6. The method of claim 5 , wherein applying the motion-assisted gesture recognition process to the plurality of the video frames of the visual gesture comprises: detecting motion of the object contained in the plurality of video frames capturing the visual gesture, the object being bounded in the ROI of a video frame of the plurality of video frames of the video; and recognizing the visual gesture based at least in part on the detected motion of the object.
