We propose the use of virtual environments to simulate augmented reality (AR) systems for the purposes of experimentation and usability evaluation. This method allows complete control in the AR environment, providing many advantages over testing with true AR systems. We also discuss some of the limitations to the simulation approach. We have demonstrated(More)
Because effective navigation in 3D virtual environments (VEs) depends on the specifics of the travel techniques and the display system, we compared two travel techniques (steering and target-based) and two display conditions—a high-fidelity setup (a four-wall display with stereo and head-tracking) and a lower-fidelity setup (a single wall display without(More)
Spatial judgments are important for many real-world tasks in engineering and scientific visualization. While existing research provides evidence that higher levels of display and interaction fidelity in virtual reality systems offer advantages for spatial understanding, few investigations have focused on small-scale spatial judgments or employed(More)
While the primary goal of visual analytics research is to improve the quality of insights and findings, a substantial amount of research in provenance has focused on the history of changes and advances throughout the analysis process. The term, provenance, has been used in a variety of ways to describe different types of records and histories related to(More)
Researchers have proposed that immersion could have advantages for tasks involving abstract mental activities, such as conceptual learning; however, there are few empirical results that support this idea. We hypothesized that higher levels of immersion would benefit such tasks if the mental activity can be mapped to objects or locations in a 3D environment.(More)
— Team politics complicate software projects. They cause internal conflicts that can not only cost a software team time and money, but may also detract from the needs of the product's end users. In this paper, we explore the use of concept maps as a means of mitigating such team conflicts. Approaching agile usability through the lens of distributed(More)
This study explores how spatial layout and view control impact learning. We performed a controlled experiment using a learning activity involving memory and comprehension of a visually represented story. We present our preliminary results comparing performance between a slideshow-type presentation on a single monitor and a spatially distributed presentation(More)
Provenance tools can help capture and represent the history of analytic processes. In addition to supporting analytic performance, provenance tools can be used to support memory of the process and communication of the steps to others. Objective evaluation methods are needed to evaluate how well provenance tools support analysts' memory and communication of(More)
