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.
