foreword CAVI is an interdisciplinary research centre for the Arts and Sciences at Aarhus University, Denmark. CAVI’s researchers primarily have a background in interaction design or digital aesthetics, although some have a background in computer science. We carry out research through design, in the sense of making practical design experiments aimed at gaining insight into interaction design – design process, as well as interface and use. Many of our researchers have a background in participatory design, which explains our concern with the context for which we are designing. A strong interest in exploring the design of engaging experiences is a persistent thread throughout our research portfolio. In Book of Abstracts 2012 we present selected research results as they have been published during the recent couple of years in areas such as digital culture and

aesthetics, child computer interaction, urban computing, media architecture, as well as design processes. In several of our projects, we have worked closely with external partners, for instance, technology providers and other businesses. In the area of cultural computing, we have worked with independent artists, as well as cultural institutions such as museums. Collaborating closely with external partners pushes us to take context seriously, and to make full-scale installations, which may be put into the real world.

Three areas of interface research that have garnered much attention in recent years are tangible interaction, tabletop interfaces, and 3D projection. Tangible 3D tabletop is a novel interface, which draws upon and combines elements from these three areas. The tangible 3D tabletop thus combines a rear-projected tabletop interface with a 3D engine, which enables precise projection of content from multiple top-mounted projectors, onto tangible objects placed on the table. Since the tangible 3D tabletop is a novel type of interface, it may be approached from a number of research angles. Our main approach in the paper is from a design perspective, and we therefore focus on the challenges and potentials for interaction designers who wish to develop applications for the tangible 3D tabletop. technical setup The tangible 3D tabletop developed by CAVI consists of a translucent table surface under which a projector (1) and a camera (2) are mounted. Above the are mounted. The projector beneath the table displays visuals on the table, while the projectors mounted around the table project content onto tangibles (3), which

computers, each of which uses the commercially available 3D game engine, UNITY, to render images projected onto the tangibles by the projectors mounted

design principles Based on our experiences from developing applications for this interface, we outline a series of general design principles concerning the characteristics of, and interplay among the components of the system. We furthermore present a number of applications developed for the tangible 3D tabletop in order to explore the underlying design principles and potentials. These applications show ways in which tangible 3D tabletops can be employed maps such as city maps and building blueprints. design considerations Our analysis of these cases has resulted in three overall design considerations: Firstly, tangible 3D tabletops can combine and connect both the content and functions of tangibles and tabletop surface; secondly, there is a rich potential for employing dynamic content on tangibles that can simultaneously serve as displays and input devices; and thirdly, a new range of visual of the 2D tabletop surface and the 3D tangibles. While we are encouraged by face, it is also evident that there are many aspects that remain to be addressed, including technical limitations and in-depth studies of real-life use applications of the system.

sense-making, engaging conversations, and playful engagement The Mejlby stone installation is now a permanent installation at a cultural and historical museum in Randers, Denmark, and, based on observation as well as interviews of museum visitors, we have analyzed how the installation supports sense-making, engaging conversations, and playful engagement. Sense-making can be described as a fact-based, audience-to-installation level but also occurs at more self-identifying level, where the audience starts to relate to the people and the story behind the stone. The engaging conversation can be seen as a human-to-human relationship mediated by the stone. The playful engagement is a more unconscious audience-to-installation level that leads to self-direction in the experience. The self-directed elements of experience are especially interesting. In these situations the visitor is so much in trolling oneself. In these cases goal and means fuse and the audience take the experience into their own hands.

