This chapter explains the "Touch Output Processing" settings in the Camera Tracker in Widget Designer.
Resolution/ Range (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.
Check "Inv X" if you need to invert the X axis.
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).
Check "Inv Y" if you need to invert the Y axis.
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.
Check "Swap" if you need to swap the X and Y axis, e.g. when the camera is turned about 90°.
