(57) ABSTRACT
A video surface is constructed by adjoining a large number ol flat screen display devices together. Each screen on this surface is controlled by its own computer processor and these processors are networked together. Superimposed over this surface is a tiling ol transparent touch-sensitive screens which allow for user input. The resulting display is thin, has a very high resolution, appears to be a single large screen to the user, and is capable ol supporting many different types ol human-machine interaction.
