'Fitbit' for the blind: Echolocation-based smartwatch aids sightless steps

The Sunu band smartwatch, designed for people with visual impairments, uses a sonar sensor to detect objects and people within a 15-foot range. When it does, it gently vibrates to alert the wearer, changing intensity as an object or person gets closer. Wearers can also customize it using an iPhone app via Bluetooth, adjusting for walking speed and to make buzzes stronger or weaker.

Sunu, a company based in Boston and Guadalajara, Mexico, will start shipping the devices for $249 to $299 later this month.
