Public Transport Assistant for Visually Impaired (PuTAVI)

Abstract: Visually challenged people rely on support for managing their routine, be it in crossing busy roads, climbing steps or boarding buses. Applying technology to make these people self-reliant and independent is a social responsibility. It is high time that a novel technological solution be found. The objective of this project is to provide technologically supported audio guidance system to visually challenged people, with respect to obstacle and bus identification on an MSP430 platform making use of ultrasonic sensors, RF Transmitter and Receiver. The system is wearable by the user and user friendly in its interface.
