A new peripheral from Logitech subsidiary 3D Connexion gives users an additional tool for navigating 3D spaces. The device, called the SpaceNavigator, plugs into a USB port. Using six optical sensors, the 3D navigator is not a replacement for a mouse, but intended for use in the mouse-free hand.
The device was developed in conjunction with Google so that it can work natively with Google Earth. 3D Connexion will be offering a personal version with online support--the SpaceNavigator PE--for $49, and a professional version with online, e-mail and phone support for $99US.

More Infomation
The SpaceNavigator, which resembles an air hockey mallet, offers an alternative to the mouse movement and keystroke combinations currently used to navigate 3D environments or move 3D objects.
The device was developed in conjunction with Google so that it could work natively in Google Earth and Google SketchUp, a 3D modeling program. It can, however, be used with other 3D modeling programs like AutoCAD, according to Logitech.
Using six optical sensors, the 3D navigator is not a replacement for a mouse, but intended for use in the mouse-free hand. (If you use the mouse with your right hand, you would simultaneously use the SpaceNavigator with your left.)
Users 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 from its base, according to the San Jose, Calif.-based company. The device can also be used to manipulate 3D objects--enabling zooming, panning and rotating.
