Title of Invention: INFORMATION PROCESSING DEVICE, IN¬
FORMATION PROCESSING METHOD, AND PROGRAM
Technical Field
[0001] The present disclosure relates to an information processing device, an information
processing method, and a program.
Background Art
[0002] In recent years, the amount of information that users deal with has increased along
with the development of information processing technologies. For at least this reason,
questions of how information necessary for users will be extracted and how in
formation will be presented to users have become greater matters of interest.
[0003] As an information presentation method, a presentation method using a screen display
has been widely used. There have been proposed methods of presenting information
using a screen display in accordance with changes in a device that a user uses and
changes in information to be provided. However, there have been limitations even on
presenting information using a screen display. Thus, a method of presenting in
formation using sound has been proposed.
[0004] Japanese Patent Application Publication No. 2008-151766A, for example, discloses a
method of outputting sound data having directivity based on the distance and direction
from a current position of a device to a position that is set in advance. With the device,
direction indication can be performed using only the auditory sense.

Summary
Technical Problem
[0006] It is still desirable to provide a way of presenting information more usefully to a user.
Therefore, the present disclosure proposes generation of localization information of a
notification sound that informs of notification information that is associated with in
formation other than a screen currently displayed, as an example of a case in which in
formation is provided using a sound.
Solution to Problem
[0007] According to an embodiment of the present disclosure, there is provided an in
formation processing apparatus including a display control unit configured to initiate a
selective displaying of content screens, and a sound output control unit configured to
generate localization information of a notification sound associated with a first content
screen that is not currently being displayed and initiate an outputting of the notification
sound to a user in accordance with the localization information while a second content
screen is being displayed.
[0008] According to such a configuration, the first content screen may not be displayed
when the sound output control unit initiates the outputting of the notification sound.
Furthermore, the sound output control unit may further be configured to initiate an
outputting of the notification sound with a directivity that conveys to the user an
operation direction for enabling a changing of current displaying from the second
content screen to the first content screen.
[0009] Further, according to an embodiment of the present disclosure, there is provided an
information processing apparatus including a display unit configured to selectively
display content screens thereon, a sound output control unit configured to generate lo
calization information of a notification sound associated with a first content screen that
is not currently displayed by the display unit, and a sound output unit configured to
output the notification sound to a user in accordance with the localization information
while the display unit displays a second content screen thereon.
[0010] Still further, according to an embodiment of the present disclosure, there is provided
an information processing method including generating localization information of a
notification sound associated with a first content screen that is not currently displayed,
and outputting, while a second content screen is being displayed to a user, the noti
fication sound to the user in accordance with the localization information.
[001 1] According to an embodiment of the present disclosure, there is provided a nontransitory
computer-readable medium embodied with a program, which when executed
by a computer, causes the computer to perform a method including generating lo
calization information of a notification sound associated with a first content screen that
is not currently displayed, and outputting, while a second content screen is being
displayed to a user, the notification sound to the user in accordance with the lo
calization information.
[0012] According to an embodiment of the present disclosure, there is provided an in
formation processing device including an operation direction acquisition unit that
acquires, from a first screen, an operation direction from which a second screen a s
sociated with a notification sound is displayed, and a localization information
generation unit that generates localization information indicating a sound source
position of the notification sound according to the operation direction.
[0013] According to such a configuration, the localization information of the notification
sound according to the operation direction from which the second screen associated
with the notification sound is displayed may be generated. Thus, a user who heard the
notification sound output in accordance with the localization information can recognize
the operation direction from which the second screen is displayed.
[0014] Further, according to an embodiment of the present disclosure, there is provided an
information processing method including acquiring, from a first screen, an operation
direction from which a second screen associated with a notification sound is displayed,
and generating localization information indicating a sound source position of the noti
fication sound according to the operation direction.
[0015] Further, according to an embodiment of the present disclosure, there is provided a
program that causes a computer to function as an information processing device
including an operation direction acquisition unit that acquires, from a first screen, an
operation direction from which a second screen associated with a notification sound is
displayed, and a localization information generation unit that generates localization in
formation indicating a sound source position of the notification sound according to the
operation direction.
Effects of disclosure
[0016] According to the present disclosure as described above, it is possible to effectively
convey information to a user by generating localization information of a notification
sound that informs of notification information that is associated with information other
than a screen currently displayed.

Description of Embodiments
[0018] Hereinafter, embodiments of the present disclosure will be described in detail with
reference to the appended drawings. Note that, in this specification and the appended
drawings, structural elements that have substantially the same function and structure
are denoted with the same reference numerals, and repeated explanation of these
structural elements is omitted.

