Designerly Tools

An assumption behind this paper is that research aimed at improving interaction design practice is not as successful as it could be. We will argue that one reason for this is that the understanding of what constitutes designerly tools is not enough recognized among those who propose new tools for interaction design. We define designerly tools as methods, tools, techniques, and approaches that support design activity in way that is appreciated by practicing interaction designers. Based on a two empirical studies, we have developed a framework and a way of studying designers and their tools. We discuss some insights about what characterizes designerly tools and what kind of implications these insights might have for the further development of tools aimed at supporting design practice.

FreeForm: An informal environment for interface prototyping

Best practice in interface design suggests that hand-drawn sketches are preferable at the early stages of the design process. This paper describes the FreeForm software which supports informal sketched interface design by acting as a Visual Basic Add-In. The Software utilises a digital whiteboard and pen input to support sketching and “running” of an informal prototype

Sketch-Based Interfaces to Support Collaborative Conceptual Design Learning

In order to gain a better understanding of online collaborative conceptual design processes this paper investigates how student designers make use of Lyceum, a shared virtual synchronous environment when engaged in conceptual design. The software enables users to talk to each other and share sketches when they are remotely located. The paper describes a novel methodology for observing and analysing collaborative design processes by adapting the concepts of grounded theory. Rather than concentrating on narrow aspects of the final artefacts, emerging 'themes' are generated that provide a broader picture of collaborative design process and context descriptions. Findings on the themes of 'grounding – mutual understanding' and 'support creativity' complement findings from other research, while important themes associated with 'near-synchrony' have not been emphasised in other research. From the study, a series of design recommendations are made for the development of tools to support online computer-supported collaborative work in design using a shared virtual environment

Support for participation in electronic paper prototyping

In this paper, we examine a range of tools for early prototyping of interactive systems that might be described as enabling 'electronic paper prototyping'. We then introduce Gabbeh, a prototype that we are developing to re-enable participatory design when using such tools. Paper-prototyping is an established approach to the creation of early prototypes in the participatory design of computer systems. Recent years have seen the rapid development of new interaction devices in which a display screen is combined with pen-based input to allow users to create sketches or hand-written notes in an interaction that is similar to writing with a pen on paper. Research with such devices has shown how this capability can be used to rapidly create simple prototypes of interactive systems such as websites. However, previous systems have not considered how end-users and other stakeholders could contribute to design dialogues around such prototypes.</p

Using an interactive whiteboard and a computer-programming tool to support the development of the key competencies in the New Zealand curriculum

Does children’s use of the software Scratch provide potential for the enhancement of key competencies as they work in pairs at the interactive whiteboard (IWB)? This article looks at how children using Scratch collaborated and managed their projects as they set about designing, constructing, testing and evaluating a game for others to play, a task that provided a sustained challenge over six weeks and beyond. The findings showed that the key competencies of participating, contributing, and relating to others were enhanced by the collaborative use of Scratch at the IWB, and that creative and conceptual thinking processes were sustained. Children became increasingly adept at using Scratch, and some children, previously thought to have poor social skills, began to articulate their understandings to others. While a guiding and scaffolding role was evident in teachers’ actions, close monitoring of group progress and direct input from teachers is required to keep the challenge high but achievable, and to extend children’s knowledge and thinking as they use Scratch at the IWB

From remembering to envisioning product use: an informal design technique

To be able to get insight in potential use experiences of design proposals, designers would ideally have continuous access to a diverse group of end-users who could give feedback. Since in practice this is not possible designers often have to rely on other sources to be able to reflect on the use issues of their design proposals. Previous research has shown that designers often apply informal techniques to reflect on use issues, in which personal knowledge and experience of previous projects serve as a frame of reference.. However, this knowledge often remains implicit. In this study we explore a technique in which members of a design team make all personal knowledge and assumptions about use in a certain product domain explicit. In this technique we distinguish remembering, imagining, experiencing and envisioning use. The information that is gathered in this way is captured in a matrix which structures use situation aspects and corresponding use issues. These issues concern user experience, usability as well as performance. In three workshops with different designers we explored the benefits and limitations of such a technique. Particularly iterating between remembering, imagining and experiencing worked very well to evoke experiences of the designer

Learning outcome dependency on contemporary ICT in the New Zealand middle school classroom

Often studies of children's technology use in the classroom is internally focused and small scale. This study attempts a globalised exploratory overview of an entire New Zealand middle school to understand the technology usages across a range of curriculum and learning outcomes. Observations of the use of technology in the classroom during eight different lessons were conducted followed by structured-open-ended interviews. From our classroom observations and through teacher interviews, we have been able to identify three levels of the dependency of learning outcome on contemporary-ICT

Lyceum: internet voice groupware for distance learning

This paper describes the design, implementation and deployment of Lyceum, a groupware system providing students and tutors with real time voice conferencing and visual workspace tools, over the standard internet. Lyceum uses a Java client/server architecture to tackle a formidable set of networking requirements: multi-way voice communication with synchronous shared displays, scalable to hundreds of simultaneous users, running over normal modem connections via unknown internet service providers, on home PCs. Additionally, the design had to support multiple courses with different requirements. We describe the interdisciplinary requirements analysis, and iterative design process, by which an academic course team was able to specify and evaluate prototypes. We present the systemís architecture, describe the technical successes and failures from Lyceumís first large scale deployment, and summarise its affordances for interaction and learning
