Can a projected capacitive screen be electronically controlled from outside?

Question

iPhone

Apple puts a wiki in its devices: Projection-capacitive touch screens and buying such a long time is not a problem on the same ali-express.
Question! Are there similar devices, but working in the opposite direction? A la overhead film or something similar to control this very screen electronically from the outside world. You glue the film on the phone, connect its cable and controller to the PC via the same USB, and then programmatically send Tap or Swipe commands, and the film, changing the capacity in the desired coordinates, emulates finger pressing.

Answer 1

technically this can be done.
for example, in the form of a thick board. on the side adjacent to the screen is a matrix of pads. on the reverse side is a set of kmop keys that close the indicated sites to the ground, plus a control matrix for these keys.
to simulate a "finger", the necessary sites are shorted to the ground.
the film is thin, a thick board will greatly distance a bunch of conductors of the control circuit from the smartphone screen and will not “flash” on the screen.
