I know that many blind people including myself depended greatly on finger
snapping and/or clicking to get information about our surrounding
environment when we were kids. The use of a cane reduced the need to
generate sounds, but we were also discouraged from generating sounds as
it was seen to be inappropriate. Yet, as an adult, I still find an
occasional situation when generating a sound that yields echos, whether
it be a tapping cane or jingling keys, is most useful.
However, one of my gripes with some of the travel aids that have been
suggested is the way they appear. Therefore, I guess, one must examine
the social implications of any device that we would intend for wide use.
Also, as I have said before, one more device to carry that needs
batteries may not go over. --
