1. Introduction
The sixth version of the European Tangible Interaction Studio was hosted by ENAC (Ecole
Nationale de l'Aviation Civile, France) and took place onsite from November 6th to 10th 2022. In total
there were approximately 50 participants attending ETIS from 15 countries (Belgium, Czech Republic,
Estonia, France, Germany, Italy, Luxembourg, Netherlands, Portugal, Singapore, Spain, Sweden,
Switzerland, the United Kingdom and the United States). The theme of the ETIS conference was
“Ecological transition and mobility of the future”.
Tangible Interaction is a research field addressing areas at the border of the physical and the digital.
Nowadays many researchers, designers, developers and artists work in this area and a vast range of
products and applications are designed and produced accordingly. Besides, many research projects are
funded through research funds at a European and international level.
The aim of this meeting is to gather young European researchers in our field, to get them in touch
with internationally renowned researchers and to establish networks for their future. This studio was a
follow-up of the previous editions held in Bidart (2013), Fribourg (2016), Luxembourg (2017), and
Siena (2020). The idea is to provide a unique opportunity to train in the field of tangible interaction and
to discuss the research with professors and other young researchers.
Researchers with different backgrounds from both academic and applied/industrial research
participated in ETIS 2022. The studio included voices from industry and private research institutions
working in the field of tangible interaction. It aimed to provide participants with insights for applied
research possibilities, in order to bring tangible interaction principles out of the lab, in the everyday use.
Senior researchers from the industry and internationally known professors introduced different
topics related to tangible interaction from their different points of view.
2. Keynote speakers
Four keynote speakers were invited to participate in ETIS’22: Jörn Hurtienne (Julius-Maximilians-
Universität Würzburg, Germany), Alan Dix (Cardiff Metropolitan University & Swansea University,
UK), Wendy E. Mackay (Inria, France), and Kristina Höök (KTH, Sweden); the order is according they
were presented during the Studio. The abstracts of the keynotes are presented below:
1. Jörn Hurtienne, Professor of Psychological Ergonomics at Julius-Maximilians-Universität
Würzburg, Institute Human-Computer-Media
Title: Conveying the Abstract with the Physical: Primary Metaphors for Tangible Interaction
Abstract: More is up, important is big, honest is straight – so-called primary metaphors are mini
mental models of how the world works. They connect the abstract (for example quantity, importance,
moral behavior) with the physical-concrete (up-down, big-small, straight-crooked). Using primary
metaphors, we can design human-technology interaction that is simultaneously innovative, inclusive,
and intuitive. In his keynote talk, Jörn Hurtienne introduced the concept of primary metaphors based
on image schemas, demonstrated their potentials for tangible interaction, and identified questions for
further research.
2. Alan Dix, Professorial Fellow at Cardiff Metropolitan University and Director of the
Computational Foundry, a project of Swansea University, Welsh Government, and the European
Commission to promote ground-breaking digital research with a real impact on society
Title: Beyond the Wireframe: tools to design, analyse and prototype physical devices
Abstract: For many years interaction design was driven by the abstractions of WIMP (windows,
icons, menus, pointer). The details differ on desktop applications, web pages or smartphones and the
‘pointer’ has evolved from mice to trackpad and touch-based interactions, however, for many digital
applications, the central aspects are unchanged. What is different is that the screens we encounter, as
Weiser predicted, are everywhere: embedded in physical appliances such as showers and toasters and
situated in office walls and building facades. Furthermore, we are often engaging with digital
applications that have no obvious screen or where the screen if present is only a small part of the
interaction; these include voice assistants, semi-autonomous vehicles, and smart cities.
Even where the dominant interaction is focused on a screen, the nature of the interactive experience
is fundamentally affected both by the places where we interact and by the physical activities we are
doing: using a smartphone while sitting in an armchair and watching television, is very different from
thumbing a quick message whilst walking down a busy city road on a rainy night.
In his talk, Alan Dix described several design techniques and prototype tools that seek to address
the physicality of digital interactions including the physical nature of the device itself and the physical
context in which it is placed. They included ‘soft’ formal methods to describe physical aspects of
devices, ways to use video to model physical prototypes during early design and tools to encourage
designers to keep the context of use in mind even when working on largely screen-based interactions.
3. Wendy E. Mackay, Research Director, Classe Exceptionnelle, at Inria, the French National
Research Center for Computer Science
Title: Towards Intelligent Tangible Interfaces
Abstract: Rapid advances in artificial intelligence have led to a wide variety of intelligent systems,
but too little consideration of their impact on the people who use them. Researchers from HCI and AI
are working together on a new research area, « human-centered AI », which challenges traditional
research paradigms and shifts the focus from better AI algorithms to better interaction with users. In
her talk, Wendy Mackay discussed how we can design “human-computer partnerships” that take
optimal advantage of both human skills and of system capabilities, and how to design and create such
systems. She then discussed how this approach can be applied to the design of intelligent tangible
systems.
