DETAILED DESCRIPTION
[0013] The present disclosure describes a smart cover for an
electronic device. The smart cover has a display capability. In
certain embodiments, the smart cover is foldable and includes a
plurality of different segments than can fold (or bend) relative to
each other. In certain embodiments, one or more of the different
segments has a display capability on at least one of the inner and
outer surfaces of the smart cover.
[0014] In certain embodiments, the inner surface of the smart cover
is made of a soft cloth-based material, so that it can provide
proper support and covering of the display surface, and also can be
used as a supporting stand. In certain embodiments, the inner
surface of the smart cover may have a display capability. In these
embodiments, while a user is partially folding the smart cover, the
user can get additional display surface in the partially folded
smart cover along (i.e., in addition to the display surface of the
main electronic device to which the smart cover is attached).
[0015] In certain embodiments, a system and method are provided
where an inner surface of the smart cover is made of an electronic
smart cloth-based material. When folding the smart cover, the inner
surface of the smart cover can also show additional digital content
along with the actual display surface. Use of e-textile (or smart
cloth, or fabric having an electronic display functionality) may
protect the display surface from rubbing action, and at the same
time, can be used for displaying contents
[0016] In certain embodiments, both the inner or outer surfaces of
the smart cover may be made of the e-textile or electronic
cloth-based material, and the smart cover is capable of showing
additional contextual content on both sides of the smart cover.
[0017] In certain embodiments, when a user partially folds the
smart cover, and the folding of the smart cover is towards the
display surface, then the inner visible surface of the smart cover
will be showing additional digital content which is related to the
content displayed in the visible area of the display device of the
main electronic device.
[0018] In certain embodiments, if the folded area of the smart
cover is opposite to the user (i.e., from a different viewing angle
that the user cannot see) or opposite to the display surface of the
main electronic device, then one or more portions of the smart
cover may display additional content to other users who are sitting
on an opposite side of the display device or user.
[0019] In certain embodiments, a user may visualize the folding
pattern of the smart cover, and the user may selectively identify
one or more areas on the folded smart cover where the user wants to
display additional content.
[0020] In certain embodiments, when the smart cover is opened
partially, and the dimension of the displayed content is larger
(i.e., larger than simply the area of the display of the main
electronic device), then the system may consider both the exposed
folded area of the smart cover and the actual display area as an
aggregated display area, and may show the entire aggregated display
area to the user.
[0021] In certain embodiments, the upper surface of the smart cover
may have an e-textile or electronic cloth material. In these
embodiments, summary information of any content may be displayed in
the upper surface of the smart cover. In these embodiments, if the
user wants to have a detailed view of the content, then user may
fold the smart cover. Thus, in certain embodiments, the system may
use both the folded portion of smart cover and the display area of
the electronic device to show the detailed visual content.
[0022] In certain embodiments, based on the confidentiality of the
content in consideration, the upper surface of the smart cover may
show summarized information, notifications etc., and upon folding
the smart cover may show the complete contents of the
information.
[0023] Various embodiments of the present disclosure are described
herein with reference to the related drawings. Alternative
embodiments can be devised without departing from the scope of the
present disclosure. It is noted that various connections and
positional relationships (e.g., over, below, adjacent, etc.) are
set forth between elements in the following description and in the
drawings. These connections and/or positional relationships, unless
specified otherwise, can be direct or indirect, and the present
disclosure is not intended to be limiting in this respect.
Accordingly, a coupling of entities can refer to either a direct or
an indirect coupling, and a positional relationship between
entities can be a direct or indirect positional relationship.
[0024] The following definitions and abbreviations are to be used
for the interpretation of the claims and the specification. As used
herein, the terms "comprises," "comprising," "includes,"
"including," "has," "having," "contains" or "containing," or any
other variation thereof, are intended to cover a non-exclusive
inclusion. For example, a composition, a mixture, process, method,
article, or apparatus that comprises a list of elements is not
necessarily limited to only those elements but can include other
elements not expressly listed or inherent to such composition,
mixture, process, method, article, or apparatus.
