Our templatematching-based method using hand textures reduces background effect and enables markerless tracking. In addition, use of a high-frame-rate camera enables recognition of rapid typing motion which is difficult to track using standard cameras. In order to realize realtime recognition, we developed hardware which parallelizes and accelerates image processing. As a result, we achieved real-time recognition of typing motion wi...
