Passive watching of a virtual reality game caused relatively severe cybersickness. In contrast, active playing of the game led to diminishing cybersickness, according to a study published in the journal Cyberpsychology, Behavior, and Social Networking.

Virtual reality sickness, or cybersickness, is a significant obstacle to being able to sustain the feeling of presence in the virtual reality experience.

Upyong Hong, Ph.D., from Konkuk University, and coauthors, investigated whether the degree of cybersickness varies depending on how the virtual reality content is experienced, and whether specific eye movement characteristics are associated with changes in cybersickness. The investigators collected and analyzed eye-tracking data.

Eye movement patterns changed depending on the different levels of cybersickness. Eye movements became more restricted as cybersickness increased. The investigators concluded that “more active eye movements reduced cybersickness. Thus, the restricted eye movements in the passive watching mode can be considered the cause of the higher level of cybersickness.”
