Review Paper on Smart Guidance Belt For Blinds

This project seeks to create a simplified version of a smart wearable belt that can assist blind people with navigation, using a sensible and compact design for the electronic equipment. The design includes an embedded system, and could potentially incorporate machine learning algorithms to detect potholes and other irregularities on the road. The goal is to develop a smart belt that can help blind people travel independently without the use of a cane. The Electronic Blind Mobility Aid is a technology that uses sensors put on a belt worn around the waist to allow blind persons to travel independently. This advanced technology can help many people with visual impairments to travel independently. Blind people often face obstacles that can make it difficult for them to travel alone, but a blind belt can extend their range of perception by serving as an obstacle detector. Visually impaired people often use their hearing to compensate for their reduced eyesight, and can recognize sound sources. This technology enables blind persons to travel independently and receive obstacle alerts via headphones and speakers using sensors installed on a belt that is worn around the waist. Blind people can utilise this approach every day to find potential hazards, roadblocks, and pathways. In the end, this technology will serve to increase the independence of blind individuals and give them more confidence when they travel. To notify users of potential dangers, the device has a buzzer that produces vibration signals and emits a warning sound. Both the sound frequency and the vibration frequency rise as the space between the elastic gloves and the barriers gets smaller. The design incorporates a buzzer and motor in addition to the capability to notify the proper person in case of an emergency.. The goal of this study is to provide a low-cost, effective means of helping blind individuals travel more easily, quickly, and confidently. This design provides a quick-response, cost-effective, and portable solution. This device can let blind persons traverse their environment more safely and confidently by employing sound and vibration cues to notify the user of impediments.
