Abstract

An application named “BTbrailleCal” based on Android smart phone is designed to help visually impaired students (VIS) in calculating numbers. This paper describes a user interface with an easy-to-distinguish layout that enables VIS to interact with touch screen on the smart phone. Vibration feedback and audio feedback will be provided to the user regarding their input. Additionally, the paper illustrates the Braille method specially details about math Braille. Paper prototypes are created at the beginning and then the final design is done by using the designing software “Pencil”. This educational application will assist the visually impaired students to solve their mathematical problems.
