论文摘要
增强现实（AR）弥合了物理世界和虚拟世界之间的差距。通过覆盖自然环境上的图形，用户可以将自己沉浸在量身定制的环境中。这为移动旅游业带来了巨大的好处，其中兴趣点（POI）可以在智能手机屏幕上注释。尽管目前存在各种应用程序，但可用性问题可能会阻止用户拥抱AR。界面可能会被图标混乱，POI遮挡带来了进一步的挑战。在本文中，我们使用以用户为中心的设计（UCD）开发AR旅游应用程序。我们通过综合域分析，旅游观察和半结构化访谈来征求要求。尽管以前以用户为中心的工作设计了模型，但我们迭代地开发了一个完整的Android应用程序。除了详细的AR浏览器外，这还包括开销图和路线导航。最终产品由20个用户评估，他们参加了在英国城市的旅游任务。用户将该系统视为可用和直观的，并建议添加进一步的自定义。我们通过严格分析以用户为中心的方法的挑战来结束。
Augmented Reality (AR) bridges the gap between the physical and virtual world. Through overlaying graphics on natural environments, users can immerse themselves in a tailored environment. This offers great benefits to mobile tourism, where points of interest (POIs) can be annotated on a smartphone screen. While a variety of apps currently exist, usability issues can discourage users from embracing AR. Interfaces can become cluttered with icons, with POI occlusion posing further challenges. In this paper, we use user-centred design (UCD) to develop an AR tourism app. We solicit requirements through a synthesis of domain analysis, tourist observation and semi-structured interviews. Whereas previous user-centred work has designed mock-ups, we iteratively develop a full Android app. This includes overhead maps and route navigation, in addition to a detailed AR browser. The final product is evaluated by 20 users, who participate in a tourism task in a UK city. Users regard the system as usable and intuitive, and suggest the addition of further customisation. We finish by critically analysing the challenges of a user-centred methodology.
