Hello,

I was wondering how to create an experiment that presents images pairwise on the screen, together with a questions (e.g. Which face do you think is more attractive?).

Is there a way that the subjects can click on the images for providing their statements (or at least on buttons below the images)? Could the faces be randomly chosen from a certain "images" folder, or do I need to create maps with all combinations of pairs in an imaging program (or Powerpoint) and tell Medialab to randomize these maps/slides?

Any experiences and/or suggestions about how to figure out such "forced choice" design will be highly acknowledged!
