Visualization for increased understanding and learning using augmented reality

Augmented reality allows the superimposing of computer-generated images over real scenes in real time. This paper describes a project in which an interactive solar system was developed to help middle school students in the sciences understand spatial concepts using augmented reality. The marker-based augmented reality application works by using a camera to read a marker, then calculates the camera position in 3D space, and superimposes the solar system. With a webcam and a laptop, augmented reality application development is highly accessible. The visualization application research detailed here will be used for formal pedagogical research examining whether students benefit from this method by conducting both pre-event and post-event assessment surveys. The surveys will gather valuable feedback from middle-school science students concerning whether the augmented reality method is effective for teaching and learning. Preliminary feedback from students and educators indicates that this visual teaching method is effective.
