Abstract
A haptic feedback device including a dual coil linear solenoid is provided. The dual coil linear solenoid construction provides a sense of a pulling force in an opposite direction from a pushing force sensed in the player's hand. A dynamic current source for each coil is disposed to generate dynamic magnetic flux in each coil, whereby a dynamic bi-directional force is exerted on the plunger. A plunger position controller controls the position of the plunger, whereby the plunger position controller applies a dynamic bi-directional force on the plunger to move the plunger to a target position based on the current position of the plunger detected by a plunger position sensor. The haptic feedback device is incorporated into a game controller. Video or arcade games incorporating the feedback device are also disclosed.
