- the control module 130 may determine the wearing state of the wearable device 100 by analyzing sensor data from the sensor obtained after the test torque is transmitted to the leg drive frame.
- the sensor data may include movement information of each component of the wearable device 100 (eg, a first leg driving frame, a second leg driving frame, and a waist support frame) corresponding to the shaking motion.
- the sensor data obtained when the shaking motion of the leg driving frame occurs includes a change in movement of the leg driving frame (corresponding to a change in movement of the user 110). ) will be absent or appear in small amounts. If the user 110 is not wearing the wearable device 100 or is not wearing it correctly, a significant change in the movement of the leg driving frame will appear in the sensor data obtained when the shaking motion of the leg driving frame occurs.
- the control module 130 may determine whether the wearable device 100 is normally worn on the body of the user 110 based on the degree of movement change indicated in the sensor data. If it is determined that the device is in a normal worn state, the test may be determined to have passed, and if it is determined that the device is not in a normal worn state, it may be determined that the test has not passed.
- determining that the wearable device 100 is normally worn on the body of the user 110 may indicate that the wearable device 100 is properly worn on the body of the user 110. there is. Determination that the wearable device 100 is not properly worn on the body of the user 110 means that the wearable device 100 is not worn on the body of the user 110 at all or is worn properly on the body of the user 110. It can include anything that is not in a state.
- the control module 130 may drive the wearable device 100 when it is determined that the wearable device 100 is normally worn on the body of the user 110, and the wearable device 100 may operate the user ( If it is determined that the wearable device 110 is not properly worn on the body, the wearable device 100 may not be driven, or the wearable device 100 may be stopped from operating. In one embodiment, when the control module 130 determines that the wearable device 100 is not properly worn on the user 110's body, the control module 130 provides a guide notification to the user 110 so that the user 110 can use the wearable device ( 100) can be encouraged to wear it correctly.
- the guide notification may be provided to the user 110 in the form of a voice guide output from the wearable device 100 or a notification message output on an electronic device that works with the wearable device 100.
- the wearable device 100 prevents the wearable device 100 from moving or moves when the wearable device 100 is not properly worn on the body of the user 110. By reducing it, the possibility of the user 110 being injured as mentioned above can be reduced.
- the wearable device 100 can actively move the leg driving frame through test torque, and determines whether the user 110 has properly worn the wearable device 110 based on the degree of movement of the leg driving frame shown in the sensor data. By making this decision, it is possible to effectively test for normal wear without connecting hardware components to the fastener.
- FIG. 2 is a diagram illustrating a management system including a wearable device and an electronic device according to an embodiment.
