Overview of the Standard Setup.


The diagram shows an overview of the standard setup. This set up is to be used for projection displays on a wall that is upto 80″ in size.

The Ubi camera and emitter work together to turn your surface into a touch interface.

The Ubi camera is plugged into a PC and the emitter is plugged into a power supply.
Setup steps:

  • Create an 80” display
  • Mount the Ubi sensor
  • Mount the emitter on the wall






Select your setup


When running Ubi in the “Step by Step Calibration” mode, choose “Standard Setup” and proceed.




Create an 80” display.


Ubi’s standard setup supports an 80 inch (diagonal) display. The display should be a projection display onto a solid flat wall. There should be no other objects on the display.
Note: Ubi cannot be used with pull down projection screens.
If your projector is in a fixed position and you cannot move it or shrink your display, please follow these instructions.



Mount the camera.


There are 3 options for mounting the camera:

1. Use the ceiling mount if your ceiling is not too high and you do not have a short throw projector.

2. The wall mount can be mounted above the display or on the ceiling. Use the wall mount if you do not have a short-throw projector or if you have a high ceiling.

3. Place the camera on the projector if you have a short throw projector.

All mounts, except the projector mount, needs to be affixed using screws provided. For the projector mount, you can use the thick tape provided.


No Camera on Table



Mounting the camera using the ceiling mount


The ceiling mount is affixed to the ceiling 7 inches from the top of the projected display and 30 inches from the wall. The ceiling mount should be placed at the center of the display. You can use the tape or screws provided. We recommend using the screws for permanent setups.


Using the wall mount.


The wall mount is affixed 7 inches from the top of the projected display using the screws provided. The camera should be approximately 30 inches from the wall. The wall mount should be positioned at the center of the display.

Please watch the video on how to assemble the wall mount.


Mounting on the projector.


If you are using a short throw projector, you can mount the camera on the projector as long as it is 30 inches from the display. Use the base used for the ceiling mount and affix it to the projector using the tape provided.




Connect the camera.


Connect the camera to the PC. Use the USB cable provided.
If Ubi is having trouble connecting to the camera, please follow these troubleshooting steps.



Camera preview.


The camera preview shows you how much of your display the camera can see. Adjust your display until all of your display can be seen by the camera. If you cannot shrink the display, move the position of the camera. For optimal performance, make sure the display fills up as much of the camera preview as possible.

Once you click the Calibrate button, a dot pattern will quickly flash and if the calibration is successful, you will proceed to mount the emitter.

If calibration fails, it is likely due to the following reasons:

1. There is not enough contrast and the camera cannot see all of the display. In this case, adjust the room lighting or brightness of the projector.

2. The entire display is not within view of the camera.

3. There is too much clutter on or around the display that causes Ubi to detect more than 36 calibration dots.



Mount the emitter.


The emitter is placed 2-3 inches from the top of the display.


The emitter drops an infrared curtain in front of the display which, when intercepted with your finger, signals a touch event.
The infrared curtain must be parallel to the surface so please make sure your surface is flat and smooth. If you are using a whiteboard, the emitter should be placed directly on the whiteboard and not on the beveled edge.


Affix the markers on the display.


Place the two markers provided directly on your display at the location specified (dotted circles).



Power up the emitter.


Connect the emitter to the power supply. The emitter is turned on by the Ubi sensor and will display a faint blue light. When the emitter is off, it will display a red light.
Please note that the emitter should be powered down when Ubi is not in use.


Adjust the emitter.


Use the markers and cross hairs to determine when the IR curtain is parallel to the surface. Once the emitter is affixed to the wall, adjust the emitter so that some partof the circular cross hair appears on each marker. Once the emitter is in its final position, you should see a cross hair exactly at your fingertip as you touch around the screen.


Remove the markers.


One the emitter is in its final position, you can remove the markers from your display surface.




Successful Setup.


Once the emitter is in its final position, you have completed the setup process. You will be prompted to choose how you would like to calibrate the next time you use Ubi.
We recommend selecting auto-calibrate if you do not intend to change your setup.
