value as a first threshold value. Alternatively, if the field of view is -30 degrees, it may be outside the preset user field of view. Accordingly, the wearable device (101) may determine that it is outside the user's field of view (3). In addition, the wearable device (101) may change the input judgment threshold to a second threshold.

[0080] FIG. 7 is a flowchart illustrating a process of changing an input judgment threshold based on movement of a wearable device according to one embodiment of the present document, and FIG. 8 is a diagram illustrating movement data of a wearable device according to one embodiment of the present document.

[0081] Referring to Figures 7 and 8, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0082] 710 to 750 may be understood to be performed in a processor (e.g., processor (120) of FIG. 2) of a wearable device (e.g., wearable device (101) of FIG. 2).

[0083] Referring to FIG. 7, the wearable device (101) can determine whether it is worn (710). If the wearable device (101) determines that it is not worn (710-N), it can maintain the input determination threshold (750). Accordingly, the wearable device (101) can maintain the first threshold.

[0084] If the wearable device (101) determines that it is worn (710-Y), it can analyze inertial information (420). For example, the inertial information may include acceleration information, and the wearable device (101) can analyze the acceleration information and identify the field of view. In addition, the wearable device (101) can identify change information of a roll value and / or a pitch value. As illustrated in FIG. 8, if the user shakes his / her arm at a regular cycle, the roll value and / or the pitch value may also change at a regular cycle (5). The wearable device (101) can determine whether the arm is moving based on the change information of the roll value and / or the pitch value (730). If the wearable device (101) determines that the arm is moving (730-Y), it can change the input determination threshold from a first threshold value to a second threshold value (740). Alternatively, if the wearable device (101) determines that the arm is not moving (or is almost not moving) (730-N), it can maintain the input judgment threshold (750).

[0085] The wearable device (101) may include various input interfaces. In addition, the wearable device (101) may determine a user's input based on a maintained input judgment threshold (e.g., a first threshold) or a changed input judgment threshold (e.g., a second threshold).

[0086] FIGS. 9A and 9B are drawings illustrating a bezel according to various embodiments of the present document, and FIG. 10 is a drawing illustrating a signal detected in a bezel according to one embodiment of the present document.

[0087] Referring to FIGS. 9A and 9B , a wearable device (101) including various input interfaces is illustrated. For example, the wearable device (101) may include a rotatable bezel (13) on top of a main housing (11). The main housing (11) includes a magnetic sensor (210), and the bezel (13) may include one or more magnets (a, b, c, d, e, f, g, h) at regular intervals. For example, the magnetic sensor (210) may include a Hall sensor and / or a magneto-resistive (MR) sensor.

[0088] As the bezel (13) rotates, one or more magnets (a, b, c, d, e, f, g, h) included in the bezel (13) may also rotate. In addition, as the one or more magnets (a, b, c, d, e, f, g, h) rotate, the distance between the one or more magnets (a, b, c, d, e, f, g, h) and the magnetic sensor (210) may increase or decrease. The magnetic field-related information (e.g., magnetic force, magnetic resistance) detected by the magnetic sensor (210) may increase or decrease depending on the increase or decrease in the distance between the magnets.

[0089] Referring to FIG. 10, as an example, a change in magnetic force detected by a magnetic sensor is illustrated. As an example, if eight magnets are arranged at a uniform distance on the bezel (13), each of the plurality of magnets (a, b, c, d, e, f, g, h) may be arranged at 45-degree intervals. As the magnets rotate according to the rotation of the bezel (13), the magnetic field-related information detected by the magnetic sensor (210) may also increase or decrease at 45-degree intervals. The wearable device (101) may determine that when the magnetic field-related information is greater than a certain value, it is one input unit (or tick). For example, the certain value may be a value less than a peak value near a peak value of the magnetic field-related information. Therefore, the wearable device (101) may determine that each time the bezel (13) rotates 45 degrees, it is one input unit. For example, if the first threshold of the wearable device (101) is set to 45 degrees (or one input unit), the wearable device (101) can determine one input each time the bezel (13) rotates 45 degrees.

