Zoom:
Use the zoom factor to zoom in / out the AirScan field.

Multi Point Mode:
The Multi Point Mode is checked by default, it allows to detect up to 24 points. With this mode the performance and precision of point detection is enhanced compared to the previous detection mode (that only allowed to detect two points).

To use the multi-point read-out for further processing, please use the AirScan Multi-Point Input Node.

When not using the Multi Point Mode, please use the AirScan Input Node for further processing.

Damping:
As you can see in the AirScan setup tool there is also a damping filter value. This value is important as the IR readout of the AirScan can have noticeable noise that is filtered out with this prediction based damping.

The damping factor is set by default to 0,10. You can change this setting from 0,1 = maximum damping up to 1 = no damping.

Motion:
The Dynamic Motion Damping improves the stability of the touch point in motion and stabilizes the points when they are not moving. It is set by default to 0,3. Its value ranges from 0 (max. smoothness) to 1 (no motion filtering).

Resolution:
Enter here the resolution of your Widget Designer GUI (width and height).

Range:
The Range is defined through n (near field) and f (far field) in mm.
Beyond this range no AirScan position data will be transferred to the Widget Designer. Please be sure that the Active Field (the white rectangle) is positioned within the near and far field.

Active Region:
X&Y - The coordinates x and y define the position of the Active Region in relation to the AirScan's position in mm. Please enter the size of the region for W (Width) and H (Height) in mm.

W&H - Enter here the size of the Active Region (width and height) in mm.

Safe Region:
The Safe Region makes the detection of points on the border of the active region more robust.
Enter values in mm for X&Y, ideally the Safe Region is a bit bigger than the Active Region.

Processing (only used when the older mode for only 2 point detection is chosen):
t (Threshold) is equivalent to the angle-ray-count to the distance between point 1 and 2.
ct (count) is the maximum ray count per point.

Inv X / Inv Y / Swap
Use these options if the AirScan is not located above the active field.
If the AirScan position is e.g. below the active field, check Inv Y to receive correct Y Position data.
