The long-range purpose of this research is to enable the design of better vibrotactile communication aids for the profoundly deaf. the immediate goal is to assess the potential of piezoelectric bimorphs as a means of implementing more appropriate vibrotactile transducers than are available.… More

The long-range goal of this project is to enable the implementation of a tactile fm trainer consisting of an fm receiver, a five-channel tactile aid, and a high-gain bilateral hearing aid as an integral unit for use by severely and profoundly deaf children. the immediate goals are to assess the… More

The long-term objective of this study is to make available wearable tactile aids with eight or more channels and with suitable performance, size, and convenience characteristics to meet the requirements of the market. the immediate task is to assess the potential of a specific type of vibrator… More

The long-term purpose of this work is to develop an improvedmethod of displaying tactile information for profoundly deafindividuals. the issue addressed is whether the tactile sensory system can benefit from encoding schemes that present data in a manner more analogous to the way the basilar… More

The purpose of this work is to develop improved methods for increasing the saliency of acoustic signals for listeners with limited hearing and poor frequency selectivity. the long term goal is to develop wearable auditory devices so this population has a third alternative for hearing assistance in… More

It is clear that the utility of tactile aids degrades even more rapidly in the presence of noise than is the case for hearing aids. This is particularly apparent in the integration of visual and tactile cues as for example in speechreading. One reason may be is because many of the cues derived from… More

Tactiling is the name given to a method of tactually supplementing speechreading. According to this method a deaf speechreader places his hand on a talker's shoulder with his fingers lightly against the neck; thus, the talker will obtain clues relating to voicing and dynamic speech intensity. The… More

DESCRIPTION (provided by applicant): Bluetooth is a new short-range wireless communication technology. Among the important strengths of this technology are resistance to interference from other wireless transmissions, low cost, low power, small size, and ability to form what are termed in… More
