A menu containing the most recently read items is separated into separate categories such as books and periodicals. The menu displays the most recently opened item in each of the categories. In this manner, one category will not dominate over the other categories on the menu.

## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims benefit under 35 U.S.C. §119(e) from U.S. Provisional Patent application No. 61/407,006, filed on Oct. 26, 2010, the entirety of which is incorporated by reference herein.


FIELD OF THE INVENTION
The present invention generally relates to systems and methods for organizing user interfaces, and more particularly to systems and methods for organizing a user interface on a mobile electronic book reader.
BACKGROUND OF THE INVENTION
There are several conventional methods of displaying items such as files that were most recently used by a user. For example, word processors traditionally keep track of and are capable of displaying a list of the last few documents on which a user has worked. Web browsers are similarly capable of providing users with a list of the last few websites visited.
SUMMARY OF THE INVENTION
The present invention provides a user with a listing of the most recently used or viewed items that is organized by the category of item. In a preferred embodiment, the present invention is used in an electronic reader. The menu containing the most recently read items is broken down, by books and periodicals, or by books, newspapers and magazines. The menu displays the most recently read item in each of the categories. In this manner, one category will not dominate over the other categories.
For example, since a typical reader reads more periodicals than books during a given period, without the present invention, the menu of most recently read items would be dominated by the periodicals. Specifically, as most newspapers are read on a daily basis, the user's newspaper editions would dominate a “Most Recently Read” list, and the book she has not opened in more than two weeks would easily drop off the list.
By organizing the most recently read list by category, a user can quickly locate the items she has most recently read. For example, the book she has most recently read is found at the top of the Book category. The magazine she has read is at the top of the Magazine category. The newspaper she has most recently read is at the top of the Newspaper category. The file she has most recently looked at is at the top of the File category.
As appreciated by those skilled in the art, any number of categories can be established. Multifunctional devices can further include categories such as Music, Video, Audio books. Within music, sub-categories can be established, e.g., Rock, Rap, Blues or Show tunes. Within each of these categories, the most recently listened to material would appear at the top of the category or subcategory list.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows components of digital content control system in which the present invention can operate. User 105 is an authorized user of the digital content control system of the present invention. Many of the functions of digital content control system are carried out on digital content control server 150. As appreciated by those skilled in the art, many of the functions described herein can be divided between the digital content control server 150 and the user's local device 130. Further, as also appreciated by those skilled in the art, digital content control server 150 can be considered a “cloud” with respect to the user 105 and his local device 130. The cloud can actually be comprised of several servers performing interconnected and distributed functions. The user 105 can connect to the digital content control server 150 via the Internet 140, a telephone network 145 (e.g., a wireless cellphone network) or other suitable electronic communication channels. User 105 has an account on digital content control server 150, which authorizes user 105 to use the digital content control system.
Associated with the user's 105 account is the user's 105 digital locker 120 located in a Digital Locker Database 180 on the digital content control server 150. As further described below, in the preferred embodiment, digital locker 120 contains links to copies of digital content 125 purchased or otherwise legally acquired by user 105.
Indicia of rights to all copies of digital content 125 owned by user 105 are stored by reference in digital locker 120. Digital locker 120 is a remote online repository that is uniquely associated with the user's 105 account. As appreciated by those skilled in the art, the actual copies of the digital content 125 purchased by user 105 are not necessarily stored in the user's locker 120, but rather the locker 120 stores an indication of the rights of the user to the particular content 125 and a link or other reference to the actual digital content 125. Typically, the actual copy of the digital content 125 is stored in another mass storage (not shown). The digital lockers 120 of all of the users 105 who have purchased a copy of a particular digital content 125 would point to this copy in mass storage. Of course, back up copies of all digital content 125 are maintained for disaster recovery purposes.
Although only one example of digital content 125 is illustrated in this Figure, it is appreciated that the digital content control server can contain millions of files 125 containing digital content. It is also contemplated that the digital content control server 150 can actually be comprised of several servers with access to a plurality of storage devices containing digital content 125. As further appreciated by those skilled in the art, in conventional licensing programs, the user does not own the actual copy of the digital content, but has a license to use it. Hereinafter, if reference is made to “owning” the digital content, it is understood what is meant is the license or right to use the content.
