Smart Blind Stick

Abstract

In accordance to World Health Organization statics, 253 million people are currently living with vision impairment, 36 million of which are blind, and 217 million who have moderate severe vision impairment.  Mostly people aged 50 and above are blind as WHO estimated that 81% of the blind population are adult peoples. Due to a variety of factors, number of visually impaired persons is anticipated to rise in the future. As a result, there is a demand for a low-cost technology that blind individuals can use to walk more freely and pleasantly. It is critical that a smart solution for blind people be proposed so that they can use it in their daily lives. If you notice them, you'll realise that they can't walk without the assistance of others. To get to their destination, one must seek assistance. They have to deal with additional difficulties in their daily lives. It becomes impossible for a visually impaired person to carry out his or her daily tasks. A person can walk more confidently with the help of this blind stick. This stick detects the object in front of the user and responds by vibrating or issuing an instruction to the user. As a result, the person can stroll without worry. This device will be the most effective way for them to conquer their problems. The Smart Blind Stick can assist vision impaired people in moving about and performing their tasks.

The smart stick will have sensors integrated in it, which allows it to detect things/intruders. If any objects or obstacles come within range of an ultrasonic sensor, the person will be warned with a short response time via a vibrator and buzzer. The total system also includes a GPS module, so that if a person becomes lost, a well-wisher can find out where he or she is by sending a help message that includes the latitude and longitude in the form of a link. This system also includes a water sensor and an LED light at the bottom of the stick. The project's major goal is to design a cost-effective and efficient blind stick.
