A method and apparatus for collecting and interpreting eye movement data is described that is both relatively inexpensive and portable. The study lists and describes hardware and software components of a data collection and data analysis system which provides precise information regarding the location, duration, and sequence of eye fixations while…

In the study of perception during reading, the use of eye movement contingent control of the stimulus display has proved to be a useful research technique. With such a system, it is possible to experimentally manipulate, in real time, the characteristics of the stimulus display that is present on selected fixations as reading is in progress and to…
