Abstract

A system for outputting virtual surface textures, related mobile and other devices, and related methods are disclosed. In one embodiment, the system includes a first haptic component that is configured to output a first virtual surface texture in response to being provided with an electrical signal. The system further includes a memory device that is capable of storing information, and a processing device coupled at least indirectly to the memory device and the haptic component. The processing device at least indirectly causes the electrical signal to be provided to the haptic component upon determining a first condition to have been satisfied, the electrical signal being based at least in part upon the stored information. Also, at least some of the stored information upon which the electrical signal is based is derived at least indirectly from an additional signal received from either the first haptic component or another haptic component.