User 105 can access his or her digital locker 120 using a local device 130. Local device 130 is an electronic device such as a personal computer, an eBook reader, a smart phone or other electronic device that the user 105 can use to access the digital content control server 150. In a preferred embodiment, the local device 130 has been previously associated or registered with the user's 105 account using user's 105 account credentials. Local device 130 provides the capability for user 105 to download the user's copy of digital content 125 via his or her digital locker 120. After digital content 125 is downloaded to local device 130, user 105 can engage with the downloaded content locally, e.g., read the book, listen to the music or watch the video.
In a preferred embodiment, local device 130 includes a non-browser based user interface subsystem that allows user 105 to initiate the purchase of digital content 125 in a non-browser environment. Through the device interface, the user 105 is automatically connected to the digital content control server 150 in a non-browser based environment. This connection to the digital content control server is a secure interface and can be through the telephone network 145, typically a wireless cellular network for mobile devices. If user 105 is accessing his or her digital locker 120 using the Internet 140, local device 130 also includes a web account user interface subsystem. Web account interface provides user 105 with browser-based access to his or her account and digital locker 120 over the Internet 140. Web interface allows user 105 to initiate the purchase of digital content 125 in a browser based environment. Local device 130 further includes an input output subsystem that provides the interface between the local device 130 and the remote server 150. Local device 130 also includes an operating system that is operable to control the operations of the local device 130.
FIG. 1 further illustrates the detailed components of digital content control server 150. Digital content control server 150 handles front-end functions related to web server operations and user interactions with the web and device interfaces in connection with the user's local devices 130. Digital content control server 150 also handles all backend functions related to managing accounts, maintaining digital locker records, maintaining content metadata and providing encryption services.
Digital content control server 150 provides both the browser based web interface and the non browser based device interface. User 105 may engage with the web interface or the device interface to initiate a purchase.
Digital content control server 150 employs web server 160 including web services interface software 170 to handle interactions between front-end components, such as device interface, web account interface, and web interface, and back-end database components of the system. Web server 160 services include serving up the web pages 165 that comprise the web account interface and the web interface, and the underlying web services associated with the device interface. Web services interface software 170 includes handling users' logins to their accounts and processing the initiation of and response to purchase requests.
Back-end database components of digital content control server 150 includes customer accounts database 175, digital lockers database 180, and content metadata database 135. Records for users' accounts are stored and managed in customer accounts database 175. Records for digital lockers 120 are stored and managed in digital lockers database 180. Content metadata database 135 serves as a source of metadata for individual digital content items 125 in digital content control server 150.
Web services interface software 170 in the web server 160 interfaces with customer data services 185 to update customer accounts database 175 and digital lockers database 180. Customer data services 185 processes database updates such as maintaining and validating customer data in users' accounts. Web services interface software 170 in the web server 160 also interfaces with content encryption services 155 to secure certain communications with local device 130 and to package digital content 125 for secure delivery to user 105.
In the preferred embodiment of the invention, digital content control server 150 is an eBook and periodical digital content control system. Although the eBook and digital periodical applications are the preferred embodiment, as appreciated by those skilled in the art, the digital content control server 150 of the present invention is not limited to user 105 purchasing and using eBooks or digital publications. Digital content control server 150 can be used for purchase and use of any digital content, such as digital movies, digital music, digital audio books, digital pictures or other downloadable digital content.
In the preferred embodiment of the invention, local device 130 is a mobile electronic reader (eReader) device. The embodiment of the invention is not intended to limit local device 130 to a mobile eReader device. Local device 130 may be a desktop personal computer or another type of mobile consumer electronic device, such as, for example, a cell phone, a laptop computer, a tablet computer or other mobile digital device.
In preferred embodiment, the present invention operates on a user's local device 130. The menu or list of the present invention appears on the user interface of device 130. The ‘Recently Read’ menu has two different basic states, either opened or closed. The closed state menu 210 is illustrated in FIG. 2A. In a preferred embodiment, the menus of the present invention appear in the corner on a home screen 200 on the device. The home screen 200 can be the basic home screen of the device 130, the home screen on the native reader application, or the home screen of other applications.
In the closed state menu 210, the most recently read item 220 in any category is listed in the menu 210. In order to open and read this item 220, the user simply taps (assuming a touch screen) on the item 220 to open it. In a preferred embodiment, the item 220 is opened to the last page that was being viewed by the user 105. Below the most recently read item 220 is a button 230, which expands the closed state ‘Recently Read’ menu 210 into the open state menu 240 as illustrated in FIG. 2B.
