Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] The present application is a continuation of U.S. patent
application Ser. No. 14/871,924 filed Sep. 30, 2015, which claims
the benefit of and priority to U.S. Provisional Application No.
62/146,219 entitled "COLUMN FIT DOCUMENT TRAVERSAL FOR READER
APPLICATION", filed on Apr. 10, 2015. Each of these references is
hereby incorporated by reference in its entirety for all
purposes.
BACKGROUND
[0002] The present disclosure relates generally to traversing a
document displayed in a graphical user interface of an application
such as a reader application. In particular, the disclosure relates
to presentation of a document that includes multiple columns of
text.
[0003] Documents can appear in various formats, such as a fixed
format. In a fixed format, text and images are laid out according
to, for example, columns. Examples of fixed format documents can
include textbooks, newspapers, magazine articles, etc. Use of fixed
format documents allows non-text content such as images to be
presented at a fixed position relative to relevant text. Multiple
articles may be arranged on a page in a visually appealing manner.
These and other aspects of fixed format documents may improve the
visual appearance and readability of document content. For example,
a fixed format document can more closely resemble the arrangement
and appearance of text and images from a textbook.
[0004] When a document including multiple columns is displayed on a
device having a small display size relative to the medium for which
a document was originally formatted, the content of columns may be
smaller than is desirable for some users. Users may benefit from a
presentation of multi-column documents that improves legibility.
Further, when a fixed format document is displayed on a device,
users may benefit from a method of viewing content in a consistent
manner.
BRIEF SUMMARY
[0005] In accordance with exemplary embodiments, a method is
described. The method includes displaying, with a display of an
electronic device, a view of a lower portion of a first column from
a document. The document includes at least a first column and a
second column. A first user input gesture is received by the
electronic device. In response to detecting the first user input
gesture, the display of the electronic device displays an animated
transition from the view of the lower portion of the first column
to a view of an upper portion of the second column.

DETAILED DESCRIPTION
[0023] In accordance with various exemplary embodiments, a
technique is described for displaying a document with content
presented in multiple columns, such as a fixed-format document. The
columns of the document may be presented using a desirable column
size, e.g., for legibility of the content. A zoom level of the
content can be adjusted according to the column size.
[0024] An "electronic device" as described herein may be any
computing device capable of displaying an image, such as a portable
electronic device (e.g., mobile phone, media player, tablet,
wearable device, laptop, personal digital assistant, gaming device,
etc.), desktop electronic device, or other computing device. The
electronic device may include a touch-sensitive surface, such as a
touchscreen and/or touchpad. The electronic device may display an
image using an integrated display component, e.g., by rendering the
image on the display. In some exemplary embodiments, an electronic
device may display an image by transmitting the image to a remote
device (e.g., a monitor, navigation unit, or other remote device
communicatively connected to the electronic device). The electronic
device may be capable of executing one or more applications.
Applications executed by a device may include, for example, a
document reader, an Internet browser, a word processing
application, or other application capable of displaying a
document.
[0025] A "document" as described herein may be an electronic book,
a document formatted for portability, a file produced and/or used
by a word processing application, a website, a webpage, or any
other document. An electronic book can include, for example, a
multi-touch book or an author book. A multi-touch book or an author
book is an interactive electronic document. A document may include
one or more pages. For example, an electronic book may include a
series of pages. In another example, a website may include a set of
one or more interlinked pages (i.e., webpages, such as webpages
defined by an HTML document.) A page may include multiple
columns.
[0026] A "column" as described herein may include content such as
text, images, video, and/or other content. The content of a column
may be arranged in a block configuration. A column may
substantially or fully span the vertical extent of a page and
partially span the horizontal extent of a page. For example, a page
with two columns may include a column located on the left half of
the page and another column located on the right half of the page.
A whitespace area (i.e. "gutter"), such as a vertical stripe of
whitespace, may be located between two columns on a page. As
described further below, a page may be partially displayed such
that a single column or part of a single column is visible within
the area of the display.
[0027] A "gesture" as described herein may include an input that
corresponds to a pattern stored and recognized by an electronic
device. An electronic device may store one or more responses in
association with a gesture. In response to receiving a gesture, the
electronic device may perform one or more of the responses
associated with the gesture. The response associated with the
gesture may vary, for example, between a portrait mode and a
landscape mode of the electronic device. An input may be, for
example, a contact received at a touch-sensitive surface such as a
touchpad or touchscreen. In some exemplary embodiments, a gesture
input may be provided with a finger, multiple fingers, a thumb, a
combination of a finger and a thumb, a mouse or other input
device.
[0028] Gestures may include, e.g., a linear swipe, a diagonal
swipe, a pan, a flick, a tap, a double tap, a tap and hold, a pinch
and a stretch. A linear swipe is a motion from a first point to a
second point on a display, such as a swipe of a finger along a
touch-sensitive surface from a starting contact point to an ending
contact point. A diagonal swipe is similar to a linear swipe but
the motion is made at a diagonal on the display. For example, from
a right top corner of a display to a bottom left corner of the
display. A pan can be similar to a swipe but contact on the display
can be maintained for a longer period of time. For example, a user
can maintain contact on the display while moving their finger on
the content. A flick is a quick swiping motion. A flick is input at
a higher rate of motion than a swipe. A flick can be made upward
(upward flick) or downward (downward flick).
[0029] A tap can include touching or tapping the display a single
time. A double tap can include touching or tapping the display two
times. A tap and hold can include touching a point on the display
and maintaining the hold for a predetermined amount of time. A
pinch can include making a pinching motion using, for example, a
thumb and forefinger on the display. A stretch can include, for
example, separating the thumb and forefinger on the display. A
result of the gesture can vary according to, for example, a type of
the document and a layout of the document. Various types of
gestures can be used and the above gestures are merely
examples.
[0030] "Zoom" as indicated herein may refer to digitally altering
the size of document content. For example, when zoom is increased,
the magnification level of a displayed document may be increased.
Increasing the zoom level may reduce the area of a document visible
in a portion of a display in which the document is displayed.
Similarly, when zoom is decreased, the magnification level of the
displayed document may be decreased.
[0031] Content from a document can be displayed in different modes.
