Present an image and continue the experiment pressing certain key (case 19659)

[machukas]

Hi and thanks in advance.

I?m doing an experiment and i want to: present an image to the user, only that, and then the user knows that he can choose to press a couple of keys (i.e. a road with an intersection). Now i want to be able to, when the user presses one of the two possible keys, go to the next quest and save the pressed key.

I have tried with multiple response item type, setting the image in the background, but the responses text field (like 1, 2 or a, b, etc) are showing in the foreground distracting the users attention of the image. I've also tried with image file item type but i don't know how to go to the next quest and save the key without using the space bar.

Did anyone do this before in a simple way?

Thanks!
