A sensor controller (250a) can control a plurality of light emitting units (250b) and a plurality of light receiving units (250c).

[0082] According to an embodiment, the first sensor (250) may be called a biometric sensor, and for convenience of explanation, it will be collectively referred to as the first sensor (250) hereinafter.

[0083] The second sensor (246) according to the embodiment can detect a touch signal of a user touching the wearable device (200). The second sensor (246) can be formed using at least one of a pressure type, an electrostatic type, an optical type, or an ultrasonic type, for example. The second sensor (246) according to the embodiment can also include a fingerprint sensor.

[0084] In some embodiments, the second sensor (246) may be omitted.

[0085] According to an embodiment, the second sensor (246) may be called a touch sensor, and for convenience of explanation, it will be collectively referred to as the second sensor (246) hereinafter.

[0086] The third sensor (247) according to an embodiment can obtain movement information of the wearable device (200). For example, the third sensor (247) can detect motion, gesture, impact, posture, and / or activity (e.g., sedentary, moving, sports). The third sensor (247) may be formed as a 3-axis accelerometer, but is not limited thereto, and may be formed as a 6-axis sensor including an accelerometer and a gyroscope. Depending on the embodiment, the third sensor (247) may be called an inertial sensor, an acceleration sensor, etc., but for the convenience of explanation, it will be collectively referred to as the third sensor (247) hereinafter.

[0087] A temperature sensor (248) according to an embodiment can measure the body temperature of a user or the temperature of a component (e.g., an electronic component) included in a wearable device (200). The temperature sensor (248) can be formed in a contact or non-contact manner and may vary depending on the design. The wearable device (200) can record temperature information recorded through the temperature sensor (248) in a memory (242), or measure the body temperature of the user under the control of a processor (241), and utilize it to estimate skin temperature or estimate situational awareness.

[0088] A PMIC (249) according to an embodiment can manage power delivered from a battery (230) to each component of a wearable device (200).

[0089] The memory (242) according to the embodiment may store various instructions that may be performed by the processor (241). Such instructions may include arithmetic and logical operations, data movement, or control commands such as input / output that may be recognized by the processor (241).

The calculation and data processing functions that the processor (241) may implement on the wearable device (200) are not limited, but may process various operations according to the present disclosure in conjunction with the electronic device (100).

[0091]

[0092] FIG. 7 is a flowchart for explaining a method for controlling a wearable device according to an embodiment of the present disclosure.

[0093] Referring to FIG. 7, according to an embodiment, a wearable device (200) can identify whether a user is wearing the wearable device through a first sensor (250).

[0094] For example, in operation S710, the wearable device (200) can detect whether a first finger is inserted into the wearable device through the first sensor (250).

[0095] For example, the first sensor (250) includes a PPG sensor or an optical sensor, and the first sensor (250) can sense an object.

[0096] For example, when a pulse wave is detected based on the first sensing data of the first sensor (250), the wearable device (200) can identify the object detected by the first sensor (250) as the user's finger.

[0097] However, the present invention is not limited thereto, and when an electrocardiogram (ECG) is detected based on the first sensing data of the first sensor (250), the wearable device (200) can identify the object detected by the first sensor (250) as the user's finger. That is, the wearable device (200) can identify that the user's finger is inserted into the wearable device (200). Hereinafter, for the convenience of explanation, the finger inserted into the wearable device (200) will be collectively referred to as the first finger.

[0098] According to an embodiment, in operations S710-Y and S720, when insertion of a first finger into the wearable device (200) is detected through the first sensor (250), the wearable device (200) may activate the second sensor (246) and the third sensor (247).

[0099] For example, the wearable device (200) can control the PMIC (249) so that the battery (230) supplies power to each of the second sensor (246) and the third sensor (247). However, this is an example and is not limited thereto.

[0100] For example, the wearable device (200) may control the PMIC (249) so that the battery (230) supplies power to each of the first sensor (250), the second sensor (246), and the third sensor (247) regardless of whether the first finger is inserted in the normal mode, and may control the PMIC (249) so that the battery (230) supplies power to only the first sensor (250) before the first finger is inserted, and may control the PMIC (249) so that the battery (230) supplies power to each of the first sensor (250), the second sensor (246), and the third sensor (247) after the first finger is inserted.

[0101] According to an embodiment, in operation S730, the wearable device (200) can identify an interaction with the wearable device (200) through at least one of the second sensor (246) or the third sensor (247).

[0102] For example, in operation S730, when a contact of a finger on the outer surface of the wearable device (200) is detected through the second sensor (246), the wearable device (200) can identify an interaction with the wearable device (200) through at least one of the second sensor (246) or the third sensor (247).

[0103] For example, in operation S730, the wearable device (200) can detect a touch motion on the outer surface of the wearable device (200) through the second sensor (246) as an interaction with the wearable device (200).

[0104] For example, in operation S730, when a finger contact is detected on the outer surface of the wearable device (200) through the second sensor (246) and a change in acceleration is detected through the third sensor (247), the wearable device (200) can identify an operation of rotating the wearable device (200) as an interaction with the wearable device (200).

[0105] For example, when the outer surface of the wearable device (200) inserted into the first finger is held by at least one finger and the wearable device (200) is rotated, the wearable device (200) can detect the contact of at least one finger with the outer surface based on the second sensing data of the second sensor (246), and can detect a change in acceleration according to the rotation of the wearable device (200) based on the third sensing data of the third sensor (247).

[0106] According to an embodiment, in operation S740, the wearable device (200) can identify a control command corresponding to the interaction.

[0107] For example, in operation S740, when a touch action on the outer surface of the wearable device (200) is identified, the wearable device (200) can identify a control command corresponding to the touch action.

[0108] For example, in operation S740, when an operation of rotating the wearable device (200) is identified, the wearable device (200) can identify a control command corresponding to the operation of rotating the wearable device (200).

[0109] According to an embodiment, in operation S750, the wearable device (200) can control the communication module (243) to transmit the identified control command to the electronic device.

[0110]

[0111] FIG. 8 is a flowchart illustrating a method for controlling an electronic device by identifying a rotation length according to an embodiment of the present disclosure.

[0112] Since operations S810 and S820 illustrated in FIG. 8 are identical to operations S710 and S720 illustrated in FIG. 7, duplicate descriptions will be omitted.

