Hi @vorka, interesting setup! Whilst it may be possible to run two eye trackers side by side in the manner you describe, I worry that you won’t be properly positioned that both of them will track properly. Additionally, it may be that light from one of the eye tracker will interfere with the images received on the other tracker, thus affecting the device ability to properly track eye position.
Certainly, I am not aware of another user with this particular configuration, so we cannot guarantee optimal results but assuming that the eye trackers are reasonably parallel, it may work. We would undoubtedly like to hear the results of your experiment!
