Have you considered DMDX from the Univ. of Arizona

It is a rather capable program, runs on Windows platforms, and may help
you with your situation.


| Dear all!

| So I need to use a free software for my experiment if I don't want to

| Did anyone ever try to do presentation of visual stimuli (images,
| practically, with a little bit of text in my case) with R? I looked

| I saw) the possibility to also read (unbuffered) keyboard input.
| So what I need is:
|   1. put images onto the (full!)screen (qick)
|   2. read keyboard input
|   3. write results (to an R structure, presumably)
| Any idea, suggestion?
| Cheers,
