Designer Jin Woo Han has crafted a Wand for the Blind, that makes the classic white stick redundant. Although still a concept, the wand efficiently deters the user from banging into obstacles. The wand has the ability to sense objects around from a distance via the embedded sensors. It can help the impaired person develop their tactile senses. It raises an alert beforehand so that the person can avoid the obstacle.
