## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is a Continuation of U.S. application Ser. No. 13/793,588, filed on Mar. 11, 2013, the disclosure of which is incorporated herein in its entirety by reference.


TECHNICAL FIELD
The field generally relates to systems and methods for customizing an electronic document, and in particular, to systems and methods for enhancing electronic book (e-book) and smart phone readers by the automatic creation of visual use marks and simulated page-flip delays and detents, which enable users to find and remember content in documents such as e-books.
BACKGROUND
An electronic book (e-book) is a book-length publication in digital form, comprising text, images, or both. An e-book may be produced on, published through, and readable on computers and other electronic devices. For example, e-books may be read on dedicated hardware devices known as e-readers or e-book devices, on personal computers, tablet computers and mobile phones. E-books can originate in digital form, i.e., have their initial incarnations in electronic form. In such cases, e-books may exist without any printed equivalent.
People who are accustomed to using traditional books often find and remember content in documents in an intuitive manner, for example, by recalling various visual aspects of a page, even including the degree of page use by dirt on a page, or by flipping through books and finding content. The speed of manual flipping of pages in an actual book can depend on certain factors, for example, use of the book, and the condition of pages and book spines. Delays in page flipping caused by one or more of these factors can help a user find content. Presently, no known methods exist to help individuals perform equivalent actions in e-books, whether the content resides on dedicated readers, smart phones, tablets, or other such devices.
Current technology allows users of e-book readers or other devices on which e-books can be read, to manually create simple bookmarks, which allow users to “jump” to sections of e-books. Additional known methods permit manually highlighting lines of text and annotating e-books, for example, by using a stylus.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
Exemplary embodiments of the invention will now be discussed in further detail with regard to systems and methods for customizing an electronic document, and in particular, to systems and methods for enhancing electronic book (e-book) and smart phone readers by the automatic creation of visual use marks and simulated page-flip delays and detents, which enable users to find and remember content in documents such as e-books. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
According to embodiments of the present invention, the following definitions may apply to the following terms used in this disclosure:

“reading an e-book”: the traversal and consumption of media from the pages of an e-book, digital book, or electronic book.
Embodiments of the present invention provide a system and method to enable individuals to find and/or cognitively recall favorite, important, and/or often-used sections and pages within an e-book, or other electronic document, such as, for example, an electronic magazine (e-zine), catalog (e-catalog), etc., that can be read on an electronic device. The electronic device, can include, but is not limited to, a dedicated hardware device known as an e-reader, or e-book device, or personal computers, tablet computers and mobile phones, such as smart phones.
Embodiments of the present invention automatically visually augment certain pages and cognitively assist in page location and recall through the insertion of delays (e.g., millisecond delays) and visual markers that can be sensed by a user when moving through an electronic document, such as an e-book. The visual markers can provide enhanced cognitive recognition, and in accordance with an embodiment of the present invention, may be automatically computed and inserted. Delays, for example, millisecond delays, in the flipping of pages while rapidly moving through an e-book can enable the user to locate favorite pages and sections. In accordance with an embodiment of the present invention, such delays and detents may be automatically computed and inserted.
Referring to FIG. 1, an e-book reader 102 or other electronic device used for viewing electronic documents, such as e-books, is shown. According to an embodiment, the e-book reader 102 includes a button 110 that the user may depress and hold to initiate sequential page flipping. Alternatively, a user may turn a dial or rocker 120 embedded in the device to flip pages. The rocker 120 can include a restorative spring mechanism, such that an angle of deflection of the dial or rocker and the rapidity and force of deflection are provided as inputs to the device to indicate speed of page flipping. For example, the dial or rocker 120 can be used to simulate a forceful turning of pages so that multiple pages can be turned at once. The dial or rocker can be used to initiate other behaviors, such as, for example, zooming and/or highlighting/annotating of text. In another alternative, the e-book reader 102 includes a screen 130 that is a touchscreen responsive to pressure and movement from the fingers of a user to flip pages, wherein a faster rate of hand or finger movement by the user results in faster or multiple page flipping, and wherein certain movements or pressures of fingers on the screen can result in zooming or highlighting/annotating of text.
