SUMMARYWe are investigating a novel user interface paradigm based on zooming, in which users are presented with a zooming view of a huge planar information surface. We have developed a system called Pad++ to explore this approach. † The implementation of Pad++ is related to real-time 3D graphics systems and to 2D windowing systems. However, the zooming nature of Pad++ requires new approaches to rendering, screen management, and spatial indexing. In this paper, we describe the design and implementation of the Pad++ engine, focusing in particular on rendering and data structure issues. Our goal is to present useful techniques that can be adopted in other real-time graphical systems, and also to discuss how 2D zooming systems differ from other graphical systems.
The development and testing of systems to support users engaged in exploratory search activities (i.e., searches where the target may be undefined) is an challenge for the online search community. In this article we report on a workshop on exploratory search issues organized in conjunction with the University of Maryland Human-Computer Interaction Laboratory's Annual Symposium and Open House in June 2005. This workshop brought together researchers from the fields of Information Seeking (IS), Information Retrieval (IR), Human-Computer Interaction (HCI) and Information Visualization (IV) for a cross-disciplinary exploration of these and other issues. Although originally intended to focus on interfaces to support exploratory search the workshop blossomed into a rich discussion of not only interface issues, but also evaluation, the cognitive processes that underlie information exploration and research methods.
We established an interdisciplinmy, intergenemtional collaboration in the fidl of 1995, between the University of New Mexico's Computer Science Departmen4 the College of Fducatiou and local Albuquerque elementary school children.The goal of this reaeamh was to develop an expressive digital medium with an intuitive zooming to support a learning environment tbr children. In the _ of this eollaboratio~design methodologies that support a child's role in the development of new technologies WE explored. What follows is a summary of our iterative design experience, collaboration, and the results of the resuch to date.
In this paper, we describe Single Display Groupware, a software model that enables multiple users to work simultaneously at a single computer display. We discuss the collaborative benefits observed during a pilot study of the SDG application, KidPad.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
