Reflections on a Comparative AR Study

A variety of studies exist that design innovative interactions based on augmented reality (AR). Comparing them often involves examining their laboratory studies. However, since AR has a high context dependency (e.g., reference to the real environment), it is important to emphasize that existing literature do not reveal generalizable results regarding how to design AR instructions. Within this paper, we argue that it is time to open up new use cases and test appropriation mechanisms in practice with the help of long-term studies to build a base for the comparison of AR-based interactions. Such a repository built up with long-term studies has the potential to define valid insights for future developments in the AR environment.
