There exits high computational complexity and time complexity on accelerometer-based gesture recognition. This paper proposed a gesture NMF features extraction and recognition scheme based on acceleration tracks. First of all,it captured the gesture acceleration data by a Wiimote controller,after real-time gesture segmentation by using the gesture segmentation algorithm based on slope threshold and error threshold of fitting lines,and transformed the gesture acceleration data into gesture track images,it used non-negative matrix factorization for extracting feature vectors,and used discrete hi...
