This site provides a Web-based interactive experiment (using Java plugin) that allows users to see how their motor skills compare with Fitts' Law, which states that the time to acquire a target is
a function of the distance to and size of the target. The law has been cited as proof that the Windows task bar unnecessarily gets in people's way, since it indicates that the most quickly accessed targets on any computer display are the four corners of the screen. This experiment takes about 3 minutes to complete, prompting the user to click on 50 target points. After the clicks are collected, the results are plotted, showing how the user responses compare to those predicted by Fitts' law. In a few months, the project plans to post a copy of its report on how well these models perform, based on the timing data from the users who have participated.
