System And Method For Automatically Producing Haptic Events From A Digital Audio File

Abstract

In an embodiment, a system and method for automatically converting a plurality of events in a plurality of channels in a structured representation sequence into haptic events. The method comprises calculating an event score for each event of the sequence in one or more channels. The method also comprises calculating a cumulative score based on the event scores in the one or more channels. The method includes selectively designating haptic events to the events based on the event scores in one or more selected channels, wherein the haptic events are output by a haptic actuator. This may be done by the system by calculating properties of the sound or by taking already existing values associated with those properties to efficiently produce haptic events.