For example, content can be displayed in a full-page mode or a
guided-pan mode. In a full-page mode or whole-page mode, a
full-page of the document will appear on the display. As a user
pans through the document, a full-page will appear on the display
at a given time. In a guided-pan mode, a part of a page of the
document, such as a column, will appear on the display. As a user
pans through the document, a part of a page of the document will
appear on the display. In a guided-pan mode, content can be
displayed according to a column fit mode.
[0032] In a column fit mode, text can remain in columns as
formatted by an author of the document. For example, in a textbook,
columns can have different widths, spacing, and indentations
according to the content being described and the images which are
included on the page. When a user views a document in a guided-pan
mode, the content will remain in a column fit mode. That is, the
content will remain in column formatting. If there is more text in
a particular column, the text of the column being viewed may be
smaller. If there is less text in a particular column, the text of
the column being viewed may appear larger. The text is displayed
according to, for example, the amount and type of content which
appears in the column of a document and the size and shape of the
display area of the electronic device. Therefore, in a column fit
mode, the content can be appropriated to fit in a column.
[0033] FIG. 1 shows an illustrative electronic device 100
displaying a page 104, according to an exemplary embodiment. The
content displayed in FIG. 1 can be according to a full-page mode.
Electronic device 100 includes display 102. Page 104 including
multiple columns 106, 108 is displayed by electronic device 100 at
display 102. Page 104 may be a page from among a series of pages of
a document, such as an electronic book.
[0034] In the full-page mode, if a user swipes from left to right
on page 104, and there is a previous page in the document, a full
previous page can be displayed. If a user swipes from right to left
on page 104, and there is subsequent page in the document, a full
subsequent page can be displayed.
[0035] Displaying the entirety of page 104 on display 102 may be
desirable in various situations, such as when a user wishes to see
all content available on a page, to provide context for a column
within a document or a page of a document during traversal of the
document, etc. When display 102 is displaying the entirety of page
104, including left column 106 and right column 108, the content of
columns 106, 108 may be smaller than is desirable for some readers.
For example, legibility of text and images within columns 106, 108
may be limited by the size of the displayed content on the display
102.
[0036] FIGS. 2A and 2B show an illustrative electronic device 100
displaying content from a single column 106 of page 104 and from a
single column 108 of page 4, respectively. The content displayed in
FIGS. 2A and 2B can be according to a guided-pan mode which
incorporates a column fit mode. In FIG. 2A, the legibility of the
text of column 106 may be improved for some readers because of the
increased size of the content (e.g., the text of column 106) when a
single column is displayed within the area of display 102.
[0037] In some exemplary embodiments, a transition from the whole
page view of page 104 as displayed in FIG. 1 to the single column
view of page 104 as displayed in FIG. 2A may occur in response to
user input received by electronic device 100. Electronic device 100
may receive input via a touch-sensitive surface. For example,
display 102 may be a touchscreen display. A transition from the
whole page view of page 104 as displayed in FIG. 1 to the single
column view of page 104 as displayed in FIGS. 2A and 2B may occur
in response to, e.g., a "double tap" input, such as a brief contact
of a finger with a portion of a touchscreen display two times. For
example, when a user double taps display 102 at a portion of
display 102 in which column 106 is shown, a transition may occur to
display a column 106 as a single column within the area of display
102. A double tap is described, however, this is merely an example.
If a user were to tap only once, a toolbar for the application can
be invoked.
[0038] Different types of inputs may be used to transition from
display of page 104 at a first zoom level (e.g., as indicated at
FIG. 1) to a second zoom level (e.g., as indicated at FIGS. 2A and
2B) and/or to transition from a second zoom level to a first zoom
level. In various exemplary embodiments, electronic device 100 may
perform the transition from a whole page view to a single column
view in response to another type of input.
[0039] Electronic device 100 may determine a location of the
display 102 at which an input is received. If the input was
received at a location of the whole page view of FIG. 1 where
column 106 is shown, electronic device 100 may display column 106
in a single column view as indicated in FIG. 2A. If the input was
received at a location of the whole page view of FIG. 1 where
column 108 is shown, electronic device may display column 108 in a
single column view as indicated in FIG. 2B. Electronic device 100
may determine a column position displayed at a location of display
102 at which the input was received. For example, if the input was
received at a position within an upper portion of column 106
displayed in the whole page view, electronic device 100 may display
the upper portion of column 106 in a single column view. If the
input was received at a position within a lower portion of column
106 displayed in the whole page view, electronic device 100 may
display the lower portion of column 106 in a single column
view.
[0040] Although electronic device 100 is shown with display 102
displaying a single column (e.g., column 106) in "portrait" mode in
FIGS. 2A and 2B, a single column may similarly be shown in
"landscape" mode. For example, if at any time the electronic device
100 is rotated by the user (e.g., rotated by 90 degrees relative to
the orientation shown at FIGS. 2A and 2B), a single column 106 may
be displayed in landscape mode such that the single column is
displayed within the area of display 102 in landscape mode.
Gestures on the display can provide different results according to
whether the electronic device 100 is in a portrait mode or a
landscape mode. Further, the amount of content that is displayed on
the display can vary according to portrait mode or landscape
mode.
[0041] In FIG. 2A, the upper portion of column 106 from page 104 is
displayed at display 102. Electronic device 100 may receive user
input to change the content from page 104 displayed by display 102.
For example, electronic device 100 may receive user input to
display content from a lower portion of column 106 than the portion
of column 106 that is currently displayed at display 102.
[0042] FIGS. 3A and 3B illustrate a transition from displaying an
upper portion of column 106 to a lower portion of column 106,
according to an exemplary embodiment. At FIG. 3A, an upper portion
of the content of column 106 is displayed by display 102. At FIG.
3B, a lower portion of the content of column 106 is displayed by
display 102. In some exemplary embodiments, a column may include
one or more portions, such as an upper portion (e.g., the "top" of
the column), one or more central portions, and a lower portion
(e.g., the "bottom" of the column). A lower portion may refer to
any portion of a column that is lower than the currently displayed
portion of the column, and an upper portion may refer to any
portion of a column that is above the currently displayed portion
of the column.
[0043] Electronic device 100 may transition from displaying an
upper portion of column 106 to a lower portion of column 106 in
response to user input received at electronic device 100.
Electronic device 100 may use an animation to indicate the
transition as (and/or after) the input gesture is received. For
example, the text of column 106 may be animated such that the text
appears to gradually roll upward as the input gesture is received.
Further, a zoom level of the text of column 106 can change as the
input gesture is received.
