Abstract

A display apparatus, and a method of displaying via the display apparatus. The display apparatus includes at least one context image renderer for rendering a context image, at least one focus image renderer for rendering a focus image, at least one first optical combiner for combining the projection of the rendered context image with the projection of the rendered focus image to form a combined projection, and at least one second optical combiner for combining the combined projection with a projection of a real world image. An angular width of a projection of the rendered context image ranges from 40 degrees to 220 degrees. An angular width of a projection of the rendered focus image ranges from 5 degrees to 60 degrees.
