distinguished from the electronic personal display Can interact directly with the electronic
personal display. Some examples of electronic personal displays are portable digital devices /
tablet computers (e.g., Apple iPad (R), Microsoft (R) (R), Surface (R), Samsung Galaxy Tab)
(Samsung Galaxy Tab) (registered trademark), handheld multimedia smartphones (eg, Apple
iPhone (registered trademark), Samsung Galaxy S (registered trademark), etc.), and handheld
Electronic readers (for example, Amazon Kindle (registered trademark), Barnes and Noble Nook (
Recorded trademark), including the Kobo Aura HD, etc.).
[0003]
[0002]
Electronic readers, also known as e-readers, are electronic personal displays used to read
electronic books (ebooks), electronic magazines, and other digital content. For example, the
digital content of the e-book is displayed as characters and / or images on the display device of
the e-reader, whereby the user reads the digital content in much the same way as reading the
analog content of the printed surface of the paper book be able to. e-readers provide a
convenient format for storing, transporting, and viewing large amounts of digital content that
would otherwise occupy large volumes of space in conventional paper formats.
[0004]
[0003]
In some cases, an e-reader is a dedicated device designed to perform particularly well when
displaying textual digital content (i.e., character strings). For example, a dedicated e-reader may
include a display that reduces glare, works well in high light conditions, and / or mimics the
appearance of a string printed on an actual paper. Such a dedicated e-reader may be excellent for
displaying textual digital content for the user to read, but a dedicated e-reader may, inter alia,
display images, emit sound, capture sound, Other functions such as digital image capture and
web browsing can also be performed.

sensing operates to detect an input object that blocks one or more infrared beams being fired to
a surface, such as the outer surface 121, the back surface 115, and / or the housing 110, and
other surfaces. .
[0021]
[0027]
Once the interaction of the input object is detected by the tactile sensor 230, it is interpreted by
a dedicated processor (e.g. an application specific integrated circuit (ASIC)) coupled with the
tactile sensor 230 such that the interaction is of the eReader 100. Either passed to the processor

sensors are included, user input from a combination of interaction of the input object with both
front and back tactile sensors May be received and interpreted.
[0024]
[0030]
Similarly, in some embodiments, if left side tactile sensor 230-3 and / or right side tactile sensor
230-4 are included, the housing may be configured to receive user input from one or more input
objects 201. It may be placed close to the respective left and / or right sides (114, 113) of the

