Gyration GO PRO 2.4GHz GYROTRANSPORT Air Mouse Presenter
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
<http://www.cnet.com/nintendo-wii.html> 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.

Controlling the cursor is accomplished by moving your wrist. The required
motion is subtle, but it can be adjusted, just like with any other mouse,
from the Windows control panel, to allow for increased or decreased
sensitivity in mouse movement. By default, the mouse cursor won't move
unless your thumb is holding down an activation button on the top of the
mouse. Press the thumb button, move the cursor where you want it, then
release the button to keep the cursor in place while you click the left or
right mouse buttons, which are also thumb controlled and located on the top
of the Gyrotransport. It may sound complicated, but as a long-time
gyroscopic mouse user, it's actually very intuitive after a day or two of
practice. Freeform control is also available by double-clicking the thumb
button.

For casual computing, or controlling multimedia software, the Gyrotransport
works as well as a traditional optical mouse and is especially suited for
couch-based Media Center controls, as it requires no mousing surface. For
applications requiring extrafine control, such as gaming and Photoshop
editing, it's less successful. Controlling the mouse pointer can be awkward
at first and requires a day or two of practice to feel natural. It's an
acquired taste to be sure, but fans of gyroscopic input devices swear by
them.

The USB-key RF receiver comes preloaded with Gyration's GyroTools software,
which lets you assign macros (called Swipes) to various mouse movements,
activated by pressing a second, smaller button on the top of the mouse. For
example, you can program the Gyrotransport to raise or lower the audio
volume when you press the thumb button and move the mouse up and down or to
move forward or backward in a document with a flick of the wrist.
