<div>Slide duration of 300.000 will cause E-Prime to wait for eternity'ish before actually checking whether somebody is fixating or not! Definitely not suggested.</div>
I believe the Tobii E-Prime Extensions documentation covers this very explicitly. Basically, the slide should be 0 ms (so that it refreshes continuously) with a TETWaitForFixation (or something of the sort) after this. In the properties of this package-call,
you set 1500 ms, which means E-Prime will only continue if the person is fixating (without interruption!) for 1500 ms. This, in turn, I believe is internally done with simulating key-presses. The tutorial on Tobii Extensions for E-Prime is something you should
definitely not skip (I did, so do like i say, not like i do - i regretted it anyway!)</div>

<div>Could you do it via slide duration? Perhaps you could make the slide duration very long (like say, 300000 ms).<br>
<br>
Then you could write an if statement that says if looking = 1500 ms, then slide.duration = 300000<br>

Hi,<br>
<br>
I would like to end the slide when the looking (using TOBII) reaches<br>
1500ms. I have all the code to calculate the accumulated looking, but<br>
do not know how to terminate the slide once the accumulated looking is<br>
reached. Is there something like Slide.terminate to end the slide? Or<br>
is there a way to simulate key press when the 1500ms is reached, so<br>
that I can simulate the key press within the code of accumulated<br>
looking and terminate the trial on keypress?<br>
<br>
Thanks<br>
Sravani<br>
