The registration of eye movements can be considered the source of information to what is happening in the brain, where most of the information gathered from the visual field is processed. Eye movements can be registered with an eye tracker, a device that detects the position and movements of the eyes. The eye tracking techniques have been used in various fields, for example, in health studies such as Alzheimer's disease.In the last few years our group has dedicated to investigate eye movements from a physical point of view. Recently, we introduced a very simple model of the eye movements as the solution of a driven damped harmonic oscillator. In the present work we return to the investigation of saccadic movements as proposed previously, but having in consideration the decomposition of the movement into eyeball and pupil. Starting with a proposal to model horizontal eye movements, we study the parameters involved in it. We investigate the values that best fit the parameters describing the activation force responsible for horizontal saccades, independently of the task being performed and check the model with reading experimental data.
