The phrase 'Blind as a bat' is misleading. All bats can see but many rely on echolocation to bounce sounds off an object, including prey, to determine its size, shape, and location. The ultrasonic waves that bats use have now been incorporated into a piece of technology to help blind people. The cane senses and vibrates as it nears objects, enabling the user to detect and negotiate obstacles in their path. This video shows the cane in action.
