Setup the Screen
The Screens tab defines the digital coordinates mapped to your physical display.
- Go to the Screens tab and click Add.
- Select your layout shape:
- Rectangular Layout: Used for standard flat display walls, projections, and floors.
- Elliptical / Circular Layout: Used for round interactive tables or custom curved installations.
- Configure the dimensions:
- Size X (Width): Width of the physical touch screen area in millimeters.
- Size Y (Height): Height of the physical touch screen area in millimeters.
- Offset X / Y: Distance of the screen boundary relative to the sensor origin in millimeters.
IMPORTANT
Exact Measurements
To maintain high accuracy, measure the active area width and height precisely, and set these values to match the actual display surface size.
Configurable Areas
The Areas tab is used to limit or filter where touch points are recognized.
- Standard Setups: In typical configurations, simply click the Fit to Screen button. This automatically defines the active scan zone as the interior of your screen coordinates.
- Exclusion Zones: If the sensor's scanning path intercepts physical structures (such as doors, structural pillars, or structural AV framing) that create constant ghost touches, you can draw custom excluding areas over those positions. Touch coordinates inside excluding zones are ignored.
