What is Two-Dimensional Purkinje Eye Tracker about?
The document describes a two-dimensional eye tracker that uses the first and fourth Purkinje images reflected from the eye to determine both eye position and direction of gaze. It does this without any physical contact with the eye. The first and fourth Purkinje images move together during eye translation but differently during eye rotation, allowing the device to separately measure translation and rotation. The device is as accurate as eye trackers using contact lenses but is more convenient to use.
