LOW-FREQUENCY EFFECTS HAPTIC CONVERSION SYSTEM

摘要

A system is provided that produces haptic effects. The system receives an audio signal that includes a low-frequency effects audio signal. The system further extracts the low-frequency effects audio signal from the audio signal. The system further converts the low-frequency effects audio signal into a haptic signal by shifting frequencies of the low-frequency effects audio signal to frequencies within a target frequency range of a haptic output device. The system further sends the haptic signal to the haptic output device, where the haptic signal causes the haptic output device to output one or more haptic effects.

主权项

1. A non-transitory computer-readable medium having instructions stored thereon that, when executed by a processor, cause the processor to produce a haptic signal, the producing comprising:
receiving a multichannel audio signal comprising a low-frequency effects audio signal; extracting the low-frequency effects audio signal from the multichannel audio signal; converting the low-frequency effects audio signal into the haptic signal; providing, by an authoring tool, a parameter of the haptic signal to a user for adjusting the parameter; receiving a user adjustment to the parameter; and embedding the haptic signal in a data stream that encodes at least the multichannel audio signal, wherein the haptic signal is encoded within the low-frequency effects audio signal.
