A visual orientation system was employed for promoting independent indoor travel for two young adults with profound developmental disabilities and visual impairment. The system was a portable device subjects wore and light sources that marked the routes to the various destinations. Data showed that the system was useful in helping the subjects orient and move independently in their daily environment and in a new (generalization) setting. The visual orientation system is discussed in relation to other systems previously developed.
