“We Flash designers have to look outside our field for guidelines to help us make out usability decisions. One field that I think can be helpful is interface design, in particular one simple, absolute, and immutable rule of interface design that hold up against the test of time, Fitt’s Law (pronounced Fitizez). Flash designers can apply this law to our field because it involves the way people use their mouse (or other pointing devices) to interact with the computer. The designers of your operating system used Fitt’s Law to determine how the buttons, menus and other elements would appear and act. Flash designers have much to gain from understanding the applications of Fitt’s Law.”
