Help for visually impaired

Researchers from the University of Southern California have developed a headset to help people with visual impairment in important everyday tasks such as navigation, route planning and object finding.

The device uses mathematical algorithms to convert real-world images into pixels, which are then projected onto a screen in front of the wearer. Blinking dots at the side of the display can provide participants with additional directional clues where needed.

The researchers found that, when directional cues were sued, participants head movements, time to complete tasks and numbers of errors reported were all significantly reduced.
