摘要
Abstract Blindness is a condition in which a person loses their ability to see because of physiological or neurological issues. This paper suggests a smart blind stick that uses modern technologies to make traveling easier for visually impaired people. Ultrasonic, light, water, and height sensors are used in the blind stick. An ultrasonic sensor is used to identify obstacles ahead of blind people. In addition, water sensors detect the presence of water and leaks when deployed in regions. One ultrasonic sensor is placed on the walking stick to classify the height of a barrier. An LDR is used to provide information about day and night. It also has GPS to help blind people track their location. Furthermore, a voice recognition system was employed to deliver the message by the human voice. Its height can be adjusted easily. After understanding customers’ demands, some ideas are added to create a product prototype. A cost analysis has been conducted, and it is discovered that mass production of the product is quite profitable. The smart blind stick is a low-cost, fast, and easy solution for blind and visually impaired people in third-world countries.
