Baruch College Computer Center for Visually Impaired People
Project Overview: The Talking Tactile Tablet (TTT)is an
inexpensive computer peripheral device that runs interactive audio-tactile
applications used by visually impaired individuals. Users place
raised-line and textured-drawing sheets on TTT, then press parts of the
tactile image to elicit appropriate audio responses. Software developed for
TTT includes reference materials, games, and an authoring tool. The system
permits individuals to learn and have fun with multimedia
programs. TTT extends educational and entertainment possibilities for use
by a previously under-served group.
Problem Addressed: People with visual impairments struggle to maintain parity with sighted
peers in educational and employment contexts because of an inability to
perceive pictorial information. This leads to insurmountable
challenges in mastering graphical concepts associated with math, geography,
science and other disciplines. The burgeoning multi-media world of
interactive materials is largely closed to visually impaired people, because
they cannot readily manipulate a mouse. Thus this group of talented
individuals is routinely prevented from contributing. Economical and
effective solutions to the graphical impasse need to be created.
Technology Solution: The Tablet acts as a "viewer" for audio/tactile drawings held in place on a touch screen attached to a controller card housed in a hinged frame. TTT connects to any Windows or Macintosh computer with only a USB cable. Users place a tactile drawing on the device, plug the unit into a PC, place a disk with application software into the CD drive and begin. By comparing the position of users' finger pressures against a database of predefined hotspots, the computer provides identifying audio feedback as confirmation and elaboration of information supplied tactually.
