PROJECT TITLE :

Designing Haptic Assistive Technology for Individuals Who Are Blind or Visually Impaired

ABSTRACT:

This paper considers problems relevant for the look and use of haptic technology for assistive devices for individuals who are blind or visually impaired in a number of the most important areas of importance: Braille reading, tactile graphics, orientation and mobility. We have a tendency to show that there is a wealth of behavioral research that is highly applicable to assistive technology design. During a few cases, conclusions from behavioral experiments are directly applied to style with positive results. Variations in brain organization and performance capabilities between people who are “early blind” and “late blind” from using the identical tactile/haptic accommodations, like the use of Braille, suggest the importance of training and assessing these groups individually. Sensible restrictions on device design, like performance limitations of the technology and value, raise queries on that aspects of those restrictions are actually important to overcome to achieve high performance. In general, this raises the question of what it means to supply practical equivalence as opposed to sensory equivalence.
