Abstract
Abstract Interactive simulation including force feedback. The system includes a computer game display unit programmed with simulation rules. A control unit is connected to the computer and provides information and control signals to the computer to interact with the stored simulation rules and to receive information and control signals from the computer. A movable structure for movement in at least two degrees-of-freedom by an operator is interconnected to the control unit by means of actuators. A programmable unit processes signals and information from the computer to generate signals to drive the actuators so as to apply forces in the at least two degrees-of-freedom to the movable structure and thereby to the operator. The applied forces are based on internal programming within the programmable unit, events occurring in the simulation and movements of and forces applied to the movable structure by the operator. The system of the invention thereby provides continuous interaction among motion of and forces applied by the movable structure, the events in the simulation and forces applied to and applied by the movable structure.
