Abstract
An electronic gaming machine (EGM) includes a programmable haptic interface that produces, responsive to a force feedback signal, a variable amount of resistance to movement of a moveable element of the programmable haptic interface by a player as a haptic force feedback. A memory is coupled to a processor circuit and includes machine-readable instructions that cause the processor circuit to initiate a wagering game on the EGM. The processor circuit further generates the force feedback signal controlling an amount of resistance to movement of the moveable element of the programmable haptic interface based on a game event in the sequence of game events. The programmable haptic interface includes a magnetorheological fluid coupling the moveable element to a fixed housing that is mounted to the EGM and a circuit controlling a magnitude of a magnetic field that is applied across the magnetorheological fluid responsive to the force feedback signal.
