Overview of the Whiteboard Setup.


The diagram shows an overview of the hardware setup. Use this setup if you are projecting your display on a whiteboard. The Ubi camera and emitter work together to turn your whiteboard into a touch screen.
The Ubi camera is plugged into a PC and the emitter is plugged into a power supply.
Setup steps:

  • Create an 40 – 80” display on whiteboard
  • Mount the Ubi camera
  • Mount the emitter
  • Fine-tune the setup






Select your setup


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




Create an 80” display.


Adjust your projected display so that it fits within your whiteboard. Be sure to leave some space between the top of the whiteboard and the display. There should also be some space between the bottom of the display and the whiteboard.
Be sure that there is no direct sunlight hitting the whiteboard and that there are no other objects on or around the display.
If your projector is in a fixed position and you cannot move it or shrink your display, please follow these instructions.



Mount the camera.


The camera needs to be mounted approximately 30 inches from the display.

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 can be affixed using the tape or screws provided. We recommend using the screws for permanent setups.


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 1-2 inches from the top of the display. The emitter should be placed directly on the whiteboard and not on the beveled edge.


TThe 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.


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. After calibration, the emitter is turned on by the Ubi camera and will display a faint blue light. If the emitter does not turn on, please follow these instructions.
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 only two crosshairs appear, one 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.
