Saccade detection on Tobii trackers produces problems due to missing chin rest about pygaze

[scattenlaeufer]

Since we think this is a veritable problem in saccade detection on Tobii trackers it would be nice to get some feedback on this issue. It would also be nice to know, whether there is an interest to merge a reimplementation of the saccade detection into the master branch if we'd invest the work in doing it.

Sorry for the late reply; am in the final year of my PhD (aaaaah!), and December generally isn't me best month anyway :p

Thanks for the elaborate description of the issue. As you say, it's only a problem when chin rests aren't used. I don't have the time to spearhead a fix, but if you'd like to take it on, I'd be happy to help. Obviously, if you manage to solve the issue, I'd be very happy to include your code in the master branch!

Wondering if this was ever tackled? This might be problematic as Tobi tx300 and the Tobi pro spectrum dont use chin rest @esdalmajer @scattenlaeufer

@hcuve: @scattenlaeufer and I never tackled this issue as Pygaze fixation detection seems to be robust enough for a freely-moving head, at least for our goals. For offline data analysis, we have implemented an R version for our upcoming paper. If you are interested, contact me via PN.

Hi @arnohakk @scattenlaeufer

Thanks and sorry for not following up.

Would love to read the paper, is it available somewhere?

@hcuve Sorry for coming back this late. Our toolbox containing the code in currently in the review process. Are you still interested?

hi @arnohakk , yes please! Would love to read about your method, thanks!
