Abstract
A system for generating a haptic effect with an electrostatic device, alone or in combination with actuators or other devices configured to generate a haptic effect. The system may generate the haptic effect to simulate a coefficient of friction or texture on the surface of a user interface, such as a display screen or touchpad. The simulated coefficient of friction may be adjusted to convey other properties on the user interface surface. The system may also include sensors that measure the simulated coefficient of friction and the impedance at the surface.
