Arms and Interventions

Arm Intervention/treatment
Experimental: Egress Badge Performance
Blind subjects are walked into a building to a specific location, and then are asked to find their way out of the building.
Device: Egress Badge
Egress Badge is worn by subjects who are asked to use the badge to exit the building. The badge indicates the direction of each exit sign on route to an exit.
No Intervention: Baseline Egress Performance
Blind subjects are walked into a building to a particular location and then asked to find their way out of the building.


Outcome Measures

Primary Outcome Measures :
  1. Time to Exit Building [ Time Frame: 30 minutes total, 15 minutes for each of two timed trials ]
    Subjects are walked into a building to a specific location and then asked to find their way out of the building. Time to Exit Building is measured. This is protocol is performed twice, and the times averaged to obtain the outcome measure.
