Hi, 

I am currently working on implementing an anti-saccade paradigm from the Millisecond library. Most of the library tasks I’ve found seem to be preconfigured specifically for Tobii hardware, but my lab uses an SR Research EyeLink system.

In the script I’m looking at, the eye-tracker is defined like this:
<eyeTracker>
/ plugin = "tobii"
/ fixationWindowLength = "15"
/ minFixationTime = "50"
/ maxFixationTime = "100"
</eyeTracker>


Since I am new to the technical side of plugins and don't have access to my hardware for another few weeks, I wanted to ask about the general interchangeability of these settings:
  • Can I simply change the / plugin attribute ("tobii" to "srresearch") and expect the rest of the task to run?
  • Are there any technical adjustments (like calibration routines or data messaging) that typically need to be rewritten when moving a task from one tracker brand to another?
Your support is very much appreciated!