[0113] Referring to FIG. 8, in operation S830, the wearable device (200) can detect (or identify) whether a finger is in contact with the outer surface of the wearable device (200) based on the second sensing data of the second sensor (246).

[0114] According to an embodiment, the second sensor (246) is placed in the first housing (210) and may be formed in at least one of a pressure type, an electrostatic type, an optical type, or an ultrasonic type.

[0115] According to an embodiment, the second sensor (246) may obtain second sensing data indicating whether the user's finger is in contact with the outer surface when the user's finger is in contact with the outer surface. According to an embodiment, the wearable device (200) may detect (or identify) whether the user's finger is in contact with the outer surface based on the second sensing data.

[0116] Hereinafter, for convenience of explanation, the finger in contact with the outer surface is referred to as the second finger to distinguish it from the finger inserted into the wearable device (200) (i.e., the first finger).

[0117] According to an embodiment, in operation S830, the contact of the second finger on the outer surface is detected through the second sensor (246), and in operation S840, third sensing data including acceleration change can be obtained through the third sensor (247).

[0118] For example, the third sensor (247) may include an inertial sensor or an acceleration sensor that detects changes in acceleration. Depending on the embodiment, the third sensor (247) may obtain third sensing data by detecting changes in gravity (e.g., gravity of each of the left, right, front, and back, and up and down) along the X, Y, and Z axes, or may obtain third sensing data by detecting changes in gravity and angular velocity along the X, Y, and Z axes, respectively.

[0119] According to an embodiment, in operation S850, the wearable device (200) can identify a first interaction that rotates the wearable device (200) based on an acceleration change included in the third sensing data.

[0120] For example, the first interaction may include an action of rotating the wearable device (200) (identified in action S850) using at least one finger (identified in action S830) that is in contact with the outer surface of the wearable device (200) inserted into the first finger.

[0121] According to an embodiment, when the first interaction is identified in operation S860, the wearable device (200) can identify a rotation length according to the rotation of the wearable device (200).

[0122] For example, the third sensing data acquired through the third sensor (247) includes changes in gravity along each of the X, Y, and Z axes, and angular velocities (rad / s) along each of the X, Y, and Z axes, and the wearable device (200) can identify the rotational length (or rotational angle) of the wearable device (200) according to the first interaction (or while the first interaction is being identified) based on the third sensing data.

[0123] According to an embodiment, in operation S870, the wearable device (200) can identify a section to which the identified rotation length belongs among a plurality of sections.

[0124] According to an embodiment, in operation S880, the wearable device (200) may identify a control command corresponding to an identified section among a plurality of control commands. For example, the plurality of sections may include a first section and a second section, where the first section may correspond to a first control command and the second section may correspond to a second control command.

[0125] According to an embodiment, if the rotation length identified in operation S870 belongs to the first section, the wearable device (200) can identify the first control command corresponding to the first section in operation S880.

[0126] According to an embodiment, the wearable device (200) may transmit the identified control command to the electronic device (100). For example, if a first control command corresponding to the first section is identified in operation S880, the wearable device (200) may transmit the first control command to the electronic device (100) in operation S890, thereby controlling the electronic device (100).

[0127]

[0128] FIG. 9 is a drawing for explaining a plurality of sections according to an embodiment of the present disclosure.

[0129] For example, the plurality of sections may include a first section, a second section, and a third section. For example, the first section may include 1 cm to 3 cm, the second section may include 3 cm to 5 cm, and the third section may include 5 cm to 7 cm. The specific numbers are merely examples for convenience of explanation and are not intended to be limiting.

[0130] Depending on the embodiment, the plurality of sections may not include 0 cm to 1 cm. For example, the wearable device (200) may rotate due to the user's activity rather than the user's intention to control the electronic device (100) through the wearable device (200). In order to prevent the electronic device (100) from being controlled due to rotation of the wearable device (200) that is not intentional by the user, the wearable device (200) may not set a control command corresponding to a fine rotation (e.g., a rotation of 0 cm to 1 cm). However, this is an example for the convenience of explanation and is not limited thereto.

[0131] According to an embodiment, the wearable device (200) can identify a rotation length according to the rotation of the wearable device (200) in operation S860 of FIG. 8, and can identify one of a plurality of sections (e.g., a first section, a second section, and a third section) to which the identified rotation length belongs in operation S870.

[0132] For example, if the wearable device (200) identifies a rotation length of 1.5 cm based on the change in acceleration included in the third sensing data, the wearable device (200) can identify a first section among the plurality of sections, and if the rotation length is identified as 5.2 cm, the wearable device (200) can identify a third section among the plurality of sections.

[0133] According to an embodiment, the wearable device (200) may identify a first control command corresponding to the first section and transmit it to the electronic device (100) when the rotation length belongs to the first section, as described in operations S880 and S890 of FIG. 8, and may identify a second control command corresponding to the second section and transmit it to the electronic device (100) when the rotation length belongs to the second section.

[0134] According to an embodiment, the wearable device (200) may provide feedback so that the user can recognize the section to which the rotational length of the wearable device (200) belongs.

[0135] For example, the wearable device (200) can control the display (201) to emit a color corresponding to the section to which the current rotation length of the wearable device (200) belongs while the first interaction is identified, i.e., the operation of rotating the wearable device (200) using a second finger that is in contact with the outer surface of the wearable device (200) inserted into the first finger.

[0136] In Fig. 9, the display (201) is illustrated as an indicator such as an LED for convenience of explanation, but is not limited thereto and may be implemented as the display (201) illustrated in Fig. 3.

[0137] For example, if the current rotation length of the wearable device (200) belongs to the first section, the wearable device (200) can control the display (201) to emit a color corresponding to the first section, and if the current rotation length of the wearable device (200) belongs to the second section, the wearable device (200) can control the display (201) to emit a color corresponding to the second section.

[0138] According to an embodiment, the display (201) may be placed on the outer surface of the wearable device (200).

[0139] According to an embodiment, a user can identify which section of a plurality of sections the current rotation length of the wearable device (200) belongs to based on the color emitted by the display (201), and can stop the first interaction of rotating the wearable device (200) when the user wants to transmit a control command corresponding to the section to which the current rotation length belongs to the electronic device (100).

