There was quite a buzz on Twitter about a prezi a few weeks ago, that was created by Brian Shire, and presented in Tokyo at this year's annual PHP Conference. Shire, who works as an engineer at Facebook in California, says he really likes to create relations and deep analysis in Prezi. In his approach Prezi is a great tool if you want to show a massive amount of data and show an eye popping presentation in one.
Continuing our interview series, we present a short Q&A below with Brian, who kindly took time to answer our questions and explain his professional view on how to create a good prezi.
Brian, first a little bit about you: what is your job at Facebook, and how have you decided to use Prezi for your international speeches?
I started at Facebook writing front-end products such as Notes and Discussion Boards, but for the last 3-4 years I've focused on performance in PHP Internals and APC (an opcode cache for PHP) specifically. The next logical step was to start giving talks at conferences about APC, which I was initially doing in Keynote. Around the same time I was able to attend a lecture by Edward R. Tufte, his description of modern presentations as an "Endless parade of slides" was very applicable and when I spent a year or two searching for alternatives that could bring more rich interactive displays especially for technical material. But this meant writing up a presentation in something like Flash or Java, which wasn't really appealing or realistic. When I came across Prezi I knew this was a much improved format for what I needed. Scalable data presented in an interactive way yet still easy to create and manipulate for the presenter. I re-wrote my existing presentation for APC in prezi, and never thought of going back after.
Have you found easy or hard to swicth to a slideless presentation tool?
At first I found the switch difficult, but more in the sense of wanting to be more creative and thoughtful about how things where presented. I still want to improve on this, it's far from perfect, but that's what makes Prezi better. With other tools, improvements are often made by say changing color, adding charts, or other eye candy (what Tufte would call Crud). These aren't actually changing how you present data, they are really just obscuring it. With Prezi I'm thinking more about how obvious it is to the audience, if it flows well, if it's interesting and appealing not my slide templates or chart junk (although I still toss in a few images every now and then for fun, sorry Tufte).
What are the most interesting potentials of Prezi for you?
I'm really excited about every presentation being expected to meet a higher standard. Currently if you're presenting to many hundreds of people, have time, and a large budget you can create an amazing presentation. But I think Prezi makes this level attainable for everyone presenting information. I want to see every talk, no matter how large or small, present data in an interesting and meaningful way. I want also want people to present more data than what you can with traditional slide show presentations, I think the ratio of actual data presented in today's talks is pretty low. Presenters often have to sacrifice interest factor for data. We should actually get more interesting with more data not the other way around. I also hope to see users start to push the creativity level in their presentations and come up with things that we haven't necessarily thought of doing before, Prezi makes and I think will continue to make this possible for users.
About the prezi you made for the PHP Conerence: what was your main message
you wanted to visualize with it?
I wanted to create a feeling of components nested in a larger system. Being a topic that is very technical, even for a technical presentation, I wanted to make sure we could break items down into very concrete elements so that they where in an ideal form for learning. I also wanted to give it a free-flowing and "active" feel. There's always some portions of any talk that are probably more appealing than others, especially in a technical discussion. Part of my job is to make sure we get through the "boring" parts to things that the audience can actually take with them back with them to get something beneficial done. Prezi suits these goals well, but now I know the pressure is on me to try to be more creative rather than just fitting data to a pre-built template.
When you worked on the prezi: what was your method to build relations and
arguments?
One is to use the frames and arrows (or whatever other items you wanted, these could also be scalable graphics etc). I then combine these in a way that I would if I was creating a flow graph, but with Prezi I can walk through and zoom into each of these levels. Even if you can't see all the details early on you can still see a high level view of everything, where we are going, and even show it all again after it's been explained.
Another method I used was to keep context by zooming way into some object and displaying a much more detailed explanation. For example having a really high level statement, and then zoom into the white-space between the text and provide a detailed flow so that we didn't loose context for the audience. This is something normal presentations can't do, or have to do in such a boring way they loose half the audience, by zooming in we keep context and can actually keep someone's attention.
These are both particularly useful for code examples where code can be difficult to read, or can really create a loss of interest.
The zooming can really key into what's relevant and not be an eye sore.
How much time did it take to finish the project?
Like everything, a lot of this is a progression, and I try to update my presentations for every conference. I would estimate that I probably spent a week or two playing with different things, but in the end actual time spent was probably only like a day to create a presentation like this. I created my recent presentation for Rakuten in about 4 hours.
What was the feedback from your audience? How do you think Prezi
helped explaining such a complex topic to the audience?
The feedback has been great, and is one of the primary reasons I continue to use Prezi (after all if it's not working for the audience there's no point). Someone always asks about the presentation tool I used for this, and I think often times they are surprised when I give them a URL to go to to create one of their own online. I think they where expecting something more heavy weight or inaccessible. The organization allows for good context and association, but it also keeps the slides interesting. It helps the audience feel more like they are actually getting a presentation, rather than just being read to.