[0026]
[0032]
Still referring to FIG. 2, a detail view 220 depicts a display device 120 according to some
embodiments.
Details 220 illustrate a portion of the bistable electronic ink used when the display 120 is a
11-04-2019
9
bistable display in some embodiments. In some embodiments, the bi-stable display is a reflective
display to present images such as paper and ink and / or a light emitting display, and thus the
display 120 is powered. Even when not being used, the display device 120 can present a
continuous image, so it is used for the e-reader 100. In one embodiment, the bistable display
comprises an infinite number of fines filled with an optically clear liquid 224 in which positively
charged white pigment particles 225 and negatively charged black pigment particles 226 are
suspended. Electronic ink in the form of an optically clear capsule 223 is provided. The capsule
223 is disposed between the bottom electrode 222 and the permeable top electrode 221. A
transparent / optically transparent protective surface is often disposed over the top electrode
221 and, if included, this additional transparent surface forms the outer surface 121 of the
display 120 and a contact for receiving the touch input Form a face. It should be appreciated that
one or more intervening transparent / optically transparent layers may be disposed between the
outer surface 121 and the top electrode 221. In some embodiments, one or more of these
intervening layers may include patterned sensors and / or electrodes of tactile sensor 230-1.
When a positive or negative electric field is applied close to each of the bottom electrode 222
and the top electrode 221 in a region close to the capsule 223, pigment particles of the opposite
polarity to a certain electric field are attracted to the electric field, Pigment particles of the same
polarity as the applied electric field are repelled from the electric field. Therefore, when a
positive charge is applied to the top electrode 221 and a negative charge is applied to the bottom
electrode 222, the black pigment particles 226 rise to the top of the capsule 223 and the white
pigment particles 225 move to the bottom of the capsule 223. Thereby, the outer surface 121
appears black at a point above the capsule 223 on the outer surface 121. Conversely, when a
negative charge is applied to the top electrode 221 and a positive charge is applied to the bottom
electrode 222, the white pigment particles 225 rise to the top of the capsule 223 and the black
pigment particles 226 move to the bottom of the capsule 223. This causes the outer surface 121
to appear white at points above the capsule 223 on the outer surface 121. It should be
appreciated that variations of this technique can be utilized, using pigment particles of three or
more colors.
[0027]
[0033]
FIG. 3 is a cross-sectional view of an e-reader illustrating an example of tactile sensor 230,
according to one embodiment. In FIG. 3, a portion of the display device 120 has been removed so
that a portion of the top sensor 230-1 in the lower layer is visible. As shown, in one embodiment,
the top tactile sensor 230-1 is shown as an x-y grid of sensor electrodes that can be used to
perform various techniques of capacitive sensing. For example, sensor electrodes 331 (visible in
view 331-0, 331-1, 331-2 and 331-3) are arranged along a first axis while sensor electrodes 332
(visible in view) In this, 332-0, 332-1, 332-2, and 332-3) are arranged along a second axis that is
11-04-2019
10
substantially perpendicular to the first axis. It should be appreciated that a dielectric layer (not
shown) is disposed between all or part of the sensor electrodes 331 and 332 to prevent shorts.
The sensor electrode patterns (331, 332) shown in FIG. 3 provide only an example, various other
patterns may be utilized as well, and some of these patterns It should also be understood that
only sensor electrodes arranged in one layer may be utilized. Additionally, although the example
of FIG. 3 shows top electrode 230-1 as being disposed below display 120, in other embodiments,
portions of tactile sensor 230-1 may be transparent. , May be disposed on the display device 120
or may be integrated with the display device 120.
[0028]
[0034]
In another embodiment, performing absolute / self-capacitive sensing with the first on-axis
sensor electrode 331 can form a first profile of any input object that contacts the outer surface
121. Then, by performing absolute / self-capacitive sensing at the sensor electrode 332, a second
profile of any input object contacting the outer surface 121 can be formed on orthogonal axes.
These volumetric profiles can be processed to determine the occurrence and / or position of user
input provided by the input object 201 in contact or proximity with the outer surface 121.
[0029]
[0035]
In another embodiment, the outer surface 121 is contacted by performing transcapacitive /
mutual capacitive sensing between the first on-axis sensor electrode 331 and the second on-axis
sensor electrode 332. A volumetric image of any input object can be formed. This volumetric
image can be processed to determine the occurrence and / or location of user input provided by
the input object touching or in close proximity to the outer surface 121.
[0030]
[0036]Mutual capacitive sensing may be considered as a better technique for detecting multiple
simultaneous input objects in contact with a surface such as the outer surface 121 while absolute
capacitive sensing may be considered as a surface such as the outer surface 121 It should be
appreciated that it can be considered as a better technique for detecting the proximity of an
object that is near but not necessarily in contact.
11-04-2019

[0031]
[0037]In some embodiments, capacitive sensing and to detect touch input across all or part of
the back surface 115 of the e-reader 100 and / or any other surface (s) of the housing 110 And /
or other touch sensing techniques may be used.

In another embodiment, manual input is used to notify the terminal (e.g., e-reader 100) that it is
in reader mode. For example, manual input may be received via a hard button, such as the user
pressing a button designated as a reader mode. Alternatively, manual input may be received via a
tactile sensor, such as a capacitive sensor. For example, the user may touch a soft button or
perform a gesture on a capacitive sensor to notify a terminal (e.g., e-reader 100) to enter a reader
mode.
[0050]
[0056]
Referring now to step 710 of FIG. 7 and FIG. 5, one embodiment detects ambient noise around
the terminal. For example, a terminal such as the e-reader 100 may use the microphone 160 to
detect the amplitude and frequency of ambient noise. In one embodiment, the microphone 160
may be a single front-facing microphone fixedly coupled to the e-reader 100. In another

