Abstract

Accessible global positioning systems (GPS) are increasingly popular as an orientation aid for people with vision impairment. Adapted GPS such as the BrailleNote, Trekker, Trekker Breeze and Wayfinder Access are discussed. Limitations of adapted GPS devices for the older user are considered. Major benefits of the older user with vision impairment using GPS include independent mobility, increased confidence in wayfinding and decreased reliance on memory for navigation tasks.
