In this paper, we report on the evaluation of a remote assistance platform (RAP) that is designed to enable an expert to remotely assist a field operator. A user study with 16 participants was conducted to evaluate its
usability with two assembly tasks that varied in their complexity. As part of the assessment, we compared
the interaction behavior of our platform with a commercial instant messaging application, which lacked
the ability to augment or view video imagery. The results identified differences in the completion times
between the two conditions, as we examined the use of visual augmentation, including recommendations to
improve the platform.
