What are you trying to achieve?: I am trying to make a Psychomotor Vigilance Task (PVT). I want to have a video of a driving scene playing continuously in the background while polygons appear at random intervals for participants to respond to.
Here is the sequence I am trying to achieve:
- video playing in background
- dot to appear in the middle of the screen
- participant responds with RT recorded, dot disappears on key input
- between 5-10 seconds following that dot disappearing, another dot appears
(repeat 2-4 for the duration of the video / about 15 minutes)
I can get the video to play and understand how to use the key input to make the polygon disappear and record RT, but am unsure on how to make the polygons appear at random intervals without interrupting the background video or changing the routine/loop.
Any thoughts or suggestions on how to set up the polygon?? THANK YOU!!!
