Application development of augment reality in geometry topic based on multimedia learning cognitive theory

Learning environment rapidly changed in line with the development of industrial revolution 4.0. Augmented Reality is one of the newest technology in educational field. AR technology able a user to interact with both virtual world and real world, in real time. The learning of geometry topics need someone to have good visual skill. Thus, we invented inovation by using AR technology called GeoAR in order to give new dimension of geometry topics learning. The focus of this inovation is the latest ar tracker which is Combination Multiple Tracker. Findings show positives outcomes as the user felt satisfied by using the application.
