Automated and interactive analysis of eye fixation data in reading

  • A package of five FORTRAN programs that provides for fast user-controlled analyses of reading eye fixations is described. The package requires the data to be in a fixation format and to be rescaled to screen dimensions. OLDEYE identifies six types of fixations and calculates descriptive statistics on each of them, on their associated saccades, and on their average pupil diameter. CONVRT represents the text as a string of words that can be coded according to experimentally relevant variables. PLTFIX prints fixation durations by letter position and sequence of occurrence. MODDAT is an interactive program for marking parts of the text in which the data quality is below acceptable standards. It also allows the correction of systematic errors due to calibration or drift. MATCH combines the outputs from OLDEYE, CONVRT, and MODDAT and calculates 11 dependent measures for every word. The output of MATCH is suitable for input to conventional multivariate statistical programs.
