Abstract
Triggering haptic sensations based on sound output from a computer device. A portion of sound data is stored that is output to a user as audio from an application program running on a computer. The portion of sound data is analyzed using intelligent heuristics to extract at least one sound feature from the sound data. The execution of at least one haptic effect is triggered based on the sound feature, where the haptic effect is commanded to the haptic feedback device approximately correlated to the output of the portion of sound to the user as audio. The haptic effect causes a haptic sensation to be output to the user. Different haptic effects can be associated with different sound features, frequency ranges, amplitudes, etc.

29. A method for triggering a haptic effect, comprising:
-
receiving, by at least one processor, sound data; applying, by the processor, a plurality of filters to the sound data, wherein the plurality of filters divide the sound data into a plurality of frequency ranges, and wherein the plurality of filters includes at least one bandpass filter; analyzing, by the processor, at least one frequency range; determining, by the processor, one or more sound features based on the analyzed at least one frequency range; and triggering, by the processor, at least one haptic effect based on the determined one or more sound features.
