ABSTRACT:
A computer-based system permitting a visually impaired user to interact with tactile graphic-based interactive software applications is provided. The system includes a host computer having a data processor and a drive for running the interactive software applications and a pressure sensitive work pad. The work pad has X and Y pressure sensitive members disposed in a grid array for providing unique location output signals corresponding to each different location on the grid array. The work pad is operatively connected to the host computer and an overlay comprising a sheet is placed over an upper surface of the work pad. The overlay having a work space which bears tactile indicia which corresponds to a selected one of the interactive software applications and also includes a tactile graphical user interface (TGUI) formed thereon. The TGUI has a plurality of tactile control members which generate location output signals when pressed. These output signals are communicated to the computer which processes the signals as control signals directing the computer to perform an operation. Methods of calibrating the overlays and identifying the overlays are also provided.
