Five different auditory displays were designed to aid blind users in finding objects in a virtual haptic 3d environment. Each auditory display was based on a different principle and incorporated different methods for representing spatial information. Results from an evaluation with seven visually impaired persons reveal to what extent these methods facilitate object localization in a virtual haptic 3d environment.

Over time, many people accumulate extensive email repositories that contain detailed information about their personal communication patterns and relationships. We present three visualizations that capture hierarchical, correlational, and temporal patterns present in user's email repositories. These patterns are difficult to discover using traditional interfaces and are valuable for navigation and reflection on social relationships and communication history. We interviewed users with diverse email habits and found that they were able to interpret these images and could find interesting features that were not evident to them through their standard email interfaces. The images also capture a wide range of variation in email practices. These results suggest that information visualizations of personal communications have value for end-users and analysts alike.

Nearly 50 years of empirical research has suggested that social influences have an inhibiting effect on creativity in collaborating groups such as design teams. This suggests that design teams may not be as creative as they could be, resulting in a negative impact on the design process. In this paper we investigate the effect of group composition on creativity in terms of divergent thinking, in order to determine how best to support the creative process in design and the development of design environments. We present some novel results about 'group think', showing that real groups foster refinement of ideas while nominal groups foster duplication of ideas. Copyright 2006 ACM.

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 provide the key to instantiating each of these traits within the claims reuse approach. A claims library is used implement a working model of the reuse process. Studies analyzing various components of this work validate existing efforts and provide impetus for future work. Copyright is held by the author/owner(s).
We present a novel approach to developing interfaces for multi-application dialogue systems. The targeted interfaces allow transparent switching between a large number of applications within one system. The approach, ...

In this paper we describe a novel approach for searching large data sets from a mobile phone. Existing interfaces for mobile search require keyword text entry and are not suited for browsing. Our alternative uses a hybrid model to de-emphasize tedious keyword entry in favor of iterative data filtering. We propose navigation and selection of hierarchical metadata (facet navigation), with incremental text entry to further narrow the results. We conducted a formative evaluation to understand the relative advantages of keyword entry versus facet navigation for both browse and search tasks on the phone. We found keyword entry to be more powerful when the name of the search target is known, while facet navigation is otherwise more effective and strongly preferred. Copyright 2006 ACM.

Through a study of field biology practices, we observed that biology fieldwork generates a wealth of heterogeneous information, requiring substantial labor to coordinate and distill. To manage this data, biologists leverage a diverse set of tools, organizing their effort in paper notebooks. These observations motivated ButterflyNet, a mobile capture and access system that integrates paper notes with digital photographs captured during field research. Through ButterflyNet, the activity of leafing through a notebook expands to browsing all associated digital photos. ButterflyNet also facilitates the transfer of captured content to spreadsheets, enabling biologists to share their work. A first-use study with 14 biologists found this system to offer rich data capture and transformation, in a manner felicitous with current practice. Copyright 2006 ACM.
