TreeMap(TM) Vs. Sunburst(SB)

Experimental Design

Experimental Results Experiment One Experiment Two For file search tasks, people who used SB first did better In both phases. Along with some other results this suggest That SB is easier to learn initially than TB.

Subjective Results 51 out of 60 people preferred SB overall.

Experimental Design Problems 1. Too Many Variables. Attempted to answer too many questions at once. 2. Most Conclusion are NOT statistically significant. Even if they were SS – would they apply? Would the means be different enough to care? Does this apply to all hierarchies? c) What about all those failures we through out? Suggestions Make users perform only one type of task, but over many hierarchies, with more samples.

Questions?
