Design and implement a mobile-based system to teach traffic signs to illiterate people

Abstract Nowadays, most information and communication technologies target literate users and neglect the 800 million illiterate individuals around the world. Although there have been several attempts to develop systems that help illiterate people and try to reduce the digital gap between them and those who are literate, it is still challenging to find accessible systems for illiterate people. This research aims to reduce the digital gap between illiterate and literate people in Iraq through developing a mobile application for learning traffic signs. Firstly, a requirement elicitation study was conducted to explore a set of design considerations and build an accessible interface for illiterate people. The study resulted in several design principles, such as using voice instructions, focusing on graphic content, and using the local language. Then, the mobile application was developed based on these design principles. Finally, an evaluation study was conducted to measure the usability of the developed application. The results revealed that the built application is efficient and effective, and the users were extremely satisfied in several aspects, such as easy usage and learnability, and declared that they would use it in the future and recommend it to others.
