Touch screen instructions This chapter contains the following topics: Touch Screen Calibration User Gesture Instructions for the Touch screen Attentions when using the Touch Screen User Guide 15
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.
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. 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.
3. 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. 4. 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.
5. 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 in (or zoom out) operation. For example: you can enlarge or reduce the picture size in Windows Photo Viewer. 6. Rotation Operation Use two figures to touch the desired item on the touch screen, then rotate them in the desired direction.
Related Touch Screen Settings • Select Hardware and Sound → Pen and Touch from the Settings charm. • Select touch actions which you wish to adjust. By clicking on “Settings”, you can adjust the “Speed” and “Spatial tolerance” parameters, to match the user’s natural way of double-clicking. You can double-click on the lower right corner of the icon to test this. Note: Users can access more help information from the Windows Help and Support menu.
Precautions when using the Touch Screen 1. When using the touch screen, be careful not to tear the surface with any sharp objects. 2. To ensure normal use of the touch screen, ensure that both the screen surface and your fingers are clean and dry. 3. To ensure precise positioning on the touch screen, avoid handling or touching the glass frame when you are touching the screen. 4. Turn the computer off for safety before cleaning the screen and frame with a soft cotton cloth.
7. The touch screen does not function in Rescue System mode. 8. The touch screen also does not function during the startup process, in Hibernate mode and in Sleep mode or Safe mode.
