FDBeye is a collection of tools to ease working with eyetracker data. I'm slowly migrating stuff from my junkpile of project specific code into this package. FDBeye is about post-acquisition data processing. What's here now is focussed on my own workflows involving data from SRR Eyelink systems, although some stuff may be more generally useful.
Before you try FDBeye, you might want to look at what else is available. What follows is a list of mostly free and open source eye tracking tools.
I've kept this list short, including only tools whose focus is post-acquisition summarization and analysis, and where the source code can be freely downloaded (i.e., you don't have to ask for it, but some of the stuff I've linked to lacks an explicit Open Source License). I'm sure the list is incomplete. If you know of something that seems like it ought to be included, feel free to add it to the list.
- bdots provides techniques for analyzing eyetracking data, as well as other types of highly correlated data that consist of many consecutive tests. We explain how to set the data up in a fashion for the package to use, how to analyze the data using the built in functions, and how to check the t to the data.

- Get Reading Measures (GRM) is a tool from a commercial vendor, SR Research. It's purpose is to extract conventional regional summary measures from studies of gaze behavior while reading. It is designed to work with Fixation Reports output by their proprietary Data Viewer software. But, I believe, the GRM tool itself is freely downloadable, so I've included it on this list. It can be downloaded from the SRR support forum at https://www.sr-support.com/showthread.php?1289-Reading-Measures-from-Data-Viewer&highlight=Reading+Measures. Access requires login via free account.
