This paper proposes a novel interaction paradigm for multi-touch interfaces, that integrates both touch and near-touch interactions. The paper describes the hardware prototype that we have built, as well as the computer vision approach that we propose for real-time hand tracking and differentiation between near-touch and touch events. We also present a case study showing how near-touch and touch interactions can be successfully integrated in an information visualization application.

Wu, Fuqu and Tory, Melanie (2009): PhotoScope: visualizing spatiotemporal coverage of photos for construction management. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 1103-1112.
PhotoScope visualizes the spatiotemporal coverage of photos in a photo collection. It extends the standard photo browsing paradigm in two main ways: visualizing spatial coverage of photos, and indexing photos by a combination of spatial coverage, time, and content specifications. This approach enables users to browse and search space- and time-indexed photos more effectively. We designed PhotoScope specifically to address challenges in the construction management industry, where large photo collections are amassed to document project progress. These ideas may also apply to any photo collection that is spatially constrained and must be searched using spatial, temporal, and content criteria. We describe the design choices made when developing PhotoScope and the results of user evaluation.

Díaz, Javier, Hu, Keyun and Tory, Melanie (2009): An exploratory study of tag-based visual interfaces for searching folksonomies. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 410-417.
Aesthetic features such as animation, 3D interaction, and visual metaphors are becoming commonplace in multimedia search interfaces. However, it is unclear which attributes are needed to encourage people to use these interfaces on an ongoing basis. To design a visual interface that will elicit continual use, we first need to establish a better understanding of users' goals and strategies, in order to determine which features are critical to support those tasks. This paper reports on an exploratory study of individuals engaging with five different image and video search interfaces. Our study helped us to understand users' experiences with a variety of features and design elements, as well as categorize their common search tasks and strategies. We identified four distinct types of search: Search Known Objects + Known Keywords, Search Known Objects + Unknown Keywords, Search Unknown Objects + Known Keywords, and Search Unknown Objects + Unknown Keywords. We also identified common strategies used to accomplish each of these search types. Our findings suggest that search interfaces should maximize screen space used for visual representations of the media, provide on-demand access to titles, tags, and other metadata, and provide contextual information about previously viewed items, current keywords, and alternate keyword possibilities.

We conducted an ethnographic field study examining how a building design team used representational artifacts to coordinate the design of building systems, structure, and architecture. The goals of this study were to characterize the different interactions meeting participants had with design artifacts, to identify bottlenecks in the design coordination process, and to develop design considerations for CSCW technology that will support in-person design coordination meetings of building design teams. We found that gesturing, navigation, annotation, and viewing were the four primary interactions meeting participants had with design artifacts. The form of the design information (2D vs. 3D, digital vs. physical) had minimal impact on gesture interactions, although navigation varied significantly with different representations of design information. Bottlenecks in the design process were observed when meeting participants attempted to navigate digital information, interact with wall displays, and access information individually and as a group. Based on our observations, we present some possible directions for future CSCW technologies, including new mechanisms for digital bookmarking, interacting with 2D and 3D design artifacts simultaneously, and enriched pointing techniques and pen functionality.

Designing collaborative interfaces for tabletops remains difficult because we do not fully understand how groups coordinate their actions when working collaboratively over tables. We present two observational studies of pairs completing independent and shared tasks that investigate collaborative coupling, or the manner in which collaborators are involved and occupied with each other's work. Our results indicate that individuals frequently and fluidly engage and disengage with group activity through several distinct, recognizable states with unique characteristics. We describe these states and explore the consequences of these states for tabletop interface design.

In: Dykstra-Erickson, Elizabeth and Tscheligi, Manfred (eds.) Proceedings of ACM CHI 2004 Conference on Human Factors in Computing Systems April 24-29, 2004, Vienna, Austria. pp. 73-80.
We compare 2D/3D combination displays to displays with 2D and 3D views alone. Combination displays we consider are: orientation icon (i.e., side-by-side), in-place methods (e.g., clip planes), and a new method called ExoVis. We specifically analyze performance differences (i.e., time and accuracy) for 3D orientation and relative position tasks. Empirical results show that 3D displays are effective for approximate navigation and relative positioning whereas 2D/3D combination displays (orientation icon and ExoVis) are useful for precise orientation and position tasks. Combination 2D/3D displays had as good or better performance as 2D displays. Clip planes were not effective for a 3D orientation task, but may be useful when only one slice is needed.

Computing devices within current work and play environments are relatively
static. As the number of 'networked' devices grows, and as people and their
devices become more dynamic, situations will commonly arise where users will
wish to use 'that device there' instead of navigating through traditional user
interface widgets such as lists. This paper describes a process for identifying
devices through a pointing gesture using custom tags and a custom stylus called
the gesturePen. Implementation details for this system are provided along with
qualitative and quantitative results from a formal user study. As ubiquitous
computing environments become more pervasive, people will rapidly switch their
focus between many computing devices. The results of our work demonstrate that
our gesturePen method can improve the user experience in ubiquitous
environments by facilitating significantly faster interactions between
