Student can learn in fun way through multimedia usage. There are several objectives to implement this research. Those are to identify which topic in Form One Geography Textbook is suitable to be implement in augmented reality concept, develop an augmented reality application that can help students recognize the name of states in Malaysia, location of states in Malaysia map and other details regarding each state in Malaysia through an interactive way and, evaluate usability of the application. This research uses quantitative method. The research approach is survey. About 15 students that are studying Geography subject in Universiti Pendidikan Sultan Idris (UPSI) are involve as sample through quota sampling. Overall, Pocket Malaysia is a good starting point for Geography subject in secondary school. This is because not many AR applications today are focusing on Geography subject.
