The opposite problem — having something that looks like a GUI control when it isn't one — can reduce usability even more. We often see text and headlines that look like links (by being colored or underlined, for example) but aren't clickable. When users click these look-alikes and nothing happens, they think the site is broken. (So please comply with guidelines for visualizing links.)
A similar problem occurs when something looks like a button but doesn't initiate an action, or looks like a radio button but isn't a choice. We found an example of this in our current round of studies.

"Perceived affordances" are actions you understand just by looking at the object, before you start using it (or feeling it, if it's a physical device rather than an on-screen UI element).
-
Perceived affordances are especially important in UI design, because all screen pixels afford clicking — even though nothing usually happens if you click.
-
- Users say, "What do I do here?"
- Users don't go near a feature that would help them.
- A profusion of screen text tries to overcome these two problems. (Even worse are verbose, multi-stage instructions that disappear after you perform the first of several actions.)
Drag-and-drop designs are often the worst offenders when it's not apparent that something can be dragged or where something can be dropped. (Or what will happen if you do drag or drop.) In contrast, simple checkboxes and command buttons usually make it painfully obvious what you can click.
Common symptoms of the lack of perceived affordances are:

Nacho Caballerocritical applications, you can often assume that most users have tried the app many times before. You can also often assume that new users will get some training before seeing the UI on their own.

brockmoellerIf Jakob's Law is "users spend most of their time on other websites," then Jakob's Second Law is even more critical: "Users have several thousand times more experience with standard GUI controls than with any individual new design."
