In pursuit of rigour and accountability in participatory design

The field of Participatory Design (PD) has greatly diversified and we see a broad spectrum of approaches and methodologies emerging. However, to foster its role in designing future interactive technologies, a discussion about accountability and rigour across this spectrum is needed. Rejecting the traditional, positivistic framework, we take inspiration from related fields such as Design Research and Action Research to develop interpretations of these concepts that are rooted in PD׳s own belief system. We argue that unlike in other fields, accountability and rigour are nuanced concepts that are delivered through debate, critique and reflection. A key prerequisite for having such debates is the availability of a language that allows designers, researchers and practitioners to construct solid arguments about the appropriateness of their stances, choices and judgements. To this end, we propose a “tool-to-think-with” that provides such a language by guiding designers, researchers and practitioners through a process of systematic reflection and critical analysis. The tool proposes four lenses to critically reflect on the nature of a PD effort: epistemology, values, stakeholders and outcomes. In a subsequent step, the coherence between the revealed features is analysed and shows whether they pull the project in the same direction or work against each other. Regardless of the flavour of PD, we argue that this coherence of features indicates the level of internal rigour of PD work and that the process of reflection and analysis provides the language to argue for it. We envision our tool to be useful at all stages of PD work: in the planning phase, as part of a reflective practice during the work, and as a means to construct knowledge and advance the field after the fact. We ground our theoretical discussions in a specific PD experience, the ECHOES project, to motivate the tool and to illustrate its workings

Development of the Lens Antenna Deployment Demonstration (LADD) shuttle-attached flight experiment

The primary objective of the LADD Program is to develop a technology demonstration test article that can be used for both ground and flight tests to demonstrate the structural and mechanical feasibility and reliability of the single-axis roll-out space based radar (SBR) approach. As designed, the LADD will essentially be a generic strucutural experiment which incorporates all critical technology elements of the operational satellite and is applicable to a number of future antenna systems. However, to fully determine its design integrity for meeting the lens flatness and constant geometry requirements in a zero g environment under extreme thermal conditions, the LADD must be space flight tested. By accurately surveying the structure under varying conditions the membrane tolerance-holding capabilities of the structure will be demonstrated. The flight test will provide data to verify analytical tools used to predict thermal and structural behavior. Most important, the experiment will provide an initial indication of structural damping in a zero g vacuum environment. The recently completed Solar Array Flight Experiment (SAFE) showed orbital damping greater than that experienced during ground testing. From the experience and the information obtained from LADD it is hoped that designs can be confidently extrapolated to operational satellites with apertures in the 20 m by 60 m size range

Auditory Display Design : An Investigation of a Design Pattern Approach

PhDThis thesis investigates the design of audio for feedback in human-technology interaction— auditory displays. Despite promising progress in research and the potential benefits, we currently see little impact of audio in everyday interfaces. Changing interaction paradigms, new contexts of use and inclusive design principles, however, increase the need for an efficient, non-visual means of conveying information. Motivated by these needs, this work describes the development and evaluation of a methodological design framework, aiming to enhance knowledge and skill transfer in auditory display design and to enable designers to build more efficient and compelling auditory solutions. The work starts by investigating the current practice in designing audio in the user interface. A survey amongst practitioners and researchers in the field and a literature study of research papers highlighted the need for a structured design approach. Building on these results, paco – pattern design in the context space has been developed, a framework providing methods to capture, apply and refine design knowledge through design patterns. A key element of paco, the context space, serves as the organising principle for patterns, artefacts and design problems and supports designers in conceptualising the design space. The evaluation of paco is the first comparative study of a design methodology in this area. Experts in auditory display design and novice designers participated in a series of experiments to determine the usefulness of the framework. The evaluation demonstrated that paco facilitates the transfer of design knowledge and skill between experts and novices as well as promoting reflection and recording of design rationale. Alongside these principle achievements, important insights have been gained about the design process which lay the foundations for future research into this subject area. This work contributes to the field of auditory display as it reflects on the current practice and proposes a means of supporting designers to communicate, reason about and build on each other’s work more efficiently. The broader field of human-computer interaction may also benefit from the availability of design guidance for exploiting the auditory modality to answer the challenges of future interaction design. Finally, with paco a generic methodology in the field of design patterns was proposed, potentially similarly beneficial to other designing disciplines

Micro-ethics for participatory design with marginalised children

Marginalised children are uniquely vulnerable within western societies. Conducting participatory design research with them comes with particular ethical challenges, some of which we illustrate in this paper. Through several examples across two different participatory design projects (one with autistic children, another with visually impaired children), we reflect on the often overlooked tensions on the level of micro-ethics. We argue we are often required to rely on multiple moral frames of references. We discuss issues that the immediate interaction between researchers and marginalised children in participatory projects can bring and offer an understanding of how micro-ethics manifest in these collaborations. We contribute to a theoretical exploration of ethical encounters based on empirical grounds, which can guide other researchers in their participatory endeavours

