The game of Anti-Tetris is played by standing in front of a monitor and watch falling Tetris pieces overlaid on a video image of your body. Each hand is used to make pieces disappear so that they don’t stack up to the top of the screen. We don’t see this as the next big indie game. What we do see are some very interesting techniques for hand tracking. An FPGA drives the game , using a camera as input. To track your hands the Cornell students figured out that YUV images show a specific range of skin tones which can be coded as a filter to direct cursor placement. But they needed a bit of a hack to get at those values. They patched into the camera circuit before the YUV is converted to RGB for the NTSC output. Registering hand movement perpendicular to the screen is also a challenge that they faced. Because the hand location has already been established they were able to mea...
