Analysis of Mouse Movement Time based on Varying Control to Display Ratios using Fitts' Law

Joseph J. LaViola Jr.

October 1997

Abstract:

This paper describes an experiment that attempts to determine what impact different control to display ratios will have on movement time of a mouse in a set of static tasks. The experiment shows that an increasing control to display ratio will actually increase the time it takes to perform a given task with a mouse. Linear regression models were built using Fitts' law to get a correlation between the five different control to display ratios that were used. A discussion of how the experiment was conducted and analysis of the results will be provided.
