The Invisible Iphone

Researchers in Germany are now working on a system that would let you perform such actions without even holding the Iphone. Instead of tapping the Iphone you would tap your palm to control the Iphone. The movements then transfer from the imaginary Iphone to your real phone. This is all made possible by a headband with a camera attached to monitor your movements. The camera "subtracts" the background and tracks the finger position on the palm. It works well in various lighting conditions, including direct sunlight. Software interprets finger positions and movements to the position of icons on a person's iPhone.
