Prof. Zeller presents a range of projects in HRI that challenge our traditional concepts of how we should design Human-Robot Interaction research and design. To be able to integrate different dimensions and disciplines, she introduces an extended HRI design and evaluation framework that includes facts, figures but also "softer" social concepts and relevant paradigms.

Perception is a complex process that brings observers to interpret sensory inputs based on their own previous experiences, predictions, and intentions. Even social interaction shapes this process because others are incorporated when they implicitly provide relevant information to the observer. As a result, interaction is supported by jointly perceiving the environment with others, a capability called Shared Perception. If Shared Perception is essential among humans, it is also pivotal to interact with robots. Walking along two of the principal axes of HRI research, the study of humans while interacting with robots and the development of robots to make them interact with humans, this talk will present why, in HRI, it is crucial to think beyond the mere content of perception. Therefore, the first part of the presentation will consist of a theoretical introduction to the concept of Shared Perception. In the second part, I will exhibit some experimental results collected from HRI user studies to show that human perception is a function of previous experience and social interaction. Eventually, I will address the implementation of robotic perceptual abilities to support verbal communication (reception of verbal content) through human non-verbal cues.

We live in a world where we interact with security artefacts everyday, even if we don’t notice it. Every single time we visit a website our browsers are encrypting content on our behalf to keep our communications secure and providing cookies that not only enable staying logged in to the websites but also being tracked on the web. In this talk I will briefly go over research I have been involved with in designing and analysing such artefacts and understanding people’s interactions with them. I will give a few examples of recent work in web tracking, password managers, and WhatsApp ‘security code’ verification and discuss lessons learnt.

Interest in the adoption of robot-based support for older adults is growing, even if so far it has received limited adoption in current assistance practices. Humanoid robots can interact through various modalities, which can be useful for creating social and emotional interaction, thus increasing their acceptability and user engagement. Since older adults are a category of users very varied in terms of their preferences, interests, and abilities, it can be useful to propose serious games for cognitive training that are able to personalise exploiting facts and memories from their life, and thus be more relevant for each of them. I will present the approach to personalised serious games for cognitive training with humanoid robots, developed in our group in the CNR SERENI project, and the platform prototype we designed and developed to support them. The discussion will also consider the recent experience carried out in a trial with a group of mild cognitive impairment older adults.

Despite early successes, building self-driving vehicles is clearly a massive long-term challenge. In this talk I will describe our work studying the testing of self driving cars on public roads, in particular, the Tesla ‘FSD beta’, and the Waymo driverless taxi service. We study video recordings of self-driving cars being driven in different cities, looking specifically at how they manage their interactions with other drivers. While the cars featured in these videos can (mostly) navigate the physical environment of the road, it is clear that they still face multiple challenges in communicating with other drivers. The road is a surprisingly social space, and this creates major challenges for self-driving cars to both communicate their actions to others, but also to see how others communicate to them. In particular, self-driving cars often halt suddenly on the road. While these behaviours do not break any traffic rules (and in many cases is the safe thing to do) they break the sequential and temporal expectations of road interaction. Building on this work I will discuss the broader problem of ‘designing robotic motion’ and how interaction researchers and robot designers can work together on some recent challenges in human robot interaction. This work draws on two of my recent papers published at ACM CHI - https://dl.acm.org/doi/abs/10.1145/3544548.3581045 and the ACM group conference - https://dl.acm.org/doi/10.1145/3567555

When humans talk to each other face-to-face, they use their voices, faces, and bodies together in a rich, multimodal, continuous, interactive process. For a robot to participate fully in this sort of natural, face-to-face conversation in the real world, it must also be able not only to understand the social signals of its human partners, but also to produce appropriate signals in response. I will present recent research in this area, and will also discuss the emerging ethical implications of real-world deployment of socially intelligent robots.

Attestation is one of the most critical mechanisms in confidential computing (CC). This talk presents a novel approach based on the combination of Trusted Execution Environment (TEE)-agnostic attestation architecture and formal analysis enabling comprehensive and rigorous security analysis of attestation mechanisms in CC. We demonstrate the application of our approach for three prominent industrial representatives, namely Arm Confidential Compute Architecture (CCA) in architecture lead solutions, Intel Trust Domain Extensions (TDX) in vendor solutions, and Secure CONtainer Environment (SCONE) in frameworks. For each of these solutions, we provide a comprehensive specification of all phases of the attestation mechanism in confidential computing, namely provisioning, initialization, and attestation protocol. Our approach reveals design and security issues in Intel TDX and SCONE attestation.

Many countries around the world are faced with challenges relating to an increasingly aging population and growing shortage of caregivers to support them. Robots, along with other technology solutions, hold significant promise to fill this gap. However, it has not yet been fully considered how these capabilities could be integrated into the daily lives of professional caregivers and care recipients. In this talk, I will present a research program that seeks to uncover the needs of these two key user groups to understand how assistive robots can be successfully integrated into senior living communities. First, we worked with professional caregivers using ethnographic and co-design methods to identify their workflows and needs from robotic assistance. Second, we developed a novel method called Situated Participatory Design to work with residents of a senior living community to explore how a robot could fit into their day-to-day lives. I will present results from both of these field studies and discuss the complex set of factors that influence how assistive robots need to be personalized to succeed in the complex caregiving ecosystem.
