Think touch screen cell phones are cool? Well it seems Samsung wants to take things to the next level by allowing users to "gesture" to their cell phones with hand signals. Now that's cool! According to the patent filing abstract:

The input method of the present invention includes collecting a plurality of images; storing the images as control images; mapping the control images to corresponding control commands; capturing an image taken by a camera as a current image; comparing the current image to the control images; selecting one of the control images as a target control image according to a comparison result; extracting a control command mapped to the target control image; and executing the control command." |
