    • A Notation for the Visual Specification of Geometric Relations in Rule-Based User Interface Development Environments 

      Yeatts, Andrey K.; Hudson, Scott E. (Georgia Institute of Technology, 1993)
      This paper describes a new visual notation for specifying geometric relationships (for example, in a user interface presentation application). This notation is designed to provide a centerpiece for the visual specification ...
    • Object Spaces: Context Management for Human Activity Recognition 

      Moore, Darnell Janssen; Essa, Irfan A.; Hayes, M. H. (Monson H.) (Georgia Institute of Technology, 1998)
      In this paper, we propose a vision-based method for developing computer awareness of human activities. We present an object-oriented approach called ObjectSpaces that encapsulates context into scene objects. Objects provide ...
    • An Object-Oriented Architecture for the Simulation of Rigid-Body Kinematics 

      George, Geoff; Guenter, Brian K. (Georgia Institute of Technology, 1993)
      Kinematic simulation involves finding simultaneous zeros for a set of functions representing mechanical linkages which constrain the positions and orientations of a set of bodies. Evaluation of these functions, and of their ...
    • Of Bugs and Rats: Cyber-cleanliness, Cyber-squalor, and the Fantisies of Globalization 

      Harpold, Terry; Philip, Kavita (Georgia Institute of Technology, 1999)
      "KAMPALA, Oct 13, 1998 (Reuters) - Thousands of Ugandan students are unsure whether they have won university places after rats chewed through computer cables at the National Examination Board causing the system to crash, ...
    • Oil Painting Assistance Using Projected Light: Bridging the Gap Between Digital and Physical Art 

      Flagg, Matthew; Rehg, James M. (Georgia Institute of Technology, 2005)
      This paper presents a novel interactive system for guiding artists to paint using traditional media and tools. The enabling technology is a multi-projector display capable of controlling the appearance of an artist's canvas. ...
