Can a tactile wand help the visually impaired?

This is a smart wand that has been designed to replace the traditional long stick used by the visually impaired.

This wand was created by Jin Woo Han it uses a sensor on the front to detect nearby objects and provides feedback about how far away they are with varying levels of vibration.

The wand includes a tactile strip where you place your thumb that will actually indicate the position of objects around you.

Unfortunately the Tactile Wand is just a concept right now, and given the time needed to perfect the design and the thorough testing that will be required.
