Roland Piquepaille writes "In recent years, we've started to use our cellphones not only for placing calls or exchanging messages. Now, we take pictures, read our e-mails, listen to music or watch TV. But, according to New Scientist, UK researchers are going further with a prototype software that turns your cellphone into a 3-D mouse. The phone is connected to your computer via Bluetooth. And you control the image on the screen by rotating or moving your phone. As says one of the researchers, 'it feels like a much more natural way to interact and exchange data.' The technology might first be used in shopping malls to buy movie tickets or to interact with advertising displays."
