Imagine a hollow cube. The top and bottom are opaque, put a video camera on the left and a video screen on the right(or vice versa), put a mirror across the middle at 45° so the camera looks out the front and the screen displays out the back. Mount two of these in glasses such that each eye looks in the back of one cube, and have software modify the camera image in accordance with AR before passing it to the display. That's what I was starting with. That alone would make the wearer effectively count as a machine for Invisibility purposes, barring Glamour etc.

Replace the mirror with two beam-splitters, one "in reverse", which will probably require lengthening the optical column. A partial image is then passed through without machine alteration, and you can partly see through anything with Invisibility. (I figured it'd be easy for modern westerners to train "translucent people are invisible", since that's how our media often shows invis.)
