CHAPTER 1 Introduction Use of Braille has been declined because computers are easier for blind users to use, since they come with the screen readers [1]. With computers, they can connect to web and send emails and get more connected with their friends. This results in losing interest in Braille, and in losing skills to read or write Braille. The high cost of common Braille writers limits the usage of the devices hence the learning necessity to write Braille. At schools, students are still being taught how to read or write Braille using these devices, but they have to carry their heavy Braille writers in order to be able to learn. The use of Braille writers in the class is also problematic, because they are noisy. This brings out the need to make Braille more attractive for many users so that they can still train themselves reading or writing Braille. There has been a highly interest in multi-touch devices, by sighted users. However, due to interaction techniques that require the user to visually locate objects on the screen, these devices are still inaccessible by blind people [6]. 1
