IoT Based Smart Blind Walking Stick

 IoT Based Smart Blind Walking Stick

Our society has a large population of visually impaired people. If you notice them, you will know they cannot walk without help; they need guidance to reach their destination. They face 

many struggles in their daily lives. Even though technology is advancing rapidly today, there is no affordable device available for people with visual impairments. Blind people have difficulty performing their daily activities, so a IoT based Smart Blind Stick was designed to help them move and perform their tasks more easily. However, when visually impaired people are walking on the road, they find it difficult to see obstacles along the way, which makes it very dangerous. A smart stick is one of the best ways to point around. This stick is equipped with infrared sensors to detect stair cases, and a pair of ultrasonic sensors to detect any other obstacles in front of the user, within a range of four meters. A water sensor is also used in the system, which detects water on the user’s path. All found obstacles are alerted to the user through a buzzer. 

A person’s eyes are an important organ, as they process visual information and transmit it to the brain; also, because people receive and process 83% of information from their environment through their eyes, eyes play a crucial role in the lives of humans. Many people are deprived of this information, however. There are a number of severe disabilities, such as blindness, in which a person must face many challenges despite technological advancements. Blindness refers to a condition in people lacking the ability to perceive light, as well as those who have so little vision that they must use other senses as substitutes for their ability to see. The visually impaired refers to a person with complete or partial blindness. According to a file from the World Health Organization (WHO), an estimated 253 million human beings are dwelling with imaginative and prescient impairment, out of which 36 million are definitely visually impaired and 217 million have reasonable to extreme imaginative and prescient impairment.
