Images: A mouse counterpart for the 3D world

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 $99.
