Gesture Identification In An Individual With Crossed Aphasia: A Case Study

The threshold range is decided from distance matrix of live samples of hand so that the vary doesn’t turn out to be too high or too small which could increase false detection chance. To identify the ‘Drive’ mode gesture, it is noticed that, only the apex of the index finger (keypoint 8) maintains a larger distance from the wrist of the hand (keypoint 0), whereas the other keypoints of the fingertips stay near the wrist. For this gesture, also a threshold range is used which made the proposed model extra environment friendly and flexible for the disabled folks. If the distance between keypiont zero and keypoint eight falls in a specific vary of threshold and all different distances are less than one other threshold, then ‘Drive’ gesture is detected. If any disabled individual cannot stretch his index finger absolutely, he or she may even able to operate this method as a result of considering range of thresholds. During making use of the range value additionally it is thought of that it shouldn't be too much flexible which may make the system confused and detect the gestures wrongly.