[0025] For purposes of the description hereinafter, the terms
"upper," "lower," "right," "left," "vertical," "horizontal," "top,"
"bottom," and derivatives thereof shall relate to the described
structures and methods, as oriented in the drawing figures. The
terms "overlying," "atop," "on top," "positioned on" or "positioned
atop" mean that a first element, such as a first structure, is
present on a second element, such as a second structure, wherein
intervening elements such as an interface structure can be present
between the first element and the second element. The term "direct
contact" means that a first element, such as a first structure, and
a second element, such as a second structure, are connected without
any intermediary conducting, insulating or semiconductor layers at
the interface of the two elements.
[0026] Referring now to the drawings, and initially to FIG. 1, this
figure is a top down view of a device 100 that incorporates a smart
cover. According to certain embodiments, the device 100 includes a
main electronic device 102 and a cover 116 operatively coupled to
the main electronic device 102. The main electronic device 102 may
be a smart phone, a tablet computer, or any other suitable
electronic device that includes some display functionality. As
shown in FIG. 1, the main electronic device 102 includes a main
display 104 device. The main display 104 may be based on any
suitable display technology (e.g., liquid crystal display (LCD), a
light-emitting diode (LED) display, and organic LED (OLED) display,
etc.). In certain embodiments, the cover 116 is a smart cover
having a plurality of different segments. The cover 116 may include
a plurality of different segments (or portions), where one or more
of the segments have a display capability. In certain embodiments,
one or both of the inner surface 112 and outer surface 108 of the
smart cover 116 is made of an electronic smart cloth-based material
that has a display capability.
[0027] In general, a smart cloth (or e-textile) refers to a class
of fabrics that enable digital components and electronics to be
embedded therein. In certain examples, e-textiles may also be
referred to as smart clothing, smart garments, electronic textile
and smart fabrics. According to certain implementations, smart
cloths may be used for communication, they may transform their
shape, they may conduct energy, or they may be used as a display
device. In the present embodiments, such a smart cloth is
implemented as one or more display devices that form a cover for an
electronic device such as a tablet computer.
[0028] Referring again to FIG. 1, the main electronic device 102
includes a display device having a main display area 104. Any sort
of primary display content 106 may be displayed on the main display
area 104. Display content 106 may include images, words, symbols,
or any combination thereof. In certain embodiments, the cover 116
includes a plurality of different foldable segments 116A, 116B, and
116C (or sections) that are independently foldable relative to each
other and relative to the main electronic device 102. In the
example shown in FIG. 1, the cover 116 includes the three separate
foldable segments 116A, 116B, and 116C, each segment including a
smart cloth (or e-textile) capable of displaying certain content.
These segments 116A, 116B, and 116C may fold along a hinge or a
seam in certain examples, and they may be roughly the same size. In
the example shown in FIG. 1, the three segments 116A, 116B, and
116C can fold together to form a triangular prism shape, and they
may provide support for positioning the main electronic device 102
at a certain angle. In other examples, four or more foldable
segments may be used. For example, when the cover 116 is not in a
folded state and is lying flat against the surface of the main
electronic device 102, the entire main display area 104 of the main
electronic device 102 is covered by the cover 116. In this unfolded
state, in certain embodiments, summary display content may be
viewed on an outer surface 108 of one or more of the foldable
segments 116A, 116B and 116C of the cover 116. This summary display
content may be viewed on any or all of the plurality of segments of
the cover 116.
[0029] As shown in top-down view of the example of FIG. 1, a first
one of the segments 116C has been folded to reveal a portion of the
main display area 104. In addition, in this folded state, the outer
surface 108 of the foldable segment 116C is hidden from the
viewer's perspective. In addition, an inner surface 110 of one of
the foldable segments includes a smart cloth that has a cover
display area 112. In this example, a viewing angle of the viewer of
the main electronic device 102 originates from the positive Z
direction (i.e., from the right side in FIG. 1). From this viewing
angle, the user can view not only the revealed portion of the main
display area 104, but also display indicia 114 appearing in the
display area 112 of the revealed segment 116C of the smart cover
116. In this example, the inner surface 110 of the folded segment
has the cover display area 112 activated because it is been
determined that the viewer is able to view that portion of the
inner surface 110 from the particular viewing angle (i.e., from the
positive Z direction).
