A Smart Walking Stick

Abstract

Recent advances in technology have enabled elderly citizens to access and utilize a broad variety of services to facilitate their independence. This paper introduces the smart walking stick using ultrasonic sensors and Arduino for the visually impaired. The visually disabled individuals usually rely on the help of other people, trained dogs, or specialized electronic appliances as decision-making support systems. We shall provide an illustration of how to develop and use a model that will assist patients with mild Alzheimer's disease and the elderly. There are many features added into this it a clever stick. Designing smart products that make it possible for elderly individuals to walk freely is the main aim of. We did this by incorporating ultrasonic sensors at certain locations into the can which gave information regarding the environment to the user by triggering the buzzer sound. We suggested low cost and light weight system based on microcontroller which processes the signal and warns the  visually challenged individual across any hurdle, water or darkness using beeping signals. Whether at home or outside, there needs to be a proper gadget to help the elderly walk freely and safely. As compared to the commercial walking belts, these walking sticks have been tested to confirm all the factors that are vital for the elderly to reclaim their confidence and enhance their mobility are operating. Our device can detect obstacles within the distance of about 3m from the user.
