Abstract

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.
