Experiment Description
This experiment replicates the early studies investigating Fitts's Law, as detailed in Welford's book. It involves having participants move their mouse as quickly as possible between two vertical stripes on the screen (which vary in size and distance apart).
Fitts's Law describes the relationship of distance from current location and size to speed and accuracy. Basically, the closer and larger a target is, the easier it is to find.
Experiment Instructions
In this experiment participants see two vertical green strips. The strips vary in their width and distance apart for each trial. Click on one of them, then the other, as fast as you can. Continue to alternately click on each of the two strips until the trial ends. This experiment has 16 trials.
