eye tracking & e-prime2

[Michiel Spape]

Hi Jan (is that Jan-Rouke? How are you?),
If a) your experiment works in E-Prime 1 (with e-prime extensions for Tobii), then, when importing the whole thing to E-Prime 2, it doesn't anymore, I'd also suspect there's something wrong with the E-Prime 2-TET-package integration, probably best sorted by contacting the Tobii people. Certainly, b) if it crashes even with just StartTracking (which is required anyway), there's no reason to think that video as such is the problem. So, it's a long shot, but have you tried updating your TET packages?

And yes, as for my earlier suggestion, there's software out there (virtualdub, http://www.virtualdub.org/blog/pivot/entry.php?id=34) to make your life easier. That is, exporting .avi at 25 Hz (or whatever framerate they are) writing out [originalname number], then making a loop over "number" with images showing every 40 ms, is pretty easy to accomplish, I should think (especially if you won't care about the occasional tearing). 

Best,
Mich

Hi all,

I was wondering whether any of you has had trouble with getting the
TET server working (e-prime extentions for Tobii) with e-prime 2. I
have, for a while, a nice setup working in e-prime1 but I need to
display movies now. I noticed Michiel suggested in another discussion
to use frames in e-prime 1 instead of movies, but I do not want to
resort to that just yet.
Now, Clearview is working in e-prime2, also I can open/connect TET but
when any other comminication is required (TrackStatus, StartTracking)
it crashes (no message why). So maybe there is a bug in the TET
program (the sample of e-prime does not work either) just as was the
case with earlier versions of the package for e-prime 1 (Clearvier and
TET would not work in te same experiment, to be sorted by disabling
the sentence Const DEVICE_CLOSED = 0 in one of the packages).
Anyway, I have been at it for 2 days now and it is getting on my
nerves.

Thanks!

Jan
