Innovation agendas for care are increasingly flanked by demands for participatory and transdisciplinary approaches. However, especially in care robotics, it is difficult to shift the focus to early involvement of people and lifeworlds. We present the integrated methodology of a care robotics project and introduce inter- and transdisciplinary steps...
Chapter
We present the concept and technical realisation for a cup that moves and lights up so as to bring itself to the attention of a person with dementia, to trigger taking a sip as a response. The concept is aimed at people with dementia in home or resident care who still have the ability to act, but tend to mentally drift away and thus require externa...
Conference Paper
Very young children (below three) are characterized by sensory-motor exploration and pre-cognitive development. There is little work on interactive toys for this age group. This raises the question of what interactions are developmentally appropriate at this age. We here propose recommendations for designing meaningful interactive toys, gained from...
Article
When assessing the value of visualizations, researchers traditionally focus on efficiency, comprehension, or insight. However, analyzing successful data physicalizations leads to a deep appreciation for hedonic qualities. Informed by the role of emotion in psychology, art, design, marketing, and HCI, we argue for an expanded definition of value, ap...
Conference Paper
Research on product experience has a history in investigating the sensory and emotional qualities of interacting with objects. However, this notion has not been fully expanded to the design space of co-designing smart objects. In this paper, we report on findings from a series of co-design workshops where we used the toolkit Loaded Dice in conjunct...
Conference Paper
Dyscalculia affects comprehension of numerical mathematical problems, working with numbers and arithmetics. We describe our work on a training system for an exercise that trains connections between verbal and numerical representations of numbers and finger counting. Fingers support embodied cognition and constitute a natural numerical representatio...
Conference Paper
In previous work, we have developed the theoretical concept of Critical Experience and the Participatory Evaluation with Autistic ChildrEn (PEACE) method. We grounded both in a series of separate case studies which allowed us to understand how to gather more and richer insights from the children than previously. This is crucial for child-led resear...

Digital technologies are being introduced in museums and other informal learning environments alongside more traditional interpretive and communication media. An increasing number of studies has proved the potential of digitally mediated cultural heritage experiences. However, there is still a lot of controversy as to the advantages and disadvantag...
Chapter
In the current chapter, we focus on evaluation studies of visitor behaviour and interaction in-situ, on the museum floor. On a strategic level, there is the distinction between front-end evaluation (done to gain insights informing exhibition planning, in particular on its audience), formative evaluation (done to improve prototypes in an iterative d...
Chapter
Poor design can result in broken exhibits-visitors either do not know how to use an exhibit and think it is broken, or they unintentionally break things (Kollmann, 2007). Besides usability and apprehendability (so visitors know within a few seconds how to interact), good design requires good choice and design of content so that it appeals to visito...
Chapter
Digital technologies for museums not only address different themes of a possible visit, as we saw in Chapter 1, and are not only deployed for varying exhibition settings, they can also be strikingly different in terms of which physical-digital interaction they afford and by which hardware and software set-up. This chapter presents key interaction f...
Chapter
Engagement strategies promoted by cultural institutions increasingly feature participatory elements (Simon, 2010; Kidd 2014; Tallon and Walker, 2008; Clarke et al., 2015), including the possibility for visitors to respond and contribute to exhibitions in various forms. Giaccardi (2012) argues that a lively line of work on heritage as a participator...
Chapter
A number of factors influence the potential success of museum installations and digital interactivity. Similar to other areas of Human-Computer Interaction (HCI), design needs to be aware of the characteristics of the context of use, which influence its fit with the setting and with the institution, adoption and appropriation of the technology, and...
Conference Paper
We present a textile sensor, capable of detecting multi-touch and multi-pressure input on non-planar surfaces and demonstrate how such sensors can be fabricated and integrated into pressure stabilized membrane envelopes (i.e. inflatables). Our sensor design is both stretchable and flexible/bendable and can conform to various three-dimensional surfa...
Conference Paper
We describe the development and user testing of an ambient display for autonomous vehicles. Instead of providing feedback about driving actions, once executed, it communicates driving decisions in advance, via light signals in passengers" peripheral vision. This ambient display was tested in an WoZ-based on-the-road-driving simulation of a fully au...
Conference Paper
For pedestrian navigation support, we report on how the feeling of being in control about receiving updates impacts navigation efficiency and user experience. In an exploratory field study, 24 participants navigated to previously unknown targets using a wristband which conveyed tactile information about targets' bearing. Information was either pull...
Conference Paper
In the 1920s, Oskar Schlemmer, artist in the Bauhaus movement, created the Triadic Ballet costumes. These re-strict movement of dancers, creating new expressions. In-spired by this, we designed an interactive wire costume. It restricts lower body movements, and emphasizes arm movements spurring LED-light 'sparks' and 'waves' wired in a tutu-like co...