Many of the uses of 3D projection borrow from more well-established forms of visual means of expression, sometimes tweaking them slightly and at yet other times, using juxtapositions of traditional visual expressions and 3D projection to create

To it is productive to investigate Research through Design at a micro-level, by addressing the dynamics of research and design as unfolding throughout a design process the journey of holger the dane As our principal case, we consider the design of a three-dimensional projection installation, The Journey of Holger the Dane, projected on a white concrete statue of the legendary Viking warrior, Holger the Dane. Three-dimensional projection on physical objects is a particular kind of spatially Augmented Reality, which augments a physical object by projecting digital content directly onto it. In the case of The Journey of Holger the Dane, we have used 3D projection to add a digital layer directly onto the statue, bringing elements of the legends told about Holger the Dane to life for the audience. As part of the installation, we meet the six fairies who endowed Holger the Dane in his cradle with gifts such as immortality, strength, courage, and attractiveness to women. Several of the important and dramatic events in Holger’s life, such as his imprisonment by Carl the Great, and his defeat of the giant Burmand, are staged. Finally, the old warrior

We analysed material collected from 18 key events during the process, in order to identify the on-going dynamics. Based on the analysis, we establish how the interplay evolves in a complex structure, where the design and research interests continuously couple, interweave, and decouple. Coupling is a dynamic that unites design and research interests, and thereby establishes a framework for, as well as a set of constraints on the further steps in the process. Interweaving is a dynamic wherein one activity or material informs both design and research interests. Decoupling

For instance a cardboard box and some shops was a boundary object. From a research perspective, the materials were used to inquire into how three-dimensional spatial and physical representations facilitate the creation of a future scenario. From a design perspective, the workshop materials supported communication about visitors’ patterns of movement during the discussion of design ideas.

The interplay between research and design interests evolves through an on-going, dynamic process, in this case, starting with the coupling of separate design and research interests, and proceeding to their being thoroughly interwoven then subsequently untangled, and moreover, going from design and research interests being equal focuses, to one or the other being the conspicuous focus. design artefacts as boundary objects The design artefacts of the process may be considered boundary objects in a research through design process in the sense of being entities that may be used for both research and design purposes

In this paper, we focus on one particular kind of urban computing, media façades, which is the general term for incorporating displays as an integrated part of a building’s façade. Using media façades as a subcategory of urban computing, our research focus revolves around coming to grip with sense-making and social mediation as part of identifying key characteristics of interaction with media façades in an urban setting. Our approach strongly relies on research-through-design by conducting real-life design interventions where we have taken advantage of our in order to explore aspects of urban comfuel for our discussion is Aarhus by Light. Aarhus by light Aarhus by Light was a two-month social experiment with an interactive media façade at the Concert Hall Aarhus in Denmark. In the façade lived small creatures of light. When you approached the concert hall you entered their world, which was also a part of the city. They were social beings always (or mostly) happy to see you. On the central path leading visitors towards the concert hall were three illuminated zones, each covered with carpets in bright colors. In these zones, camera tracking translated the visitors’ presence and movements into digital silhouettes on the façade, and through the silhouettes, visitors could caress, push, lift and move the small creatures. The creatures would wave back,

– families, groups hanging out, or other social gatherings. Using Aarhus by Light as the principal case, we have zeroed in on some of the challenges when designing for large media façades in urban space. We have in particular addressed the open-ended but framed nature of interaction, which in conjunction with varying interpretations enables individual sense-making. Moreover, we have contributed to the understanding of situational interaction in relation to distributed attention, shared focus, dialogue, and collective action. In addition, we have elaborated on the challenges for interaction designers encountered in a complex spatial setting calling for a need to take into account multiple viewing and action positions.

Looking at quantitative and qualitative data we may argue that the Aarhus by Light is supporting ‘situational interaction interaction: 1) Distributed attention, 2) tive action. The installation is not only mediating social interactions, it is facilitating a very wide range of social interactions and transitions between these levels of interaction. The relation patterns highlight the fact that most of the interactions are part of larger social relations. Even though there are examples of individuals interacting with the media façade alone (but still in public space), most of the interactions

In order to obtain a better idea of how the various content would work in full scale, we ran a test, working with the projection of content on a wall, approximately four metres by twelve metres in the backyard of our laboratory. We also developed a virtual 3D model of the pavilion, including projections of the 3D model onto a scale physical model (1:100).

One of the main obstacles in tangible and embedded interaction design is the complexity of tools and competences required for sketching and casual prototyping. Whether for educational, designerly, or artistic purposes, various other projects have addressed this challenge, and a range of tools and platforms have emerged.

