Touch screen instructions
User Guide 11
This chapter contains the following
topics:
ØTouch Screen Calibration
ØUser Gesture Instructions for the Touch screen
ØAttentions when using the Touch Screen

12 User Guide
The monitor is touch-sensitive thanks to its touch-sensitive screen. A touch screen
is an input device just like a mouse or a keyboard, and the user’s fingers transmit
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
Prior to first use or whenever the touch screen reacts in a different place where you
are touching it, start the calibration program. The procedure is as follows:
1. In Windows 7, Select “Start” – “Control Panel”.
2. In Control Panel, select “Hardware and Sound”.
3. In “Hardware and Sound” window, select “Tablet PC Settings”.
4. In “Tablet PC Settings” dialogue, click “Calibrate” button.
2.2 User Gesture Instructions for the Touch screen
The Touch screen supports single touch 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 very low 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.
2.2.1 Basic Hand Gestures
1. Single Click / Double Click
For the item selected on the touch screen, with one finger touch it one or two
times, to perform a single click or double click operation. This is similar to the
action performed by clicking the mouse left button.

13
User Guide
2. Single Finger Right Click
For the item selected on the touch screen, press and hold your finger on the
screen until a circle appears. After lifting your finger from the touch screen, a menu
bar will pop up, completing the single finger right click operation. This is similar to
the action performed by clicking the mouse right button.

14 User Guide
3. Double Finger Right Click
First touch a finger to the screen to select the desired item and hold it there, then
touch another finger anywhere nearby on the screen and quickly lift it up again,
to complete a double finger right click operation. The area where the first finger is
placed can be used to show the right-click menu or perform related operations.
12
4. Dragging Movement
First touch your finger on the desired item on the screen and hold it there, then
make a dragging movement. This is similar to the click and drag movement you
can make with a mouse.
