    • Aggregation Bias and the Use of Regression in Evaluating Models of Human Performance 

      Walker, Neff; Catrambone, Richard (Georgia Institute of Technology, 1992)
      Regression analysis is increasingly being used to provide confirmatory evidence for models of human performance. The amount of information made available to judge these models is reduced because clearly established standards ...
    • Anthropomorphic Agents as a UI Paradigm: Experimental Findings and a Framework for Research 

      Catrambone, Richard; Stasko, John T.; Xiao, Jun (Georgia Institute of Technology, 2002)
      Research on anthropomorphic agent interfaces has produced widely divergent results. We suggest that this is due to insufficient consideration of key factors that influence the perception and effectiveness of agent-based ...
    • Applying Spindex Auditory Cues While Driving and Performing A Secondary Search Task 

      Gable, Thomas Matthew (Georgia Institute of Technology, 2015-07-08)
      This thesis investigated the impact of applying “spindex” text to speech (TTS) auditory cues in a long-list searching task on a cell phone while driving as compared to a visuals-only interface. Previous research has found ...

      Eiríksdóttir, Elsa; Xu, Yan; Miller, Andrew; Poole, Erika; Catrambone, Richard; Kestranek, Dan; Mynatt, Elizabeth D. (Georgia Institute of Technology, 2011-07)
      We present detailed findings from our study of a long-term multi-site physical activity pervasive game for US middle school children: The American Horsepower Challenge. In this technical report, we concentrate on the ...
    • Be Quiet? Evaluating Proactive and Reactive User Interface Assistants 

      Xiao, Jun; Catrambone, Richard; Stasko, John T. (Georgia Institute of Technology, 2003)
      This research examined the ability of an anthropomorphic interface assistant to help people learn and use an unfamiliar text-editing tool, with a specific focus on assessing proactive a ssistant behavior. Participants in ...
    • Beyond the Scrollbar: An Evolution and Evaluation of Alternative List Navigation Techniques 

      McCrickard, D. Scott; Catrambone, Richard (Georgia Institute of Technology, 1997)
      List navigation devices such as scrollbars provide a simple way to browse and find items in a list, but they typically do not communicate information about individual list entries. This paper presents two alternative ...
    • The Classroom [Fall 2002]

    • The Classroom [Spring 2004] 

      Llewellyn, Donna C.; McMath, Robert C.; Bobb, Kamau Imara; Shook, David John; Catrambone, Richard; Cotille-Foley, Nora C.; García, Andrés; Hartley, Dana E.; Qu, Jianmin; Magill, Christyn (Georgia Institute of Technology, 2004)
    • Collaborative research: institutionalizing a reform curriculum in large universities 

      Schatz, Michael F.; Catrambone, Richard; Marr, Marcus (Georgia Institute of Technology, 2011-01-04)
    • 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 ...
    • An Empirical Study of the Effect of Agent Competence on User Performance and Perception 

      Catrambone, Richard; Stasko, John T.; Xiao, Jun (Georgia Institute of Technology, 2004)
      We studied the role of the competence of a user interface agent/assistant that helped users to learn and use a new text editor. Participants in the study made a set of prescribed changes to a document via the editor with ...
    • Evaluating Animation as a Mechanism for Maintaining Peripheral Awareness 

      McCrickard, D. Scott; Stasko, John T.; Catrambone, Richard (Georgia Institute of Technology, 2000)
      Animation is becoming increasingly used to communicate information within some limited viewing area. Little is known, however, about the effectiveness and the possible distractions of animation used in this way. This article ...
    • An Evaluation of Space-Filling Information Visualizations for Depicting Hierarchical Structures 

      Stasko, John T.; Catrambone, Richard; Guzdial, Mark; McDonald, Kevin (Georgia Institute of Technology, 2000)
      A variety of information visualization tools have been developed recently, but relatively little effort has been made to evaluate the effectiveness and utility of the tools. This article describes results from two empirical ...
    • Framework for Comparative Research on Relational Information Displays 

      Park, Sung Jun; Catrambone, Richard (Georgia Institute of Technology, 2006)
      We identify critical issues in comparative research on relational information displays (RIDs). The key argument is that when conducting an analysis of the cognitive process of people viewing different displays, their ...
    • Interaction of instructional material order and subgoal labels on learning in programming 

      Schaeffer, Laura M. (Georgia Institute of Technology, 2015-12-04)
      Expository instructions, worked examples, and subgoal labels have all been shown to positively impact student learning and performance in computer science education. This study examined whether learning and problem solving ...
