THE COST OF NAVIGATION

When you walk into an unfamiliar room, you look around. In a fraction of a second, you take in the shape of the room, the furnishings, the light, the ways out, and other clues; very quickly, you make some assumptions about what this room is and how it relates to why you walked in. Then you need to do what you came in to do. Where? How? You might be able to answer immediately—or not. Or maybe you're just distracted by other interesting things in the room.

The "context switch" forces you to refocus your attention and adjust to your new surroundings.

Even if you're already familiar with the window (or room) you just went into, it still incurs a cost. Not a large cost, but it adds up—especially when you figure in the actual time it takes to display a window or load a page.

This is true whether you're dealing with web pages, windows, dialog boxes, or device screens.
