Abstract: A method includes generating a local map of a real environment, the local map being defined by first spatial relationships between first feature descriptors corresponding to a visible feature in the real environment captured by a device. The device receives a downloaded map defined by second spatial relationships between an anchor point and second feature descriptors corresponding to visible features captured by another device, wherein the anchor point corresponds to a location of a virtual object. The local map is updated by merging the downloaded map with the local map based on a comparison between the first feature descriptors and the second feature descriptors and a pose of the device is determined relative to a particular feature descriptor in the updated local map. Virtual content is rendered based on the pose and one or more spatial relationships linking the particular feature descriptor and the anchor in the updated local map.

Abstract: Automatic manipulation of document user interface behavior is provided based on an insertion point. Upon placement of an insertion point within a displayed document, the behavior of the user interface is adjusted based on a next action of the user. If the user begins a drag action near the insertion point, he/she is enabled to interact with the content of the document (e.g. select a portion of text or object(s)). If the user begins a drag action at a location away from the insertion point, on the other hand, he/she is enabled to interact with the page (e.g. panning) Thus, the interaction behavior is automatically adjusted without additional action by the user or limitations on user action.

Abstract: Techniques for generating custom objects for content files are described. An apparatus may comprise a logic device arranged to execute a montage application comprising an authoring component operative to generate a tile object for a digital montage, the authoring component to receive a control directive to associate a content file with a presentation tile of a presentation surface of the digital montage, identify a content file type for the content file, and generate the tile object with information from the content file in accordance with the content file type. Other embodiments are described and claimed.
