[solved] mouse coordinates with a touchscreen
Hi everybody,
I am new to opensesame and new to this forum. I am developping a pointing task using a touchscreen and try to get the finger position using the mouse inputs. I already found outstanding help on this forum but I still have some troubles. Using inline scripts or the mouse response item, I get different coordinates if I allow the cursor to be visible or not. When pointing to the center of the screen, it seems that the coordinates are correct only when the cursor is visible. Obviously I would prefer to hide the mouse cursor during the experiment. Any idea about that?
Thank you very much.

Hi Patrice,
As per great coincidence, I've been working on a task for a tablet-pc (an Asus B121 running Windows 7) today as well. What I found is that using PyGame my mouse coordinates were really messed up (it seemed like only a little window within the entire display was recognized as the entire display), but when using PsychoPy this problem wasn't there.
I have to admit that this wasn't using OpenSesame, but I do not expect OpenSesame to behave any different. Therefore you might want to try different back-ends (especially the psycho back-end) to see if that fixes your problem.
Mouse visibility is something I haven't tested, by the way. Might be something to try out as well for my task (so thanks for that tip!).
Good luck!

Hi Edwin,
Thank you for the advice. It works much better with the PsychoPy back-end.

That's great! I'll mark this as solved.
