Eye Tracking in Virtual Environments: The Study of Possibilities and the Implementation of Gaze-point Dependent Depth of Field
Bartosz Bazyluk · 2010
In this paper we present the application of an eye tracker as an innovative real-time virtual environment interaction device, that enables a new level of control, and forms a base for many realistic sight-dependent visual effects. Current use and main stream of research regarding eye tracking technology aims at marketing and usability testing, as well as help for people who suffer from manual disabilities. The goal of our work is to spread interest in other uses of this advanced and impressive technology. Apart from the discussion about possible uses of eye tracking in the computer-generated worlds, we provide a complete case study of a depth of field post processing effect for realtime graphics, that relates on the user’s gaze point.
