PyGaze - Open-source toolbox for eye tracking in Python

Description

PyGaze is an open-source toolbox for eye tracking in Python. It has an uniform and user-friendy syntax and it is aimed for people with minor to advanced programming skills in Python. Pygaze acts as a wrapper around several existing packages, among which PyGame, PsychoPy, pylink (for SR Research EyeLink systems), SensoMotoric Instruments’ !iViewX API, and the !Tobii SDK. From stimulus presentation to eye-tracker communication: everything can be handled by via PyGaze scripting. As a a Python library for eye tracking you can use a set of plugins that will allow you to use PyGaze from within OpenSesame. You can install PyGaze on Windows as well as on Ubuntu.

PyGaze supports the following eye trackers:

• EyeLink — For information on how to run OpenSesame with PyLink support
• EyeTribe — Works out of the box.

Advantages of PyGaze:

• user-friendly platform
• saccade detection algorithm (for online detection)
• sharing code is easy (works on Windows, Linux and Mac OSX)
• creating eyetracking experiments in Python syntax with the least possible effort
• can be used for visual and auditory stimulus presentation; for response collection via keyboard, mouse, joystick, and other external hardware

Project Anatomy

Community: PyGaze community

Leadership: Edwin Dalmaijer

Forking: Fork your own copy at this address ​https://github.com/esdalmaijer/PyGaze, for which you will need a GitHub account.

Communication: There are a couple of ways for communicating with PyGaze developers, one is their support forum accessible from ​http://forum.cogsci.nl/index.php?p=/categories/pygaze and the other is a contact form found at ​http://www.pygaze.org/contact/ (in case you do not want to create a forum account)

Roadmaps:

Original goal:

• bundles of code for a large range of different eye trackers from different manufacturers into a single interface.
• open-source based on excisting libraries

Future goals:

Short term:

• better variable management and getting rid of some annoying bugs
• an analysis suite to complement the existing experimental library

Long term:

• incorporate support for more eye trackers and support for even more obscure peripherals
• support for electroencephalography
