ARCAA: a framework to analyse the artefact ecology in computer music performance

This paper presents ARCAA (Actors, Role, Context, Activity, Artefacts), a framework that supports designers in understanding the artefact ecology in the music performance scenario, in particular, allowing to frame the role of the different actors. The ARCAA framework is the result of the combination of two different areas of HCI: artefact ecology concept, and design framework for digital musical instruments. The model borrows three categories from MINUET an established design framework and rethinks them from an ecological perspective. In ARCAA, these three categories are used as three lenses to connect each human actor to her artefact ecology. Finally, the framework allows comparing how the various artefacts create connections among the different people involved. The second part of the paper describes a case study that shows a practical adoption of the framework

Enabling Polyvocality in Interactive Documentaries through ‘Structural Participation’

Recent innovations in online, social and interactive media have led to the emergence of new forms of documentary, such as interactive documentaries (‘i-Docs’), with qualities that lend themselves to more open and inclusive production structures. Still, little is known about the experience of making and/or participating-in these kinds of documentary. Our two-year in-the-wild study engaged a large community-of-interest in the production of an i-Doc to explore the ethically-desirable yet challenging aim of enabling multiple subjects to have agency and control over their representation in a documentary. Our study reveals insights into the experiences of participating in an i-Doc and highlights key sociotechnical challenges. We argue that new sociotechnical infrastructure is needed, that frames both ‘executory’ and ‘structural’ forms of participation as symbiotic elements of a co-design process

Volunteer-based IT Helpdesks as Ambiguous Quasi-Public Services:A Case Study from Two Nordic Countries

In this case study we take a Nordic perspective on the tension between increased digitalisation of public services and the insufficient support for citizens with limited digital literacy. Volunteer-based IT helpdesk services in public libraries have emerged as an attempt to address this tension. Drawing on examples of volunteering in public library-based IT helpdesk services in two Nordic countries, this paper considers the IT helpdesks as quasi-public services. Based on interviews, observations and workshops, we explore: the work of IT helpdesk volunteers, the characteristics of helpdesk services offered, and the implications of these services being offered by volunteers. The services offered are of acceptable quality to the users while the ambiguity and lack of institutional support is making the service fragile. In spite of the challenges of the quasi-public IT helpdesk service we also note how it offers a potential platform for the co-design and support of new public services.
