Haptic output devices

Abstract

Haptic output devices may provide haptic output to a user. The haptic output devices may include foot-shaped structures with cavities configured to receive the feet of users. The haptic output devices may also include foot platforms with planar exterior surfaces on which a user may stand. In hybrid arrangements, haptic output devices include foot-shaped support structures with components such as magnets and a foot platform components with corresponding electromagnets. Haptic output components such as piezoelectric components, electroactive polymer components, electromagnetic actuators, and other haptic output components may be mounted to haptic output device support structures in arrays. Shear forces and forces normal to the inner surfaces of a foot-shaped support surface and/or the exterior surface of a foot platform may be generated. Haptic output may be generated based on sensor signals such as sensor signals associated with foot movement.
