The capabilities of developing eye tracking for AR systems on the base of a microcontroller Raspberry Pi

Abstract

This article describes eye tracking technology as a prospective application for AR systems, opening opportunities for dynamical focus, attention mapping and the interplay between a user and a device. Described eye tracking system is an integration of a microcontroller and a camera module. The software uses algorithms for detection a pupil, determination of its position and calculation of the gaze vector for each eye. Gaze tracking is a basis for such technologies as dynamical focus and attention maps, which use the sight vectors as initial data. AR system with basic tracking functionality is developed on the base of multifunctional microcontroller Raspberry Pi which makes project available for a wide community of students and developers by minimal cost.