combined.
[0051]
[0057]
Referring now to step 715 of FIG. 7 and FIG. 5, one embodiment generates a noise canceling
sound wave at the terminal to reduce distraction from ambient noise. Generally, and for purposes
of illustration only and referring to the e-reader 100, upon receiving ambient noise via the
microphone 160, the noise removal module 620 determines the frequency and amplitude and
then to the speaker 150 to the original sound. A signal is generated that emits sound waves of
the same amplitude but reversed in phase. The two waves combine to form a new wave in a
process called interference, effectively canceling each other.
[0052]
[0058]
11-04-2019
18
Referring now to step 720 of FIG. 7 and FIG. 5, one embodiment outputs a noise canceling sound
wave from at least one speaker coupled to the terminal. In one embodiment, the noise
cancellation sound waves are output from one front-facing speaker 150 that is fixedly coupled to
a terminal device such as the e-reader 100. In another embodiment, the noise canceling sound
waves are output from a pair of front facing speakers 150 fixedly coupled to a terminal device
such as the e-reader 100. In yet another embodiment, the noise canceling sound waves are
output from at least one speaker 565 that is removably coupled to a terminal device such as the
e-reader 100. For example, the speaker 565 may be connected to the e-reader 100 by wire or
wirelessly. For example, the speaker 565 may be connected to the headphone socket in the ereader 100 or wirelessly with the e-reader 100 via Bluetooth®, Wi-Fi, or other short-range
wireless communication protocol It may be combined. In another embodiment, the noise
canceling sound wave is output from some combination of a speaker fixedly coupled to the

