The monitor has touch capability due to a touch-sensitive screen installed. A touch
screen is an input device just like a mouse or a keyboard, and the user’s hand
transmits position information via the touch screen to the computer. With this
technology, you only need to touch the pictures or words on the computer display
lightly with your finger, and the computer will react.
2.1 Touch Screen Calibration

are touching it, start the calibration program. The procedure is as follows:

2. In Control Panel, select “Hardware and Sound”.
3. In “Hardware and Sound” window, select “Tablet PC Settings”.

movement recognition method, which only needs the finger to move lightly on the
computer display screen or make a simple hand gesture to be detected by the
main computer processor.

operation.

times, to perform a single click or double click operation. This is similar to the
action performed by clicking the left mouse button.
