Abstract: The present invention preferably includes a system and method for allowing a plurality of input stations such as touchscreen input devices, for example, to simultaneously provide input to a central processing unit executing a computerized simulation program such as a game simulation program. The invention allows a plurality of input groups, for example, to be received by the central processing unit. Each received input group preferably causes a graphical effect on a parameter or function provided by the simulation program. Each graphical effect is preferably displayed on a corresponding computer monitor, for example, thereby allowing a first participant to view a first graphical effect and a second participant to view a second graphical effect. The system can allow participants exercising control over the touchscreen input devices to experience a more real “feel” of the game, that is, a feeling as though the participant were participating in the real-life scenario emulated by the simulation program.
