PlayStation motion controller (2010)

Announced and demonstrated at this year's E3 game show in Los Angeles, Sony's PlayStation motion controller is in many ways a "me too" product to the motion-tracking capabilities of Nintendo's Wii remote. But Sony adds several new features.

For one, the controller mixes internal sensors with Sony's Eye camera to track movement, which Sony says will make the device more accurate when it comes to things like twisting and back-and-forth movement. It also employs a colored ball on top of the controller that offers developers an opportunity to program an extra layer of interactivity into their games.

We still don't know which games will work with Eye out of the gate, how much it will cost, or what the final design will be. But if you want to see how it performs in a live demo, you can watch this video.
