VisionKey brings the latest in eye-controlled communication technology to enable users to utilize eye movements for complete computer access and for augmentative communication. It is lightweight and fully portable. VisionKey comes with a stand-alone, separate control unit with a display and a voice synthesizer; for person-to-person communication no computer is needed. A standard USB keyboard interface is provided for computer control and the unit can also be powered this way.
