CroMAR: Mobile Augmented Reality for Supporting Reflection on Crowd Management

This paper discusses the usage of Mobile Augmented Reality MAR to support reflection on past events, using reflection on crowd management as scenario. Computer based support to reflection generally relies on the visualization of information connected to the experience one is reflecting upon. Different metaphors have been adopted to support easy access to relevant information within the reflection process, e.g., timelines and word clouds. In this context, MAR represents an interesting alternative because it can be used to promote reflection in the specific location of the event by augmenting it with relevant information. In this way, the authors can expect the reflection process to be grounded in a context that helps to make sense of the information and reflect on alternative paths of action. The paper presents the scenario of usage, together with the design, development, and evaluation of the prototype, CroMAR. Based on this experience, the authors identify challenges connected to the usage of Mobile Augmented Reality in terms of support for reflection, interaction, and design methodology.
