Similar to the way bats use sound to find their way, this wearable device uses ultrasonic tech and sonar tracking to help the visually impaired perceive objects ahead. Currently seeking finances via a crowdfunding campaign on Indiegogo, Sunu heightens perception, simplifies navigation and improves the lives of blind people.
The system consists of a band that uses haptic feedback and ultrasonic tech to detect objects in the wearer's vicinity. The Sunu tag can be clipped onto a keyring or onto a person. It acts as a beacon and can be tracked with a smartphone. Sunu lets the wearer follow their guide with more ease, find lost items and includes a built-in sensory alarm clock.
Together, these two gadgets can increase mobility and independence for those with vision problems.
