      Lyons, Kenton Michael; Patel, Nirmal J.; Starner, Thad (Georgia Institute of Technology, 2002)
      KeyMenu is a keyboard based hierarchical menu system originally designed for use on a wearable computer. The menu uses a one to one mapping between buttons on the keyboard and menu items. The KeyMenu leverages off of the ...
    • Kids Telling Fables Through 3D Animation 

      Zagal, José Pablo; Piper, Anne Marie; Bruckman, Amy S. (Georgia Institute of Technology, 2004)
      Creating 3D animations has traditionally been restricted to adult experts. With the advent of easy-to-use software packages like Alice, we can now imagine animations being created by end users with no formal training in ...
    • A Knowledge-Based System for Capturing Human-Computer Interaction Events: CHIME 

      Badre, Albert; Santos, Paulo J. (Georgia Institute of Technology, 1991)
      The ability to capture and analyze human-computer interaction (HCI) data is an important part of the iterative interface development process. In this paper, we claim that in order to perform accurate and extensive analysis ...
    • Knowledgeable Development Environments Using Shared Design Models 

      Neches, Robert; Foley, James D.; Szekely, Pedro; Sukaviriya, Piyawadee (Noi); Luo, Ping; Kovacevic, Srdjan; Hudson, Scott E. (Georgia Institute of Technology, 1992)
      We describe MASTERMIND, a step toward our vision of a knowledge-based design-time and run-time environment where human-computer interface development is centered around an all-encompassing design model. The MASTERMIND ...
    • The Krakatoa Chronicle - An Interactive, Personalized NewsPaper on the Web 

      Kamba, Tomonari; Bharat, Krishna A.; Albers, Michael C. (Georgia Institute of Technology, 1995)
      This paper describes The Krakatoa Chronicle, a highly interactive, personalized newspaper on the World Wide Web (WWW). It is intended for Java-aware WWW browsers such as HotJava, and is architecturally quite different from ...
    • Learning a Rare Event Detection Cascade by Direct Feature Selection 

      Wu, Jianxin; Rehg, James Matthew; Mullin, Matthew D. (Georgia Institute of Technology, 2003)
      Face detection is a canonical example of a rare event detection problem, in which target patterns occur with much lower frequency than non-targets. Out of millions of face-sized windows in an input image, for example, only ...
    • Learning and Inferring Motion Patterns using Parametric Segmental Switching Linear Dynamic Systems 

      Oh, Sang Min; Rehg, James M.; Balch, Tucker; Dellaert, Frank (Georgia Institute of Technology, 2006)
      Switching Linear Dynamic System (SLDS) models are a popular technique for modeling complex nonlinear dynamic systems. An SLDS has significantly more descriptive power than an HMM by using continuous hidden states. However, ...
    • Learning for Ground Robot Navigation with Autonomous Data Collection 

      Su, Jie; Rehg, James M.; Bobick, Aaron F. (Georgia Institute of Technology, 2005)
