Storyboards offer designers a way to illustrate a narrative. Their creation can be enabled by tools supporting sketching or widget collections. As designers often incorporate previous ideas, we contribute the notion of blending the reappropriation of artifacts and their design tradeoffs with storyboarding. We present PIC-UP, a storyboarding tool su...

Artifacts can be used to inspire, guide, and create new designs. As approaches to design can range from focusing on inspiration to formalized reasoning, we seek to create and study artifacts that combine the use of images and rationale. In this paper, we contribute an understanding of the relationship between imagery and rationale through an invest...

As open source development has evolved, differentiation of roles and increased sophistication of collaborative processes has occurred. Recently, we described coordination issues in software development and an interactive visualization tool called the Social Health Overview (SHO) developed to address them (12). This paper presents an empirical evalu...

Storyboarding offers designers the opportunity to illustrate a visual narrative of use. Because designers often refer to past ideas, we argue that storyboards can be constructed by reusing shared ar tifacts. We present a study in which we explore how designers reuse artifacts c onsisting of images and rationale during storyboard construction. We fi...

Although designers seek to create designs that are novel, most are based in some part on previous work. However, formal methods for design rationale reuse are dismissed as too inhibiting to the creative process. In this chapter we argue for the reuse of rationale as a central activity in design, and explore how this can be used as part of the creat...

Decades of innovation in designing usable (and unusable) interfaces have resulted in a plethora of guidelines, usability engineering methods, and other design tools. However, novice developers often have difficulty selecting and utilizing theory-based design tools in a coherent design process. This work introduces an integrated design environment a...

Case studies contain valuable information about development records. They are, however, usually presented as textual documents. Here we begin an initial design for viewing case study data. A prototype for viewing case study data is created using information visualization techniques for the purpose of testing against existing techniques. The evaluat...

Collaborative storyboarding, with a focus on aggregating designers' expertise in the storyboarding process, offers the opportunity for a group of designers to make progress toward creating a visual narrative for a new interface or technology, but it requires the designers to work together to explore ideas, differentiate between options, and constru...

Although designers often try to create novel designs, many designs are based on previous work. In this paper we argue for the reuse of rationale, in the form of claims, as a central activity in design, and explore how this can be used to inspire creativity. We present a design activity in which images and claims are reused to create a storyboard an...

Artifacts-representations that express properties or captured information-can serve to inspire, represent, and manage the decisions made throughout the design process. This workshop will explore how these artifacts are created, used, and reused during design projects, toward understanding the overall impact on the larger discipline of design. Throu...

Reuse of HCI design knowledge could improve designs by leveraging previous research. With selection and integration core characteristics of reuse, search and sensemaking play large roles. Reuse of claims--reusable HCI design knowledge components--through a claims library, claims map, and claims relationships can support search and sensemaking.

Purpose – Decades of innovation in designing usable (and unusable) interfaces have resulted in a plethora of guidelines, usability methods, and other design tools. The purpose of this research is to develop ways for novice developers to effectively leverage and contribute to the large and growing body of usability knowledge and methods. Design/meth...

Storyboards and claims are two distinct artifacts used for system design in HCI. In this paper, we propose that these artifacts provide greater design value if they are used in combination. We first investigate the relative strengths and weaknesses of storyboards and claims in supporting design. Then, we present an exploratory study conducted to as...

Reusing HCI design knowledge shows potential in allowing practitioners to design based on previously identified concerns. A reuse approach is presented that is based on claims, design knowledge units encapsulating tradeoffs. Fundamental characteristics of reuse include abstraction, selection, specification, and integration. Claim relationships prov...

Keeping track of information from multiple sources leads to attention management challenges. We propose CaBN, a context-based notification system which alerts users of information from disparate sources such as e-mail and calendar events. The system determines the best way to deliver a notification by comparing the priorities of the incoming inform...

While the discipline of human-computer interaction is beginning to benefit from knowledge capture and reuse methods, lacking are effective tools to provide students with the breadth of knowledge and the importance of multidisciplinary exchanges that are vital to productive scientific disciplines. Our ongoing work on the LINK-UP knowledge management...

This paper describes the use of personas in a multi-disciplinary academic setting to identify collaborators and tailor an integrated design and knowledge reuse environment to their needs. Our environment, LINK-UP, is an emerging web-based system that aids designers in the creation of notification systems—systems that deliver information of interest...

Within the software development process, reuse at the requirements level has become an increasingly more compelling notion. Following a human-centric approach, this work focuses on both requirements and design solution reuse using a design knowledge repository. In recent years, many improvements have been made to increase reuse through design knowl...

Designers need guidance in tracing knowledge to support the iterative development of interactive software interfaces. Claims show promise in capturing design knowledge with concise descriptions of an artifact's psychological effects on users, but adoptions and modifications made during design processes result in new claims. The manner in which new...

This paper reports on current development of usability heuristics for large screen information exhibits. By basing the creation of such heuristics on real systems, and identifying real problems with those systems, our set is grounded and tailored to the specific application class. This process was done through scenario based design techniques invol...

Our goal is to develop a collaborative system that enables multiple users to share and develop information in the best possible manner. We produced BrainStorm, a system that facilitates the development of projects by letting users develop ideas. It consists of a large screen display running a server and clients working as notification systems, allo...

Design representations express the state of a design with respect to a followed design procedure. Scenario-Based Design (SBD) is an HCI usability engineering process that leverages claims, knowledge units encapsulating tradeoffs associated with design features. HCI students need to express the concepts and rationale in their interface design relate...

Collaborative storyboarding, an emerging area of research, entails having groups of users work together to produce a sequence of user-system interactions. We conducted a study in which groups of designers were asked to construct storyboards using predetermined components. Initial analysis of the study sessions shows the emergence of a model for col...

The design of interactive visual displays has long been a topic of interest for desktop computer systems, but the recent popularity of off-the-desktop systems encourages researchers to revisit many of the guidelines for display design that once were taken for granted. This paper describes issues encountered when transferring proved guidelines for t...

We propose an interactive learning environment for Human-Computer-Interaction design based on a new form of reusable design components organized in a knowledge repository . Our repository focuses on reusability and accessibility to share design knowledge among students. We evaluate how these reusable components impact student knowledge of the desig...
