Abstract
A touch interface device includes a touch surface, an actuator, and an electrode. The actuator is coupled with the touch surface and is configured to move the touch surface in one or more directions. The electrode is coupled with the touch surface and is configured to impart a normal electrostatic force on one or more appendages of a human operator that engage the touch surface when an electric current is conveyed to the electrode. Movement of the touch surface by the actuator and the electrostatic force provided by the electrode are synchronized to control one or more of a magnitude or a direction of a shear force applied to the one or more appendages that engage the touch surface.
