Yost, Beth, Haciahmetoglu, Yonca and North, Chris (2007): Beyond visual acuity: the perceptual scalability of information visualizations for large displays. In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 101-110. Available online
“The scalability of information visualizations has typically been limited by the number of available display pixels. As displays become larger, the scalability limit may shift away from the number of pixels and toward human perceptual abilities. This work explores the effect of using large, high resolution displays to scale up information visualizations beyond potential visual acuity limitations. Displays that are beyond visual acuity require physical navigation to see all of the pixels. Participants performed various information visualization tasks using display sizes with a sufficient number of pixels to be within, equal to, or beyond visual acuity. Results showed that performance on most tasks was more efficient and sometimes more accurate because of the additional data that could be displayed, despite the physical navigation that was required. Visualization design issues on large displays are also discussed.”

Shupp, Lauren, Ball, Robert, Yost, Beth, Booker, John and North, Chris (2006): Evaluation of viewport size and curvature of large, high-resolution displays. In: Proceedings of the 2006 Conference on Graphics Interface 2006. pp. 123-130. Available online
“Tiling multiple monitors to increase the amount of screen space has become an area of great interest to researchers. While previous research has shown user performance benefits when tiling multiple monitors, little research has analyzed whether much larger high-resolution displays result in better user performance. We compared user performance time, accuracy, and mental workload on multi-scale geospatial search, route tracing, and comparison tasks across one, twelve (4x3), and twenty-four (8x3) tiled monitor configurations. We also compare user performance time in conditions that uniformly curve the twelve and twenty-four monitor displays. Results show that curving displays decreases user performance time, and we observed less strenuous physical navigation on the curved conditions. Depending on the task, the larger viewport sizes also improve performance time, and user frustration is significantly less with the larger displays than with one monitor.”

Yost, Beth and North, Chris (2005): Single complex glyphs versus multiple simple glyphs. In: Proceedings of ACM CHI 2005 Conference on Human Factors in Computing Systems 2005. pp. 1889-1892. Available online
“Designers of information visualization systems have the choice to present information in a single integrated view or in multiple views. In practice, there is a continuum between the two strategies and designers must decide how much of each strategy to apply. Although high-level design guidelines (heuristics) are available, there are few low-level perceptual design guidelines for making this decision. We performed a controlled experiment with one, two, and four views to evaluate the strengths and weaknesses of these strategies on target detection and trend finding tasks in the context of multidimensional glyphs overlaid onto geographic maps. Results from the target detection tasks suggest that visual encoding is a more important factor when detecting a single attribute than the number of views. Additionally, for detecting two attributes, the trend indicates that reusing the most perceptually salient visual feature in multiple views provides faster performance than an integrated view that must map one of the attributes to a less salient feature.”
