      Abowd, Gregory D. (Georgia Institute of Technology, 1996)
      The defining characteristic of ubiquitous computing is the attempt to break away from the traditional desktop computing paradigm and move computational power into the environment that surrounds the user. Applications of ...
    • Understanding and Characterizing Program Visualization Systems 

      Stasko, John T.; Patterson, Charles W., Jr. (Georgia Institute of Technology, 1991)
      The general term 'program visualization' refers to graphical views or illustrations of the entities and characteristics of computer programs. This term along with many others, including data structure display, program ...
    • The Use of Different Technologies During a Medical Interview: Effects on Perceived Quality of Care 

      Caldwell, Britt; DeBlasio, Julia M.; Jacko, Julie A.; Kintz, Erin; Lyons, Kent; Mauney, Lisa M.; Starner, Thad; Walker, Bruce N. (Georgia Institute of Technology, 2007-10)
      This two-phase study examines a physician’s use of one of five different types of technology to note a patient’s symptoms during the medical interview. In this between-subjects design, 342 undergraduates viewed one of ...
    • User Interface Constraints for Immersive Virtual Environment Applications 

      Bowman, Douglas A.; Hodges, Larry F. (Georgia Institute of Technology, 1995)
      Applications of Virtual Environments (VEs) are rapidly becoming more complex and interactive. They are not restricted to tasks that are solely perceptual in nature; rather, they involve both perception and action on the ...
    • User Interface Software Tools 

      Foley, James D. (Georgia Institute of Technology, 1991)
      Developing high-quality user interfaces is becoming the critical step in bringing many different computer applications to end users. Ease of learning and speed of use typically must be combined in an attractively-designed ...
    • User Interface Specification Using an Enhanced Spreadsheet Model 

      Hudson, Scott E. (Georgia Institute of Technology, 1993)
      This paper describes a new interactive environment for user interface specification which is based on an enhanced spreadsheet model of computation. This environment allows sophisticated graphical user interfaces with dynamic ...
    • A User Study Evaluating Level of Detail Degradation in the Periphery of Head-Mounted Displays 

      Watson, Benjamin A. (Benjamin Allen); Walker, Neff; Hodges, Larry F. (Georgia Institute of Technology, 1995)
      A user study was performed to evaluate the effectiveness of high detail insets used with head-mounted displays. Ten subjects were given a simple search task that required the location of identification of a single target ...
    • Using 'GT Vibrations' in System Dynamics and Vibrations Courses 

      Yusuf, Imran; Slater, Kurt; Gramoll, Kurt C. (Kurt Clyde) (Georgia Institute of Technology, 1994)
      This paper presents an overview of an interactive multimedia vibrations program called GT Vibrations. GT Vibrations contains a series of modules that deal with elementary vibrations, transient vibrations, and continuous ...
    • 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 ...
