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.
