eyelink sr eyetracker custom calibration

S F — Thu, 25 Oct 2018 15:20:19 GMT

Hi!

You guys put out a custom 3-point calibration which is great! I was just wondering if there's some way to use multiple calibration stimuli, or a movie instead of a gif, or to play audio at the same time. Even being able to use multiple gifs would be great. I tried ("ag5.gif", "pinwheel.gif") for /calibration stimulus and that doesn't work.

<eyetracker>
/ plugin = "srresearch"
/ aoidurationthreshold = 100000
/ calibrationstimulus = "ag5.gif"
/ calibrationmode = "H3"
</eyetracker>

Thanks!!

Currently we only support animated gifs for calibration, unfortunately, but those gifs should work.

What version of Inquisit Lab are you running (see About Inquisit command), and is it on Mac or Windows?

Do they work with other calibration patterns (e.g., HV5)?

I tried a single gif in HV5 using the video element (and multiple gifs) and neither worked (still gets stuck on "Finished loading script"). I have Inquisit 5.0.13..0 64bit (build 4240) and the computer is a Mac.

Hi- thanks for the quick reply! Tried these both and they both freeze the loading process. It gets stuck at "Finished loading script" and I have to force quit.

I also tried this with a single gif by loading a gif into the video element with the same result.

BTW, validation always succeeds.

For a video calibration stimulus, something like

<eyetracker>
/ plugin = "srresearch"
/ aoidurationthreshold = 2000
/ calibrationstimulus = "somevideo.mp4"
/ calibrationmode = "H3"
</eyetracker>

or

<eyetracker>
/ plugin = "srresearch"
/ aoidurationthreshold = 2000
/ calibrationstimulus = "myvideo"
/ calibrationmode = "H3"
</eyetracker>

<video myvideo>
/ items = ("somevideo.mp4")
</video>

should work, I believe.
