I want you to create android application in unity.
This app must react to camera live view - when tip of the finger (or part of hand) cross virtual square (fixed onscreen - to screen, not environment), program must give response in code - (1/0 or letter).
Also the square must be adjustable for me (i have to know how to change size, psition etc.)
I want to develop this app further for security and i want to know how it works and how to change it.
