These two layers are separated by separators and placed a layer scratchproof full installation. An electric current runs through the two layers while the monitor is operating. These two layers of screens make electrical contact when the user touches the screen. This allows the team to calculate the point of contact on the screen by the electric field generated by the contact. The team calculates the coordinates of the point of contact allowing the translation of the coordinates in a language that the computer can understand.
A surface acoustic wave system monitor consists of two transducers placed in x and and axis of the computer monitor. These transducers sent sound waves mutually and instantly recognize any disturbance in the system when he played as well locate the place where the contact was made.
