Smart Walker

Elderlies, blind or visually impaired people recur to a cane as a traditional ambulation aid. Although useful for maintaining balance, and for pivoting around obstacles, this tool limits the autonomy of individuals. In some extreme cases, using a cane leads to potential hazards, which can be detrimental to the health of the person relying on it. The aim of this project is to introduce a novel automated ambulation tool, entitled "Smart Walker", which overcomes the aforementioned disadvantages. The Smart Walker is equipped with an Android application that wirelessly collects relevant data (blood pressure, heart rate, position of obstacles, etc.) through sensors, and analyzes them. The processing is done in real-time via a pre-programmed Arduino board, the results are relayed back to the application installed on the smart phone, accordingly, the user adjusts his plan of action. The encouraging results set path for extending this work to be implemented in more aid-systems, a fact that is apt to improve the overall health and well-being of old and impaired people.
