Controlling applications with hand gestures is a more natural way to communicate with computers, according to a team of engineering students at Northeastern University. With a PC interface developed by the team, users move a hand back and forth or up and down over several rows of copper plates to communicate with a computer. The "electric-field sensing device" locks on to the static electricity of the user. The team has created an "interactive space" in which communication occurs without the user wearing sensors. The copper plates track the hand movements, then pass the coordinates through circuitry that is attached to a PC via a USB port. The team used the device to control a three-dimensional model on a computer screen in a video demonstration.
