My idea is of a gaze-based keyboard passthrough that shows my real keyboard when I look down, then hides it when I look up.
It would work something like this: When I glance down right at my keyboard a passthrough window pops up showing my real keyboard and hands (maybe with opacity setting?). And when I look away it fades out, keeping me in VR. Since the Q3 and newer all have forward facing cameras I'm thinking it could work somehow maybe. It would make typing in VR games or apps easier without affecting immersion much. Could this be a Horizon OS feature?
