University researchers have developed an interface between a mobile camera phone, Bluetooth and a video display. It allows the user to control the cursor on the screen. A crude prototype at the moment, but it has great promise if you imagine a crowd in a bar or an event or on the high street playing games via a large video display or projection. Turn your phone into a Wii-style remote!

The system was developed by three guys at British universities. Nick Pears researches Computer Vision, Pattern Recognition and Robotics in the Advanced Computer Architectures Group at York University whilst Patrick Oliver and Dan Jackson are at Newcastle University.
