Outline of Final Research Achievements |
In this research, a system to recognize ankle motions and to model a Sit-to-Stand motion using ankle EMG signals is developed for power-support devices. First, three motions of ankle, neutral, doesiflexion and plantar flexion using ankle EMG signals are recognized and 95% high accuracy is obtained for on-line experiments. Next, the Sit-to-Stand motion including three motions of ankle is recognized. The Sit-to-Stand motion is then divided into three motions. As a result, 62% accuracy is obtained and it is worse than that of three ankle motions. And also data distribution analysis in eigenspace showed that EMG data of Sit-to-Stand motion and that of three ankle motions measured at ankle are different. In the future, accuracy improvement including a normalization method for ankle EMG data for the Sit-to-Stand motion is needed.
