Vision Substitution by Tactile Image Projection

  title={Vision Substitution by Tactile Image Projection},
  author={Paul Bach-y-Rita and Carter Collins and Frank A. Saunders and B White and Lawrence A. Scadden},
WE describe here a vision substitution system which is being developed as a practical aid for the blind and as a means of studying the processing of afferent information in the central nervous system. The theoretical neurophysiological basis1 and the physical concept of the instrumentation2 have been discussed previously, and results obtained with preliminary models have been briefly reported3. A detailed description of the apparatus will appear elsewhere (manuscript in preparation). 

Topics from this paper

Neurophysiological Basis of a Tactile Vision-Substitution System
The instrumentation produced and the results obtained with the tactile vision-substitution system (TVSS) developed in our laboratories have been described by Collins [1] and White [2]. With the TVSS,Expand

The theoretical basis for sensory substitution is examined primarily in regard to the capacity of the somatosensory system to mediate high resolution "visual" information. Expand
Visual Substitution Systems: Control and Information Processing Considerations
A detailed discussion of the visual mechanisms found in the higher vertebrates is used as the basis for exploring the problems found in creating visual substitution systems. Specific attention isExpand
We have built and operated a tactile vision substitution system based on 48 piezoelectric actuators assembled in a movable tactile output unit. The unit can be positioned at any location on a twoExpand
Seeing with the skin
After surprisingly little training, Ss are able to recognize common objects and to describe their arrangement in three-dimensional space and achieve external subjective localization of the percepts when given control of the sensing and imaging device, a television camera. Expand
Plastic Brain Mechanisms in Sensory Substitution
Development of a tactile vision substitution system (TVSS) to present pictorial information to the blind, in which optical images picked up through a television camera are presented as a two-dimensional pattern of pulses to a mosaic of stimulators arranged on the skin of the trunk. Expand
Tactile Vision Substitution: Some Instrumentation and Perceptual Considerations
The development of various sensory substitution devices and aids for the blind has been based on the notion that the human perceptual systems are remarkably flexible in their functional capacitiesExpand

This paper surveys more than twenty types of tactile illusions and discusses several of their aspects. These aspects include the ease with which they can be demonstrated and whether they have clearExpand
Tactile Substitution for Vision
Sensory Substitution is an approach that allows perceiving environmental information that is normally received via one sense through another sense via another sense through the use of receptors of the substituting modality. Expand
Design of Sensory Substitution Systems for the Blind
Many efforts have been devoted to the design of sensory aids for blind persons. Since the introduction of Braille last century, a classical way has been to use the remaining sensory systems (mainlyExpand


The aim of this paper is to examine the evidence for plasticity as a fundamental basis for the development of a high resolution vision substitution system. Expand