[0044] Electronic device 100 may perform the transition illustrated
in FIGS. 3A and 3B in response to a gesture input received at a
touch-sensitive surface of electronic device 100. For example, the
gesture input may be an input 300 that occurs when user "swipes
upward" by dragging a finger along display 102 from a lower contact
position indicated by circle 302 of FIG. 3A to an upper contact
position indicated by circle 304 of FIG. 3A. In response to the
upward swipe, electronic device 100 may display a lower portion of
the content of column 106, as indicated at FIG. 3B. The transition
from the display of the upper portion of the content of column 106
as indicated at FIG. 3A to the display of the lower portion of the
content of column 106, as indicated at FIG. 3B may be presented as
a gradual animated transition as (and/or after) the upward swipe
occurs.
[0045] If a user uses a pan gesture, that is, the user maintain
contact with display 102 while panning from, for example, the
bottom of column 106 toward the top of column 106, the animation
can appear as a change in zoom level. The zoom level of the text
can decrease and additional content of page 104 can be displayed on
the display 102, thereby giving a user additional context. When the
user stops panning at a particular location on column 106, the text
can return to its original display size for column 106.
[0046] It will be recognized that, where an upward swipe, pan, and
other particular gestures are described herein, alternative
gestures and other inputs may be used to adjust the content
displayed by display 102, including an upward flick, a downward
swipe or flick, a horizontal swipe (e.g., right-to-left swipe or
left-to-right swipe) or flick, a diagonal swipe or flick, a tapping
input, an input provided with two or more fingers (such as a
pinching gesture), etc. A flick may be a gesture input provided at
a higher rate of motion than a swipe. Different input types may be
used by electronic device 100 to determine whether a transition in
zoom level is to occur as the column content of page 104 displayed
by the electronic device change.
[0047] FIGS. 4A-4B illustrate a transition from displaying a lower
portion of column 106 to displaying an upper portion of column 108,
according to an exemplary embodiment. At FIG. 4A, a lower portion
of the content of column 106 is displayed by display 102. At FIG.
4B, an upper portion of the content of column 108 is displayed by
display 102.
[0048] Electronic device 100 may transition from displaying a lower
portion of column 106 to displaying an upper portion of column 108
in response to user input received at electronic device 100.
Electronic device 100 may use an animation to indicate the
transition as (and/or after) the input gesture is received. For
example, page 104 may be animated such that it appears to slide
diagonally to the lower right as the input gesture is received.
Further, page 104 may be animated by changing a zoom level of page
104.
[0049] In some exemplary embodiments, electronic device 100 may
perform the transition illustrated in FIGS. 4A and 4B in response
to a gesture input received at a touch-sensitive surface of
electronic device 100. For example, the gesture input may be an
input 400 that occurs when a user swipes from right to left by
dragging a finger along display 102 from a lower right contact
position indicated by circle 402 of FIG. 4A to a lower left contact
position indicated by circle 404 of FIG. 4A. In response to the
right-to-left swipe, electronic device displays a upper portion of
the content of column 108, as indicated at FIG. 4B. The transition
from the display of the lower portion of the content of column 106
as indicated at FIG. 4A to the display of the upper portion of the
content of column 108, as indicated at FIG. 4B may be presented as
a gradual animated transition as the right-to-left swipe
occurs.
[0050] In the guided-pan mode, if the user is at a bottom of a
column, when the user swipes from right to left, the top of the
subsequent column appears. If the user it at the top of a column
and swipes from left to right, the bottom of the previous column
appears. Therefore, a reading order is followed.
[0051] It will be recognized that the transitions described herein,
such as the transition described with regard to FIGS. 4A and 4B,
may be used for a transition from a column of a current page to a
column of a subsequent page, a transition from a current page to a
subsequent page, a transition from a current column to a previous
column, a transition from a current page to a previous page, etc.
Different input types or different directions of gesture input may
be used by electronic device 100 in order to determine the
appropriate destination (e.g., subsequent column, subsequent page,
previous column, previous page, etc.) of a transition.
[0052] As illustrated in FIGS. 3A-3B, a user reading page 104
displayed by electronic device 100 can swipe continuously upward to
advance through column 106. When the end of column 106 is reached,
the user may swipe from right to left to advance from a lower
portion of column 106 to an upper portion of column 108. In this
way, columns 106, 108 of page 104 are navigable in an intuitive and
user-friendly manner.
[0053] If a user continues to swipe upward on a column and they
have reached the end of a column, a user can be notified that they
have reached the end of a column through an animation. For example,
a zoom level of the text in the bottom of column 106 may decrease,
that is the size of the text may decrease, and then revert back to
the original size of the text in the bottom of the column 106.
Therefore, the text may change in size and then snap back to their
original display size. No additional text appears and the user is
"locked" to the column. Therefore, the user is informed that they
are at the end of a column.
[0054] FIGS. 5A, 5B and 5C illustrate a transition from displaying
content in a guided-pan mode to a full-page mode, according to an
exemplary embodiment.
[0055] As shown in FIG. 5A, the content 504 is displayed in
guided-pan mode. A drag, swipe, or a pinch that results in
displaying a large portion of the page can be used to exit the
guided-pan mode and enter the full-page mode. For example, an input
500 that results in displaying a large portion of the page can
include touching a first point as indicated by circle 501 on an
upper left corner of the display and maintaining contact with the
display toward a lower right point of the display indicated by
circle 502, as shown in FIG. 5A.
[0056] As the contact moves from, for example, a contact point
indicated at circle 501 to a contact point indicated at circle 502,
as shown in FIG. 5B the amount of content 505 displayed on the
display can increase. If the user releases contact with the display
at the contact point indicated at circle 502 and a majority of the
page is displayed at that time, as shown in FIG. 5C, the document
can enter the full-page mode and the full-page 506 is
displayed.
[0057] However, if, for example, the user releases contact with the
display at a point prior to the contact point indicated at circle
502, the content can continue to be displayed in a guided-pan mode.
That is, the user may decide that they do not want to switch to the
full-page mode or the user wanted to see more content on the page
but did not want to exit the guided-pan mode. Therefore, the user
can release contact with the display at a point between circle 501
and circle 502 to remain in a guided-pan mode.
