Systems, methods, and computer program products for providing composite haptic effects are disclosed. One disclosed method includes detecting a touch occurring in a touch area when an object contacts a touch surface and selecting a composite haptic effect to generate in response to the touch, the composite haptic effect including at least one surface-based haptic effect and at least one other effect. Based on the selected composite haptic effect, a first haptic signal can be sent to cause an actuator to vary a coefficient of friction of the touch surface and a second actuator can be caused to provide a second haptic output in addition to the variation in the coefficient of friction. The second haptic signal can be sent to a second actuator or the same actuator (s) used to vary the coefficient of friction and can be used to generate the second haptic output.

Systems and methods for friction displays and additional haptic effects

A touch-enabled device can simulate one or more features in a touch area. Features may include, but are not limited to, changes in texture and/or simulation of boundaries, obstacles, or other discontinuities in the touch surface that can be perceived through use of an object in contact with the surface. Systems include a sensor configured to detect a touch in a touch area when an object contacts a touch surface, an actuator, and one or more processors. The processor can determine a position of the touch using the sensor and select a haptic effect to generate based at least in part on the position, the haptic effect selected to simulate the presence of a feature at or near the determined position. The processor can transmit a haptic signal to generate the identified haptic effect using the actuator. Some features are simulated by varying the coefficient of friction of the touch surface.
