Exploiting physiological data to detect virtual reality sickness

Researchers at IRT b-com, France, explored the use of physiological signals from noninvasive wearable devices like the E4 to detect virtual reality sickness. Their method involved training Machine Learning models using data from the E4 to detect when participants felt sick while playing video games for 30 minutes, in addition to self-reporting. Results from the study showed up to 91% accuracy in detecting VR sickness when using the E4, paving the way for adapting VR video games to players’ sickness levels using real-time feedback.
