Wearable sonar technology to guide sight impaired

Using radar and augmented reality, Sunu Band enables people who are low vision and blind to travel with confidence. Advanced haptic feedback guides the way around any obstacle, and navigation sensors connect to the world around the user. For more information see the IDTechEx reports on digital health and wearable technology.
Sunu band is a sonar smartband that improves navigation for the visually impaired. Sunu band combines sonar or echolocation with gentle precise vibrations to inform the user about objects or obstacles within their environment. The band augments awareness of the user's personal space, reduces accidents and ultimately improves confidence while providing a more fluid and enjoyable mobility.
The band emits a high-frequency sound wave that bounces off of objects that the user encounters, and the resulting vibratory pattern changes depending on how close or far away the object is to the user. Specifically, the users feel vibration pulses on the wrist that become more frequent as an object is close or less frequent as the object is farther away.
Users of Sunu Band wear it in conjunction with the cane or guide dog to augment awareness and complement mobility by detecting obstacles to the body and head in a way that's discreet and unobtrusive.
  • Complementary mobility aid will detect upper body obstacles from knees to head up to 15 feet ahead.
  • Hands free. Since users do not need to hold or carry it in their bag, full of devices. Once on the wrist it is ready for use and includes smart gestures.
  • Powered by a Mobile App, adjust Sunu Band settings to those preferred and update Sunu Band firmware when needed.
  • Simple interface. With just 2 side buttons and a sensitive touch pad learning Sunu Band functionality is easy and fast.
  • Sonar sensor differentiators adjust sonar waves for indoor or outdoor, intensity of vibrations and edge detector. When walking through doorways or around corners, the edge detector provides a different haptic sensation that help the wearer locate the edge precisely.
  • Place finder/explorer and GPS navigation app, although the band will still function without use of the app.
