KINESTHETIC HAPTIC FEEDBACK FOR HAPTICALLY-ENABLED SURFACES

摘要

A haptic system and a method of manufacturing a haptic system are provided. The haptic system includes a substrate and a haptic actuator. The substrate includes a region having a residual stress. The haptic actuator is associated with the substrate on or near the region and is configured to generate a haptic effect in response to receiving a haptic effect signal. The haptic effect generated by the haptic actuator is amplified by the residual stress associated with the region. The method of manufacturing the haptic system includes deforming an substrate into a deformed shape, applying an epoxy to the substrate, affixing a haptic actuator to the epoxy and curing the epoxy while holding the substrate in the deformed shape, and, after curing, releasing the substrate to create the region having the residual stress.
