This article explains how to define a touch zone in the Elo Windows driver

Please note that if the video rotation is desired, defining Touch zones should be done after the video rotation is done.
This utility allows the user to define certain areas, or “touch zones”, on the display, where touch is either enabled or disabled. The user can define a maximum of 64 zones for a single touch screen.


To define a touch zone:

Click the “Define Touch Zones” button. Two dialog boxes will be brought up:

• The dialog box titled “EloTouchZones” provides options for setting a touch zone and allows users to delete existing touch zones.
• The other dialog box, which does not have a title bar, will be used to define a new touch zone.
• Users can drag this second box to any touch screen and adjust its size and position.

• It may be specified in the “EloTouchZones” dialog box whether touch will be enabled “inside” or “outside” the zone. If the user chooses to have touch enabled “inside zone”, touch will only work within each defined touch zone. Touch will be disabled outside of all touch zones.
• To save the zone, click “Save Zone” from the “EloTouchZones” dialog box.

To test the touch zone(s):

• Click the “Test All Zones” button in the “EloTouchZones” dialog box. This will test all defined zones with the current changes.
• Test mode will last 15 seconds. During the 15 second period, the “EloTouchZones” dialog box will be disabled and will not respond to any user input.
• After the 15 seconds, test mode will exit, and the user can continue to define new zones or remove existing zones.

To define additional zones:

• Drag the second box with no title bar to a new position on the desired display and adjust it to a desired size.
• Click “Save Zone” on the “EloTouchZones” dialog box.
• Any previously defined touch zone will be shown as a flashing, dashed rectangle.

To delete an existing zone:

1. To remove a single zone, drag the second box with no title bar to the desired display, click the “Selected Zone” radio button in the “Remove Zones” group. Select the number of the unwanted zone in the list box, then click “Remove”.
2. To remove all zones and allow touch to be enabled on the entire desktop, select the “All Zones” radio button. Then, click the “Remove” button.
