There’s a company in Oregon that is trying to eliminate the mouse as we know it. The company is called Naturalpoint. Basically, you place a reflective dot on your forehead or, for laptop users, a plastic ring on your finger. Then when you move your head or your finger, the mouse goes where you point. The demo on the news showed a gamer making the game look where he looked, allowing him to keep both hands on the keyboard.



TrackIR has 2 basic parts that make it work. The first is a camera that mounts on the top of your computer and second part is silver dots which you stick on your forehead, hat, etc… that catch the attention of the camera so that the cursor moves along to the movements your head makes. The dots have a cloth backing so you can stick it and remove it many times. The camera is sensitive enough to detect the silver dots and it will only detect those dots and calculate how it moves and translate it to cursor movements. So when the dots are on your head and you move your head left, the camera sees the dot moving to the left and therefore the cursor moves left.
