To facilitate quality interdisciplinary reviewing, and to inform reviewer selection, authors will be required to select one main theme and one optional second theme for their full paper submissions.

The HRI 2021 conference has four themes: User Studies, Technical Advances, Design, and Theory and Methods. Papers may have overlap between themes, but authors are encouraged to consider the main contribution of the work using this brief rule of thumb:

HUMAN-ROBOT INTERACTION USER STUDIES

The primary contribution is knowledge gained from human-focused experiments, e.g., new understandings of how humans perceive, interact with, or otherwise engage with robots.

TECHNICAL ADVANCES IN HUMAN-ROBOT INTERACTION

The primary contribution is system-focused, e.g., algorithms, or computational methods supporting HRI.

HUMAN-ROBOT INTERACTION DESIGN

The primary contribution is design-focused, e.g., new morphologies, behavior paradigms, or interaction capabilities for robots.

THEORY AND METHODS IN HUMAN-ROBOT INTERACTION

The primary contribution is methodological, e.g., new ways of studying HRI, elucidating or connecting fundamental HRI principles beyond individual interfaces or projects, new theoretical concepts in HRI, literature reviews, work that reproduces, replicates, or re-creates prior HRI work (or fails to), provides new HRI artifacts (e.g., datasets, software), etc.
