DReyeVR Parser data output #118

Closed Nitro60zeus closed 9 months ago

Nitro60zeus commented 1 year ago

Hi guys!

Um, so I ran the parser successfully. But there seem to be some issues.... The eye tracker works absolutely fine with DReyeVR. The output for gaze metrics and eye openess is missing. Here's the pic: image

But it seems to collect pupil diameter: image

Also, i assume the data is being collected correctly, because here it says 1 for valid: image

Looks like the data is there but the parser didn't get the data for the gaze data. Can you make sure this is parsed correctly? Try printing the element of the dictionary.

Nitro60zeus commented 1 year ago

So I tried printing the elements "LeftEyeOpenness" and "RightGaze". All values come out as 0.

Do you mind giving a look at the human readable file? Would be extremely helpful. ^^" file: a8.zip

Been trying to trouble shoot this, but i am not able to understand where exactly is the issue. Tried deleting and re-cloning the parser and started all over again, but still the same issue :/

Files (rec and txt): test23ax.zip

The DReyeVR_logging.py data looks absolutely great. Is there's any way we can use this or simplify to a more readable representation? File: test23.txt

Unfortunately this looks like a bug in the (DReyeVR) recorder rather than in the parser. Which is much more difficult to debug. I am away from a computer for a while and will be unable to debug for the time being. Hopefully you can use the raw logging variables for now.

Nitro60zeus commented 1 year ago

Oh, I see. No problem though, I am working out a way to use the raw logging variables to convert them into csv format. Should serve the purpose ig.

But yeah, thanks a lot man for helping all the way out, this far. Truly appreciate it <3

Hi I have kind of this issue. However I am in VR mode itshows the gaze and pupil zero!!! COULD YOU HELP ME image

Nitro60zeus commented 9 months ago

There are two ways you can visualize data.

1) Using DReyeVR parser: Make sure its calibrated well for the subject using it. If its not calibrated properly, such issues can occur. If it doesn't work, try deleting the parser and loading again.

2) Using DReyeVR_logging.py: This is great if you wish to manually play around with the data. The output I presume is in python dictionary format. So you need to find a way to convert into csv for manipulation.

Lemme know how it goes.

Thanks for replying. You mean the VR headset should be calibrate or something else. Also, when I execute DReyeVR_logging.py in anaconda prompt I just see some data and I do not know where the data was saved?

Nitro60zeus commented 9 months ago

Yeah, the headset eye calibration must be done. Also, make sure you are using x64 Native Tools CMD for the scripts. To see the data, you need to jot it down in a .txt file. Below, I have explained how:

DReyeVR_logging.py can be used in two ways:

1) When you are actively running simulation, you simultaneously start the script in another CMD window. For this you just run py DReyeVR_logging.py > log.txt in a cmd window.

2) You simultaneously start this script when you are playing a recording (.rec file). For this, you run the logging first, and the recording immediately after that in two separate cmd windows.

first this py DReyeVR_logging.py > log.txt and then this py show_recorded_file_info.py -a -f /PATH_TO_.rec file

The log.txt will appear in the same folder where the DReyeVR_logging.py script is present.
