General question about recording eye tracking data while using a software #13

Closed UBela closed 2 years ago

UBela commented 2 years ago

Hi, I recently started working with Titta and want to record ET data while using a specific software. From the demos I was under the impression that Titta needs a PsychoPy visual.Window in order to record data. My first guess was to create a transparent window in PsychoPy and use that as an overlay but I could not find a way to change the alpha value of a window. If it is possible to record data without the need for a visual.Window how can I safely close the calibration Window and start the recording process of the screen?

Hi,

Happy to hear that you found your way to Titta! Titta does not need a PsychoPy window to record data. After calibration, you can close the PsychoPy window (win.close) and then start the recording (look at the read_me.py demo)

Thanks, Marcus
