A method for managing engagement and presentation content of an electronic document involves providing container metadata identifying engagement containers within the electronic document, providing engagement data linked to the engagement containers, the engagement data comprising parameters of an engagement based on the segments of content in the linked engagement containers, executing a procedure to traverse engagement containers identified in the container metadata. The procedure includes accepting, based on user input, data responsive to the engagement, and assigning a score for the current engagement container based on the received data and the parameters defined in the engagement metadata.

A book (1) is described. The book has front and back covers (2, 3) and a plurality of pages (5) bound between the covers. The book includes capacitive touch elements (9) disposed on the inside (10, 14) of the back cover and/or the front cover. The book also includes at least one output device (7), such as a speaker, and a controller (18). The controller is configured to cause the or at least one of the output devices to output a signal in dependence upon position of a user's digit (31: FIG. 6) on a page overlying the cover.

A graphic recognition-based interactive method and electronic device. The interactive method comprises: acquiring a first image to be analyzed (101); recognizing the first image to be analyzed to obtain a recognition result (102); playing a narration audio file associated with the recognition result (103); playing a question audio file associated with the interactive content of the first image to be analyzed based on the recognition result after the narration audio file is played (104); acquiring a second image to be analyzed (105); determining whether a feature graphic exists in the second image to be analyzed (106); if the feature graphic exists in the second image to be analyzed, determining whether the feature graphic overlaps with an interactive region, wherein the interactive region is an area corresponding to an answer to the question in the question audio file (108); playing a correct audio file if the feature graphic and the interactive region are overlapped (109); and playing a wrong audio file if the feature graphic and the interactive region are not overlapped (110). The said method provides increased interactivity.

An asynchronous content delivery system is provided that pushes messages or notifications of content designed for spaced repetition. Machine learning may be used to create, select and prioritize the messages/notifications. The asynchronous content delivery system may support asynchronous promotion of the content to the user. The asynchronously delivered content may be at least partially derived from a conversation agent operating on a user device. In another example, the content may be created or selected independently by a plurality of content providers and artificial intelligence algorithms. The content may be classified in sets according to a set of rules of combination. The content may be asynchronously delivered to end user devices according to a set of rules of delivery. The rules of delivery may influence a manner in which the content, or a representation thereof, is manifest on the end user devices.

In an example, printed circuitry comprises a digitally printed switch, the printed switch comprising a first contact element printed using conductive print agent on a first substrate portion and a second contact element printed using conductive print agent on a second substrate portion. An interposed non-conductive printed spacer element is overprinted on at least one of the first and the second substrate portions.

A finger reading method and device based on visual gestures. A user makes a circle on a required finger reading region on a book by using a finger; a camera captures the circle making action of the finger, and an image processing module acquires the position a fingertip according to a profile analysis algorithm, acquires the endpoints of the track edge in upper, lower, left and right directions, and fits a rectangle according to the upper, lower, left and right end points in order to identify content such as characters or graphs of rectangular region content. A voice synthesis technology is performed. Voice information is fed to the user to realize a finger reading functions. The device can be worn on the head of the user, and includes camera and bone conduction earphones arranged on both sides thereof.

The disclosure provides technology for enhancing the ability of a computing device to detect when a user has discontinued reading a text source. An example method includes receiving audio data comprising a spoken word associated with a text source, wherein the audio data comprises a first duration and a second duration; comparing the audio data with data of the text source, wherein the first duration of the audio data corresponds with the data of the text source; calculating, by a processing device, a correspondence measure between the second duration of the audio data and the data of the text source; and responsive to determining the correspondence measure satisfies a threshold, transmitting a signal to cease comparing audio data with the data of the text source.

An online educational system for learning the core subjects of mathematics, social science, the sciences and English in a supportive curriculum via a universal learning design model is provided. The system breaks each subject down into sub-modules and bundles the courses for the sub-module, allowing a user to logically progress therethrough, although the user can select courses in any desired order. Each course is presented in visual, audio-visual or audio only fashion and can include sign language and text to speech functions. A user can take electronic notes within a course, can user portions of a course to create a POWERPOINT-type presentation for others, and can e-mail a teacher for questions with content specific information inserted into the e-mail to the teacher to provide specific subject matter content.

The disclosure includes a multi-media book system. An embodiment of the system can include a book system. The book system includes both an open and closed configuration. The book system includes a cover device and a book device. The book device is configured to fit inside of the cover device. Both the cover device and the book device are configured to function like a book and can include pages. These pages can be coupled to a binding or spine of the book device, separate from the cover device. The cover device includes a cover interior surface and a cover exterior surface. The book device includes a book interior surface and a book exterior surface. The book exterior surface is configured to mate with the cover interior surface via a magnetic coupling.

A method is described herein comprising obtaining a soundcard comprising an audio device with guidance for at least one of the following: breathing, visualization, and muscle relaxation, and generating an audio output by opening the soundcard. Corresponding systems and devices also are disclosed.
