Review on Real Time Multi-Utility Shoe for Visually Impaired Persons using Internet of Things

Making physical objects talk to one other or to people is the core idea behind the internet of things. It is an information technology that is expanding and developing quickly. The creation of assistive equipment is necessary due to the rise in the population of persons who are blind. This issue can be resolved by using a tool that acts as an intelligent guide for blind individuals. Our idea is to help blind people carry out their daily tasks, especially navigation. It is constructed utilising Internet of Things technology, and the shoe will have several sensors, a microcontroller, and a panic button incorporated in it. When the wearer steps in front of an obstacle, the shoe alerts them by sounding the panic button. Ultrasonic sensors are used for obstacle detection, and Bluetooth sends a voice command when an obstruction is found. Moisture sensor warns of slick surface. In order to locate the blind for simple tracking and to send an SMS to the guardian in case of emergency, the system uses GPS and GSM modules. To prevent the user from running into any obstacles in his path, the smart shoe collaborates and interacts with one another. It will also be helpful to use GPS to locate the person in real time and measure their temperature and heart rate. The device's main objective is to give blind people a simple and practical navigational tool that enables artificial vision by providing information about the environment and the static and moving objects nearby.
