“…Eye tracking has also been used to evaluate cybersickness, though to a lesser extent compared to other biometric measures such as ECG or EEG [8,9]. However, the increasing availability of VR HMDs with integrated eye tracking technology, coupled with its nonintrusive nature, makes eye tracking a particularly valuable tool for detecting cybersickness.…”

Extended exposure to virtual reality displays has been linked to the emergence of cybersickness, characterized by symptoms such as nausea, dizziness, fatigue, and disruptions in eye movements. The main objective of our study is to examine the effects of real-time fine-tuning of stereo parameters and blurriness in virtual reality on the discomfort level of users who are experiencing motion sickness triggered by the display. Our hypothesis proposes that by dynamically correcting the rendering settings, the symptoms of motion sickness can be relieved and the overall VR user experience can be improved. Our methodology commences with a prediction model for the comfort level of the viewer based on their gaze parameters, such as pupil diameter, blink count, gaze position, and fixation duration. We then propose a method to dynamically adapt the stereoscopic rendering parameters by considering the predicted comfort level of the viewer.
