Research on minimizing VR motion sickness in VRChat
Xiayuan Gong · 2021
In the VR social game - VRChat, VR motion sickness, as known as Cybersickness(CS), becomes a serious negative factor that degrades user experiences in VRChat. Current solutions that have been utilized to solve CS either degrade user experience in game or contain risk factors. Therefore, better CS solving methods should be applied in this field. The paper first investigates the influencing factors and inducement mechanisms of CS; analyze two classical theories - Postural instability theory and Sensory conflict theory, which explains motion sickness problems, and settle the exact inducement of CS in VRChat. Then the paper analyzes the better CS solutions according to the inadequacy of current solutions. Three promising solutions found are tricking vestibular organs, infinite space and the BCI system. After research, each of the three better solutions presented by the paper is considered to also contain disadvantages. The side effect of tricking vestibular organs requires further study; large omnidirectional treadmills are too expensive; BCI systems and EEG algorithms need improvements in accuracy. In conclusion, current solutions are not perfect and require further study in allusion to the VRChat. In the plateau of the productivity of VR technology, as technology and market size advance, there will certainly be more satisfying solutions to solve CS problems. The author also believes that peripheral devices such as VR treadmills will have better development prospects due to auxiliary features.
