If your display is larger than 85" inches, you can use multiple cameras and emitters to cover the entire display. See the picture below for such a sample set up. (You need to use Enterprise edition to use this feature).
How does it work?
The multiple sensor set up is one of the most common use cases of Ubi. One pair of sensor camera and emitter supports only display sizes upto 85". If your display is larger than that, you will need to use multiple sensors and emitters. You will essentially divide up the display into multiple smaller areas and use a pair of sensor camera and emitter in each of these areas.When Ubi is launched it will help you calibrate each of these areas separately. Once the interaction starts, Ubi software will detect input from each sensor camera, merge them and send as input to any app running on your PC.
Please note that Ubi sensor cameras and emitters are not tied to how many projectors you use. At the end of the day, Ubi sees the entire display as a single display.
For the most optimal placement of cameras and emitters, please contact us with the exact size of your display. We can help you ensure, the best interaction experience using the least amount of hardware.
We recommend two options to arrange the hardware set up.
If your display is less than 45" or 1.2m in height, we recommend the landscape mode. In this set up, your display will be split into sections that are at most 45" ( 1.2m ) in height and 75" in width (1.9m) . If your display is lets say 3m wide and 1.2m tall, you will split into areas of 1.5m x 1.2m. You will then need two sensors and two emitters.
If your display is taller than 1.2m in height, we recommend the portrait mode. In this set up, your display will be split into sections that are at most 2.1m in height and 1.5 m in width . If your display is lets say 3m wide and 2.1m tall, you will split into areas of 1.5m x 2.1m. You will then need two sensors and two emitters.
Here are the instructions for configuring and running Ubi software with multiple sensors.:
- Find a PC that has multiple USB controllers. (Caution: USB controller is not USB port.) The number of USB controllers should match the number of cameras you need to use. Download this application USB View and Follow this instruction to verify)
- Download the latest Ubi and install on the PC.
- Label camera and USB controllers (with color or labels). Always connect the matching camera and controllers in the future.
- Make sure all the cameras are disconnected from PC.
- Start Ubi from Windows Start menu. UbiService window will show up.
- Go to Setting -> Advanced->Show Advanced Setting and choose
- Calibration -> Calibration Area ->Resizable
- Calibration -> Duplicate or Extend -> Extended
- Hardware -> Multiple camera.
- Click Save.
You can restart the machine to test if all calibration data are saved.
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 TaskManager 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.
