In this article, Chris Bank of UXPin (opens in new tab) – the wireframing & prototyping app – explains how to use the Blur Technique. For analysis of UI examples from over 33 companies, check out the free ebook Web UI Best Practices (opens in new tab).
In the first two articles in this series, How the human eye reads a website (opens in new tab) and 4 key ways to create visual hierarchy (opens in new tab), I examined how to create the appropriate visual hierarchy in your web UI design.
Now that we've discussed how different interface elements affect visual prioritization, let's look at a simple way to test your hierarchy. Designer at Rackspace (opens in new tab) Lee Munroe offers a great method we'll call the Blurring Technique (opens in new tab).
Basically, look at a blurred version of your site (like the one below) and see what elements stand out. If it's not what you want to stand out, it's time to go back and make some revisions.
The blurred version will present a bare bones representation of your visual hierarchy, allowing you to evaluate your interface fresh without any distractions.
To spare your eyesight (or a trip to the bar), take a screenshot of your site and add a 5-10 px Gaussian blur in Photoshop.
Wufoo's homepage (above) passes the blur test because the prominent items are the sign up and product feature buttons, both of which should be priorities on any homepage.
The shape of the sign up bar makes it stand out, while the white space around the features buttons draws the eye by creating "breathing room".
Understanding visual hierarchy and applying design patterns are two of the most important skills in good web UI design. They are fundamental and interconnected: once you know how to visually prioritize information, you'll have a better grasp of how to apply existing design patterns.
Prioritize your interface based on how people scan for information (opens in new tab). Then, apply colour, contrast, color, size and spacing (opens in new tab) for further accentuation. To help shorten the learning curve, you can also turn to UI pattern resources like UI Patterns (opens in new tab) and PatternTap (opens in new tab).
