Why is it better than just simple wand? Othewise it is ugly. Nice try but please do it again. Please meet with real blind people not a gamer.

Haha don't be serious~! Thank you for your comments. I've worked it 3years ago during school period. Sure, it has many problem, but I won't it again. Blind wand have not been designed for it's shape but a research for a blind people; such as how they feel about their enviroment, how they recognize the world. I would like to give them to feel the enviroment indirectnessly.
