    Abstract: Devices, systems and methods are disclosed for anchoring bookmarks to individual words for precise positioning within electronic documents. The bookmarks may be anchored based on user input selecting particular words, based on gaze tracking identifying most recently read words, or based on estimated reading speed. The bookmarks may be a link used to navigate within the document, may be used as an anchor for a new layout after content reflow or may be automatically saved when the e-reader turns off the display to provide the user with a most recently read passage. If a bookmark isn't anchored to specific words by the user, the device may anchor the bookmark to the beginning of a sentence or a paragraph including the recently read words determined using gaze tracking or estimated reading speed.

    Abstract: Systems, methods, and computer-readable media are disclosed for dynamic character enhancement for rendering digital content. Example methods may include identifying a reading speed indicative of a rate at which a user desires to read, determining a number of words in a portion of content to present to the user, and determining a base time interval for at least one word of the portion of content based at least in part on the reading speed. Methods may include determining an average difficulty value of the portion of content, determining that a first difficulty value of a first word exceeds the average difficulty value, and determining a first time adjustment for the first word based at least in part on the first difficulty value. Methods may include determining a first time interval based at least in part on the base time interval and the first time adjustment.

    Abstract: A rendering optimizer captures content engagement feedback associated with a first interval during which electronic content is presented with a first set of rendering parameter values. The rendering optimizer adjusts at least one rendering parameter value of the first set of rendering parameter values by a step amount in a first direction to create a second set of rendering parameter values and captures content engagement feedback associated with a second interval during which the electronic content is presented with the second set of rendering parameter values. The rendering optimizer further adjusts the rendering parameter values to determine they result in an improvement in reading immersion.

    Abstract: A method and system to provide fonts for electronic publications is described. An example method includes receiving a request for an electronic publication from a user device, retrieving a font identifier of a font from the electronic publication, providing the electronic publication to the user device, determining, based on the font identifier, that at least one font file of the font is not stored on the user device, and providing the at least one font file of the font to the user device.

    Abstract: Methods and systems for rendering text to simulate human penmanship are described. A text rendering engine converts a text string into an image that can be displayed using one or more seed numbers to influence the rendering and appearance of the text. The text rendering engine may render variations of each character of the text string using the seed numbers to select from a set of single-character or multi-character glyphs, or to modify a size, weight, slope, or Bezier curve point of the character.

    Abstract: Devices and techniques to incrementally update content associated with an electronic publication are described. A patch generation module may be configured to generate patch data files comprising incremental changes associated with the electronic publication. A differential patch module located on a client device may be configured to obtain the patch data files. The differential patch module may also be configured to compare the patch data files and the electronic publication and identify the differences between the files. Additionally, the differential patch module may be configured to update the changes in the patch data files with the content of the electronic publication. Accordingly, the electronic publication may be updated to include the changes in the patch data files.