[0090] Additionally, the wearable device (101) may include a touch screen, a button (51), a crown (53), and / or a jog dial. If the input interface (150) is the crown (53) and / or the jog dial, the wearable device (101) may set the input determination threshold in degrees. For example, if the first threshold of the crown (53) is set to 30 degrees, the wearable device (101) may determine that each 30-degree rotation of the crown (53) is one input. Alternatively, if the input interface (150) is a touch screen and / or a button (51), the wearable device (101) may set the input determination threshold in terms of time, pressure, and / or number of times. For example, the first threshold of the touch screen and / or button (51) is set to 1 second, and the wearable device (101) can determine that one input occurs when the touch screen and / or button (51) is pressed (or touched) for more than 1 second. Alternatively, the first threshold of the touch screen and / or button (51) is set to 1 time, and the wearable device (101) can determine that one input occurs when the touch screen and / or button (51) is pressed once.

[0091] FIG. 11 is a drawing illustrating a change in the input judgment threshold of a bezel according to one embodiment of the present document.

[0092] Referring to FIG. 11, a bezel (13) with a changed input judgment threshold is illustrated. If the wearable device (101) determines that the display (160) is out of the user's field of vision, the input judgment threshold can be changed from a first threshold to a second threshold. For example, the first threshold (7) may be 45 degrees (or one input unit) and the second threshold (9) may be 90 degrees (or two input units). Accordingly, if the input judgment threshold is changed from the first threshold (7) to the second threshold (9), the wearable device (101) may determine that when the bezel (13) is rotated 90 degrees, it is one input. Alternatively, if the input interface (150) is a crown (51) and / or a jog dial, the wearable device (101) may similarly change the first angle, which is the first threshold (7), to the second angle, which is the second threshold (9). Accordingly, the wearable device (101) can determine that an input is received when the input interface (150) (e.g., crown, jog dial) rotates by a second angle or more.

[0093] FIG. 12a is a drawing illustrating an input judgment threshold of a button according to one embodiment of the present document, and FIGS. 12b, 12c, and 12d are drawings illustrating changes in the input judgment threshold of a button according to various embodiments of the present document.

[0094] Referring to Fig. 12a, an input determination threshold is illustrated when the input interface (150) is a button (51) and / or a touch screen. The input determination threshold illustrated in Fig. 12a may be a first threshold. For example, the first threshold may be set to a pressure of a1, a time of t1, and / or a number of times of 1. Accordingly, the wearable device (101) may determine that an input is made when the input interface (150) is pressed beyond the set first threshold.

[0095] FIG. 12b illustrates a second threshold value when the input judgment threshold value is pressure according to one embodiment of the present document.

[0096] Referring to FIG. 12B, the first threshold value may be a1, and the second threshold value may be a2. When the input judgment threshold value is changed to the second threshold value, the wearable device (101) may determine that an input is input when the input interface (150) (e.g., a button, a touch screen) is pressed with a pressure greater than a2.

[0097] FIG. 12c illustrates a second threshold when the input judgment threshold is time according to one embodiment of the present document.

[0098] Referring to FIG. 12C, the first threshold value may be t1, and the second threshold value may be t2. When the input judgment threshold value is changed to the second threshold value, the wearable device (101) may determine that an input has occurred when the input interface (150) (e.g., a button, a touch screen) is pressed for a time greater than t2.

[0099] FIG. 12d illustrates a second threshold value when the input judgment threshold value is a number according to one embodiment of the present document.

[0100] Referring to FIG. 12d, the first threshold value may be 1 time, and the second threshold value may be 3 times. When the input judgment threshold value is changed to the second threshold value, the wearable device (101) may determine that an input has occurred when the input interface (150) (e.g., button, touch screen) is pressed 3 times.

[0101] The wearable device (101) can set input judgment thresholds using a combination of pressure, time, and / or number of times. As an example, the wearable device (101) can set a first threshold as pressure a1, time t1, and once, and set a second threshold as pressure a2, time t2, and three times.

[0102] FIGS. 13a and 13b are diagrams illustrating the operation of a wearable device according to various embodiments of the present document.

[0103] Referring to FIGS. 13A and 13B , when the wearable device (101) receives an input exceeding a set input judgment threshold, it may perform a corresponding action. For example, the corresponding action may include changing the display mode and / or switching the screen. The display mode may include a low-power a mode (e.g., sleep mode), a low-power b mode (e.g., AOD mode), and a normal mode (e.g., wake-up mode).

