Supersonic Stick on the Wrist for Blind People
It’s common for blind people to carry a white cane to assist them when they go around town, but a new “Supersonic Stick on the Wrist for Blind People” concept is one that could help them do away with that. The device uses supersonic signals (what we call sonar) to send out signals and receive them when they bounce back, warning the user of oncoming danger through sound and vibrations, turning the user into a walking bat of sorts (since they use sonar too). The device is small enough to fit comfortably on the user’s hand, which is good news, since the user will be able to easily have it around at all times.
