CONTROL OF CURSOR POSITION IN COMPUTER DISPLAYS THROUGH EYE MOVEMENT USING NEURAL NETWORKS AND MATHEMATICAL ALGORITHMS

摘要

The aim of this paper is to present a system that allows to control the cursor position in a computer display through the human eye movements. The developed system uses a two-axis voltage measure obtained by an infrared light reflection procedure to determinate the cursor position into a computer display. Two approaches are compared, an algorithmic approach using polynomials and an artificial neural network (ANN) one. Because of the non-linear relation between voltage and cursor position, the use of an ANN is a good solution to solve this problem. An additional advantage of ANN is its incremented flexibility. Tests show that both methods obtain similar results.
