“…Several studies have suggested the following as contributing to simulator sickness: age (Reason & Brand, 1975), gender (Hein, 1993), prior history of simulator sickness (Braithwaite & Braithwaite, 1990), head movement (Moss, Scisco, & Muth, 2008), body movement (Bouyer & Watt, 1996), image scale (Draper et al, 2001), and latency (DiZio & Lackner, 1997), which is the focus of this article. From a physiological perspective, latency with HMDs is the time from user input (head motion) to corresponding feedback (visual perception) of the updated HMD imagery and results in apparent latency that is visually perceived by the user.…”
