Claim One:
1. A display apparatus comprising: at least one context image renderer for rendering a context image, wherein an angular width of a projection of the rendered context image ranges from 40 degrees to 220 degrees; at least one focus image renderer for rendering a focus image, wherein an angular width of a projection of the rendered focus image ranges from 5 degrees to 60 degrees; and at least one optical combiner for combining the projection of the rendered context image with the projection of the rendered focus image to create a visual scene, means for detecting a gaze direction; and a processor coupled in communication with the at least one optical combiner and the means for detecting the gaze direction, wherein the processor is configured to: (a) receive an input image, and use the detected gaze direction to determine a region of visual accuracy of the input image; (b) process the input image to generate the context image and the focus image, the context image having a first resolution and the focus image having a second resolution, wherein: (i) the focus image substantially corresponds to the region of visual accuracy of the input image, and (ii) the second resolution is higher than the first resolution; and (c) render the context image at the at least one context image renderer and the focus image at the at least one focus image renderer substantially simultaneously, whilst controlling the at least one optical combiner to combine the projection of the rendered context image with the projection of the rendered focus image in a manner that the projection of the rendered focus image substantially overlaps a projection of a region of the rendered context image that substantially corresponds to the region of visual accuracy of the input image wherein the visual scene is created in a manner that at least two different optical distances are provided therein.
