An Advanced Multimodal Navigation Perception System for the Visually Impaired

Technological innovation continues to advance at a rapid pace, enhancing and streamlining people's lives. The Secure navigation of surroundings and upholding a sense of independence provide considerable obstacles to the visually handicapped. Visually impaired People have trouble detecting barriers in their path, when strolling down the street, which causes it hazardous. The development and implementation of a multimodal navigation system with the goal of enhancing accessibility and independence for people having visual impairments are the main topics of this research. In order to provide the user with real-time information about the environment, the suggested system integrates a number of technologies, including computer vision, sensor fusion, localization, and haptic feedback methods. In this paper, we propose a solution called Visually Impaired, which uses interdisciplinary fields like software engineering, gadget design, and health science to help visually impaired people explore quickly and confidently by using ultrasonic waves to track nearby obstacles and alert them with a signal speech warning message and buzzer. Smart multimodal navigation perception system with an ultrasonic sensor that can detect stairs and other obstacles in its path to the front left, and right. Within a range of 0 to 30 cm, impediments are detectable. This project's use of an ultrasonic sensor is crucial. GPS stands for Global Positioning System. It has been made simpler for a blind person to use Google Maps to find a lost person thanks to the use of GSM modules and Global System for Mobile Communication (GSM) technology. The smart stick is affordable, quick to react, power-efficient, and portable. This smart stick makes it easy for blind people to move from one location to another.
