Abstract

A motion evaluation system, a method thereof and a computer-readable recording medium are provided. The motion evaluation system includes at least one sensor and a processor. The sensor generates sensing data for a motion posture. The processor obtains the motion posture of the sensor, determines a continued time accumulated when the motion posture conforms to a correct posture, and sends a notification message according to the continued time. The correct posture is related to an angle at which a portion under test inclined to a reference object. Accordingly, the rehabilitation can be performed anytime and anywhere, and it is easier for tracking the rehabilitation situation.

Claims

1. A motion evaluation system, comprising:

at least one sensor, configured to generate sensing data for a motion posture; and

a processor, configured to obtain the sensing data of the at least one sensor, determining a continued time accumulated when the motion posture conforms to a correct posture according to the sensing data, and sending a notification message according to the continued time, wherein the correct posture is related to an angle at which a portion under test inclined to a reference object.

2. The motion evaluation system as claimed in claim 1, wherein

the processor determines whether the continued time when the motion posture conforms to the correct posture reaches a continued threshold value, and

the processor generates the notification message related to posture fulfillment in response to that the continued time reaches the continued threshold value.

3. The motion evaluation system as claimed in claim 2, wherein

the processor determines whether the motion posture returns to the correct posture within a buffer time in response to that the continued time does not reach the continued threshold value,

the processor determines whether the continued time when the motion posture conforms to the correct posture reaches the continued threshold value in response to that the motion posture returns to the correct posture within the buffer time, and

the processor generates the notification message related to posture unfulfillment in response to that the motion posture does not return to the correct posture within the buffer time.

4. The motion evaluation system as claimed in claim 3, wherein

the processor stops accumulating the continued time in response to that the continued time does not reach the continued threshold value, and

the processor re-accumulates the continued time in response to that the motion posture returns to the correct posture within the buffer time.

5. The motion evaluation system as claimed in claim 3, wherein

the processor generates the notification message related to posture unfulfillment in response to that the motion posture does not fulfill a minimum required posture, wherein an angle corresponding to the minimum required posture is less than an angle corresponding to the correct posture.

6. The motion evaluation system as claimed in claim 1, wherein

the processor generates the notification message related to posture unfulfillment in response to that the motion posture does not conform to the correct posture within a stage time.

7. The motion evaluation system as claimed in claim 1, wherein

the processor determines whether the motion posture conforms to the correct posture,

the processor determines whether a next motion gesture conforms to a second correct posture in response to that the motion posture conforms to the correct posture, and

the processor continues to confirm whether the next motion posture conforms to the correct posture in response to that the motion posture does not conform to the correct posture.

8. The motion evaluation system as claimed in claim 1, further comprising:

a display, coupled to the processor, wherein the processor displays a simulated person on the display, and the processor controls a posture of the simulated person according to the sensing data, so that the posture conforms to the motion posture.

9. A motion evaluation method, comprising:

obtaining sensing data, wherein the sensing data is provided for a motion posture;

determining a continued time accumulated when the motion posture conforms to a correct posture according to the sensing data, wherein the correct posture is related to an angle at which a portion under test inclined to a reference object; and

sending a notification message according to the continued time.

10. The motion evaluation method as claimed in claim 9, wherein the step of determining the continued time accumulated when the motion posture conforms to the correct posture according to the sensing data comprises:

determining whether the continued time when the motion posture conforms to the correct posture reaches a continued threshold value, and

generating the notification message related to posture fulfillment in response to that the continued time reaches the continued threshold value.

11. The motion evaluation method as claimed in claim 10, wherein the step of determining the continued time accumulated when the motion posture conforms to the correct posture according to the sensing data comprises:

determining whether the motion posture returns to the correct posture within a buffer time in response to that the continued time does not reach the continued threshold value;

determining whether the continued time when the motion posture conforms to the correct posture reaches the continued threshold value in response to that the motion posture returns to the correct posture within the buffer time; and

generating the notification message related to posture unfulfillment in response to that the motion posture does not return to the correct posture within the buffer time.

12. The motion evaluation method as claimed in claim 11, wherein the step of determining the continued time accumulated when the motion posture conforms to the correct posture according to the sensing data comprises:

stopping accumulating the continued time in response to that the continued time does not reach the continued threshold value; and

re-accumulating the continued time in response to that the motion posture returns to the correct posture within the buffer time.

13. The motion evaluation method as claimed in claim 11, wherein the step of determining whether the motion posture returns to the correct posture within the buffer time comprises:

generating the notification message related to posture unfulfillment in response to that the motion posture does not fulfill a minimum required posture, wherein an angle corresponding to the minimum required posture is less than an angle corresponding to the correct posture.

14. The motion evaluation method as claimed in claim 9, wherein the step of determining the continued time accumulated when the motion posture conforms to the correct posture according to the sensing data comprises:

generating the notification message related to posture unfulfillment in response to that the motion posture does not conform to the correct posture within a stage time.

15. The motion evaluation method as claimed in claim 9, wherein the step after the sensing data is obtained further comprises:

determining whether the motion posture conforms to the correct posture;

determining whether a next motion gesture conforms to a second correct posture in response to that the motion posture conforms to the correct posture; and

continuously confirming whether the next motion posture conforms to the correct posture in response to that the motion posture does not conform to the correct posture.

16. The motion evaluation method as claimed in claim 9, wherein the step after the sensing data is obtained further comprises:

displaying a simulated person; and

controlling a posture of the simulated person according to the sensing data, so that the posture conforms to the motion posture.

17. A non-transitory computer-readable recording medium, recording a computer code, loading and performing the following steps through a processor:

obtaining sensing data, wherein the sensing data is provided for a motion posture;

determining a continued time accumulated when the motion posture conforms to a correct posture according to the sensing data, wherein the correct posture is related to an angle at which a portion under test inclined to a reference object; and