[0030] In certain embodiments, when the smart cover 116 is opened
partially, and the dimension of the displayed content is larger
(i.e., larger than simply the area of the main display area 104 of
the electronic device 100), then the system may consider both the
exposed folded area of the smart cover 116 and the actual display
area as an aggregated display area, and may show the entire
aggregated display area to the user. In this example, the revealed
portion of the main display area 104 as well as the display area
112 of the folded segment 116C may be aggregated together. Thus, a
larger cumulative area may be used to display content. As
additional sections of the cover 116 are folded away from the main
display 104, additional inner surfaces of folded segments 116B and
116A may appear in the viewing direction of the user, and the
display areas thereof (not shown in FIG. 1) may also be activated
and considered with regard to determining an aggregated display
area.
[0031] Referring now to FIGS. 2A-2C, different perspective views of
the main electronic device 200 are shown with the cover segments
216A-216D in various folding configurations of the cover 216. In
this example, there are four cover segments 216A-216D (contrary to
the three segments 116A, 116B and 116C shown in FIG. 1). In FIG.
2A, the device 200 includes an electronic device 202 having a
display device with a main display area 204. In certain
embodiments, the cover 216 includes the different foldable segments
216A, 216B, 216C, and 216D (or sections) that are independently
foldable relative to each other and relative to the main electronic
device 202. In the example shown in FIGS. 2A-2C, the cover 216
includes four separate foldable segments 216A, 216B, 216C, and
216D, each including a smart cloth (or e-textile) capable of
displaying certain content. These segments 216A, 216B, 216C, and
216D may fold along a hinge or a seam 208 between adjacent segments
in certain examples, and they may be roughly the same size.
[0032] In the embodiment shown in FIG. 2A, the smart cover 216 is
in a partial state of folding, where each of segments 216B, 216C
and 216D have been partially folded away from the main display area
204 of the electronic device 202. Also, in FIG. 2A, segment 216A of
the cover has not been folded away from the main display area 204
of the electronic device 202. In this example, it has been
determined to activate the display area 212 on the outside surface
206 of segment 216A. As shown in FIG. 2A, any suitable indicia may
be displayed in the display area 212. It should be appreciated that
this is merely one example of activating a particular display area
of the cover 216, and one or more other segments 216B, 216C and
216D may also (or alternatively) activated. In certain embodiments,
the angle of the segment relative to the planar surface of the
display device (i.e., main display area 204) may be a factor in
determining whether a particular segment is activated or not. For
example, a viewing angle of an opposed viewer (i.e., a person
opposed to the person viewing the main display area 204 of the
electronic device 202) may be taken into consideration when
determining which segments to activate.
[0033] Referring now to FIG. 2B, a smart cover 216 is in a more
complete state of folding, where each of segments 216B, 216C and
216D have been further folded away from the main display area 204
of the electronic device 202. In this example, segment 216B has
been folded to a sufficient degree such that the viewer of the main
display area 204 is also able to view the display area 218 of
segment 216C. Because the system has determined that segment 216C
has been folded to a sufficient degree to enable the viewer of the
main display area 204 view the display area 218, this display area
218 is activated. In this example, it is the inner surface 210 of
segments 216C that has the smart cloth activated. Also, because the
system has determined that segment 216B has been folded to a
sufficient degree to enable the opposed viewer to view the display
area 220, this display area 220 is activated also. In this example,
it is the outer surface 206 of segment 216B that has the smart
cloth activated. Thus, it should be appreciated that different
segments of both the inner surface 210 of the smart cloth and
different segments of the outer surface 206 of the smart cloth can
be activated simultaneously based on the ability of one or both of
the viewer and the opposed viewer to actually see the respective
display areas.
[0034] Referring now to FIG. 2C, the smart cover 216 is in a
complete state of folding (i.e., in the general shape of triangular
prism), where each of segments 216A, 216B, 216C and 216D have been
further folded away from the main display area 204 of the
electronic device 202. In this example, segment 216D has been
folded back and is resting against the surface of segment 216A.
Also, in this example, no portion of the inner surface 206 of any
segment of the cover 216 is viewable by either main viewer or the
opposed viewer. Consequently, none of the display areas on the
inner surface 206 of the cover 216 are activated. Although not
shown in FIG. 2C, one or more of the outer surfaces 210 of segments
216A, 216B and 216C may be activated depending on the calculated
positions (or viewing angles) of the viewer and the opposed viewer.
In certain embodiments, one or more image capturing devices may be
included on the main electronic device 202 and/or the cover 216 to
determine the positions of the different viewers relative to the
positions of the segments 216A, 216B, 216C and 216D.
