A button is a button right? Move the mouse over it. Click. Not much to it, eh?

Well, when it’s a well-designed button, all the work your brain is doing to click the button is invisible to you. However, when it’s poorly designed, things start to become harder. Maybe you overshoot the target area? Or maybe you have trouble clicking because the button is too small. Often its not difficult to recover, but it costs attention and attention is expensive.

In this week’s podcast, we discuss the implications of Fitts’ Law. In short, the law states, “The time to acquire a target is a function of the distance to and size of the target.”

In this week's podcast, we discuss the implications of Fitts' Law. In short, the law states, "The time to acquire a target is a function of the distance to and size of the target."

While this seems obvious, it's surprising how often it's forgotten and the trouble that causes. And there's magic that can happen when a designer takes special care to use Fitts' law to its full advantage. Listen to the podcast to hear about how that can work.
