Sažetak
The paper demonstrates the feasibility of using mobile phones for fitness and rehabilitation purposes by training them to recognize a user's hula-hooping movements. It also proposes several parameters which can be used as a measure of rhythmic movement quality. Experimental measurements were achieved with two test subjects performing two sets of steady hula-hooping. The paper compares algorithm performance with accelerometer, gyroscope and magnetometer sensor readings. Analysis of the recorded data indicated that accelerometer data was unreliable, while magnetometer data was well-suited to the intended application. Hilbert transforms were used to extract the phase information, and a Dynamic Rhythmic Primitive Model was identified ed for the hula-hooping movement. Together these tools allow the creation of hula-hooping performance metrics which can be used in wellness, rehabilitation or entertainment applications for mobile devices. We outline open technical challenges and possible future research directions.
