Bats & Helping The Blind
It is sort of ironic that we’ve used bats as the animals that inspired scientists to create technology for the blind. Considering bats themselves are basically blind, as their eyes are incredibly sensitive to light. Thus, they have to be in darker conditions to see properly. They actually get around using echolocation through ultrasonic echoes. This is what allows the bats to “see” around them, avoiding obstacles or possible predators. This same method was utilized in the Ultracane. Sensors are all over the cane to make it sensitive to the world around it. The cane allows blind people to sense objects higher than their own height and avoid far more possible dangers.
