An Empirical Study of Size Discrimination in Augmented Reality

Abstract

Existing psychophysical experiments show that size perception can influence the human identification of object properties (e.g., shape or weight) in augmented reality (AR). Some recent studies have revealed the detection threshold of object size in real physical objects. However, the users' absolute detection threshold of object size augmentation is not clear, which limits the further evaluation of AR design. In this paper, we present two two-alternative forced-choicebased experiments on size perception of virtual objects in AR to explore the detection threshold of size difference in object augmentation. Our experimental results demonstrate that the user's point of subjective equality (PSE) is 4.00%, and the size difference could be easily detected when the virtual object is larger than 5.18%.
