    • Analyzing and Visualizing Log Files: A Computational Science of Usability 

      Guzdial, Mark; Santos, Paulo J.; Badre, Albert; Hudson, Scott E.; Gray, Mark H. (Georgia Institute of Technology, 1994)
      Researchers in human-computer interactions know that software can easily be instrumented to create a trace of user events in the interface (which we call a log file) for later analysis. Using these data for studying usability ...
    • Effectiveness of Peripheral Level of Detail Degradation When Used with Head-Mounted Displays 

      Watson, Benjamin A. (Benjamin Allen); Walker, Neff; Hodges, Larry F.; Worden, Aileen (Georgia Institute of Technology, 1996)
      Two user studies were performed to evaluate the effectiveness of level of detail (LOD) degradation in the periphery of head-mounted displays. In the first study, spatial detail was degraded by reducing resolution. In the ...
    • The Effects of Cross Cultural Interface Design Orientation on World Wide Web User Performance 

      Badre, Albert (Georgia Institute of Technology, 2001)
      The electronic environment of the World Wide Web evolves daily, increasing the likelihood of international participants and transactions. With this in mind, we investigated several key issues and questions related to the ...
    • Evaluation of Display Parameters Affecting User Performance of an Interactive Task in a Virtual Environment 

      McWhorter, Shane William; Hodges, Larry F.; Rodriguez, Walter E. (Georgia Institute of Technology, 1991)
      Although the popularity of virtual environments is widely known, little is known about the usability of virtual environment displays. This paper presents experimental data on the effect of virtual environment display ...
    • The Graphics, Visualization, and Usability Center Brochure 

      Badre, Albert; Berger, Marc; Corso, Gregory M.; Davis, Elizabeth Thorpe; Ezquerra, Norberto F.; Foley, James D.; Govindaraj, T.; Guenter, Brian K.; Hodges, Larry F.; Hodges, Laurie Beth; Hudson, Scott E.; Lawton, Daryl T.; Mitchell, C. M. (Christine M.); Morton, Joan C.; Mynatt, Elizabeth D.; Putnam, Bill; Ribarsky, William; Rodriguez, Walter E.; Shonkwiler, Ronald W.; Sinclair, Michael J.; Stasko, John T.; Sukaviriya, Piyawadee (Noi); Trauner, Mary; Walker, Neff (Georgia Institute of Technology, 1991)
      Graphics, Visualization, and Usability (GVU) is an interdisciplinary area which draws its intellectual foundations from Computer Science, Psychology, Industrial and Systems Engineering, and Computer Engineering, and which ...
    • Integrating Perceptual and Symbolic Information in VR 

      Bolter, J. David; Hodges, Larry F.; Meyer, Thomas C.; Nichols, Alison (Georgia Institute of Technology, 1995)
      Inside or outside the lab, most current VR aims at reproducing perceptual experience. The goal is to give the user the sensation that he or she is walking along a hallway in a building, flying over a city, or riding in a ...
    • Sonopticon: Auditory Display in Automobile Interface Design 

      Bayes, Joe; Pair, Jarrell; Shrum, Ed; Tolva, John (Georgia Institute of Technology, 1998)
      The multiplicity of interface elements in an automobile can present a hinderance to usability and safety. We prototyped and conducted preliminary testing of an automobile driving interface. Our key design principle was to ...
    • 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 ...
    • Video Temporal Compression Techniques to Facilitate Usability Evaluation 

      Santos, Paulo J.; Hudson, Scott E.; Guzdial, Mark; Badre, Albert (Georgia Institute of Technology, 1995)
      Video of users' interaction with interfaces is often collected as part of the usability evaluation process. Analyzing the video is a time-comsuming task, because of the length of the video. One way to reduce the time ...
    • Virtual Environments Research at the Georgia Tech GVU Center 

      Hodges, Larry F.; Bolter, J. David; Mynatt, Elizabeth D.; Ribarsky, William; Van Teylingen, Ron (Georgia Institute of Technology, 1993)
      The Grapics, Visualization, and Usability (GVU) Center was established at Georgia Tech in 1991 in recognition of the central importance of these three disciplines to the future growth of computing. The key emphasis ...
    • Visualization and Analysis Using Virtual Reality 

      Ribarsky, William; Bolter, J. David; Op den Bosch, Augusto; Van Teylingen, Ron (Georgia Institute of Technology, 1994)
      Current virtual reality technologies have not yet crossed the threshold of usability. Display resolutions in many cases render the user legally blind. Head- and hand-tracking devices are inaccurate and of very limited ...
