ABSTRACT

Location-based systems (LBS) can be of benefit to obtain information when and where it is needed. What is not captured with LBS are points of interest (dynamic hotspots) that are not fixed in one location, such as people. Furthermore, using 2D interface elements makes it difficult to communicate precise spatial information to users. The current study aims to assess the viability of dynamic hotspots and augmented content in a mobile hotspot policing application. Mock cases were constructed to mimic real field policing work. The system, comprised of a smartphone and smartwatch, gave static and dynamic hotspot information, which was enriched with the use of augmented elements viewed through the smartphone-camera. Interviews, observations and usability measures were used to gain insight for augmented reality (AR) design considerations in the domain of field-policing. The detection of dynamic hotspots was seen as desirable. While static and dynamic hotspot information was seen as valuable, AR information, as it was utilized in the current study, has too many drawbacks to be used in the field. Alternative modalities, insights into possible future iterations and technical limitations of AR for the emergency response domain are discussed.

摘要

基于位置的系统（LBS）可以在需要的时间和地点获得信息。LBS未捕获的是未固定在一个位置（例如人）中的兴趣点（动态热点）。此外，使用2D界面元素使得难以将精确的空间信息传达给用户。当前的研究旨在评估移动热点策​​略应用中动态热点和增强内容的可行性。模拟案例的构建是为了模仿实际的现场警务工作。该系统由智能手机和智能手表组成，可提供静态和动态热点信息，并通过使用通过智能手机相机查看的增强元素来丰富该信息。面试 观察和可用性度量用于了解现场警务领域中的增强现实（AR）设计注意事项。动态热点的检测被认为是可取的。虽然静态和动态热点信息被认为是有价值的，但是如本研究中所使用的，AR信息具有太多的缺点，无法在该领域中使用。讨论了替代模式，对未来可能的迭代的见解以及AR在紧急响应领域的技术局限性。
