Reducing cybersickness by implementing texture blur in the virtual reality content

Virtual reality facilities have matured in recent years; however, cybersickness has yet remained a major issue in the virtual reality content. The researchers in this study attempt to simulate the different focal points and depth of field of human vision with an eye on reducing cybersickness by implementing blurring. This paper introduces a new type of technology—texture blur, which was tested in three experiments with different contents in this study. The participants were asked to verbally answer two questionnaires: a discomfort level questionnaire and a simulator sickness questionnaire (SSQ). The results were analyzed to compare the seriousness of the participants’ cybersickness with and without texture blur in the virtual reality content. The experiment results revealed that the participants with texture blur had lower discomfort level scores. The SSQ results also went in line with the previous questionnaire, showing better results with texture blur. Hence, the researchers concluded that texture blur can effectively reduce users’ cybersickness in virtual reality content.
