The system subsequently outputs the one or more haptic effects based on the generated haptic signal. The system can also shift a frequency of the input, and also filter the input, before the system applies the granular synthesis algorithm to the input.

Abstract: A gaming concept in which each user in a single-player or a multi-player game is enabled to create artwork or graffiti work virtually or on actual surfaces using haptic-enhanced controllers.
