## Title
System and method for an electronic reader that allows access to additional content and tools

## Abstract

A method, system and non-transitory computer-readable medium are provided for controlling display of content on an electronic device with a touch screen display, which content may, in response to detection of a squeeze gesture, be reduced on the display screen to reveal additional content, tools and features associated with the one or more pages of the content.

## Background
FIELD OF THE INVENTION
The present invention generally relates to devices for reading digital content, and more particularly to systems and methods for improved navigation in an electronic publication.
BACKGROUND OF THE INVENTION
Electronic devices such as cellular phones, eReaders, and tablets are fast becoming necessities, especially for people on the move. Electronic devices can be used to place phone calls, to text messages, read electronic publications to browse the Internet, to take pictures and the like. The display area on a mobile electronic device can be limited due to its size, but the display area is usually adequate for viewing pictures or displaying text. Electronic devices typically include means for scrolling through text, such as pressing keys located on the device's keypad, a tracking wheel or other buttons located on the device.
The increasing popularity of touch screen devices with multitouch capabilities have alleviated, to some extent, the difficulties in navigating through digital publications. However the screen size of these mobile devices and the formatting of the electronic publications still presents a limitation on the ease with which one can navigate a digital publication. Improved systems and methods for navigating electronic documents using an electronic device would be desirable.
SUMMARY OF THE INVENTION
The present invention relates the user interface (UI) of an electronic reader. The invention allows the user to perform a multiple finger “squeeze” on the page of an electronic publication, thus shrinking its physical size on the screen. The reduced size page of the electronic publication reveals additional content or tools associated with the page or the electronic publication,



BRIEF DESCRIPTION OF THE DRAWINGS
For the purposes of illustrating the present invention, there is shown in the drawings a form which is presently preferred, it being understood, however, that the invention is not limited to the precise form shown by the drawings in which like reference characters refer to like parts throughout, and in which:
FIG. 1 illustrates an exemplary page in an electronic document as a user is performing a “squeeze” gesture on the page;
FIG. 2 illustrates an exemplary reduced size page, revealing additional content and functions associated with the page or the electronic publication; and
FIG. 3 illustrates a user selecting a note that was previously associated with the page or the electronic publication;
FIG. 4 illustrates an exemplary system according to the present invention; and
FIG. 5 illustrates the components of an exemplary device,



DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 illustrates a user viewing a page 200 of an electronic book on her electronic device 130. As shown h FIG. 1, the page 200 basically fills the entire screen of the device 130, plus or minus space for a status bar or some tool icons. User interfaces of electronic readers 130 are typically constructed this way to provide the maximum amount of text on the screen and to give the user the impression that she is reading a physical book.
As used herein, a “user” may be a single user or a group of users. As used herein, the term “user” (or “user device”, “client device”, “network-connected device” or “device”) can refer to any electronic apparatus configured for receiving control input and configured to send commands or data either interactively or automatically to other devices. As used herein, the term “method” refers to one or more steps performed at least by one electronic or computer-based apparatus. Steps may be performed in any order without departing from the scope of the invention.
FIG. 1 further illustrates the user touching three (or four or five) fingers on the screen of the device 130 that is displaying the page 200 and performing a squeezing gesture, like crumpling a piece of paper. The device 130 detects this gesture and interprets it as a command to reduce the size of the displayed page 200 and reveal the additional content and tools. Likewise, the user may perform an unsqueeze gesture. The device 130 detects this unsqueeze gesture and interprets it as a command to enlarge the size of the displayed page 200 and hide the additional content and tools
Alternative embodiments can support a two-finger squeeze gesture in contexts where a two-finger pinch gesture is not already devoted to another function such as zooming
Certain applications use two-finger pinch for zooming in and out, so a preferred embodiment uses three-or-more-finger-squeeze for the “reveal more information” gestures of the present invention. However designers may choose to allow two finger squeeze.
As shown in FIG. 2, in response to the user's squeezing gesture on the touch screen, the system shrinks the page 200 of the electronic publication on all sides (insetting) and thereby reveal additional content or tools 220, 230, 240 associated with the page 200 or the electronic publication. These could be tools or panels for doing things such as adding a note, marking a page with a “sticky” note 240, sharing the book or a quote within the page 200, starting, joining or reading discussions related to this book or related to the current page 200.
As appreciated by those skilled in the art, the types of features, tools, content applications revealed by the squeeze gesture of the present invention is only limited by the functions available on the reader 130. The discussion and sticky note features described above are merely exemplary. While the present disclosure discusses a few specific features, such as sticky notes 240, the squeeze gesture of the present invention can clearly reveal a wide variety of alternative features in addition to the ones described herein.
Pages 200 preferably remain active when displayed in a shrunken state. The user can flip them and read the next pages, for example. Some reading tools may be disabled while the page 200 is in its shrunken state.
FIG. 3 illustrates a user selecting a specific sticky note 260 that was previously applied on a page 250 of the electronic publication. As the user taps on the sticky note 260, the system turns the pages of the electronic publication until the specific page 250 on which the sticky note 260 was applied is revealed.
FIG. 4 shows components of a system according to the present invention. User 105 is an authorized user of system 100 and uses her local device 130a for the reading of digital content and interacting with other users, such as user 109. Many of the functions of system 100 of the present invention are carried out on server 150. As appreciated by those skilled in the art, many of the functions described herein can be divided between the server 150 and the user's local devices 130a, 130b. Further, as also appreciated by those skilled in the art, server 150 can be considered a “cloud” with respect to the users and their local devices 130a, 130b. The cloud 150 can actually be comprised of several servers performing interconnected and distributed functions. For the sake of simplicity in the present discussion, only a single server 150 will be described. The user 105 can connect to the server 150 via the Internet 140, a telephone network 145 (e.g., wirelessly through a cellphone network) or other suitable electronic communication means. User 105 has an account on server 150, which authorizes user 105 to use system 100.
Associated with the user's 105 account is the user's 105 digital locker 120a located on the server 150. As further described below, in the preferred embodiment of the present invention, digital locker 120a contains links to copies of digital content 125 previously purchased (or otherwise legally acquired) by user 105.
Indicia of rights to all copies of digital content 125 owned by user 105, including digital content 125, is stored by reference in digital locker 120a. Digital locker 120a 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 are not necessarily stored in the user's locker 120a, but rather the locker 120a 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, 109 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 lending server 150 can contain millions of files 125 containing digital content. It is also contemplated that the 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.
Also contained in the user's digital locker 120a is her contacts list. In a preferred embodiment, the user's contact list will also indicate if the contact is also an authorized (registered) user of the system 100 with his or her own account on server 150. This information can be used by some of the additional tools revealed when a page is in a shrunken state as described above.
User 105 can access his or her digital locker 120a using a local device 130a. Local device 130a is an electronic device such as a personal computer, an e-book reader, a smart phone or other electronic device that the user 105 can use to access the server 150. In a preferred embodiment, the local device has been previously associated or registered, with the user's 105 account using user's 105 account credentials. Local device 130a provides the capability for user 105 to download user's 105 copy of digital content 125 via his or her digital locker 120a. After digital content 125 is downloaded to local device 130a, 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 130a includes a non-browser based device interface that allows user 105 to initiate the discussion functionality of elements 220, 230 (FIG. 2), in a non-browser environment. Through the device interface, the user 105 is automatically connected to the server 150 in a non-browser based environment. This connection to the server 150 is a secure interface and can he through the telephone network 145, typically a cellular network for mobile devices. If user 105 is accessing his or her digital locker 120a using the Internet 140, local device 130a also includes a web account interface. Web account interface provides user 105 with browser-based access to his or her account and digital locker 120a over the Internet 140.
User 109 is also an authorized user of system 100. As with user 105, user 109 has an account with lending server 150, which authorizes user 109 to use lending system 100. As appreciated by those skilled in the art, the number of users 105, 109 that employ the present invention at the same time is only limited by the scalability of server 150. As with user 105, user 109 can access his or her digital locker 120b using her local device 130b. In a preferred embodiment, local device 130b is a device that user 109 has previously associated, registered, with his or her account using user's 109 account credentials. Local device 130b allows user 109 to download copies of his digital content 125 from digital locker 1 Mb. User 109 can engage with downloaded digital content 125 locally on local device 130b.
