I changed my idea, and I will build a small AR display kind of like this one. I couldn’t find a display that would work with the beam splitter cube, but after a while, I found one. I’m also thinking of using a different microcontroller than my originally intended Pi 4B that I have lying around, because I will need it for a different project, and I want to see if I can use a smaller ESP-32 to make it more compact, so you can put it in your pocket, and sneak it around. I’m thinking of having the camera kind of like a lavalier mic, that you can clip onto your shirt.
