But the company which was one of the first to get a projector equipped phone on the market- LG- is already thinking about new ways to operate the device. One of the possibilities to do that is described in LG patent application, called “Mobile terminal with image projection”. It describes the way to remotely sense gestures/touch that user performs on a projected image.
The idea is simple – identify a pointer (your finger), the shadow a pointer makes on a projected image, a distance between them, and track this distance. When you touch something on the projected image, distance decreases and touch event is registered. Move your finger across the projection and swype gesture is registered, etc;
It does require some hefty processing power and software magic. But if/when pico-projector in your smartphone becomes good enough for it to become your portable presentation device, I can see how such a remote touch operation capability could be a really nice bonus.
