ABSTRACT
We examine the effects of screen size and target movement on selection performance using an experiment based on Fitts' law. Results indicate that small screen sizes reduced pointing throughput by around 20%. Target movement also negatively impacted performance, but the performance difference between static and moving targets was lower on small screen sizes.

Mouse Cursor Movements towards Targets on the Same Screen Edge
GI '18: Proceedings of the 44th Graphics Interface ConferenceButtons and icons on screen edges can be selected in a shorter time than those in the central area because the mouse cursor stops due to the impenetrable borderline. However, we have concerns regarding such edge targets, in particular, pointing to an ...
Comparison of gestural, touch, and mouse interaction with Fitts' law
OzCHI '13: Proceedings of the 25th Australian Computer-Human Interaction Conference: Augmentation, Application, Innovation, CollaborationWe present preliminary results of an experiment to compare gestural, touch, and mouse interaction using Fitts' law. A total of 15 participants were asked to select 100 targets as quickly and accurately as possible using each technique. Selection of ...
EZCursorVR: 2D Selection with Virtual Reality Head-Mounted Displays
GI '18: Proceedings of the 44th Graphics Interface ConferenceWe present an evaluation of a new selection technique for virtual reality (VR) systems presented on head-mounted displays. The technique, dubbed EZCursorVR, presents a 2D cursor that moves in a head-fixed plane, simulating 2D desktop-like cursor control ...