Referring to FIG. 2, a system 200 for customizing an electronic document, according to an embodiment of the present invention, includes an e-book reader 102 or other electronic device that can be used for viewing the electronic documents. The system further includes a user-behavior tracking module (UBTM) 210, which records and monitors user interactions with the e-book to determine areas of interest in the e-book, and a page-behavior module (PBM) 212, which determines appropriate page behavior parameters for each page (e.g., delays or probabilities of appearance after multiple page turns) based on information recorded by the UBTM 210. A display module 214 implements the calculated behaviors determined by the PBM 212, to present pages based on calculated timing of page turns, and on probabilities of pages appearing after automatic multiple page turns. The display module 214 includes a marking engine 218 electronically coupled thereto, which graphically marks certain pages of the electronic document based on use information recorded by the UBTM 210, so that the pages deemed to be of interest contain elements of differentiation. The information recorded by the UBTM 210 can be stored in a database 216. The system may further include a settings module 220, which inputs settings, such as pre-defined user settings, to the display module, including the marking engine, regarding settings for delays, detents and/or graphical markings that have been pre-defined by a user, author, manufacturer, etc.
According to an embodiment, the components 210, 212, 214, 216, 218 and 220 of the system can be included in an e-reader 102 or other device for reading the electronic documents. Alternatively, the components 210, 212, 214, 216, 218 and 220 can be located in some remote facility, for example, a cloud computing facility or service facility communicatively coupled to the e-book reader 102.
According to an embodiment of the present invention, the marking engine 218 or other module graphically marks certain pages of the electronic document so that they contain elements of differentiation. These elements may include, but are not limited to, electronic representations of dirt, smudges, stains, hairs, rips, folds, coffee spills, cup rings, dust, browning on edges, and/or other such use indicators. Such marking can make an electronic document, such as an e-book, customized and appear more like a physical book or publication. The markings can also serve as a cognitive enhancement, enabling users to more easily remember where information may lie in the document.
In accordance with an embodiment of the present invention, the graphical marking is performed automatically by a module, such as marking engine 218 based on, for example, randomness, algorithms, user preferences, author preferences, publisher preferences, controlled elements, thresholds, and/or tracking or monitoring of use by a primary reader or many readers recorded by the UBTM 210. Algorithms, user preferences, author preferences, publisher preferences, controlled elements, and/or thresholds can be programmed via and stored in the settings module 220, which is electronically coupled to the marking engine 218. According to embodiments of the present invention, the marking or simulated visual degradation can evolve with, for example, how many times a user turns a page, eye tracking to determine what or where a user is reading, using, for example, biometric sensors, mouse tracking, and/or other such environmental factors which can be tracked by the UBTM 210. According to an embodiment, in the area of education, the marking or simulated visual degradation may serve as a cognitive aid in an electronic learning (e-learning), online education, and/or electronic textbook (e-textbook) domain, allowing learners (e.g., students) to more intuitively recognize material they have studied. In addition, implementation of the embodiments of the present invention can lead to people purchasing or using e-books who do not ordinarily like the non-physical features of e-books.
According to embodiments of the present invention, usage marks, such as, for example, smudges, which can be in the spirit of PHOTOSHOP filters, can be pre-programmed to accumulate based on use, and/or can be user-defined via the settings module 220. As an electronic document or e-book is used, and such use is recorded by the UBTM 210, a build-up of use print can be simulated via display module 214 and marking engine 218. As a result, a user can remember what is most read by such interactive traces. For example, the display module 214, including the marking engine 218 can alter cumulatively the appearance of the document by adding the usage indicators, which accumulate based on use. According to an embodiment, the cumulative alteration is a function of a variable measure of a user's interaction with the document over a range, the range being, for example, a number of times a user turns and/or turns to a page, a time period that a user spends at a page, a number of times a page was viewed by the particular reader or other readers, a number of annotations a particular reader or others have placed on the page and/or an amount of zooming and/or re-reading that has been performed on a page. According to an embodiment, cumulative changes in appearance can be weighted by a variable x: 0.0>x>1.0 and accumulate based on this variable measure of usage and interest. In the case of appearance, dirt, smudges, browning and/or stains, for example, accumulate stepwise as x grows from 0 to 1.
In accordance with an embodiment, the markings and/or delays can be tailored to multiple people reading the same book. For example, a system can learn via recording by the UBTM 210 and/or be programmed to add markings or delays via the settings module 220 according to each user's cognitive style and/or use history. The document or e-book, when opened for a particular user or group of users, can have different markings and/or delays than when opened for another user or group of users. Also, in accordance with an embodiment of the present invention, the PBM 212 can map aggregate behavior for more than one individual to a single book. Other readers may, for example, be in a user's social network, or other users who have bought and read the book. The nature of the differentiation elements can be persistent across the different electronic devices used for viewing the electronic documents or left on a primary device, and not conveyed when moving the digital representation to new devices.
