Abstract: An update basis for updating digital content in a digital medium environment is described. The digital content is updated by incorporating new digital content components from a service provider system, such as a stock content service, to keep the digital content from seeming stale to client device users. The service provider system controls provision of digital content components according to an update basis described in a component request. In part, component requests ask that the service provider system provide digital content components for incorporation with digital content. Component requests also describe a timing basis with which digital content components are to be provided as updates. By way of example, the timing basis may correspond to a time interval (e.g., daily, weekly, monthly, seasonally, times of day, and so on), receiving user input in relation to the digital content (e.g., a navigation input to a web page), and so forth.

Abstract: Attribute control for updating digital content in a digital medium environment is described. The digital content is updated by incorporating new digital content components from a service provider system, such as a stock content service, to keep the digital content from seeming stale to client device users. The service provider system controls provision of digital content components based on fixed and variable attributes specified for these digital content components. Initially, the service provider system receives a component request, requesting that the service provider system provide the digital content components for incorporation with the digital content. The component request specifies fixed and variable content attributes for the provided digital content components. A fixed content attribute is an attribute that is to be included in the provided digital content components.

Abstract: Content creation and sharing integration techniques and systems are described. In one or more implementations, techniques are described in which modifiable versions of content (e.g., images) are created and shared via a content sharing service such that image creation functionality used to create the images is preserved to permit continued creation using this functionality. In one or more additional implementations, image creation functionality employed by a creative professional to create content is leveraged to locate similar images from a content sharing service.

Abstract: A digital medium environment includes at least one computing device (e.g., a user's mobile device) in an environment. Systems and techniques are described for presenting a photorealistic augmented reality experience in real time on the computing device. A lighting representation of the environment is obtained from a partial view of the environment, such as from an image of the environment, and used to render a 3D asset (e.g., graphics of a synthetic object). The 3D asset is inserted into the environment by compositing the rendered 3D asset with the image of the environment accounting for occlusion and based on the lighting representation to form a composite image. Photorealistic processing is applied to the composite image by adding lighting for the rendered 3D asset to a portion of the background of the composite image. Consequently, the inserted graphic is indistinguishable from the real-world scene.

Abstract: Content creation collection and navigation techniques and systems are described. In one example, a representative image is used by a content sharing service to interact with a collection of images provided as part of a search result. In another example, a user interface image navigation control is configured to support user navigation through images based on one or more metrics. In a further example, a user interface image navigation control is configured to support user navigation through images based on one or more metrics identified for an object selected from the image. In yet another example, collections of images are leveraged as part of content creation. In another example, data obtained from a content sharing service is leveraged to indicate suitability of images of a user for licensing as part of the service.

Abstract: Image compensation for an occluding direct-view augmented reality system is described. In one or more embodiments, an augmented reality apparatus includes an emissive display layer for presenting emissive graphics to an eye of a user and an attenuation display layer for presenting attenuation graphics between the emissive display layer and a real-world scene to block light of the real-world scene from the emissive graphics. A light region compensation module dilates an attenuation graphic based on an attribute of an eye of a viewer, such as size of a pupil, to produce an expanded attenuation graphic that blocks additional light to compensate for an unintended light region. A dark region compensation module camouflages an unintended dark region with a replica graphic in the emissive display layer that reproduces an appearance of the real-world scene in the unintended dark region. A camera provides the light data used to generate the replica graphic.

Abstract: Digital content interaction and navigation techniques and systems in virtual and augmented reality are described. In one example, techniques are employed to aid user interaction within a physical environment in which the user is disposed while viewing a virtual or augmented reality environment. In another example, techniques are described to support a world relative field of view and a fixed relative field of view. The world relative field of view is configured to follow motion of the user (e.g., movement of the user's head or mobile phone) within the environment to support navigation to different locations within the environment. The fixed relative field of view is configured to remain fixed during this navigation such that digital content disposed in this field of view remains at that relative location to a user's field of view.

Abstract: Font replacement based on visual similarity is described. In one or more embodiments, a font descriptor includes multiple font features derived from a visual appearance of a font by a font visual similarity model. The font visual similarity model can be trained using a machine learning system that recognizes similarity between visual appearances of two different fonts. A source computing device embeds a font descriptor in a document, which is transmitted to a destination computing device. The destination compares the embedded font descriptor to font descriptors corresponding to local fonts. Based on distances between the embedded and the local font descriptors, at least one matching font descriptor is determined. The local font corresponding to the matching font descriptor is deemed similar to the original font. The destination computing device controls presentations of the document using the similar local font. Computation of font descriptors can be outsourced to a remote location.

Abstract: In embodiments of event image curation, a computing device includes memory that stores a collection of digital images associated with a type of event, such as a digital photo album of digital photos associated with the event, or a video of image frames and the video is associated with the event. A curation application implements a convolutional neural network, which receives the digital images and a designation of the type of event. The convolutional neural network can then determine an importance rating of each digital image within the collection of the digital images based on the type of the event. The importance rating of a digital image is representative of an importance of the digital image to a person in context of the type of the event. The convolutional neural network generates an output of representative digital images from the collection based on the importance rating of each digital image.

Abstract: Digital content rendering coordination techniques in augmented reality are described. In one example, a user is provided with a first display device via which an augmented reality environment is to be viewed that includes at least a partial view of a physical environment. As part of this physical environment, a second display device (e.g., a desktop monitor, a mobile phone, and so forth) is also viewable by a user through the first display device, i.e., is directly viewable. Techniques are described herein in which a view of digital content on the second display device is coordinated with a display of digital content on the first display device. This may be used to support a variety of usage scenarios to expand and share functionality associated with these different devices.

Abstract: Techniques and systems are described to implement a platform to create and disseminate virtual user experiences. In one example, a service provider exposes a platform usable for creation of virtual user experiences. In another example, a service provider exposes functionality to enable specification of physical environment conditions to be met in order to cause dissemination of respective virtual user experiences maintained by the service provider. In one instance, triggers are detected by a computing device of a user that are indicative of a likelihood to cause output of a virtual user experience. Once triggered, the computing device communicates data describing physical environment conditions to the service provider. The service provider then matches these conditions to specified physical environment conditions that are to be used to control dissemination of the virtual user experience.

Abstract: Digital content view control techniques are described. In one example, a virtual control is used to supplement navigation of digital content without movement of a user's head through use of an appendage such as a hand, finger, and so forth. In another example, a digital content view control technique is configured to reduce potential nausea when viewing the digital content. Techniques and systems are described that incorporate a threshold to control how the digital content is viewed in relation to an amount of movement to be experienced by the user in viewing the digital content. Based on this amount of movement, a determination is made through comparison to a threshold to control output of transitional viewpoints between the first and second viewpoints.
