Gaze trace is just for visualization and it’s not directly connected to how interactors work.
We also don’t recommend continuously showing gaze overlay to users, it’s more a debug tool.
You can also download a standalone streaming overlay with configuration tool.
Interactors can be designed in such a way so it’s only one of them selected at a time (see sdk examples). But we strongly recommend having reasonable size of UI elements in this case.
Could you please provide us more details on your project so we can help you in the best way?
