Touch screen user instruction
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
Attention: Only some selected models are
equipped with touch screens.

12 User Guide
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
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, touch it one or two times with finger,
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.

15
User Guide
5. High Speed Slide
If you touch the screen with a single finger and slide it a short distance horizontally
(about 5 cm), then quickly lift it up again, this is called a High Speed Slide, and the
screen will show the “Forward” or “Back” icon.
In the default situation, a high speed horizontal sliding movement will execute a
forward or back operation. For example: Forward and Back operations for the
IE browser; or Previous and Next slide operations in Windows Photo Viewer
slideshow mode.
about 5 FP
6. Rolling Movement
When you move your finger one time vertically (or horizontally) on the touch screen,
this is called a Rolling Operation. For example: This operation is similar to moving
the scroll wheel on the top of a mouse, and produces the same results as the scroll
wheel interface does.
