After years of ergonomically incorrect computer use, many people suffer from a tennis-elbow-like condition sometimes called "mouse arm," causing pain in the wrist and forearm. One solution is a gyroscopic mouse, held in the hand like a remote control, which is a much more natural position for the wrist. A company called Gyration has carved out a unique niche with its line of gyroscopic input devices. The tiny $199 Gyrotransport is a good (although expensive) alternative to the traditional travel-size optical mouse, and while primarily intended for controlling things such as PowerPoint presentations, is also useful for home theater PCs and multimedia laptops.
Measuring 1.25 inches wide, 2.5 inches long, and about 1 inch deep, the Gyrotransport is held in the hand with the forefinger resting underneath and the thumb on top. When activated, the mouse pointer effortlessly follows your hand movements across the screen. Unlike the Nintendo Wii control, for example, the gyroscope is only concerned with the device's orientation, not its relative location to a screen or receiver. Additionally, the RF receiver, housed in a USB key, requires no direct line of sight and claims a 100-foot range. The USB key also includes 1GB of storage--useful for bringing a multimedia presentation into a meeting, loading it up via the USB key, and controlling the show from a distance with the Gyrotransport.
Installation didn't require any special drivers, just standard Windows device installation. Because Windows recognizes the Gyrotransport as a mouse, an RF receiver, and a USB storage device, several runs through the new hardware wizard are required.
