2.2 User Gesture Instructions for the Touch screen

The Touch screen supports single touches and rotational movements, enlargement

and reduction multi-touch operations, and the user can transmit position

information to the computer via touch. The touch screen uses a non-pressure

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.

Note: The touch screen only allows the use of ﬁnger for touch screen

operation.
