Paper accepted to CHI ’20

We are very happy to announce that we had a paper accepted to The ACM CHI Conference on Human Factors in Computing Systems, the premier international conference of Human-Computer Interaction. This year’s acceptance rate was 24%.

Our paper by Sarune Baceviciute, Aske Mottelson, Thomas Terkildsen, and Guido Makransky, entitled Investigating Representation of Text and Audio in Educational VR using Learning Outcomes and EEG investigates how different learning content representations in virtual environments affect the process and outcomes of learning. Find the abstract below (the paper will be published in April 2020).

Abstract
This paper reports findings from a between-subjects experiment that investigates how different learning content representations in virtual environments (VE) affect the process and outcomes of learning. Seventy-eight participants were subjected to an immersive virtual reality (VR) application, where they received identical instructional information, rendered in three different formats: as text in an overlay interface, as text embedded semantically in a virtual book, or as audio. Learning outcome measures, self-reports, and an electroencephalogram (EEG) were used to compare conditions. Results show that reading was superior to listening for the learning outcomes of retention, self-efficacy, and extraneous attention. Reading text from a virtual book was reported to be less cognitively demanding, compared to reading from an overlay interface. EEG analyses show significantly lower theta and higher alpha activation in the audio condition. The findings have important implications for the design of educational VR environments.
