Hi,
in my experience, in studio and on stage, my Pa1X touch works fine.
I saw a lot of new applications of the touch in the real world like:
- ticket point at the railway station,
- bancomat
- info point at museums, fairs, etc.
This seems a good feedback to understand how this technology looks intuitive and foolproof. If this has never happened you will never had applications like the mentioned before, that is targeted to really different people around the world.
The only counterpart (see also another topic) is problems that arise for visually impaired or blind people: I saw a solution, with alternative keys around the touch screen, only in the case of bancomat, not for the other two (sorry).
Just my 0,01%.
Regards.