Ease of use applies to the point of view of the prospective interaction designer (whether formally trained or not): no steep learning curve, easy initialization and setup, requiring no or minimal programming skills or hardware experience. Thereby, we aim to accommodate users who are not (yet) technically skilled, typically designers, students, and artists. dul radio vs other platforms The feature set of any platform represents er traditions, standards, needs, end-product perspectives, and even pedagogy and ethics. But in general, the development environments tend to favor either ease of use or low-level hardware control.

tiation lies in the optimized performance with regard to sketching sensor-based interaction. Reducing complexity in sketching is another purpose of DUL Radio. Also here, opposed to what we call an “open platform” approach (e.g. Arduino), DUL Radio has been built with a deliberate goal to hide both hardware and software complexity under the hood, so to speak, but without limiting too many relevant features, while still leaving open the option of setting free the access to hidden complexities at some later stage.

teaching sensor-based interaction design From the early stages of developing DUL Radio, it has been a main objective to make it well suited to be used in project-based design courses at universities and design schools. We now have a fair amount of experience with teaching the use of the platform—in 2011 a total of more than 80 students—and we have an evaluation based on questionnaries action design course taught at 3rd or program. For another part of the survey, the students were asked to evaluate their own abilities in programming and/or hardware experience, all marking their abilities as none or almost none. The questionnaries revealed students generally found it easier to understand the (simpler) concept of the DUL Radio than the (more complex and versatile) Arduino-platform.

For a number of years, we have explored the notion of ’engagement’ through our experimental work. This has led to discussions, both among ourselves and with our peers within interaction design, regarding the nature of engagement and the ways in which it unfolds when people encounter interactive systems and installations. The notion of engagement is so broad productive to consider engagement as a perspective on interaction, rather than on engagement focuses our attention on how people, as resourceful individuals and groups, invest their time, skill, knowledge, and imagination in interactive environments. While it has proven productive to study engagement with particular technologies these technologies do not exist by themselves. Rather, they are parts of larger assemblies, wherein various technologies, physical properties, and forms of cultural practice shape people’s engagement with them. From our perspective, a focus on the individual object is thus too narrow for understanding people’s engagement with technology; an account is needed that is capable of capturing engagement as a product of relations between physical, cultural, social, and content-related elements. Moreover, we see a need for studying the dynamics of engagement as it unfolds in concrete situations, and with assemblies of technologies.

Our second case, the Hydroscopes, was an interactive installation exploring new potential for engaging experiences at museums and science centres. Third and last, the LEGO Table was an interactive installation that explored new potential for digital marketing at a department store. From an analysis of these three cases in conjunction with one another, we have found that engagement with interactive installations may be construed as a highly relational phenomenon, characterized by the interplay between physical and spatial conditions, socio-cultural practices and constructs, and the content of the installations. In this paper, we focus on the dynamics between these four properties, and on the transformations that occur during interaction, both between these aspects (for instance, transformations that concern both social and physical aspects) and within them (for instance, transformations of social aspects). stances from each of the three cases, we explore how engaging interaction may be understood as a relational, dynamic, and transformative phenomenon involving the above-mentioned four aspects as crucial elements. reference standing the Dynamics of Engaging InteracACT 2011, (212-229).

Digital Technology can support the creation of dialogical spaces in the museum, audiences to engage in the ongoing construction and reproduction of cultural heritage creating novel connections between people and between past, present and future. In this way, digital technology can contribute to the creation of emergent exhibitions in which the exhibition is created in dialogue between audiences and the museum. We present experiences from a current research project, the Digital Natives exhibition, in which digital technology was designed as an integral part of the exhibition to encourage dialogue between audiences and the exhibition materials. Two interactive installations, Google my Head and DJ Station, are presented below. google my head Google my Head is an interactive tabletop installation running on a PC connected to a 72” Evoluce One LCD multi-touch display. The Google My Head installation encouraged audiences to browse in a repository of Digital Natives online and mobile updates, pictures and videos continuously posted on the multi-touch screen drawn from a database. At the installation, visitors were confronted with the task of completing the sentence “Digital Natives are: ......” While browsing through the digital traces from various social media, they could choose up to four utterances, pictures or videos that caught their interest and supported their completion of the sentence. The chosen samples were stored in a docking placed at each of the narrow ends of the table. When

