A simple model to analyse the activation force in eyeball movements

Abstract

Starting with a proposal to model horizontal eye movements, we study the parameters involved in it. Particularly, we investigate the values that best fit the parameters describing the activation force responsible for horizontal saccades, independently of the task being performed. The fitting process is based on data sets gathered with an eye tracker device. The simplicity of the model allows to profit from analytical expressions useful to simplify the fitting process. Finally, we use our model to obtain the activation force corresponding to a reading task, finding a very good agreement with the experimental data.
