Patent Images

1. A method of operating a see-through display including a plurality of at least partially transparent pixels, the method comprising:

  • displaying an image of a virtual object with an object subset of the plurality of at least partially transparent pixels by directing additive image light to a user eye via the object subset of the plurality of at least partially transparent pixels such that the virtual object appears in front of a real-world background when viewed through the see-through display; and

    creating an illusion of a virtual shadow with a shadow subset and a neighboring background subset of the plurality of at least partially transparent pixels by not directing additive image light to the user eye via the shadow subset while directing additive image light to the user eye via the neighboring background subset in a vignette pattern displayed with greater brightness adjacent the virtual shadow and displayed with decreasing brightness away from the virtual shadow such that the virtual shadow appears to result from a spotlight that is fixed relative to a vantage point of the see-through display.