[0140] According to an embodiment, if the first interaction is not identified for a preset time or longer (or if the first interaction is interrupted for a preset time or longer), the wearable device (200) may transmit a control command corresponding to the section to which the current rotation length of the wearable device (200) belongs to the electronic device (100).

[0141] According to an embodiment, the wearable device (200) can identify a section to which a rotation length that is the sum of the first rotation length and the second rotation length belongs among a plurality of sections when a first rotation length is identified according to a first rotation of the wearable device (200) and a second rotation length is identified according to a second rotation of the wearable device (200) within a preset time.

[0142] For example, when the wearable device (200) rotates (first rotation) according to a first interaction and then rotates again (second rotation) according to the first interaction within a preset time, the wearable device (200) can identify a rotation length that is the sum of the first rotation length according to the first rotation and the second rotation length according to the second rotation, and can identify a section to which the identified rotation length belongs.

[0143] For example, if a rotation length that is the sum of the first rotation length and the second rotation length is included in the second section, the wearable device (200) can transmit a control command corresponding to the second section to the electronic device (100).

[0144]

[0145] FIG. 10 is a drawing for explaining feedback according to an embodiment of the present disclosure.

[0146] Referring to Case 1 of FIGS. 9 and 10, the wearable device (200) can identify a color corresponding to a section to which the current rotation length of the wearable device (200) belongs among a plurality of sections. The wearable device (200) can control the display to emit the identified color.

[0147] However, the present invention is not limited thereto, and referring to Case 2 of FIG. 10, the wearable device (200) may also control a haptic module provided in the wearable device (200) to provide feedback.

[0148] For example, the wearable device (200) can control the haptic module to vibrate once when the current rotation length of the wearable device (200) belongs to the first section, and can control the haptic module to vibrate twice when the current rotation length of the wearable device (200) belongs to the second section.

[0149] However, the present invention is not limited thereto, and the wearable device (200) may control the haptic module to vibrate whenever the section to which the current rotational length of the wearable device (200) belongs changes while the first interaction is identified. For example, the wearable device (200) may control the haptic module to vibrate when the section to which the rotational length of the wearable device (200) belongs changes from the first section to the second section according to the first interaction.

[0150] Referring to Case 3 of FIG. 10, the wearable device (200) may also control the communication module (243) to communicate with an external device (300) to provide feedback.

[0151] For example, if the current rotation length of the wearable device (200) falls within the first section, the wearable device (200) can control the communication module (243) to transmit information on a first control command corresponding to the first section to an external device (300). The external device (300) can output information on the first control command corresponding to the first section based on the received information.

[0152] For example, when the section to which the rotational length of the wearable device (200) belongs changes from the first section to the second section according to the first interaction, the wearable device (200) controls the communication module (243) to transmit information on a second control command corresponding to the second section to the external device (300), and the external device (300) can output information on the second control command corresponding to the second section based on the received information.

[0153] In Case 3 of Fig. 10, an embodiment is assumed in which an external device (300) outputs information about a control command corresponding to a section to which the current rotation length of the wearable device (200) belongs, but is not limited thereto.

[0154] For example, the wearable device (200) includes at least one speaker for providing auditory output information to the user, and the wearable device (200) can control at least one speaker provided in the wearable device (200) to output information about a control command corresponding to a section to which the current rotational length of the wearable device (200) belongs.

[0155] For example, the wearable device (200) may control the communication module (243) to transmit information about a control command corresponding to a section belonging to the current rotation length of the wearable device (200) to the electronic device (100). According to an embodiment, the electronic device (100) may transmit information about the control command to an external device (300) that is connected or can be connected to the electronic device (100) based on information about the control command received from the wearable device (200). According to an embodiment, the external device (300) may output information about the control command based on information about the control command received from the electronic device (100).

[0156]

[0157] FIG. 11 is a drawing for explaining control commands corresponding to each of a plurality of sections according to an embodiment of the present disclosure.

[0158] Referring to FIG. 11, an electronic device (100) communicating with a wearable device (200) can provide a user interface (UI) for setting control commands corresponding to each of a plurality of sections.

[0159] For example, the electronic device (100) can control the display (140) to display a user interface (UI) for setting control commands corresponding to each of a plurality of sections.

[0160] According to an embodiment, the electronic device (100) may set the length of each of the plurality of sections, a control command corresponding to each of the plurality of sections, and whether the control command corresponding to each of the plurality of sections is activated (e.g., On / Off) based on a user command for the UI.

[0161] According to an embodiment, the electronic device (100) may transmit information about a control command corresponding to each of a plurality of sections to the wearable device (200). According to an embodiment, the information about the control command corresponding to each of a plurality of sections may include the length of each of the plurality of sections, the control command corresponding to each of the plurality of sections, and whether the control command corresponding to each of the plurality of sections is activated (e.g., On / Off).

[0162] According to an embodiment, the wearable device (200) may identify a control command corresponding to a current rotation length of the wearable device (200) and transmit the control command to the electronic device (100) if the first interaction is not identified for a preset time or longer (or if the first interaction is interrupted for a preset time or longer) based on information about a control command corresponding to each of a plurality of sections.

[0163] According to an embodiment, when a control command is received from a wearable device (200), the electronic device (100) can control the electronic device (100) based on the control command.

[0164] However, the present invention is not limited thereto, and when a rotation length according to a first interaction with the wearable device (200) is received from the wearable device (200), the electronic device (100) may identify a section corresponding to the rotation length based on information about a control command corresponding to each of a plurality of sections, and may control the electronic device (100) by identifying a control command corresponding to the identified section.

[0165] For example, if the first interaction is not identified for a preset time or longer (or if the first interaction is interrupted for a preset time or longer), the wearable device (200) transmits the current rotation length of the wearable device (200) to the electronic device (100), and the electronic device (100) can identify a control command based on the received rotation length.

[0166]

[0167] FIG. 12 is a drawing for explaining a plurality of sections according to an embodiment of the present disclosure.

[0168] Although the above-described example has been described assuming a rotation length, referring to FIG. 12, the wearable device (200) can identify the rotation angle of the wearable device (200) according to the first interaction (or while the first interaction is being identified) based on the third sensing data.

[0169] According to an embodiment, the wearable device (200) can identify a section corresponding to a rotation angle of the wearable device (200) among a plurality of sections.

