I find this notice, and I think that this invention is possible and very very important, because there are a lot of people with mobility and sensitive problems, and because that, every advance is a good new!
The invention:
The SixthSense is a wearable gestural interface that lets natural hand gestures interact with digital information. In other words, it's the computer interface that you have watching in every science fiction film made in the last ten years. Imagine a watch appearing on your wrist when you tap on it, or a phone call being placed after tapping out a phone number on the palm of your hand. Still a prototype, the SixthSense's hardware components are coupled in a wearable device with a projector and a camera connected to the computer. The projector projects visual information enabling surfaces, walls and objects to be used as computer interfaces; while the camera tracks the user's hand gestures using computer-vision based techniques.
