The Fibonacci Method of Dealing with Difficult Clients

Fibonacci Spiral

I love a good Fibonacci sequence, especially one with humor. And a friend (thanks, Rob) recently shared a priceless pricelist that did just that.

We’ve all dealt with those folks who want to be much more involved in the process than is good for them or you. These are typically the ones who want you to bling out every design within an inch of it’s life. They’ll want 3D rotation, shadows, reflections, soft glows, and any other number of effects in an effort to make their visualizations more exciting; obfuscation of the information be damned.

This graphic designer’s pricelist posted on Reddit reflects the frustration of dealing with this type of client by using the Fibonacci sequence to exponentially increase prices based on the level of client interference.

While I certainly understood and enjoyed the humor, I thought “If you’re going to use a Fibonacci sequence, it should be in a spiral” and I set out to do just that.

Since I’d never created a spiral (or rose or fan) chart before, I shopped the web and found this fantastic tutorial by Andy Pope. I’ll admit it took me more than a few moments to understand it, but once I did I realized my challenge would be determining what values to use for the percentage of the radius (the length from the center point to the outer edge of the circle) for each slice. Using the standard percentage as you would for pie chart slices yielded a chart so small as to be useless. I decided I wanted the highest value to be 100% so all I had to do was divide all the values by 3400. This is the spiral chart I created using these values. The ratio is accurate for both the angle of the slices as well as the length of the radius.

And there’s nothing wrong with this chart, but it’s not as attractive a spiral as I’d hoped for and the slices for the first three values are all but invisible. I decided extreme accuracy of the radius length wasn’t as important to me as long as the slice angles were accurate and the radius length still reflected the exponential increase of the values. To that end I went back to my spreadsheet and used the standard percentages plus a weighted value of  .61 (making the highest value 100%). Now the first 61% of the radius length for each slice is equidistant and the last 40% reflects the ratio. Basically I exploded the spiral by 61%. This gave me a more pleasing spiral that still manages to impart the information effectively, though technically less accurate.

I copied the charts into PowerPoint and I admit at this point I got a little lazy. I used a standard PowerPoint theme which I modified slightly rather than design my own. But I think the graphics nicely balances and reflects the curve of the spiral. I also used green to impart the financial aspect. I know it’s cliché, but hey, it works. I briefly considered using leader lines but they would have cluttered up the chart unnecessarily. The data labels were just too difficult to do in Excel so I added them with textboxes in PowerPoint and spaced them appropriately. You’ll notice I also “upscaled” some of the terms.

The Gestalt of Slides

Pragnanz

I recently had the wonderful experience of sharing the Gestalt Principles of Visual Perception with my 4 year old grandson.  This might seem a pretty heady topic for a 4 year old, but we were discussing how shapes can be combined to create a picture of a house.  This is the very heart of the Gestalt Principles of Perception.

The knowledge of these principles can be a very valuable tool for designing not only slides but any form of visual communications, including photographs.

I’ve been working on a post about this topic for a while but, with the inspiration of my experience with my grandson, I decided to make a fully interactive tutorial.  Click the icon in the lower right of the tutorial below to run it in full screen mode.

I hope you enjoy learning from the tutorial as much as I had creating it and, once completed, I wish you the best as you go forward and practice the art of Pragnanz.

Why Should Presenters Care About the Psychology of the Senses?

MouseoverMagicShowThe simple answer is that presentations are intrinsically a sensory experience, primarily seeing and hearing.  And a clever presenter can also incorporate the other senses as well.

But do you really need to understand how the brain processes the information the eye sees or the ear hears?  After all, you don’t need to understand how a computer processes the information from a keyboard to use it effectively.  While this may be true, you do have to have some understanding of how the keyboard works otherwise you’d end of with a mess of letters that made no sense.

The same is true of understanding how our senses work.  You don’t really need to know that the neural circuitry of the retina transforms a fluctuating pattern of light into a pattern of neural activity in retinal ganglion cells, which is then transmitted along the optic nerve to the brain [1].  But it’s extremely helpful to know that we don’t “see” images that move very fast or very slow. 

If you read the report from my previous post, Seeing, Hearing and Smelling the World,  you would know that we are attracted to nothing as much as change.  And that applies to all the senses.  We organize our world into patterns in order to easily filter out unnecessary information and quickly recognize when something changes.  In our primal minds, change represents both danger and opportunity.  These were the tools necessary in an eat or be eaten environment.  Even today these are still the tools that allow us to avoid car crashes or identify food that’s safe to eat.  Whether we want to admit it or not, from a sensory perspective, we all have attention deficit disorder (ADD.)  Anything that doesn’t change every 5 seconds is largely ignored.

I recently attended The Presentation Summit and overheard some patrons who had attended a session on presenting webinars.  They were complaining that the session presenter had said they needed to make a change every XX seconds.   They interpreted this as needing multiple slides for every minute of the presentation/webinar.  I think they missed the point.  Webinars are the ultimate ADD environment.  Your attendees will be checking their email, typing documents or working on a plethora of other activities while you are presenting and you’ll never know it.  You are competing for their attention.  If you do not provide rapid stimulation (change) in your presentation, you will lose your audience pretty quickly.  This doesn’t mean a different slide, the change can be as simple as raising the volume of your voice or a simple highlight on a slide.  You just need some small change that tells their senses “Pay Attention!  Something has changed.”   But beware of repetition which by definition is a sort of unchange.  While a repeating animation might hold our attention for longer than 5 seconds, we’ll quickly learn to ignore it.

