Abstract: Two experiments were conducted to determine participants' accuracy in locating targets using the BrailleNote Global Positioning System (BGPS). In the first experiment, 19 participants located a 25-foot chalk circle 93 percent of the time with the BGPS, compared to 12 percent of the time without it. The second experiment, designed as a follow-up to the first, tested how close experienced user could come to a known target point using the BGPS. Results showed that the subject came within 1 foot of the target on all trials. Target location techniques are described.