[0104] Referring to FIG. 13A, the wearable device (101) may be in a low-power a mode. For example, the input determination threshold may be changed to a second threshold, and the second threshold may be 90 degrees. At this time, when the bezel (13) (or, the crown (35), the jog dial) is rotated 90 degrees, the wearable device (101) may change the display mode from the low-power a mode to the low-power b mode. Alternatively, the wearable device (101) may change from the low-power b mode to the normal mode. When the input interface (150) is a button and / or a touch screen, and the button and / or the touch screen is pressed more than the second threshold, the wearable device (101) may change the display mode.

[0105] Referring to FIG. 13B, when the bezel (13) (or the crown (35), the jog dial) is rotated while an image (e.g., UI) is displayed on the display (160), the wearable device (101) can change the image displayed on the display (160) to another image. As an example, the first threshold value may be 30 degrees, and the second threshold value may be 90. If the direction in which the display (160) is facing is within the user's field of vision, the wearable device (101) can change the image in response to the bezel rotating by 30 degrees. Alternatively, if the direction in which the display (160) is facing is outside the user's field of vision, the wearable device (101) can change the image in response to the bezel rotating by 90 degrees. If the input interface (150) is a button and / or a touch screen, and the button and / or the touch screen is pressed by more than the second threshold value, the wearable device (101) can change the displayed screen.

[0106] Fig. 14 is a flowchart illustrating a sensing information-based input control method according to one embodiment of the present document.

[0107] Referring to Figure 14, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0108] 1410 to 1440 may be understood to be performed in a processor (e.g., processor (120) of FIG. 2) of a wearable device (e.g., wearable device (101) of FIG. 2).

[0109] Referring to FIG. 14, when the wearable device (101) detects the wearing information of the wearable device (101), it can identify the direction and angle at which the display (160) faces based on the inertial information (1410). For example, the wearable device (101) can obtain the wearing information through the wearing detection sensor (1761). For example, the wearing detection sensor (1761) can include a PPG (Photoplethysmogram) sensor, an ECG (Electrocardiogram) sensor, a skin sensor, and / or an SpO2 (blood oxygen saturation) sensor. In addition, the wearable device (101) can obtain the inertial information through the inertial sensor (1762). For example, the inertial sensor (1762) can include an acceleration sensor, a gravity sensor, a gyro sensor, and / or a geomagnetic sensor. The inertial information can include acceleration information. Since inertial information may contain noise, the wearable device (101) may perform a preprocessing step of low-pass filtering the inertial information.

[0110] Additionally, the wearable device (101) can receive information related to the wearing position from the user. The wearable device (101) can determine the axis of the inertial sensor based on the information related to the wearing position. For example, if the axis when the wearable device (101) is worn on the user's left arm is the first axis, the axis when the wearable device (101) is worn on the user's right arm may be an axis moved in a direction symmetrical with respect to the first axis.

[0111] The wearable device (101) can identify the direction and angle at which the display (160) is facing by determining the axis of the inertial sensor, the vertical angle of the display (160) based on inertial information, and size information.

[0112] If the identified direction and angle are outside the preset range, the wearable device (101) may determine that the direction toward which the display (160) is facing is outside the user's field of vision (1420). For example, if the preset range is 10 to 60 degrees and the identified direction and angle are -30 degrees, the wearable device (101) may determine that the direction toward which the display (160) is facing is outside the user's field of vision.

[0113] If the wearable device (101) determines that the range is outside the user's field of vision, the input determination threshold of the input interface (150) can be changed from the first threshold to the second threshold (1430). In addition, if the vertical axis of the display (160) of the wearable device (101) is horizontal and there is no movement (or almost no movement) of the wearable device (101), the processor (120) can determine that the user is lowering the arm that is worn. Alternatively, the wearable device (101) can identify change information in the roll value and / or pitch value of the wearable device (101) from inertial information. If the identified change information in the roll value and / or pitch value is greater than or equal to a preset cycle, the wearable device (101) can determine that the user is moving while shaking the arm that is worn. The wearable device (101) can determine that the user is lowering the worn arm or moving while shaking the arm as being outside the user's field of vision.