[0035] Referring now to FIGS. 3A and 3B, additional perspective
views of the main electronic device 300 are shown, where the
completely folded cover 318 provides different methods of
supporting the electronic device 302 at different angles or
positions. As shown in FIG. 3A, the smart cover 318 includes an
inner surface 310 and an outer surface 312. The electronic device
302 includes a display device 304 having a display area 306. As
shown in FIG. 3A, the completely folded cover 318 forms a roughly
triangular prism shape that allows the main electronic device 302
to be propped up at a slight angle relative to the X-Z plane. In
this embodiment, the viewer 320 has a viewing angle (i.e., having a
viewing angle extending in the general Z-axis direction and
slightly down in the Y-axis direction) sufficient to view the
display area 306 on the main electronic device 302. Also, an
opposed viewer 322 is able to view the backside of the folded cover
318 (i.e., having a viewing angle extending in the general Z-axis
direction). Thus, in this example one of the segments of the smart
cover 318 may be activated and visible to the opposed viewer 322.
FIG. 3B shows an example where such a segment has a display area
314 showing indicia 316, and is visible to the opposed viewer 322,
but is not visible to the viewer 320. Also, in the example shown in
FIG. 3B, the completely folded smart cover 318 supports the main
electronic device 302 at a much steeper angle. It should be
appreciated that the embodiments described herein are not limited
to the example configurations shown in FIGS. 2A-2C and 3A-3B. There
may be any number suitable of segments of the cover, and the cover
may be configured in any suitable angular orientation or shape.
However, in certain of the embodiments described herein a common
feature is that the smart cover has the ability to display content
on one or more display areas of cover segments such that either the
viewer 320 or the opposed viewer 322 can view the segments in
addition to the content on the main display device 308.
[0036] Referring now to FIG. 4, a schematic representation of the
main electronic device 400 and the smart cover 420 is shown. As
shown in FIG. 4, the main electronic device 400 may include a power
supply 410, a segment position determiner 414, a central processing
unit or CPU 412, and a segment display element controller 416,
according to embodiments. The main electronic device 400 is
operatively coupled to the smart cover 420 via a communications
line 422 (e.g., a system bus or some other communication mechanism
that allows for transfer of power and information). In certain
embodiments, as shown in FIG. 4, the power supply 410 of the main
electronic device 400 supplies power not only to a display device
of the main electronic device 400, but also to be display elements
of smart cover 420. The smart cover 420 includes a plurality of
cover segments 418-1, 418-2, 418-3 and 418-4. Each of these
segments includes a front display element 450 (configured to
display indicia on an outer surface of the smart cover 420) and a
rear display element 452 (configured to display indicia on an inner
surface of the smart cover 420). In certain embodiments, each of
the cover segments 418-1, 418-2, 418-3 and 418-4 includes one or
more position sensors 454. As discussed above, the position sensors
454 enable a determination of a position and/or angular orientation
of the individual segments 418-1, 418-2, 418-3 and 418-4.
Alternatively, sensors can be located in a different location or in
different numbers provided that information regarding the position
and/or angular orientation of the segments may be determined. In
certain embodiments, information from the position sensors 454 are
transferred through the communications line 422 to the main
electronic device 400. Then, the segment position determiner 414
uses the information from the position sensors 454 to determine the
positions of the different segments. Once the positions of the
different segments been determined by the segment position
determiner 414, the segment display element controller 416 causes
each of the cover segments 418-1, 418-2, 418-3 and 418-4 to turn
off or on depending upon the determined view ability angles of the
main viewer and/or the opposed viewer. The main electronic device
400 may be the exemplary processing system discussed below with
respect to FIG. 5.
[0037] Referring now to FIG. 5, an exemplary processing system 500
to which the present embodiments may be applied is shown in
accordance with one embodiment. The processing system 500 includes
at least one processor (CPU) 504 operatively coupled to other
components via a system bus 502. A cache 506, a Read Only Memory
(ROM) 508, a Random-Access Memory (RAM) 510, an input/output (I/O)
adapter 520, a sound adapter 530, a network adapter 540, a user
interface adapter 550, and a display adapter 560, are operatively
coupled to the system bus 502.
[0038] A first storage device 522 and a second storage device 524
are operatively coupled to system bus 502 by the I/O adapter 520.
