[Command Line] How to activate TUIO

All Displax products offer the end users the possibility to activate the TUIO protocol, allowing them to get over the network values:

  • X coordinate;
  • Y coordinate;
  • Pressure Sensing (only for Displax Skin Ultra);

To activate TUIO follow the next steps:

  • Be sure you are on the location of  Displax Connect installation
  • Start the TUIO server
    • DEVICE_SERIAL_NUMBER : controller serial number
    • tctlrc 1 : this parameter(-tctlrc 1) allows the use of TUIO events with actual geometric calibration values (or - '0' defined not to use the actual geometric calibration values)
    • IP_ADDRESS : the IP of the computer you wish to send the TUIO events (localhost 127.0.0.1)
    • PORT : port you want to use to send the TUIO events (default 3333)
  skin -d DEVICE_SERIAL_NUMBER -tctlrc 1 -tuio IP_ADDRESS:PORT
  • Example
  skin -d 020201000033 -tctlrc 1 -tuio 127.0.0.1:3333

Important: TUIO should only be     configured when all settings are correctly adjusted and    geometric  calibration is performed, do not perform   the calibration with the TUIO  activated.


TUIO     limitations

  1. Windows: Once the Board has been reset or unplugged, then   you should restart TUIO, otherwise TUIO events will stop    being sent  to the host. But if you shutdown or   restart  the computer the  TUIO will  automatically  start and there is no  need to perform  the this   step;
  2. Configuring: TUIO should be configured after configuring   all touch settings (Gain, Threshold, calibration and so  on);
  3. It’s recommended to stop sending TUIO events before  uninstalling ‘Displax Connect’;
  4. If you have a limited Windows account you should start TUIO  as Administrator;
  5. When TUIO is started the Touch Representation in Displax  Connect (touch blobs) can get inverted although this doesn't  affect Geometric Calibration;
