Learning Touch Gestures using HMM on Tabletop Display
검색

    초록·키워드

    In this paper, we propose a learning algorithm of touch gesture using HMM for tabletop display. Touch gestures are classified into the two groups that are the single and multi stroke gestures according to the number of strokes. The input images which are obtained by a video camera include the strokes. The chain code can be utilized to represent the gesture stroke with the directional codes as feature vector. In this algorithm we use ten gestures and the feature of each gesture is represented as one hundred directional codes. We have defined the gestures to be shaped independently among others, and they can be recognized by the comparison with the previously trained model. For the definition of new gesture which is not defined at the first learning time we give the meaning of the gesture and then apply the learning algorithm to expand the recognition range. We have implemented a real-time gesture recognition system on the tabletop display. The experimental result shows the robustness of the gesture recognition system.
