Abstract
There is so many blind persons that use a blind stick to help their dally
walking or life. But the blind stick will be hit some person when the blind
stick waggling. So there is need to develop new walking stick that the
stick can be detected the obstacle stealthy. So the bat are the very best
object to learn at to stealthy detected the obstacle. From observe the bat,
we have a conclusion that use a ultrasound for the detected the obstacle is
a good way to do and the new walking stick is use ultrasound theory of
the bat perform by the microproccer and the electronic component. This
walking stick can be help the blind persons or the person hit by the old
waggling blind stick.

Aims
This Electronic Walking Stick for the Blind is use to help the blind person
to detect obstacle and depressions in front of him. After detect an object
in front of the blind person the Electronic Walking Stick will be sound a
the tone of warning signal and warning signal will change gradually when
the blind person get closer to the obstacle. Also if too close to the object it
will generate a vibration signal with the vibrator.
Scope
In our project, we will focus on the ultrasound propagation
technique, sound speed. And follow are the basic theory the
ultrasound propagation technique sound speed in the free air
Conclusion
The electronic walking stick is a portable electronic product; the power
consummation is mainly target to due with. But the transmit and receive
circuit will have a great power lost, it will power down when the blind
person that on the street, so the walking stick may need to design less
power lost and indicate the blind person to change their battery when it
was too late.
