◦ Multitouch View (Second Touch active) - The second touch is shown at the same axis of X or Y coordinates for reference for developers. Figure 5-8 Multitouch View - First and Second Touch active ● Fine Coordinate Correction - After you calibrate the touch screen, the Touch Point (2) and cursor should be located directly underneath your finger when you touch the screen. However, you may prefer to offset the Optical Point (1) or cursor slightly above your touch point so you can see the cursor and point more easily and precisely to small objects. The Touch Cursor Shift option lets you define the distance between your fingertip and the position of the cursor on the screen. Offsetting the cursor is helpful when selecting small items, such as single letters in word processing, check boxes, or radio buttons. Click [Up] [Down] [Left] [Right] to make X or Y offset. Click Reset to restore to default. Figure 5-9 Offsetting Optical Point (1) from Touch Point (2) Screen Shift Correction - It is possible for the screen image to extend beyond the edge of the monitor bezel.