[0058] Since the contact on the display from the contact pointed
indicated at circle 501 to the contact point indicated at circle
502 extends along a large area of the display, the zoom level can
be decreased, that is, the size of the text is decreased, thereby
displaying more content on the display. Since content of the whole
page or a majority of the page is displayed at the time contact
with the display is released, the whole page is displayed. A top to
bottom drag is described with respect to FIGS. 5A, 5B, and 5B,
however, this is merely an example. The gesture can include, for
example, a motion from bottom to top.
[0059] FIG. 6 illustrates an electronic device 100 displaying a
table of contents view 600 of a document, according to an exemplary
embodiment.
[0060] If the user is in the full-page mode, as shown in FIG. 1,
and the user, for example, swipes downward (from top to bottom) or
pinches the display, the user can exit the full-page mode and can
enter a table of contents view 600 of the document, as shown in
FIG. 6. The table of contents view 600 can show the table of
contents 601 of, for example, content in a particular chapter of a
textbook and can include cover images. Additionally, the table of
contents view can include thumbnail views of pages of the chapter,
such as pages 602 and 603 of the chapter.
[0061] Two pages are shown in FIG. 6, however, one or more pages
can be shown. A user can scroll through the different chapters in
the book using for example, buttons 604. For example, each of the
buttons 604 can correspond to a different chapter. A top to bottom
swipe is described with respect to FIG. 6, however, this is merely
an example. The gesture can include, for example, a motion from
bottom to top to enter the table of contents view 600. Further, in
the table of contents view 600, if the user swipes from top to
bottom, the book can be exited.
[0062] FIG. 7 is a flow diagram indicating exemplary operations of
a method 700 for transition within a document from displaying a
current column of the document to displaying another column of the
document, according to an exemplary embodiment.
[0063] At operation 701, electronic device 100 may determine a
current column and/or a current column position. For example, if a
document is being accessed for the first time on electronic device
100, a current column may be a first column (e.g., column 106) from
a first page (e.g., page 104) of the document and a current column
position may be, e.g., an upper portion of the first column. When
the document is accessed on subsequent occasions, electronic device
100 may determine the current column and current column position to
be a most recently visited column and column position of the
document. A user may move forward and backward in the document to
access columns preceding and/or following the currently displayed
column.
[0064] At operation 702, electronic device 100 may display, by
display 102, the determined current column (e.g., column 106) at
the determined column position (e.g., an upper portion of column
106). The current column may be displayed at a first zoom
level.
[0065] At decision diamond 704, electronic device 100 may determine
whether an input to change the currently displayed column content
is received. For example, electronic device 100 may determine
whether a column advancement input such as the upward swipe 300 as
illustrated in FIG. 3A or a right-to-left swipe 400 as shown in
FIG. 4A, has been received. If no input to change the currently
displayed column content has been received, flow may return to
operation 704. In alternative exemplary embodiments, if no input to
change currently displayed column content has been received, flow
may proceed to decision diamond 900, as indicated by optional
operation A. If input to change currently displayed column content
has been received, flow may proceed to operation 706.
[0066] At decision diamond 706, electronic device 100 may determine
whether the end of the current column is currently displayed (e.g.,
if the input is input to move forward within a document).
Alternatively, if the received input is input to move backward
through a document, decision diamond 706 may determine whether the
beginning of the current column is currently displayed. For
example, electronic device 100 may determine whether the end of
column 106 is currently displayed by display 102. If the end (for
forward movement through the document) or beginning (for backward
movement through the document) of the current column is not
currently displayed, flow may proceed to operation 708. If the end
(for forward movement through the document) or beginning (for
backward movement through the document) of the current column is
not currently displayed, flow may proceed to operation 710.
[0067] At operation 708, electronic device 100 may change the
position of column content based on the received input (e.g., as
determined at decision diamond 704). For example, for forward
movement thought the document, the advancement of the column
content may be a transition from displaying an upper portion of a
column (e.g., an upper portion of column 106, as illustrated at
FIG. 3A) to displaying a lower portion of the column (e.g., a lower
portion of column 106, as illustrated at FIG. 3B). The transition
may be indicated with an animation, e.g., as discussed with regard
to FIGS. 3A-3B.
[0068] At operation 710, electronic device 100 may transition from
displaying a portion of a first column to displaying a portion of
another column. For example, for forward movement through the
document, electronic device 100 may transition from displaying a
lower portion of a current column (e.g., a lower portion of column
106, as illustrated at FIG. 4A) to displaying an upper portion of a
subsequent column (e.g., an upper portion of column 108, as
illustrated at FIG. 4B). The transition may be indicated with an
animation, e.g., as discussed with regard to FIGS. 4A-4B.
[0069] In some exemplary embodiments, contextual information is
provided during a transition between a current column and a
subsequent column (e.g., columns 106, 108). For example, as the
transition from a lower portion of a current column to an upper
portion of a subsequent column occurs, page 104 may be shown at a
first zoom level when the lower portion of the current column is
displayed, at a second zoom level during the transition, and at the
first zoom level when the upper portion of the subsequent column is
displayed. The animated transitions from the first zoom level to
the second zoom level and from the second zoom level to the first
zoom level may be gradual transitions. The second zoom level may be
a lower level of zoom (i.e., more content from page 104 is shown)
than the first zoom level. In this way, a user is provided with
information about the content of page 104 for the period of time
during which the transition from a current column to a subsequent
column occurs. The gradual transitions between zoom levels allow
for a smooth and visually appealing indication of the progress of
the transition. In some exemplary embodiments, the animated
transition from the first zoom level to the second zoom level
occurs at a slower rate than the animated transition from the
second zoom level to the first zoom level.
[0070] A first type of transition may occur when input described
with regard to FIGS. 3A-3B and 4A-4B is received and a second type
of transition may occur when a different type of input is received.
For example, the first type of transition may involve no change in
zoom level, whereas the second type of transition may involve a
change from a first zoom level to a second zoom level as described
above. In another example, the first type of transition may involve
a change from a first zoom level to a second zoom level as
described above and the second type of transition may involve a
change from a first zoom level to a third zoom level. The third
zoom level may be a lower level of zoom than either the first zoom
level or the second zoom level. In various exemplary embodiments, a
second and/or third zoom level of page 104 as described above may
allow two or more columns (e.g., columns 106, 108) to be viewed
simultaneously during the transition.
[0071] FIGS. 8A, 8B, and 8C illustrate a transition from a current
column 106 of page 104 to a subsequent column 108 of page 104
including display of page 104 at various zoom levels during the
transition.
