Referring to FIG. 3, the wearable device 101 may include a first support portion 201, a second support portion 202, a connection portion 203, and an actuator 240.

According to an embodiment of the disclosure, the wearable device 101 may be formed to be worn on a lower body of a user. For example, the first support portion 201 may be fixed to a waist or hips of the user.

The connection portion 203-2 may rotatably connect the second support portion 202-2 with respect to the first support portion 201 through the actuator 240-2.

According to an embodiment of the disclosure, the actuator 240 may occur torque for resisting moving of the user (e.g., walking). For example, the actuator 240 may occur resist torque. The actuator 240 may occur torque to occur a force in a direction opposite to the direction in which the user lifts the leg when the user lifts the leg. The actuator 240 may occur torque to occur a force in a direction opposite to the direction in which the user lowers the leg when the user changes from a state in which the leg is raised to a state in which the leg is lowered.

According to an embodiment of the disclosure, the actuator 240 may occur torque for assisting the moving of the user (e.g., walking). For example, the actuator 240 may occur assist torque. The actuator 240 may occur torque to occur a force in a direction corresponding to the direction in which the user lifts the leg when the user lifts the leg. The actuator 240 may occur torque to occur a force in a direction corresponding to the direction in which the user lowers the leg when the user changes from a state in which the leg is raised to a state in which the leg is lowered.

According to an embodiment of the disclosure, the actuator 240-1 and the actuator 240-2 may output (or occur) torque in different ranges. For example, in case that the user of the wearable device 101 walks on a sidewalk inclined to one side, the wearable device 101 may assist the moving of the user by outputting torque in different ranges from the actuator 240-1 and the actuator 240-2.

FIG. 4 illustrates an operation mode of a wearable device according to an embodiment of the disclosure.

Referring to FIG. 4, the wearable device 101 may operate in a plurality of operation modes to assist or resist moving of a user. For example, the plurality of operation modes in which the wearable device 101 operates may include a plurality of operation modes for outputting assist torque and a plurality of operation modes for outputting resist torque. The plurality of operation modes in which the wearable device 101 operates may include an operation mode that does not output torque. In each operation mode, the wearable device 101 may output torque having values within different designated ranges.

For example, the resist torque and the assist torque may act in opposite directions. For an example, the resist torque may act in a direction for resisting a movement of the user. The assist torque may act in a direction for assisting the movement of the user.

Magnitude of the resist torque may have values that change according to a posture (e.g., posture according to walking) of the user. The magnitude of the resist torque may have the values that change according to the posture (e.g., posture according to walking) of the user. For convenience of description, the magnitude of the resist torque may be described as corresponding to magnitude of a force for resisting the movement of the user. Magnitude of the assist torque may be described as corresponding to magnitude of a force for assisting the movement of the user.

For example, the plurality of operation modes for outputting the assist torque may include an assist 1 mode 411, an assist 2 mode 412, an assist 3 mode 413, an assist 4 mode 414, and an assist 5 mode 415. In the assist 5 mode 415, the magnitude of the assist torque may be set to be the greatest. In the assist 1 mode 411, the magnitude of the assist torque may be set to be the smallest. As a mode changes from the assist 5 mode 415 to the assist 1 mode 411, a processor 220 of the wearable device 101 may reduce the magnitude of the assist torque. For example, as the mode changes from the assist 5 mode 415 to the assist 1 mode 411, the processor 220 may reduce the magnitude of the assist torque by changing a designated range. For an example, in the assist 1 mode 411, the processor 220 may output torque having values within a first designated range. In an assist 2 mode 412, the processor 220 may output torque having values within a second designated range. A first force for assisting the movement of the user acting through the torque having values within the second designated range may be set to be greater than a second force for assisting the movement of the user acting through the torque having values within the first designated range.

For example, in a zero mode 400, the processor 220 may not output torque. The zero mode 400 may be referred to as an assist 0 mode or a resist 0 mode.

For example, the plurality of operation modes for outputting the resist torque may include a resist 1 mode 421, a resist 2 mode 422, a resist 3 mode 423, a resist 4 mode 424, and a resist 5 mode 425. In the resist 5 mode 425, the magnitude of the resist torque may be set to be the greatest. In the resist 1 mode 421, the magnitude of the resist torque may be set to be the smallest.

