A Virtual Tablet adjusts the position of the cursor by moving it to a specific location on the screen. The virtual tablet may have optional Barrel Switch and Eraser buttons.
A virtual tablet must also be configured with coordinates that define the minimum X-Axis and Y-Axis values that its building blocks are expected to receive. The Left coordinate will map to the left side of the main screen, the Right coordinate will map to the right side of the main screen, and so forth. In most cases, the dimensions of the main screen should be used for the virtual tablet.
