Space, a central frontier - the role of spatial abilities when learning the structure of 3D AR objects

Learning about three-dimensional (3D) objects is the focus of many augmented reality (AR) applications. Although this underlines the importance of spatiality in AR experiences, learners' spatial abilities should be considered in this context. While spatial abilities may compensate for the lack of spatial information in 2D representations (ability-as-compensator hypothesis), they may also be necessary for learning with 3D representations in the first place (ability-as-enhancer hypothesis). In the current study, we examine the role 3D spatial visualization abilities and 2D spatial memory abilities may play when learning with 3D AR objects. Both variables were measured in an exploratory pilot study in which N = 33 participants learned about the spatial structure of the modules of the International Space Station (ISS) with either an AR or a non-AR mobile application. We found that spatial abilities indeed had moderating effects on achievement in the learning task and knowledge test, although the results are inconclusive concerning an ability-as-enhancer or -compensator hypothesis. We discuss the results and conclude that it is necessary that researchers take a closer look at the role of learners' spatial abilities when learning with 3D representations in AR. With additional insights, practitioners can then make informed decisions on using AR applications.