As a mode changes from the resist 1 mode 421 to the resist 5 mode 425, the processor 220 may increase the magnitude of the resist torque. For example, as the mode changes from the resist 1 mode 421 to the resist 5 mode 425, the processor 220 may increase the magnitude of the resist torque by changing the designated range. For example, as the mode changes from the resist 1 mode 421 to the resist 5 mode 425, the processor 220 may increase the magnitude of the resist torque by changing the designated range. For an example, in the resist 1 mode 421, the processor 220 may output torque having values within the first designated range. In a resist 2 mode 422, the processor 220 may output torque having values within the second designated range. A first force for resisting the movement of the user, acting through the torque having values within the second designated range, may be set to be greater than a second force for resisting the movement of the user, acting through the torque having values within the first designated range.

FIG. 4 illustrates a plurality of operation modes of a wearable device, but this is exemplary and is not limited thereto. Contrary to the above-described example, the operation mode of the wearable device 101 may be set in various ways and referred to by various names.

For example, nine modes may be further included between the two adjacent operation modes described above. For an example, nine modes may be further included between a resist 4 mode 414 and a resist 3 mode 413. A resist 4.1 mode to a resist 4.9 mode may be included between the resist 4 mode 414 and the resist 3 mode 413.

FIG. 5 illustrates an operation of a wearable device for interval training according to an embodiment of the disclosure.

Referring to FIG. 5, a processor 220 of the wearable device 101 may operate according to an exercise program for interval training. For example, the wearable device 101 may operate to change magnitude of resist torque (or assist torque) for each section (e.g., time interval or distance). The processor 220 may change exercise intensity according to a designated interval.

According to an embodiment of the disclosure, the processor 220 may change torque within a first designated range (or a second designated range) in a period of a designated time or a designated distance. For example, the processor 220 may alternately output the torque within the first designated range and torque within the second designated range in a period of the designated distance. For another example, the processor 220 may alternately output the torque within the first designated range and the torque within the second designated range in a period of the designated time.

According to an embodiment of the disclosure, the processor 220 may change the magnitude of the resist torque based on the time interval. For example, in an interval 512 from a timing 501 to a timing 502, the wearable device 101 may operate in a resist 1 mode. In an interval 523 from the timing 502 to a timing 503, the wearable device 101 may operate in a resist 5 mode. In an interval 534 from the timing 503 to a timing 504, the wearable device 101 may operate in a resist 2 mode. In an interval 545 from the timing 504 to a timing 505, the wearable device 101 may operate in a resist 4 mode.

FIG. 5 illustrates an operation of the wearable device 101 for interval training, but is not limited thereto. For example, the wearable device 101 may change the operation mode of the wearable device 101 based on a distance. For an example, in an interval from a first location to a second location, the wearable device 101 may operate in the resist 1 mode. In an interval from the second location to a third location, the wearable device 101 may operate in the resist 5 mode.

According to an embodiment of the disclosure, the wearable device 101 may receive a user input for total exercise time from a user. In case that the user input for the total exercise time is received, the wearable device 101 may change the operation mode of the wearable device 101 based on the time interval.

According to an embodiment of the disclosure, the wearable device 101 may receive a user input for a total exercise distance from the user. In case that the user input for the total exercise distance is received, the wearable device 101 may change the operation mode of the wearable device 101 based on the distance.

According to an embodiment of the disclosure, the wearable device 101 may repeatedly (or periodically) change the operation mode of the wearable device 101. In case that the operation mode of the wearable device 101 is repeatedly (or periodically) changed, injury to the user may occur. According to an embodiment of the disclosure, the wearable device 101 may identify a motion of the user and change the operation mode (or torque outputted from the wearable device 101) of the wearable device 101 based on this. An example of the operation of the wearable device 101 according to the above embodiment may be described below.

FIG. 6 is a flowchart for illustrating an operation of a wearable device according to an embodiment of the disclosure. Such a method may be executed by the wearable device 101 and a processor 220 of the wearable device 101 illustrated in FIGS. 2 and 3.

Referring to FIG. 6, in operation 610, the processor 220 may obtain motion data of a user. For example, the processor 220 may obtain the motion data of the user wearing the wearable device 101 through at least one sensor 230.

According to an embodiment of the disclosure, the motion data of the user may include motion data measurable while the user is wearing the wearable device 101. For example, the processor 220 may obtain data on a movement of a pelvis of the user, data on speed at which a leg of the user moves, and data on an angle at which a hip joint of the user moves.

