Sunu Band combines sonar or echolocation with gentle precise vibrations to inform the user about objects or obstacles within their environment. Sunu Band augments awareness of the user’s personal space, reduces accidents and ultimately improves confidence while providing a more fluid and enjoyable mobility.
