Rob Wray, from mp3Car, takes a look at Carnegie Mellon University's "quality of life technology research center." A facial recognition technology is able to zoom in on your cursor depending on how far away your face is from the screen. Another device is able to use the sound of your finger to determine what motion your finger is making and this, in turn, dictates what the cursor on your screen does. Future applications could include combining this technology with a spacial recognition technology to give the user a very precise method of input control with no touch pad or mouse.
