Introduction
About the project
This project was initiated to examine the impact of GPS technology on the orientation and
mobility of secondary students with visual impairments in British Columbia. The goal of
the project is to explore the Trekker GPS system, currently available for students with
visual impairments, and assess its usefulness to support Orientation and Mobility
capabilities.
Project organizers and participants wish to thank Dave Rathwell, teacher of the visually
impaired, orientation and mobility instructor, and assistive technology consultant, for his
dedication and expertise in developing this set of Trekker lessons.
About Trekker
Trekker, a GPS system for the Blind and visually impaired, uses GPS and digital maps to
help blind persons find their way in urban and rural areas. Trekker users can pinpoint
where they are, learn about area attractions, and find out how to get to specific
destinations.
Fitting in the palm of the hand, this personal digital assistant (PDA) technology offers the
visually impaired user greater freedom, raising their confidence in their ability to travel.
Trekker helps guide the visually impaired through their environment. It complements
existing aids (white canes and guide dogs). It does not replace them. Sleek and discreet,
Trekker provides information in the most natural way possible and allows users to record
both vocal and written notes.
Important Caution
The Trekker system is designed as an ORIENTATION AID only, and must not, at any time, be used as
the only aid while traveling. A conventional mobility aid should be used in conjunction with the GPs
unit as TREKKER IS NOT A MOBILITY DEVICE. It is the user's responsibility to use this device with
caution. Furthermore, always take extra precautions when traveling on foot on roads designed for
motorized transportation.
