On February 26, 2015 a simple picture of a dress sparked a viral debate with millions of people arguing over whether the dress is black and blue or gold and white. Even in my own household both my daughters saw the dress as gold and white, while I saw only black and blue. The phenomenon of the dress goes to the heart of this site, it’s all about visual perception.
In a Buzz Feed news article, Cedar Riener, associate professor of psychology at Randolph-Macon College says “We are always making decisions about the quantity of light that comes into our retina. This light, called luminance, is always a combination of how much light is shining on an object and how much it reflects off of the object’s surface. In the case of the dress, some people are deciding that there is a fair amount of illumination on a blue and black (or less reflective) dress. Other people are deciding that it is less illumination on a white/gold dress (it is in shadow, but more reflective).”
In the same article, the dress phenomenon, according to neuroscientist Dale Purves of Duke University, “shows how strongly people are wedded to the idea that colors are properties of objects, when they are in fact made up by the brain.”
As presentation designers, this event showcases the importance of ensuring there is no ambiguity in our visuals if we want to guarantee clarity of our message. On the other hand, look at the “buzz” this photo has generated, including it’s own Wiki page. With a judiciously placed ambiguous image you could leave your audience with a lot to talk about. Artist Rob Gonsalves has some amazing optical illusion photos that would be perfect for this purpose.
The more I learn about visual perception, the more I believe we don’t see at all, we perceive.
In the picture at left, Project Runway’s Season 12 Designer Justin LeBlanc is helping his model into a beautiful faux fur gown, right? Wrong. The gown is actually made from thousands of test tubes. But our brain translates this particular texture as soft fur because that is what we’ve experienced though both our touch as well as sight. Justin engaged our sense of touch (through familiarity) and fooled our eye.
In truth, while our eyes see, our brain’s perceive with all our senses, not just our eyes. And sometimes that means when other senses come into play, it can drastically change what we think we’re seeing.
For example, by simply adding a small sound you can completely change what your audience perceives. You can download the PowerPoint presentation to see what I mean from here: http://sdrv.ms/1eksk6r (and it must be downloaded since Web Apps will not support a looping slideshow). It has only one slide. This particular example was inspired by an episode of Brain Games, which I mentioned in a previous post. If you watch the slide with your sound muted, the two balls will appear to cross over each other. But if you watch it with sound on, the balls will appear to bounce off one another. Try watching it with sound and without sound and you’ll see how dramatic the difference is. Just by adding elements that engage our other senses, you can change (and enhance) what your audience sees.
Ironically, the designer Justin LeBlanc is deaf and this particular dress represents his adjustment to having a cochlear implant. I’d say he did an amazing job with that inspiration. And taught us all a little lesson in perception.
You might not believe it, but National Geographic’s Season 2 of Brain Games is a near perfect resource for presenters and presentation designers. While not perfectly scientifically accurate, the series contains a wealth of information about how our brain processes information and it’s delivered in an entertaining format. This is invaluable information if you are a presenter or presentation designer.
The official Brain Games web site has video clips, articles and the schedule for all 12 episodes. Amazon provides the series in both DVD and streaming format. Episodes are also available through NatGeo’s YouTube Channel for $1.99 per episode.
In addition to the series episodes, National Geographic’s Education web site has more resources on how your brain works and, finally, if you’re curious to see how your own brain stacks up, discover your own brain profile at the Interactive Brain Games web site. I highly recommend you watch the episodes first though or you might find you’re not as clever as you thought you were.
I’ve always loved collages and mosaics. There’s so many aspects to appreciate. From a distance you see the entire picture, but close up there’s all these wonderful details.
Previously I blogged about the Gestalt Principles of Perception and it’s these very principles that allow us to see these pictures, created with small tiles, holistically. They are illusions become art.
I first saw a photography mosaic on a popular decorating show and was immediately captivated. How wonderful to take a collection of images and create your memories as art. After watching the show I knew I just had to find the software that would allow me to create my own mosaics.
Whoever said you can’t get something for nothing never encountered Andrea. This wonderfully quirky person has created a tiny, well-behaved app that easily lets you create your own photo mosaics. The application is, appropriately enough, called Andrea Mosaic. A version is available for virtually every operating system and professional versions are also available for a very small fee of $35. You can even capture images from video and use them to create your mosaics.
There has been some criticism because the interface isn’t elegant and the grammar is atrocious but who the hell cares? Anyone who figures out the algorithms to create these lovely little works of art and gives it away for free deserves a little leeway. Andrea does accept donations and if you use his software I encourage you to contribute at least a small donation.
If you need more professional features consider Mosaic Creator for $99. In addition to photo mosaics you can create tile mosaics, video mosaics, text mosaics and ASCII art.
So the next time you’re looking for a creative gift, a unique banner or sign for an event or an interesting element to add to a presentation, consider a mosaic. It’s sure to engage your audience’s attention and stimulate their minds.