[0114] In addition, if the wearable device (101) determines that the input judgment threshold value is changed to the second threshold value and the direction in which the display (160) is facing is outside the user's field of vision, the wearable device (101) can maintain the input judgment threshold value at the second threshold value even if the mode of the display (160) is changed.

[0115] The wearable device (101) can perform an operation corresponding to the input when a value greater than the input judgment threshold is input (1440). For example, the input interface (150) can include a bezel, a crown, and / or a jog dial. The input judgment threshold can be an angle, and the first threshold can be a preset first angle, and the second threshold can be a preset second angle. The wearable device (101) can perform an operation corresponding to the input when the angle input through the input interface (150) is greater than the preset input judgment threshold.

[0116] Alternatively, the input interface (150) may include a button and / or a touch screen. The input determination threshold may include an input time, an input pressure, and / or a number of inputs. The first threshold may include a preset first input time, a first input pressure, and / or a first number of inputs, and the second threshold may include a preset second input time, a second input pressure, and / or a second number of inputs. The wearable device (101) may perform an action corresponding to the input if the input time, the input pressure, and / or the number of inputs input through the input interface (150) is greater than the preset input determination threshold. For example, the action corresponding to the input may include changing the mode of the display (160) and / or switching the screen.

[0117] For example, a wearable device (101) may include an input interface (150), a first sensor (1761) for detecting wearing information of the wearable device (101), a second sensor for detecting inertial information of the wearable device (101), a display (160), and at least one processor (120). When the at least one processor (120) detects wearing information of the wearable device (101) through the first sensor (1761), the at least one processor (120) may identify a direction and angle toward which the display (160) faces based on inertial information detected through the second sensor (1762). When the identified direction and angle are outside a preset range, the at least one processor (120) may determine that the direction toward which the display (160) faces is outside a range of the user's field of vision. If the at least one processor (120) determines that the range is outside the user's field of vision, the input judgment threshold of the input interface (150) can be changed from the set first threshold to a second threshold greater than the first threshold. When a value greater than the input judgment threshold is input through the input interface (150), the at least one processor (120) can perform an operation corresponding to the input.

[0118] For example, the at least one processor (120) may receive information related to the wearing position of the wearable device (101) through the input interface (150), and determine the axis of the second sensor (1762) based on the information related to the input wearing position.

[0119] For example, the at least one processor (120) can identify the direction and angle at which the display (160) is facing by determining the axis of the determined second sensor (1762), the vertical angle of the display (160) based on the inertial information, and size information.

[0120] For example, the at least one processor (120) may identify change information of a roll value and a pitch value of the wearable device (101) based on the detected inertial information. If the identified change information of the roll value and pitch value is greater than or equal to a preset cycle, the at least one processor (120) may change the input determination threshold of the input interface (150) from the first threshold value to the second threshold value.

[0121] For example, the input interface (150) may include at least one of a bezel (13), a crown (53), and a jog dial. The first threshold value may be a preset first angle, and the second threshold value may be a preset second angle. If the angle input through the input interface (150) is greater than the preset input determination threshold value, the at least one processor (120) may perform an operation corresponding to the input.

[0122] For example, the wearable device (101) may further include a main housing (11) including a magnetic sensor (210). If the input interface (150) is a bezel (13), the bezel (13) may include magnets (a, b, c, d, e, f, g, h) arranged at preset intervals and may be arranged to rotate on the upper portion of the main housing. The magnetic sensor (210) may detect information on a change in a magnetic field based on a distance from magnets (a, b, c, d, e, f, g, h) that move in response to an input for rotating the bezel (13). The at least one processor (120) may identify the input angle based on the information on the change in the magnetic field.

[0123] For example, the input interface (150) may include at least one of a button (51) and a touch screen. The first threshold may include at least one of a preset first input time, a first input pressure, and a first number of inputs, and the second threshold may include at least one of a preset second input time, a second input pressure, and a second number of inputs. If at least one of the input time, the input pressure, and the number of inputs input through the input interface (150) is greater than the preset input determination threshold, the at least one processor (120) may perform an operation corresponding to the input.