In accordance with embodiments of the present invention, delays associated with simulated book page flipping on an e-book reader or other electronic devices that can be used for viewing the electronic documents can be automatically introduced by computing a page delay time based on one or more of: (1) the amount of time a reader and/or other readers have spent on the page; (2) the number of times a page was viewed by the particular reader or other readers; (3) the number of annotations the particular reader or others have placed on the page; and/or (4) the amount of zooming and/or re-reading that has been performed on a page. It is to be understood that this is not an exhaustive list, and other factors may be used to compute delay factors. In accordance with embodiments of the present invention, the features for computing delay factors can be recorded by the UBTM 210, computation can be performed by the PBM 212, and implementation of delay factors can be performed by the display module 214.
According to embodiments of the present invention, a delay factor can include one or more of: (1) a time delay (e.g., quarter-second); (2) detent; and (3) a sound to accompany the page delay. In physical terms, a “detent” can refer to a method or device used to mechanically resist or stop rotation of a component, such as a wheel, axle or spindle or other related moving element, and has been used to divide a rotation or movement into discrete increments. For example, detents can be responsible for the “clicking” and tactile feel when rotating certain dials. In the case of embodiments of the present invention, a detent relates to a vibrational component corresponding to certain locations in an e-book or other electronic document in order to give a user tactile feedback while “flipping” through pages via, for example, a finger or hand motion on a touchscreen of the device on which the electronic document is presented.
According to embodiments of the present invention, the detents (e.g., detent intensity) can vary as a function of the various conditions described herein such as, for example, the amount of time a reader and/or other readers have spent on the page, the number of times a page was viewed by the particular reader or other readers, the number of annotations the particular reader or others have placed on the page, and/or the amount of zooming and/or re-reading that has been performed on a page.
Additionally, like the delays, graphical indicators of use applied across a page can automatically be added to pages of an electronic document, by computing a page usage factor based on one or more of: (1) the amount of time a reader and/or other readers have spent on the page; (2) the number of times a page was viewed by the particular reader or other readers; (3) the number of annotations the particular reader or others have placed on the page; (4) the amount of zooming and/or re-reading that has been performed on a page. It is to be understood that this is not an exhaustive list, and other factors may be used to compute usage. In accordance with embodiments of the present invention, the features for computing usage can be recorded by the UBTM 210, computation can be performed by the PBM 212, and implementation into graphical indicators can be performed by the display module 214 and marking engine 218.
In accordance with an embodiment of the present invention, a page or pages of an electronic document can be designated as areas of interest if a user, for example: spends more time on a page(s) or visits a page(s) more often than others, has electronically annotated the page(s), and/or implemented a zoom gesture on the page(s). It is to be understood that the preceding are exemplary in nature and are not intended to limit the types of activity that may indicate interest in an area of the document.
According to an embodiment, a drawn spine of a book is visually augmented to indicate more use than other pages, imitating a book that is laid open for a long period of time on a particular page. The image of the book at the particular page shows the text as shifted farther away from the spine than on other pages that have been used less than the particular page to indicate the tendency of the book to stay open at the particular page. The appearance of the shifted text can enhance cognitive recognition by the user. According to an embodiment, the visual marking may be extended to an image of the outside spine of the book to show creases at or near areas of interest. For example, the outside of books can be rendered on a reader in three dimensions during selection, showing a bookshelf on which the books are placed. In this rendering, the outside of the spine(s) can be marked with creases to indicate the areas of the most interest. As a result, a user can select a book off a virtual shelf, have an indication of what general location in which the areas of interest reside, and fine tune the page movement to sections that contain the areas of interest. Any combination of the PBM 212, display module 214 and/or marking engine 218, based on input from the UBTM 210 and/or settings module 220, can be used to implement the referenced features in connection with the spine.
According to an embodiment, pauses, for example, measured in some number of milliseconds, are inserted between pages to appear during page turning in an e-book to assist users in locating sections of interest. For example, during rapid page turning, when the system updates a page display, the system will insert a small pause at a previously marked or noted area of interest before moving on to the next page. This momentary pause will be long enough such that the user can recognize the page at the area of interest and stop the page movement, or revert to the last rendered area of interest. In another embodiment, when flipping stops, the e-book or other type of electronic document may open to the next available page that has the most use to simulate a situation where a physical book may be prone to open to a highly read or often used page. Any combination of the PBM 212 and/or display module 214, based on input from the UBTM 210 and/or settings module 220, can be used to implement the referenced features in connection with pauses.