According to an embodiment of the disclosure, the motion data of the user may be obtained through an external electronic device connected with the wearable device 101. For example, an external electronic device wearable on an arm of the user may obtain data on the movement of the arm of the user. The wearable device 101 may obtain data on the movement of the arm of the user from the external electronic device. For another example, an external electronic device capable of measuring a heart rate of the user may obtain data on the heart rate of the user. The wearable device 101 may obtain data on the heart rate of the user from the external electronic device.

In operation 620, the processor 220 may set an operation mode of the wearable device 101 to a first operation mode. For example, the processor 220 may set the operation mode of the wearable device 101 to the first operation mode based on the motion data of the user. For example, the processor 220 may output torque having values within a first designated range through an actuator 240 based on the motion data of the user.

For example, the processor 220 may identify that the user has started to move based on the motion data of the user. The processor 220 may set the operation mode of the wearable device 101 to the first operation mode based on identifying that the user has started to move.

For another example, the processor 220 may identify information on stride length of the user based on the motion data of the user. The processor 220 may set the operation mode of the wearable device 101 to the first operation mode based on information on the stride length of the user.

For another example, the processor 220 may identify information on a moving velocity of the user based on the motion data of the user. The processor 220 may set the operation mode of the wearable device 101 to the first operation mode based on the information on the moving velocity of the user.

For another example, the processor 220 may identify torque caused by the user based on the motion data of the user. The processor 220 may set the operation mode of the wearable device 101 to the first operation mode based on the torque caused by the user. For example, torque may occur according to walking of the user. The processor 220 may identify the torque that occurs according to the walking of the user. The processor 220 may set the operation mode of the wearable device 101 to the first operation mode based on the torque that occurs according to the walking of the user.

The processor 220 may set the operation mode of the wearable device 101 to the first operation mode based on the information on the operation record of the user and the motion data of the user.

In operation 630, the processor 220 may, after setting the operation mode of the wearable device 101 to the first operation mode, provide a notification, based on identifying a timing to provide the notification.

According to an embodiment of the disclosure, the processor 220 may identify that reference time has elapsed from a timing at which the operation mode of the wearable device 101 is set to the first operation mode. The processor 220 may identify a timing at which the reference time has elapsed from the timing at which the operation mode of the wearable device 101 is set to the first operation mode. The processor 220 may identify the timing at which the reference time has elapsed from the timing at which the operation mode of the wearable device 101 is set to the first operation mode as a timing for providing the notification. For example, the processor 220 may identify that the operation mode of the wearable device 101 set to the first operation mode has been maintained for the reference time.

For example, the processor 220 may identify a timing to change the operation mode of the wearable device 101 after setting the operation mode of the wearable device 101 to the first operation mode. The processor 220 may identify the timing for providing the notification based on the identified timing.

Within first time interval, the processor 220 may set the wearable device 101 to operate in the first operation mode. Within second time interval after the first time interval, the processor 220 may set the wearable device 101 to operate in a second operation mode.

The processor 220 may identify from the timing at which the operation mode of the wearable device 101 is set to the first operation mode from a timing at which the second time interval starts to before a designated time as the reference time. The processor 220 may identify from a timing at which the second time interval starts to before a designated time as the timing for providing the notification. For example, the designated time may be set as a fixed time. For another example, the designated time may be set based on the motion data of the user.

Meanwhile, the processor 220 may provide the notification in various ways. According to an embodiment of the disclosure, the processor 220 may provide the notification through vibration by using at least one vibration motor. For example, the processor 220 may provide vibration at a first intensity while a posture of a part of a body of the user is a first posture. For another example, the processor 220 may provide vibration at a second intensity while the posture of the part of the body of the user is a second posture. For an example, the first posture may include a posture in which an angle of a hip joint of the user which changes according to walking of the user is a first angle. The second posture may include a posture in which the angle of the hip joint of the user which changes according to the walking of the user is a second angle.

According to an embodiment of the disclosure, the processor 220 may transmit a signal for requesting to provide the notification through the external electronic device connected with the wearable device 101 to the external electronic device. The external electronic device may provide the notification to the user based on the signal.

In operation 640, the processor 220 may identify whether a designated user input is received. For example, after providing the notification, the processor 220 may identify whether the designated user input is received based on data obtained through the at least one sensor 230 during a designated time interval.

