Learning Environments in AR: Comparing Tablet and Head-mounted Augmented Reality Devices at Room and Table Scale

This paper presents work to examine how presentation scale and device form factor may affect learning in augmented reality (AR) en-vironments. We conducted a 2 (form factor) x 2 (scale) experiment in which 131 participants explored an AR learning environment using either tablet AR or a Hololens2 crossed with either full room scale or at table scale. Dependent variables measured participants declarative knowledge about information acquired in the environ-ment as well as their understanding of spatial layout. Initial analysis suggests comparable outcomes across all manipulations with respect to acquiring declarative and spatial knowledge.
