DESIGN AND IMPLEMENTATION OF A SINGLE PIPELINED FULL POSIT PROCESSING UNIT BY USING RISC – V

Abstract

Blind mobility is one of the major challenges encountered by visually impaired persons in their daily lives. The loss of eyesight significantly restricts their independence and ability to navigate safely. Traditionally, they rely on white canes, guide dogs, or their accumulated spatial memories. However, these methods have limitations, especially in unfamiliar or dynamic environments. The main objective of this work is to develop a low-cost, reliable, portable, user-friendly, low-power, and robust solution to assist visually impaired individuals in smooth and safe navigation.
This project introduces an innovative assistive technology in the form of smart glasses, integrated with multiple sensors and communication modules to enhance safety, mobility, and independence. The system primarily employs ultrasonic sensors to detect obstacles in the user's path, providing real-time feedback through buzzer alerts. Additionally, a secondary ultrasonic sensor is embedded in a walking stick to detect open manholes or other ground-level hazards, reducing the risk of falls and injuries.
To further improve user safety, the system incorporates a panic button that, when activated, triggers the GPS and GSM modules. This feature sends the user’s real-time location to pre-registered emergency contacts, ensuring immediate assistance in critical situations. Moreover, a buzzer is included to attract nearby individuals' attention during emergencies, offering an additional layer of security.
The proposed solution is designed to be lightweight and comfortable for daily use. It operates on a low-power system, ensuring extended battery life. Unlike traditional mobility aids, this system leverages modern technology to provide an intuitive and efficient navigation experience. By integrating smart wearables with real-time hazard detection and emergency response features, this project aims to significantly enhance the independence and confidence of visually impaired individuals.
