This paper proposes an educational smartphone applicaiton which usages augmented reality and GPS on a smartphone to lead a learner's experience, and which provides games on cultural properties to keep the learner's interests. The proposed educational app is based on Keller's ARCS model system. To acquire knowledge through experience by using a GPS on a smartphone, the learner solves problems on cultural properties located in which the learner stays and thus the learner can keep her/his interest and increase her attention. Also, using augmented reality gives encouragement and rewards to the learner, increases her confidence and satisfaction, and helps her/him continue learning.