[0072] At FIG. 8A, a lower portion of the content of column 106 is
displayed by display 102 at a first zoom level in which a single
column view of column 106 is displayed. At the first zoom level,
the width of column 106 may be equal or substantially equivalent to
the width of display 102. At FIG. 8B, page 104 is displayed by
display 102 at a second zoom level in which part or all of both
column 106 and column 108 are visible within display 102. The
second zoom level may be an intermediate zoom level in which column
106 and/or column 108 are partially visible within the display. The
second zoom level may alternatively be a whole page zoom level in
which column 106 and column 108 are wholly visible within display
102. At FIG. 8C, an upper portion of the content of column 108 is
displayed by display 102 at the first zoom level. In FIG. 8C, a
single column view of column 108 is displayed. The width of column
108 may be equal or substantially equivalent to the width of
display 102.
[0073] The change in zoom levels can assist a user in navigating
through columns of a document in a pan-guide mode. For example,
decreasing the zoom level as the user pans through a document can
assist a user in determining associated content on the page or
content in a next or previous column. Further, the speed of the
animation or changes in the zoom level can vary according to the
speed of the gesture. For example, a flick can result in a faster
animation while swipe can result in a slower animation.
[0074] Electronic device 100 may transition from displaying a lower
portion of column 106 to an upper portion of column 108 in response
to user input received at electronic device 100. Electronic device
100 may use an animation to indicate the transition as (and/or
after) the input gesture is received. For example, page 104 may be
animated such that it appears to slide diagonally to the lower left
as the transition from the content displayed in FIG. 8A to the
content displayed in FIG. 8B occurs. Page 104 may be animated such
that it appears to zoom in quickly (i.e., "snap") from displaying
page 104 at the second zoom level to displaying the top of column
108 at the first zoom level, i.e., the rate of the transition from
FIG. 8B to FIG. 8C may be greater than the rate of the transition
from FIG. 8A to FIG. 8B.
[0075] The transition from the display of the lower portion of the
content of column 106 as indicated at FIG. 8A to the display of the
upper portion of the content of column 108, as indicated at FIG. 8C
may be presented as a gradual animated transition as (and/or after)
input 800 occurs. For example, the animated transition may follow a
"Z-shape" (e.g., in which the page slides to the left, subsequently
slides diagonally or vertically downward, and subsequently slides
to the right), an "S-shape," a diagonal line, reverse Z-shape
(e.g., for moving to the prior column), reverse S-shape, or another
transition pattern. It will be recognized that other directions,
types, and rates of animation may be used to illustrate the
transition from FIG. 8A to FIG. 8B and the transition from FIG. 8B
to FIG. 8C. For example, the shape of the movement can vary
according to the location of the text on a next column or if an
image appears before text on a on next column.
[0076] Electronic device 100 may perform the transition illustrated
in FIGS. 8A-8C in response to a gesture input received at a
touch-sensitive surface of electronic device 100. For example, the
gesture input may be an input 800 that occurs when user swipes or
flicks diagonally by dragging a finger along display 102, e.g.,
from an upper right contact position indicated by circle 802 of
FIG. 8A to a lower left contact position indicated by circle 804 of
FIG. 8A. It will be recognized that alternative gestures as
described herein may be used as input 800. In response to received
input 800, electronic device may display a transition to a portion
of page 104 including column 106 and column 108, as shown in FIG.
8B, and a further transition to a portion of the content of column
108, as indicated at FIG. 8C.
[0077] The transitions described with regard to FIGS. 8A-8C may be
used for transitioning from a column of a current page to a column
of a subsequent page or a column of a previous page. For example,
after the transition from the column view shown in FIG. 8A to the
zoomed out page view shown in FIG. 8B has occurred, electronic
device 100 may receive continued or further user input (e.g., a
horizontal dragging motion or drag-and-hold motion) to advance to a
subsequent page following page 104 shown in FIG. 8B. A user may
continue to provide input to view a series of pages, as described
further below with regard to FIGS. 10, 11 and 12.
[0078] FIG. 9 is a flow diagram indicating exemplary operations of
a method 900 for movement within a document from displaying a first
column to displaying another column, according to an exemplary
embodiment.
[0079] At decision diamond 901, electronic device 100 may determine
whether an input to move to a different column is received. The
input may be an input to advance to a subsequent column or an input
to view a prior column of the document. For example, electronic
device 100 may determine whether an input such as the diagonal
swipe 800 as illustrated in FIG. 8A has been received. If no input
to move to a different column has been received, flow may return to
decision diamond 704, as indicated at operation B. If an input to
move to a different column has been received, flow may proceed to
operation 902.
[0080] At operation 902, electronic device 100 may transition from
displaying a portion of a first column to a portion of another
column of a document.
[0081] For example, if the input is an input to advance to a
subsequent column, the transition may be a transition from
displaying a lower portion of a first column (e.g., a lower portion
of column 106, as illustrated at FIG. 8A) at a first zoom level to
displaying page 104 at a second zoom level, e.g., as illustrated at
FIG. 8B. The second zoom level may be a lower level than the first
zoom level, such that a larger portion of page 104 is visible
within display 102. For example, part or all of columns 106 and 108
may be visible within display 102 when page 104 is displayed at the
second zoom level.
[0082] At operation 904, electronic device 100 may transition from
displaying a page at the second zoom level (e.g., as illustrated at
FIG. 8B) to displaying another column at the first zoom level. For
example, electronic device 100 may transition from displaying page
104 at a second zoom level to displaying an upper portion of a
subsequent column (e.g., an upper portion of column 108, as
illustrated at FIG. 8C). The transition may be indicated with an
animation, e.g., as discussed with regard to FIGS. 8A-8C.
[0083] In various exemplary embodiments, operation 902 may occur
before operation 904, operation 902 may occur after operation 904,
or operations 902 and 904 may occur simultaneously or substantially
simultaneously.
[0084] In some exemplary embodiments, a drag gesture (e.g.,
horizontal swipe) may be used to traverse multiple columns or
multiple pages and, when the drag gesture is terminated with a hold
gesture, a column displayed when the hold gesture is received may
be displayed. A hold gesture may be, for example, a sustained
contact received at a single part of a display. When the drag
gesture is terminated with a liftoff gesture, a page displayed when
the liftoff gesture is received may be displayed. A liftoff may be
a removal of the contacting element (e.g., finger) used for the
drag gesture or other gesture as the gesture is received.
