Labtec Spaceball 3D

Labtec Spaceball 3D ... naturally and intuitively with up to six degrees of freedom control (x, y, z translations and x, y, z with 10-bit precision) to simultaneously pan, zoom, and rotate 3D objects in every direction. The Spaceball lets you control the direction and speed of movement (velocity) by applying pushes, pulls, and twists to the ball. It operates two to three times faster than a mouse for 3D control.

The SpaceBall 3D Input Device increases productivity and improves 3D interactivity. Features include: removable palm that can be switched to optimize right and left hand use, lighted program function keys, improved movable ball control and improved ergonomic design.
