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

Abstract

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.
