Touch response coordinates
First of all, I'm loving the experiment builder! I'm an absolute newbie still, but the idea of running experiments on a tablet opens up so many possibilities, and I'm definitely excited to try!
One question I have is whether it is possible to get the coordinates of a touch response in pixel space (or close to it). As I understand it, Open Sesame allows to divide the screen into rows and columns so that each resulting region has its own discrete identifier. However, for an experiment I am trying to build, I would need the location of the response to be as continuous as possible, in order to then calculate the angle between the touch location and another point on the screen. I know that detecting locations on a touchscreen is by necessity a matter of approximation to an extent, but I was wondering if Open Sesame would allow me to do this within the accuracy limits of the hardware itself.
I hope this makes sense. I probably shouldn't try to explain myself after midnight.
