Collaborative creativity: The Music Room
In this paper, we reflect on our experience of designing, developing and evaluating interactive spaces for collaborative creativity. In particular, we are interested in designing spaces which allow everybody to compose and play original music. The Music Room is an interactive installation where couples can compose original music by moving in the space. Following the metaphor of love, the music is automatically generated and modulated in terms of pleasantness and intensity, according to the proxemics cues extracted from the visual tracking algorithm. The Music Room was exhibited during the EU Researchers' Night in Trento, Italy

Contact through canvas: An entertaining encounter
When meeting someone new, the first impression is often influenced by someone's physical appearance and other types of prejudice. In this paper, we present TouchMeDare, an interactive canvas, which aims to provide an experience when meeting new people, while preventing visual prejudice and lowering potential thresholds. The focus of the designed experience was to stimulate people to get acquainted through the interactive canvas. TouchMeDare consists of a flexible, opaque canvas, which plays music when touched simultaneously from both sides. Dynamic variation of this bodily contact is reflected through real-time adaptations of the musical compositions. Two redesigns were qualitatively and quantitatively evaluated and a final version was placed in the Lowlands Festival as a case study. Evaluation results showed that some explanation was needed for the initial interaction with the installation. On the other hand, after this initial unfamiliarity passed, results showed that making bodily contact through the installation did help people to get acquainted with each other and increased their social interaction
An Analysis of Input-Output Relations in Interaction with Smart Tangible Objects
This article focuses on the conceptual relation between the user?s input and a system?s output in interaction with smart tangible objects. Understanding this input-output relation (IO relation) is a prerequisite for the design of meaningful interaction. A meaningful IO relation allows the user to know what to do with a system to achieve a certain goal and to evaluate the outcome. The work discussed in this article followed a design research process in which four concepts were developed and prototyped. An evaluation was performed using these prototypes to investigate the effect of highly different IO relations on the user?s understanding of the interaction. The evaluation revealed two types of IO relations differing in functionality and the number of mappings between the user and system actions. These two types of relations are described by two IO models that provide an overview of these mappings. Furthermore, they illustrate the role of the user and the influence of the system in the process of understanding the interaction. The analysis of the two types of IO models illustrates the value of understanding IO relations for the design of smart tangible objects

Meeting duet : challenging people into a body language of meeting
With the introduction and incorporation of novel interactive technology in product design, products are increasingly designed as facilitators or mediators of interaction. This Perspective opens the way to a specification of this focus, namely designing products as a motor of socio-cultural activities and events. Here the product’s form and behavior should, more than ever, be designed with the intention to engage people in a form of contact with each other. In this paper we present an educational project that aims at designing a meeting event on the festival ‘a camping flight to Lowlands paradise’. The project is based on the Design Movement approach, where products are designed for, and as part of, a Choreography of Interaction; in this case as part of a meeting event at Lowlands. In this paper we show how a product design originates from the creation of a social cultural event. Moreover, we show the effect of designing products from a choreographic perspective and with focus on people’s body language and dynamic interplay
Moving tangible interaction systems to the next level Citation for published version (APA): Reflecting on the Foundations and Qualities of Tangible Interaction
Abstract In the past decade, the field of Tangible Interaction (TI) has gained significant interest. As a result, numerous systems, theories and frameworks have been developed with this vision in mind. This has led to various instantiations of TI that seem developed to make digital information tangible, rather than to optimally use and combine all important qualities of TI. We believe that TI has more to offer than what has been used advantageously so far. Therefore, this paper reflects on the foundations of TI and identifies three qualities of control and representation in TI based on existing systems, theories and frameworks

A GH81-type β-glucan-binding protein facilitates colonization by mutualistic fungi in barley
Cell walls are important interfaces of plant-fungal interactions. Host cell walls act as robust physical and chemical barriers against fungal invaders, making them an essential line of defense. Upon fungal colonization, plants deposit phenolics and callose at the sites of fungal penetration to reinforce their walls and prevent further fungal progression. Alterations in the composition of plant cell walls significantly impact host susceptibility. Furthermore, plants and fungi secrete glycan hydrolases acting on each other's cell walls. These enzymes release a wide range of sugar oligomers into the apoplast, some of which trigger the activation of host immunity via host surface receptors. Recent characterization of cell walls from plant-colonizing fungi have emphasized the abundance of β-glucans in different cell wall layers, which makes them suitable targets for recognition. To characterize host components involved in immunity against fungi, we performed a protein pull-down with the biotinylated β-glucan laminarin. Thereby, we identified a glycoside hydrolase family 81-type glucan-binding protein (GBP) as the major β-glucan interactor. Mutation of GBP1 and its only paralogue GBP2 in barley led to decreased colonization by the beneficial root endophytes Serendipita indica and S. vermifera, as well as the arbuscular mycorrhizal fungus Rhizophagus irregularis. The reduction of symbiotic colonization was accompanied by enhanced responses at the host cell wall. Moreover, GBP mutation in barley also increased resistance to fungal infections in roots and leaves by the hemibiotrophic pathogen Bipolaris sorokiniana and the obligate biotrophic pathogen Blumeria graminis f. sp. hordei, respectively. These results indicate that GBP1 is involved in the establishment of symbiotic associations with beneficial fungi, a role that has potentially been appropriated by barley-adapted pathogens
