Hi there, I actually concatenated two experiments together: First I test participants’ screen parameters and then I do the formal experiment which was built on psychopy3.
By editing the html document (adding first part’s code to the psychopy3-generated “index.html”), now I can successfully run the whole experiment on pavlovia.org.
But I want to customize the location of the stimulus based on the screen parameters I tested before. For each participant’s screen size, resolution, and viewing distance may be different, so it’s not possible to present stimulus using “height” or “normal” unit while keeping the visual angle consistent among participants. I think it’s possible to present my stimulus in “pix”, the values(how many pixels) can be calculated based on those parameters.
Description of the problem:
That means I need to get access to the stimulus parameters like presented locations(imported from conditions.xlsx) on “main.js” and then revise them according to parameters tested before. How can I do that?
Thank you very much!!!
