Abstract: 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.

摘要: 增强现实通过将数字内容叠加到物理世界,为用户提供沉浸式的数字体验,帮助用户更好地理解真实世界。近年来增强现实上下文感知研究受到广泛关注。增强现实与其上下文密切相关,无论是位置信息、光照水平、头部姿态等基础的上下文信息,还是几何信息、语义信息、眼动信息等更高等级的上下文信息,都不同程度影响增强现实的用户体验。从增强现实上下文感知的最新研究进展出发,概括了增强现实的上下文因素,梳理了增强现实上下文感知的流程,并对增强现实中几何、语义和眼动三种上下文信息的感知方法与最新应用进行了分析。最后,结合增强现实上下文感知研究的现状,探讨了增强现实上下文感知的未来发展趋势,为后续的增强现实上下文感知研究提供参考。
