Eye-tracking technologies enable precise measurement of eye movements and are widely used in visual behavior analysis and biomedical engineering applications. Oculomotor parameters, such as fixation duration, saccades, and pupil dilation, are influenced by both visual stimulus characteristics and emotional state; however, the relationships between these factors are difficult to model in a coherent manner. In this context, this paper proposes a model for describing the influence of wavelength and emotional parameters on eye movements. The model expresses oculomotor parameters as functions of the input variables, using simplified relationships that allow both interpretability and practical implementation. To analyze the model, a MATLAB-based application was developed, enabling the simulation of oculomotor behavior under different scenarios. The obtained results highlight variations in the analyzed parameters depending on the input conditions and support the applicability of the model in biomedical monitoring and visual behavior assessment.
