Eye gaze can be a rich source of information to identify particular interests of human users. Eye gaze tracking has been largely
used in different research areas in the last years, as for example in psychology, visual system design and to leverage the user
interaction with computer systems. In this paper, we present an IR-based gaze tracking framework that can be easily coupled
to common user applications and allows for real-time gaze estimation. Compared to other gaze tracking systems, our system
uses only affordable consumer-grade hardware and still achieves fair accuracy. To evaluate the usability of our gaze tracking
system, we performed a user study with persons of different genders and ethnicities
