bETk making eye-tracking analysis simpler.

bETk is a collection of Matlab functions that can be used for the collection and analysis of eye-tracking data. Our hope is to provide both a very simple, standard format for exchanging data between functions and a number of easy-to-understand functions which can be stuck together to create sophisticated, customized analysis scripts.

There are five separate classes of functions:
  1. Data Collection - routines for calibration checking, gaze-dependent presentation, etc. 
  2. Pre-processing - tracker-specific routines for importing data files to bETk format
  3. Basic Processing - finding saccades, fixations, and smooth pursuit
  4. Extended Processing - analyzing by regions of interest in a stimulus
  5. Visualization - ways to understand your data
Contribution: We hope that we are providing a format that will encourage others to contribute code.  If you are interested in participating in the project, please email one of us and let us know.

Disclaimer: You should assume that nothing here really works.  Don't incorporate it into any kind of application that's crucial.  It's all under development and basically just up here to help you and us out.  Contact us if you've got any problems with anything you find here.  Don't be mad, but do give constructive feedback.

Acknowledgement: We are currently preparing a beta version of the bETk; at that time we will submit a poster to VSS so that there will be something to cite.  Until that time, please email one of us to ask about how to give credit for the use of the bETk in any published material.

THESE VERSIONS ARE VERY UNRELIABLE, ONLY FOR DEVELOPMENT!
