Gaze Interaction offset to aim at peripheral areas

I would like to create a Gaze based Interaction but instead of the center view being the aim to trigger events I would instead like the areas in the peripheral vision to trigger them.

I understand that normal Gaze is a single point, and that the peripheral vision is an area, but is there a way to move the gaze point to the sides of the screen and possibly have multiple ones? So I’m imagining maybe one point in each corner. If that’s possible could you then change the aim points to be areas as well?

Could this be possible in Blueprints or am I asking for too much? Any help would be greatly appreciated.
