I think that there is an ongoing conspiracy in the philosophical community, an organized form of self-deception, as in a cult, to simply all together pretend that we knew what "first-person perspective" (or "quale" or "consciousness") means, so that we can keep our traditional debates running on forever.

In ordinary life, the phenomenology of embodied emotions is an excellent example for dynamic changes between transparency and opacity: You can "directly perceive" that your wife is cheating you, or you can become aware of the possibility that maybe it is you who has a problem, that your "immediate" emotional representation of social reality might actually be a misrepresentation.

I believe that if we would carefully apply the distinction between transparency and opacity to the different layers of the human self-model, looking at self-consciousness in a much more careful and fine-grained manner, then we might also arrive at a new answer to your original question: What a "first-person perspective" really is.

As modern-day neuroscience tells us, we are never in touch with the present, because neural information-processing itself takes time. Signals take time to travel from your sensory organs along the multiple neuronal pathways in your body to your brain, and they take time to be processed and transformed into objects, scenes, and complex situations. So, strictly speaking, what you are experiencing as the present moment is actually the past.

I believe that gut feelings, the sense of balance, and spatial self-perception are so firmly coupled to our biological body that we will never be able to leave it experientially on a permanent basis.

Consciousness is phenomenologically subjective whenever there is a stable, consciously experienced first-person perspective.

Virtual reality is the representation of possible worlds and possible selves, with the aim of making them appear as real as possible - ideally, by creating a subjective sense of "presence" and full immersion in the user.
