This article presents the results of two single-subject experiments that were designed to determine consumers’ ability to use a BrailleNote GPS. The participants decreased their mean orientation time from 6 minutes to 45 seconds and increased their target- location efficiency fourfold with BGPS than without BGPS. Additional results and implications for the field are presented.

This article presents a systematic review of the research evidence on the effects of the characteristics of typefaces on the legibility of text for adult readers with low vision. The review revealed that research has not produced consistent findings and thus that there is a need to develop standards and guidelines that are informed by evidence.

This article analyzes a corpus of 1,600 brailling errors made by one expert braillist. It presents a testable model of braille writing and shows that the subject braillist stores standard braille contractions as part of the orthographic representation of words, rather than imposing contractions on a serially ordered string of letters.