4. Kristina Höök, Professor in Interaction Design at the Royal Institute of Technology,
Stockholm
Title: Soma Design – intertwining aesthetics, movement and emotion in design work
Abstract: We are at a watershed moment: our relationship to technology is about to undergo a
dramatic and irreversible shift. With the rise of ubiquitous technology, data-driven design, and the
Internet of Things, our interactions and our interfaces with technology will look radically different in
the years ahead, incorporating changes like full body interaction, shape-changing interfaces, wearables,
and body- and movement-tracking apps. Kristina Höok discussed how we approach this challenge
through Soma Design — a process that allows designers to examine and improve on connections
between sensation, feeling, emotion, subjective understanding and values — and their relationships to
technology. She argued that by engaging in a soma design process we can better probe which designs
lead to: deepened somatic awareness; social awareness of others in the environment and how they are
affected by the human-technology assemblage; enactments of bodily freedoms rather than limitations;
making norms explicit; engage with a pluralist feminist position on who we are designing for; aesthetic
experience and expression; and, ultimately an aesthetic and ethical position on how to design for being
human.
3. Panel
In line with the conference theme, ETIS 2022 included a panel on the topic “Tangibility and
industrial downsizing”. Three panelists were invited to present their position: Anne Roudaut, who is
professor of Human-Computer Interaction and head of the Bristol Interaction Group in the Computer
Science Department at the University of Bristol, UK; Martin Hachet, who is senior researcher (DR2) at
Inria Bordeaux, member of LaBRI and team leader of Potioc (Inria, CNRS, Univ. Bordeaux); and
Aurélien Tabard who is associate Professor at Université Lyon 1, member of LIRIS (Université Lyon
1 & CNRS).
Anne Roudaut discussed how tangible object design is still tech-led and not material-centric enough
in contrast with non-digital objects, mainly because we are used to take available electronic
components. She illustrated a material-centric approach where e-ink was recycled from broken e-
readers and presented how to use more versatile and accessible tools to fabricate with raw electronic
materials such as e-pigment, morphing or sensing materials. Finally, she showed how bringing
fabrication tools and knowledge to end-users could bring more user self-awareness of materials and
how we consume them (changing the way we fix & recycle, reverting to a hacking society).
Martin Hachet presented his current project using mixed-reality and experimental economics to
encourage pro-environmental behaviors. In this approach, experiments based on game theoretical
models and mathematical predictions which are scientifically validated protocols ensure strong internal
validity of decision making and behavioral patterns. They may help to isolate and test pro- and anti-
social behavior, to integrate both individual and institutional (managerial) decision making and to take
into account the behavior of many participants interacting with the context but also among themselves.
This was for instance illustrated by the common resources game in which a resource that benefits all
can be appropriated by self-optimizing individuals.
Aurélien Tabard talked about situated visualization of pollution, including various data from sensors
to bioindicators. He discussed the limitations of current approaches (terrible sensing quality, senses
only one specific chemical element, high variability in space, limited representations, tech driven
community approach, naive discourse on empowerment). Then, he presented the use of lichens as living
sensors, indicative of nitrogen deposition (NOx) from either anthropogenic or natural sources, and how
to turn the environment into a visualization (biomonitoring). He explained that the latter approach has
many benefits, including engagement and strong relationship to context, scalability in space (from
bacteria to trees) and in time (little to no maintenance required over years), integrated sensing,
processing and display abilities, and built-in messiness that surfaces sensing challenges.
The second part of the panel allowed participants to express their ideas through an online
brainstorming on the miro platform (https://miro.com/), with a board prepared by Laetitia Bornes, PhD
student at ENAC. Post-it notes written by ETIS attendants where classified into categories relevant to
the problem, and aligned along the axes of the X-curve model which represents the transition processes
in crisis contexts.

6. Conference Theme
The theme “Ecological transition and mobility of the future” was chosen as the conference theme
for ETIS’22. Mobility was an obvious choice because ETIS’22 was hosted at ENAC, the French
university for civil aviation. In the past years, ecological transition has become a priority for ENAC in
order to attenuate the impact aviation has on the climate of our planet. The two main parts of the
conference theme were represented in the program through the following aspects:
Ecological transition:
• Paper « Thinking about Eco-feedback and Smart Plugs via a Survey and Thematic
Analysis » (Casado-Mansilla et al.)
• Panel “Tangibility & industrial downsizing” (see section 3)
• Decision to use public transport rather than renting busses
• All breaks offered a vegetarian or vegan option
Mobility of the future:
• Visit of « Cité de l’espace » (Space City) in Toulouse
• Paper « Tangible interactions in control centres for railway traffic management » (Malier
et al.)
• Workshop “Tangible Interaction in the (General) Aviation Cockpit” (Feger et al.)
• Workshop “Dronible: Operating drones with Tangible objects” (Garcia et al.) in the ENAC
flight hall
• Visits of the simulators of air traffic control and aircraft at ENAC