The widespread use of Participatory Deproaches and conceptualizations exist in ful approach is to rekindle a concern for values in design, focusing upon values as the engine that drives our activities in PD. Drawing from our own PD projects, this paper shows how this can be accomplished: through designers enacting their appreciative judgment of values while engaging in a dynamic and dialogical process of cultivating the emergence of values, developing them, and supporting their grounding. Participatory design When Participatory Design (PD) began nearly four decades ago amidst the explicitly political climate of Scandinavia, this design movement was forged with a commitment to values. PD makes explicit the critical, and inevitable, presence of values in the system development process. In addition, working with values in the design process is seen as an ethos that respects people’s democratic rights in that the people whose activity and most directly by a design outcome ought to have a substantive say in what that outcome is. But as PD is embraced by many far beyond Scandinavia, infused with diverse traditions and disciplines, this design practice has been transformed into one that is associated with a rich diversity of theories, practices, analyses and actions. However, this transformation has generated some lively discussions and

methods and participation in PD practice, which may have shifted the focus away from values. working with values To illustrate how we work with values and demonstrate how methods and stakeholder participation can be used to engage with values, we will draw from three design cases: two in museums and one in a primary school. Our work with values is a dialogical process – where we orchestrate, facilitate and create opportunities for dialogue amongst stakeholders. And it is through this dialogue that we cultivate the emergence of values, develop the values and ground the values during the design process.

ther developed through PD methods that encouraged dialogue, through collaborative games and problem solving activities before it was eventually grounded through design. A values-led design approach We contribute to furthering current PD practice by describing and explicating this dialogical process of emergence, development and grounding of values during design. We also highlight the crucial role that the designer’s appreciative judgment system of values plays in this process. Finally, providing further insights into this process will contribute to illustrating a way to conceptualize a values-led approach for those wishing to engage with values in their PD practice.

Examples from these cases reveal how choice of methods and in turn how we utilized the method to address values in design choices. This pervading concern for values also shaped the ways we work with stakeholders, such as how we facilitated the negotiation of design dilemFurther, we demonstrate how our concern for values transformed our design ideas throughout the design process as

This paper explores how technology may be harnessed to support a particular human value, Environmental Sustainability. In order to focus our discussion, we describe an urban video installation, CO2ncally with this value in mind.

While the installation brought a particular aspect of environmental sustainability to the fore, it was found to also encourage through engaging in public conversations. This provides insights into an alternate approach whereby such values could be engendered. Instead of the commonly used ‘big stick’ approach that pushes values pertaining to environmental sustainability in a didactic manner upon individuals, the installation encourages personal dialogue with regards to this value. This approach is more open and allows people to engage with the values on their own terms whilst respecting their personal circumstances, contexts and historicity. As we will demonstrate, through appealing to the individual’s sense making, there is potential for individuals to engage more actively through their own volition and in turn even leading to attitudinal change. cally upon human values.

The climate change debate provides an excellent example of a contentious issue that has become so overexposed that it is hard to say anything that will be heard or noticed. We present an analysis of two interactive climate projects – Climate on the Wall and CO2nfession/CO2mmitment – aimed at engaging people actively in the issue of climate change. The analysis is carried out based on empirical knowledge from these projects and framed by three theoretical lenses on experience, towards central issues for designers and users of urban media and interfaces.

Digital technologies have created profound changes in civic communication. From news websites and citizen services, over social networking services and microblogging, to crowdsourcing of news reporting by citizen journalists and political action orchestrated through digital means, the constraints of print and electronic mass media are being transcended by digital platforms.

