I am trying to make some objects in my mod that would act as NPC's.

One is more complicated than the other but the basic idea is the same.

One is called a Deathman Labs Virtual Holographic Interface. It will project a 3D hologram of an avatar to relay information over a pad, when a touchscreen is right clicked.

The other is the mainframe. She is an artificial intelligence, that starts off very basic. She will ask you to do quests for her. For instance "Did you know, if you program a expansion chip with a voice generation program, I will be able to speak, and you won't have to read this text.' Or, 'I seem to have forgotten that I do not have speakers. Please give me some, two are required.' So yeah, she wants new things. She would have three basic screens. All the screens would have the same setup. A blue box to the right, and a view of her model to the left. Like  Darksiders 2 shops.

So that, reversed, and blue.

I do not want to render another model in the GUI, I wish to have the gui have a hole there, where the player's view would be placed so she would be in the hole.

I looked at the bed code, but that of course moves the entire person, I don't want to reposition the person, as the model is only 1.5 blocks tall.

I can code everything else, it's just the view.

Is there a way to control the camera, I think I saw that somewhere.

This should help:

entityplayer.setPositionAndRotation(posX, posY, posZ, yaw, pitch);

 

Note that you can use entityplayer.posXYZ to stay at the same pos.
