I want to simulate a finger touch/move/etc. on capactive touch screen. Obviously using a robot arm and stylus pen is a solution, but it was expansive and the structure was too complex. It would be elegant if we can lay something (another capactive touch screen) on the original screen and drive it to simulate a finger.
I learned that a capactive touch screen is somewhat a row/column selection capacity matrix. So is it possible to make a driver system to activite certain areas in the screen and make it recognized as a finger touch?
The problem want to simulate a static touch area, but I want a CONTROLLABLE/PROGRAMMABLE activition of ANY area in the screen.
