Computer Vision-Based Aid for the Visually Impaired Persons- A Survey And Proposing New Framework

ABSTRACT: Developing a tool for the visually impaired people is not a recently emerged problem. But developing a computer aided tool is a still developing area. The aim of all these systems is to help the user in navigation without the help of a second person. There are several works using computer vision techniques. But there is no existing method that help to solve the all basic needs of blind person .All existing systems are designed only for a specific purpose. In this paper, we propose new theoretical framework which combines the key aspects of some use full methods and added some extra capabilities for assisting the blind person. This new system may solve some of major problems of blind persons that are still existing. Also, we give a comparison and analysis of the current use full navigation methods, and identify some challenges which require further research and development.