According to an embodiment of the disclosure, after providing the notification, the processor 220 may identify the motion data of the user obtained through the at least one sensor 230 during the designated time interval. For example, after providing the notification, the processor 220 may obtain information on the moving velocity of the user during the designated time interval. For another example, after providing the notification, the processor 220 may obtain information on the stride length of the user during the designated time interval.

According to an embodiment of the disclosure, after providing the notification, the processor 220 may identify whether the motion data of the user obtained through the at least one sensor 230 during the designated time interval corresponds to reference data. After providing the notification, the processor 220 may identify whether the designated user input is received based on whether the motion data of the user obtained through the at least one sensor 230 during the designated time interval corresponds to the reference data. For example, the processor 220 may identify that the designated user input is received based on the motion data of the user corresponding to the reference data. For another example, the processor 220 may identify that the designated user input is not received, based on the motion data of the user not corresponding to the reference data.

For example, after providing the notification, the processor 220 may obtain information on the stride length of the user through the at least one sensor 230 during the designated time interval. After providing the notification, the processor 220 may identify whether an average of the stride length of the user during the designated time interval is greater than or equal to a designated stride length. The processor 220 may identify that the designated user input is received based on the average of the stride length of the user during the designated time interval being greater than or equal to the designated stride length. The processor 220 may identify that the designated user input is not received based on the average of the stride length of the user during the designated time interval being less than the designated stride length.

For another example, after providing the notification, the processor 220 may obtain information on the moving velocity of the user through the at least one sensor 230 during the designated time interval. The processor 220 may identify whether the moving velocity of the user during the designated time interval is greater than or equal to a designated moving velocity. The processor 220 may identify that the designated user input is received based on the moving velocity of the user during the designated time interval being greater than or equal to the designated moving velocity. The processor 220 may identify that the designated user input is not received based on the moving velocity of the user during the designated time interval is less than the designated moving velocity.

According to an embodiment of the disclosure, the processor 220 may provide the notification during the designated time interval. The processor 220 may identify whether the designated user input is received based on the motion data of the user obtained while the notification is provided.

In operation 650, in case that the designated user input is received, the processor 220 may change the operation mode of the wearable device 101 from the first operation mode to the second operation mode. The processor 220 may change the operation mode of the wearable device 101 from the first operation mode to the second operation mode based on identifying that the designated user input is received. For example, the second operation mode may be distinct from the first operation mode. For an example, the processor 220 may change the operation mode of the wearable device 101 from a resist 3 mode to a resist 4 mode based on identifying that the designated user input is received.

According to an embodiment of the disclosure, after changing the operation mode of the wearable device 101 from the first operation mode to the second operation mode, the processor 220 may provide another notification for guiding a motion of the user. For example, after changing the operation mode of the wearable device 101 from the first operation mode to the second operation mode, the processor 220 may provide another notification for guiding the moving velocity of the user.

In operation 660, in case that the designated user input is not received, the processor 220 may maintain the operation mode of the wearable device 101 in the first operation mode. The processor 220 may maintain the operation mode of the wearable device 101 in the first operation mode based on identifying that the designated user input is not received. For an example, the processor 220 may maintain the operation mode of the wearable device 101 set to the resist 3 mode based on identifying that the designated user input is not received.

According to an embodiment of the disclosure, in response to providing the notification, the processor 220 may identify another user input that is distinct from the designated user input from the external electronic device connected with the wearable device. The processor 220 may maintain the operation mode of the wearable device 101 in the first operation mode based on the other user input.

According to an embodiment of the disclosure, the processor 220 may identify a specific operation of the user. The processor 220 may change the operation mode of the wearable device 101 from the first operation mode to a third operation mode based on identifying the specific operation of the user. For example, the specific operation of the user may include a waist turning operation or a lunge operation.

FIG. 7A illustrates an operation of a wearable device according to an embodiment of the disclosure.

Referring to FIG. 7A, at a timing 700, a processor 220 may operate in a first operation mode. For example, in the first operation mode, the processor 220 may output torque having values within a first designated range. The processor 220 may identify that a reference time has elapsed from a timing of initiating outputting the torque having values within the first designated range. For example, the reference time may be set as an interval 701. In the interval 701, the processor 220 may identify that an operation mode of the wearable device 101 is maintained in the first operation mode. In the interval 701, the processor 220 may identify that output of the torque having values within the first designated range is maintained.

At a timing 710, the processor 220 may provide a notification based on identifying that the reference time (e.g., the interval 701) has elapsed from a timing at which the operation mode of the wearable device 101 is set to the first operation mode.

