    • A System for Finding Frequently Lost Objects in the Home 

      Orr, Robert J.; Raymond, Ronald; Berman, Joshua; Seay, A. Fleming (Georgia Institute of Technology, 1999)
      In this paper, we describe a system for finding frequently lost personal objects -- such as wallets, cell phones and sunglasses -- in the home of the future. We are building a system to handle this task, and have prototyped ...
    • A System for Tracking and Recognizing Multiple People with Multiple Camera 

      Stillman, Scott T.; Tanawongsuwan, Rawesak; Essa, Irfan A. (Georgia Institute of Technology, 1998)
      In this paper we present a robust real-time method for tracking and recognizing multiple people with multiple cameras. Our method uses both static and Pan-Tilt-Zoom (PTZ) cameras to provide visual attention. The PTZ camera ...
    • TACTICS for User Interface Design: Coupling the Compositional and Transformational Approach 

      Kovacevic, Srdjan (Georgia Institute of Technology, 1993)
      The paper describes TACTICS, the model and a model-based tool capable of supporting a wide range of design decisions and providing assistance in the design process. The TACTICS tool automatically generates a user interface ...
    • Techniques for Low Cost Spatial Audio 

      Burgess, David A. (Georgia Institute of Technology, 1992)
      There are a variety of potential uses for interactive spatial sound in human-computer interfaces, but hardware costs have made most of these applications impractical. Recently, however, single-chip digital signal processors ...
    • Technology Trends Favor Thick Clients for User-Carried Wireless Devices 

      Starner, Thad (Georgia Institute of Technology, 2002)
      A thin client approach to mobile computing pushes as many services as possible on a remote server. However, as will be shown, technology trends indicate that an easy route to improving thin client functionality is to ...
    • Temporal Integration of Multiple Silhouette-Based Body-Part Hypotheses 

      Kwatra, Vivek; Bobick, Aaron F.; Johnson, Amos Y., Jr. (Georgia Institute of Technology, 2002)
      A method for temporally integrating appearance-based body-part labelling is presented. We begin by modifying the silhouette labelling method of "Ghose"; that system first determines which posture best describes the person ...
    • Ten Inch Pixels: Ambient Art for Remote Awareness 

      Mankoff, Jennifer C.; Rowan, James Thomas, Jr.; Mynatt, Elizabeth D.; McJunkin, Mark P. (Georgia Institute of Technology, 2001)
      We present an ambient display for supporting social connections between extended family members. The display, a digitally-controlled combination of oil on canvan and mechanical sculpture, consists of four, ten-by-ten inch ...
    • TetStreamer: Compressed Back-to-Front Transmission of Delaunay Tetrahedra Meshes 

      Bischoff, Urs; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2004)
      We use the shorts tet and tri for tetrahedron and triangle. TetStreamer encodes a Delaunay tet mesh in a back-to-front visibility order and streams it from a server to a client (volumetric visualizer). During decompression, ...
    • Thinking in Pictures as a Cognitive Account of Autism 

      Kunda, Maithilee; Goel, Ashok K. (Georgia Institute of Technology, 2010)
      We analyze the hypothesis that some individuals on the autism spectrum may use visual mental representations and processes to perform certain tasks that typically developing individuals perform verbally. We present a ...
    • Third-Person Navigation of Whole-Planet Terrain in a Head-tracked Stereoscopic Environment 

      Wartell, Zachary Justin; Ribarsky, William; Hodges, Larry F. (Georgia Institute of Technology, 1998)
      Navigation and interaction in stereoscopic virtual environments with head-tracking for very large data sets present several challenges beyond those encountered with smaller or monoscopic data sets. First, zooming by ...
    • Three-Dimensional Computation Visualization 

      Stasko, John T. (Georgia Institute of Technology, 1992)
      Systems supporting the visualization and animation of algorithms, programs, and computations have focused primarily on two-dimensional graphics to date. In this paper we identify the need for three-dimensional graphics in ...
    • Tidy Animations of Tree Algorithms 

      Stasko, John T.; Turner, Carlton Reid (Georgia Institute of Technology, 1992)
      In software visualization and algorithm animation it is important that advances in system technologies are accompanied by corresponding advances in animation presentations. In this paper we describe methods for animating ...
    • Tightening: Curvature-Limiting Morphological Simplification 

      Williams, Jason Daniel; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2004)
      Given a planar set S of arbitrary topology and a radius r, we show how to construct an r -tightening of S, which is a set whose boundary has a radius of curvature everywhere greater than or equal to r and which only differs ...
    • Time-Critical Visual Exploration of Scalably Large Data 

      Ribarsky, William; King, Davis; Gavrilovska, Ada; Van de Pol, Rogier (Georgia Institute of Technology, 1998)
      This paper discusses visualization and analysis issues as datasets grow towards very large sizes, and it develops an approach to attack them. Datasets of this size become exploration-dominant since the scientists who create ...
    • A Token-based Access Control Mechanism for Automated Capture and Access Systems in Ubiquitous Computing 

      Iachello, Giovanni; Abowd, Gregory D. (Georgia Institute of Technology, 2005)
      We discuss the problems related to access control in automated capture and access systems, which capture, store and retrieve information gathered through sensors in physical environments. We discuss several unique requirements ...
    • Tone Reproduction for Realistic Computer Generated Images 

      Tumblin, John Erwin (Jack); Rushmeier, Holly E. (Georgia Institute of Technology, 1991)
      Radiosity and other global illumination methods for image synthesis calculate the 'real world' radiance values of a scene instead of the display radiance values that will represent them. This causes 'display range' problems ...
    • Tone Reproduction for Realistic Computer Generated Images 

      Tumblin, John Erwin (Jack); Rushmeier, Holly E. (Georgia Institute of Technology, 1992)
      Radiosity and other global illumination methods for image synthesis calculate the 'real world' radiance values of a scene instead of the display radiance values that will represent them. Ad-hoc conversions cause serious ...
