Use Multiple Ubi Cameras

Ubi Support -

If your display is larger than 100 inches, you can use multiple cameras and emitters to cover the entire display.  (You need to use Enterprise edition to use this feature)

Here are the instructions:

  1. Download the latest Ubi . 
  2. Install Ubi on a PC with N (N=number of cameras) separate USB controllers. (Follow this instruction to verify). If your PC doesn’t have N USB controllers, your system might run into detection and performance issues later.
  3. Label camera and USB port (with color or labels). Always connect the matching camera and port in the future.
  4. Make sure all the cameras are disconnected from PC.
  5. Start Ubi from Windows Start menu. UbiService window will show up.
  6. Go to Setting -> Advanced->Show Advanced Setting and choose  
    • Calibration -> Calibration Area ->Resizable
    • Calibration -> Duplicate or Extend -> Extended
    • Hardware -> Multiple camera.
    • Click “Save”.
  7. Connect first camera to the matching port. Ubi Main App will start.
  8. Resize and Drag Ubi Main App to cover the area you want to interact.
  9. Choose "Standard Setup" and follow the in-app instruction to mount the camera and emitter.
  10. Test interaction after calibration. If the interaction is accurate and stable, Quit Ubi from UbiMenu, disconnect the first camera and connect the second camera and repeat the steps 9 - 11.
  11. Repeat and calibrate all the cameras one by one.
  12. Once all the cameras are calibrated, disconnect all cameras, go to UbiService and click “Settings” -> “Skip Calibrate” -> Save, so you don't need to calibrate next time.
  13. Go to Setting -> Advanced->Show Advanced Setting and choose UbiMenu -> Menu-> Hide
  14. Connect cameras back to the matching port. All cameras should start and skip calibrate.
  15. Touch the display to verify the points are detected across the whole display wall.
  16. Since the UbiMenu does not show up anymore. You need to quit Ubi from the UbiService.
  17. If one area doesn’t work so well, you can keep this camera connected, disconnect the other cameras and restart UbiService.exe to just calibrate for that camera.

You can restart the machine to test if all calibration data are saved.

 

Troubleshooting:

If you want to recalibrate one camera, you need to unplug all the cameras and just connect the target camera, and go to UbiService->Setting->Standard calibrate and do the calibration. Once it is calibrated, change to UbiService->Setting->Skip Calibrate.

If one camera is not detected by Ubi, disconnect and connect it back.

If Ubi main app does not start when camera is connected, check in TaskManger and make sure there is no Ubi4Ubi.exe is running. If there is one, select the process and end process. After that, reconnect the camera.
