The Multi Point Mode is used by default unless you disable this function in the Input Point Processing.

Points:
Enter here the amount of points that should be detected and provided for further processing.

Point ID Offset:
The Point ID Offset should be used when you are sending the Multitouch data from this AirScan via the Remote Input to another Widget Designer. It avoids that the Multitouch points from several data inputs get the same IDs and that there are any ID conflicts.

Trim:
Trim allows to minimize errors on Point enter, with this value a number of scans will be ignored until the point motion processing is activated. The default value for Trim is 0.

VCount (Validation Count)
The Validation Count defines the amount of rays that have to be interrupted in order to validate a touch point. The default value is 2.

Gap:
The default value for the Gap is 5. This means that within 5 rays distance of a detected point all other interrupts will be discarded.

Max Delta:
The default value for Max Delta is 100. The Max Delta function determines the maximum speed for Multi touch Point Tracking.
X&Y Offset:

These offsets allow to run the Widget Designer on a secondary screen. If you’re doing so please enter here the pixel offset for x and y.

Example: resolution of primary and secondary screen is 1024x768, WD runs on the secondary screen, enter x=1025 and y=0.

Start Ray:
The AirScan sends out 500 Rays over 180° clockwise. If you want to discard rays up from the start, enter the new value here (0-499).

Stop Ray:
The AirScan sends out 500 Rays over 180° clockwise. If you want to discard more or less rays, enter the new value here (0-499).

Range: (Touch point offset):
The Point offset for the Multi-Point mode allows running the WD on a secondary screen.

TUIO:
In order to output multi touch data to other applications this option allows to send the AirScan’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 AirScan with TUIO, set up the TUIO host IP and Port in the Connection Manager.

INFO:
Enable this check box to show the Point Read-Out Dialog with the data of all multi touch points.
