    • PML: Representing Procedural Domains for Multimedia Presentations 

      Ram, Ashwin; Catrambone, Richard; Guzdial, Mark; Kehoe, Colleen Mary; McCrickard, D. Scott; Stasko, John T. (Georgia Institute of Technology, 1998)
      A central issue in the development of multimedia systems is the presentation of the information to the user of the system and how to best represent that information to the designer of the system. Typically, the designers ...
    • Precision Markup Modeling and Display in a Global Geospatial Environment 

      Wartell, Zachary Justin; Ribarsky, William; Faust, Nick L. (Nickolas Lea) (Georgia Institute of Technology, 2003)
      A data organization, scalable structure, and multiresolution visualization approach is described for precision markup modeling in a global geospatial environment. The global environment supports interactive visual navigation ...
    • Predicting Document Access in Large, Multimedia Repositories 

      Recker, Mimi; Pitkow, James Edward (Georgia Institute of Technology, 1994)
      Network-accessible multimedia databases, repositories, and libraries are proliferating at a rapid rate. A crucial problem for these repositories remains timely and appropriate document access. In this paper, we borrow a ...
    • Presence as the Defining Factor in a VR Application 

      Hodges, Larry F.; Kooper, Rob; Meyer, Thomas C.; De Graaff, Johannes J. (Hans); Rothbaum, Barbara O.; Opdyke, Dan; Williford, James S.; North, Max M. (Georgia Institute of Technology, 1994)
      The sense of presence that a user experiences in a virtual environment is perhaps the best known attribute of virtual reality. It is an appeal to this sense of presence that is used to distinguish virtual reality as something ...
    • Preserving Arc Length in Texture Mapping 

      Guenter, Brian K.; Robertson, Scott Lee (Georgia Institute of Technology, 1992)
      Conventional mappings from the texture plane to three-dimensional surfaces fail to maintain the arc length of the texture when it is mapped onto the surface. This leads to unnatural texture appearance. In addition, texture ...
    • Pressing: Smooth Isosurfaces with Flats from Binary Grids 

      Chica, Antonio; Williams, Jason Daniel; Andujar, Carlos; Brunet, Pere; Navazo, Isabel; Rossignac, Jaroslaw R.; Vinacua, A. (Georgia Institute of Technology, 2006)
      We propose an approach, called Pressing, for smoothing isosurfaces extracted from binary volumes while recovering their large planar regions (flats). Pressing uses global optimization to identify flats and constrained ...
    • Pressing: Smooth Isosurfaces with Flats from Binary Grids 

      Chica, Antonio; Williams, Jason; Andujar, Carlos; Brunet, Pere; Navazo, Isabel; Rossignac, Jaroslaw R.; Vinacua, Alvar (Georgia Institute of Technology, 2007)
      We explore the automatic recovery of solids from their binary volumetric discretizations. In particular, we propose an approach, called Pressing, for smoothing isosurfaces extracted from binary volumes while recovering ...
    • Privacy Mirrors: Understanding and Shaping Socio-technical Ubiquitous Computing Systems 

      Nguyen, David H.; Mynatt, Elizabeth D. (Georgia Institute of Technology, 2002)
      Privacy is a known issue in ubiquitous computing, exasperated by an oft-cited feature of ubiquitous computing - invisibility. Dangers of invisible computing are interfaces that do not give people the needed tools of awareness ...
    • Private Policies Examined: Fair Warning or Fair Game? 

      Jensen, Carlos; Potts, Colin (Georgia Institute of Technology, 2003)
      Posting privacy policies has become a popular practice with businesses as they seek to shield themselves from potential liability or regulation, as well as inform users about their privacy and rights. These policies are ...
    • A Probabilistic Approach to the Semantic Interpretation of Building Facades 

      Alegre, Fernando; Dellaert, Frank (Georgia Institute of Technology, 2004)
      We present a probabilistic image-based approach to the semantic interpretation of building facades. We are motivated by the 4D Atlanta project at Georgia Tech, which aims to create a system that takes a collection of ...
    • Probabilistic Topological Mapping for Mobile Robots using Urn Models 

      Ranganathan, Ananth; Dellaert, Frank (Georgia Institute of Technology, 2007)
      We present an application of Bayesian modeling and inference to topological mapping in robotics. This is a potentially difficult problem due to (a) the combinatorial nature of the state space, and (b) perceptual aliasing ...
    • Proceedings of the CHI 2000 Workshop on "The What, Who, Where, When, Why and How of Context-Awareness" 

      Morse, David R.; Dey, Anind K. (Georgia Institute of Technology, 2000)
      At the CHI 2000 Conference on Human Factors in Computing Systems (April 1-6, 2000), a workshop was held on "The What, Who, Where, When, and How of Context-Awareness". Context-awareness is widely thought to be an important ...
    • Proposal of a Model and Architecture for Handling Ambiguity in Recognition-Based Input 

      Mankoff, Jennifer C. (Georgia Institute of Technology, 1999)
      Recognition technologies are being used extensively in both the commercial and research world. But recognizers are still error-prone, and this results in performance problems and brittle dialogues, which are a barrier to ...
    • Providing Access to Graphical User Interfaces - Not Graphical Screens 

      Edwards, W. Keith; Mynatt, Elizabeth D.; Stockton, Kathryn (Georgia Institute of Technology, 1995)
      The 1990 paper "The Graphical User Interface: Crisis, Danger and Opportunity" summarized an overwhelming concern expressed by the blind community: a new type of visual interface threatened to erase the progress made by the ...
    • Providing High-Level Control and Expert Assistance in the User Interface Presentation Design 

      Kim, Won Chul; Foley, James D. (Georgia Institute of Technology, 1993)
      Current user interface builders provide only low-level assistance, because they have knowledge of neither the application nor the principles by which interface elements are combined effectively. We have developed a framework ...
    • Psychophysical Models in Image Synthesis 

      Geunter, Brian (Georgia Institute of Technology, 1992)
      It has long been known that the human visual system (HVS) is not a camera; the eye-retina-brain combination does not simply record a visual scene the way a movie camera or video camera does. Instead, the HVS processes the ...
    • Punctuated Simplification of Man-Made Objects 

      Jang, Justin; Wonka, Peter; Ribarsky, William; Shaw, Christopher D. (Georgia Institute of Technology, 2005)
      We present a simplification algorithm for manifold polygonal meshes of plane-dominant models. Models of this type are likely to appear in man-made environments. While traditional simplification algorithms focus on generality ...
    • A Pure Reasoning Engine for Programming by Demonstration 

      Frank, Martin Robert; Foley, James D. (Georgia Institute of Technology, 1994)
      We present an inference engine that can be used for creating Programming By Demonstration systems. The class of systems addressed are those which infer a state change description from examples of state. The engine can ...
