"Psykinematix is the most powerful and affordable standalone solution dedicated to Visual Psychophysics running on Mac OS X. It consists in a unique OpenGL-based software package that does not require any programming skill to create and run complex experiments. Easy to use, subject-friendly, powerful and reliable, Psykinematix runs standard psychophysical protocols, presents complex stimuli, collects subject's responses, and analyzes results on the fly."

What Do Users Say About Psykinematix?

I have recommended Psykinematix to students because it is a quality fast-track solution to experiment design and development.

Max Farrell-Whelan, Macquarie University

Psykinematix is an excellent tool for the rapid and accurate development of psychophysical testing. It allows for the swift conversion of ideas into experiments.

Ben Thompson, University of Auckland

The free demo version of Psykinematix is also a great learning tool to introduce visual perception and illustrate psychophysical concepts to students. To learn more about the use of Psykinematix in clinical research, check out our VSJ 2009 paper: "Psykinematix: A New Psychophysical Tool for Investigating Visual Impairment due to Neural Dysfunctions".
