<div dir="ltr">The theme of this year for HRI’21 is “Bolder HRI”. Consequently, Alt.HRI aims to be even bolder, i.e. “Bolder Square.” Alt.HRI track is looking for the most audacious, creative and thought-provoking ideas supported by rigorous research that does not fit elsewhere. We aim to reach our colleagues from disciplines that aren't part of the mainstream of HRI yet and ask for the unexpected, the controversial, the creative, and the diverse. Alt.HRI 2021 aims to be unexpected, resilient, and bold according to the 2020ies zeitgeist. Alt.HRI studies can be described as radical, unique, provocative, inspiring, controversial, nonobvious, rare, unusual, and also relevant, rigorous, well-argued, and research-supported. Topics such as HRI and Art, aestheticism in robotics, critical HRI, speculative HRI, historical studies related to HRI, new methods in HRI, controversial methods in HRI, learning from small samples, robots and gender, sexism in robotics, feminism and robotics, robots and COVID, HRI in the lockdown, robots and racism, social justice, robot rights, robot ethics, robot laws, robot behaviours, robot and politics, robots and religion, against pseudoscience in HRI, fun studies in HRI, novel robot designs and implementations are possible in Alt.HRI. Of course, other controversial topics and approaches are also welcome. Alt.HRI papers aim to trigger meaningful and respectful discussions in the HRI community.