Lean transformation in aerospace assembly operations

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering; and, (M.B.A.)--Massachusetts Institute of Technology, Sloan School of Management; in conjunction with the Leaders for Manufacturing Program at MIT, 2007.Includes bibliographical references (p. 81-82).For the past two decades, virtually all manufacturing companies in the United States have adopted or are in the process of adopting lean manufacturing. Globalization has resulted in the increased availability of reliable, low cost sources putting greater pressures on traditional US manufacturing companies to reduce costs. The need to successfully transform to lean has only grown in importance in this new operating environment, resulting in renewed focus on such initiatives in the United States. This thesis discusses various approaches to lean manufacturing with reference to specific examples from both academia and industry. In particular, lean transformation efforts in Mitchell Engine Company's* Final Assembly Plant will be provided as a case study. Focus on the JP-3525 fan case assembly cell provides specific examples on how shop floor improvements, assembly cell redesign, and flow can improve process cycle time and decrease variability. The direct result of this work has been a 15% decrease in cycle time and a 100% decrease in variability in the JP-3525 fan case assembly cell. Finally, the role front-line supervisors play in change initiatives will be introduced, discussing the position from both management and labor perspectives. Based on past research, recommendations will be made on how to improve cell leader effectiveness, recognizing these changes require systemic change within the organization.by Douglas H.

Social communication between virtual characters and children with autism

Children with ASD have difficulty with social communication, particularly joint attention. Interaction in a virtual environment (VE) may be a means for both understanding these difficulties and addressing them. It is first necessary to discover how this population interacts with virtual characters, and whether they can follow joint attention cues in a VE. This paper describes a study in which 32 children with ASD used the ECHOES VE to assist a virtual character in selecting objects by following the character’s gaze and/or pointing. Both accuracy and reaction time data suggest that children were able to successfully complete the task, and qualitative data further suggests that most children perceived the character as an intentional being with relevant, mutually directed behaviour

Pattern Design in the Context Space A Methodological Framework for Auditory Display Design

Common practice in the design of auditory display is hardly ever based on any structured design methodology. This leaves audio being widely underused or used inappropriately and inefficiently. We analyse the current status of research in this context and develop requirements for a methodological framework for auditory display design. Based on these requirements, we have created a framework of methods to capture, transfer and apply design knowledge based on design patterns - paco ad. We present the context space as the organising principle to conceptualise the design space facilitating the matching of design knowledge with solutions and the workflow. Finally, we elaborate on how we intend to evaluate the framework and how it can be supported by tools

Vom künstlichen Leben zur Lebenskunst: Was die Ethik digitaler Bildung von ökologischer Verantwortung lernen kann

Während die Digitalisierung weithin für diverse Ersetzungsphänomene menschlicher Kompetenzen bis hin zur Schaffung von künstlichen Superintelligenzen steht, handelt es sich im Kern doch vor allem um eine neue Form von Umwelt, der wir in unserer Leiblichkeit gegenüberstehen und mit ihr verschmelzen. In diesem Sinne betrachten wir soziale Netze, Robotik und KI als Kulturtechniken des Menschen, die selbst zu kultürlichen Umweltfaktoren humanen Sozialverhaltens werden. Vor dem Hintergrund komplexer Wechselwirkungen zwischen Mensch, Technik und Gesellschaft diskutieren wir die Frage der Verantwortung als Bedingungserhaltung menschlichen Handelns, die sich auch als ein Gradmesser digitaler Infrastrukturen, Ökologie und Bildung zu erweisen hat. Auf dem Weg in eine gewollte Zukunft plädieren wir für eine Ethik der Lebenskunst und Klugheit im Umgang mit natürlichen wie kultürlichen Umwelten, um schlussendlich soziale Innovation in Zeiten umfassender Digitalisierungsprozesse zu leben.While the Digital Transformation is widely perceived as a paradigm for replacing various human competencies up to the creation of an artificial superintelligence, in fact it represents a new form of environment to be encountered through human embodiment. Hence, we consider social networks, robotics and AI as cultural techniques that evolve into environmental factors of human social behavior. In this context of complex interdependencies between human, technology and society, we discuss the issue of responsibility as a matter of preserving the essential conditions for human agency, which at the same time serves as key indicator for digital infrastructures, ecology and education. On our way into technological futures which are truly desired we opt for ethics as a way of prudent living with and within natural and cultural environments in order to enable social innovation in a time of comprehensive digitization processes
