The effect of additional shooting task on alleviating virtual reality motion sickness

Virtual reality motion sickness (VRMS) is a key obstacle in user experience and development of virtual reality technology. Given the existed condition of technology, the adjusts on the virtual reality scene and content is convenient and low-cost way to reduce the influence of VRMS. This paper aims to investigate whether the additional task in a virtual reality content can reduce the VRMS level. We collect the EEG data and simulator sickness questionnaire from the subjects during their riding a virtual reality roll coaster with and without an additional shooting task. In final, the statistic method is used to analyze the rhythm energies and differential entropies of the EEG. The SSQ results show that the shooting task can reduce the VRMS severity. The difference of the EEG features between the shooting task and no-task is also more significant than those between different field of view, that is a further proof of the reduction effect of the additional shooting task on VRMS. This study reveals the effect of additional shooting task on the VRMS and provides a novel beginning point of research on the use of additional task to prevent VRMS.
