Abstract: Increasing head rotation gain in virtual reality significantly enhances user exploration efficiency.Due to spatial constraints,users often need to perform extensive head rotations to observe the entire scene,which may sacrifice comfort.Therefore,applying head rotation gain enables wide-angle rotations in virtual scenarios,allowing users to comprehensively view the environment.We note that in exploring virtual reality scenes,users frequently need to look up or down,yet current research lacks sufficient focus on head rotation thresholds in looking up or down positions.Consequently,this paper focuses on the differences in head rotation gain among looking up,looking down,and looking straight,as well as exploring the comfortable head rotation threshold ranges after incorporating pitch angles.By designing virtual scenes that guide users to rotate their heads at various pitch angles and collecting feedback through psychophysical experiments,this study compares head rotation gains across different states.The results indicate that introducing pitch angles significantly affects users’ perception of rotation thresholds,with notable differences in comfortable rotation thresholds at various pitch angles.

Key words: Virtual reality, Redirected walking, Rotation gain, Head rotation at pitch angle
