Navigator could be 3D life-saver
Alternative device is meant for your mouse-free hand
It may look like an air hockey mallet, but don't laugh--it could be your survival guide if you get lost in Second Life.
The "SpaceNavigator," developed by Logitech subsidiary 3D Connexion, offers an alternative to the mouse movement and keystroke combinations now used to navigate 3D environments or move 3D objects.
Using six optical sensors, the navigator isn't a replacement for a mouse but is intended for use in the mouse-free hand. You can move through a 3D space by gripping the top of the SpaceNavigator and sliding it around, twisting it like a dial, tilting it, pressing down on the center of the mallet or slightly lifting it.
Just be careful not to get carried away with it, as some gamers have done with the Wii.
