Query: Graphical Perception in Animated Bar Charts   Interactive visual applications create animations that encode changes in the
data. For example, cross-filtering dynamically updates linked visualizations
based on the user's continuous brushing actions. The animated effects resulting
from these interactions depends both on how interaction (e.g., brushing speed)
controls properties of the animation such as frame rate, as well as how the
data that is being explored dictates the data encoded in the animation. Past
work has found that frame rate matters to general perception, however a
critical question is which of these animation and data properties affects the
perceptual accuracy of judgement tasks, and to what extent. Although graphical
perception has been well studied for static data visualizations, it is ripe for
exploration in the animated setting. We designed two animated judgment tasks of
a target bar in an animated bar chart and empirically evaluate the effects of 2
animations properties - highlighting of the target bar and frame rate - as well
as 3 data properties that affect the target bar's value throughout the
animation. In short, we find that the rate and timing of animation changes is
easier detected in larger values; that encodings such as color are easier to
detect than shapes; and that timing is important - earlier changes were harder
to perceive as compared to later changes in the animation. Our results are an
initial step to understanding perceptual accuracy for animated data
visualizations, both for presentations and ultimately as part of interactive
applications.
