A Violation of Fitts' Law is Maintained in Ecologically Valid Settings

J Mot Behav. 2023 Jul 2:1-13. doi: 10.1080/00222895.2023.2210530. Online ahead of print.ABSTRACTA 'violation' of Fitts' Law, or Fitts' Equation, occurs when each potential target location is outlined before and during a reaching movement. Past studies have measured the violation in highly controlled laboratory environments, limiting the generalizability of findings. The purpose of the study was to replicate the violation of Fitts' Equation in the homes of participants using a novel portable apparatus during the COVID-19 pandemic. Movements were measured independently with an accelerometer and touch screen, which allowed for kinematic, temporal, and spatial outcomes to be measured in remote environments. The violation of Fitts' Equation was found with the touch and acceleration measurements and was thus seen in ecologically valid environments. The apparatus used may be used as a model for future field research.PMID:37394465 | DOI:10.1080/00222895.2023.2210530
