This paper explores user behavior in virtual reality (VR) environ-
ments, emphasizing the integration of idiosyncratic eye and head
gaze for optimal user experience. Analyzing a gaze-based view-
port control study dataset, we categorize users as head movers and non-head movers. In the study, participants were asked to align the viewport in VR so that a target is in the center. We tested three techniques: Controller Snap, Dwell Snap, and Gaze Pursuit, all using head and eye movement and showcasing particular behavioral patterns where some users prefer head movements, while others refrain from using head rotations for VR viewport control By that, our results point towards distinctive patterns of head- and non-head movers. The study highlights the need for personalized VR interfaces by considering these nuanced behavioral differences.
