Sound vest
Vibratory motors are used to generate a haptic language for music or other sound that is integrated into wearable technology. The disclosed system enables the creation of a family of devices that allow people with hearing impairments to experience sounds such as music or other auditory input to the system. For example, a “sound vest” transforms musical input to haptic signals so that users can experience their favorite music in a unique way, and can also recognize auditory cues in the user's everyday environment and convey this information to the user using haptic signals.
1. A system for transforming audio information to a haptic language, comprising:
a signal processor ( 20 ) configured to receive an audio input ( 10 ) and simultaneously generate a plurality of electrical driving signals ( 30 ) according to a predefined mapping from audio signals comprising portions of said audio input to each of said plurality of electrical driving signals;
a wearable vest ( 40 ); and
a network of a plurality of vibratory motors (M 1 -M 4 ) incorporated into the wearable vest, wherein the plurality of electrical driving signals generated by the signal processor are used to drive the plurality of vibratory motors according to a predefined mapping of audio signals comprising portions of said audio input to a plurality of different regions of the vest.
2. A method for transforming audio information to a haptic language expressed through a wearable vest, comprising:
using a signal processor to receive an audio input and simultaneously generate a plurality of electrical driving signals according to a predefined mapping from audio signals comprising portions of said audio input to each of said plurality of electrical driving signals; and
using the plurality of electrical driving signals to drive a network of a plurality of vibratory motors incorporated into the wearable vest, wherein the plurality of electrical driving signals are used to drive the plurality of vibratory motors according to a predefined mapping of audio signals comprising portions of said audio input to a plurality of different regions of the vest.
3. The method of claim 2 , further comprising transforming the audio data into the plurality of electrical driving signals by obtaining audio data in a prescribed format; organizing the audio data into 4 tracks representing vocals, drums, guitars, and bass; mapping each of the four tracks to one of the plurality of different regions of the vest; and using each of the respective tracks of data to drive the motors in the corresponding region.
4. The method of claim 3 , wherein the prescribed format is a MIDI (Musical Instrument Digital Interface) format.