After providing the notification, the processor 220 may obtain motion data of a user during a designated time interval. For example, the designated time interval may be set as an interval 723. In the interval 723, the processor 220 may identify whether a designated user input is received based on the motion data of the user obtained through at least one sensor 230. For example, the processor 220 may wait for an operation which identifies whether the designated user input is received during an interval 712 from the timing 710 of providing the notification.

After the interval 712 has elapsed, in the interval 723, the processor 220 may identify whether the designated user input is received based on the motion data of the user obtained through the at least one sensor 230. For example, at a timing 720, the processor 220 may start an operation which identifies whether the designated user input is received based on the motion data of the user obtained through the at least one sensor 230. For example, the interval 712 may be set to a fixed time. For another example, the interval 712 may be set based on the motion data of the user.

According to an embodiment of the disclosure, the processor 220 may identify information on stride length of the user based on the motion data of the user. The processor 220 may identify the reference time (e.g., the interval 701) based on the information on the stride length of the user.

For an example, the processor 220 may identify that the user takes 0.83 seconds per step, based on the motion data of the user. The processor 220 may provide the notification prior to a time required for 10 steps from the timing 720. The processor may provide the notification 8.3 seconds prior to the timing 720. The interval 712 may be set to 8.3 seconds. The processor 220 may identify the reference time (e.g., the interval 701) by setting the interval 712.

According to an embodiment of the disclosure, the processor 220 may obtain the motion data of the user during the designated time interval immediately after providing the notification. For example, the designated time interval may be set as an interval 713.

Meanwhile, based on identifying that the designated user input is received, at a timing 730, the processor 220 may change the operation mode from a first operation mode to a second operation mode. The processor 220 may change torque within the first designated range to torque within a second designated range.

Therefore, the processor 220 may operate in the first operation mode in an interval 703. The processor 220 may output the torque having values within the first designated range in the interval 703. The processor 220 may operate in the second operation mode in an interval 734 from the timing 730 to a timing 740. The processor 220 may output torque having values within the second designated range in the interval 734.

FIG. 7A illustrates an embodiment for changing the operation mode of the wearable device 101 from the first operation mode to the second operation mode based on time, but the processor 220 may change the operation mode of the wearable device 101 from the first operation mode to the second operation mode based on the distance. A specific embodiment thereof may be described through FIG. 7B.

FIG. 7B illustrates an operation of a wearable device according to an embodiment of the disclosure.

Referring to FIG. 7B, at a point 750, a processor 220 may operate in a first operation mode. The processor 220 may output torque having values within a first designated range at the point 750. The processor 220 may identify that an operation mode of the wearable device 101 is maintained in the first operation mode in a section 756. The processor 220 may identify that output of the torque having values within the first designated range is maintained in the section 756. At a point 760, the processor 220 may provide a notification.

After providing the notification, the processor 220 may obtain motion data of a user during a designated section. For example, the designated section may be set as a section 778. The processor 220 may identify whether a designated user input is received based on the motion data of the user obtained through at least one sensor 230 in the section 778. For example, the processor 220 may wait for an operation which identifies whether the designated user input is received while the wearable device 101 moves from the point 760 that provided the notification to a point 770. The processor 220 may wait for an operation which identifies whether the designated user input is received during a section 767. The processor 220 may identify whether the designated user input is received based on the motion data of the user obtained through the at least one sensor 230 based on the wearable device 101 being located at the point 770. The processor 220 may identify whether the designated user input is received based on the motion data of the user obtained through the at least one sensor 230 during the section 778 from the point 770 to a point 780.

For example, the section 767 may be set to a fixed distance. For another example, the section 767 may be set based on the point 750 and the point 770. For an example, the section 767 may be set based on a designated ratio of a section between the point 750 and the point 770. For an example, the section 768 may be set based on a designated ratio of a section between the point 760 and the point 780. In case that the designated ratio is set to 10%, and the section between the point 750 and the point 770 is set to 2 km, the section 767 may be set to 200 m.

Meanwhile, the processor 220 may change the operation mode from the first operation mode to a second operation mode at the point 780, based on identifying that the designated user input is received. The processor 220 may change the torque having values within the first designated range to torque having values within a second designated range.

