Lecture 18: (even more) Open Problems May 1, 2017 SDS235: Visual Analytics

Announcements Final Project Reception: Wednesday 6pm in Hillyer Atrium FP5 Write-ups due May 12th by 4:59pm Office hours tomorrow 11:30am – 1pm and by appointment

Details on Final Project Write-ups 1/2 Abstract and introduction: what is the big question your system answers? Who is it helping? Description of your data: what it looks like, where it came from, and how you collected it / enriched it A discussion of the visualization techniques you chose, and why they make sense for your application An evaluation of your system (this can be a self-evaluation, an expert critique, a user study: just justify the choice) Any future directions you would like to explore

Lesson 3: Improving Memorability Borkin, Michelle, et al. "What makes a visualization memorable?." Visualization and Computer Graphics, IEEE Transactions on 19.12 (2013): 2306-2315.

Open Question: Does Memorability Matter? “Visualizations don’t need to be designed for memorability – they need to be designed for comprehension. For most visualizations, the comprehension that they provide need only last until the decision that it informs is made. Usually, that is only a matter of seconds. When the comprehension has lasting value, it should be stored in memory, not the visualization.” “Information Visualization Research as Pseudo-Science.” Stephen Few, Perceptual Edge.
