Touch screen user instruction

This chapter contains the following

topics:

 Touch Screen Calibration

 User Gesture Instructions for the Touch screen

 Attentions when using the Touch Screen

Attention: Only some selected models are

equipped with touch screens.

User Guide 13

14 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.

15

User Guide

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.

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 left mouse button.

16 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 right mouse button.

17

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.

18 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.

19

User Guide

7. Zoom Operation

Touch two fingers lightly on the desired item on the touch screen, then keeping

both fingers on the screen, change the distance between them. By increasing (or

decreasing) the distance, you can perform a zoom out (or zoom in) operation. For

example: you can enlarge or reduce the picture size in Windows Photo Viewer.

8. Rotation Operation

Use two figures to touch the desired item on the touch screen, then rotate them

in the desired direction. For example: you can rotate the picture which is being

displayed in Windows Photo Viewer.

20 User Guide

2.2.2RelatedTouchScreenSettings

2.3 Attentions when using the Touch Screen

1. When using it please remember not to tear the screen surface with any sharp

object.

2. In order not to affect the normal use of the touch screen, please keep its

surface clean and dry, and ensure that your fingers are clean and dry.

3. In order not to affect the precision of positioning on the touch screen, please

avoid handling or touching the glass frame of the touch screen by your hands

when you are carrying out touching operations.

4. To ensure the safety of users, please clean the screen and frame with a soft

cotton cloth after turning the screen off. In order to prevent the remaining water

mark from affecting the touch operations, do not wipe it with a damp rag.

5. Do not place or drop anything which could obstruct it in the four corners of

the screen or any part of its frame, because this could separate the screen

from the frame and stop the screen from being able to sense position properly.

Please avoid leaving water and dust in the gap between the casing and glass

when you are cleaning the frame.

6. Avoid using it in dusty environments, or in very hot or humid conditions. The

abrupt change of environmental temprature may in a short time cause on the

glass screen inner surface some tiny spray, which will disappear after some

time and will not affect the normal use.

Note: When it is used in normal operation, the touch screen process will

not affect the running of other computer processes.

24 User Guide

7. The recognition of touch gestures by this product can be influenced by the

following factors:

• Touchingthecorrectplaceonthescreen.

• Thespeedofmovement.

• Thetimeintervalfromwhenthescreenwaslasttouched.

Note: To learn accurate hand gesture operations, the user can consult this

manual and also the related Windows help content.

8. The touch screen does not function in Rescue System mode.

9. The touch screen also does not function during the startup process, and in

Sleep mode or Safe mode.

10. The touch screen supports two-point touch only; if the touch screen is touched

more than two points while attempting a touch-operation, it will not work

properly.

11. While performing a touch screen operation, please avoid placing any metal or

conductive material on the screen.

Problem: The capacity of the hard disk, as indicated by the system, is less than

the nominal capacity.

Troubleshooting and problem resolution: For computers equipped with the

OneKey Recovery feature, the system recovery feature needs to occupy some

hard disk space. This may account for the apparent hard disk capacity deficit.

Further Technical Explanation: The nominal capacity of the hard disk is

expressed in the decimal system, 1000 bytes. But the actual hard disk capacity is

expressed in the binary system as 1024 bytes (For example, the nominal capacity

1G is 1000M, while the actual capacity 1G is 1024M).

The capacity of the hard disk shown in Windows can be calculated according to

the calculations in the following example:

The nominal capacity of the hard disk is 40G, while its actual capacity should

be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G.

If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x

1024) = 2.79G is subtracted, the capacity of the hard disk shown in the

system can be obtained.

The capacity of the hard disk as calculated using this method may be slightly

different from the actual capacity due to the rounding of totals.

5.5 Special considerations for troubleshooting Windows

Record the following information that may later be useful in troubleshooting system

problems:

1. The serial number of the software. The serial number was shipped with the

computer and was provided separately by the manufacturer. The Help Center is

unable to retrieve this number.

2. The drivers for this computer model only support the Windows 7 system.

3. When you use the Windows Media Center to watch TV, be particularly attentive

to the following:

• Inthefollowingtwosituations,youmustre-saveachannellist:

a. When you change your TV signal from digital to analog, your saved

channel list for digital TV is deleted. When you want to watch digital TV

again, you must create and save a new channel list.

b. When you change your TV signal from analog to digital, your saved

channel list for analog TV is deleted. When you want to watch analog TV

again, you must create and save a new channel list.