[0085] FIG. 10 shows an illustrative electronic device 100
displaying a sequence of multiple columns 106, 108, 1024, 1026, as
shown at 1000, 1004, 1006, 1008, 1010 and 1012, respectively,
according to an exemplary embodiment. Electronic device 100 may
receive input for traversing multiple columns. The input may be,
for example, a continuous horizontal swipe (i.e. dragging motion)
as shown at 1002. Continuous horizontal swipe 1002 is additionally
shown as a series of component swipes 1014, 1016, 1018, 1020, and
1022 of continuous horizontal swipe 1002, as indicated at 1004,
1006, 1008, 1010, and 1012, respectively. A first time frame of
swipe 1002 is shown at 1014, a second time frame following the
first time frame of swipe 1002 is shown at 1016, and so on for
1018, 1020, 1022. In some exemplary embodiments, each time a page
boundary is traversed in response to received user input, the
subsequent page may be displayed at a whole page zoom level or
intermediate zoom level (e.g., as described with regard to FIG. 1
and FIG. 8B, respectively).
[0086] As input 1002 is received, a sequence of pages, such as a
first page 104 and a second page 1028, may be displayed. In some
exemplary embodiments, a page is shown at different zoom levels
each time a column of the page is traversed. For example, as page
104 is traversed, page 104 is shown at a first zoom level at 1004
such that column 106 is predominantly displayed, page 104 is shown
at a second zoom level at 1006 such that both columns are equally
displayed, and page 104 is shown at the first zoom level at 1008
such that column 108 is predominantly displayed. Similarly, as the
user continues providing input 1002 to traverse from page 104 to
page 1028, page 1028 is shown at the first zoom level at 1010 such
that column 1024 is predominantly displayed, page 1028 is shown at
a second zoom level at 1012 such that both columns of page 1028 are
equally displayed, and so on.
[0087] The amount of content of the column displayed at the first
zoom level and second zoom level described with regard to 1004-1012
may differ from the illustrative example of FIG. 10. For example,
at a first zoom level, a single column may be displayed. At a
second zoom level, part or all of two or more columns may be
displayed. If the device is in a landscape mode, additional content
can be seen on the display as compared with the portrait mode shown
in FIG. 10. For example, content from part of a previous page or
content from part of a subsequent page can also be displayed when
scrolling through pages of the document.
[0088] Where two columns are described as "equally displayed," it
will be understood that the columns may be substantially equally
displayed. For example, when a first column and a second column are
substantially equally displayed, a size of a first column may vary
from a size of a second column by no more than 25% (e.g., by no
more than 10%) of the total column width.
[0089] Where a column is described as "predominantly displayed,"
the predominantly displayed column may consume, for example, more
than 50% (e.g., by more than 70%) of the page.
[0090] Animated transitions as described herein may be used for the
transitions between 1004-1006, 1006-1008, 1008-1010, and
1010-1012.
[0091] Electronic device 100 may receive a user input indicating
that a predominantly displayed column is to be displayed in a
column fit view (e.g., as shown at FIG. 2). The input may be, for
example, a hold input received as a desired column is being
traversed to select the column. If a user wishes to select column
108, then user may interrupt input 1002 by providing a hold input
at the time that column 108 is predominantly displayed, as
indicated at 1008. This sequence of gestures may be referred to as
a "drag-hold" input. As a result, column 108 may be displayed in
column fit view (e.g., as shown at FIG. 8C).
[0092] FIGS. 11A, 11B and 11C show an illustrative electronic
device traversing a document having a page that does not include
body text, according to an exemplary embodiment.
[0093] As shown in FIG. 11A, if a user is in guided-pan mode, a
column 1101 is displayed in guided-pan mode. If the next page after
column 1101 does not include any columns, that is the next page
1102 does not include any body text and only includes, for example,
an image, then the image is displayed in a full-page mode as shown
in FIG. 11B. When the user continues to the next column after page
1102, the top of column 1103 after page 1102 is displayed. If a
page does not include text, and includes only, for example, an
image, then the image with an image is displayed as a whole page.
Therefore, the user can have a clearer and larger view of the
image. However, the user can continue to scroll through the
document in the guided-pan mode.
[0094] FIG. 12 is a flow diagram indicating exemplary operations of
a method 1200 for displaying a sequence of multiple columns,
according to an exemplary embodiment.
[0095] At operation 1202, electronic device 100 may display, by
display 102, a current column (e.g., column 106) at a current
column position (e.g., an upper portion of column 106). The current
column may be displayed at a first zoom level such that a single
column is displayed by display 102.
[0096] At decision diamond 1204, electronic device 100 may
determine whether an input to change from displaying a current
column to displaying another column is received. For example,
electronic device 100 may determine whether a horizontal drag input
has been received. If no input to change from displaying a current
column to displaying a next column has been received, flow may
return to operation 1204. If input to change from displaying a
current column to displaying a next column has been received, flow
may proceed to operation 1206.
[0097] At operation 1206, electronic device 100 may display a
transition from a current column to a next column in a direction
indicated by the received input. For example, if the input to
change from displaying a current column to displaying another
column is a left-to-right drag, e.g., as indicated at 1014-1018 of
drag 1002, a transition from a first column to a subsequent column
may be shown, e.g., a transition from column 106 to column 108 as
indicated at 1004-1008. In some exemplary embodiments, page 104 may
be shown at a first zoom level, as indicated at 1004, a second zoom
level, as indicated at 1006, and again at the first zoom level, as
indicated at 1008, as the left-to-right drag occurs.
[0098] In another example, an input to change from displaying a
current column to displaying another column may be a right-to-left
drag. In this example, a column prior to the currently displayed
column may be displayed at operation 1206.
[0099] At decision diamond 1208, electronic device 100 may
determine whether a liftoff input is received. A user may terminate
a drag input with a liftoff input when a column the user desires to
view is predominantly displayed. If a liftoff input is received,
flow may proceed to operation 1210.
[0100] At operation 1210, electronic device 100 may display the
column selected at the time of liftoff. For example, the column
selected at the time of liftoff may be a column predominantly
displayed when the liftoff input is received. The current column
may be displayed at the first zoom level such that a single column
is displayed by display 102 (e.g., as shown at FIG. 4B). For
example, if a liftoff input is received when column 108 is
predominantly displayed, as indicated at 1008, column 108 may be
displayed by display 102 (e.g., at the zoom level indicated in FIG.
