Typically viewed as competing design approaches, this paper illustrates how claims and personas can be used together in user interface design. Our combined approach is exemplified in the development of a notification system called NotiFly. We introduce the idea of claims-based personas as a design tool in a scenario-based approach. Following a discussion of NotiFly's development, we speculate on the theories that led to the system development and how they might impact HCI design process. Based on the findings encountered during the development of NotiFly, we present direction for future work to better systems like Notifly and notification systems in general. Copyright 2005 ACM.

The human-computerinteraction community has long been concerned with design. Terms such as 'creativity' and 'innovation' are frequently used when referring to the design process and in this paper we examine what creativity is with respect to design. Design is often a collaborative and, therefore, a social activity. We review the evolution of definitions of creativity, leading to our proposal of a unified definition, we present a theoretical account of why social creativity should in principle be more productive than individual creativity. We explain findings to the contrary in terms of three social influences on creativity and suggest that research in supporting design should focus on mitigating the effects of these social influences on the creativity of design teams.

Large high-resolution screens are becoming increasingly available and less expensive. This creates potential advantages for data visualization in that more dense data and fine details are viewable at once. Also, less navigation may be needed to see more data. However, little work has been done to determine the effectiveness of large highresolution displays, especially for basic low-level data visualization and navigation tasks. This paper describes an exploratory study on the effects of a large tiled display with a resolution of 3840x3072 as compared to two smaller displays (1560x2048 and 1280x1024). We conclude that, with finely detailed data, higher resolution displays that use physical navigation significantly outperform smaller displays that use pan and zoom navigation. Qualitatively, we also conclude that use of the larger display is less stressful and creates a better sense of confidence than the smaller displays.

Spatial collaboration is a specialized form of collaboration where the discussion relates to a physical space. This work investigates how to support distributed spatial collaboration activities. It presents a novel prototype that integrates both two-dimensional and three-dimensional representations. This collaborative software is examined in a qualitative study as a group virtually rearranges their lab furniture. The results describe the group's collaboration and their use of the combined representations. The findings highlight the usefulness of multiple representations and the need for additional features to support collaboration across representations. Copyright 2005 ACM.

As the field of human-computerinteraction matures, the need for proven, dependable engineering processes for interface development becomes apparent. Our continuing work in developing LINK-UP, an integrated design and reuse environment, suggests that a better understanding of the system image is key to the successful evaluation of design prototypes, and an aide in applying knowledge from the repository. This paper describes our ongoing work to enhance LINK-UP by developing and augmenting the system image to make it the central communication point between different stages of design and between different stakeholders. We report on a study of the new task flow that demonstrated the value of the system image within a broader design context. Overall, our findings indicate that the effective creation and use of knowledge repositories by novice HCI designers hinges on successful application of existing HCI design concepts within a practical integrated design environment.
