Brailler: Enabling the visually impaired to use smartphones

Abstract

With the increase in the number of smartphone users, it is increasingly important to make the smartphones accessible everyone. Most smartphone have a touchscreen interface, which makes it even more difficult for the visually impaired to use it since it does not provide tactile feedback. According to the World Health Organization (WHO), 284 million people are visually impaired worldwide. It is very important that we make it easier for such a huge population of the world to be using their smartphone devices just like any other user. This paper presents a working prototype solution for enabling the visually impaired to use smartphones.
