This chapter gives an overview of primarily interactive applications mainly developed by computer science researchers. Following the hierarchy of eye tracking systems given earlier, apart from diagnostic usability studies, this chapter focuses on two types of interactive applications: selective and gaze-contingent. The former approach uses an eye tracker as an input device, similar in some ways to a mouse. This type of ocular interaction is often studied by researchers involved in the fields of Human-Computer Interaction (HCI) and Computer-Supported Collaborative Work (CSCW). The latter gaze-contingent application is a type of display system wherein the information presented to the viewer is generally manipulated to match the processing capability of the Human Visual System, often matching foveo-peripheral perception in real-time. It should be noted that a good deal of previous work discussed in this chapter is based on conference proceedings.
