A book made up of pages is described. At least some of the pages contain both space for manually-created visual content, and instances of preprinted indexing target symbols. Each of the indexing target symbol instances has at least a portion within one inch of three unbound page edges. When the book is closed, the instances of each particular indexing target symbol are in a substantially collinear stack that is substantially perpendicular to the faces of the pages.

A method of detecting a user interaction by an electronic device according to various embodiments may include acquiring, through a camera, a first image of a real document in which at least one first area is printed, determining whether at least one first part corresponding to the at least one first area and included in the first image is changed, and performing a function of the electronic device corresponding to the at least one first part, based on determining that the at least one first part is changed.

Methods, systems, and media for enhancing one or more publications by receiving live video captured by a user, the live video comprising video of a publication, the publication comprising copyrighted content; identifying at least one first trigger in the live video, identifying one or more first three-dimensional, interactive media associated with the at least one first trigger and pertaining to the copyrighted content, and presenting to the user the first three-dimensional, interactive media; and identifying at least one second trigger in the first three-dimensional, interactive media, identifying one or more second three-dimensional, interactive media associated with the at least one second trigger and pertaining to the copyrighted content, and presenting to the user the second three-dimensional, interactive media to progressively deepen and enrich the engagement with the copyrighted content of the publication.

Disclosed are a reading support apparatus which can detect a user input (touch and/or drag) conducted on a real book by using one camera, and a user input detection method using the same. The reading support apparatus sets a finger and/or nail on a target surface image captured through one camera to touch recognition reference, detects, as a user input, a user's touch or drag conducted on the surface of the real book by comparing the finger and/or nail included in the target surface image to the touch recognition reference, and provides an action corresponding to the user input.

Methods, systems, and media for enhancing one or more publications by receiving live video captured by a user, the live video comprising video of a publication, the publication comprising copyrighted content; identifying at least one first trigger in the live video, identifying one or more first three-dimensional, interactive media associated with the at least one first trigger and pertaining to the copyrighted content, and presenting to the user the first three-dimensional, interactive media; and identifying at least one second trigger in the first three-dimensional, interactive media, identifying one or more second three-dimensional, interactive media associated with the at least one second trigger and pertaining to the copyrighted content, and presenting to the user the second three-dimensional, interactive media to progressively deepen and enrich the engagement with the copyrighted content of the publication.

Provided is an image reading system that divides, with respect to image data obtained by performing a double sided reading in a state where a booklet is opened, cover sheet image data into two parts corresponding to a pair of cover sheets to arrange the two parts at a front and an end, respectively, and arranges main text image data between the front and the end, and then generates an image file from each of the arranged image data.

Methods, systems, and media for enhancing one or more publications by receiving live video captured by a user, the live video comprising video of a publication, the publication comprising copyrighted content; identifying at least one first trigger in the live video, identifying one or more first three-dimensional, interactive media associated with the at least one first trigger and pertaining to the copyrighted content, and presenting to the user the first three-dimensional, interactive media; and identifying at least one second trigger in the first three-dimensional, interactive media, identifying one or more second three-dimensional, interactive media associated with the at least one second trigger and pertaining to the copyrighted content, and presenting to the user the second three-dimensional, interactive media to progressively deepen and enrich the engagement with the copyrighted content of the publication.

A book detection apparatus detects a plurality of surface regions on the basis of three-dimensional measurement data that is obtained by a three-dimensional sensor and that falls within a search area, and determines, when a positional relationship between two surface regions among the plurality of surface regions satisfies a positional condition corresponding to a positional relationship between two opened pages of an opened book, the two surface regions as a book region that includes the book.

A book made up of pages is described. At least some of the pages contain both space for manually-created visual content, and instances of preprinted indexing target symbols. Each of the indexing target symbol instances has at least a portion within one inch of three unbound page edges. When the book is closed, the instances of each particular indexing target symbol are in a substantially collinear stack that is substantially perpendicular to the faces of the pages.

The present techniques generally relate to an apparatus for determining user progression data in a literary work, the apparatus comprising: a database comprising formatted literary data for two or more versions of a literary work; and circuitry to: process tracker position data for a first version of the one or more versions; and determine, from formatted literary data for the two or more versions, progression data for a second version of the literary work based on or in response to the tracker position data for the first version.
