• The crazy thing is that the recordings I shared are all of me, doing the same thing without moving the tracker or head mount. I am still not sure what's going on, but I'll update here if I find a cause

• Thanks Josh. Participants are allowed to blink naturally, however the signal we are receiving is clearly unnatural. Here is an example graphed with plotly: https://plot.ly/~tsummer2/57/raw-x/ Each time series represents a separate recordings of the …

• We are using the EyeTribe. During the experiment, the participant uses a chin rest while they perform a go/no go task. We are primarily interested baseline pupil size before each stimulus presentation. We are relatively new to python and pupil da…

• Hi Matt, You are going to have to be more specific, which part of your task would you like help with?

• Hi mordurx, Are you using the EyeTribe? So far it doesn't seem like the eyetribe actually uses eye_used. The only function that references eye_used for the EyeTribe is in the libeyetribe.py in the comments... When the function is actually called it…

• Guido, I have noticed a similar problem in my own experiments. At one point, I did essentially what Sebastian suggested above but I used a sleep time of 5000ms. I measured the time between my logged events, and took the difference between them to g…

• After I ran another experiment, I think you are right. But I am still getting a jitter... my monitor has a refresh rate of 60Hz, which is one cycle every 16.66666 milliseconds. That means to "catch the train" I would have to use a delay ti…

  in EyeTribe & PyGaze Log Timing Accuracy/Precision Comment by tsummer2 December 2016
• Sure thing, I will try that next. I guess I was just assuming that the refresh rate of the monitor is only important for timing when a stimulus was being presented. So since I didn't present any stimuli I figured it shouldn't matter. I hope you are …

• Sorry Eduard, I meant to remove this post. I still couldn't figure it out so I had opted to just replace the form with a keypress instead. I have since saved over the previous version of the task so I am unable to share it. It was strange because it…

  in Mouse disappears during form presentation Comment by tsummer2 November 2016
• Hey Eduard, It seems like the only thing I should take into consideration for variable timing would be time between loops, but don't use one. The for loop described above occurs in one inline script in a sequence. So it seems like that shouldn't be…

• Hi Daniele, I am glad you figured it out. I thought I would still share what I know about the timestamp because I am still trying to understand it myself. The correction seems to be necessary because the EyeTribe has its own clock which it uses to r…

• I figured it out. The _exec function of a form has an argument for determining which widget to focus on. By default it is None. Here is the code for selecting my text_input widget when the form is loaded: execform = form._exec(focus_widget=textbox)