The storage devices 522 and 524 may be any of a disk storage device
(e.g., a magnetic or optical disk storage device), a solid-state
magnetic device, and so forth. The storage devices 522 and 524 may
be the same type of storage device or different types of storage
devices.
[0039] A speaker 532 is operatively coupled to system bus 502 by
the sound adapter 530. A transceiver 542 is operatively coupled to
system bus 502 by network adapter 540. A display device 562 is
operatively coupled to system bus 502 by display adapter 560.
[0040] A first user input device 552, a second user input device
554, and a third user input device 556 are operatively coupled to
system bus 502 by user interface adapter 550. The user input
devices 552, 554, and 556 may be any of a keyboard, a mouse, a
keypad, an image capture device, a motion sensing device, a
microphone, a device incorporating the functionality of at least
two of the preceding devices, or any other suitable types of input
devices. The user input devices 552, 554, and 556 may be the same
type of user input device or different types of user input devices.
The user input devices 552, 554, and 556 are used to input and
output information to and from system 500. In certain embodiments,
the smart cover component 570 is operatively coupled to system bus
502.
[0041] The processing system 500 may also include other elements
(not shown), as readily contemplated by one of skill in the art, as
well as omit certain elements. For example, various other input
devices and/or output devices may be included in processing system
500, depending upon the particular implementation of the same, as
readily understood by one of ordinary skill in the art. For
example, various types of wireless and/or wired input and/or output
devices can be used. Moreover, additional processors, controllers,
memories, and so forth, in various configurations can also be
utilized as readily appreciated by one of ordinary skill in the
art. These and other variations of the processing system 500 are
readily contemplated by one of ordinary skill in the art given the
teachings of the present disclosure provided herein.
[0042] In certain embodiments, the processing system 500 may
perform one or more functions related to the operation of the main
electronic device 400 including the smart cover 420. For example,
CPU 504 of the processing system 500 may correspond to the CPU 412
of the main electronic device 400 shown in FIG. 4. Thus, the CPU
504 may perform functions of the main electronic device 400 such as
determining the position of the segments in conjunction with the
segment position determiner 412 and/or controlling the on/off
display configuration of the different segments in conjunction with
the segment display element controller 412. In certain embodiments,
the processing system 504 may be a part of the main electronic
device 400.
[0043] Referring now to FIG. 6, a flowchart is shown of a method
600 of controlling the display of a smart cover for an electronic
device, according to certain embodiments. At operation 602, the
method begins. At operation 604, the method includes determining a
folding state of a smart cover of an electronic device, the smart
cover including an electronic cloth-based material on an inner
surface of the cover and an outer surface of the cover. At
operation 606, the method includes determining a viewability of
different portions (or smart cover folding segments) of the inner
surface of the cover in a viewing direction of the cover and of
different portions of the outer surface of the cover in the viewing
direction. At operation 608, the method includes determining a
viewability of different portions (or smart cover folding segments)
of the inner surface of the cover in an opposed viewing direction
that is opposed to the viewing direction and of different portions
of the outer surface of the cover in the opposed viewing direction.
At operation 610, the method includes enabling (or disabling) the
display of different portions of the inner surface and outer
surface of the smart cover based on the viewability determinations
made in operations 606 and 608. In certain embodiments, if a
segment of the smart cover is viewable in the primary viewing
direction (or the opposed viewing direction), the method includes
causing the display elements associated with the viewable surface
of the respective segment to display content. Likewise, if a
segment of the smart cover is not viewable in the primary viewing
direction (or the opposed viewing direction), the method includes
causing the display elements associated with the viewable surface
of the respective segment to not display any content (i.e., turn
off). At operation 612, the method includes determining (e.g., with
one or more sensors incorporated into the smart cover) whether or
not there has been any change in the folding state (or folding
configuration). If there has not been any change in the folding
state (612:NO), the process ends at operation 614. If there has
been a change in the folding state (612:YES), the process returns
to operation 604 to once again determine the folding state of the
smart cover.
[0044] The present invention may be a system, a method, and/or a
computer program product at any possible technical detail level of
integration. The computer program product may include a computer
readable storage medium (or media) having computer readable program
instructions thereon for causing a processor to carry out aspects
of the present invention.
