    • Animation Support in a User Interface Toolkit: Flexible, Robust, and Reusable Abstractions 

      Hudson, Scott E.; Stasko, John T. (Georgia Institute of Technology, 1993)
      Animation can be a very effective mechanism to convey information in visualization and user interface settings. However, integrating animated presentations into user interfaces has typically been a difficult task since, ...
    • Anisotropies in Stereo Depth Thresholds of Spatial Patterns and the Stereo Aperture Problem 

      Davis, Elizabeth Thorpe; King, Robert A.; Guenter, Brian K.; Anoskey, Alana (Georgia Institute of Technology, 1992)
      Does a pattern's orientation affect stereoacuity? Do vertical disparities play a role in stereopsis? Furthermore, is retinal disparity encoded by changes in spatial position or spatial phase? The latter implies a "stereo ...
    • Anthropomorphic Agents as a UI Paradigm: Experimental Findings and a Framework for Research 

      Catrambone, Richard; Stasko, John T.; Xiao, Jun (Georgia Institute of Technology, 2002)
      Research on anthropomorphic agent interfaces has produced widely divergent results. We suggest that this is due to insufficient consideration of key factors that influence the perception and effectiveness of agent-based ...
    • Anticipatory and Improvisational Robot via Recollection and Exploitation of Episodic Memories 

      Endo, Yoichiro (Georgia Institute of Technology, 2005)
      Previously, we have introduced an anticipatory robot that could generate a cognitive map while simultaneously localizing itself relative to it. Inspired by recent hippocampal researches, there, we demonstrated that the ...
    • Appearance-Preserving View-Dependent Visualization 

      Jang, Justin; Ribarsky, William; Shaw, Christopher D.; Wonka, Peter (Georgia Institute of Technology, 2003)
      In this paper, a new quadric-based view-dependent simplification scheme is presented. The scheme provides a method to connect mesh simplification controlled by a quadric error metric with a level-of-detail hierarchy that ...
    • Applying Dynamic Integration as a Software Infrastructure for Context-Aware Computing 

      Abowd, Gregory D.; Dey, Anind K.; Wood, Andrew (Georgia Institute of Technology, 1997)
      Much of the software engineering literature examines techniques and practices that help us to build systems that we have been building for many years already. While there is merit in seeking ways to raise the floor of ...
    • Applying Heuristic Evaluation to Human-Robot Interaction Systems 

      Clarkson, Edward C.; Arkin, Ronald C. (Georgia Institute of Technology, 2006)
      Though attention to evaluating human-robot interfaces has increased in recent years, there are relatively few reports of using evaluation tools during the development of human-robot interaction (HRI) systems to gauge and ...
    • Applying Program Visualization Techniques to Aid Parallel and Distributed Program Development 

      Stasko, John T.; Appelbe, William F.; Kraemer, Eileen T. (Georgia Institute of Technology, 1991)
      Parallel and distributed programming is intrinsically more difficult than sequential programming, yet few effective tools or methodologies have been developed to help programmers understand the behavior of their parallel ...
    • An Architecture for Spatial Audio Servers 

      Burgess, David A.; Verlinden, Jouke C. (Georgia Institute of Technology, 1993)
      Before spatial sound can be useful in large software systems, there must be a sufficient application programmer's interface (API) for the control of the spatial audio system and for the management of finite audio processing ...
    • An Architecture for Transforming Graphical Interfaces 

      Edwards, W. Keith; Mynatt, Elizabeth D. (Georgia Institute of Technology, 1995)
      While graphical user interfaces have gained much popularity in recent years, there are situations when the need to use existing applications in a nonvisual modality is clear. Examples of such situations include the use of ...
    • An Architecture to Support Context-Aware Applications 

      Dey, Anind K.; Salber, Daniel; Futakawa, Masayasu; Abowd, Gregory D. (Georgia Institute of Technology, 1999)
      Context is an important, yet poorly utilized source of information in interactive computing. It is difficult to use because, unlike other forms of user input, there is not common, reusable way to handle context. Most ...
    • Artistically Conveying Peripheral Information with the InfoCanvas 

      Miller, Todd; Stasko, John T. (Georgia Institute of Technology, 2002)
      The Internet and World Wide Web have made a tremendous amount of information available to people today. Taking advantage of and managing this information, however, is becoming increasingly challenging due to its volume and ...
    • Assessing Health Games in Secondary Schools: An Investigation of the American Horsepower Challenge 2009-2010 

      Eiríksdóttir, Elsa; Xu, Yan; Miller, Andrew; Poole, Erika; Catrambone, Richard; Kestranek, Dan; Mynatt, Elizabeth D. (Georgia Institute of Technology, 2011-07)
      We present detailed findings from our study of a long-term multi-site physical activity pervasive game for US middle school children: The American Horsepower Challenge. In this technical report, we concentrate on the ...
    • Assessing Program Visualization Systems as Instructional Aids 

      Badre, Albert; Beranek, Margaret; Morris, John Morgan; Stasko, John T. (Georgia Institute of Technology, 1991)
      Recently, program visualization systems have received much attention as learning tools and as software understanding aids. How to evaluate these systems, however, is an open and unexplored area. In order to determine what ...
    • Audience in Computer Learning: A Constructionist Interpretation 

      Hayes, Gillian Rachael; Piper, Anne Marie; Amar, Robert Anthony; Bevis, Korin J.; Newstetter, Wendy C.; Bruckman, Amy S. (Georgia Institute of Technology, 2004)
      Adolescents often anticipate the reactions of other people in social situations. We believe this construction of imaginary audiences serves as a stimulant to youth engagement in activities and their abilities to become ...
    • AudioExplorer: Multiple Linked Representations for Convergence 

      Rick, Jochen Friedolin (Georgia Institute of Technology, 2001)
      The problem of convergence is an important one for designing collaborative-learning environments. Ideally, learning environments can allow novices to work together to achieve convergence of correct understanding, without ...
    • Auditory Presentation of Graphical User Interfaces 

      Mynatt, Elizabeth D. (Georgia Institute of Technology, 1992)