[0124] For example, if the at least one processor (120) determines that the input judgment threshold value is changed to a second threshold value and the direction in which the display (160) is facing is outside the user's field of vision, the input judgment threshold value can be maintained at the second threshold value even if the mode of the display (160) is changed.

[0125] For example, the at least one processor (120) may low-pass filter the sensed inertial information.

[0126] For example, a sensing information-based input control method of a wearable device (101) can detect wearing information of the wearable device (101) through a first sensor (1761), identify a direction and angle toward which the display (160) is facing based on inertial information detected through a second sensor (1762). If the identified direction and angle are outside a preset range, the control method can determine that the direction toward which the display (160) is facing is outside the user's field of vision. If the control method determines that the direction is outside the user's field of vision, the input determination threshold of the input interface (150) can be changed from a preset first threshold to a second threshold greater than the first threshold. When a value greater than the input determination threshold is input, the control method can perform an operation corresponding to the input.

[0127] For example, the control method may receive information related to the wearing position of the wearable device (101). The control method may determine the axis of the second sensor (1762) based on the information related to the input wearing position.

[0128] For example, the operation of identifying the direction and angle toward which the display (160) is facing can identify the direction and angle toward which the display (160) is facing by determining the axis of the determined second sensor (1762), the vertical angle of the display (160) based on the inertial information, and the size information.

[0129] For example, the control method can identify change information of the roll value and pitch value of the wearable device (101) based on the detected inertial information. If the identified change information of the roll value and pitch value is greater than or equal to a preset cycle, the control method can change the input judgment threshold of the input interface (150) from the first threshold value to the second threshold value.

[0130] For example, the input interface (150) may include at least one of a bezel (13), a crown (53), and a jog dial. The first threshold value may be a preset first angle, and the second threshold value may be a preset second angle. An operation corresponding to the input may be performed when an angle input through the input interface (150) is greater than the preset input determination threshold value.

[0131] For example, an operation that performs an action corresponding to the input may detect information about changes in a magnetic field based on the distance from a magnet (a, b, c, d, e, f, g, h) that moves in response to an input that rotates the bezel (13). An operation that performs an action corresponding to the input may identify an angle that is input based on information about changes in the magnetic field.

[0132] For example, the input interface (150) may include at least one of a button (51) and a touch screen. The first threshold may include at least one of a preset first input time, a first input pressure, and a first input count, and the second threshold may include at least one of a preset second input time, a second input pressure, and a second input count. An operation corresponding to the input may be performed if at least one of the input time, the input pressure, and the input count input through the input interface (150) is greater than the preset input determination threshold, thereby performing the operation corresponding to the input.

[0133] For example, if the control method determines that the input judgment threshold value is changed to a second threshold value and the direction toward which the display (160) is facing is outside the user's field of vision, the control method can maintain the input judgment threshold value at the second threshold value even if the mode of the display (160) is changed.

[0134] For example, the control method may further include an operation of low-pass filtering the sensed inertial information.

[0135] For example, a non-transitory computer-readable storage medium having recorded thereon a program for performing a sensing information-based input control method of a wearable device (101) may, when wearing information of the wearable device (101) is detected through a first sensor (1761), perform an operation of identifying a direction and angle toward which the display (160) is facing based on inertial information detected through a second sensor (1762). If the identified direction and angle are outside a preset range, the non-transitory computer-readable storage medium may perform an operation of determining that the direction toward which the display (160) is facing is outside a range of the user's field of vision. If the non-transitory computer-readable storage medium determines that the range is outside the range of the user's field of vision, the non-transitory computer-readable storage medium may perform an operation of changing and setting an input determination threshold of the input interface (150) from a preset first threshold to a second threshold greater than the first threshold. If a value greater than the input determination threshold is input, the non-transitory computer-readable storage medium may perform an operation of performing an operation corresponding to the input.

[0136] For example, the non-transitory computer-readable storage medium may perform an operation of identifying change information in a roll value and a pitch value of the wearable device (101) based on the sensed inertial information. If the identified change information in the roll value and pitch value is greater than or equal to a preset cycle, the non-transitory computer-readable storage medium may perform an operation of changing the input determination threshold value of the input interface (150) from the first threshold value to the second threshold value.
