Motion sickness caused by prolonged augmented reality/virtual reality (AR/VR) displays is a short-term dysfunction triggered by allostatic stimuli. In particular, when the resolution and image response rate of AR devices are insufficient, severe motion sickness is one of the key factors affecting user experience. This paper first explains the pathogenesis and performance of motion sickness, analyzing the disorders caused by image stimulation and motion sickness. Second, the composition and classification of AR equipment are summarized, and the sources and management modes of delays are introduced. Subsequently, solutions are discussed to improve motion sickness and optimize the user experience from various technical perspectives. Finally, future development avenues for AR/VR display systems are presented.