[0170] For example, the multiple sections may include a first section, a second section, and a third section. For example, the first section may include 0 to 40 degrees, the second section may include 40 to 80 degrees, and the third section may include 80 to 120 degrees. The specific numbers are examples for convenience of explanation and are not intended to be limiting.

[0171] Depending on the embodiment, the plurality of sections may not include 0 to 40 degrees. For example, the wearable device (200) may rotate due to the user's activity rather than the user's intention to control the electronic device (100) through the wearable device (200). In order to prevent the electronic device (100) from being controlled due to rotation of the wearable device (200) that is not intentional by the user, the wearable device (200) may not set a control command corresponding to a fine rotation (e.g., a rotation of 0 to 40 degrees). However, this is an example for convenience of explanation and is not limited thereto.

[0172]

[0173] Referring to Case 4 of FIG. 12 according to an embodiment, the wearable device (200) can control the display (201) to display a control command corresponding to a section to which the current rotation angle of the wearable device (200) belongs among a plurality of sections.

[0174] According to an embodiment, a user can identify a control command corresponding to a section to which the current rotation angle of the wearable device (200) belongs based on a control command displayed by the display (201), and, when the user wishes to transmit the control command to the electronic device (100), the user can stop the first interaction of rotating the wearable device (200).

[0175] According to an embodiment, if the first interaction is not identified for a preset time or longer (or, if the first interaction is interrupted for a preset time or longer), the wearable device (200) may transmit a control command corresponding to a section to which the current rotation angle of the wearable device (200) belongs (or, a control command currently being displayed by the display (201)) to the electronic device (100).

[0176]

[0177] FIG. 13 is a flowchart illustrating a method for controlling a wearable device by acquiring biometric information according to an embodiment of the present disclosure.

[0178] Since operation S1301 illustrated in FIG. 13 is identical to operation S810 illustrated in FIG. 8, duplicate description will be omitted.

[0179] According to the embodiment, in operation S1302, the wearable device (200) can obtain biometric information through the first sensor (250).

[0180] For example, based on the first sensing data acquired through the first sensor (250), the wearable device (200) can identify a heart rate and acquire heart rate variability (HRV) as biometric information. For example, heart rate variability may include the length of time that changes between consecutive heartbeats, and heart rate variability may vary from person to person. However, heart rate variability is an example of biometric information and is not limited thereto.

[0181] According to an embodiment, in operation S1303, the wearable device (200) can identify whether the similarity between the biometric information and the biometric information previously stored in the memory (242) is greater than or equal to a threshold value. For example, the wearable device (200) can compare the heart rate variability with the previously stored heart rate variability and identify whether the similarity is greater than or equal to the threshold value, thereby identifying whether the wearable device (200) is worn by a previously registered user.

[0182] For example, in operations S1303-Y and S1304, the wearable device (200) may activate the second sensor (246) and the third sensor (247) if the similarity between the biometric information and the previously stored biometric information is greater than a threshold value.

[0183] For example, in operation S1303-N, the wearable device (200) may deactivate (or maintain deactivation of) the second sensor (246) and the third sensor (247) if the similarity between the biometric information and the previously stored biometric information is below a threshold value.

[0184] For example, if the similarity between the biometric information and the previously stored biometric information is below a threshold value, the wearable device (200) can control the PMIC (249) to disable the second sensor (246) and the third sensor (247) by not supplying power to each of the second sensor (246) and the third sensor (247).

[0185] However, it is not limited thereto. For example, if the similarity between the biometric information and the previously stored biometric information is less than a threshold value, the wearable device (200) may not transmit the contact detected through the second sensor (246) (e.g., finger contact detected on the outer surface) to the processor (241) or may not transmit the acceleration change detected through the third sensor (247) to the processor (241). That is, since the wearable device (200) does not transmit the second sensing data acquired through the second sensor (246) and the third sensing data acquired through the third sensor (247) to the processor (241), the second sensor (246) and the third sensor (247) may be deactivated.

[0186] For example, the wearable device (200) transmits each of the second sensing data acquired through the second sensor (246) and the third sensing data acquired through the third sensor (247) to the processor (241), but the processor (241) of the wearable device (200) does not process the second sensing data and the third sensing data (or ignores each of the second sensing data and the third sensing data), and the second sensor (246) and the third sensor (247) may be deactivated.

[0187] According to the implementation, operations S1305 to S1311 are identical to operations S830 to S890 illustrated in FIG. 8, so redundant descriptions are omitted.

[0188]

[0189] FIG. 14A is a flowchart illustrating a method for controlling a wearable device by identifying the number of rotations according to an embodiment of the present disclosure.

[0190] According to the embodiment, operations S1401 to S1406 are identical to operations S1301 to S1306 illustrated in FIG. 13, so redundant descriptions are omitted.

[0191] According to an embodiment, in operation S1407, the wearable device (200) may identify a first interaction for rotating the wearable device (200) based on an acceleration change included in the third sensing data. According to an embodiment, the first interaction may include an operation for rotating the wearable device (200) (identified in operation S1407) using a second finger (identified in operation S1405) that is in contact with an outer surface of the wearable device (200) inserted into a first finger.

[0192] According to an embodiment, the wearable device (200) may identify the number of rotations of the wearable device (200) according to the first interaction. For example, the wearable device (200) may identify the number of rotations of the wearable device (200) based on whether the wearable device (200) is rotated, rather than the rotational length according to the rotation of the wearable device (200).

[0193] For example, the wearable device (200) can identify the first rotation (or first rotation) of the wearable device (200) according to the first interaction in operation S1408.

[0194] For example, if a rotation of the wearable device (200) exceeding 1 cm, which can be assumed to be a rotation according to the user's intention rather than a rotation due to the user's activity (or a rotation of the wearable device (200) that is not intended by the user), is detected, the wearable device (200) can identify the first rotation (or the first rotation) of the wearable device (200).

[0195] In operation S1409 according to an embodiment, if the first interaction is not identified (or, if the rotation of the wearable device (200) according to the first interaction is stopped), the wearable device (200) may determine whether the rotation of the wearable device (200) according to the first interaction is identified within a preset first time (e.g., 1 second).

