#8 – Breaking Convention
The employment of novel or original responses to previously familiar interface elements is a common mistake found on websites.
Although this type of error is traditionally well-intentioned, the mistake lies in discounting the familiarity that most people associate with common features of computers and existing software programs.
In fact, using conventions from the “real world” has long been an effective way to ensure a sense of familiarity in a user’s dealing with computers in general.
For instance, everyone instantly recognizes their computer “desktop” because it’s a concept from their everyday life. Using the metaphor of the top of a user’s “real world” desk is an extremely convenient method for guiding the type of behavior that is valid on their “virtual” desktop.
Familiarity is a very powerful concept when it comes to the efficacy with which users interact with their world, real or virtual. And of course, this type of convention is also very useful in the World Wide Web.
For example, it’s very common for a website’s logo to double as a link to the site’s homepage. Now put your self in the place of a user who’s been trained by years of experience that clicking a logo will link to the website homepage and then suddenly this convention no longer applies.
Although this is a rather simple example, you can see how even something so insignificant might affect user enthusiasm for your website.
There are a ton of similar conventions that people are used to from their prior experience that should be accounted for in proper interface design. And most times, the features that break with convention will seem innovative. After doing some user-testing, however, the novelty is found to come at a steep price: user competence.
The lesson is: don’t switch up a decade’s worth of convention unless you’re sure that your users are ready for it and that the benefits of having them learn this new behavior association are greater than the additional confusion created by the unfamiliarity.
Ask yourself if you are accounting for these learned behaviors in your interface. Are you tripping your users up unintentionally by breaking with convention?