Therefore, the processor 220 may operate in the first operation mode in a section 758. The processor 220 may output the torque having values within the first designated range in the section 758. The processor 220 may operate in the second operation mode in a section 789 between the point 780 and a point 790. The processor 220 may output the torque having values within the second designated range in the section 789.

FIG. 8A illustrates an operation for providing a notification through vibration in a wearable device according to an embodiment of the disclosure.

FIG. 8B illustrates an operation for providing a notification through vibration in a wearable device according to an embodiment of the disclosure.

Referring to FIGS. 8A and 8B, an outputting circuit 250 of the wearable device 101 may include at least one vibration motor. The wearable device 101 may provide a notification to a user through vibration by using the at least one vibration motor. For example, the at least one vibration motor may include a first vibration motor 801 and a second vibration motor 802. The first vibration motor 801 may be included in the wearable device 101 to be located in front of a part of a body of the user (e.g., thigh). The second vibration motor 802 may be included in the wearable device 101 to be located on a rear side of the part of the body of the user (e.g., thigh).

According to an embodiment of the disclosure, the processor 220 may provide vibration at a first intensity while a posture of the part of the body of the user is a first posture. The processor 220 may provide vibration at a second intensity while the posture of the part of the body of the user is a second posture. For an example, the first posture may include a posture in which an angle of a hip joint of the user which changes according to walking of the user is a first angle. The second posture may include a posture in which the angle of the hip joint of the user which changes according to the walking of the user is a second angle.

Referring to FIG. 8A, the user may change the posture sequentially from a posture 811 to a posture 815 when walking. While the user is changing the posture from the posture 811 to the posture 815, the wearable device 101 may provide the notification through the first vibration motor 801. For example, the processor 220 may change an operation mode of the wearable device 101 from a first operation mode to a second operation mode. For example, the wearable device 101 may change the operation mode from the first operation mode for outputting first resist torque to the second operation mode for outputting second resist torque. The second resist torque may be set to be greater than the first resist torque. The processor 220 may provide the notification to the user through vibration for representing that magnitude of the resist torque outputted from the wearable device 101 is scheduled to increase.

For example, the processor 220 may provide vibration at the lowest intensity in the posture 811 through the first vibration motor 801. The processor 220 may provide vibration at the greatest intensity in the posture 815 through the first vibration motor 801. The processor 220 may output the intensity of the vibration strongly as the posture of the part of the body of the user is changed from the posture 811 to the posture 815. For example, the processor 220 may output the intensity of vibration outputted through the first vibration motor 801 strongly as the angle of the hip joint of the user increases. The processor 220 may output vibration through the first vibration motor 801 strongly as the part of the body of the user (e.g., thigh) moves forward.

For example, the processor 220 may provide vibration through the first vibration motor 801 located in front of the part of the body of the user and may not provide vibration through the second vibration motor 802 located on the rear of the part of the body of the user.

Referring to FIG. 8B, the user may change the posture sequentially from a posture 821 to a posture 825 when walking. While the user is changing the posture from the posture 821 to the posture 825, the wearable device 101 may provide the notification through the second vibration motor 802. For example, the processor 220 may change the operation mode of the wearable device 101 from the first operation mode to the second operation mode. For example, the wearable device 101 may change the operation mode from the first operation mode for outputting first resist torque to the second operation mode for outputting second resist torque. The second resist torque may be set to be lower than the first resist torque. The processor 220 may provide the notification to the user through vibration for representing that magnitude of the resist torque is scheduled to decrease.

For example, the processor 220 may provide vibration at the lowest intensity in the posture 821 through the second vibration motor 802. The processor 220 may provide vibration at the greatest intensity in the posture 825 through the second vibration motor 802. The processor 220 may output the intensity of the vibration strongly as the posture of the part of the body of the user is changed from the posture 821 to the posture 825. For example, the processor 220 may output the intensity of vibration outputted through the second vibration motor 802 strongly as the angle of the hip joint of the user increases. The processor 220 may output vibration through the second vibration motor 802 strongly as the part of the body of the user (e.g., thigh) moves forward.

For example, the processor 220 may provide vibration through the second vibration motor 802 located on the rear of the part of the body of the user and may not provide vibration through the first vibration motor 801 located in front of the part of the body of the user.

FIG. 9 illustrates an operation of a wearable device according to an embodiment of the disclosure.

Referring to FIG. 9, a processor 220 may establish a connection with an external electronic device 104. The external electronic device 104 may operate being worn on a part of a body of a user (e.g., an ear). The external electronic device 104 may have a shape that is detachable from each of two ears of the user. The external electronic device 104 may be used to output sound to the user.

