The Xperia Touch projector can turn any flat surface into a 23-inch high-definition touchscreen. It's able to detect movement corresponding to clicks and swipes, using a combination of infrared light and its built-in camera.

Launched at last week's Mobile World Congress, the concept was first unveiled at SXSW, but it looks like it might be available to consumers as early as spring this year.
