What we have today is called "teleprompter", and not even particularly recent. With some slight pre-distortion and a tilted monitor it should also handle the focus issue a classic teleprompter setup has. Basically, you just place a half-reflective mirror at a 45 degree angle, lay the screen flat facing up (I propose a slight back-tilt "so the camera can see better", but you loose contrast due to viewing angle, which would ideally be corrected by the LCD), and look at the camera that's behind the mirror, while being able to view the screen in the mirror.
