      Wartell, Zachary Justin; Ribarsky, William; Hodges, Larry F. (Georgia Institute of Technology, 1999)
      Stereoscopic display is a fundamental part of virtual reality HMD systems and HTD (head-tracked display) systems such as the virtual workbench and the CAVE. A common practice in stereoscopic systems is deliberate incorrect ...
    • Ball-map: Homeomorphism Between Compatible Surfaces 

      Chazal, Frederic; Lieutier, Andre; Rossignac, Jaroslaw R.; Whited, Brian (Georgia Institute of Technology, 2006)
      We introduce the ball-map, BM [subscript S],[subscript T], between two manifolds, S and T. It maps each point x of S to a point x = BM[subscript S],[subscript T](x) of T. Its inverse is BM[subscript T],[subscript S]. We ...
    • Basic principles of stereographic software development 

      Hodges, Larry F. (Georgia Institute of Technology, 1991)
      Generation of images for a time-multiplexed stereoscopic display environment is not a straightforward extension of image generation in a perspective graphics environment. There are several factors that must be taken into ...
    • A Bayesian View of Boosting and Its Extension 

      Bobick, Aaron F.; Essa, Irfan A.; Shi, Yifan (Georgia Institute of Technology, 2005)
      In this paper, we provide a Bayesian perspective of boosting framework, which we refer to as Bayesian Integration. Through this perspective, we prove the standard ADABOOST is a special case of the naive Bayesian tree with ...

      Xiao, Jun; Catrambone, Richard; Stasko, John T. (Georgia Institute of Technology, 2003)
      This research examined the ability of an anthropomorphic interface assistant to help people learn and use an unfamiliar text-editing tool, with a specific focus on assessing proactive a ssistant behavior. Participants in ...
    • Bender: A Virtual Ribbon for Deforming 3D Shapes in Biomedical and Styling Applications 

      Llamas, Ignacio; Powell, Alexander; Rossignac, Jaroslaw R.; Shaw, Christopher D. (Georgia Institute of Technology, 2004)
      In contrast to machined mechanical parts, the 3D shapes encountered in biomedical or styling applications contain many tubular parts, protrusions, engravings, embossings, folds, and smooth bends. It is difficult to design ...
    • Between Dinner and Children's Bedtime: Predicting and Justifying Routines in the Home 

      Nagel, Kristine Susanne; Hudson, James M.; Abowd, Gregory D. (Georgia Institute of Technology, 2005)
      Much previous research in availability, whether in the office or in the home, has developed linear regression models to help predict appropriate times for interruption. Although these models work well, they tend to be ...
    • The Beware Home: A Contextually Aware Haunted House 

      Kidd, Cory D.; Starner, Thad; Gandy, Maribeth; Quay, A. M. (Andrew M.) (Georgia Institute of Technology, 2000)
      In the Broadband Institute Residential Laboratory, we are exploring interaction techniques for a contextually aware home [1]. Here we describe several recent projects that were adapted to create a haunted house for ...
    • Beyond the Scrollbar: An Evolution and Evaluation of Alternative List Navigation Techniques 

      McCrickard, D. Scott; Catrambone, Richard (Georgia Institute of Technology, 1997)
      List navigation devices such as scrollbars provide a simple way to browse and find items in a list, but they typically do not communicate information about individual list entries. This paper presents two alternative ...
    • Biasing Behavioral Activation with Intent 

      Ulam, Patrick D.; Arkin, Ronald C. (Georgia Institute of Technology, 2006)
      Deliberate control of an entertainment robot presents a special problem in balancing the requirement for intentional behavior with the existing mechanisms for autonomous action selection. We propose that the intentional ...
    • Biologically-Inspired Innovation in Engineering Design: a Cognitive Study 

      Vattam, Swaroop; Helms, Michael E.; Goel, Ashok K. (Georgia Institute of Technology, 2007)
      Biologically-inspired design uses analogous biological phenomena to develop solutions for engineering problems. Understanding, learning and practicing this approach to design is challenging because biologists and engineers ...
    • Blist: A Boolean List Formulation of CSG Trees 

      Rossignac, Jaroslaw R. (Georgia Institute of Technology, 1999)
      Set membership classification algorithms visit nodes of a CSG tree through a recursive divide-and-conquer process, which stores intermediate results in a stack, whose depth equals the height, H, of the tree. During this ...
    • Blowing Bubbles for the Multi-Scale Analysis and Decomposition of Triangle-Meshes 

      Mortara, Michela; Patane, Giuseppe; Spagnuolo, Michela; Falcidieno, B. (Bianca); Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2003)
      Tools for the automatic decomposition of a surface into shape features will facilitate the editing, matching, texturing, morphing, compression, and simplification of 3D shapes. Different features, such as flats, limbs, ...
    • Boosted Bayesian Network Classifiers 

      Jing, Yushi; Pavlovic, Vladimir; Rehg, James M. (Georgia Institute of Technology, 2005)
      The use of Bayesian networks for classification problems has received significant recent attention. Although computationally efficient, the standard maximum likelihood learning method tends to be suboptimal due to the ...
    • Boundary of the Volume Swept By a Free-form Solid in Screw Motion 

      Rossignac, Jaroslaw R.; Kim, J. J.; Song, S. C.; Suh, K. C.; Joung, C. B. (Georgia Institute of Technology, 2006)
      The swept volume of a moving solid provides an excellent aid for path and accessibility planning in robotics and for simulating various manufacturing operations. To compute the boundary of the swept volume, we approximate ...
