In response to the challenges faced by the blind and visually impaired, exacerbated by the increasing prevalence of screen-related visual impairments, this proposal aims to address the shortcomings of existing solutions. The proposed solution consists of a cost-effective and secure approach, featuring a suit equipped with sensors and motors, complemented by a mobile app. This integrated system enhances the navigational experience for the visually impaired, offering key features such as safe traversal in any environment, map-guided navigation, and timely warnings of highspeed dangers. The suit utilizes time-of-flight sensors and vibration motors to convey crucial information to users, including distance, direction, and warnings, through distinct vibration signals. The mobile app serves as a valuable supplement to the suit, providing features such as traffic sign detection and advanced map navigation [8]. This cohesive blend of innovative hardware and software components establishes a comprehensive solution, addressing the urgent need for effective, affordable, and technologically advanced tools for the blind and visually impaired amidst the era of widespread screen usage.