[0196] According to an embodiment, in operations S1409-Y and S1410, if the first interaction is re-identified within a preset first time, the wearable device (200) may identify the final number of rotations of the wearable device (200) as the first rotation, and may identify a control command corresponding to the number of rotations of the first rotation. For example, the wearable device (200) may identify the final number of rotations of the wearable device (200) as the first rotation by adding the rotations of the wearable device (200) re-identified within the preset first time to the previous rotations.

[0197] For example, if the wearable device (200) rotates (first rotation) according to the first interaction and then rotates again according to the first interaction within a preset first time, the wearable device (200) can identify a control command according to the first rotation.

[0198] For example, if the rotation of the wearable device (200) is stopped after a rotation of more than 1 cm is detected in operation S1408, and a rotation of the wearable device (200) of more than 1 cm is detected again within a preset first time in operation S1409-Y, the number of rotations of the wearable device (200) may not be increased, and the number of rotations may be identified as the first rotation (or, the first rotation).

[0199] In operation S1411, the wearable device (200) can control the electronic device (100) by transmitting a control command corresponding to the first rotation to the electronic device (100).

[0200] In the embodiments, in operations S1409-N and S1412, if the first interaction is not re-identified within a preset first time (or if the first interaction is interrupted for more than the preset first time), the wearable device (200) may determine whether the first interaction is re-identified within a preset second time (e.g., 2 seconds).

[0201] In operation S1412-N, S1410, if the first interaction is not re-identified within the preset second time, the wearable device (200) can identify the final number of rotations of the wearable device (200) as the first rotation, and identify a control command corresponding to the number of rotations of the first rotation.

[0202] For example, if rotation of the wearable device (200) is stopped after rotation of more than 1 cm is detected in operation S1408, and rotation of the wearable device (200) of more than 1 cm is not detected again between a preset first time and a preset second time (e.g., between 1 second and 2 seconds) in operations S1409-N and S1412-N, the final number of rotations of the wearable device (200) can be identified as the first rotation.

[0203] In operations S1412-Y and S1413, if the first interaction is re-identified within a preset second time, the wearable device (200) can identify the number of rotations of the wearable device (200) as a second rotation and identify a control command corresponding to the number of rotations of the second rotation. However, the present invention is not limited thereto, and according to an embodiment, the wearable device (200) can identify a rotation exceeding a preset length (or a preset angle) as a second rotation. For example, if the wearable device (200) rotates more than 360 degrees according to the first interaction, the wearable device (200) can increase the number of rotations and identify it as a second rotation. For example, the wearable device (200) may rotate according to the first interaction, and the number of rotations may be increased by one each time the rotation angle of the wearable device (200) exceeds 360 degrees.

[0204] For example, if the rotation of the wearable device (200) is stopped after a rotation of more than 1 cm is detected in operation S1408, and a rotation of the wearable device (200) of more than 1 cm is detected again between a preset first time and a preset second time (for example, between 1 second and 2 seconds) in operations S1409-N and S1412-Y, the final number of rotations of the wearable device (200) can be identified as a second rotation (or second rotation).

[0205] In operation S1414, the wearable device (200) can transmit a control command corresponding to the second rotation to the electronic device (100).

[0206] In an embodiment according to FIG. 14a, the wearable device (200) can identify the number of rotations of the wearable device (200), rather than the rotation length (or rotation angle), and can identify a control command corresponding to the number of rotations among a plurality of control commands and transmit the control command to the electronic device (100).

[0207]

[0208]

[0209] *Figure 14b is a drawing for explaining a control command according to the number of rotations according to an embodiment of the present disclosure.

[0210] Referring to FIG. 14b, an electronic device (100) communicating with a wearable device (200) can provide a user interface (UI) for setting a control command corresponding to each number of rotations.

[0211] For example, the electronic device (100) can control the display (140) to display a user interface (UI) for setting a control command corresponding to each number of rotations of the wearable device (200).

[0212] According to an embodiment, the electronic device (100) may set, based on a user command for the UI, whether to activate (e.g., On / Off) the connection performance (or continuous performance) of an action (e.g., a control command) according to the rotation of the wearable device (200) (e.g., connection performance of a designated action of FIG. 14b), the number of rotations, a control command corresponding to each number of rotations, and whether to activate (e.g., On / Off) a control command corresponding to each of a plurality of sections.

[0213] According to an embodiment, the electronic device (100) may transmit information about a control command corresponding to each number of rotations to the wearable device (200). According to an embodiment, the information about the control command corresponding to each number of rotations may include the number of rotations (e.g., 1st rotation, 2nd rotation, 3rd rotation, etc.), the control command corresponding to each number of rotations (e.g., 1st control command corresponding to 1st rotation, 2nd control command corresponding to 2nd rotation, 3rd control command corresponding to 3rd rotation, etc.), and whether the control command corresponding to each number of rotations is activated (e.g., On / Off).

[0214]

[0215] For example, the wearable device (200) can detect the rotation of the wearable device (200) according to the first interaction. When the rotation of the wearable device (200) stops, the wearable device (200) can identify the first rotation of the wearable device (200) and can identify whether the rotation of the wearable device (200) according to the first interaction is detected again within a preset first time (e.g., 1 second).

[0216] According to an embodiment, if the rotation of the wearable device (200) according to the first interaction is re-detected within a preset first time, the wearable device (200) can identify the rotation number for the first time without increasing the rotation number of the wearable device (200).

[0217] According to an embodiment, the wearable device (200) may identify the number of times the wearable device (200) has rotated so far, that is, a control command corresponding to the first rotation, and transmit the control command to the electronic device (100) if the rotation of the wearable device (200) according to the first interaction is not identified for a preset second time (e.g., 2 seconds) or longer based on information about a control command corresponding to each number of rotations.

[0218]

[0219] According to an embodiment, if the rotation of the wearable device (200) according to the first interaction is not re-detected within a preset first time period, and if the rotation of the wearable device (200) according to the first interaction is re-detected within a preset second time period after the preset first time period, the number of rotations of the wearable device (200) can be increased to identify the number of rotations for the second time period.

