Virtual Scroll bar is a feature which enables you to operate scroll action with one hand in applications such as browsers or PDFs.
There are 2 types of Virtual Scroll bar, vertical scroll and horizontal scroll, which you can define according to your needs.
When you want to display the virtual scroll bar,stop your palm of the hand at that point and move your palm of the hand up or down to scroll vertically,move right or left to scroll horizontally.
By default, you can use this feature in the browser and Acrobat Reader.
How to use the feature
1. Stop your hand on the window of the corresponding application.
2. The virtual scroll bar will be displayed.
( According to the position,the top/bottom bar may not be displayed)
3. When you move your palm of the hand up/down, the screen will be scrolled.
4. When you move your palm of the hand far from the virtual scroll bar, it will disappear. Depending on the distance from the center if the scroll bar, the scroll speed will change.
Operation tips: You can disable the display of virtual buttons and virtual cursors in the following situations.
1. When no operation is executed for 3 seconds after the virtual cursor is displayed
2. When the virtual cursor is moved to a position very far from the virtual button
Once the virtual button display is disabled, even if you move your palm and stop, the virtual button will not be displayed. You have to disable the display of the virtual cursor by moving your palm outside the camera sight, and then start operation. This feature is designed to avoid the display of the virtual button each time you stop your palm so that it won't interfere the operation.
When to change the application you are operating, the virtual button display will be valid again.

Default settings of Virtual scroll bar for browser are defined as shown below. Important: The row of valid coordinates definition should be written before the action row.
(10,10)-(300,240) on the second row defines the area which the display of virtual scroll bar is valid. In this case, almost all of the screen is valid. Valid area is calculated by setting the whole screen as 320x240. This is useful when displaying in a specific area of the screen.
Define valid area according to the application window size
When putting a F at the first of the definition row, valid area will be dynamically calculated according to the application window size. Valid area is calculated by setting the application window as 320x240. This is useful when displaying in a specific area of the screen.
The following examples shows virtual scroll bars on both sides of Chrome being displayed. Even if the window size of Chrome changes, the bars will continue to be displayed on both sides.
Enable multiple virtual scroll bars
To define and use multiple virtual scroll bars with specified areas within the same application, define several combinations of the application name and the virtual scroll bar.
After you define multiple virtual scroll bars, give the button names such as "zoom" which will be displayed with the virtual scroll bar.This will help you to distinguish what the sets are and what they do.
The following example is Google Earth opened in Chrome. It shows the virtual scroll bar for zoom on the left and another scroll bar on the bottom for right/left rotation.
Supplementary information: You can define a maximum of 4 scroll buttons for a single window.
Enable Display virtual button area option in Advanced Settings tab to display the defined area of the virtual scroll bar.
It will be displayed when your palm enters the defined area for the virtual scroll bar.
It will also be displayed when switching applications; displaying all areas of the virtual mouse button (virtual scroll bar, virtual button, virtual mouse).
Example: In Google Earth for Chrome that is included in the sample, you can see areas where virtual buttons are set in the image shown below.
