Virtual light in augmented reality
First Claim
Patent Images
1. A head-mounted display system, comprising:
- an optical sensor system configured to observe ambient lighting conditions of a physical environment;
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.

Abstract
A head-mounted display system includes a see-through display that is configured to visually augment an appearance of a physical environment to a user viewing the physical environment through the see-through display. Graphical content presented via the see-through display is created by modeling the ambient lighting conditions of the physical environment.
