It amazes me that there are so many animated visualizations that are complicated because there are so many moving things happening at once. I used to think that I get confused because the concept is hard to understand, but in fact it is the visualization that is making it difficult. The alternative shown in class is to use static images showing the direction of things happening, which sounds boring compared to animation, but does potentially help tackle the problem. There can be cases were static images are insufficient in conveying something, though. In situations where there are not many things happening simultaneously, animations should be able to aid the user a lot in understanding a concept. Perhaps we can have a way for users to interactively select which part of the visualization to animate so that they can focus on one part at a time. Of course, they would need some guidance for knowing which parts they should choose before others.

After reading the paper by Tversky, Morrison and Betrancourt, I was surprised that animation is largely a failure at conveying information over static graphics. But this may just have to do with the way the research community has approached the problem of evaluating animation. As mentioned in the paper, the utility of an animation is evaluated against a comparable static graphic. The problem is that it's difficult to find a static graphic that is equivalent to an animation in every way except for the animation itself (i.e. same exact same information content). I don't think it's fair to conclude that animation has been a failure. Rather, I think we should take a step back and think about whether we've done the proper evaluation of animation.
