While the act of walking down the street might be second nature to most of us, it can be a much more difficult experience for those who are blind or visually impaired. To combat the issue, Microsoft has developed a headset that uses bone-conducting audio, creating a 3D soundscape to safely guide users to their destinations.
Microsoft developed the device, currently in the prototype stage, with the help of the Guide Dogs charity (and it was adapted from an existing Aftershokz headset for cyclists). Rather than using conventional audio, sound is conducted through the jawbone directly into the inner ear, meaning wearers can still hear what’s going on around them.
The headset connects to Windows Phone handsets, and uses a combination of GPS and annotated maps alongside a network of Bluetooth and Wi-Fi beacons placed along the route. After setting the route, the wearer will hear a continuous clicking noise designed to sound like it’s coming from a meter or two ahead, guiding him or her along the correct route.
Different audio cues will warn the user if she’s approaching obstacles such as curbs or parked cars, and simple instructions such as “turn left” will direct them on their route. The experience is designed to replace sticks or canes, providing a less stressful means for visually impaired people to safely navigate outside.
