This paper aims to present an augmented reality (AR) application to aid the elderly in library reference search. The application supports the elderly in searching books and videos in a large library when librarians have insufficient time to meet their needs. The elderly searching in a large library could be difficult for them due to the vast area, complicated online library catalogs and their physical deterioration, such as failing eyesight, tendinitis and memory problems. Our system, SearchAR, fully supports the 3D images of object content based on books and videos in Ling Tung University (LTU) library catalogs. Using the latest AR technology, users can use mobile phone to scan the quick response (QR) code in front of the LTU library, and then the elderly can experience LTU library map labeled by different colors in real-time and understand the locations of the video areas and book shelves areas. Later, they can use SearchAR to scan the QR codes on bookshelves, books or videos to view the 3D graphics without reading complicated catalogs and content. The results show that among the images, the elderly recognition of the “3 D images” was the highest, and the experimental group using AR technology as a searching aid shows a higher searching effectiveness than the control group; 60 per cent of the elderly felt they saved more time for searching books and videos with the help of SearchAR, and it was easy to arouse their association; the elderly indicated that combined image of the library map and the labels with different colors are clear and simple; the content of books and videos are easy associated with the 3D images; the elderly mentioned that using SearchAR is a great experience without any reading complicated online catalogs. Finally, this study concludes that AR technology does enhance the elderly searching ability in LTU large library.,The SearchAR application was an integrating library catalog, which provides AR and 3D graphics. The elderly can also use SearchAR to see a library map and every library element via 3D graphics before they start searching in a wide area.,This makes it easier for elderly to navigate a library without using complicated online catalogs, and it reduces time spent on reading and searching.,AR has been used for a variety of guiding and educational purposes. However, AR has been rarely applied to supplement traditional library services for elderly.

老年辅助设备替代传统在线图书馆目录

本文旨在提出一种增强现实 (AR) 应用程序，以帮助老年人进行图书馆参考文献搜索。当图书馆员没有足够的时间来满足他们的需求时，该应用程序支持老年人在大型图书馆中搜索书籍和视频。由于面积广阔、网上图书馆目录复杂以及他们的身体状况恶化，例如视力下降、肌腱炎和记忆问题，老年人在大型图书馆中搜索可能对他们来说很困难。我们的系统 SearchAR 完全支持基于岭东大学 (LTU) 图书馆目录中的书籍和视频的对象内容的 3D 图像。采用最新的AR技术，用户可以用手机扫描LTU图书馆前的快速响应（QR）码，然后老年人可以实时体验不同颜色标记的LTU图书馆地图，并了解视频区和书架区的位置。之后，他们可以使用 SearchAR 扫描书架、书籍或视频上的二维码来查看 3D 图形，而无需阅读复杂的目录和内容。结果显示，在图像中，老年人对“3D图像”的识别度最高，使用AR技术作为搜索辅助的实验组的搜索效率高于对照组；60%的老年人觉得在SearchAR的帮助下他们可以节省更多的时间来搜索书籍和视频，并且很容易引起他们的联想；老人表示，图书馆地图和不同颜色标签的组合图像清晰简洁；书籍和视频的内容很容易与 3D 图像相关联；老人提到使用 SearchAR 是一种很棒的体验，无需阅读复杂的在线目录。最后，本研究得出结论，AR 技术确实增强了老年人在 LTU 大型图书馆中的搜索能力。SearchAR 应用程序是一个集成的图书馆目录，提供 AR 和 3D 图形。老年人在开始大范围搜索之前，还可以使用 SearchAR 通过 3D 图形查看图书馆地图和每个图书馆元素。,这使老年人在不使用复杂的在线目录的情况下更容易浏览图书馆，并减少了花费在阅读上的时间阅读和搜索。AR 已被用于各种指导和教育目的。然而，AR很少被应用于补充传统的老年人图书馆服务。
