Eye Movement Instrumentation for Reading Research.
Bieger, George R.; Hirschfeld, Rafael
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 reading materials composed of both text and pictures. Equipment discussed included: (1) Gulf and Western Model 106 Eye-trac system; (2) JVC KD-A2 stereo cassette deck; (3) Data Translation DT2762 A/D converter; (4) PDP-11/03 computer system; and (5) Hewlett-Packard 7221B plotter. Software discussed included: (1) MAP--creates a map of target locations in the stimulus; (2) ITRAK--obtains the boundary coordinates of the display region and interfaces the A/D converter and the micro-computer; (3) MATCH--takes the eye movement data from ITRAK and produces a summary listing, on the terminal, of eye positions and the time spent at each location; and (4) PLOT (optional)--makes a scaled reproduction of the stimulus and plots the eye positions on this depiction. Procedures are described for collecting eye movement data in non-laboratory settings such as classrooms. (Author/RL)
