Abstract

Studies of cursor trajectories can help explain performance differences in "point and click" tasks. As users can have different difficulties with moving the cursor to a point on the screen, as compared with pressing a button to select an object, it is helpful to study the two stages of the interaction separately. This paper proposes a method of partitioning a cursor trajectory into a travel and a select phase. The movements of motion-impaired users are studied to show that, by analyzing the two phases separately, it is possible to capture aspects of movement that may otherwise be lost.