Modium, have become the most ubiquitous communication platform in existence, around 7 billion people. In other words, we are approaching a state where every person has a digital voice. But while the sheer quantity of technological means and availability of access to contribute one’s voice and participate in public debate is undisputed, the notion of voice in civic communication is another matter entirely.

The term ‘voice’ may mean many different things: from Aristotle’s distinction between voice and speech, which in contemporary understanding points to the notions of voice as sound versus voice as expression of (political) opinion; to Couldry’s voice as a process versus voice as a value. The underlying argument Couldry sets out is that in order for public voice to be meaningful, a society must place value in public voice as a pro-

The concept of scripted space enables us to discuss how ubicomp – a migration from the screen and the desktop towards integrating computers and networks into our surroundings – is related to new developments in public urban space. ‘Scripted space’ highlights the written, coded quality of ubicomp - literally meaning adding scripts to the space and signs surrounding us. As such, ubicomp does not result space – where the computer becomes invisible – but is seen as continual development of the urban experience, where urban signs become operational, and computing continues to be an important part of our conscious experience. How does the urban scripted space manifest itself? The forefront of scripted spaces is often described as post-urban spaces, such as Las Vegas and Los Angeles, or high-tech spaces, such as Singapore or Tokyo. But the mediation of space more ordinary cities.

Also, text messages setting up social encounters can be considered to play an important role in the way people make their way around urban space. Stickers or posters, virtual maps, and other web 2.0 services, indicate that the mobile personal computing space is not only about the isolated individual, but also the individual’s interface to the public space. However, as implied by, for instance, Apple’s successful range of ‘iProducts’ (iBook, iPod, iPhone), this interface is still privileging the individual and rations of urban, social space.

ers are connected to each other, and to other spaces. Compared with earlier ways of congregating and inhabiting urban space, this social formation is often strangely invisible to outsiders in physical urban space. A public, writerly scripted space The scripted space of urban ubicomp creates individual experiences of the city as a personal, public playground (a borderless café) or, less frequently, the basis of social encounters, communication, and debate (a borderless agora). It is, however, not the only way to participate in the public, scripted space of the city. What happens when people are not tion in urban public life, the scripts themselves? This experience is a call for action where the city dwellers take control of the urban scripts and become ‘writerly’ by creating, hacking, and rewriting the city.

hypertextual connectivity and linking Most of the urban dwellers have mobile phones, credit cards or other kind of keys to the scripted space. Cafés and shops have websites and emails addresses, and provide wireless internet access, and get on-line. Many urban dwellers probably also have their own networks of social links, favourite sites, and perhaps even exchange tags and preferences. In this way, an urban space and its dwell-

Smart city is currently a popular concept for the development of media architecture, ubiquitous and embedded computing infrastructures, and other urban interfaces. In this project, we discuss – and experiment with – aspects of how the smart city may be developed in relation to citizen participation in an urban democratic culture. We identify some problems surrounding current social and mobile media platforms such as Facebook or iTunes, which regard its users as ‘prosumers’ in a controlled consumption scheme where social activities and sharing are controlled and closely monitored through centralized commercial platforms, and where consumers become licensees or renters, rather than owners with the rights to resell, lend, and reuse their content. This model is contrasted with more open concepts of a public sphere, or weSpace from urban history and Free Software. Furthermore, we introduce the project, Instant Kafé, which is an experimental, conversational platform for exploring this weSpace of the coming smart city, and creating a discussion around business models and techevents and locations at an 18th century festival in Aarhus. Instant Kafé consists of a number of conversational elements: – Talkaoke is a mobile talk show, in which anyone can join. It was originally developed in London by the artists’ collective, ‘The People Speak’, and has been further developed in collaboration with them and with us, for instance, for the COP15 UN

Building on French writer Georges Perec’s work, we further argue that Ekkomaten is an extraordinary machine that questions a range of underlying assumptions about everyday life in the 18th century and today. Additionally, through its physical and interactive design, Ekkomaten points both back and forward in time, thus quesof the future, and current ideas about digital futures as smooth and seamless, and adds a new – or rather ‘old’ – kind of materiality to the interaction.

