Resolution (w/h):
Please enter here the resolution of your monitor (w=width, h=height) where the WD runs on. This is needed to adopt the positions of the detected touch points to fit to your screen.

Inv X:
Check "Inv X" if you need to invert the X axis.

Inv Y:
Check "Inv Y" if you need to invert the Y axis.

Swap:
Check "Swap" if you need to swap the X and Y axis, e.g. when the camera is turned about 90°.

TUIO:
In order to output multi touch data to other applications this option allows to send the Camera Point Tracker's multi touch data via the open source protocol TUIO.
This protocol is widely used around the world by many application developers and is a commonly known way to transmit the individual touches.
To use Camera Point Tracker with TUIO, set up the TUIO host IP and Port in the Connection Manager.

x/y/w/h (Range Conversion for Touch points):
The range conversion for touch points can be used if the camera point tracker should only affect a specific screen region, or if multiple Widgets are used with multiple camera point trackers together.
Enter the position of the region's starting pixel (left top pixel) inside the text fields for x and y.
The regions size will be defined by entering its width (w) and height (h).

Example:

In the image above a point is tracked (point 1) in the center of the camera point tracking tool.

In the images below you see the usage of this touch point in a Multitouch Panel with different range conversion setups.

Image 1: There is no range conversion setup in the camera tracking tool. The point that is detected in the center of the camera image appears in the center of the Multitouch Panel.

Image 2: There is a range conversion setup in the camera tracking tool. The region defined is shown by the red dashed rectangle. The point that is detected in the center of the camera image appears now in the center of the defined region instead of appearing in the center of the whole panel.
