Evaluation of noise annotation lines: using noise to represent thematic uncertainty in maps

摘要: Noise annotation lines are a promising technique to visualize thematic uncertainty in maps. However, their potential has not yet been evaluated user studies. In two experiments, we assessed the usability of this with respect different number levels as well influence design aspects noise lines: grain and width grid. We conducted web-based study utilizing qualitative comparison 2 areas 150 recruited participants from Amazon Mechanical Turk majority being nonexperts use Our findings suggest that for comparisons “constant uncertainty” (i.e., constant per area) maps, can be used up six levels. During four, six, eight levels, designs yielded significantly accuracies. propose “large width, coarse grain” desig...
