Method and apparatus for sensory substitution
An apparatus and method for use in treating tinnitus, employs a sound processing unit, a tactile unit, and an interface therebetween. The tactile unit comprises an array of stimulators each of which can be independently actuated to apply a tactile stimulus to a subject, and an input for receiving a plurality of actuation signals from the interface and directing individual actuation signals to individual stimulators. The sound processing unit receives an audio signal at an input, analyses the signal with a digital signal processor to generate the actuation signals which are representative of the audio signal, and provides the plurality of actuation signals to the interface. In a preferred embodiment the digital signal processor divides the audio signal into a series of frames in the time domain, performs a transform on each frame to generate a set of coefficients representing said frame, and maps the set of coefficients to a set of actuation signals to be applied to the array.

General purpose device to assist the hard of hearing
An approach to notifying a person who is hard of hearing of audible events based on a configurable device. The device has microphones and associated buttons mounted on its surface. The user programs the device by depressing a selected button longer than a preconfigured time to place the device in listen mode. The user generates the desired audible event and the device records the audible event. The selected button is depressed again to instruct the device to associate the audible event with a visual alarm indicator of colored/flashing lights and/or a text projection. The device listens for the audible event and activates the visual alarm indicator when the device detects the audible event.

Providing information to a user through somatosensory feedback
A hearing device may provide hearing-to-touch sensory substitution as a therapeutic approach to deafness. Through use of signal processing on received signals, the hearing device may provide better accuracy with the hearing-to-touch sensory substitution by extending beyond the simple filtering of an incoming audio stream as found in previous tactile hearing aids. The signal processing may include low bitrate audio compression algorithms, such as linear predictive coding, mathematical transforms, such as Fourier transforms, and/or wavelet algorithms. The processed signals may activate tactile interface devices that provide touch sensation to a user. For example, the tactile interface devices may be vibrating devices attached to a vest, which is worn by the user. The vest may also provide other types of information to the user.

Tactile pattern music generator and player
A device that produces patterned tactile sensations or events discernible to human touch from micro-actuators housed in a fabric, or other pliable material, where such actuated sensations or events are discernible by a user donning the fabric. The device is configured to convert electronically stored music or audio data into a sequence of patterned tactile sensations or events in a matrix across the fabric, providing a tactile representation of the music or audio data to the user. The discernible tactile sensations or events may alternately comprise retractable physical features, electric stimuli, and/or combinations of these.
