Scientific user interface testing : exploring learning effects and Fitts’ Law

The Scientific User Interface Testing framework (SUIT) was developed to monitor users in a natural setting and log their behavior. Color-Selector User Interface Testing (C-SUIT) is an online application of SUIT concepts in order to test color-selector user interfaces. The aim of this study was to determine whether learning takes place in the C-SUIT experiments and whether it might prevent Fitts’ law from correctly modeling movement
