Abstract

Visually impaired people need some aid to interact with their environment with more security. The traditional methods to help blind and partially sighted people to move around on foot are the white cane (or white stick) and the guide dog that is very expensive due the training process and maintenance. The white cane is a long stick that operates as a contact tool. It is useful to detect obstacles, stairs and curbs in the walking path while the eco of the typical sound originated when contacting with the floor gives average volumetric information to the user and also alerts other people in their walking path. Recent advancements in embedded systems have opened up a vast area of research and development for affordable and portable assistive devices. Unfortunately the cost of these devices, their size, intrusiveness and higher learning curve prevents the visually impaired from taking advantage of available devices.This paper proposes the creation of smart white cane for increasing the independency of visually impaired people which is robust, low cost and user friendly. This smart white cane incorporates various purposes such as obstacle detection, item locator, alarm system, altitude sensing, and voice messenger and so on. This intelligent stick allows greater mobility and safety
