Imagine turning any flat surface into a touch screen – well, this is now possible with Light Blue Optics’ Light Touch system. It is essentially a mini-projector that projects a virtual 10-inch (25cm) touch screen onto a surface. Using an infra-red touch sensing system, the device is able to detect where the user is “touching” the image. With both WiFi and Bluetooth connectivity, it can be used for almost any purpose where a control panel is needed. Turn your coffee table into a TV remote control, anyone?
