Pico projectors are great, and if you're fan of pico projectors and smartphones, you'll probably be interested in the latest concept that allows you to use pico projector for interactive phone calls.

Researches from University of Duisburg-Essen, Germany, have designed a new concept that combines smartphones and pico projectors, allowing you to make interactive phone calls and share data while on the phone. During the call, pico projector projects picture onto the surface and one side of the projected image represents your phone's interface, while the other side belongs to the person you're talking to. What makes this concept so special is the ability to share data simply by dragging and dropping files onto each other's screens, and in order to make this process as simple as possible, both screens are updated in real time, so you can see changes instantly.

Although this concept looks amazing, the pico projector that is used looks rather bulky, but we hope that folks behind this project will find a way to make this device slimmer in the future.
