Abstract: Techniques and systems described herein locate possibly-significant portions of electronic documents. In some examples, gaze movements, e.g., of users' eyes, are tracked while the users read a formatted version of an electronic document. The gaze movement may be analyzed to determine if a reading interruption occurs (e.g., a reading pause or irregularity in a regular reading rate for the user). The reading interruption may occur when the user, while reading, encounters or notices a problem or point of interest in the text. A reading location associated with the reading interruption may be determined in text that is currently displayed. The reading location may be mapped to a location in a standard version of the document. The location may be reported to a centralized entity where statistical analysis can be performed to determine if there is a problem in the document.

Abstract: Various embodiments enable a media playback device to present a user with the option to add items referenced in a media object, such as a movie, ebook, song, game, or application, to a wishlist for later purchase or sharing. An example system performs content analysis of the media object to determine which items are referenced in the media object and where they are located within the media object. Further, the system can query an electronic marketplace for more information about which specific types, sizes, colors, or other variations of the item are available, as well as information such as price, shipping cost, shipping time, and so forth. In a video media object, for example, the system can present a custom miniature storefront for various scenes or frames in the video that represents items present or referred to in the scenes or frames.

Abstract: The techniques and systems described herein track gaze movement of a user while eyes of the user read a document on a computing device. The techniques may then analyze or evaluate the gaze movement to determine if a reading interruption occurs (e.g., a reading pause or irregularity in a regular reading rate for the user). The reading interruption may occur when the user, while reading, encounters or notices a problem in the text. The reading interruption may also occur when the user encounters or notices text that the user has a strong interest in. When the reading interruption occurs, the techniques may evaluate a gaze direction and associate the reading interruption with a text that is currently displayed (e.g., word, sentence, paragraph, page, etc.). Moreover, the techniques may map the displayed text to a location in the document (e.g.

Abstract: The techniques and systems described herein place product information at a location in digital content where an existing object occurs. The techniques may select the product information based on profile data indicative of interests of a user viewing the digital content. Accordingly, the techniques may identify existing objects in the digital content before the user begins viewing the digital content. The techniques may also receive or access product information to be placed in the digital content. The product information may include identifiable brands, products, or services. Then, while rendering the digital content before the user begins viewing the digital content or while the user is viewing the digital content, the techniques may select product information to dynamically place into a scene of the digital content at a location where the existing objects occur.