[0220] According to an embodiment, the wearable device (200) identifies a first rotation according to a first interaction, and if the rotation of the wearable device (200) according to the first interaction is detected again within a preset second time (e.g., 2 seconds) after a preset first time (e.g., 1 second) after the rotation of the wearable device (200) has stopped, the second rotation is identified, and if the rotation is not identified for more than the preset second time after the re-rotation of the wearable device (200) has stopped, the wearable device (200) identifies the number of times the wearable device (200) has rotated so far, that is, the control command corresponding to the second rotation, based on information about the control command corresponding to each number of rotations, and transmits the control command to the electronic device (100).

[0221] According to the embodiment, each of the first preset time and the second preset time may be changed in various ways depending on user settings, manufacturer settings, etc.

[0222] According to an embodiment, when a control command is received from a wearable device (200), the electronic device (100) can control the electronic device (100) based on the control command.

[0223] However, the present invention is not limited thereto, and when the number of rotations of the wearable device (200) is received from the wearable device (200), the electronic device (100) may control the electronic device (100) by identifying a control command corresponding to the number of rotations made so far based on information about the control command corresponding to each number of rotations.

[0224] For example, if the first interaction is not identified for a preset second time (e.g., 2 seconds), the wearable device (200) transmits the number of times the wearable device (200) has rotated so far to the electronic device (100), and the electronic device (100) can identify a control command based on the number of times the wearable device (200) has rotated so far.

[0225]

[0226] FIG. 15 is a flowchart illustrating a method for controlling a wearable device by identifying the number of rotations in an embodiment of the present disclosure.

[0227] According to the embodiment, operations S1501 to S1508 are the same as operations S1401 to S1408 illustrated in Fig. 14a, so redundant descriptions are omitted.

[0228] According to an embodiment, in operation S1509, when the rotation of the wearable device (100) is identified according to the first interaction, the wearable device (200) can identify the first rotation (or the first rotation) and identify a control command corresponding to the first rotation.

[0229] For example, the wearable device (200) may identify the number of rotations of the wearable device (200) based on whether the wearable device (200) is rotated, rather than the rotation length according to the rotation of the wearable device (200). For example, in operation S1509, the wearable device (200) may identify the first rotation (or first rotation) of the wearable device (200) according to the first interaction.

[0230] In operation S1510 according to an embodiment, if the first interaction is not identified (or, if the rotation of the wearable device (200) according to the first interaction is stopped), the wearable device (200) can determine whether the rotation of the wearable device (200) according to the first interaction is re-identified within a preset first time.

[0231] For example, the wearable device (200) can determine whether the rotation of the wearable device (200) according to the first interaction is re-identified within a preset first time (e.g., 1 second).

[0232] In the embodiments, in operations S1510-N and S1511, the wearable device (200) may determine whether the first interaction is re-identified within a preset first time (or, if the first interaction is interrupted for more than a preset time), or whether the first interaction is re-identified within a preset second time.

[0233] According to an embodiment, in operations S1512-Y and S1513, if the first interaction is re-identified within a preset second time, the wearable device (200) can identify the number of rotations of the wearable device (200) as a second rotation and identify a control command corresponding to the second rotation.

[0234] For example, if the wearable device (200) stops rotating after a rotation of more than 1 cm is detected in operations S1508 and S1509, the wearable device (200) can identify a control command corresponding to the first rotation.

[0235] For example, if a rotation of the wearable device (200) exceeding 1 cm is re-detected between a preset first time and a preset second time (e.g., between 1 second and 2 seconds) in operations S1510-N, S1512-Y, and S1513, the wearable device (200) can identify a control command corresponding to the second rotation.

[0236] According to an embodiment, the wearable device (200) can control the electronic device (100) by transmitting a control command corresponding to the first rotation identified in operation S1509 and a control command corresponding to the second rotation identified in operation S1513 to the electronic device (100) in operation S1514.

[0237] For example, when the wearable device (200) is rotated for the first time and then rotated for the second time between a preset first time and a preset second time, the wearable device (200) can control the electronic device (100) by simultaneously (or consecutively) transmitting a control command corresponding to the first rotation (e.g., activation of the do not disturb mode of FIG. 14b) and a control command corresponding to the second rotation (e.g., start of bicycle exercise of FIG. 14b) to the electronic device (100).

[0238] For example, as illustrated in FIG. 14b, depending on whether the connection performance (or continuous performance) of an action (e.g., a control command) according to the rotation of the wearable device (200) is activated (e.g., On / Off) (e.g., connection performance of a designated action in FIG. 14b), when the wearable device (200) is rotated for the first time while the connection performance of the designated action is activated (e.g., On), and the wearable device (200) is rotated for the second time between a preset first time and a preset second time, the control command corresponding to the first rotation and the control command corresponding to the second rotation can be transmitted to the electronic device (100) simultaneously (or continuously).

[0239] For example, when the wearable device (200) is rotated for the first time and rotated for the second time between a preset first time and a preset second time in a state where the connection execution of a designated action is disabled (e.g., Off), the wearable device (200) may identify the final rotation count of the wearable device (200) as the second rotation (or second rotation), and transmit only the control command corresponding to the second rotation to the electronic device (100) (e.g., S1412-Y, S1413, S1414 of FIG. 14a).

[0240]

[0241] According to an embodiment, in operations S1512-N and S1511, if the first interaction is not re-identified within a preset second time, the wearable device (200) identifies the number of rotations of the wearable device (200) as the first rotation (i.e., since the second rotation of the wearable device (200) is not identified), and transmits a control command corresponding to the first rotation identified in operation S1509 to the electronic device (100) in operation S1511 to control the electronic device (100).

[0242] According to an embodiment, in operation S1510-Y, if a first interaction is identified within a preset first time (e.g., 1 second), the wearable device (200) may not increase the number of rotations, identify the number of rotations as the first rotation, and transmit a control command corresponding to the first rotation to the electronic device (100) in operation S1511. For example, the wearable device (200) may identify the number of rotations of the wearable device (200) re-identified within the preset first time as the first rotation by adding it to the previous rotation.

[0243]

[0244] FIG. 16 is a flowchart illustrating a method for controlling an electronic device by identifying a rotation direction according to an embodiment of the present disclosure.

[0245] According to the implementation, operations S1601 to S1605 are identical to operations S810 to S850 illustrated in FIG. 8, so redundant descriptions are omitted.

[0246] According to an embodiment, in operation S1606, the wearable device (200) can identify a rotation direction according to the rotation of the wearable device (200) based on third sensing data acquired through the third sensor (247). According to an embodiment, the rotation direction may include a first direction (e.g., clockwise) and a second direction (e.g., counterclockwise).

