Place image on screen (case 4954)

[mikefinn]

Hi all,

I am developing an experiment where participants will view a series images on a touch screen monitor (lying face-up on a table) and are subsequently asked to place images where they remembered seeing them. I would like for this placement phase to consist of physically moving images on the screen one at a time.

Any ideas about how to get medialab to allow for a 'click-and-drag' type measure? I don't know where to start. Reaction time and screen placement are my desired datapoints.

In case this makes things wildly easier, I'm only interested in a 1-dimensional measure of location on the screen.

Thanks,
Mike
