The setup program could begin by having you first putting the Rift on and taking a photo of the eyes/eyebrows and mouth with the face at rest, then having you take the rift off. Step 2 would be taking video of the the forehead, with the aid of an on-screen positional aid. It would instruct the user to start with their eye brows at rest, then move them up as much as they could, then in towards each other as much as they could -to capture various conditions of the forehead as the skin ripples together. Step 3 would be asking the user to center the recorded forehead image over a trapezoidally shaped area (or opposite, the trapezoid over the video). Step 4 would be a similar process with the nose.
Using this information, the software would dynamically update the photo of the forehead and nose area, the areas the cameras don't capture, based on the condition of the eye brows, most importantly their vertical position, as compared to the reference frames capture by the setup software in step 2. Same for the nose area hidden by the Rift, which would be affected by the movement of the mouth and jaw.
I say two cameras below the Rift (4 in total) because you'd probably miss the sides of the mouth and face with only one.
To get the body of the eye/eyebrow cameras out of the way, you could use mirrors.
Instead of inserting cameras within the Rift itself, you could design future Rifts to except a lightweight metal or plastic template that snapped in inside viewport body of the rift perhaps underneath'ish the cushion -that held the cameras, thus making it an optional accessory.
Just imagine the heighten ability to emotionally interact with your friends. Like your sneaking into a dungeon and a huge thing crosses your path in the distance and you look back at your friend [in India] and smile and give a HO... LY... crap look and a smile.
If you make a quadrillion bucks off of this idea, I beseech thee to send me a million, deal? I've got a bunch of OR inventions i'd like to get made, but I unfortunately don't have the faintest interest in almost anything that makes one money....