[0247] According to an embodiment, in operation S1606-first direction, in operation S1607, if the rotational direction of the wearable device (200) is identified as the first direction, the wearable device (200) can identify a control command corresponding to the first direction. For example, if the wearable device (200) rotates in a clockwise direction, the wearable device (200) can identify a first control command corresponding to the clockwise direction.

[0248] According to an embodiment, in operation S1608, the wearable device (200) may transmit a control command corresponding to the first direction to the electronic device (100).

[0249] According to an embodiment, the wearable device (200) may identify a control command corresponding to the second direction when the rotation direction of the wearable device (200) is identified as the second direction in operations S1606-2nd direction and S1609. For example, when the wearable device (200) rotates counterclockwise, the wearable device (200) may identify a second control command corresponding to the counterclockwise direction.

[0250] According to an embodiment, in operation S1610, the wearable device (200) can control the electronic device (100) by transmitting a control command corresponding to the second direction to the electronic device (100).

[0251]

[0252] FIG. 17 is a drawing for explaining a control command according to a rotation direction according to an embodiment of the present disclosure.

[0253] Referring to FIG. 17, an electronic device (100) communicating with a wearable device (200) can provide a user interface (UI) for setting a control command according to the rotation direction of the wearable device (200).

[0254] For example, the electronic device (100) can control the display (140) to display a user interface (UI) for setting a control command corresponding to a first direction of the wearable device (200) and a control command corresponding to a second direction.

[0255] According to an embodiment, the electronic device (100) can set a control command corresponding to a first direction and a control command corresponding to a second direction, respectively, based on a user command for the UI, and can set whether the control commands are activated (e.g., On / Off).

[0256] According to an embodiment, the electronic device (100) may set a control command corresponding to a combination (or pattern) of a first direction and a second direction. For example, a control command (e.g., door lock open) corresponding to a combination (first direction -> second direction -> first direction) may be set.

[0257] According to an embodiment, when a rotation corresponding to a combination of a first direction and a second direction is identified (e.g., when the wearable device (200) sequentially rotates in the first direction -> second direction -> first direction), the wearable device (200) may transmit a control command to the electronic device (100). For example, the electronic device (100) is an IoT device (e.g., a door lock), and the control command may include lock setting, lock unlocking, etc.

[0258]

[0259] FIG. 18 is a flowchart illustrating a method for controlling an electronic device by identifying a tap input according to an embodiment of the present disclosure.

[0260] Since operations S1801 to S1803 of FIG. 18 are identical to operations S810 to S830 illustrated in FIG. 8, duplicate descriptions will be omitted.

[0261] According to an embodiment, in operation S1804, the wearable device (200) can identify a second interaction in which a second finger taps the outer surface through the second sensor (246).

[0262] According to an embodiment, in operation S1805, the wearable device (200) can identify the number of taps by the second finger.

[0263] For example, the wearable device (200) can identify the number of taps on the outer surface based on the second sensing data of the second sensor (246).

[0264] According to an embodiment, the wearable device (200) may determine whether a tap according to the second interaction is identified within a preset time period, if the second interaction is not identified (or the tap according to the second interaction is stopped), after the second interaction of tapping the outer surface is identified in operation S1805-single tap, S1806.

[0265] According to an embodiment, in operation S1805-Single Tap, S1806, if the second interaction is not identified for a preset time or longer (or, if the second interaction is interrupted for a preset time or longer), the wearable device (200) can identify the number of taps as 1 (single tap) and identify a control command corresponding to the single tap.

[0266] In operation S1807, the wearable device (200) can transmit a control command corresponding to a single tap to the electronic device (100).

[0267] According to an embodiment, in operation S1805-Double Tap, S1808, after a second interaction of tapping the outer surface is identified, if the second interaction is re-identified within a preset time, the wearable device (200) can identify the number of taps as two (double tap) and identify a control command corresponding to the double tap.

[0268] In operation S1809, the wearable device (200) can control the electronic device (100) by transmitting a control command corresponding to a double tap to the electronic device (100).

[0269]

[0270] FIG. 19 is a drawing for explaining a control command according to a tap input according to an embodiment of the present disclosure.

[0271] Referring to FIG. 19, an electronic device (100) communicating with a wearable device (200) may provide a user interface (UI) for setting a control command corresponding to each number of taps.

[0272] For example, the electronic device (100) can control the display (140) to display a user interface (UI) for setting a control command corresponding to each number of taps of the wearable device (200).

[0273] According to an embodiment, the electronic device (100) may set the number of taps (e.g., single tap, double tap, triple tap), control commands corresponding to each number of taps (e.g., control commands corresponding to single tap, control commands corresponding to double tap, control commands corresponding to triple tap), and whether control commands corresponding to each number of taps are activated (e.g., On / Off) based on a user command for the UI.

[0274] According to an embodiment, the electronic device (100) can transmit information about a control command corresponding to each number of taps set through the UI to the wearable device (200).

[0275] According to an embodiment, the wearable device (200) may identify a control command corresponding to the number of times the outer surface has been tapped up to now and transmit the control command to the electronic device (100) if a tap according to the second interaction is not identified for a preset time based on information about a control command corresponding to each number of taps.

[0276] According to an embodiment, when a control command is received from a wearable device (200), the electronic device (100) can control the electronic device (100) based on the control command.

[0277] However, the present invention is not limited thereto, and when the number of taps is received from the wearable device (200), the electronic device (100) may control the electronic device (100) by identifying a control command corresponding to the number of times the outer surface has been tapped so far based on information about the control command corresponding to each number of taps.

[0278] For example, if the second interaction is not identified for a preset period of time (or if the second interaction is interrupted for a preset period of time), the wearable device (200) transmits the number of times the outer surface is tapped to the electronic device (100), and the electronic device (100) can identify a control command based on the number of times the outer surface is tapped.

[0279]

[0280] FIG. 20 is a flowchart illustrating a method for controlling an electronic device by obtaining a fingerprint according to an embodiment of the present disclosure.

[0281] According to an embodiment, the wearable device (200) can detect whether a first finger is inserted into the wearable device (200) through the first sensor (250) in operation S2001.

