User Behaviour Analysis of Volumetric Video in Augmented Reality

Augmented reality (AR) is getting popular, and among other content creation techniques, volumetric video allows to bring dynamic real world content as captured by cameras into such applications. To develop efficient algorithms for compression and transmission of the volumetric media, it is important to understand how users will consume this new form of dynamic 3D content. In this paper, we analyse the user behaviour for the volumetric video consumption in AR. In particular, we study the distribution of users’ viewpoints, relative locations, and average distances from the content. For this purpose, we built an Android AR application using the volumetric video and conducted a user study remotely. The results show that users spent most of their time looking at the frontal part of the volumetric video, and this indicates the importance of the face in visual attention. The collected user behaviour data are made public to support further research.
