Hello:
I can see some possibilities for this type of device. At one of our R&D meetings,
the idea of an electronic dog guide was discussed. Another use would be for those
who are in wheelchairs. I haven't tried it very much but using a cane from a
wheelchair is quite a trick. Maybe more light or radio waves
will be shed on this subject.