By knowing and understanding these concepts you can take advantage of opportunities that most magicians have known about for centuries.  There is truth in the old adage, “the hand is quicker than the eye.”  It isn’t actually, but our brains don’t process everything the eye sees.

Most people have difficulty registering identifying details about an object that moves faster than 36 degrees per second. Since your visual field is around 180 degrees, anything that crosses in and out of your visual field in less than five seconds starts to blur. And because the cells in your eyes get tired of stimulation after more than two or three seconds, anything that doesn’t move significantly in that amount of time will be perceived as stationary. [2]

This is what allows us to make films.  They are simply a series of still images strung together and presented rapidly enough that our brains perceive motion.  You can use this knowledge to add interest as well as dynamic and subtle changes to your presentations.

In my quirky presentation called the Mouseover Magic Show, I used these concepts to do something that the software (Microsoft PowerPoint) is very limited in supporting.  If you download the presentation and run it, you can move your pointer over any mouse and they will appear to change.  In actuality, it’s jumping to a whole new slide, but because the background doesn’t change, we only recognize the change of the mouse.  We aren’t aware the entire slide has changed.  I’ve created this simple slideshow specifically to illustrate this technique for creating mouseovers.

If I’m the PowerPoint Magician, my friend Julie Terberg is the PowerPoint Illusionist.  She applies the concepts of visual motion in an elegant and sometimes surprising way that’s sure to hold an audience’s interest.

PowerPoint 2010 has some new transitions that are specifically designed to exploit this quirk in our visual sense.  They’re called Dynamic Content Transitions.  They provide movement of the content on the slide without moving the background.  You can achieve pretty spectacular effects using just the transitions.  I discussed these transitions on the Indezine Blog and posted a downloadable timeline template that uses these transitions. You must run the template in the desktop version of PowerPoint to see the transitions properly.

Every presentation should have an element of magic to it.  Every presentation should have its prestige (a mysterious quality of enchantment) moment.  Nancy Duarte calls this the STAR moment in her new book, Resonate.  It’s the moment where you’ve connected with the audience on such a primal, emotional or spiritual level that they feel compelled to pay your message forward again and again.  Understanding the psychology of the senses will help you create this moment.

Finally, if you downloaded and ran the Mouseover Magic Show you might have noticed the card trick.  The how and why that works is a discussion for another day.

Seeing, Hearing and Smelling the World

Seeing, Hearing and Smelling the WorldI originally thought my first substantive post would be about the Gestalt Principles of Perception.  However, I realized it would be best to begin by laying a foundation upon which an understanding of the psychology of the senses could be built.

One of my favorite resources is the (now updated) 1997 report from the Howard Hughes Medical Institute on Seeing, Hearing and Smelling the World.  It provides a nice background on how our brains process information using sight, sound and smell.

Welcome to Visualology

Let me start by saying I’ve wanted to write a blog for a while because I love knowledge and I love sharing knowledge.  My problem has been what to blog about.  I knew I wanted it to be about presentations and PowerPoint (which I love.)  My problem was deciding which particular area of my expertise could I write about that would hold the interest of an audience and be the most useful.  Would it be assistive technology, collaboration, interactivity, educational games, information design, digital dashboards, project management, etc.?  My skills in this area are eclectic and usually very technical.  I was looking for that one special topic that could be uniquely mine.  So what was it to be?

I was reading Stephen Few’s books on data visualizations when I finally had my blog epiphany.  One small section covered the topic of the Gestalt Principles of Perception.  I immediately experienced an instance of déjà vu and felt like I’d hitched a ride on Mr. Peabody’s WABAC (way back) machine.

You see once upon a time in a land far away, I was a mental health therapist in the Navy.  In fact, if things had turned out differently I might have been a psychiatrist.  I loved doing therapy and it was especially gratifying to change someone’s life for the better.  And even better than that I met my husband who was also a therapist and I couldn’t have asked for a better soul mate.

But life has a way of throwing you curve balls and sometimes the best you can do is a base hit.

At the time I got out of the Navy work as a therapist was best described as thin and I would’ve had to go to school for 12 years to be able to do the same therapy I’d been doing for the previous 5 years.

So my husband and I made a deal; he’d continue to be a therapist (ultimately earning his Masters in Psychology) and I’d take a different path.  After falling in love with the Commodore 64 and naturally being attracted to the latest, coolest thing it didn’t take much to lure me to the dark side of computer geekdom where I’ve happily lived since.

So here I am, come full circle.  This blog is going to be about psychology.  Specifically, it’s about the psychology of visual perception and how that knowledge can be used to design better presentations and visual communications.  I intend to refresh what I already know and learn what I don’t know and share it here.

Even more, this blog will be my tribute to my husband of 30 years who passed away in 2009.  He would’ve loved this topic and he would’ve loved talking about it, challenging the concepts and expanding our minds and understanding.
