Crackle: A Dynamic Mobile Multitouch Topology for Exploratory Sound Interaction

This paper describes the design of Crackle, a interactivesound and touch experience inspired by the CrackleBox.We begin by describing a ruleset for Crackle's interactionderived from the salient interactive qualities of the CrackleBox. An implementation strategy is then described forrealizing the ruleset as an application for the iPhone. Thepaper goes on to consider the potential of using Crackleas an encapsulated interaction paradigm for exploring arbitrary sound spaces, and concludes with lessons learned ondesigning for multitouch surfaces as expressive input sensors.
