Interactive simulation including force feedback
First Claim
1. An interactive simulation system adapted to be used with a computer programmed with simulation rules, comprising:
- a control unit adapted to connect to the computer and to provide information and control signals to the computer to interact with the simulation rules and to receive information and control signals from the computer, said simulation rules being used for controlling feedback and modeling interaction of an operator with elements graphically displayed in a simulation or a game;
a joystick adapted to be moved with at least two degrees-of-freedom by an operator and by actuators interconnecting the joystick to the control unit, said joystick including a switch that is selectively actuated by the operator to control a state of a switch signal that is conveyed to the computer by the control unit; and
programmable means for processing signals from the computer to generate signals that drive the actuators to move the joystick and to apply force and touch feedback in the at least two degrees-of-freedom to the joystick and to the operator, the applied forces based on internal programming within the programmable means, the state of the switch being controlled by the operator, events occurring in the simulation or in the game, and movements of and forces applied to the joystick by the operator that enable the operator to feel the elements graphically displayed by applying a force to the operator through the joystick, said force corresponding to a state of at least one of the elements that are graphically displayed, whereby there is continuous interaction among motion of the joystick, the state of the switch controlled by the operator, the events and the elements graphically displayed in the simulation or in the game, and forces applied to and applied by the joystick.

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 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.
