The Puyocon mouse is shown off at SIGGRAPH Asia 2009 by students at the University of Tsukuba. Unlike other mid-air input devices, the Puyocon is meant to be thrown either as an input gesture, or for passing from one to another. With 14 pressure sensors in it, it is able to capture with reasonable detail the movement of the ball. It is a bit difficult to imagine it working well with Powerpoint, it may prove very fun in combination with party games in which people toss it to each other. For more visit the Puyocon website.

Hard at work, TAT (The Astonishing Tribe) demonstrated its 3D Eye UI at Mobile World Congress 2009. The prototype system demonstrates the use of eyetracking to simulate 3D windows layers by manipulating the UI layers based on the positioning of the screen relative to the person looking at it. To see the method explained, check out Jonny Lee‘s 3D head tracking using the Wiimote.

TAT (The Astonishing Tribe) demonstrates its Foldout UI at Mobile World Congress 2009. Utilizing a physics engine, the screen content reacts as the user flings content around the screen reminiscent to the game Little Big Planet on the Sony PlayStation.

viZoo demonstrates Cheoptics360, a volumetric display device able to show 3D objects and video at any angle.

Researchers from the University of Toronto use a Perspecta 3D volumetric display to create a set of finger gestures to interact with objects in a 3D space.
