TLDR
Two main problems to be solved in designing truly effective mobility aids for the blind are to determine what kinds and how many pieces of information are necessary and/or sufficient to mobilize humans, and to establish the optimal coding and display method of the acquired information.Abstract:

An experimental system for auditory image representations
TL;DR: Computerized sampling of the system output and subsequent calculation of the approximate inverse (sound-to-image) mapping provided the first convincing experimental evidence for the preservation of visual information in sound representations of complicated images.

Differentiating sonar reflections from corners and planes by employing an intelligent sensor
Billur Barshan,Roman Kuc +1 more
TL;DR: A system using two Polaroid transducers is described that correctly discriminates between corners and planes for inclination angles within +or-10 degrees of the transducer orientation, allowing the system to operate over an extended range.
Journal ArticleDOI
A literature review: robots in medicine
TL;DR: A variety of robots that assist or perform surgery is surveyed, including positioning in stereotactic neurosurgery, patient manipulation, an in vivo spinal kinematic instrument, and robotic radial keratotomy, among others.

The NavBelt-a computerized travel aid for the blind based on mobile robotics technology
TL;DR: Experimental results with the NavBelt simulator and a portable prototype show that users can travel safely in an unfamiliar and cluttered environment at speeds of up to 0.8 m/s.
Journal ArticleDOI
A brief taxonomy of tactile illusions and demonstrations that can be done in a hardware store.
TL;DR: This paper surveys more than twenty types of tactile illusions and discusses several of their aspects, including the ease with which they can be demonstrated and whether they have clear visual analogs.

Vision substitution by tactile image projection.
TL;DR: In this paper, a vision substitution system for the blind is described, which is used to study the processing of afferent information in the central nervous system, and the results obtained with preliminary models have been briefly reported.

TL;DR: Physiological and psychophysical functions underlying electrocutaneous stimulation are discussed, including a comparative review of stimulus parameters and coding formats.
Journal ArticleDOI
Tactile Television - Mechanical and Electrical Image Projection
TL;DR: In this article, the feasibility of communicating pictorial information through the skin has been demonstrated, and a tactile television system has been used to allow blind subjects to determine the position, size, shape, and orientation of visible objects and to track moving targets.
Journal ArticleDOI
Electrocutaneous stimulation: Psychometric functions and temporal integration
TL;DR: In this paper, psychometric functions and psychophysical strength-duration curves were obtained with rectangular electro-cutaneous pulses, with the standard deviation of the distribution only about 0.08 times the threshold.
