Presenting pictures at variable locations


I’m trying to get my photos to appear at random locations on the screen. I clicked on ‘Variable’, but what does 'Screen Location I and II" mean? Then why does it ask you to select a specific corner of the screen? When I did this, I lost the variation.

Does anyone have any suggestions. I’d really appreciate them.



Screen Location I and II are are Trial Variables, which is found under the Experiment menu. Double click on Screen Location I, rename it, and then create your locations on the screen. Now, when you are in Settings, you can choose Variable and then select the screen location name you created. If you use the screen location trial variable, then the option below (the grid where you can select screen location) will not apply.

thanks for your help:)