[0282] According to an embodiment, the wearable device (200) can identify a third interaction of pressing the outer surface through the second sensor (246) after the insertion of the first finger into the wearable device (200) is detected in operations S2001-Y and S2002.

[0283] Depending on the embodiment, the second sensor (246) may include a touch sensor and / or a fingerprint sensor.

[0284] According to an embodiment, in operation S2003, the wearable device (200) can detect a fingerprint according to a third interaction in which a second finger presses the outer surface.

[0285] For example, the wearable device (200) can obtain a fingerprint image based on second sensing data received from the touch sensor and / or fingerprint sensor of the second sensor (246).

[0286] According to an embodiment, in operation S2004, the wearable device (200) can identify whether the similarity between the fingerprint image and the previously stored fingerprint image is greater than a threshold value.

[0287] According to an embodiment, in operations S2004-Y and S2005, the wearable device (200) may transmit a control command to the electronic device (100) if the similarity between the fingerprint image and the previously stored fingerprint image is greater than a threshold value.

[0288] According to an embodiment, if the similarity between the identified fingerprint image and the previously stored fingerprint image is greater than a threshold value, the wearable device (200) may transmit a control command (e.g., a lock setting command, an unlocking command, etc.) to the electronic device (100) (e.g., a user terminal device, an IoT device (e.g., a door lock)).

[0289] According to an embodiment, in operation S2004-N, the wearable device (200) may not transmit a control command to the electronic device (100) if the similarity between the identified fingerprint and the previously stored fingerprint is less than a threshold value.

[0290] However, this is not limited thereto. For example, the wearable device (200) may obtain a fingerprint image and transmit the fingerprint image to the electronic device (100) in operation S2003. According to an embodiment, when the electronic device (100) receives a fingerprint image, it may compare the similarity with a fingerprint previously stored in the electronic device (100) and identify whether the similarity between the fingerprint image and the previously stored fingerprint image is greater than a threshold value, as in operation S2004.

[0291] According to an embodiment, if the similarity between a fingerprint image and a previously stored fingerprint image is greater than a threshold value, the electronic device (100) can identify a control command and operate according to the control command.

[0292]

[0293] According to an embodiment, the wearable device (200) can store multiple fingerprint images. According to an embodiment, in operation S2004, the wearable device (200) can compare the fingerprint image with multiple previously stored fingerprint images.

[0294] According to an embodiment, if the wearable device (200) identifies that the similarity between the fingerprint image acquired in operation S2003 and the first fingerprint image stored among the plurality of previously stored fingerprint images is greater than a threshold value, the wearable device (200) may acquire a first control command preset to correspond to the first fingerprint image stored in the first fingerprint image.

[0295] According to an embodiment, the wearable device (200) may transmit a first control command to the electronic device (100). For example, the wearable device (200) may store fingerprint images corresponding to each of a plurality of users, and may compare the fingerprint image acquired in operation S2003 with the plurality of previously stored fingerprint images to identify the first fingerprint image corresponding to the first user among the plurality of previously stored fingerprint images as having the highest similarity.

[0296] According to an embodiment, if the wearable device (200) identifies that the fingerprint image acquired in operation S2003 has the highest similarity with the first fingerprint image, the wearable device (200) may transmit a first control command (e.g., unlocking with an account corresponding to the first user, or logging in with an account corresponding to the first user) preset to correspond to the first fingerprint image to the electronic device (100).

[0297] However, the present invention is not limited thereto, and for example, the wearable device (200) may compare the fingerprint image acquired in operation S2003 with a plurality of previously stored fingerprint images and identify a second fingerprint image corresponding to the second user among the plurality of previously stored fingerprint images as having the highest similarity. For example, if the wearable device (200) identifies that the fingerprint image acquired in operation S2003 and the second fingerprint image have the highest similarity, the wearable device (200) may transmit a first control command preset to correspond to the second fingerprint image (e.g., unlocking with an account corresponding to the second user, or logging in with an account corresponding to the second user) to the electronic device (100).

[0298]

[0299] According to an embodiment, the wearable device (200) may store fingerprint images corresponding to each of a plurality of electronic devices. For example, the wearable device (200) may compare the fingerprint image acquired in operation S2003 with a plurality of pre-stored fingerprint images and identify the first fingerprint image corresponding to the first electronic device as having the highest similarity among the plurality of pre-stored fingerprint images. According to an embodiment, when the wearable device (200) identifies the fingerprint image acquired in operation S2003 as having the highest similarity with the first fingerprint image, the wearable device (200) may transmit a control command (e.g., turning on / off the first electronic device, controlling the volume, unlocking, etc.) to the first electronic device preset to correspond to the first fingerprint image.

[0300] However, the present invention is not limited thereto, and for example, the wearable device (200) may compare the fingerprint image acquired in operation S2003 with a plurality of previously stored fingerprint images and identify a second fingerprint image corresponding to the second electronic device among the plurality of previously stored fingerprint images as having the highest similarity. For example, if the wearable device (200) identifies that the fingerprint image acquired in operation S2003 and the second fingerprint image have the highest similarity, the wearable device (200) may transmit a control command (e.g., turning the second electronic device on / off, controlling the volume, unlocking, etc.) to the second electronic device that is preset to correspond to the second fingerprint image.

[0301] Meanwhile, in the above-described example, it is assumed that the wearable device (200) obtains a fingerprint image and compares the fingerprint image with a previously stored fingerprint image to identify the similarity, but of course, the present invention is not limited thereto. For example, the wearable device (200) may obtain a fingerprint image and transmit the fingerprint image to the electronic device (100). The electronic device (100) may compare the received fingerprint image with a previously stored fingerprint image in the electronic device (100) (or server) to identify the similarity, and may obtain a control command for controlling the electronic device (100) or an external electronic device based on the identified similarity.

[0317] According to an embodiment, when the wearable device (200) detects the removal (or detachment) of a first finger inserted into the wearable device (200) based on the first sensing data of the first sensor (250), the wearable device (200) may transmit a control command corresponding to a sixth interaction resulting from the removal of the first finger to the electronic device (100).

[0318] For example, when the removal of the first finger is detected through the first sensor (250), the wearable device (200) can transmit a control command to the electronic device (100) for controlling the electronic device (100), such as a lock setting command for the electronic device (100) or a power-off command for the electronic device (100).
