A multiuser, multi-interface computing system includes a computer system, and a continuous substrate including a first surface and a second surface. The substrate includes at least two touch sensitive regions, each touch sensitive region including a continuous touch sensitive surface that covers at least a portion of at least one display and an individual interface for selecting applications. The touch sensitive surface is configured to serve as the primary input to the computer system. The continuous substrate is transparent within the touch sensitive regions. The multiuser, multi-interface computing system is configured so that the at least two users can use the touch sensitive regions simultaneously.
