There are a number of different designs that use infrared and ultraviolet lights to create a custom multi-touch screen. The resulting tool allows you to interface with your computer or any other device using just your fingertips. You can increase such a touch-screen’s energy efficiency and keep costs down using UV LED lighting and infrared LED lighting. IR and UV LED lamps emit light in the near-infrared and ultraviolet light frequencies at a fraction of the energy cost of incandescents, have a lifetime roughly five times as long, and can be easily integrated into a homemade multi-touch screen.
