Safe boundary / white stick for the blind

The blind use white stick to check their surrounding. They tap the ground and check their path. White stick is like their eyes.Design of mine was motivated by thinking that i want to keep their safe when they walk.We shoudn’t block their sight. Disturbing the can embarrass them. It is important to protect them. The Blind need a safe path day and night.‘Safe boundary’ have a laser point on the middle of it and laser‘s power button on the top of it. That laser point shows
blind’s right direction and the safe distance to people. It can help a blind to be safe.
And people understand what can they do for the blind.