Like with the appearance of the document, the display module 214 can alter cumulatively the behavior of the document by adding elements which accumulate based on use, for example, pauses, detents, and/or an increase in the probability of landing on a page after multiple page flips. According to an embodiment, the cumulative alteration is a function of a variable measure of a user's interaction with the document over a range, the range being, for example, a number of times a user turns and/or turns to a page, a time period that a user spends at a page, a number of times a page was viewed by the particular reader or other readers, a number of annotations a particular reader or others have placed on the page and/or an amount of zooming and/or re-reading that has been performed on a page. According to an embodiment, cumulative changes in behavior can be weighted by a variable x: 0.0>x>1.0 and accumulate based on this variable measure of usage and interest. In the case of behavior, pauses, detents, and/or an increase in the probability of landing on a page after multiple page flips, for example, accumulate stepwise as x grows from 0 to 1.
Referring to FIG. 3, in a method for customizing an electronic document, according to an embodiment of the present invention, a user interacts with an e-book reader 102 (or related document viewer) by performing one or more actions to indicate an area(s) of interest. For example, over a predetermined time interval, or over a predetermined number of uses, demarcated by the user closing the e-book and/or turning off the e-book reader, a user may, for example, leave an e-book open on a first page for 30 seconds, on a second page for 100 seconds, and not spend any time on a third page. The user may also magnify a portion of and highlight several sentences on the second page.
At block 302, the system monitors user interaction with the e-reader 102 or other device used for reading electronic documents. If the user does not perform any actions to indicate areas of interest at block 304, the system, for example, the UBTM 210, continues to monitor and the method returns to block 302. If the user performs actions to indicate areas of interest at block 304, the UBTM 210 records the user actions (block 306) and stores the information in the database 216 (block 308). A record of the information stored in the database 216 may include information such as D(p,d,m,h)=(20, 100, 3, 30), where D represents a multidimensional vector, p is the page number, d is the amount of time that the page was displayed, m is the number of times the page was magnified, and h is the number of words that were highlighted on the page. Accordingly, for example, (20, 100, 3, 30) indicates that page 20 was displayed for a period of 100 seconds, magnified three times, and had 30 words highlighted. According to an embodiment, the 100 seconds refers to 100 seconds while the user was actually touching the device, for example, holding the device, so as to avoid accumulating durations in which the device is left unattended and open to a page, and the user is not interacting with the material. The fact that a user is interacting with a device can be determined by various means, including pressure sensors, or other biometric sensors coupled to the device. A measure of user interaction with a device may be a moving average over a set time interval or number of uses. Measures of interaction may be recorded and calculated by components of a system, for example system 200, on the e-book reader itself, or in some remote facility, for example, a cloud computing facility or service communicatively coupled to the e-book reader.
In a further step at block 310, the PBM 212 mathematically maps the information contained in multidimensional vector D to actual behavior of the pages to be displayed on screen 130. The mapping may be calculated by components of a system, such as system 200, on the e-book reader itself, or in some remote facility, for example, a cloud computing facility or service communicatively coupled to the e-book reader.
At block 312, based on settings and the user interaction with particular regions, pages or groups of pages, graphical indicators are applied to page(s) of interest. In addition, based on settings and the user interaction with particular regions, pages or groups of pages, the mapping can lead to the calculation of probabilities that pages will appear after multiple page flipping (block 314) and/or creation of a distribution of page delays to be implemented when flipping through e-book (block 316). The changes to the page(s) are implemented in connection with a user flipping through and/or viewing the page(s) (block 318), and the system can continue to monitor further user interaction with the e-reader.
In accordance with an embodiment, in connection with block 316, B(p)=|D(p,d,m,h)|*N provides a mapping, where B(p) is a sub-second delay for page p (e.g., 30 milliseconds (but not limited thereto)), and N is an adjustable scale factor. The behavior may be altered such that the larger the deflection of the dial or rocker 120, or a functionally equivalent action on another mechanism for increasing the rate of flipping pages, the more rapid the rate of page flipping, while the time spent on any page during page flipping is an inverse proportion of the rate of flipping.
