3D Viewing Position

Of course, these methods produce zones in which the viewer can see a 3D image and the head must be correctly aligned within these zones to comfortably view the scene. If the head is located outside of these zones then both image streams will reach each eye or the viewing positions will be inverted ? both of which will cause comfort problems.

This limits most low/medium end monitors as it restricts the head movement to within a small viewing region to achieve the full 3D effect. High end monitors can use different methods of eye/head tracking to adjust a parallax barrier, altering the viewing zones to follow the eye positions. This provides a seamless 3D viewing experience from an LCD monitor, without any external equipment.
