    • Acting Deceptively: Providing Robots with the Capacity for Deception 

      Wagner, Alan R.; Arkin, Ronald C. (Georgia Institute of Technology, 2010)
      Deception is utilized by a variety of intelligent systems ranging from insects to human beings. It has been argued that the use of deception is an indicator of theory of mind (Cheney & Seyfarth, 2008) and of social ...
    • Adaptive Action Prompting: A Complementary Aid to Support Task-Oriented Interaction in Explorative User Interfaces 

      Kuehme, Thomas (Georgia Institute of Technology, 1993)
      Adaptive action prompting supports users by suggesting how to continue with the interaction. A small number of continuously updated action prompts are offered in addition to the regular menu interface of an application. ...
    • Adaptive Prompting 

      Kuehme, Thomas; Malinowski, Uwe; Foley, James D. (Georgia Institute of Technology, 1993)
      Adaptive prompting addresses problems with locating, referencing, and selecting interface items such as elements of directory hierarchies or menu and dialog box entries. By drawing the user's attention to the most appropriate ...
    • Advanced Auditory Menus 

      Yalla, Pavani; Walker, Bruce N. (Georgia Institute of Technology, 2007)
    • Advections with Significantly Reduced Dissipation and Diffusion 

      Kim, Byungmoon; Liu, Yingjie; Llamas, Ignacio; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2006)
      Back and Forth Error Compensation and Correction (BFECC) can be applied to reduce dissipation and diffusion in advection steps, such as velocity, smoke density, and image advections. It can be implemented trivially as a ...
    • Aggregation Bias and the Use of Regression in Evaluating Models of Human Performance 

      Walker, Neff; Catrambone, Richard (Georgia Institute of Technology, 1992)
      Regression analysis is increasingly being used to provide confirmatory evidence for models of human performance. The amount of information made available to judge these models is reduced because clearly established standards ...
    • Algorithms for Rendering Cubic Curves 

      Watson, Benjamin A. (Benjamin Allen); Hodges, Larry F. (Georgia Institute of Technology, 1992)
      We present two integer-only algorithms to be used in tandem for rendering cubic functions and parametric cubic curves with ratyional coefficients. We then show how to take advantage of curve shape to improve algorithm ...
    • An Analytic Comparison of Alpha-False Eye Separation, Image Scaling and Image Shifting in Stereoscopic Displays 

      Wartell, Zachary Justin; Hodges, Larry F.; Ribarsky, William (Georgia Institute of Technology, 2000)
      Stereoscopic display is a fundamental part of many virtual reality systems. Stereoscopic displays render two perspective views of a scene, each of which is seen by one eye of the user. Ideally the user's natural visual ...
    • The Analytic Distortion Induced by False-Eye Separation in Head-Tracked Stereoscopic Displays 

      Wartell, Zachary Justin; Hodges, Larry F.; Ribarsky, William (Georgia Institute of Technology, 1999)
      Stereoscopic display is a fundamental part of virtual reality systems such as the virtual workbench, the CAVE and HMD systems. A common practice in stereoscopic systems is deliberate incorrect modeling of user eye separation. ...
    • Analyzing and Visualizing Log Files: A Computational Science of Usability 

      Guzdial, Mark; Santos, Paulo J.; Badre, Albert; Hudson, Scott E.; Gray, Mark H. (Georgia Institute of Technology, 1994)
      Researchers in human-computer interactions know that software can easily be instrumented to create a trace of user events in the interface (which we call a log file) for later analysis. Using these data for studying usability ...
    • Analyzing Differences between Internet Information System Software Architectures 

      Abowd, Gregory D.; Pitkow, James Edward; Kazman, Rick (Georgia Institute of Technology, 1995)
      While the growth and variety of Internet information systems has been dramatic over the past five years, the methodical consideration of the differences between systems has not been emphasized. We present a particular ...
    • Animating Athletic Motion Planning By Example 

      Metoyer, Ronald A.; Hodgins, Jessica K. (Georgia Institute of Technology, 2000)
      Character animation is usually reserved for highly skilled animators and computer programmers because few of the available tools allow the novice or casual user to create compelling animated content. In this paper, we ...
    • Animating Human Athletics 

      Hodgins, Jessica K.; Wooten, Wayne L.; Brogan, David C.; O'Brien, James F. (Georgia Institute of Technology, 1995)
      This paper describes algorithms for the animation of men and women performing three dynamic athletic behaviors: running, bicycling, and vaulting. We animate these behaviors using control algorithms that cause a physically ...
    • Animating Sand, Mud, and Snow 

      Sumner, Robert W.; O'Brien, James F.; Hodgins, Jessica K. (Georgia Institute of Technology, 1998)
      Computer animations often lack the subtle environmental changes that should occur due to the actions of the characters. Squealing car tires usually leave no skid marks, airplanes rarely leave jet trails in the sky, and ...
    • Animating User Interfaces Using Animation Servers 

      Bharat, Krishna A.; Sukaviriya, Piyawadee (Noi) (Georgia Institute of Technology, 1993)
      Our approach to user interface animation involves simulating the interaction of a user with the interface by synthetically generating the input events that drive the session. The interaction is made explicit by displaying ...
    • 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 ...
