The conference will be held in-person. Although, as some authors experienced difficulties with their travelling arrangements for Ljubljana, the Program Committee decided to enable them to present their work online.


  • Fluid and Cooperative HMI for Vehicle – Pedestrian Interactions
    (Dr. Paolo Pretto, Virtual Vehicle Research Center, Graz, Austria)

In most current cars, human–machine interfaces (HMI) have limited capabilities of sensing and predicting drivers’ and pedestrians’ behavior. Therefore, it is possible that drivers are presented with information that is unsuitable for the situation, which results in low usability and increased risk of distraction. Furthermore, the exchange of information between driver and other road users is currently limited, which often results in uncertain and unsafe situations for vulnerable road users. Driving automation only exacerbates the above-mentioned problem, as drivers may be disengaged from the driving task and unaware of dangers, while pedestrian are unable to estimate the intention of vehicles. Overall, this can lead to pedestrians being exposed to (more) dangers and drivers being presented with (more) distracting warnings. Internal adaptive HMI and external HMI are an attempt to address these issues. However, research and standardization efforts are still limited.
A series of publicly-funded projects (Horizon 2020 – HADRIAN and Horizon Europe – HEIDI) aims to develop a fluid, collaborative HMI that holistically integrates internal and external adaptive HMI solutions. Initially, the features of fluid interaction systems are designed and evaluated to fulfill driver’s needs and roles in automated vehicles. Then, a fluid and collaborative HMI effectively gathers and synchronizes driver’s data and data from other road users to enable optimal joint action by all stakeholders. The coordination logic conforms to the principle of Foresight Safety®, i.e., the human-like ability to anticipate hazards and proactively avoid dangerous situations. In this way, fluid and cooperative HMI solutions guarantee that all road users have the same understanding of the situation and ensure safe interaction between vehicles and vulnerable road users. Fluid internal and external interfaces coordinate information and joint-action recommendations addressing all user categories, while adapting to their respective states and conditions like, e.g., distracted drivers and older pedestrians, to optimize efficiency, comfort and safety.

  • What’s the Matter with Vehicle Automation Ethics?
    …or: What Really Matters in Vehicle Automation Ethics

    (Dr. Alexander Mirnig, Paris Lodron University Salzburg, Austria & AIT Austrian Institute of Technology, Austria)

One of the big obstacles impeding progress towards full vehicular automation lies with machine decision making and the potential ethical consequences thereof – in particular in relation to dilemma situations. The discussions surrounding the “Trolley Problem” paint a picture from which a satisfactory way out is difficult to see: No matter which outcome is chosen in such a dilemma, human individuals come to harm, thereby rendering the decision leading to the outcome ethically problematic and undesirable. As a consequence, any decision algorithm that would propose to execute such an action would be equally unacceptable, which leads us to an impasse on how to design vehicles with ethically sound decision making … or so it might seem. In this talk, we will untangle the complex problem space of moral dilemmas and vehicle automation together. We first take a thorough look at dilemmas and their purpose in Philosophy, so that we can then explore various dilemma variations and finally discover why the problem posed by dilemmas is actually not part of the design space that is appropriate to deal with them as far as the decision-making process is concerned. We will then move the dial towards the future and put the lens on the true scope of ethically relevant aspects in relation to vehicle automation, in order to specify what we (should) mean whenever we talk about “ethical automated vehicles”.



This year we will have two keynote speakers:

  • Dr. Paolo Pretto (Virtual Vehicle Research Center, Graz, Austria)

Dr. Paolo Pretto holds a binational PhD (Cotutelle de thèse) in neural and behavioral sciences from the universities of Tübingen, Germany, and Padova, Italy, since 2008. He is Principal Researcher and Research Strategy Manager for Human Factors and Driving Simulation at Virtual Vehicle Research GmbH (AT) since 2018. Previously, he was leading the Motion Perception and Simulation team at Max Planck Institute for Biological Cybernetics for 7 years. His research activities focus on driver’s perception, comfort and ergonomics, human-machine interface and human factors in automotive. The aim is the understanding of how drivers perceive, decide, behave and communicate with modern and future technologies. The research tools consist of human-in-the-loop driving simulation and field testing with quantitative assessment of subjective sensory experience. He contributed to important achievements like, e.g., the concept of fluid human-machine interface to support drivers in automated vehicles; the development of a cooperative safety system based on sharing drivers’ state among road users; the implementation of a procedure for comfort assessment of vehicle interiors in virtual environment.

  • Dr. Alexander Mirnig (Paris Lodron University Salzburg, Austria & AIT Austrian Institute of Technology, Austria)

Alexander Mirnig is a Senior Researcher at the University of Salzburg, Austria, Department of Artificial Intelligence and Human Interfaces and a Scientist at the AIT Austrian Institute of Technology, Center for Technology Experience. He is an ACM Member and IARIA fellow. He holds a Master’s degree in Philosophy and a Doctorate in Informatics. He is a contributor to the Austrian RDI Roadmap for Automated Vehicles as well as the DIN Standardization Roadmap for Artificial Intelligence and is the EC-appointed Ethics Advisor for the European Horizon project MC4. In his research, he focuses on human factors in automated passenger vehicles and public transport, Machine Ethics, and matters of trust in interacting with automated machines.


7th Human-Computer Interaction Slovenia (HCI SI) conference
University of Ljubljana, Faculty of Electrical Engineering, Ljubljana, 29 November 2022


The Human-Computer Interaction Slovenia (HCI SI) is the seventh conference in a series organised by the Slovene HCI community (ACM Chapter Bled). The primary target audience are HCI researchers and practitioners from academia and industry from the Alps-Danube-Adriatic basin; however, we welcome contributions from beyond this region.


Paper submission deadline: 1 November 2022 –> 8 November 2022
Work in Progress submission deadline: 1 November 2022 –> 8 November 2022
Decision notification to authors: 15 November 2022
Final versions deadline: 22 November 2022
Conference: 29 November 2022


Submissions should be related to any aspect of HCI technology, systems, devices, techniques, experience, application, methods, tools, theories, and new perspectives.

Submission Platform

All submissions should be uploaded electronically through the easychair platform.

Submission Format and Length

The conference uses the single-column CEUR-ART style template. We also prepared an Overleaf template. After clicking the link choose “copy project” in the Overleaf menu. You need to be registered and logged into Overleaf in order to be able to do that. The page lengths below refer to the CEUR-ART template.

We accept the following contributions:

  • Research papers 5 to 15 pages long including references.
    The length should be proportional to its contribution.
  • Work in Progress (Poster) papers 3 to 5 pages long including references.
    Work in Progress papers are particularly suitable for showcasing BSc/MSc students’ work. The submission is a description of the work in the form of a scientific paper (extended abstract). The authors will have to prepare the poster itself and bring it along to the conference


We will use a relaxed approach to anonymity where the authors choose what to disclose. The submission system EasyChair will be configured as double-blind so that the reviewers will not see the authors’ names unless the authors disclose them in the paper. Hence, it is up to the authors’ decision whether they wish to disclose their identity in the submitted PDF (thus being subject to a single-blind process) or not (double blind).


The preferred highly encouraged language is English, although submission in Slovenian will also be considered (in this case, please provide an English language translation of the title and the abstract, following the instructions).

Publication and Copyright

The papers will be published in CEUR-WS.org as open access under Creative Commons Attribution (CC-BY 4.0) license. The copyright remains with the papers’ authors.

Presentation Format

Accepted papers will be presented at the conference. At least one author of each paper must register and present their work (registration is free). The expected presentation time for full paper is 12 min + 3 min for Q&A.
