If I looked through another person’s eyes, would I see the same as that person?
If I could construct a device to record the view in front of me, a miniature camera I could wear without noticing, and if I could simultaneously track the movement of my eyes, then I would be able to calculate the direction of my gaze and project it onto my recorded scene-view. If I then meticulously constructed a video filter, according to the latest scientific research on how my eyes receive visual stimuli, and applied this to the scene-recording, then I would be able to see what my eyes had seen before my brain had interpreted the input.
This way, I would see the world as it really is, pure and unobscured by neurological filters. And if I asked someone else to wear the device, I would be looking through their eyes. I would be seeing the world as they saw it, for a brief while we’d share the same visual reality, the same vision.
That is, if there would be anything to see at all…
