Electrical – touch screen foil behind 5mm thick glass


I wish to make a small project that will enable me to control my tablet\ipad behind my shower glass door.
I want to be able to put the tablet behind the glass and control it from the other side of the glass door.

I though about connecting a capacitive touch foil to the tablet and placing it between the glass and the tablet so the capacitivity should work.
I also though about connecting a lcd screen with an overlay touch foil and using otg or mhl for connecting it to the tablet.

What do you think would be a good way of implementing it and how ?

Thanks a lot

I'm not convinced that would even work. A capacitive touch screen depends on the "finger side" of the screen not being conducting laterally, and soapy water is a pretty good conductor. Much like a V.I.C.E. (Vegetable Interface Contact Entities):
