The Total Access System (TAS) provides external access to all user functions on any computer or IT device. The TAS separates user interaction functions from the machine interface and allows the same operational procedures to be used with different target devices.
The Total Access System has three components:
An Accessor is a personalized device that provides its user with his or her preferred interaction modalities. Options range from specialized keyboards and pointing devices through to sophisticated speech recognizers, head trackers and eye gaze trackers.
Total Access Port (TAP)
A small keyboard and mouse emulator that provides direct access to any user accessible functions on the target computer.
A communication protocol that allows any accessor to connect to any TAP. The connection can be wired or wireless (Infrared or Radio)
Advantages of the TAS
The TAS has been sold commercially since 1995. Versions have been produced for IBM PC, Macintosh, Sun workstations, SGI workstations and HP workstations.
Research prototypes have been developed for smart house interfaces and video game consoles.