If a flipping rate is 50 pages per second, the average time per page is 20 milliseconds, and the PBM 212 can create a distribution of actual page delays with a standard deviation of ±5 milliseconds. The PBM 212 may also directly map information from D to the probability that a particular page will appear after automatic multiple page flipping (block 314). Fast, forceful deflections of the dial or rocker, or a functionally equivalent action on another mechanism for increasing the rate of flipping pages, may provide the input to the device resulting in multiple page turns. For example, such a forceful gesture by a user on a dial, rocker or touchscreen can result in simultaneously turning several pages, like grabbing multiple pages in a physical book, to advance to subsequent pages. Based on the use data gathered by the UBTM 210 from monitoring users to determine areas of interest, a next page displayed or landed on after multiple page turns can be a highly used/visited page that has been deemed an area of interest. Depending on settings, the force of the gesture and/or level of use of a page, the reader or device on which the document is read can stop or slow down at the page designated as an area of interest after multiple page turns are made. Pages are rendered in a distorted form as they are flipped, for example, by shearing, pinching, blurring, or otherwise altering the text.
Parameterized physical models may be used to mathematically map the information contained in multidimensional vector D to actual behavior of the pages to be displayed on screen 130, such as the model discussed in connection with FIG. 4 herein, in which the delays and probabilities for each page are a function of neighboring pages, as in a system of coupled springs.
A method for customizing an electronic document, according to an embodiment of the present invention makes use of a physical analogy of a system of virtual elastic springs modeled as a set of couplings between virtual components of an electronic document (such as, for example, pages, regions of pages, and words of an e-book). According to the model, pages, regions and/or words are coupled to each other via virtual springs between the components and to a rigid framework via virtual springs between predetermined components (e.g., end pages) and the rigid framework. The elastic coefficients of the couplings of this system are adjusted based on user interaction with the e-book, which are referenced by the model when a user flips pages or examines a page, to determine probabilities of a page or region appearing, and a time interval over which a device used for e-reading displays the page or region.
Referring to FIG. 4, the method for customizing an electronic document, according to an embodiment of the present invention, includes storing elastic coefficients for linkages between every page to a level of granularity determined by an amount of memory available to model the e-book as a system of springs (block 404). According to an embodiment, elastic coefficients between parts of a page can also be stored. All coefficients are set to the same initial value (block 402) so that when a user first flips through the e-book, all pages and page regions pause with equal probability and identical time intervals, as determined by the physical model of the traversal of spring-coupled masses.
Like the method described in connection with FIG. 3, the system monitors user interaction with the e-reader 102 or other device used for reading electronic documents (block 406). If the user does not perform any actions to indicate areas of interest at block 408, the system, for example, the UBTM 210, continues to monitor and returns to block 406. If the user performs actions to indicate areas of interest at block 408, the UBTM 210 records the user actions. For example, when a user pauses on a page, zooms to a particular region for reading, or performs any other action through which the page or particular region will be deemed an area of interest, the spring coefficients coupling the page or region which is the area of interest to other pages, and the page to the rigid framework upon which the system rests, are increased (block 410) and stored (block 412). The increases are proportional to, for example, the amount of time the user spends reading the page or region, the number of times the page or region was viewed by the user, the number of annotations placed on the page or region, and/or the amount of zooming and/or re-reading that has been performed on the page or region. When a user flips through the e-book a second or subsequent times, pages and regions that have been perused recently pause with greater probability and longer time intervals, as determined by a model of the traversal of spring-coupled masses using the newly modified elastic coefficients (block 414), and the system can continue to monitor further user interaction with the e-reader.
According to an embodiment, elastic coefficients can decay back to their initial values over a predetermined time period chosen by, for example, the user, the manufacturer of the e-book reading device, or the publisher of the e-book. According to an embodiment, the spring system can be modeled using Hooke's Law:

F=kx  (1),

where F is the force determining how likely a page or region appears, k is the elastic coefficient, and x is the current “displacement” of the page or region from a rest point of the page or region, due to a user flipping pages and/or examining regions and due to interaction from other pages or regions.
Embodiments of the present invention can also be applied to situations where advertisers in an electronic publication, such as, for example, an e-zine, wish to pay publishers to introduce delays in pages so that when a user is leafing through the e-zine, the pages with advertisements have delays (e.g., sub-second delays) so as to catch a user's attention. In addition, according to embodiments of the present invention, use patterns of certain users may be packaged or otherwise distributed to other e-book readers or devices to allow users to learn how others have read the same book, and utilize the use patterns of others. According to embodiments, the use patterns may come from individuals in similar fields or members of the same social network as the recipient. The use patterns of others can be stored in predetermined profiles, and can be applied to the e-books of recipients at their option. Further, use patterns derived from a user's interaction with an e-book can be translated into other media, such as, for example, study guides, tests, or other educational material.
