Smart Glasses Help Blind Navigate

"Smart specs for the blind" from New Scientist reports on smart glasses that give audio clues to the blind about objects that are moving and may not be detected by a long cane.

A pair of spectacles fitted with a camera and accelerometers that detect movement can, however. They are connected to a computer that spots any obstacles in the field of view and works out which are moving.

The specs provide audio signals to the wearer to let them know what's happening around them, and which objects are moving, so they can navigate without bumps. The system was dreamed up by electronics company Philips.
