Abstract: A method for computer vision based hand gesture device control, is provided. The method includes receiving a sequence of images of a field of view; applying a shape recognition algorithm on the sequence of images to detect a shape of a first posture of a hand; and generating a command to initiate device control based on the detection of the shape of the first posture of the hand.

Abstract: A system and method are provided for controlling a device based on computer vision. Embodiments of the system and method of the invention are based on receiving a sequence of images of a field of view; detecting movement of at least one object in the images; applying a shape recognition algorithm on the at least one moving object; confirming that the object is a user hand by combining information from at least two images of the object; and tracking the object to control the device.

Abstract: In the invention two consecutive movement paths are detected and displayed content may be manipulated based on the detection of the first movement path of the hand but once a first movement and a second movement path are detected manipulation of the displayed content by the second movement is prevented. Thus, detection of a pair of movement paths prevents unintentional activation of a device.
