GUI Wars: Web Browser Find Functions: Safari vs. Firefox

This is a great example of using attention research in user interface design. Standard Find functions in programs like Microsoft Word pop up a dialog box. You type what you want to find, then it highlights the word. It’s hard to find that highlighted word a lot of the time.

Firefox improves the search process by making the search box a bar that is part of the main window. Research has shown that attention often is distributed across discrete objects, and switching between objects incurs a cost (Egly, Driver & Rafal, 1994). With this layout, you don’t need to shift your attention between objects (though the search bar is all the way at the bottom):

The highlighted word is not that hard to find, but depending on where the word is, it can be difficult to do. In this case, you don’t incur an attentional shift cost from the Find window to the main browser window, but you do have to engage in costly visual search for the highlight word! Problematic.

The new version of Safari, however, fixes this incredibly well. It has the search bar right at the top, but it dims the entire page that’s not your search term and pops up and highlights in a bright yellow your search term. Luminance, motion, and color uniqueness. Talk about attention capture (Yantis & Jonides, 1984)!:

Making the Find tool part of the main window: excellent. Using animation to induce motion, brightness, and color uniqueness so that you can easily find what you were searching for? Genius.
