Abstract
A display apparatus including at least one image renderer; light sources; controllable scanning mirrors; at least two actuators associated with the controllable scanning mirrors; means for detecting gaze direction of user; and a processor communicably coupled to the aforementioned components. The processor is configured to: (a) obtain an input image and determine region of visual accuracy thereof; (b) process the input image to generate a context image and a focus image; (c) determine a focus area within a projection surface over which the focus image is to be drawn; (d) render the context image; (e) draw the focus image; and (f) control the actuators to align the controllable scanning mirrors. The processor is configured to perform (d), (e) and (f) substantially simultaneously, and optically combine a projection of the drawn focus image with a projection of the rendered context image to create a visual scene.
