The driver is configured in MacOS as follows. A codeless.kext file (tbupddmxhid.kext) is used to specify the hardware. This file contains the list of USB vendor and product ids supported by the driver. Its purpose to register the driver for the supported USB device (s) so that UPDD can take control. This also prevents HID taking control of HID devices to be supported by UPDD.
Download the UPDD TUIO server that is appropriate for your OS and your version of the UPDD driver. For example, we downloaded and installed the software for Max OS X, for the UPDD driver version 5.1.1443. Blackberry users guide. If you want to specify an alternative TUIO port or start the application from the command line, just type: java -jar TuioMouse.jar [port] (substitute with the desired UDP port number) TuioMouse will use the first available TuioCursor as the principal mouse pointer.
The driver uses TCP/IP port 4146 to communicate between components using the API. Interface The driver uses a number of to post co-ordinate data into the system: Interface Type Description Simpletouch Single touch mouse interface Default interface that offers a basic touch interface as implemented by the driver itself. In a Mac OS X environment the older IOHID interface is used to post ‘mouse’ messages into the system. Uses an old API that may be deprecated in future releases of MacOS. Simpletouch_cg Single touch mouse interface Alternative interface that offers a basic touch interface as implemented by the driver itself.
In a Mac OS X environment the newer core graphics interface is used to post ‘mouse’ messages into the system. Gestures Multi-touch gesture interface Interfaces with the gesture capability of the Mac OS system and gesture aware applications. This is particularly useful for dual and multi-touch touch devices as it allows common gestures to be performed via the touch screen. When gestures is loaded its interface into the system will take precedence over the simpletouch interface. If gestures is quit the simpletouch interface becomes active.
Processes In normal circumstances once installation has completed there will be a number of processes running. The actual number will be dependent on the installed components held in the installer.
The core driver utilises two processes updd (the user mode driver service) and updd daemon (the background task). If gestures and/or TUIO server is installed these applications will also be running. Some transitional applications, like the UPDD Test, Calibration and Identify will be listed in the Activity Monitor when they are running.

However, some core UPDD applications will be permanently listed once they are running: Process Purpose UPDD The driver and the API interface. UPDD Daemon The driver's daemon task offering a number functions relating to the driver and user interface.
UPDD Gestures Offers full MacOS gesture support and gesture API interface. UPDD TUIO The UPDD TUIO server that reads co-ordinated data from the driver and broadcasts it to and waiting TUIO client application. Stopping and starting UPDD processes In some cases an end user may wish to start / stop UPDD related processes such that they are only running when required. To allow for this we have created a python script, named upddprocesses, which can be used to start and stop the various processes. The script must be run under root (precede the command with sudo - password will be required). It can be used from the command line, a script, or process by executing it thusly: [sudo] upddprocesses start [sudo] upddprocesses stop It can also be used as a python module in another python script.
