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

Joseph J. LaViola Jr.

October 1997


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.
