Design and Development of Navigation Guide for Visually Impaired People

Navigation guide for visually impaired alludes to frameworks that can help individuals with vision misfortune in safe navigation. This paper proposes a system to help these individuals in unfamiliar environment while walking. The proposed system can detect the obstacles around the individuals in the direction left, front and right using three infrared sensors. The system comprises of three infrared sensors, raspberry pi, power supply, and headphone. The overall performance of the system is evaluated in terms of accuracy and error rate. The average accuracy and error rate achieved by the framework are 98.99% and 1.006% for front obstacle detection. Finally, the system provides an audio signal to the user by means of a headphone that can help to avoid the obstacles in the way of walking properly.
