Microsoft is collaborating with Guide Dogs for the Blind and AfterShokz on Cities Unlocked, a prototype headset, smartphone and navigation system for the visually impaired.
The technology helps a user find his/her way, describes potential hazards, such as low-hanging trees, and highlights attractions, including restaurants, on the route.
The headset uses bone-conducting audio that does not cover the ears, ensuring that the wearer hears traffic noises and can have a conversation. It rests in front of the ear and it uses Bluetooth signals to transmit cues into a series of clicks, beeps, and voice notifications.
