Abstract

One illustrative system disclosed herein includes a deformation sensor configured to detect a deformation of a deformable surface and transmit a first sensor signal associated with the deformation. The system also includes a sensor configured to detect a user interaction with a user input device and transmit a second sensor signal associated with the user interaction. The system further includes a processor configured to: receive the first sensor signal; receive the second sensor signal; execute a function based at least in part on the first sensor signal and the second sensor signal. The processor is also configured to: determine a haptic effect based at least in part on the first sensor signal or the second sensor signal; and transmit a haptic signal associated with the haptic effect to a haptic output device configured to receive the haptic signal and output the haptic effect.
