Evaluation of Viewport Size and Curvature of Large, High-Resolution Displays

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 using two monitors next to each other, little research has analyzed whether very large high-resolution displays result in better user performance. We compared user performance time, accuracy, and mental workload on geospatial search, route tracing, and comparison tasks across one, twelve (4×3), and twenty-four (8×3) tiled monitor configurations. Additionally, we included display configurations that involved uniformly curving the twelve and twenty-four monitor displays. Generally, the larger the viewport size the faster users perform. We show that user frustration is significantly less in the twenty-four monitor condition than the one monitor condition. We also show that curving displays increases user performance.
