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, emits a high-frequency sound wave that bounces off of objects that the user encounters. The resulting vibratory pattern changes depending on how close or far away the object is to the user. Sunu band augments awareness of the user’s personal space, reduces unwanted accidents and ultimately improves confidence while providing a more fluid and enjoyable mobility. 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.
