Abstract
Remote assistance involves two individuals, an onsite technician and an off-site expert, with different knowledge and physical access to the task object. This study examines the use of Mixed Reality (MR) head-mounted displays for 3D remote assistance tasks, exploring performance as well as the collaboration dynamics from the point of view of both technicians and experts. A laboratory experiment with technician-expert dyads was used in which teams performed 3D remote assistance tasks using MR and videoconferencing (VC, control condition). Preliminary analyses showed that MR significantly outperformed VC in task performance for both low and high complexity tasks. When using MR, teams reported higher ease of use and higher engagement. However, no relationship was found between either ease of use or engagement and performance. The next phase of analysis will examine the experiment recordings to inductively code specific technician and expert behaviors to explore collaboration dynamics.
