Hi all,<br><br>I would like to know if it is possible to create gaze contingent paradigms with e-prime/tobii extension for eyetracking studies. <br>In a feature overview of the e-prime extensions for tobii I read that it would be possible to start and stop trials contingent on eye gaze, fixation, or eye movement criterion. In the PST user forum I read something about a sliding windows script for e-prime but in combination with a different eyetracking system, I guess. <br><br>What I would like to do with e-prime/tobii extension is:<br>- to start and stop a presentation of a stimulus contingent with a specific number of fixations/amount of fixation time or contingent with a saccade’s beginning/ending or the landing of a fixation respectively. <br>- move a stimulus contingent with the eye gaze, so that the subject can’t change its fixation position while it is moving its eyes. <br><br>Has anybody experience with that? Or can tell me where I should look to figure it out? <br><br>Thank you in advance for any help you can provide. <br><br> Jonas<br>
<p></p>
