Also, Thomas Edison said that 46 frames per second (FPS) eliminated flicker, but at that time, making 46 FPS film was not cheap. In 1929, in order to produce films with sound, 24 FPS was found to be the minimum frame rate to eliminate flicker. Today, in the VR industry, the frequency of camera movement is as important as the frame rate is for the film industry. The goal of this study was to find the frequency that induces the greatest intensity of motion sickness in VR users. Many articles show how frequencies induce motion sickness. In particular, Golding et al. (2007) showed that 0.2 Hz is more nauseogenic than 0.05 Hz or 0.8 Hz movement frequencies. Therefore, I hypothesize that when people experience different frequencies (0.15 Hz, 0.2 Hz, 0.25 Hz) in a stimulated Virtual reality, 0.2 Hz will induce the greatest intensity of VIMS.Method: Subjects (n=10) had their noses and ears blocked and wore VR headsets to watch a video with various movement frequencies (0.15 Hz, 0.2 Hz, 0.25 Hz) for 3 periods of 10 minutes each. Subjects responded using a Sickness Rating Scale (SRS).from 0 to 6 at 1-min intervals during the 10-min test. After the test, subjects completed a Symptoms Checklist (SC) for another 10 mins.Results: When the participants were given different frequencies (0.15 Hz, 0.2 Hz, 0.25 Hz) in a stimulated Virtual reality, 0.2 Hz (72°/s) was found to induce more VIMS.Conclusion: VR designers or developers need to know which frequencies of camera movement cause VIMS. In the study, the peak level of VIMS was found in the region of 0.2 Hz (72°/s), with higher or lower frequencies proving less powerful in generating symptoms. 2017 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1504803460291897 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1504803460291897 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
