Style and Substance in Presentation Style
I first realized that my style of giving a talk was old-fashioned when I spoke at TEDxNYED in 2010. During setup, I asked for a lectern–I wanted to be able to see my slides while I talked. The staff argued with me–are you sure? I was sure. My slides–horrors!–had bullet points of text on them, and few images. I was the only one. Everyone else had slides with single images that faded from one to the next, or perhaps a single evocative word.
The current fashion in presentation style is a triumph of style over substance. When I design slides, I use text to emphasize the main points. If I am telling a charming story, the point is on the slide. This is why I am telling you this story. My talks have content.
Of course images can be content too. Sometimes pictures are actually data. A couple nice examples come to mind from the recent CSCW conference in Vancouver. Nicki Dell from UW presented a paper about people in developing nations struggling to fill in paper forms, and photos of her subjects with giant stacks of paper told the story better than words. Similarly, Lynn Dombrowski from UCI discussed how hard it is to help people to sign up for public assistance. She didn’t have photos from her field site she could put in a presentation, but she was able to find images of real people in similar situations–freely available with a Creative Commons license. I’m more a verbal person than a visual one, but even I get the value of well-chosen images. But a photo that is actual data or closely related is not the same thing as one that just sets a mood. Raise your hand if you’re tired of flowers and mountain streams used to evoke abstract concepts in computing. Sometimes I want to ask, is this a research presentation or a greeting card?
It’s not really pictures I object to–use a sunset if you must. I object to the absence of words. Sometimes the cliché “a picture is worth a thousand words” is simply not true.
The image-focused style of giving a talk goes back to the introduction of the Pecha Kucha presentation style in 2003. It was originally intended to keep talks fast paced and engaging. Don’t get me wrong–I believe talks should be entertaining and engaging. And I’m not advocating a return to overhead transparencies. But I prefer to engage people by presenting content that is meaningful and relevant–not just pretty. Text on slides helps keep people focused on the ideas I’m trying to convey.
I’m proud to use an old-fashioned talk style. Maybe in the future it’ll become hiply retro.
