Let's think for a moment that your computer doesn't have a mouse, nor a touchpad. We'd all be typing in shortcuts, I guess. The mouse serves a purpose for now. We are addicted to the mouse. But in the future we may no longer need these little critters. Introducing: TrackIR, the Head Motion Tracker.

The TrackIR tracks the users head motions through 6 degrees of 3 dimensional movement. It supports 60 games (primarily flight and racing sims) like EVE Online, Colin McRae Rally, Flight Simulator X. An infrared cam sits on top of the monitor, capturing 120 images a second. It then processes this info to the computer via usb.

Naturally, you still need your other controller so to do the job. It's extremely easy to use, but it might take you around two days to tweak it to the way you want. Different strokes for different gamers, eh? There's a lot of ways you could customize the sensitivity of this add-on. It may offer a large advantage when participating in online dogfights, but hey it's a war out there. Try to get as much legal advantage as you can.

As for the future, they're planning to make it a bit more smaller and lighter. They're also finding out ways to use it in other genres like MMORPG, RTS, and puzzles. Sony's Eyetoy and the Xbox360 Vision Camera aren't really competitors as their gesture games aren't that advanced yet. So will you get this for your racing sim? If it makes gaming that more realistic, why not? The price? MSRP at $179.95, sold online now.
