Design and implementation of mobility aid for blind people

With the scope of electronics increasing day by day, the need for utilizing these advanced technologies to make human lives simpler is becoming more and more necessary. The demand for using these technologies to make lives easier for disabled people is also increasing. This has prompted many new areas of research and one of the areas is electronic mobility aid for blind people. According to the World Health Organization, approximately 285 million people of all ages are blind, which is significantly a large number [1]. Traditional mobility aids include the white stick and the guide dogs which take a lot of time getting used to. There are a few smart systems available in the market which uses electronic sensors mounted on the cane but those systems also have certain disadvantages. This paper analyses the available solutions and proposes an entire new approach to solve the above problem. The new approach not only eliminates the disadvantages of the existing solutions, but it also is reliable, cost effective and most importantly easier to use.