4B) in response to the received liftoff input.
[0101] It will be recognized that alternative gestures or other
inputs as discussed herein may be used in lieu of the drag, hold,
and liftoff inputs discussed with regard to FIG. 12. Typically, the
first, second, and third zoom levels are different zoom levels,
although it will be recognized that some or all of these zoom
levels may be the same zoom level.
[0102] In various exemplary embodiments, the velocity of the
received input gesture may be used by electronic device 100 to
determine whether to traverse a document as indicated with regard
to FIGS. 8A-8C or to traverse the document as indicated with regard
to FIG. 10. For example, when a velocity at which a contact with a
touch-sensitive surface traverses the surface falls below a
threshold rate, the traversal as described with regard to FIGS.
8A-8C may be used. When a velocity at which a contact with a
touch-sensitive surface traverses the surface is above a threshold
rate, the traversal as described with regard to FIG. 10 may be
used. In some exemplary embodiments, a level of zoom with which a
document is displayed may vary in proportion to a velocity of a
received input gesture.
[0103] FIG. 13 shows an illustrative electronic device 100 that is
in landscape mode and is capable of displaying multiple pages 104,
1308, 1310, 1312 simultaneously, according to an exemplary
embodiment. As shown in table of contents view 1300, a region 1320
can display a table of contents for a particular chapter of a text
book. Pages 104, 1308, 1310, 1312 can correspond to pages in the
chapter. FIG. 13 illustrates page traversal when multiple pages are
displayed simultaneously by electronic device 100. A continuous
horizontal swipe (i.e., "drag" motion) may be used to traverse
pages 104, 1308, 1310, 1312, and so on. In some exemplary
embodiments, the speed with which the pages are traversed is
related to the speed with which the dragging input is received.
[0104] Continuous horizontal swipe 1302 is shown traversing pages
104, 1308. As columns (e.g., 106, 108, etc.) of the pages are
traversed, the zoom level of the page on which the columns are
located may be adjusted, for example, as described with regard to
FIG. 8. A user may provide input (e.g., release of the continuous
horizontal swipe, a tap input, etc.) at a page to display the
entire page in a full-page mode, as shown at 1304. For example, a
user may tap on page 104 and the selected page 104 can appear on
the display in full-page mode, as shown in 1304.
[0105] A user may provide a different input (e.g., hold position of
continuous horizontal swipe, tap-and-hold, etc.) to display a
column of a page in pan-guide mode. For example, holding a position
at the contact point indicated at 1314 may result in the column at
which the contact point is located being displayed in pan-guide
mode as indicated at 1306.
[0106] FIG. 14 is a flow diagram indicating exemplary method 1400
for transition within a document from displaying a table of
contents view as shown in 1300 to displaying a page in full-page
mode as shown in 1304 or displaying a column in guided-pan mode as
shown in 1306, according to an exemplary embodiment.
[0107] At decision diamond 1401, electronic device 100 may
determine whether the table of contents view of a document is
currently being viewed. If the table of contents view is not
currently being viewed, then flow may return to operation 1401. If
the table of contents view of a document is currently being viewed,
flow may proceed to operation 1402.
[0108] At operation 1402, electronic device 100 can determine
whether a page on the table of contents view is selected. For
example, it is determined whether a user taps on page 104 that is
displayed in the table of contents view. If a page is selected, at
operation 1403, the page can be displayed in full-page mode. The
user can then proceed to view the document in the full-page mode.
If the page is not selected at operation 1402, flow can proceed to
operation 1404.
[0109] At operation 1404, the electronic device 100 can determine
whether a column of a page is selected. For example, it is
determined whether a user selects and holds an area on a column of
a page as identified by, for example, contact point 1314. If a
column of page is selected, the selected column can be displayed in
a guided-pan mode at operation 1405. The user can then proceed to
view the document in the guided-pan mode.
[0110] In some exemplary embodiments, a gravity well is used within
the boundaries of columns (e.g., within the boundaries of column
108 shown in 1008, 1300) to improve the ease with which a column
may be selected. A gravity well can create, for example, a "pull"
towards certain regions of a column, or a previous or subsequent
column. A user can follow the pull of the gravity well or can
choose to navigate to, for example, a different column. For
example, at a region outside of column 108, a first ratio may exist
between a rate of movement (e.g., movement of content or movement
of a display position indicator) displayed by display 102 to the
rate of movement of a pointing indicator. A pointing indicator may
be, e.g., a finger moving along a touch-sensitive surface (e.g., a
touchscreen or touchpad) or movement of a mouse.
[0111] At a region within a column, such as column 108, a second
ratio may be used between a rate of movement of the display
position indicator displayed by display 102 to the rate of movement
of the pointing indicator. The second ratio may be lower than the
first ratio. For example, the first ratio may be 1:1 and the second
ratio may be 1:2, indicating that when the second ratio is in use
(e.g., within a location on display 102 where column 108 is
displayed), a pointing indicator must move twice as far to achieve
the same rate of movement of the displayed position indicator as
when the first ratio is in use (e.g., at a location on display 102
outside of any column regions). The gravity well at the column
location allows a user to select a location within a column with
ease because the pointing indicator moves more slowly within the
selectable column than outside of the column area.
[0112] In some exemplary embodiments, traversal of a media file
(such as an audio file, video file, etc.) corresponding to a
document may occur as column fit document traversal of the same
document occurs. For example, the input received to control column
traversal as described with regard to FIGS. 3-13 may be provided
using a control for traversing a media file, such as scrubber
control, skip control, bookmark control or other control for
navigating to a point within a media file. In some exemplary
embodiments, traversal from a current column to a subsequent column
and/or from a current page to a subsequent page may occur as a
media file is playing. Similarly, traversal between columns and/or
pages may occur as described herein during skipping forward,
skipping back, fast forwarding, rewinding, playing in reverse,
etc., within a media file. In some exemplary embodiments, displayed
column content matches corresponding content of the media file
(e.g., displayed text of a column matches spoken word of a
corresponding audio file during playback of the audio file).
[0113] Various exemplary embodiments of electronic device 100 may
include any of the components described with regard to FIG. 15.
