Visually impaired individuals cannot lead their lives as comfortable as others. Therefore, new applications are being developed every passing day in order to make their lives easier. In this study, an electronic and computer-aided audio device was developed with the aim of making the learning of the periodic table easier for the visually impaired. In this device, a board includes buttons for ea...

BACKGROUND/AIMS Out of an estimated 90,000 visually impaired people in Scotland, 509 make use of a guide dog. Initial research in Northern Ireland suggests that the ophthalmic profile of guide dog owners (GDOs) is highly specific. The aim of this study was to compare the ophthalmic and visual characteristics of Scottish GDOs with other groups of visually impaired people. METHODS A random samp...

According to the National Center for Health Statistics approximately 1.3 million people in the United States are legally visually impaired. Two of the primary challenges that visually impaired people face every day are mobility and orientation. Less than 10% of visually impaired people use canes and approximately 5% use guide dogs. The project scope is to develop a working prototype using ultra...

Visually impaired people have difficulties in perceiving environmental information including the size of a space and the presence of objects, by means of visual information. Particularly, auditory-trained visually impaired people can recognize 3-D spatial information by means of environmental sounds. However, a systematic learning method of auditory spatial perception for walking training has n...

The aim of this study was to investigate the possible beneficial effects of regular physical activity on auditory reaction time and the duration of hearing in congenital visually impaired adolescents by examining some auditory performances involving perception and motor components. Forty visually impaired and 30 sighted-control adolescents, 10 to 22 years old (14.04 ± 2.77) participated in the ...

Research into haptic picture perception has mostly concerned adult participants, and little is known about haptic picture perception in visually impaired and sighted children. In the present study, we compared 13 visually impaired children (early blind and low vision) aged 9-10 years and 13 agematched blindfolded sighted children on their ability to identify raised-line pictures of common objec...
