Blind walking stick with sensor.

The blind stick is integrated with ultrasonic sensor along with light and water sensing. We have created designed and built an ultrasonic blind walking stick device which will help blind people to walk with ease independently. This smart stick will have an ultrasonic sensor to sense distance from any obstacle ldr to sense lighting conditions and a rf remote using which the blind man could remotely locate his stick. For better accuracy and assistance two or three sensors can be used.

In this project we will learn how to design blind. To design blind walking stick using. On sensing obstacles the sensor passes this data to the microcontroller. One of the main features of the light stick is its obstacle sensor that alerts users of objects ahead of them.

Currently in order for a blind person to navigate any given publicly accessible building they. As a simpler version we have used only one ultrasonic sensor in this project. All the feedbacks will be given to the blind man through a buzzer. Also we use a sorting system to detect water in.

Through this the blind person can aware about the obstacles in front of him. This stick makes life much easier for those who are blind by power packing a regular walking stick with helpful technology. A young research scholar from the applied mechanics department of motilal nehru national institute of technology mnnit has designed a sensor based high tech walking stick for blind persons. The light stick was designed by wu guanghao and is the ultimate walking stick for the visually impaired.

Sajal babu the research scholar who has developed this stick under the guidance of professor ravi prakash tiwari has named it smart blind stick. The smart blind stick automatically detects the obstacle in front of the person and give him a response to the person by vibrating the stick and also with a warning sound. This electronic walking stick is revolutionizing the way that blind people can navigate the world.
