Manually reproducing bugs is time-consuming and tedious. Software maintainers routinely try to reproduce unconfirmed issues using incomplete or no informative bug reports. Consequently, while reproducing an issue, the maintainer must augment the report with information - such as a reliable sequence of descriptive steps to reproduce the bug - to aid developers with diagnosing the issue. This process encumbers issue resolution from the time the bug is entered in the issue tracking system until it is reproduced. This paper presents Crash Droid, an approach for automating the process of reproducing a bug by translating the call stack from a crash report into expressive steps to reproduce the bug and a kernel event trace that can be replayed on-demand. Crash Droid manages trace ability links between scenarios' natural language descriptions, method call traces, and kernel event traces. We evaluated Crash Droid on several open-source Android applications infected with errors. Given call stacks from crash reports, Crash Droid was able to generate expressive steps to reproduce the bugs and automatically replay the crashes. Moreover, users were able to confirm the crashes faster with Crash Droid than manually reproducing the bugs or using a stress-testing tool.

A deeper understanding of the interactions between people and artefacts that characterise creative activities could be valuable in designing the next generation of creativity support. This paper presents three perspectives on creative interaction that have emerged from four years of empirical and design research. We argue that creative interaction can be usefully viewed in terms of Productive Interaction - focused engagement on the development of a creative outcome, Structural Interaction - the development of the structures in which production occurs, and Longitudinal Interaction - the long-term development of resources and relationships that increase creative potential. An analysis of each perspective is described, along with the development of an exemplary prototype. The use of the perspectives as a basis for design is considered, including the influence of contextual factors on instances of creative activities.

This workshop brings together a community of researchers and practitioners to identify and develop the research agenda needed to enhance human interaction with increasingly powerful and independent intelligent systems e.g. sensors networks, autonomous systems, agents and robotic systems. These systems have applications in many domains including health, transport, environment, emergency situations and defense. Aspects of these systems give rise to properties found in loose federations, collaborations and dynamic coalitions. The research questions include awareness, joint working, decision-making, intentionality, coordination, task-allocation, and planning. The workshop brings together researchers from different disciplines to discuss and develop research and to provide a focus for interdisciplinary research in this area.

Creative tasks are performed within constraining structures. However, the exploration and development of these structures is central to the creative process. This paper summarizes research on the role of constraint in creative tasks, defines the role of constraint development in a model of the creative process, and classifies types of constraint in order to inform the design of environments for creative tasks. Links between constraint development and end user development in software environments are explored through analysis of the design and use of Music Builder, a prototype for the user development of musical instruments in a collaborative composition environment. Conclusions include the value of scaffolding as a metaphor in design, the utility of collaborative constraint development to negotiation, and coordination and the value of sharing structures in collaborative development.

This research explores links between constraint development in creative processes and end user development in environments for creative tasks. A process model describing the development of constraints in creative tasks is presented. To ground the research, support for the user development of musical instruments in a collaborative composition environment is developed, and the use of the system analysed. We find evidence that the development of tangible constraints in the interface has value to users, particularly in focusing collaborative ideation.

The design of tools for creative activities affects the creative processes and output of users. In this paper we consider how an understanding of creative interaction can inform the design of support tools in a creative domain, and where creative needs cross domain boundaries. Using observations of musical composers we analyse the theoretical approaches to understanding creativity and their use to HCI. Cycles of ideation and evaluation are suggested as atomic elements of creative interactions, with the representation of ideas a central activity for individual and collaborating composers. A model of collaborative composition was developed, along with an analysis of the representational types used in the domain. This led to the design and evaluation of a prototype Sonic Sketchpad for musical idea representation.

In this paper we propose an account of human/computer awareness for use in the (re)design of complex human/computer interaction, before empirically testing its utility. Specifically, having situated our work in the wider field of human/computer awareness research, we address the well-reported phenomenon of "situation awareness" breakdowns in the aviation domain. We assert the need for an explanatory and predictive model of the phenomenon if the frequency of such breakdowns is to be reduced and propose such a model. We then go on to investigate the utility of our model as a guide for design through the discussion of a recent experiment involving manipulations of an animated warning signal on a simulated cockpit control panel. Our results show initial support both for the model and for our assertion of its utility. We conclude that our composite view of awareness yields practical benefit in the design of human computer awareness support.

(1999). Introduction to This Special issue on Representations in Interactive Systems Development. Human–Computer Interaction: Vol. 14, Representations in Interactive Systems Development, pp. 1-7.

Participatory design (PD) and task analysis (TA) have each been widely promoted as amerlioratives to the problems of developing systems hat meet users' requirements. However, PD methods have tended to focus on design per se, rather than also promoting user-developer cooperation in upstream analysis activities. TA methods have promoted these upstream activities but largely failed to involve users directly in the analysis and modeling work. Hence, there is a need for a broader approach encourages user–developer cooperation throughout systems analysis and design activities. This article examines the support for user-developer interaction provided by representations of users' tasks and software designs in 2 real-world software development projects that followed a task-based cooperative development approach. In the course of the system deve1oprnenat work, h e representations were called on to serve a number of different purposes. Task model and paper prototype representations facilitated the development s f cowmen ground among h e members of the development team through h e provision of an external shared model of the object of the development activity and helped to delimit an interaction space in which the cooperative activity was conducted. Weaknesses of the representations as supports for cooperative development included users' reluctance physically to amend the representations and the very strength of common ground developed between the participants that was not explicitly represented in the external models.

The importance of an early and on-going focus on users in interactive system design is widely accepted. However, in practice, involving users poses many problems and requires designers to balance conflicting demands. Various factors can hinder or ease the involvement of users. This paper reports a case study involving the design of a bespoke application and gives a detailed account of the obstacles and facilitators to user involvement encountered during the design activity. The obstacles and facilitators are presented in terms of issues such as contacting and selecting users, motivating users, facilitating and mediating meetings and offering points of focus for user contributions. We report and contrast the views of various stakeholders in the design process, and supplement these with our own observations as non-participant observers. Finally, we discuss issues raised by the study and draw out a number of lessons for the CHI community.