The wearable device 101 may be moved being worn by the user during a timing 900-1 to a timing 900-2. The processor 220 of the wearable device 101 may identify information on walking of the user based on a change in a hip joint angle of the user. For example, the processor 220 may identify information on stride length or information on a posture by identifying an angle of a left hip joint and an angle of a right hip joint of the user.

At the timing 900-1, the processor 220 of the wearable device 101 may be located at a point 901. The timing 900-1 may be a timing when a reference time has elapsed from a timing when an operation mode of the wearable device 101 is set to a first operation mode. At the timing 900-1, the processor 220 may transmit, to the external electronic device 104, a signal for requesting to provide a notification through the external electronic device 104 connected to the wearable device 101. For example, the processor 220 may transmit, to the external electronic device 104, a signal for requesting to provide, through the external electronic device 104, a notification representing to perform a process for changing the operation mode of the wearable device 101 from the timing 900-2. For an example, the process for changing the operation mode may include a process for identifying whether a designated user input is received based on motion data of the user obtained through at least one sensor 230 during a designated time interval.

The processor 220 may transmit, to the external electronic device 104, a signal for requesting to provide, through the external electronic device 104, a notification representing to perform a process for changing the operation mode from a point 902 (or the timing 900-2).

In response to receiving the signal, the external electronic device 104 may provide the notification representing that the process for changing the operation mode will be performed to the user through sound. For example, the external electronic device 104 may provide, to the user, through sound, a notification representing that a process for changing the operation mode will be performed 10 m ahead. For another example, the external electronic device 104 may provide, to the user, through sound, a notification representing that a process for changing the operation mode will be performed after 10 seconds.

According to an embodiment of the disclosure, the processor 220 may provide music or a step sound according to the stride length of the user during the timing 900-1 to the timing 900-2. According to an embodiment of the disclosure, during the timing 900-1 to the timing 900-2, the processor 220 may provide the notification through a voice, such as “There are 10 steps left until the section to change the exercise intensity.”

At the timing 900-2 to a timing 900-3, the processor 220 may identify whether the designated user input is received based on the motion data of the user obtained through the at least one sensor 230. While the wearable device 101 moves from the point 902 to a point 903, the processor 220 may identify whether the designated user input is received based on the motion data of the user obtained through the at least one sensor 230.

At the timing 900-2 or the point 902, the processor 220 may provide a notification for receiving the user input through the external electronic device 104. For example, at the timing 900-2, the processor 220 may provide the notification through a voice, such as “In a case of walking fast for 10 seconds, the exercise intensity increases.” At the timing 900-2 to the timing 900-3, the processor 220 may provide a sound for representing whether the operation mode is changed to the user through the external electronic device 104.

At the timing 900-3 or the point 903, the processor 220 may provide a notification for representing whether the user input is received through the external electronic device 104.

For example, the processor 220 may provide a notification through a voice, such as “A request to change the exercise intensity is detected. The exercise intensity will change in a moment.” After providing the notification, the processor 220 may change the operation mode of the wearable device 101 from a first operation mode to a second operation mode.

For another example, the processor 220 may provide a notification through a voice, such as “A request to stop changing the exercise intensity is detected. The current exercise intensity will be maintained.” After providing the notification, the processor 220 may maintain the operation mode of the wearable device 101 in the first operation mode.

FIG. 10 illustrates an operation of a wearable device according to an embodiment of the disclosure.

Referring to FIG. 10, a processor 220 may establish a connection with an external electronic device 105. The external electronic device 105 may operate being worn on a part of a body of a user (e.g., face). The external electronic device 105 may have a shape of glasses. The external electronic device 105 may be used to provide a visual object overlaid on a visible environment.

The processor 220 of the wearable device 101 may transmit a visual object 1010 and information for representing a visual object 1020 to the external electronic device 105. For example, the processor 220 may transmit information on a location where an operation mode of the wearable device 101 is to be changed and information on a section for performing a process for changing the operation mode to the external electronic device 105. For an example, the process for changing the operation mode may include a process for identifying whether a designated user input is received based on motion data of the user obtained through at least one sensor 230 for a designated distance.

For example, the processor 220 may identify a location where the operation mode of the wearable device 101 will be changed from a first operation mode to a second operation mode based on information on stride length of the user and a reference time.
