Maps are tools used by almost everyone in society for a va riety of applications. However, when maps are used with computers they are almost always used with small, low pixel count displays, such as desktop monitors. We per formed two experiments involving map usage with various tiled display configurations (one monitor, four monitors, and nine monitors). The first experiment focused on basic map navigation tasks and the second experiment focused on how to maximize the effectiveness of the details-on demand interactive technique with large, high pixel count displays. We conclusively found from the experiments that finding objects and route tracing in maps was performed on average twice as fast on the nine monitors as the one mon itor. We also found that participants on the nine monitor configuration had 70% less mouse clicks, 90% less window management, and a general accuracy and performance im provement over the one monitor. This indicates improved insight for large, high pixel count displays.
