I had the pleasure this June of presenting my class’s bioinformatics project to attendees of this year’s SEA-PHAGES symposium. Our project was rather abstract, relying on frequency analysis of DNA n-tuples to infer relationships between genomes, and many of the symposium attendees had minimal experience with the specifics of what we were presenting. It was a unique opportunity to see if a visual explanation would help convey what’s a rather technical and non-intuitive topic.
I took advantage of my medium—relying heavily on animation and colour to convey points that I would otherwise have to resort to jargon to explain—
I also used animation to convey context and relevance—particularly important in a math-heavy project:
Animation that is precise and understated is startlingly effective at getting ideas across.
Color was equally important, allowing me to clearly group and organize distinct objects. This was very important for our phylogenetic tree, where cluster relationships between the 60 bacteriophages could clearly be determined based on color.
Using color and motion to convey points allows for more direct communication of concepts—we can process visual information much faster and more intuitively than we can parse text.
On the technical side, my workflow can be broken down into four main components—narrative building, scene construction (in Illustrator), animation (in After Effects), packaging (in PowerPoint). A brief summary of each follows:
Next, I’ll break up the narratives into a series of slides I would like to illustrate. This is a highly subjective task, and slides can be highly simple (static text on a screen), or incredibly complex (animated tree construction). Whatever it is, it gets drawn out in Illustrator, and broken up into layers in preparation for animation.
After all this, I’ve got a composition in After Effects that I can render out to a video. I bring this video into PowerPoint, and use PowerPoint’s bookmark feature to bookmark spots in the video I would like the presentation to pause at.
