Abstract
Various implementations provided herein provide content on an optical see-through display using enhanced local contrast. In some implementations, the enhanced local contrast may be used to provide an apparent reduction in brightness (e.g., a shadow) or other visual effect. For example, the appearance of a virtual shadow of a virtual cup on a real table of a physical environment can be provided even though the brightness of the table cannot be reduced. The appearance of the shadow may be provided by selectively enhancing contrast that the user cognitively interprets to see a relatively “darker” area where the shadow should be (e.g., via an optical illusion/effect).
