Does Size Matter? Exploring how Standard and Large-Scale Displays affect Off-site Experts during AR-Remote Collaboration

Abstract

Most efforts on Augmented Reality (AR) remote collaboration have been devoted to on-site individuals in need of assistance. Yet, since remote experts do not have access to the local environment, it is also important to explore how different methods affect the situation understanding and interaction. This work describes a user study with 16 participants aimed at comparing how remote individuals interact with standard (C1) and large-scale displays (C2) while providing assistance during a remote maintenance scenario. Results suggest condition C2 was preferred by the majority of participants, being considered more useful to analyze important details of the task context, as well as more easily create content.