Speaking Code begins by invoking the “Hello World” convention used by programmers when learning a new language, helping to establish the interplay of text and code that runs through the book. Interweaving the voice of critical writing from the humanities with the tradition of computing and software development, it aims to undermine the distinctions between criticism and practice and to emphasize the aesthetic and political implications of software studies. Not reducible to its functional aspects, program code is understood as both script and performance, and is in this sense like spoken language--always ready for action. indeterminacy Although the analogy between program code and speech acts has become rather commonplace since its suggestion by Terry Winogrand and Fernando Flores in indeterminacy they share, as with the example of live coding, where the writing of the software happens at the same time as performing with the software. Programmers express themselves through the use of program languages, the book suggests, in ways similar to other human communicative expression through language and gesture. They do this through their manipulation of layers of representation,

including symbols, then words, language, duction of software prototypes, artworks, programming languages, and improvised performances that embed the activity of programming in the improvisation and experience of software art in general. On this last point, the practice of live coding its writing, working, and creative use, establishes an unstable relation to its output. In this sense, although of course code largely determines its output, the broader apparatus including the idiosyncrasies of the programmer provide indeterminate outcomes and help to stress the expressive dimension of software production as a whole. Performativity Speaking Code examines the expressive and performative aspects of programming; alternatives to mainstream development, from performances of the live-coding scene to the organizational forms of peer production; the democratic promise of social media and their role in suppressing political expression; and the market’s emptying out of possibilities for free expression in the public realm. It becomes a defense of language against its invasion by economics, arguing that speech continues to underscore the hu-

man condition, however paradoxical this may seem in an era of pervasive computing. If lived experience is ever more prescribed through scores, scripts, and programs, then the challenge for those making program scripts that underscore these procedures is to open up aesthetic and political possibilities of recombination and free the imagination (and code) to further use. Thus the performativity of code, in live coding or code acts, demonstrates the potential for collective intelliposes coding practices that have not only a body but also a body politic.

the new millennium, a wave of interest in the climate crisis culminated with the United Nations Climate Summit, COP15, waned somewhat after following the failure to reach a binding agreement. Digital climate art was part of this wave, exploring the complex new and prevalent connections between technology and nature that climate change puts on the agenda. From an aesthetic perspective, the climate crisis may be seen as an epistemological crisis (apart from the serious environmental challenges it presents). We are trying to recognize and address something of which we see early signs, but must act on before it is too late, and the evidence of irreversible catastrophic changes in our environment become incontrovertible. We still primarily perceive climate change as mediated phenomeels, and visualizations, whereas when we look out our windows, it is debatable whether the weather we experience is a sign of the climate crisis, or is just unusual. We cannot immediately perceive CO2 we have to turn to the mediated presentation of instruments, other technology, and science, in order to recognize the extent of the crisis. Consequently, climate change introduces us to the fact that our immediate environment, the weather and climate, are becoming mediated by political interpretation. Complex data, models, interpretations, and calculations

interfere with our immediate sensations, even in the deep countryside, when there are no computers or interfaces in sight! We argue that because of its inherent technological form and mediated character, digital art is well-equipped to explore such complexities, especially if the art explores its own media in a critical way, as much critical media art does. Therefore, it is worth researching the aesthetics and poetics of digital climate-criencing climate change. After introducing the discussion, we discuss digital climate art from an epistemological and a political perspective, mana’s interior installation, ‘Post Global Warming Survival Kit’, a work that makes us explore and experience our blindness by installing a post-climate-disaster scene in a completely darkened room, so that it can only be experienced with night vision goggles. The other project is Planetary Pledge Pyramid (The People Speak, CAVI), a project that strives to give people a voice in the discussions at the COP15 Copenhagen climate summit through a newly developed application on Facebook, and developments of The People Speak’s formats, such as the Talkaoke talk shows, and the live game show ‘Who Wants to Be?’, held on the last evening of COP15. Consequently, this is an experiment in using media and mediated forums to create engagement and constructive activism and debate.
