Abstract: Two experiments were conducted to determine consumers’ ability to use a BrailleNote GPS (global positioning system). In Experiment 1, after being disoriented, 3 participants with varying degrees of visual impairment located a target house in a residential neighborhood, with the GPS and without it. Mean orientation time with the BrailleNote was 45 seconds compared to 6 minutes without it, and target efficiency increased fourfold. Experiment 2 had one participant locating 5 target houses within a familiar residential neighborhood with the BrailleNote and without it. The resulting higher efficiency in locating the targets with the GPS than without it demonstrated the advantage of GPS technology even in familiar areas. Implications of the findings for consumers and the instructional community are discussed.
