Abstract: An interface device configured to provide an electrostatic friction (ESF) effect is disclosed. The interface device comprises a plurality of electrodes disposed at a surface of the interface device. It further comprises a signal generating circuit configured to generate a first drive signal at an output of the signal generating circuit, and comprises a plurality of frequency filter units or delay elements electrically connected to the signal generating circuit and to the plurality of electrodes. The interface device further comprises a control unit configured to use the plurality of frequency filter units or delay elements: (i) to cause only a subset of one or more electrodes of the plurality of electrodes to output one or more respective ESF effects with the first drive signal, or (ii) to cause at least two electrodes to output respective ESF effects with the first drive signal in different respective manners.

Abstract: A haptic effect enabled system generates a haptic effect using an electric potential responsive fluid. A haptic enabled apparatus includes a fluid and a substrate. The fluid is responsive to an electric field. The substrate is at least partially flexible and defines a channel. The fluid is positioned within at least a portion of the channel. A portion of the substrate proximal to the fluid is stiffer than a portion of the substrate spaced from the fluid, thereby creating a haptic effect.
