Supporting independent indoor travel of people with blindness and intellectual disability with reduced frequencies of auditory cues

This study evaluated the feasibility of supporting independent indoor trave l using reduced frequencies of auditory cues with two persons having total blindness and profound intellectual disability. For these persons. who had acquired satisfactory travel performance with cues occurring every 8 sec., the cue frequencies were reduced to one-half or one-third of the original l evel. Analysis showed that both participants could manage accurate travel u nder the nea cue conditions, even though their travel time (efficiency) see med negatively affected. Implications of the findings were discussed.
