Abstract
Precise analysis and description of movement and gestures by a human or other object are carried out by a computing device assisted by camera and distance sensors. The same gestures and movements of an object in different locations and in different orientations may be identified according to coordinates and offsets applied to coordinates, and gesture-making areas projected so as to surround the object. The techniques can accurately identify actions of movements of the human or other object.
