Abstract
A haptic peripheral including a magnetic actuator coupled to a user input element for providing haptic effects to the user input element. The magnetic actuator includes at least two opposing programmable magnets, a first programmable magnet and a second programmable magnet, with pre-programmed patterns to control the motion of the user input element. Each programmable magnet has a pre-programmed pattern of magnetic elements. The pre-programmed patterns of the magnetic elements interact with each other to cause haptic effects. In order to vary to haptic effects output by the magnetic actuator, the second programmable magnet is spun, rotated, or otherwise moved to change the orientation or position of the pre-programmed pattern. The re-oriented pattern of the second programmable magnet changes the interaction between the first and second programmable magnets and thereby results in different haptic effects being output to the user input device.
