SUMMARY:VRception: Rapid Prototyping of Cross-Reality Systems in Virtual Reality
DESCRIPTION:Cross-reality systems empower users to transition along the reality-virtuality continuum or collaborate with others experiencing different manifestations of it. However\, prototyping these systems is challenging\, as it requires sophisticated technical skills\, time\, and often expensive hardware. We present VRception\, a concept and toolkit for quick and easy prototyping of cross-reality systems. By simulating all levels of the reality-virtuality continuum entirely in Virtual Reality\, our concept overcomes the asynchronicity of realities\, eliminating technical obstacles. Our VRception toolkit leverages this concept to allow rapid prototyping of cross-reality systems and easy remixing of elements from all continuum levels. We replicated six cross-reality papers using our toolkit and presented them to their authors. Interviews with them revealed that our toolkit sufficiently replicates their core functionalities and allows quick iterations. Additionally\, remote participants used our toolkit in pairs to collaboratively implement prototypes in about eight minutes that they would have otherwise expected to take days.

SUMMARY:Towards Collaborative Learning in Virtual Reality: A Comparison of Co-Located Symmetric and Asymmetric Pair-Learning
DESCRIPTION:Pair-learning is beneficial for learning outcome\, motivation\, and social presence\, and so is virtual reality (VR) by increasing immersion\, engagement\, motivation\, and interest of students. Nevertheless\, there is a research gap if the benefits of pair-learning and VR can be combined. Furthermore\, it is not clear which influence it has if only one or both peers use VR. To investigate these aspects\, we implemented two types of VR pair-learning systems\, a symmetric system with both peers using VR and an asymmetric system with one using a tablet. In a user study (N=46)\, the symmetric system statistically significantly provided higher presence\, immersion\, player experience\, and lower intrinsic cognitive load\, which are all important for learning. Symmetric and asymmetric systems performed equally well regarding learning outcome\, highlighting that both are valuable learning systems. We used these findings to define guidelines on how to design co-located VR pair-learning applications\, including characteristics for symmetric and asymmetric systems.
