Miniguide US

Miniguide US

The Miniguide US is a tiny, hand-held electronic travel device that can enhance the effectiveness of a blind person's primary travel method. The Miniguide US uses ultrasound to detect objects, and gives tactual or auditory feedback by vibrating or chirping more rapidly as you approach an object. Ideal for use by deafblind persons.

When used with a cane or dog guide, the Miniguide US can help a blind person avoid obstacles and overhangs; locate landmarks; locate items such as mailboxes or trash cans; and find open paths through crowds at ranges from 20 inches to 26 feet depending on the size of the object.

NOTE: The Miniguide US should be used along with a sighted guide, dog guide, or cane because it does not detect drop-offs and does not provide sufficient information to ensure safety.
