Augmented reality demonstrations may be pretty common these days, but this so-called "Twinkle" interface developed by some researchers Tokyo University and Keio University takes a different enough approach to still turn a few heads. That's done thanks to the combination of a pico projector and a camera, the former of which projects a character onto any surface, while the latter is used along with some image processing software to identify objects the character can interact with. That's further backed up by an accelerometer that detects movements the camera can't, and the researchers say that the system can not only recognize specific objects like the ones on the board p
