I’m still mulling over everything I saw at the Consumer Electronics Show, but I know what my sleeper hit is: Sixense’s TrueMotion game controller, which I saw demoed at the meeting room of chipmaker Analog Devices, which supplies some of the technology the controller uses. It looks very much like Nintendo’s Wiimote and the basic idea is the same. But TrueMotion uses a base station that creates an electromagnetic field to provide much, much, much more precision than the Wiiremote. It doesn’t just know the general direction you’ve moved the remote–it can tell exactly where it is and what angle you’re holding it at. End result: You can manipulate on-screen objects in a way that feels dramatically more real than on the Wii.

I could go on, but Sixense’s video demo shows this better than I can explain it–although TrueMotion is even more impressive when you try it yourself than it is in this clip:

Sixense says that TrueMotion will work with existing games as well as ones designed specifically to take advantage of its capabilities. It expects TrueMotion-based controllers for PCs to ship by Christmas, one controller and base station bundled with a game will go for under $100.
