Hierarchy and Aesthetics: Separating Science from Art in Visual Design
In this post I argue that we need to communicate the differences between the science and art of Visual Design better to help change the common perception by stakeholders and clients that user experience is purely subjective.
One of the most difficult aspects of visual design is finding the right science:art ratio to accomplish user goals. I’ve always subscribed to what Tim van Damme calls the mathematics of design. You start with the science:
If art is about talking and expressing yourself, interface design is about listening and disappearing into the background. You listen to the content and its context, and take it from there, one step at a time. Don’t worry about the looks, just start with the variables. 1 + 1 + 1 + “¦ Baby steps, over and over again until what you have on your screen feels right.
And then you mix in art where appropriate:
But sometimes, even 1 + 1 is too much to handle, and you need to clear your head. This is where art comes into play, in the broadest meaning of the word: Paintings, illustrations, architecture, human beings, even nature is art. They won’t help you decide whether you should draw a 1 or 1.5 pixel highlight, but allow you to take a step back and just decide on what’s more suitable or pick one and move on.
Of course, this is not a serial process. Great designers are able to design within that delicate balance between science and art, and find the right ratio as they’re doing it. And even though it’s not easy, I do feel that most designers inherently get this – that visual design is science and art combined in different levels based on the needs of the user and the application.
What’s even harder is explaining this to stakeholders and clients in a convincing way. Over the past week I’ve seen so many comments about how “UX is subjective” and “standards always change” that it got me thinking about a possible solution to this problem. I haven’t figured it out, but I’d like to write down some initial thoughts for discussion.
The problem with Visual Design
I think as a UX community we’ve done a good job of splitting out the different elements of UX Design. Stakeholders and clients are slowly starting to understand the difference between Information Architecture, Content Strategy, Interaction Design, etc. And most people also now understand that those functions are not just gut feel or whatever is the trend of the day. We’ve done a decent job of showing the evidence behind the decisions we make – thanks in large part to the results of user experience research methods like ethnography and usability studies.
But Visual Design is the odd one out in this equation. It walks the line between science and art so tightly that most stakeholders and clients only see the art part. So they look at a design, make a gut call, and think that it’s all just whatever style the designer fancied on that particular day. Sure, some of it is our own fault, and many designs don’t have enough science at all. As Zeldman pointed out:
When Style is a fetish, sites confuse visitors, hurting users and the companies that paid for the sites. When designers don’t start by asking who will use the site, and what they will use it for, we get meaningless eye candy that gives beauty a bad name “” at least, in some circles. Not enough designers are working in that vast middle ground between eye candy and hardcore usability where most of the web must be built.
We have to find a better way forward.
Breaking down the elements of Visual Design
So how do we fix this? One way is to provide a much clearer distinction between the different aspects of visual design. I’m not saying we should split the job title into two functions, I’m saying we should be more explicit about the goals and outcomes of visual design. And it needs to be simple, so it can’t be too detailed. I’m not 100% sure how to do that yet, but here is one suggestion:
- Hierarchy Design could refer to decisions made during the design process that sets the appropriate visual hierarchy based on the scientific principles of visual perception (such as contrast, grouping, balance, symmetry, etc.). See Designing for the Mind as an example.
- Aesthetic Design could refer to decisions made during the design process to help the design fit the brand promise and elicit an appropriate emotional response (such as choice of color, typography, button styling, etc.). See In Defense of Eye Candy for more.
Now, as I already mentioned, there is a lot of overlap between these activities, and you can’t have one kind of visual design without the other. But there has to be a way for us to talk to our stakeholders and clients about the visual layer of design that is not based on style preference but on “hardcore usability” as Zeldman puts it.
As we continue to grow and define the different elements of user experience I believe that Visual Design has the most baggage to overcome simply because of the history of web design and its initial focus on what’s pretty vs. what works. What works is not subjective, and we need to communicate that effectively to our stakeholders and clients. It’s not their fault for not “getting it”, it’s our fault for not explaining it properly. Let’s change that.
