For example, the wearable device 110 may initialize the hip joint angle value output from the angle sensor and the upper body movement value output from the inertial measurement device. In one embodiment, before the start of the SPPB test, the electronic device 210 may provide the user with a guide explaining how to set up a test for the SPPB test and the actions the user should take while wearing the wearable device 110.

When the countdown of the preparation time is completed, the electronic device 210 may inform the user of the start of the SPPB test and activate a timer to measure the time.

The electronic device 210 may record leg movements for a preset time. The electronic device 210 may evaluate the user's exercise ability based on leg movement. The electronic device 210 may estimate the degree of movement of the leg based on the hip joint angle value and may estimate the degree of movement of the upper body based on the upper body movement value. The electronic device 210 may determine that the user's leg has moved when the hip joint angle value measured for one time period (eg, 10 seconds) is greater than or equal to the first threshold. The electronic device 210 may determine that the user's upper body has moved when the movement value of the user's upper body measured during one hour period is greater than or equal to the second threshold.

In one embodiment, the electronic device 210 determines the user's motor ability (e.g., balance) based on the user's posture subject to the SPPB test, the upper body movement value measured during a one-hour period, and the time it is determined that the leg was moved. ) can be estimated. The electronic device 210 may assign different scores according to the user's posture, upper body movement value, and leg movement time, and determine the final score for the user's SPPB test based on the scores of each evaluation factor. there is. For example, the electronic device 210 may assign a relatively low score if the degree of movement of the upper body and/or the degree of leg movement is large during the SPPB test process. Additionally, the electronic device 210 may assign a lower score the faster the user moves his legs.

In one embodiment, the electronic device 210 may calculate a score related to the evaluation of the user's exercise ability based on evaluation criteria for evaluating the user's exercise ability through the SPPB test. The degree of upper body movement may be determined based on, for example, upper body movement values and/or hip joint angle values.

In one embodiment, the user 110 may perform a TUG test using the wearable device 100 and the electronic device 210. The electronic device 210 may receive a user input for proceeding with the TUG test, and in response to the user input, the electronic device 210 may instruct the wearable device 100 to activate an exercise ability evaluation mode for proceeding with the TUG test. You can request it. A chair to sit on for the TUG test may be prepared and a certain distance from the chair may be marked. In the TUG test, when the test is started while the user 110 is wearing the wearable device 100 and sitting on a chair, the user 110 gets up from the chair, travels a certain distance, and then sits down on the chair again. Time can be measured. The wearable device 100 may acquire sensor data by measuring the degree of movement of the user 110 during the test time. For example, the sensor data may include walking movement information about the movement of the user 110 while walking while wearing the wearable device 100. The wearable device 100 may transmit sensor data acquired during the test time to the electronic device 210, and the electronic device 210 estimates information about the TUG test based on the sensor data received from the wearable device 100. can do.

The electronic device 210 may count down the preparation time for the TUG test, and the wearable device 110 may initialize the hip joint angle value output from the angle sensor during the preparation time. For example, the wearable device 110 may set the hip joint angle value output from the angle sensor to 0 during the preparation time. In one embodiment, before the start of the TUG test, the electronic device 210 informs the user of the supplies for the TUG test (e.g., chair, tape measure), how to set up the test, and what actions the user should take while wearing the wearable device 110. An explanatory guide can be provided.

When the countdown of the preparation time is completed, the electronic device 210 may inform the user of the start of the TUG test and activate a timer to measure the time. When the user moves the body according to the TUG test method, the wearable device 100 may acquire the hip joint angle value through the sensor module and transmit the acquired hip joint angle value to the electronic device 210. The electronic device 210 may determine whether the hip joint angle value is greater than the first threshold value. If the hip joint angle value is greater than the first threshold value, the electronic device 210 may recognize that the user has stood up from the chair, and accordingly change the user's operating state value to the first state value.

Afterwards, the electronic device 210 may determine whether the hip joint angle value is smaller than the second threshold value. Here, the second threshold value may be different from the first threshold value. For example, the second threshold may be smaller than the first threshold. If the hip joint angle value is less than the second threshold value, the electronic device 210 may recognize that the user has sat down on the chair again, and may change the user's operating state value to the second state value accordingly.

The electronic device 210 may change the operating state value to the third state value after a predefined time (eg, 2 seconds) has elapsed. Here, the first state value, the second state value, and the third state value may be different state values.

In one embodiment, for the above TUG test, the hip joint angle value corresponding to the right leg, the hip joint angle value corresponding to the left leg, or the average value of the hip joint angle value corresponding to the right leg and the hip joint angle value corresponding to the left leg are used. It can be used. In one embodiment, the electronic device 210 may perform the TUG test based on the hip joint angle value obtained by filtering the hip joint angle value.
