There are many challenges when it comes to deploying robots remotely including lack of operator situation awareness and decreased trust. Here, we present a conversational agent embodied in a Furhat robot that can help with the deployment of such remote robots by facilitating teaming with varying levels of operator control.

Curry, Amanda Cercas, Hastie, Helen, Rieser, Verena.  2017.  A Review of Evaluation Techniques for Social Dialogue Systems. Proceedings of the 1st ACM SIGCHI International Workshop on Investigating Social Interactions with Artificial Agents. :25–26.

In contrast with goal-oriented dialogue, social dialogue has no clear measure of task success. Consequently, evaluation of these systems is notoriously hard. In this paper, we review current evaluation methods, focusing on automatic metrics. We conclude that turn-based metrics often ignore the context and do not account for the fact that several replies are valid, while end-of-dialogue rewards are mainly hand-crafted. Both lack grounding in human perceptions.
