This repository contains a table with parameters (including time to fixate - TTF parameter) and an R script for statistical analysis. This is supplementary material for the paper titled "Effectiveness of a Time to Fixate for Fitness to Drive Evaluation in Neurological Patients" and authored by Nadica Miljković and Jaka Sodnik (published in Behavior Research Methods and previously shared on arXiv). TTF parameter was calculated in overall 56 patients during selected scenario with pedestrian collision in a driving simulator produced by Nervtech. Together with other parameters, ST parameters are stored in tableParametersAll.csv, while R programming code for statistical analysis of all parameters is placed in statisticalAnalysisAll.R. Dataset contents tableParametersAll.csv, table with parameters, csv (comma-separated values) format statisticalAnalysisAll.R, code in R programming language for statistical analysis Table with parameters has the following structure column - no which is ordinary number in consecutive order from 1 to 56 column - id presents an internal patient's id column - ttf presents TTF parameter in ms column - fitness presents a categorical variable and can be either fit-, unfit-, or conditionally-fit-to-drive (cond fit) column - speed at the collision onset in km/h column - ttc presents time-to-collision in s column - manual_correction is categorical variable: 0 means that no manual correction was required for ST calculation, while 1 means that manual correction was required column - igd presents initial gaze distance in pixels column - R1 presents the first measurement of perception response time (PRT) column - R2 presents the second measurement of PRT column - R3 presents the third measurement of PRT Missing data are presented with NA (Not Available). NOTE: Python code for ST calculation and sample eye tracker video are available on GitHub repository https://github.com/NadicaSm/Time-To-Fixate-Calculation-from-the-Eye-Tracker-Videos under GNU GPL license and released on Zenodo with doi (https://doi.org/10.5281/zenodo.6560419).
