Different Types of Interaction with Augmented Reality Learning Material

In this paper, a study with the focus on interactivity in augmented reality (AR) applications concerning the influence of different forms of interaction with AR learning material is presented. While research on multimedia learning often distinguishes between mental and physical interaction with learning material, other research fields state that physical interaction is necessary to interact mentally. To look at how this distinction may play a role in AR-based learning material, an experimental study with a 2x2 design manipulating mental and physical interaction was conducted, including learning material on the topic of power plants. The data (N = 128) were collected and analyzed, showing that, although not expected, learning was better in groups in which either more physical or more mental interaction was applied, but not in groups in which both were high. The results are discussed under the potential idea of cognitive overload.
