In contrast, for TL only one trial required a restart. The implication of this finding is twofold. Thus the analysis of travel times above incorporates the restart measure. Thus disorientation is unlikely. Talking Lights is quite note-worthy.
Verbal directions are only available to blind people if other people are present.
Additionally, the routes and verbal directions used here were relatively simple and short. Longer routes and directions would presumably impose memory loads sufficiently high to result in travel disorientation and more restarts, a pattern of results beginning to emerge in the present data as noted above. The transceiver system using conventional fluorescent lights to transmit verbal information for wayfinding enabled blind users who were blind to travel indoor routes with no need for individual assistance.
