    a position sensor system configured to assess a perspective of the optical sensor system; and

    a see-through display configured to visually augment an appearance of the physical environment with a virtual object, the see-through display creating an illusion of a virtual shadow of the virtual object by virtually illuminating a non-shadow region bordering the virtual shadow, an appearance of the non-shadow region being based on the observed ambient lighting conditions.
