Gyration’s wireless gyroscopic mouse designed specifically for use with Windows XP Media Center PCs is finally out. The Gyration Media Center Remote Control has a built-in motion detector (hence the gyroscope) so it can control the mouse pointer just by being waved around in the air. We’ve been using one with our new Media Center PC, and besides being able to use it while sitting on the couch, the Gyration Media Center Remote can also do a few other nice things like let you raise or lower the volume of whatever you’re watching or listening to just by moving your hand up or down.
