    • Using Animation to Design, Document and Trace Object-Oriented Systems 

      Shilling, John J.; Stasko, John T. (Georgia Institute of Technology, 1992)
      Current diagramming techniques for the development and documentation of object-oriented designs largely emphasize capturing relationships among classes. Such techniques cannot capture full designs because the static nature ...
    • Using Animations to Learn about Algorithms: An Ethnographic Case Study 

      Kehoe, Colleen Mary; Stasko, John T. (Georgia Institute of Technology, 1996)
      A number of studies have found that using animation for explaining dynamic systems had less beneficial effects on learning than hoped. Those results come as a surprise to many instructors and students in computer science ...
    • Using Glyphmaker to Create Customized Visualizations of Complex Data 

      Ribarsky, William; Ayers, Eric Z.; Mukherjea, Sougata (Georgia Institute of Technology, 1993)
      Glyphmaker is a general approach to data visualization/analysis that allows users to easily build customized representations of multivariate data and then gives them interactive tools to explore the patterns in and relations ...
    • Using Graphic History in Browsing the World Wide Web 

      Ayers, Eric Z.; Stasko, John T. (Georgia Institute of Technology, 1995)
      Users of hypertext systems often find themselves eagerly following hypertext links deeper and deeper into a hypertext web, only to find themselves "lost" and unable find their way back to previously visited pages. As ...
    • Using In-Home Power Lines to Extend the Range of Low-Power Wireless Devices 

      Stuntebeck, Erich P.; Robertson, Thomas; Abowd, Gregory D.; Patel, Shwetak N. (Georgia Institute of Technology, 2009)
      This work demonstrates the feasibility of using existing in-home electrical wiring to extend the operational range of certain wireless devices. Specifically, a wireless keyboard operating at 27 MHz, which has an operational ...
    • Using Sound Source Localization to Monitor and Infer Activities in the Home 

      Bian, Xuehai; Abowd, Gregory D.; Rehg, James Matthew (Georgia Institute of Technology, 2004)
      Recent research in ubiquitous computing has focused both on how to infer human activity from a variety of signals sensed in the environment as well as how to use that information to support interactions. In this paper, we ...
    • Using Squeak for Teaching User Interface Software 

      Guzdial, Mark (Georgia Institute of Technology, 2000)
      Squeak is a new programming language based on an old one that skipped some 15 years of development. Squeak is highly cross-platform, running on Windows, Macintosh, Linux, BeOS, and Windows CE devices (among others) ...
    • Using Student-Built Algorithm Animations as a Learning Aid 

      Stasko, John T. (Georgia Institute of Technology, 1996)
      The typical application of algorithm animation to assist instruction involves students viewing already prepared animations. An alternative strategy is to have the students themselves construct animations of algorithms. The ...
    • Using Texture Maps to Correct for Optical Distortion in Head-Mounted Displays 

      Watson, Benjamin A. (Benjamin Allen); Hodges, Larry F. (Georgia Institute of Technology, 1995)
      This paper describes a fast method of correcting for optical distortion in head-mounted displays (HMDs). Since the distorted display surface in an HMD is not rectilinear, the shape and location of the graphics window used ...
    • Using the Web as a Survey Tool: Results from the Second WWW User Survey 

      Pitkow, James Edward; Recker, Mimi (Georgia Institute of Technology, 1994)
      This paper presents the initial results from the second World Wide Web User Survey, which was advertised and made available to the Web user population for 38 days during October and November 1994. The survey is built on ...
    • Using Visualization to Foster Object-Oriented Program Understanding 

      Jerding, Dean Frederick; Stasko, John T. (Georgia Institute of Technology, 1994)
      Software development and maintenance tasks rely on and can benefit from an increased level of program understanding. Object-oriented programming languages provide features which facilitate software maintenance, yet the ...
    • Variational Implicit Surfaces 

      Turk, Greg; O'Brien, James F. (Georgia Institute of Technology, 1999)
      We introduce a new method of creating smooth implicit surfaces of arbitrary manifold topology. These surfaces are described by specifying locations in 3D through which the surface should pass, and also identifying locations ...
    • A Variational inference method for Switching Linear Dynamic Systems 

      Oh, Sang Min; Ranganathan, Ananth; Rehg, James M.; Dellaert, Frank (Georgia Institute of Technology, 2005)
      This paper aims to present a structured variational inference algorithm for switching linear dynamical systems (SLDSs) which was initially introduced by Pavlovic and Rehg. Starting with the need for the variational approach, ...
    • Vector Field Design on Surfaces 

      Zhang, Eugene; Mischaikow, Konstantin Michael; Turk, Greg (Georgia Institute of Technology, 2004)
      Vector field design on surfaces is necessary for many graphics applications: example-based texture synthesis, non-photorealistic rendering, and fluid simulation. A vector field design system should allow a user to create ...
