Dataglove <1987>

The earliest device for interactivity in a virtual environment and with virtual objects was the dataglove developed at NASA Ames. Based on an invention developed by Tom Zimmerman while he was at Atari Research for measuring motion of a single finger, the gloves were custom built for NASA by Zimmerman at VPL Research and later marketed by VPL as a commercial product.

These gloves were fitted with special sensors to measure the bend of the fingers and equipped with a magnetic tracking system that allowed for the glove, and the hand inside it, to be followed in 3D space and the ability to handle virtual objects freely. Special software was also developed in the VIEW lab to allow different gestures for specific actions and system commands such as "flying" through the virtual environment, interacting with virtual menus, or easily scaling models of virtual objects.