[0114] FIG. 15 is a simplified block diagram of a computer system
1500, according to an embodiment. Electronic device 100 optionally
incorporates various elements as described with reference to FIG.
15. As shown in FIG. 15, computer system 1500 includes one or more
processors 1502 that communicate with a number of subsystems via a
bus subsystem 1504. These subsystems include, for example, a
storage subsystem 1506, user interface input devices 1512, user
interface output devices 1518, and a network interface subsystem
1516.
[0115] Bus subsystem 1504 provides a mechanism for letting the
various components and subsystems of computer system 1500
communicate with each other as intended. Although bus subsystem
1504 is shown schematically as a single bus, alternative exemplary
embodiments of the bus subsystem optionally utilize multiple
busses.
[0116] Processor 1502, which can be implemented as one or more
integrated circuits (e.g., a conventional microprocessor or
microcontroller), controls the operation of computer system 1500.
One or more processors 1502 are provided. These processors
optionally include single core or multicore processors. In various
exemplary embodiments, processor 1502 can execute a variety of
programs in response to program code and can maintain multiple
concurrently executing programs or processes. At any given time,
some or all of the program code to be executed can be resident in
processor(s) 1502 and/or in storage subsystem 1506. Through
suitable programming, processor(s) 1502 can provide various
functionalities described above.
[0117] Network interface subsystem 1516 provides an interface to
other computer systems and networks. Network interface subsystem
1516 serves as an interface for receiving data from and
transmitting data to other systems from computer system 1500. For
example, network interface subsystem 1516 enables computer system
1500 to connect to one or more devices via the Internet. In some
exemplary embodiments network interface 1516 can include radio
frequency (RF) transceiver components for accessing wireless voice
and/or data networks (e.g., using cellular telephone technology,
advanced data network technology such as 3G, 4G or EDGE, WiFi (IEEE
802.11 family standards, or other mobile communication
technologies, or any combination thereof), GPS receiver components,
and/or other components. In some exemplary embodiments network
interface 1516 can provide wired network connectivity (e.g.,
Ethernet) in addition to or instead of a wireless interface.
[0118] User interface input devices 1512 optionally include a
touch-sensitive surface 1522. User interface input devices
optionally further include, pointing devices such as a mouse or
trackball, a touchpad or touch screen incorporated into a display,
a scroll wheel, a click wheel, a dial, a button, a switch, a
keypad, audio input devices such as voice recognition systems,
microphones, and other types of input devices. In general, use of
the term "input device" is intended to include all possible types
of devices and mechanisms for inputting information to computer
system 1500.
[0119] User interface output devices 1518 optionally include a
display subsystem, indicator lights, or non-visual displays such as
audio output devices, etc. The display subsystem includes, for
example, one or more of a cathode ray tube (CRT), a flat-panel
device such as a liquid crystal display (LCD), a projection device,
a touch screen, and the like. In general, use of the term "output
device" is intended to include all possible types of devices and
mechanisms for outputting information from computer system
1500.
[0120] Storage subsystem 1506 provides a computer-readable storage
medium for storing the basic programming and data constructs that
provide the functionality of some exemplary embodiments. Storage
subsystem 1506 can be implemented, e.g., using disk, flash memory,
or any other storage media in any combination, and can include
volatile and/or non-volatile storage as desired. Software
(programs, code modules, instructions) that when executed by a
processor provide the functionality described above are stored in
storage subsystem 1506. These software modules or instructions are
executed by processor(s) 1502. The instructions may optionally be
stored on a non-transitory storage device of storage subsystem 1506
either before or after execution by the processor(s) 1502. Storage
subsystem 1506 also provides a repository for storing data used in
accordance with the exemplary embodiments. Storage subsystem 1506
optionally includes a memory subsystem and a file/disk storage
subsystem.
[0121] A memory subsystem optionally includes a number of memories
including a main random access memory (RAM) for storage of
instructions and data during program execution and a read only
memory (ROM) in which fixed instructions are stored. A file storage
subsystem provides persistent (non-volatile) storage for program
and data files, and include, e.g., a hard disk drive, a floppy disk
drive along with associated removable media, a Compact Disk Read
Only Memory (CD-ROM) drive, an optical drive, removable media
cartridges, and other like memory storage media.
[0122] The computer device 1500 also includes a power system 1524
for powering the various hardware components. The power system 1524
can include a power management system, one or more power sources
(e.g., battery, alternating current (AC)), a recharging system, a
power failure detection circuit, a power converter or inverter, a
power status indicator (e.g., a light emitting diode (LED)) and any
other components typically associated with the generation,
management and distribution of power in mobile devices.
[0123] Computer system 1500 can be of various types including a
personal computer (e.g., a MacBook.RTM., an iMac.RTM.), a portable
device (e.g., an iPhone.RTM., an iPad.RTM.), a workstation, a
network computer, a mainframe, a kiosk, a server or any other data
processing system. Due to the ever-changing nature of computers and
networks, the description of computer system 1500 depicted in FIG.
15 is intended only as a specific example. Many other
configurations having more or fewer components than the system
depicted in FIG. 15 are possible.
[0124] Various exemplary embodiments described above can be
realized using any combination of dedicated components and/or
programmable processors and/or other programmable devices. The
various exemplary embodiments are implementable only in hardware,
or only in software, or using combinations thereof. The various
processes described herein can be implemented on the same processor
or different processors in any combination. Accordingly, where
components or modules are described as being configured to perform
certain operations, such configuration can be accomplished, e.g.,
by designing electronic circuits to perform the operation, by
programming programmable electronic circuits (such as
microprocessors) to perform the operation, or any combination
thereof. Processes can communicate using a variety of techniques
including but not limited to conventional techniques for
interprocess communication, and different pairs of processes
optionally use different techniques, or the same pair of processes
use different techniques at different times. Further, while the
exemplary embodiments described above make reference to specific
hardware and software components, those skilled in the art will
appreciate that different combinations of hardware and/or software
components are also be usable and that particular operations
described as being implemented in hardware might also be
implemented in software or vice versa.
[0125] The various exemplary embodiments are not restricted to
operation within certain specific data processing environments, but
are free to operate within a plurality of data processing
environments. Additionally, although exemplary embodiments have
been described using a particular series of transactions, this is
not intended to be limiting.
[0126] Thus, although specific exemplary embodiments have been
described, these are not intended to be limiting. Various
modifications and equivalents are within the scope of the following
claims.
