Abstract: A method, apparatus, and article of manufacture provide the ability to interface with objects. A computer-implemented scene having two or more objects is displayed and a corresponding list of the two or more objects is displayed in independent categories called facets and in an ungrouped flat list. A user identifies a viewpoint within the scene that establishes a location and an orientation within a space of the scene from which to view the scene objects. Dynamically and independently from additional user actions, a proximity of each of the two or more objects from the viewpoint is determined. The ungrouped list of the two or more objects is sorted based on the proximities and displayed.

Abstract: This invention relates to optoelectronic devices of improved efficiency. In particular it relates to light emitting diodes, photodiodes and photovoltaics. By careful design of periodic microstructures, e.g. gratings, associated with such devices more efficient light generation or detection is achieved.
