Hello mackrackit

I must design the "virtuall buttons" on the glass and the pcb is mounted behind, that is the problem than with normal capacitor sensor with the PIC
or Quantum IC's when a blind people scan with finger the area to find the desired buttons, validate all them, i need the same sensor technique but
validate only when make pressing on the glass.
Hope that with this explanation you can undestand what i mean
Sorry for my bad english

Regards
Pedro
