    • Real Clock Time Animation Support for Developing Software Visualizations 

      Stasko, John T.; McCrickard, D. Scott (Georgia Institute of Technology, 1995)
      Developers building software visualizations must use a graphics library and user interface toolkit as an underlying support platform. Often, these support environments are large, difficult to learn, low-level, and lacking ...
    • Real-Time Audio Spatialization with Inexpensive Hardware 

      Burgess, David A. (Georgia Institute of Technology, 1992)
      There are a variety of potential uses for interactive spatial sound in human-machine interfaces, but tremendous computational costs have made most of these applications impractical. Recently, however, single-chip digital ...
    • Real-Time Visualization of Scalably Large Collections of Heterogeneous Objects 

      Davis, Douglass; Ribarsky, William; Jiang, Tian-Yue; Faust, Nick L. (Nickolas Lea); Ho, Sean (Georgia Institute of Technology, 1999)
      This paper presents results for real-time visualization of out-of-core collections of 3D objects. This is a significant extension of previous methods and shows the generality of hierarchical paging procedures applied both ...
    • Real-Time, Continuous Level of Detail Rendering of Height Fields 

      Lindstrom, Peter; Koller, David; Ribarsky, William; Hodges, Larry F.; Faust, Nick L. (Nickolas Lea); Turner, Gregory (Georgia Institute of Technology, 1996)
      We present an algorithm for real-time level of detail reduction and display of high-complexity polygonal surface data. The algorithm uses a compact and efficient regular grid representation, and employs a variable screen-space ...
    • Real-time, Photo-realistic, Physically Based Rendering of Fine Sacle Human Skin Structure 

      Haro, Antonio; Guenter, Brian K.; Essa, Irfan A. (Georgia Institute of Technology, 2001)
      Skin is noticeably bumpy in character, which is clearly visible in close-up shots in a film or game. Methods that rely on simple texture-mapping of faces lack such high frequency shape detail, which makes them look ...
    • The Real-World Wide Web Browser: An Interface for a Continuously Available, General Purpose, Spatialized Information Space 

      Kooper, Rob; MacIntyre, Blair (Georgia Institute of Technology, 2000)
      In this paper, we describe an augmented reality (AR) system that acts as continuously available interface to a spatialized information space based on the World Wide Web. We present the assumptions we make about the ...
    • Recognizing Sign Language from Brain Imaging 

      Mehta, Nishant A.; Starner, Thad; Jackson, Melody Moore; Babalola, Karolyn O.; James, George Andrew (Georgia Institute of Technology, 2009)
      The problem of classifying complex motor activities from brain imaging is relatively new territory within the fields of neuroscience and brain-computer interfaces. We report positive sign language classification results ...
    • Recognizing Workshop Activity Using Body Worn Microphones and Accelerometers 

      Atrash, Amin; Starner, Thad (Georgia Institute of Technology, 2003)
      Most gesture recognition systems analyze gestures intended for communication (e.g. sign language) or for command (e.g. navigation in a virtual world). We attempt instead to recognize gestures made in the course of performing ...
    • Reconstructing Surfaces by Volumetric Regularization 

      Dinh, Huong Quynh; Turk, Greg; Slabaugh, Gregory G. (Georgia Institute of Technology, 2000)
      We present a new method of surface reconstruction that generates smooth and seamless models from sparse, noisy, and non-uniform range data. Data acquisition techniques from computer vision, such as stereo range images and ...
