problem with the background


currently, I´m working with opensesame to produce an experiment for virtual reality glasses (VR-glasses) and I have a problem with the background. Actually, my background is white. I would like to change it to a picture or a video sequence in the background and the introduction (text) in the foreground. Is that possible? Above that, is it possible to blur the background (photo or video sequence)?

Thank you :-).


  • Hi,

    You don't need to treat the background any different than a screen wide box. In this sense, just put whatever you want participants to see on a canvas and show it. If you add something (like text), you can just draw it on top of it. It is a little more cumbersome that using the actual background keyword, but it does the trick.