Although public displays are increasingly being deployed in everyday situations, they are still mostly used as auto-active information sources. Adding interactivity can help to attract and engage users. We report on the design and in-the-wild evaluation of an interactive advert for a public display in a tourist information center. We evaluate and c...
Conference Paper
Capturing and describing the multi-faceted experiences autistic children have with technologies provides a unique research challenge. Approaches based on pragmatist notions of experience , which mostly rely on empathy, are particularly limited if used alone. To address this we have developed an approach that combines Actor-Network Theory and Critic...
Conference Paper
We present findings from an interview-based study of the pervasive mobile multiplayer game Ingress. Our study focuses on how boundaries between (1) everyday life and play and (2) 'real' and game space blur in pervasive gaming. We present findings on how the game is integrated into everyday life and affects players' mobility patterns, and on how pla...
Conference Paper
We present a media art installation based on Human-Plant Interaction, which aimed to increase people's awareness of nature via a light-based reaction to touching the plants. We describe the setup and conceptual design and discuss how such an interactive installation might affect usage and overall attractiveness for a central urban place.
Conference Paper
Developing media content for public spaces cannot be effective without a deep relationship with its location. Hence, an analysis of the location is required, especially when designing a novel medium carrying and matching the content and fitting the urban environment. We focus on our experience with an in-situ and a simulation-based evaluation appro...

Article
Humans have represented data in many forms for thousands of years, yet the main sensory channel we use to perceive these representations today still remains exclusive to vision. Recent developments now offer us opportunities to perceive data through different levels and combinations of sensory modalities. In this article, we survey the state-of-the...
Article
Based on case studies from a heritage/museum context, I present and illustrate the notion of “spatio-contextual embedding,” which conceptualizes installation designs that augment real objects and environments while keeping these primary focuses of attention. Key for this “embeddedness” is that interaction is contextualized within a meaningful setti...
Conference Paper
This paper explores the potential of tangible and embodied interaction for encouraging a multisensory engagement with museum objects and artefacts on display, by means of focusing on the subtleties of devising and planning for evaluation and audience research. Measuring the impact of new technologies is one of the main challenges identified in the...

Conference Paper
In this paper, we discuss the requirements and critical challenges for creating and staging interactive costumes in the theatre. Different to other types of performance, theatre costumes are secondary to acting. Our investigations are based on two practice-based case studies: a self-directed design research within a student project, and a collabora...
Conference Paper
In this paper we explore alternate projection and imaging mechanisms that don't rely on luminous sources, such as screens or LEDs. We investigate how sunlight can be used along a continuum ranging from non-informational aesthetic lighting to simple controlled reflections of sunlight that provide enough information to depict legible content. Rethink...
Conference Paper
Façade mapping events often assign a passive role to the audience. Due to the high pace of animations, restricted length of 12--20 minutes and audience size, integrating interactive elements is difficult. We present a case study of a façade mapping event that was designed as a Gesamtkunstwerk and total experience with several elements and phases, a...
