Abstract: In some examples, a computing device may receive an indication that a first user and a second user are located in a zone of an interior space or other surrounding environment. Settings of one or more controllable devices may be controlled based on user profiles including implicit or explicit user preferences, such as for controlling lighting, ambient temperature, entertainment, security, etc., in the zone. When there is conflict between the user preferences, the conflict may be resolved, such as by determining a hierarchy between the users, by averaging the preferred settings, or based on other techniques. Further, a portable computing device may be associated with a user and may provide sensor information. The sensor information may include biometric sensor information that is indicative of a bodily condition of the user and that can be used for determining a context of the user or the zone.

Abstract: Techniques for providing notifications to user devices for the purpose of re-engaging users in content items they are consuming, such as electronic books, movies, videos, and the like. For instance, the techniques may calculate a frequency at which a user reads an electronic book. If the user does not request to read this electronic book for an abnormal amount of time, the techniques may provide a notification encouraging the user to again read the electronic book.

Abstract: In some implementations, a device displays a user interface that provides supplemental information in connection with a digital work. For example, the supplemental information may include a listing of objects identified in the digital work. Further, a visual representation may be displayed with each listed object. The visual representation for each listed object may provide a representation of at least one location of at least one occurrence of the object in the digital work. The objects may be displayed according to a supplemental information view, a page view, a chapter view, a book view, a series view, a library view, or the like. Additionally, one or more object buttons may be displayed concurrently with the listing of objects. The object buttons may correspond to the types of objects displayed, and may be selected to limit the displayed objects to a particular type.

Abstract: Techniques for facilitating collaborative consumption of content items, such as electronic books, movies, videos, songs, and the like. Multiple users may consume a content item over a substantially common period of time, such as over a day, week, month, etc. Each user may utilize one or more electronic devices (e.g., electronic book reader devices, tablet devices, laptop computers, etc.) to consume the item, and each user may share his or her thoughts and may otherwise provide progress updates to the other users over the period of time.

Abstract: In some implementations, a first user associated with a first user account may send a request to exchange digital libraries with a second user associated with a second user account. Upon acceptance, the second user receives first library information associated with the first user account that identifies content items that may be accessed by the second user due to the exchange. Similarly, the first user receives second library information associated with the second user account that identifies second content items that may be accessed by the first user. In other examples, a user may access the digital library of a selected person or entity, such as a historical figure, celebrity, author, friend, or organization. Additionally, in some cases, a user may view content of a content item that a selected person is currently reading, and which may include annotations made to the content item by the selected person.

Abstract: Highlights from a community of users highlighting portions of an electronic digital content are analyzed and popular highlights determined. The popular highlights are then distributed to the users.

Abstract: A popular highlight may be presented to a user who wishes to make the popular highlight a personal user highlight. Upon activation of a control, a personal user highlight is generated from the popular highlight. The user may then manipulate the resulting personal user highlight as they would any other user highlight.

Abstract: In some implementations, a first user associated with a first user account may send a request to exchange digital libraries with a second user associated with a second user account. Upon acceptance, the second user receives first library information associated with the first user account that identifies content items that may be accessed by the second user due to the exchange. Similarly, the first user receives second library information associated with the second user account that identifies second content items that may be accessed by the first user. In other examples, a user may access the digital library of a selected person or entity, such as a historical figure, celebrity, author, friend, or organization. Additionally, in some cases, a user may view content of a content item that a selected person is currently reading, and which may include annotations made to the content item by the selected person.

Abstract: Some examples include determining a proximity between a first user device and a plurality of other user devices based at least in part on comparing location information of the first user device with location information for the plurality of other user devices. Additionally, a commonality may be determined that is associated with at least some user profiles of the other users, but is unassociated with a user profile of the first user. For example, the commonality may have a frequency of occurrence among the user profiles of the other users that is greater than the frequency of occurrence among user profiles associated with a larger population. In other examples, a first portable computing device may receive profile information from a nearby second portable computing device for determining a compatibility between a first user profile and a second user profile.

Abstract: Content items, such as e-books, audio files, video files, etc., may be recommended to a user based on the user's presence at a geolocation or venue. Geolocation is the geospatial location of the user, while a venue is a designated area for an activity, such as a concert hall, aircraft, waiting room, etc. The recommendations may be of content items relating to the geolocation or venue, or they may be content items being accessed by others who are, or have been, in approximately the same geolocation or venue.

Abstract: Character identity recognition is applied to identify text strings corresponding to character identities in a written work. The textual strings are grouped according to character identity and, from each group, a primary name is selected. A significance value may be calculated for each of the character identities. The character identities including the primary names are presented in a catalog based on the calculated significance values.

Abstract: In some implementations, a digital work may include a plurality of objects that may be selected to view supplemental information. A supplemental information user interface may include a listing of objects from the digital work. For instance, the listing may include a selected object appearing at an identified location in the digital work. The user interface may further present a visual representation displayed with each object that provides an indication of at least one location of at least one occurrence of the corresponding object in the digital work. In some examples, a user may navigate between a supplemental information view user interface, a page view user interface, a chapter view user interface, a book view user interface, a series view user interface, and/or a library view user interface to view occurrences of a particular object in the digital work or other digital works.

Abstract: A method is provided for presenting a written work. A character identity is recognized within a written work. Presentation information for the written work, such as a graphical scheme or an electronic voice, is determined based on the character identity. The presentation information is provided to a user computing device. The user computing device renders the written work or a portion thereof using the presentation information.

Abstract: An electronic device may present an interface providing information related to one or more content items. For example, the interface may present representations related to a plurality of content items to indicate relative values among the content items of at least one metric. Additionally, each representation may further indicate at least one of a quality of the value of the metric or a different metric value. A user may navigate the interface to more specific or more general views for a particular metric, characteristic and/or category, and may use the interface to view more information about a selected content item. Alternatively, the representations may represent, or may be arranged according to, authors, publishers, genres, etc. In some examples, the representations may represent terms obtained from content items that satisfy one or more metrics, such as terms that occur in content items sold within a specified period of time.
