Abstract
Head-mounted displays and physically separated team tasks – effects of a shared visual context on performance Introduction: Teams are required to be physically separated to work in certain circumstances. Tasks like troubleshooting in industrial maintenance include the manipulation of objects and the interpretation of information from the work environment. It is harder for physically separated team members to do these jobs if they communicate exclusively via an audio connection. Technologies such as head-mounted displays can provide a shared visual context by enabling a look over the shoulder of a team member working in another location. Aim: The present study examined the impact of a shared visual context on performance in physically separated troubleshooting. Methods: An experimental study provided for 36 teams (72 subjects), each consisting of two test subjects who were in different rooms, to work on a synthetic fault diagnosis task that had been prepared beforehand. Results: Teams with a shared visual context resolved significantly more faults than teams without a shared visual context. Conclusion: In practice, the use of head-mounted displays must be given careful consideration since they are worn on the user’s body and may be perceived as restrictive or uncomfortable in certain circumstances. Keywords: teams – physically separated team tasks – head-mounted displays – shared visual context
