PDF: On Head Movements in Repeated 360° Video Quality Assessment for Standing and Seated Viewing on Head Mounted Displays

Abstract

Watching 360° videos on head mounted displays (HMDs) allows viewers to explore scenes in all directions. In this paper, we focus on investigating the head movements of two participants for standing and seated viewing of a total of 720 360° videos on HMDs. The head movements were recorded in a 360° video quality assessment experiment which was repeated after a long and short break between sessions to study changes in viewing behavior over time. The analysis of the head movement data is provided as histograms of head rotations, head speed, head turns, and head trajectories. It is shown that the participants have their own distinct exploration behavior for standing viewing which becomes less different for seated viewing.
