    • Recognizing Workshop Activity Using Body Worn Microphones and Accelerometers 

      Atrash, Amin; Starner, Thad (Georgia Institute of Technology, 2003)
      Most gesture recognition systems analyze gestures intended for communication (e.g. sign language) or for command (e.g. navigation in a virtual world). We attempt instead to recognize gestures made in the course of performing ...
    • Reconstructing Surfaces by Volumetric Regularization 

      Dinh, Huong Quynh; Turk, Greg; Slabaugh, Gregory G. (Georgia Institute of Technology, 2000)
      We present a new method of surface reconstruction that generates smooth and seamless models from sparse, noisy, and non-uniform range data. Data acquisition techniques from computer vision, such as stereo range images and ...

      The Information, Robotics, and Intelligent Systems Division (IRIS) of the National Science Foundation commissioned a workshop to provide a set of recommendations concerning: 1. Opportunities for NSF's use of WWW for ...
    • Responsibility and Lethality for Unmanned Systems: Ethical Pre-mission Responsibility Advisement 

      Arkin, Ronald C.; Wagner, Alan R.; Duncan, Brittany (Georgia Institute of Technology, 2009)
      This paper provides an overview, rationale, design, and prototype implementation of a responsibility advisor for use in autonomous systems capable of lethal target engagement. The ramifications surrounding the potential ...
    • Results from the First World Wide Web Survey 

      Pitkow, James Edward; Recker, Mimi (Georgia Institute of Technology, 1994)
      The explosion of the World-Wide Web (WWW) across the Internet is staggering, both in terms of number of users and the amount of activity. However, to date, no reliable characterization exists of WWW users. In this paper, ...
    • Results from the Third WWW User Survey 

      Pitkow, James Edward; Kehoe, Colleen Mary (Georgia Institute of Technology, 1996)
      The tremendous success of the World Wide Web has led to an ever-increasing user base. Intuitively, one would expect this base to change over time as more people from different segments of the population become Web users ...
    • Rethinking the Evaluation of Algorithm Animations as Learning Aids: An Observational Study 

      Kehoe, Colleen Mary; Stasko, John T.; Taylor, Ashley (Georgia Institute of Technology, 1999)
      A number of prior studies have found that using animation to help teach algorithms had less beneficial effects on learning than hoped. Those results surprise many computer science instructors whose intuition leads them to ...
    • A Review of the Fundamental Effects of Multimedia Information Presentation on Learning 

      Najjar, Lawrence Joseph (Georgia Institute of Technology, 1995)
      This paper examines the question, "Does multimedia information presentation help people learn?" The paper begins by describing general learning theory and several specific theories more closely related to multimedia and ...
    • Revisiting and Validating a Model of Two-Thumb Text Entry 

      Clarkson, Edward C.; Lyons, Kenton Michael; Clawson, James; Starner, Thad (Georgia Institute of Technology, 2006)
      MacKenzie and Soukoreff have previously introduced a Fitts' Law--based performance model of expert two--thumb text entry on mini--QWERTY keyboards. In this work we validate the original model and update it to account for ...
    • The Right Tool at the Right Time -- Investigation of Freehand Drawing as an Interface to Knowledge Based Design Tools 

      Do, Ellen Yi-Luen (Georgia Institute of Technology, 1998)
      Designers use different symbols and configurations in their drawings to explore alternatives and to communicate with each other. For example, when thinking about spatial arrangements, they draw bubble diagrams; when thinking ...
    • Ringing Js refinements 

      Schaefer, Scott; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2007)
      Both the four-point and the uniform cubic B-spline refinement (i.e. subdivision) schemes double the number of vertices of a closed-loop polygonal curve jP and respectively produce sequences of vertices fk and bk. The Js ...
    • Robot Catching 

      Riley, Marcia; Atkeson, Christopher G. (Georgia Institute of Technology, 2000)
      Our focus is on creating interesting, ralistic behaviors for humanoid robots and virtual charaters. Among the methods we use to create human-like movements are a template-based approach, where example movements from humans ...
    • Robot Herds: Group Behaviors for Systems with Significant Dynamics 

      Hodgins, Jessica K.; Brogan, David C. (Georgia Institute of Technology, 1994)
      Birds, fish, and many other animals are able to move gracefully and efficiently as a herd, flock, or school. We would like to reproduce this behavior for herds of artificial creatures with significant dynamics. This paper ...
