1. A display apparatus comprising: at least one context image projector or at least one context display for rendering a context image, wherein an angular width of a projection of the rendered context image ranges from 40 degrees to 220 degrees; and at least one focus image projector for rendering a focus image, wherein an angular width of a projection of the rendered focus image ranges from 5 degrees to 60 degrees, at least one projection surface; an image steering unit; means for detecting a gaze direction; and a processor coupled in communication with the image steering unit 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: a region of the context image that substantially corresponds to the region of visual accuracy of the input image is masked, the focus image substantially corresponds to the region of visual accuracy of the input image, and the second resolution is higher than the first resolution; (c) render the context image at the at least one context display or at the at least one projection surface via the at least one context image projector; (d) render the focus image at the at least one projection surface via the at least one focus image projector; and (e) control the image steering unit to adjust a location of the projection of the rendered focus image on the at least one projection surface, such that the projection of the rendered focus image substantially overlaps the projection of the masked region of the rendered context image on the at least one projection surface, wherein the processor is configured to perform (c), (d) and (e) substantially simultaneously, and an arrangement is made to combine the projection of the rendered focus image with the projection of the rendered context image to create a visual scene.
