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;
