Haptic granular synthesis: targeting, visualisation and texturing
This work introduces the idea of haptic rendering using granular synthesis - an established technique for synthesising audio. It describes the technique along with potential application areas, and initial results from an implementation on a PHANToM force feedback device. Three main applications are considered. Firstly, rendering of probabilistic vector fields for presenting ambiguity and context information to the user. Secondly, the possibility of producing textured virtual objects using granular synthesis is discussed. Thirdly, we use the approach to display scatterplot data on haptic devices.
