1. A system comprising:
tracking means;
a display device comprising:
a backlight;
a first polarizer and a second polarizer having a first polarization orientation and a second polarization orientation, respectively, wherein the first polarizer is arranged between the backlight and the second polarizer; and
a first liquid crystal layer and a second LC layer arranged between the first polarizer and the second polarizer, the first LC layer being adjacent to the first polarizer, the second LC layer being adjacent to the second polarizer, wherein the first LC layer and the second LC layer have a gap therebetween, each of the first LC layer and the second LC layer comprising a plurality of LC cells; and
at least one processor configured to:
utilise the tracking means to determine a relative location of a first eye and of a second eye of at least one user with respect to an image plane of the display device;
obtain a first virtual image and a second virtual image to be presented to the first eye and the second eye of the at least one user, respectively, based on the relative location of the first eye and of the second eye of the at least one user with respect to the image plane; and
generate drive signals for the LC cells of the first LC layer and the LC cells of the second LC layer, based on the first virtual image, the second virtual image, and the relative location of the first eye and of the second eye of the at least one user with respect to the image plane,
wherein the LC cells of the first LC layer and the LC cells of the second LC layer are controlled using the drive signals, to adjust a polarization of light passing therethrough, for producing a synthetic light field presenting the first virtual image and the second virtual image to the first eye and the second eye of the at least one user, respectively.
