Mounting emitter with screws will guarantee a great performance over long time. We highly recommend using screws whenever possible.
The emitter drops an infrared curtain in front of the display which, when intercepted with your finger, signals a touch event. The interaction surface must be absolutely flat and stable (hanging canvas won't work).
For Ubi Emitter v2
- Screw the emitter base plate 2 inches above the display
- Snap the emitter unit on the base plate.
- Tilt the emitter unit using the three knobs.
- Verify the setup and interact.
For Ubi Emitter v1
Below are the steps to mount emitter with screws.
- Drill four small mounting holes.
- Paste emitter with mounting holes aligned.
- Tilt the emitter by hand to make it parallel to surface.
- Screw the emitter once the position is found.
- Verify the setup and interact.
