    • Head Tracking using a Textured Polygonal Model 

      Schodl, Arno; Haro, Antonio; Essa, Irfan A. (Georgia Institute of Technology, 1998)
      We describe the use of a three-dimensional textured model of the human head under perspective projection to track a person's face. The system is hand-initialized by projecting an image of a face onto the polygonal head ...
    • High Quality Image Warp Filters on Pyramids 

      Tumblin, John Erwin (Jack); Guenter, Brian K. (Georgia Institute of Technology, 1993)
      Directional filters applied to prefiltered imput image pyramids strike a good balance between fast computation and sharp, alias-free images, and are widely used for texture mapping and image warping. However, most published ...
    • How do we interact with an agent: A perspective from an undergraduate human factors class 

      McCrickard, D. Scott; Cheng, May Wing-Sze (Georgia Institute of Technology, 1998)
      Undergraduate human factors classes explore guidelines for the design of user interfaces. However, these guidelines may not apply when dealing with agents, which run constantly without explicit direction from a user. An ...
    • Ictus: A User-Centered System of Score Study for Semi-Novice Conductors 

      Mitchell, Amy; Voida, Stephen; Paradise, Jessica; Martin, Chris C.; Mynatt, Elizabeth D. (Georgia Institute of Technology, 2000)
      Ictus supports the study and preparation of musical scores by semi-novice conductors. It does so by representing the complex analytical processes in which professional conductors routinely engage. Through iterative design ...
    • Image-Driven Mesh Optimization 

      Lindstrom, Peter; Turk, Greg (Georgia Institute of Technology, 2000)
      We describe a method of improving the appearance of a low vertex count mesh in a manner that is guided by rendered images of the original, detailed mesh. This approach is motivated by the fact that greedy simplification ...
    • Image-Driven Simplification 

      Lindstrom, Peter; Turk, Greg (Georgia Institute of Technology, 1999)
      We introduce the notion of image-driven simplification, a framework that uses images to decide which portions of a model to simplify. This is a departure from approaches that make polygonal simplification decisions based ...
    • Implant Sprays: Compression of Progressive Tetrahedral Mesh Connectivity 

      Pajarola, Renato B.; Rossignac, Jaroslaw R.; Szymczak, Andrzej (Georgia Institute of Technology, 1999)
      Irregular tetrahedral meshes, which are popular in many engineering and scientific applications, often contain a large number of vertices. A mesh of V vertices and T tetrahedra requires 48-V bits or less to store the ...
    • In Search of: Reliable Usage Data on the World Wide Web 

      Pitkow, James Edward (Georgia Institute of Technology, 1997)
      The WWW is currently the hottest testbed for future interactive digital systems. While much is understood technically about how the WWW functions, substantially less is known about how this technology is used collectively ...
    • Individual User Interfaces and Model-based User Interface Software Tools 

      Schlungbaum, Egbert (Georgia Institute of Technology, 1996)
      Currently, most of model-based user interface software tools use task, application, and presentation models to generate the running user interface. The point of this paper is to use an additional user model to create ...
    • Inference Bear: Inferring Behavior from Before and After Snapshots 

      Frank, Martin Robert; Foley, James D. (Georgia Institute of Technology, 1994)
      We present Inference Bear (Inference Based On Before And After Snapshots) which lets users build functional graphical user interfaces by demonstration. Inference Bear is the first Programming By Demonstration system based ...
    • Information Awareness on the Desktop: A Case Study 

      McCrickard, D. Scott (Georgia Institute of Technology, 1997)
      In the future, the amount of online information will increase as more people use the Internet for a growing number of activities. Staying updated on the status of important information requires a tool that will monitor ...
    • The Information Mural: A Technique for Displaying and Navigating Large Information Spaces 

      Jerding, Dean Frederick; Stasko, John T. (Georgia Institute of Technology, 1997)
      Information visualizations must allow users to browse information spaces and focus quickly on items of interest. Being able to see some representation of the entire information space provides an initial gestalt overview ...
    • The Information Mural: Increasing Information Bandwidth in Visualizations 

      Jerding, Dean Frederick; Stasko, John T. (Georgia Institute of Technology, 1996)
      Information visualizations must allow users to browse information spaces and focus quickly on items of interest. Being able to see some representation of the entire information space provides an initial gestalt overview ...
    • inSpace: Co-Designing the Physical and Digital Environment to Support Workplace Collaboration 

      Voida, Stephen; McKeon, Matt; Le Dantec, Christopher; Forslund, C.; Verma, Puja; McMillan, B.; Bunde-Pedersen, J.; Edwards, Keith; Mynatt, Elizabeth D.; Mazalek, Ali (Georgia Institute of Technology, 2008)
      In this paper, we unpack three themes for the multidisciplinary codesign of a physical and digital meeting space environment in supporting collaboration: that social practices should dictate design, the importance ...
