Remote Asynchronous Collaboration in Maintenance scenarios using Augmented Reality and Annotations

This paper presents an Augmented Reality (AR) remote collaborative approach making use of different stabilized annotation features, part of an ongoing research with partners from the industry. It enables a remote expert to assist an on-site technician during asynchronous maintenance tasks. To foster the creation of a shared understanding, the on-site technician uses mobile AR, allowing the identification of issues, while the remote expert uses a computer to share annotations and provide spatial information about objects, events and areas of interest. The results of a pilot user study to evaluate asynchronous collaborative aspects while using the approach are also presented.
