Modeling the Effect of Target Shape on Movement Performance in a 1D2D Fitts Task

Fitts’ law is used as a performance measurement metric in human–computer interactions. The original formulation implied that movement time was identical for movements with the same value of index difficulty under varied amplitude and target width. An experiment designed to test this implication. result indicates related when constant. Nowadays, most icons applications are represented two-dimensional targets. object equal width height particular case target. This area could be factor Fitts task impact time, number errors, perceived difficulty. Therefore, replace modified easy implement without complexity post-calculation. Researchers can design before empirical test. research proposes by varying target’s applying square-root model simultaneously, which results an excellent higher R-square satisfies residual normality robustly than traditional law.
