Claim One:
1. A method of distinguishing meaningful gestures from proximate non-meaningful gestures in a three-dimensional (3D) sensory space, the method including: distinguishing wrist and finger flexing from an overall trajectory of an arm gesture while the arm is in motion, including: detecting positions of the arm and attached wrist and fingers in a three dimensional (3D) sensory space using an electronic sensor; calculating from a series of the detected positions a spatial trajectory of a waving gesture executed by the arm; calculating from the detected positions spatial trajectories of the flexing gestures of the wrist and/or fingers; and determining whether the waving gesture or the flexing gestures dominate based on magnitudes of the respective spatial trajectories; and triggering a response to the dominant gesture without triggering a response to the non-dominant gesture.
