Abstract—Eye tracking has a long history in the field of medical and psychological research as atool for recording and studying human visual behaviour. Real-time gaze-based text entry can also be a powerful mean for communication and control for people with physical disabilities. Following recent technological advances and the advent of affordable eye trackers, there is a growing interest as well as need in pervasive attention-aware systems and interfaces that have the potential to revolutionize mainstream human-technology interaction. In this chapter, we provide an introduction to the state-of-the art in eye tracking technology and gaze estimation. We discuss the challenges involved in using a perceptual organ, the eye, as an input modality. Examples of real life applications will be reviewed, together with design solutions based on research results. We are also going to discuss the process to match the user requirements and key features of different eye tracking systems to get the most suitable system for specific task and application.
