Abstract Recent advances in augmented reality (AR) have attracted much attention in nutrition and healthcare education. In the context of obtaining dietary knowledge, a mobile AR system was developed for learning and exploration, which allowed students to scan food images, receive information about nutrient content and record as well as accumulate daily nutrient intake. Students could also access learning materials provided in the system to achieve the learning objectives. Their learning outcomes were gathered at the close, with reactions to the learning experiences also assessed via a set of questionnaire items (using a 5 point Likert scale) in various criteria. Both qualitative and quantitative data were gathered, showing that most students achieved the learning objectives and were positive about exploring with AR. The results of this study indicated that students with high levels of monitoring had better learning outcomes (p<0.05) and were more positive about the varied criteria in their responses, including: visual interest and learning enjoyment, functional use, personal relevance and learning of knowledge (p<0.05). The effect of the self-participatory aspect of AR on learning is emphasized.

增强现实技术在饮食监测中的应用

摘要增强现实（AR）的最新进展已在营养和医疗保健教育中引起了广泛关注。在获取饮食知识的背景下，开发了一个用于学习和探索的移动AR系统，该系统允许学生扫描食物图像，接收有关养分含量的信息并记录并累积每日养分摄入量。学生还可以访问系统中提供的学习材料以实现学习目标。他们的学习成果在结束时收集，对学习经历的反应也通过一系列不同标准的问卷调查项目（使用5点李克特量表）进行评估。收集了定性和定量数据，表明大多数学生达到了学习目标，并对使用AR进行探索持积极态度。这项研究的结果表明，具有较高监控水平的学生具有更好的学习成果（p <0.05），并且对各种标准的反应也更加积极，这些标准包括：视觉兴趣和学习乐趣，功能使用，个人相关性以及对学习的了解知识（p <0.05）。强调了AR的自我参与方面对学习的影响。
