The present disclosure relates to an augmented reality system for real space navigation. The augmented reality system comprises a navigation module for determining a set of spatial coordinates corresponding a position in a three dimensional real space for each of a plurality of navigation landmarks; and a virtual image display module for displaying a virtual image correlated to one of the plurality of navigation landmarks such that the virtual image is perceived by a user to be at the position in the three dimensional real space, the virtual image being composed of at least one binocular pixels, each of the binocular pixels is formed by a first light signal projecting to a first retina of the user and a second light signal projecting to a second retina of the user.
