Capacitive touch instead of IR

I have a 40" tv with an IR frame over the tv. I am finding it gets difficult to work with and overwhelmed when the minis are right next to each other. To the point I have had to reboot the touch program in the PI.

I am considering moving to a capacitive touch film or screen. Film is cheaper.

Has anyone done this recently? The information on the arkenforge website is old and out of date.

What did you find works for putting on the bottom of minis to work with the film/screen?
