n. 1. Notional 'information-space' loaded with visual cues and navigable with brain-computer interfaces called 'cyberspace decks'; a characteristic prop of cyberpunk SF. At the time of this writing (mid-1991), serious efforts to construct virtual reality interfaces modeled explicitly on Gibsonian cyberspace are already under way, using more conventional devices such as glove sensors and binocular TV headsets.
