For automated driving?"" <LINK> One main takeaway: Focus modelling on those aspects of human behaviour to which interaction outcome (safety, performance, satisfaction) is most sensitive - but finding out which those aspects are is a research question in its own right - needs addressing also for ML models To be presented next week at the ACM/IEEE HRI 2022 Workshop on Modeling Human Behavior in Human-Robot Interactions Really stoked about this workshop overall - come listen if you can! <LINK> @arashttavakoli Oh glad you liked it! 👍",https://arxiv.org/abs/2202.06123,"There are many examples of cases where access to improved models of human behavior and cognition has allowed creation of robots which can better interact with humans, and not least in road vehicle automation this is a rapidly growing area of research. Human-robot interaction (HRI) therefore provides an important applied setting for human behavior modeling - but given the vast complexity of human behavior, how complete and accurate do these models need to be? Here, we outline some possible ways of thinking about this problem, starting from the suggestion that modelers need to keep the right end goal in sight: A successful human-robot interaction, in terms of safety, performance, and human satisfaction. Efforts toward model completeness and accuracy should be focused on those aspects of human behavior to which interaction success is most sensitive. We emphasise that identifying which those aspects are is a difficult scientific objective in its own right, distinct for each given HRI context. We propose and exemplify an approach to formulating a priori hypotheses on this matter, in cases where robots are to be involved in interactions which currently take place between humans, such as in automated driving. Our perspective also highlights some possible risks of overreliance on machine-learned models of human behavior in HRI, and how to mitigate against those risks.