[0045] The computer readable storage medium can be a tangible
device that can retain and store instructions for use by an
instruction execution device. The computer readable storage medium
may be, for example, but is not limited to, an electronic storage
device, a magnetic storage device, an optical storage device, an
electromagnetic storage device, a semiconductor storage device, or
any suitable combination of the foregoing. A non-exhaustive list of
more specific examples of the computer readable storage medium
includes the following: a portable computer diskette, a hard disk,
a random access memory (RAM), a read-only memory (ROM), an erasable
programmable read-only memory (EPROM or Flash memory), a static
random access memory (SRAM), a portable compact disc read-only
memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a
floppy disk, a mechanically encoded device such as punch-cards or
raised structures in a groove having instructions recorded thereon,
and any suitable combination of the foregoing. A computer readable
storage medium, as used herein, is not to be construed as being
transitory signals per se, such as radio waves or other freely
propagating electromagnetic waves, electromagnetic waves
propagating through a waveguide or other transmission media (e.g.,
light pulses passing through a fiber-optic cable), or electrical
signals transmitted through a wire.
[0046] Computer readable program instructions described herein can
be downloaded to respective computing/processing devices from a
computer readable storage medium or to an external computer or
external storage device via a network, for example, the Internet, a
local area network, a wide area network and/or a wireless network.
The network may comprise copper transmission cables, optical
transmission fibers, wireless transmission, routers, firewalls,
switches, gateway computers and/or edge servers. A network adapter
card or network interface in each computing/processing device
receives computer readable program instructions from the network
and forwards the computer readable program instructions for storage
in a computer readable storage medium within the respective
computing/processing device.
[0047] Computer readable program instructions for carrying out
operations of the present invention may be assembler instructions,
instruction-set-architecture (ISA) instructions, machine
instructions, machine dependent instructions, microcode, firmware
instructions, state-setting data, configuration data for integrated
circuitry, or either source code or object code written in any
combination of one or more programming languages, including an
object oriented programming language such as Smalltalk, C++, or the
like, and procedural programming languages, such as the "C"
programming language or similar programming languages. The computer
readable program instructions may execute entirely on the user's
computer, partly on the user's computer, as a stand-alone software
package, partly on the user's computer and partly on a remote
computer or entirely on the remote computer or server. In the
latter scenario, the remote computer may be connected to the user's
computer through any type of network, including a local area
network (LAN) or a wide area network (WAN), or the connection may
be made to an external computer (for example, through the Internet
using an Internet Service Provider). In some embodiments,
electronic circuitry including, for example, programmable logic
circuitry, field-programmable gate arrays (FPGA), or programmable
logic arrays (PLA) may execute the computer readable program
instructions by utilizing state information of the computer
readable program instructions to personalize the electronic
circuitry, in order to perform aspects of the present
invention.
[0048] Aspects of the present invention are described herein with
reference to flowchart illustrations and/or block diagrams of
methods, apparatus (systems), and computer program products
according to embodiments of the invention. It will be understood
that each block of the flowchart illustrations and/or block
diagrams, and combinations of blocks in the flowchart illustrations
and/or block diagrams, can be implemented by computer readable
program instructions.
[0049] These computer readable program instructions may be provided
to a processor of a computer, or other programmable data processing
apparatus to produce a machine, such that the instructions, which
execute via the processor of the computer or other programmable
data processing apparatus, create means for implementing the
functions/acts specified in the flowchart and/or block diagram
block or blocks. These computer readable program instructions may
also be stored in a computer readable storage medium that can
direct a computer, a programmable data processing apparatus, and/or
other devices to function in a particular manner, such that the
computer readable storage medium having instructions stored therein
comprises an article of manufacture including instructions which
implement aspects of the function/act specified in the flowchart
and/or block diagram block or blocks.
[0050] The computer readable program instructions may also be
loaded onto a computer, other programmable data processing
apparatus, or other device to cause a series of operational steps
to be performed on the computer, other programmable apparatus or
other device to produce a computer implemented process, such that
the instructions which execute on the computer, other programmable
apparatus, or other device implement the functions/acts specified
in the flowchart and/or block diagram block or blocks.
