[Solved] work with projector

[Ling-Li Tseng]

Hello,
I am trying to use projector work with Tobii EyeX. Am I doing something impossible ? Or there is some tips I can set up properly ? So far, I couldn’t get any success calibration. Thanks!!!

Hello Ling-Li,

It should be no problem using the eye tracker with a projector as long as you replicate the screen where you mounted the eye tracker to the projector. You will have to calibrate the eye tracker for the resolution used by the projector.

Best regards
Patrik

Hi, I am also hoping to use the EyeX with a projector, I have a 100″ screen that is 3 meters away and a coffee table in front of the sofa. Will it be possible to use EyeX? I mentioned the table as I assume that I will need to place the tracker on that instead of under the screen?

What would be the procedure of setting the system up? I don’t quite understand your comment above.

What does “replicate the screen where you mounted the eye tracker to the projector.” mean? Sorry if I am being stupid!!

Many thanks, James

Hi James,

Hm, I think Patrik misunderstood the original question. What we support is the use of a projector as a secondary monitor, duplicating what is displayed on a monitor where an EyeX Controller is attached.

For example, if you have a laptop with an EyeX Controller mounted on the laptop display, and want to demo your new and exiting game with eye-gaze features on a big screen using a projector, you do like this:
1) before attaching the projector to the laptop:
1.1) set the laptop screen resolution to the same resolution as the projector
1.2) do a calibration
2) attach a projector to the laptop, and duplicate the laptop screen to the projector
3) demo your game

It is not currently possible to use the EyeX Settings or API to set up the eye tracker to be mounted anywhere else than directly on a laptop or desktop display. The setup you are describing would require another kind of advanced screen setup that we currently do not support in EyeX.
