A touch screen system for people with disabilities provides an access screen presenting multiple paths of communication and multiple methods of input for a variety of disabilities. People with disabilities communicating with this access screen configure the touch screen for their particular communication needs, allowing use of the touch screen efficiently both for individuals with disabilities and for individuals without disabilities. Individuals with occasional difficulty in interpreting written legends on particular virtual buttons may use a distinct access button to provide an augmented legend for those buttons on an "as needed" basis.

[ I claim:] [1.] A touch screen for those with reduced ability to interpret visual expressions comprising:an electronic display screen having a smooth display area without spatially distinguishing tactile landmarks;a touch panel commensurate with the display area and providing a coordinate output indicating only a presence or absence of touch points in the display area;an access button positioned at a predetermined fixed location to be actuated by the user to enable an access mode;audio circuitry for generating speech in response to electrical commands from an electronic processor;an electronic processor communicating with the electronic display screen, the touch panel, and the access button and executing a stored program to:(a) display on the electronic display screen a set of virtual buttons, the buttons having graphical boundaries and a graphical legend and locations different from the location of the access button;(b) when the access mode is not enabled and when a touch point is detected within a boundary of a virtual button, the electronic processor executing a program action associated with the virtual button; and(c) when the access mode is enabled and when a touch point is detected within the boundary of the virtual button, the electronic processor outputting via the audio circuitry a spoken representation of the information of the graphical legend of the virtual button easier for the user to interpret.
