Design and Evaluation of a Distance-Driven User Interface for Asynchronous Collaborative Exhibit Browsing in an Augmented Reality Museum

https://ieeexplore.ieee.org/document/9431194


Augmented reality museums allow visitors to jointly view and interact with exhibits. However, real-time exhibit browsing does not accommodate latecomers to museums and offers limited support to temporally separated visitors. To stimulate asynchronous exhibit browsing, we developed a distance-driven user interface that divided the augmented reality exhibit-egocentric space into four distance ranges, each having a set of social networking features and different privileges for exhibit viewing and interaction. The user interface enables asynchronous exhibit browsing for visitors participating at different times. We conducted empirical studies to evaluate how the user interface affected visitors’ collaborative exhibit browsing in terms of perceived usability and learning gains. The results show that the perceived usability of the user interface is consistently high across all distance ranges. The user interface stimulates collaborative exhibit browsing with significant improvements in learning efficiency and learning attention durations, although learning satisfaction showed no difference across the participants. Implications for how the distance-driven user interface can be generalized for other interactive applications are discussed.


1. Background : 증강현실 박물관을 통해 사람들이 interactive 한 체험을 할 수 있다. 

Augmented reality museums allow visitors to jointly view and interact with exhibits. 

2. Problem : 실시간 전시 브라우징은 늦게 들어온 사람, 일시적으로 무리를 이탈한 방문객을 수용하지 못한다. 

3. Solution : 거리를 기준으로 작동하는(distance-driven user interface) 인터페이스를 사용해 비동기화된 전시 브라우징을 개발하였다. 

4. Result : 콘텐츠를 모든 거리 범위에서 일관되게 관찰할 수 있다. 

5. Contribution : 다른 interactive application 에도 distance-driven user interface를 적용할 수 있다.

Even though large displays provide more display space, they are challenging with regard to perception, effective multi-user support, and managing data density and complexity. To address these issues and illustrate our proposed setup, we contribute an extensive design space comprising first, the spatial alignment of display, visualizations, and objects in AR space. Next, w...
