Reducing Cybersickness for 2D VR Spectators Using a Gaze-Based Stabilized Third-Person View

Abstract

While motion sickness in VR has been widely studied for HMD (head-mounted display) wearers, the experience of external spectators watching VR content on 2D monitors has received relatively little attention. This paper proposes a gaze-based stabilized thirdperson view that adjusts the spectator camera according to the HMD gaze behavior of the HMD wearer. Through a repeated measures experiment using the Simulator Sickness Questionnaire (SSQ), we show that the proposed view reduces cybersickness experienced by spectators watching VR content on 2D monitors, compared to conventional first-person and third-person spectator views.
