Introduction: Accessibility of Voice over Internet Protocol (VoIP) systems was tested with a hands-on usability study and an online survey of VoIP users who are visually impaired. The survey examined the importance of common VoIP features, and both methods assessed difficulty in using those features. Methods: The usability test included four paid…

USING A SAMPLE OF 94 CHILDREN (31 TO 54 MONTHS OLD), THIS STUDY COMPARED EIGHT VISION SCREENING PROCEDURES FOR YOUNG CHILDREN IN THE ABILITY TO TEST FOR SEVERAL VISUAL FUNCTIONS, AND PREFERENCE AMONG THEM BY CHILDREN. THE SUBJECTS WERE ORIGINALLY TESTED USING THE EIGHT SCREENING TESTS, AND 6 MONTHS LATER 40 OF THE CHILDREN WERE RETESTED FOR…

Early detection of significant vision problems in children is a high priority for pediatricians and school nurses. Routine vision screening is a necessary part of that detection and has traditionally involved acuity charts. However, photoscreening in which "red eye" is elicited to show whether each eye is focusing may outperform routine acuity…

Intended for the specialist in low vision rehabilitation, the manual provides information on low vision evaluation, low vision aids, and perceptual learning. A large section of the document is devoted to illustrations and information on (including use, cost, and source) 15 near and 8 distance vision aids such as the Coil Hi-Power Reader, hand…

Fifty adults (ages 28-86) with macular degeneration were given the Low Vision Reading Comprehension Assessment (LVRCA) to test its reliability and validity in evaluating the reading comprehension of those with vision impairments. The LVRCA was found to take only nine minutes to administer and was a valid and reliable tool. (CR)

Although several vision screening techniques are available for infants, none is routinely used. Visual deficits are often first detected through required preschool vision screenings, which vary in their comprehensiveness. No standardization for testing or administration exists. Some of the testing procedures used may have inappropriately high…

The assessment of behavior patterns and levels of functioning of visually handicapped students is essential for establishing effective educational programs. The article discusses the factors in formative assessment, the types of data to be collected, and the most appropriate measurement instruments that are available to evaluate a variety of…

In the analysis of ability structure and loss of vision, 228 blind persons (153 male, 75 female) heterogenous in respect to chronological age, sex, degree of blindness, age at onset, and duration, were compared to sighted controls. A test battery was administered which included tests for verbal comprehension, mental arithmetic, spatial ability,…
