- Hi there!
-
- Is there any device that can help blind people locate objects by
- proximity?
-
- Years ago, a classmate of mine, worked on a project designing a
- kind of 'electronic cane' that, using ultrasound, would convert echo
- ranging signals into an audible sound whose pitch indicated the
- distance to objects. Pointing it in different directions it would give
- the user an estimate of distance to objects and help move without
- using his/her vision.
-
- The son of a friend of mine has recently lost his vision due to
- an unfortunate car accident (mother and sister died in the accident).
- The boy is only four and it seems not eligible to own or be helped by
- a seeing dog until is 18 years old.
- I think that a device like the one mentioned above may be
- helpful for this young and bright kid.
-
- I would appreciate any information as to whether devices like
- this are available commercially, or leads into research regarding the
- matter that can help me construct it. I am an electronic engineer
- with several years of experience in underwater acoustics
- instrumentation and am sure somebody must have worked out the
- details already for a design like this. Some people have suggested that
- Polaroid has a kit, ultrasonic range module that could be used. Any ideas
- where I could get it?
-
- Please forward your responses to my e-mail address:
- 'miguel@lamont.ldgo.columbia.edu'
- I would post a summary of the inquire.
-
- Thank you.
