K. Baerlocher,R. Gitzelmann,B. SteinmannThis chapter constitutes a summary of a few physical principles which can have relevance to the production of guidance prostheses for the blind. Mention will be made of several which perhaps warrant further consideration for special circumstances.

On Mobility Aids for the BlindI will briefly summarize the results of some 20 years of research at the Smith-Kettlewell Institute of Visual Sciences which I have directed toward the development of mobility aids for the blind. I will attempt to point out what we can learn from these investigations that may prove valuable in directing the thrust of future developments.

A Review of Mobility Aids and Means of Assessment tends to warn other pedestrians to get out of the way. The former feature requires fast stopping reaction when an obstacle is encountered, while the latter does not add to the grace and independence of travel.
