摘　　要：增强现实技术被广泛应用于增强现实系统,但该系统是否有助于降低用户认知负荷、提升用户作业效率和使用体验目前还存在一定争议。选取5个国内外权威数据库,检索筛选出25篇相关实证研究文献,共计31组数据进行元分析,对不同增强现实设备以及使用时间进行调节效应分析。从整体上看,增强现实系统有助于降低认知负荷;从设备类型来看,使用非可穿戴式设备时认知负荷的降低效果更好;从系统功能来看,学习系统和信息提示系统都能降低认知负荷。当使用增强现实信息提示系统时,使用超过30min反而会增加认知负荷。在未来的设计中,需要依据用户特征和任务类型找准AR技术的介入路径,提升系统的可用性,同时促进多学科融合发展,提升AR技术与人机系统的适配性。Augmented reality technology is widely used in augmented reality systems.Whether augmented reality systems help reduce user cognitive load and improve completion efficiency and user experience are still controversial.Therefore,five domestic and international authoritative databases were selected,and a total of 31 sets of data from 25 relevant empirical studies were retrieved and screened for meta-analysis to analyze the moderating effects of different augmented reality devices,system types,and using time.On the whole,augmented reality systems contribute to cognitive load reduction.In terms of device type,cognitive load reduction is better when using non-wearable devices.In terms of system type,both learning systems and informational systems can reduce cognitive load.When using augmented reality information prompting systems,more than 30 minutes will increase cognitive load.In the future design,it is necessary to find the intervention path of AR technology according to user characteristics and task types,so as to improve the system usability.Besides,it’s also necessary to promote the integration and development of multiple disciplines and improve the adaptability of AR system.