The descriptions of the above embodiments are not intended to be exhaustive or to limit the
embodiments to the precise forms disclosed. Rather, the exemplary embodiments in the
description of this embodiment are presented to enable a person skilled in the art to make and
use the described embodiments of the subject matter. Furthermore, various embodiments are
described in various combinations. However, any two or more embodiments may be combined.
While certain embodiments are described in language specific to structural features and / or
methodical acts, the subject matter defined in the appended claims is not necessarily limited to
the specific features described above. Should be understood. Rather, the specific features and
acts described above are disclosed by way of example and as an example implementation of the
claims and their equivalents.
[0054]
(Determination of Reader Mode) Next, the determination of the reader mode will be described in
more detail. As described above, the reading mode determination unit 610 determines that the
terminal device such as the e-reader 100 is in the reader mode. The reader mode is a reading
state in which it is estimated that the user is reading an electronic book. If it is determined that
the reader mode is selected, the e-reader 100 outputs a noise-cancelled sound wave capable of
11-04-2019
19
reducing ambient noise. When the electronic book is displayed on the display device 120 of the
e-reader 100, the reading mode determination unit 610 may determine that the state of the
terminal device is the reader mode. Specifically, for example, when the e-reader 100 starts
reading, the user operates the e-reader 100 to display any page of the electronic book. The
reading mode determination unit 610 can determine that the reader mode is set when the page
of the electronic book is displayed. This determination is performed, for example, in step 705 of
FIG.
[0055]
In addition, the reading mode determination unit 610 may determine that the reader mode is set
when the electronic book is displayed on the display device 120 of the e-reader 100 for a
predetermined time or more set in advance. This makes it possible to more accurately determine
that reading is being performed reliably. The predetermined time for this determination may be
set to, for example, several minutes.
[0056]
(Stop Control of Noise Canceling Sound Wave) Next, stop control of the output of the noise
canceling sound wave 530 will be described. The reading mode determination unit 610 can
determine that the user is not reading an electronic book, that is, not in a reading mode, that is,
not in a reading mode, when the user does not detect an operation on the e-reader 100 for a
predetermined time. If it is determined that the reader mode is not set, the noise removal module
620 may stop the generation of the noise cancellation sound wave 530 and the output of the
noise cancellation sound wave from the speaker. By such control, the output of the noise
cancellation sound wave 530 is stopped when there is a high possibility that the user is not
reading by the e-reader 100, so the consumption of power in the e-reader 100 is suppressed.
[0057]
The reading mode determination unit 610 may also determine that the reader mode is not set
when the user does not detect a page turning operation on the electronic book displayed on the
e-reader 100 for a predetermined time. In this case, it is possible to determine with high accuracy
the state in which the user is not reading an electronic book.
11-04-2019
20
[0058]
The stop control of the output of the noise cancellation sound wave 530 will be described with
reference to FIG. In step 805, the reading mode determination unit 610 determines whether the
state of the e-reader 100 is the reader mode. If it is determined that the reader mode is set, the
process proceeds to step 810. If it is not determined that the reader mode has been entered, the
determination process is repeated.
[0059]
The process of steps 810 to 820 is the same as the process of steps 710 to 720 in FIG.
[0060]
In step 825, the reading mode determination unit 610 determines whether the reading mode is
not the reader mode.
If it is determined to be in the non-reading state, the process proceeds to step 830. If it is not
determined to be in the non-reading state, the processing of steps 810 to 820 is repeated, and
the noise canceling sound wave 530 is output.
[0061]
In step 830, the noise removal module 620 stops the generation of the noise cancellation sound
wave, and the output of the noise cancellation sound wave by the speaker 150 is stopped.
[0062]
(Output Control of Noise-Cancelled Sound Wave) Next, an example of control of the output of the
noise-cancelled sound wave will be described.
The noise removal module 620 may perform control to generate a noise canceling sound wave
530 when the microphone 160 detects the ambient noise 525 having a volume equal to or
11-04-2019
21
higher than a predetermined threshold. As a result, since the noise canceling sound wave 530 is
output from the speaker 150 when the ambient noise 525 having a predetermined volume or
higher is generated, it is possible that the noise canceling sound wave is generated when the
probability that the user's reading is interrupted by the ambient noise is high. Ambient noise can
be reduced.
[0063]
Then, the noise removal module 620 may be configured to generate the noise canceling sound
wave 530 when an event indicating that the user is concentrating on reading the electronic book
is detected, as compared to the case where such an event is not detected. The threshold value of
the volume of ambient noise may be set high.
[0064]
When the user is concentrating on reading, relatively small noise is unlikely to inhibit reading.
In such a case, by setting the threshold of the volume of ambient noise high for the generation of
the noise canceling sound wave 530, it is possible to suppress the output of the noise canceling
sound wave 530 more than necessary. An event indicating that the user is concentrating on
reading is, for example, after a predetermined time has elapsed from the start of reading, and
when page turning is stably performed, etc. And the processor 406 and the like.
[0065]
(Display to User When Specific Sound is Detected) Next, display processing for the user when
specific sound is detected will be described. When the e-reader 100 is controlled to the reader
mode and the noise canceling sound wave 530 is output, all sounds generated around the user
are reduced, so the user should recognize even while reading. Sound will also be reduced. The ereader 100 can perform processing for displaying to the user that a sound to be recognized by
the user is generated.

FIG. 9 is a functional block diagram of the ambient noise minimization device 600A capable of
realizing such display processing. The ambient noise minimization device 600 or the ambient
noise minimization device 600A is configured in the e-reader 100. The ambient noise
minimization device 600A includes a microphone 160, a reading mode determination unit 610, a
noise removal module 620, a speaker 150, a display control unit 630, and a display device 120.
The functions of the microphone 160, the reading mode determination unit 610, the noise
removal module 620 and the speaker 150 of the ambient noise minimization device 600A are
the same as those of the one shown in FIG.
[0067]
The display control unit 630 determines whether ambient noise 525 that matches the specific
sound pattern stored in advance is detected through the microphone 160. The specific sound
pattern is, for example, voice data such as a door chime, a ringing tone of a telephone, and a
voice calling the user's name, and any storage means 402, 408, 410, 412 of the computer
system constituting the e-reader 100. May be stored.
[0068]
When it is determined that the ambient noise 525 that matches the specific sound pattern is
detected, the display control unit 630 causes the display device 120 to display that the ambient
noise that matches the specific sound pattern is detected. This makes it possible to recognize that
ambient noise to be recognized by the user is generated.
[0069]
In the embodiment described above, the noise canceling sound wave 530 is output to the speaker
150. However, for example, the noise canceling sound wave 530 may be output to an earphone
or the like worn on the user's ear.
