Abstract

One illustrative system disclosed herein includes a first haptic output device configured to receive a first haptic signal and output a first haptic effect to a deformable surface and a second haptic output device configured to receive a second haptic signal and output a second haptic effect to the deformable surface. The illustrative system further includes a processor coupled to the first haptic output device and the second haptic output device, the processor configured to: determine an event, determine a first haptic effect and a second haptic effect based at least in part on the event, transmit a first haptic signal associated with the first haptic effect to the first haptic output device, and transmit a second haptic signal associated with the second haptic effect to the second haptic output device.
