This systematic literature review investigates cybersickness (CS) in virtual reality (VR), a condition that can cause symptoms like nausea, dizziness, and eye strain when users interact with VR technology. The review analyzes 223 studies to explore the causes, measurement techniques, and mitigation strategies for CS. It proposes a novel taxonomy for CS measurement and provides guidelines for both developers and users to reduce CS. The review also identifies key factors contributing to CS, including age, gender, motion sickness susceptibility, physical conditions, and emotional states. External factors such as hardware, VR content, and user interaction methods also play a significant role in CS. The review highlights the importance of measuring CS through various techniques, including questionnaires, physiological signals, and behavioral data. It emphasizes the need for further research to address gaps in understanding CS and to develop effective mitigation strategies. The review concludes that a comprehensive understanding of CS is essential for improving VR experiences and reducing user discomfort.This systematic literature review investigates cybersickness (CS) in virtual reality (VR), a condition that can cause symptoms like nausea, dizziness, and eye strain when users interact with VR technology.
