Welcome!

I am interested in dynamics of visual perception and my favorite way to study it is by using multi-stable displays.

I work at the University of Bamberg, Germany

Software


edfR, import Eyelink data into R

R package to import eye tracking recording generated by SR Research Eyelink eye tracker from EDF-files. It includes options to import events and/or recorded samples and extract individual events such as saccades, fixatoins, blinks, and recorded variables.

Install from github respository

library("devtools");
options(devtools.install.args = "--no-multiarch") # only relevant for Windows
install_github("alexander-pastukhov/edfR",dependencies=TRUE)


edfImport, Matlab toolbox

This library provides a simple interface to import contents of the EDF files generated by Eyelink eye-tracker into Matlab. It imports events and/or samples, automatically parsing them into separate trials. In addition to that, several post-processing functions can be used to extract selected events (fixations, saccades and blinks), variable values (TRIAL_VAR events) and microsaccades.

Download source files and the manual from the OSF repository or clone the github respository.


BiDimensional regression, R package

Package to calculate the bidimensional regression between two 2D configurations following the approach by Tobler (1965).

Install from github respository

library("devtools"); install_github("alexander-pastukhov/bidim-regression",dependencies=TRUE)
