Eye tracker and simpletime problems

Hi all,
I’m building an experiment with “the eye tribe” eye tracker. In the output file I have the records of a fixation point every 33.33 ms (sampletime), but for my experiment I need to increase the milliseconds (in order to have more observations). Is this possible with this eye tracker? How can I change the default sampletime on OpenSesame?
Thanks for the help,



  • HI Silvia,

    According to this paper you can increase the sampling rate to 60 Hz and get samples every 16.7 ms. However, 1ms precision is not possible with the eye tribe. Unfortunately, I don't use the eye tribe myself, so I can't tell how to adjust the sampling rate.

    Good luck,
