ROBUST VIDEO-BASED HANDWRITING AND GESTURE RECOGNITION FOR IN-CAR APPLICATIONS

摘要

A method of receiving input from a user includes sensing a first trajectory of a center of mass of a hand of the user during a gesture made by the hand. A second trajectory of a finger tip of the hand of the user during the gesture made by the hand is also sensed. An alphanumeric character represented by the gesture made by the hand is determined dependent upon both the first trajectory and the second trajectory.
