      This paper reports ongoing experience with the design and everyday use of an electronic context-enabled in/out board. We designed this application as part of the development of a context toolkit and it proved a fruitful ...
    • Detecting and Tracking Eyes by Using their Physiological Properties, Dynamics and Appearance 

      Haro, Antonio; Flickner, Myron; Essa, Irfan A. (Georgia Institute of Technology, 1999)
      Reliable detection and tracking of eyes is an important requirement for attentive user interfaces. In this paper, we present a methodology for detecting eyes robustly in indoor environments in real-time. We exploit the ...
    • Determination of the Correct Eye Position for Viewing Perspective Images of 3D Scenes 

      Jang, Justin; Rossignac, Jaroslaw R. (Georgia Institute of Technology, 2001)

    • Developing Voice-only Applications in the Absence of Speech Recognition Technology 

      Dey, Anind K.; Catledge, Lara D.; Abowd, Gregory D.; Potts, Colin (Georgia Institute of Technology, 1997)
      In this paper, we describe an information access system with a voice-only interface. We outline a design process for generating guidelines for voice-only interaction in the absence of adequate speech recognition technology. ...
    • The Development of an Educational Digital Library for Human-Centered Computing 

      Clarkson, Edward C.; Day, Jason Allan; Foley, James D. (Georgia Institute of Technology, 2005)
      Digital libraries have great potential to improve the educational experience. There are a wide variety of such repositories, especially those that focus on specifically on education. However, a survey of existing work shows ...
    • DIAMOND: A Framework for Dividing Interfaces Across Multiple Opportunistically aNnexed Devices 

      Pierce, Jeffrey S.; Hutchings, Heather M. (Georgia Institute of Technology, 2005)
      Despite the increasing prevalence of physically proximate computing devices, current interfaces remain largely limited to single computing devices because of the prevailing assumption that interfaces can only draw on input ...
    • Direct Manipulation on the Virtual Workbench: Two Hands Aren't Always Better Than One 

      Seay, A. Fleming; Krum, David Michael; Hodges, Larry F.; Ribarsky, William (Georgia Institute of Technology, 2000)
      This paper reports on the investigation of the differential levels of effectiveness of various interaction techniques on a simple rotation and translation task on the virtual workbench. Manipulation time and number of ...
    • Dirichlet Process based Bayesian Partition Models for Robot Topological Mapping 

      Ranganathan, Ananth; Dellaert, Frank (Georgia Institute of Technology, 2004)
      Robotic mapping involves finding a solution to the correspondence problem. A general purpose solution to this problem is as yet unavailable due to the combinatorial nature of the state space. We present a framework for ...
    • Discount Learnability Evaluation 

      Santos, Paulo J.; Badre, Albert (Georgia Institute of Technology, 1995)
      Learnability evaluation has traditionally required expensive and time-consuming techniques. Practitioners have refrained from performing extended learnability evaluation due to its prohibitive costs. We propose a discount ...
    • Discovery Visualization and Visual Data Mining 

      Ribarsky, William; Katz, Jochen; Jiang, Frank; Holland, Aubrey (Georgia Institute of Technology, 1999)
      This paper describes discovery visualization, a new visual data mining approach that has as a key element the heightened awareness of the user by the machine. Discovery visualization promotes the concept of continuous ...
    • Distributed Mediation of Imperfectly Sensed Context in Aware Environments 

      Dey, Anind K.; Mankoff, Jennifer C.; Abowd, Gregory D. (Georgia Institute of Technology, 2000)
      Current context-aware services make the assumption that the context they are dealing with is correct. However, in reality, both sensed and interpreted context is often imperfect. In this paper, we describe an architecture ...
    • Distributed Multi-AUV Coordination in Naval Mine Countermeasure Missions 

      Sariel, Sanem; Balch, Tucker; Stack, Jason (Georgia Institute of Technology, 2006)
      In this paper, we evaluate performance of our coordination framework, for Naval Mine Countermeasure (MCM) missions on the ALWSE-MC simulator. Our coordination framework integrates a distributed task allocation scheme, ...
    • Do Algorithm Animations Aid Learning? 

      Byrne, Michael Dwyer; Catrambone, Richard; Stasko, John T. (Georgia Institute of Technology, 1996)
      Two experiments examined the general claim that animations can help students learn algorithms more effectively. Animations and instructions that explicitly required learners to predict the behavior of an algorithm were ...
    • Does Multimedia Information Help People Learn? 

      Najjar, Lawrence Joseph (Georgia Institute of Technology, 1995)
      Multimedia is being used increasingly to provide computer-based instruction. While people generally believe that multimedia information helps people learn better than "monomedia" information, empirical support for this ...
