Patent ID: 8897488

Claim:
A body gesture control system for operating electrical and electronic devices, comprising: an image sensor device sequentially capturing and generating at least two body gesture images of a user in the form of image data, with the at least two body gesture images including at least two body part gesture images or at least two eye gesture images; and an image processor device in communication with the image sensor device and receiving the image data, with the image processor device processing the at least two body gesture images for recognizing body gestures, with the image processor device including: an image calculation unit calculating gesture regions of the at least two body gesture images; and a gesture change detection unit electrically connected with the image calculation unit, with the gesture change detection unit detecting changes of the at least two body gesture images and to thereby determine a body gesture recognition signal; wherein the gesture change detection unit calculates at least one displacement of the body gestures from a first position region between (x 0 , y 0 ) and (x 1 , y 1 ) shown in a first image frame of the at least two body gesture images captured at a first time (T 0 ) to a second position region between (x 2 , y 2 ) and (x 3 , y 3 ) shown in a second image frame captured at a second time (T 1 ) of the at least two body gesture images with the first and second position regions being different, with the first and second times (T 0 , T 1 ) being different; and wherein the gesture change detection unit further calculates a differential between the first position region of the first image frame and the second position region of the second image frame of the at least two body gesture images and receiving a change of the gesture regions as the at least one displacement of the body gestures.
