Improving co-design methods implies that we need to understand those methods, paying attention to not only the effect of method choices on design outcomes, but also how methods affect the people involved in co-design. In this article, we explore participants' experiences from a year-long participatory health service design project to develop ‘Better Outpatient Services for Older People’. The project followed a defined method called experience-based design (EBD), which represented the state of the art in participatory service design within the UK National Health Service. A sample of participants in the project took part in semi-structured interviews reflecting on their involvement in and their feelings about the project. Our findings suggest that the EBD method that we employed was successful in establishing positive working relationships among the different groups of stakeholders (staff, patients, carers, advocates and design researchers), although conflicts remained throughout the project. Participants' experiences highlighted issues of wider relevance in such participatory design: cost versus benefit, sense of project momentum, locus of control, and assumptions about how change takes place in a complex environment. We propose tactics for dealing with these issues that inform the future development of techniques in user-centred healthcare design.

We present a method for the situated discovery and articulation of issues at the intersection between the politics of place making and city planning. We describe the construction and use of designed tools, such as historical political archives; counterfactual maps; and cards to invite situated dialogue between the social and institutional practices and mechanisms that produce our cities. Grounded in an account of the political as vernacular and embodied, our analysis advance understandings on the politics of design, and on the complex interrelationship between places and political spaces. We outline how HCI can adopt methods and develop sensitivities to support democratic practices and publics envisioning their urban futures.

Actuating, dynamic materials offer substantial potential to enhance interior designs but there are currently few examples of how they might be utilised or impact user experiences. As part of a design-led exploration, we have prototyped (Wizard-of-Oz) an actuating, dining table runner (ActuEater1), and then developed a fully-interactive fabric version that both changes shape and colour (ActuEater2). Four in-situ deployments of 'ActuEaters' in different dinner settings and subsequent 'design crits' showed insights into how people perceive, interpret and interact with such slow-technology in interesting (and often unexpected) ways. The results of our 'ActuEating' studies provide evidence for how an actuating artefact can be simultaneously a resource for social engagement and an interactive decorative. In response, we explore design opportunities for situating novel interactive materials in everyday settings, taking the leap into a new generation of interactive spaces, and critically considering new aesthetic possibilities.

This paper reports a case study investigating the productive value of designers' creative practice within complex academic-industrial collaborations in which a designer's practice had a formative role. Adopting a pragmatic approach, collaborators' experiences of this project were reconstructed through interviews and ‘annotated timelines.’ Collaborators were found to value the designer's work in responding to their particular concerns whilst also opening up new possibilities. This paper discusses how such benefit is attributable to the ‘designerly thinking’ of skilled designers, shifting the focus of work from problem-solving to problematisation and enabling participants to collectively formulate concerns, roles, and potentialities. The paper concludes that designers' creative practice can enable collaborative projects to build upon and transcend participants' expertise and expectations through ‘creative exchange.

Engaging young people in participatory design can be challenging, particularly in health-related projects. In a study co-designing diabetes support and information services with teenagers, we found framing activities using popular culture was a useful strategy. Various cultural references helped us stage activities that were productive for the design process, and were engaging for our young participants (e.g. exploring practical implications through discussions in a ‘Dragons’ Den’). Some activities were more effective than others and the idea of language-games, which has been widely explored in participatory design, explains why our strategy was successful when there was a clear ‘family resemblance’ between the popular cultural references and certain essential stages of designing. However, attention is required in selecting appropriate cultural references if this strategy is adopted elsewhere, and design facilitators should focus first on devising accessible language-games, rather than expecting popular cultural references to provide complete solutions to the challenge of staging participatory design.
