Augmented reality provides users with immersive digital experiences by overlaying digital content on top of physical world and helps users better understand reality. In recent years, research on context awareness in augmented reality has received widespread attention. Augmented reality is closely related to its usage context, not only it is basic contextual information such as location information, light level, head posture, but also higher level contextual information such as geometric information, semantic information and eye movement information, these contextual information have impacts on user experience of augmented reality in various degrees. Based on recent advances in context awareness of augmented reality, this paper outlines the contextual factors of augmented reality, illustrates the context-aware processing flow in augmented reality, and analyzes the context-aware algorithms and latest applications related to geometry, semantics and eye movement contextual information in augmented reality. Finally, combined with the current status of augmented reality contextual awareness, it discusses the future development trends of augmented reality contextual awareness, so as to provide reference for future research.
