  Trust has emerged as a key factor in people's interactions with AI-infused
systems. Yet, little is known about what models of trust have been used and for
what systems: robots, virtual characters, smart vehicles, decision aids, or
others. Moreover, there is yet no known standard approach to measuring trust in
AI. This scoping review maps out the state of affairs on trust in human-AI
interaction (HAII) from the perspectives of models, measures, and methods.
Findings suggest that trust is an important and multi-faceted topic of study
within HAII contexts. However, most work is under-theorized and under-reported,
generally not using established trust models and missing details about methods,
especially Wizard of Oz. We offer several targets for systematic review work as
well as a research agenda for combining the strengths and addressing the
weaknesses of the current literature.