[0051] The flowchart and block diagrams in the Figures illustrate
the architecture, functionality, and operation of possible
implementations of systems, methods, and computer program products
according to various embodiments of the present invention. In this
regard, each block in the flowchart or block diagrams may represent
a module, segment, or portion of instructions, which comprises one
or more executable instructions for implementing the specified
logical function(s). In some alternative implementations, the
functions noted in the blocks may occur out of the order noted in
the Figures. For example, two blocks shown in succession may, in
fact, be accomplished as one step, executed concurrently,
substantially concurrently, in a partially or wholly temporally
overlapping manner, or the blocks may sometimes be executed in the
reverse order, depending upon the functionality involved. It will
also be noted that each block of the block diagrams and/or
flowchart illustration, and combinations of blocks in the block
diagrams and/or flowchart illustration, can be implemented by
special purpose hardware-based systems that perform the specified
functions.
[0052] In certain embodiments, both sides (i.e., an inside surface
and an outside surface) of the smart cover of, for example, a
tablet based electronic device includes a layer of e-textile or
electronic cloth-based material.
[0053] In certain embodiments, the e-textile material is capable of
displaying digital content. The content display capability on the
e-textile material depends on how the e-textile is designed. In
certain embodiments, the e-textile material also has touch
sensitivity. Therefore, in these embodiments, the e-textile
material can also detect a touch action from a user.
[0054] In certain embodiments, the e-textile material is cloth
like. For example, in different applications for e-textile
materials, the material can be incorporated into a wearable article
such as a dress or article of clothing. Therefore, the smart cover
of the present embodiments having the e-textile material will have
enhanced capabilities by being able to display digital content.
[0055] In certain embodiments, in the smart cover, the surface area
may have multiple foldable capabilities horizontally (e.g., three
or four foldable areas).
[0056] In certain embodiments, a single cover display device (e.g.,
an e-textile) extends across all of the foldable areas of the
cover. In this regard, in the example of a four segment cover, a
single e-textile covers the entire inside surface or the entire
outside surface of the cover. In one example, a flexible OLED
display device is used that may bend. In other examples, each
surface of each segment of the cover includes a separate display
device, which are all operatively connected together and to the
main electronic device.
[0057] In certain embodiment, the smart cover may have electric
connectivity with the display device of the main electronic
device.
[0058] In certain embodiments, when the smart cover is connected to
the main electronic device, then it will be directly connected to
the display device thereof, and consuming battery power associated
with the main electronic device.
[0059] In certain embodiments, when a user folds a portion of the
smart cover, then the display areas thereof will be exposed
[0060] In certain embodiments, when the smart cover is folded, then
display device may start to emit the digital content, and with
closing of the smart cover, the display device may stop emitting
the digital content.
[0061] In certain embodiments, the smart cover may recognize each
and every fold portion individually, and various sensors can be
used for measuring the fold angle in the smart cover.
[0062] In certain embodiments, at any point of time, the display
device of the main electronic device (e.g., a tablet computer) may
communicate with the smart cover, and it may identify how the smart
cover is folded along with the shape of the folded smart cover.
[0063] In certain embodiments, based on the determined folded
condition of the smart cover, the display device of the main
electronic device may identify the relative position of the folded
smart cover with respect to the display surface of the display
device.
[0064] In certain embodiments, the display device and smart cover
communicate with each other and the relative position and folded
condition will be communicated with the display device.
[0065] In certain embodiments, if the smart cover is totally
covering the display surface (e.g., not folded), then only the
outer surface of the smart cover may display content.
[0066] In certain embodiments, when the smart cover is covering the
display device of the main electronic device, and any confidential
message is to be shown, then the display device may communicate
with the upper surface of the smart cover, and only summary
information or notifications will be shown to the user.
[0067] In certain embodiments, based on the folding pattern of the
smart cover, the display device and smart cover may identify which
portion of the display surface is visible to the user, and which
portion of the smart cover is visible to the user.
[0068] In certain embodiments, the system may the folding pattern
of the smart cover and accordingly calculate a 3D model of the
smart cover, and the angular orientation of same.
[0069] The descriptions of the various embodiments have been
presented for purposes of illustration and are not intended to be
exhaustive or limited to the embodiments disclosed. Many
modifications and variations will be apparent to those of ordinary
skill in the art without departing from the scope and spirit of the
described embodiments. The terminology used herein was chosen to
best explain the principles of the embodiments, the practical
application or technical improvement over technologies found in the
marketplace, or to enable others of ordinary skill in the art to
understand the embodiments disclosed herein.
