Dear colleagues,

Apologies for any cross-posting

It is our great pleasure to invite you to submit your work at the second edition of TRAITS - The Road to a successful HRI: AI, Trust and ethicS Workshop that will be held in conjunction with HRI 2022 conference.

The workshop and conference will be fully online on March 7-11, 2022. This year edition of TRAITS will have the participation of three amazing keynote speakers that will share their valuable experience and knowledge covering topics on AI, trust and ethics in HRI.

More information can be also found on the website and social media: Workshop Website: https://sites.google.com/view/traits-hri-2022/home Workshop Twitter account: @HriTraits

For any questions and further information, please do not hesitate to email me.

Kind regards, Alessandra On behalf of the organising committee

TRAITS 2022: The Road to a successful HRI: AI, Trust and ethicS online March 7-11, 2022 Conference website https://sites.google.com/view/traits-hri-2022/home Submission link https://easychair.org/conferences/?conf=traits2022 Submission deadline February 21, 2022 The Road to a successful HRI: AI, Trust and ethicS - TRAITS The increasing presence of robots in human-centred environments requires natural robot behaviours to ensure a successful and efficient human-robot interaction (HRI). Guaranteeing such high quality HRIs is very challenging due to the inherent uncertainty of human-robot dynamics involving the perception, reasoning and decision-making of robots and people. In such realities, robots and people need to be able to cooperate together to reach a goal, which can only be achieved if people accept and trust robots to complete their task and prevent any potential harm (emotional or physical) to people and their belongings. Then, they need to correctly interpret the other's behaviour, and act accordingly. Finally, they need to be able to adapt and communicate their intention and internal state in a way that the other counterpart can understand and accept, e.g. through social cues. Successful HRIs, therefore, can be guaranteed by designing robots: 1) able to autonomously sense and react to the situation, people and the environment by integrating artificial intelligence (AI) techniques; 2) such that people feel comfortable to interact with robots and trust them to reach intended outcomes, and 3) by adhering to ethical and legal principles. This workshop is a continuation of a successful workshop at the HRI conference 2021. This iteration of workshop will continue contributing to the exploration of successful HRIs from a multidisciplinary perspective, and the analysis of  the different aspects of HRI that impact its success. For this reason, in this second edition, we wish to particularly focus on the AI algorithms required to implement autonomous and proactive interactions as well as to AI techniques that can make the robot explain itself and its behaviour being legible and understandable by humans. Furthermore, we concentrate  on the factors that enhance, undermine, or recover humans' trust in robots. Finally, potential ethical and legal concerns, and how they can be addressed will be considered. Submission Guidelines All papers must be original and not simultaneously submitted to another journal or conference. Authors are invited to submit an extended abstract of 2 pages or full papers up to 6 pages on original and unpublished research. We also invite authors to submit 2 pages position papers. All submitted papers will be reviewed by two reviewers. The abstracts of the accepted papers will appear on the workshop website. Authors should submit their papers formatted according to the ACM SIG format, which is also used for contributions to the main conference. All papers must be submitted in PDF format. Use the following templates to create the paper and generate or export a PDF file: LaTeX, on Overleaf or MS-Word. Following HRI 2021 directives, we invite authors to prepare an anonymised submission. Authors are expected to remove author and institutional identities from the cover page, the acknowledgements section, and the PDF meta-data. More information about how to anonymise your submission can be found on the conference website. Authors will be able to submit a PDF copy through Easychair. Please see submission instructions. List of Topics We intend to open the workshop to a broad audience from academia and industry researching social robotics, machine learning, robot behavioural control, and so on. We will foster the exchange of insights on past and ongoing research and contribute to the discussion of innovative ideas for tackling unresolved issues providing new and inspirational directions of research. Topics of interest include but are not limited to:

• Evaluation of human-robot interaction quality; • Human factors affecting successful HRI; • Mental models in HRI; • XAI in HRI; • Trustworthy AI; • Antecedents of Trust and Human-Robot Trust; • The impact of social robots on acceptance in HRI; • Legal frameworks for trustworthy robotics; • Ethics implications in HRI

Invited Speakers

• AI in HRI: Tony Belpaeme (confirmed) • Trust and acceptance in HRI: Kristin Schaefer (to be confirmed) • Ethics in HRI: John Danaher (confirmed)

Each session of the program will be interspersed with break-out sessions during which attendees will be available to networking and discuss further the workshop topics. One of the break-out sessions will be dedicated to a “mentor and mentees” event where attendees, in particular students and PhD students who just started to work in research, are encouraged to ask questions and advices to the keynotes speakers. Participants and attendees will be invited to submit questions before the workshop to allow the keynotes to also reply offline. Questions and comments will be available in a special session on the workshop website.
