Smart Blind Stick With Ultrasonic Sensor Abstract

With this in mind let us use the power of arduino and simple sensors to build a blind man s stick that could be a lifesaver for visually impaired persons.

Smart blind stick with ultrasonic sensor abstract. We here propose an advanced blind stick that allows visually challenged people to navigate with ease using advanced technology. Ultrasonic sensor sends high frequency pulses these pulses reflects from object and takes as echo time between echo and trig is measured by the microcontroller or arduino which is. The smart stick is built on arduino pro mini. Person suffering from night blindness cataracts glaucoma albinism or injury.

The stick uses ultrasonic sensors for obstacle detection. Presented here is a smart stick using arduino uno. This paper reviews the design of a smart cane i e a smart stick for the blind equipped with obstacle recognition using ai technologies adds more virtual. I used ultrasonic sensor for detecting the obstacles.

It cost me just 10 to make one. The technology can indeed neutralize human disability. Sometimes even when they use this stick there is no guarantee that the blind persons are safe and secured in. Abstract the purpose of this paper is to design construct and do a performance test of a smart walking stick with object detection and recognition.

Obstacle detection is one of the major concerns for a fully or a partially blind person e g. An ultrasonic sensor is used for object. 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. The blind stick is integrated with ultrasonic sensor along with light and water sensing.

Blind stick is an innovative stick designed for visually disabled people for improved navigation. It is well known that the blind people carry a hand stick with them whenever they need a support. An ultrasonic sensor will be installed in a stick which will sense the distance of a person from any obstacle an ldr to. Smart blind stick with ultrasonic sensor abstract.

The main aim of this project is to assist the blind persons without the human need. Through this the blind person can aware about the obstacles in front of him. Of course you can use a vibrator motor in place of buzzer and advance a lot more using your creativity. 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 all the feedbacks will be given to the blind man through a buzzer.