As shown in FIG. 2B, the open, expanded ‘Recently Read’ menu 240 on interface 200 includes categories 250, 260, for different types of materials. Category 250 is the Book category, and lists the book 220 most recently read by the user 105. In the embodiment illustrated in FIG. 2B, only the most recent book read by the user is listed, as it is less likely that the user would have two unfinished books at any given time (as opposed to two or more unfinished newspapers or magazines.) One of the functions of the present invention is to allow the user 105 to easily and quickly locate and open the material that she wants to read. This is most likely the material that she has already started reading. Tapping on the title of the Category, e.g., Books 250 opens the user's library application on device 130 to the book section, where the user 105 can view of her books. Similarly, tapping on the Periodical 260 link opens the library to the periodical section where the user can view her periodicals.
In the examples of the items read by user 105 illustrated in FIG. 2B, a hypothetical user 105 read the following items in the following order over the weekend:
“Angels & Demons” by Dan Brown
The New Yorker (April 12)
The LA Times (April 12)
The LA Times (April 13)
PC Magazine (April edition)
As shown in FIG. 2B, book 220, Angels & Demons, is at the top of the list in the Books category 250 as it was the book most recently opened by the user 105. Similarly, PC Magazine 262 is at the top of the Periodical category 260 as it was most recently read periodical. Below PC Magazine 262 the April 13th issue of the LA Times 264 is listed and then the April 12th edition of the New Yorker Magazine 266. Although the user 105 read the April 12th issue of the LA Times more recently than the issue of the New Yorker Magazine 266, in the preferred embodiment, the present invention does not list it on menu 240 since the April 13th issue of the LA Times 264 is already issued. The operating assumption is that the user can use other navigating tools from the April 13th issue of the LA Times 264 or the periodicals section of the library application to gain access to the April 12th issue of the same periodical. For example, the present invention has a “Find related items in the series” search feature. This search feature allows the user, for example, to find yesterday's newspaper while reading today's newspaper.
Button 270 can be used to collapse the open menu 240 back in the closed state 210 as illustrated in FIG. 2A. Further, tapping any place other than on menu 240 on screen 200 closes menu 240.
Continuing with the example of the hypothetical user 105, this same user continued to read the following items in this order:
“Open” by Andre Agassi
“Mastering the Art of French Cooking” by Julia Child
The New York Times (April 15)
The San Jose Mercury News (April 15)
“Act Like a Lady, Think Like A Man” by Steve Harvey
As shown in FIG. 3A, in the closed state the user's ‘Recently Read” menu 210 lists the book 300 “Act Like a Lady, Think Like A Man” by Steve Harvey as it was the last item read by the user 105. If the user 105 clicks on the expand button 230 on the closed menu 210, the reading list is expanded as illustrated in FIG. 3B. As seen in FIG. 3B, the PC magazine 262 was pushed down in the Periodical category 260 as the user subsequently read the San Jose Mercury News 268 and New York Times 269 newspapers. In the present embodiment, newspapers and magazine are both grouped in the single generic category Periodicals 260. As described above, the Periodical category 260 can further be broken down into sub-categories such as newspapers and magazines. In one embodiment, the sub-categories are configurable by the user 105.
As further shown in FIG. 3B, the Dan Brown book Angels & Demons (220 in FIGS. 2A, 2B) was pushed off the list 240 because the user had subsequently opened three other books 300, 302, 303. In a preferred embodiment, each of the categories, e.g., Books 250, Periodicals 260, has a predefined number of recently read items that it can display. In one embodiment, the number of items that can be displayed is configurable by the user 105.
As further shown in FIG. 3B, the menu 240 also includes a category for Files 310. This category 310 includes other types of items such as pdf or rtf files or other types of files that can be opened and accessed by the user 105 using the device 130.
Some of the rules adopted for formatting the menus 210, 240 in a preferred embodiment of the present invention are described in Table 1 illustrated in FIG. 4.
The menu of the present invention makes it easy to return to books, magazines, or newspapers last read. The present invention thus prevents periodicals, which tend to be read more frequently, from pushing books off of the ‘Recently Reading Now’ list.
FIG. 5 illustrates an exemplary local device 130. As appreciated by those skilled the art, the local device 130 can take many forms capable of operating the present invention.
