Abstract: Various embodiments are generally directed to techniques for crowdsourcing metadata, such as to create, maintain, utilize, and/or communicate metadata in a datastore. Some embodiments are particularly directed to collecting, managing, and/or distributing metadata via a user interface application (UIA), or an extension thereof. Many embodiments may facilitate collaborative creation of a repository for metadata, such as notes, characteristics, and/or statistics corresponding to data viewed with the user interface application. For example, the comments regarding websites may be collected from a first user via a first instantiation of the web browser extension and distributed to a second user via a second instantiation of the web browser extension. In several embodiments, the metadata may be collected and managed with instantiations of the web browser extension (herein after “WBE instants”) and a data manager may create, maintain, utilize, and/or communicate metadata in a datastore.

Abstract: A method and apparatus for mass production of AR diffractive waveguides. Low-cost mass production of large-area AR diffractive waveguides (slanted surface-relief gratings) of any shape. Uses two-photon polymerization micro-nano 3D printing to realize manufacturing of slanted grating large-area masters of any shape (thereby solving the problem about manufacturing of slanted grating masters of any shape on the one hand, realizing direct manufacturing of large-size wafer-level masters on the other hand, and also having the advantages of low manufacturing cost and high production efficiency). Composite nanoimprint lithography technology is employed (in combination with the peculiar imprint technique and the composite soft mold suitable for slanted gratings) to solve the problem that a large-slanting-angle large-slot-depth slanted grating cannot be demolded and thus cannot be manufactured, and realize the manufacturing of the slanted grating without constraints (geometric shape and size).
