I came across this idea on the TED blog. It’s a concrete solution to the universal problem of writing slides with way too many words on them, and then reading them.
First, a quick review of presentation tips.
To start, never read your slides, ever. Everyone in your audience can read, so why are you reading for them? Reading your slides is the best way to get people to disengage, and it also disempowers you as the speaker—you want us to pay attention to you and to what you say, and you don’t want to fight it out with your slides.
Second, if you’re giving (versus sending) a presentation, limit yourself to six words per slide. Yes, six. If this idea is new to you, check out Seth’s famous post on Really Bad Powerpoint. I know you’re telling yourself this is impossible, that there’s no way you could write a whole presentation with six words per slide (and great images). But it isn’t: one idea per slide, described by a great image with up to six words, is possible and powerful. Give it a shot.
And finally, if you’re putting more than six words on a slide, and you’re not going to read them, what do you do? Here’s where the dupe and mask comes in. The example on the TED blog is of a busy webpage in which the presenter wants to focus in on just one thing – views of this talk, in this example.
You could do this for any busy slide, and it’s a visual reminder to only present one idea per slide. Even if you don’t literally gray out 90% of the slide in your presentation, dupe and mask is a preparation tool to figure out the one idea this slide is here to communicate. Plus, it’s a great way to remember not to meander around, jumping from circle to circle, and fall back into the trap of sort-of-reading it.
A final suggestion is to keep things moving. Limit yourself to 20 seconds per slide. I just made that number up. It might be 25, or 30. It’s not two minutes though, unless you’re telling us a story (in which case you have all the time in the world). By keeping your internal clock attuned to how long you’ve spent on this one idea, you’re more likely to keep your audience with you by maintaining forward momentum.
What this all boils down to is this: your presentation is about the ideas you’re here to share. Whatever visual aids you bring as support should accentuate and illustrate, but they are not the story. You are the storyteller, and we’re hear to hear what you have to say.
