The use of Augmented Reality (AR) has the potential to make everyday experiences exciting and educational. For example, AR can augment exhibits in museums with animated and interactive content. The creation of this content, however, is still facing challenges. To meet these, we employ reusable, pattern-based building blocks called AR nuggets. An AR nugget implements one application pattern in a small and self-contained piece of software to provide a complete solution for recurrent AR-based experiences. For example, in the application context of museums and exhibitions, we identify superimposition or visualization of echolocation as general patterns for AR use cases. AR nuggets encapsulate AR-specific knowledge and sophisticated functionalities to support authors and reduce the authoring task to tweaking existing templates to individual exhibits. To connect AR nuggets used in different exhibition rooms, we present novel AR nuggets that encapsulate the functionalities needed for creating a path between the exhibits. Additionally, we provide examples of AR nuggets that implement a virtual character that guides visitors to exhibits of interest. With this new set of AR nuggets, spatial connections can be authored, e.g., in the form of a guided tour with interactive narration. For this authoring task, we introduce an AR nugget manager that supports authors in creating and adapting multiple non-linear AR experiences. We illustrate our approach with the creation of an everyday AR application for a museum of natural history, share our experiences and discuss to what extent our approach can mitigate authoring challenges for everyday AR applications from a museum’s point of view. This work contributes to the field of everyday AR with 1) a pattern-based authoring concept to create complex everyday AR experiences based on self-contained building blocks, 2) a set of patterns that allows for spatial connections of these to create non-linear AR content, 3) means for supporting this authoring process in the form of an AR nugget manager, 4) lessons learned in applying our authoring concept in a real application case in a museum, 5) our observation of hurdles that still prevent more widespread use of AR in everyday applications during the realization of this application case.

“…Authors can design interactions between visitors and avatars using placement, traversal, and formation rules (Singh et al. 2021 ). In addition, the author can create new narrative spaces with prequels, sequels, and spin-off secondary characters by expanding the time, place, and characters of the TV show’s narrative space (Pratten 2011 ).…”

Spatial transition management for improving outdoor cinematic augmented reality experience of the TV show

et al. 2022

There have been attempts to provide new cinematic experiences by connecting TV or movie content to suitable locations through augmented reality (AR). However, few studies have suggested a method to manage breakdowns in continuity due to spatial transitions. Thus, we propose a method to manage the spatial transition that occurs when we create a TV show trajectory by mapping TV show scenes with spatiotemporal information to the real world. Our approach involved two steps. The first step is to reduce the spatial transition considering the sequence, location, and importance of TV show scenes when creating the TV show trajectory in the authoring tool. The second is to fill the spatial transition with additional TV show scenes considering sequence, importance, and user interest when providing the TV show trajectory in the mobile application. The user study results showed that reducing spatial transition increases narrative engagement by allowing participants to see important content within the trajectory. The additional content in spatial transition decreased the physical demand and effort in terms of the perceived workload, although it increased the task completion time. Integrated spatial transition management improved the overall cinematic augmented reality (CAR) experience of the TV show. Furthermore, we suggest design implications for realizing the CAR of TV shows based on our findings.
