ultracane
This ultrasonic cane is a “radar” for the vision-impaired.
Via gizmag

The Ultracane send signals that will bounce off and come back to it, like a radar. The bounced signals will be converted into vibrations that will indicate to the users what is surrounding him or her. It’s not very far from being DareDevil…

The cane has been getting a lot of good reviews from people who tested it.
