Multiple sound files and multiple video files (one at random per trial).
I am creating a visual perception experiment and need to include multiple sound/video files.
In brief, within each trial participants will:
1. See a fixation dot.
2. Hear one of two sound files.
3. See one video randomly selected from a pool of videos of hand movements. The video will disappear once the hand finishes its movement.
4. Provide a touch screen response on where the perceived final location of the hand was. The level of perceptual bias is measured through the difference of the actual coordinates of the hand vs the touchscreen response coordinates.
I am still learning OpenSesame (basically a novice) and I am having trouble setting up my experiment to choose one of multiple files at random, both for the sound and video files. I also need to define where the actual coordinates of the finishing point is, so that the difference to participant responses can be calculated.
I'm sure there is a simple way to do this, but all the online tutorials seem to be slightly 'off' what I'm trying to achieve and our tech team simply don't know the programme enough to help.
Any help someone can provide is greatly appreciated!
