Getting the Most out of Virtual Reality: Evaluating Short Breaks to Reduce Cybersickness and Cognitive Aftereffects

Considering the importance of getting the most out of virtual reality (VR) training, we evaluated the use of breaks to reduce virtual reality aftereffects in head-mounted displays. In a crossover design, we compared a 50-minute no-break exposure with an interrupted 50-minute exposure with four 10-minute breaks. Cybersickness, re-action times, workload and spatial learning were measured. Despite device manufacturers recommending breaks to reduce sickness, we found no evidence that breaks can mitigate aftereffects. Introducing breaks may also impact performance and logistical costs for training.
