inverted pointer movement in x-axis

[CarlosLopezMolina]

Hi Cesar, you did such a great job with EVA Facial Mouse.
As everything in this project is written in english I will keep using this language, for the benefit of the general users, although I'm spanish.

We are using it with ALS patients and find it really useful, a real enabler application. It worked smoothly in the smartphones we tested. The association I'm volunteering with, have several tablets of the model:
Woxter Tablet PC 98 IPS dual, con Android 4.1.1
The issue is that the movement of the pointer in the horizontal axis is just the opposite to the head movement, i.e. if I move my head to the left, the pointer moves to the right, just in the counterintuitive way.
If you need further information, just let me know. If you are interested in knowing in which models we tested, again, just let me know.
Thank you so much and best regards.

Hola Carlos,
Did you try with other devices apart from the Woxter tablets? Did you experience similar issues with other devices?
Could you please provide a short video in which appears the screen of the tablet while using EVA?
Best, C.
