clouseau rueful: Tobii EyeAsteroids 3D lets you destroy virtual space stones with a gaze, we go eyes-on (video)

We've touched and tapped our way through a variety of gadgets at CeBIT, but it's the devices that operate without traditional user interfaces that have really grabbed our focus. Tobii was on-hand to demonstrate its eye-tracking technology earlier this year at CES, but the company is peddling its wares here in Hannover as well, and we decided to drop by for a second look. This time, it's all about gaming, with EyeAsteroids drawing quite a bit of attention on the show floor. The demo pairs Tobii with a SeeFront glasses-free 3D panel for a fairly engaging extraterrestrial shootout. We weren't really sold on the glasses-free 3D, unfortunately, which provides the same unconvincing three-dimensional image from any angle, but Tobii was spot-on, letting us hone in on those infamous space rocks to save our planet from destruction without even raising a finger.

Like SeeFront's display, you're able to make visual selections from any angle (within reason) just as easily as you can from directly in front of the panel. There's a seconds-long calibration process each time you start the game, so Tobii can locate your eyes and pair your pupil orientation with a target on the screen. After that, it's open season -- you simply focus on an asteroid to destroy it, and you can add your name to the leader board and navigate menus as well, just as we saw with the Windows 8 demo back at CES. Is this the future of gaming? That remains to be seen, and while the eye-tracking seemed to work just as described, old school gamers will likely prefer tilting a joystick and (violently) tapping on arcade buttons. We still had a lot of fun playing without using our hands, though, as you'll see in our glare-filled demo just past the break.
