Abstract, A computer terminal device includes a flat screen display element and a touch-sensitive element. Simulated keyboards can be displayed on the display element and, in response to the touching of the simulated keys generate, appropriate control signals. The same flat screen display can also be used to display computer output, either the result of calculations or the result of information retrieval requests. The slim silhouette of this terminal makes it ideal for hostile environments such as the factory floor or the hospital room.