8. Hardware Configuration Example
[0020] <1. Overview>
First, the overview of the technology proposed in the present disclosure will be
described with reference to FIGS. 1, 14, and 15. FIG. 1 is an illustrative diagram
showing the overview of functions mounted in an information processing device
according to an embodiment of the present disclosure. FIG. 14 is an illustrative
diagram showing an example of an alert notification method in the related art. FIG. 15
is an illustrative diagram showing another example of the alert notification method in
the related art.
[0021] As smartphones become more widely distributed, customizing functions of in
formation processing devices for users by downloading applications is becoming more
common. In addition, devices for multi-tasking-compliant have been widely dis
tributed, and a plurality of functions can be activated at the same time. However, a
display area of a display is physically limited. For these reasons, the display area may
be shifted by scrolling or performing a shifting operation of a screen.
[0022] Various methods of informing a user of notification information that is generated, for
example, by an application owing to a certain cause have been proposed. As illustrated
in FIG. 14, for example, mostly on the home screen of a smartphone, icons of ap
plications are arranged. On such a home screen, it is possible to inform the user of the
presence of notification information and the number of notification information pieces
by numbering the pieces of notification information on the icon of an application that
has information to be notified of.
[0023] In addition, FIG. 15 illustrates an example of a method of informing a user of noti
fication information when the notification information is generated elsewhere than the
screen currently displayed. According to the method of FIG. 15, a pop-up window W
that includes the notification information may be displayed on the screen being
displayed. The pop-up window W may include, for example, a button that receives an
action for the notification information. The user may be able to ascertain details of the
notification information by operating the button.
[0024] In the method illustrated in FIG. 15, however, the user should suspend the operation
being performed. Moreover, there is a case in which a process executed in the
background is halted. In consideration of the operability by the user, such a halt of an
operation that a user desires is not favorable. Therefore, the present disclosure
proposes a method of providing a user with notification information without halting an
operation that the user desires, by using a sound.
[0025] As illustrated in FIG. 1, for example, the present disclosure provides a user with noti
fication information using a sound having directivity. Herein, when an application of
an icon set on the screen on the right side of the screen that is currently displayed has
notification information, a notification sound may be set to be heard from the right
side. With this configuration, the user can ascertain the direction of an operation for
acquiring the notification information based on the direction of the notification sound.
Hereinbelow, an information processing device for realizing the function will be
described.
[0026] <2. Functional Configuration>
Herein, a functional configuration of the information processing device 10 according
to an embodiment of the present disclosure will be described with reference to FIG. 2.
FIG. 2 is a block diagram illustrating the functional configuration of the information
processing device according to an embodiment of the present disclosure.
[0027] The information processing device 10 may be an information processing device
including, for example, a mobile telephone including a smartphone, a PHS (Personal
Handyphone system), a portable music reproduction device, a portable video
processing device, a portable game device, an imaging device, a navigation system, a
PC (Personal Computer), a home video processing device (a DVD recorder, a video
deck, or the like), a home game device, a home appliance, and the like.
[0028] The information processing device 10 may include mainly an operation unit 105, an
operation information acquisition unit 110, a display unit 115, a display control unit
120, a sound output unit 125, and a sound output control unit 130.
[0029] (Operation Unit 105)
The operation unit 105 may have a function of generating an input signal for
performing an operation that a user desires. The operation unit 105 may include, for
example, an input section such as a touch panel, a mouse, a keyboard, a button, a mi
crophone, a switch, a lever, and various sensors that are used to input information by a
user, an input control circuit that generates and outputs input signals based on an input
by a user, or the like. For example, the operation unit 105 can generate and output an
input signal based on an operation by detecting the operation that a user performs on a
touch panel. In addition, the operation unit 105 can generate and output input signals
based on tilt information of the housing of the information processing device 10
acquired by a tilt sensor.
[0030] (Operation Information Acquisition Unit 110)
The operation information acquisition unit 110 may have a function of acquiring
operation information input by a user. For example, the operation information ac
quisition unit 110 can acquire input signals output from the operation unit 105 as
operation information. The information processing device 10 can operate based on the
operation information acquired by the operation information acquisition unit 110. Note
that the operation information acquisition unit 110 is an example of an operation
direction acquisition unit that acquires, from a first screen, an operation direction from
which a second screen associated with a notification sound is displayed.
[0031] (Display Unit 115)
The display unit 115 is an example of an output device, and may be a display device
such as a liquid crystal display (LCD) device, or an organic EL (or OLED: Organic
Light Emitting Diode) display device. The display unit 115 can operate according to
the control of the display control unit 120.
[0032] (Display Control Unit 120)
The display control unit 120 may have a function of controlling the content of a
display screen to be provided to a user. In addition, the display control unit 120 can
control the content of the display screen based on operation information acquired by
the operation information acquisition unit 110. For example, the display control unit
120 can cause the display screen to be scrolled according to a scroll operation
performed by a user. In addition, the display control unit 120 can cause the display
screen to be enlarged, reduced, or undergo screen shifting according to the operation
information. Further, the display control unit 120 is an example of a generation unit
that may generate a screen relating to notification information when the generation of
the notification information is detected. In an e-mail application, for example, when
notification information that informs of the reception of a new e-mail is generated, the
display control unit 120 can cause a notification screen that notifies of the new e-mail
to be activated so as to arrange the notification screen to be displayed if a user
performs a scroll operation from a screen currently displayed. Note that the notification
screen in this case may be a text display screen containing the text of the e-mail, or a
list screen of received e-mails. In addition, as will be described below, the display
control unit 120 may be an example of a guidance information display control unit that
causes guidance information indicating an operation direction from which a screen a s
sociated with the notification information is displayed to be displayed. Further, the
display control unit 120 is an example of a generation unit that generates a second
screen associated with notification information when the generation of the notification
information is detected.
[0033] (Sound Output Unit 125)
The sound output unit 125 may have a function of outputting a sound signal. The
sound output unit 125 may be, for example, a speaker. In addition, the sound output
unit 125 may be an output terminal that outputs a sound signal to a sound output
device such as headphones. The sound output unit 125 can operate according to the
control of the sound output control unit 130. Note that the sound output device used
here can output stereophony according to localization information of a sound.
[0034] (Sound Output Control Unit 130)
The sound output control unit 130 may have a function of outputting a sound to a
user. In addition, the sound output control unit 130 is an example of a localization in
formation generation unit that may generate localization information indicating a
sound source position. The sound output control unit 130 can generate localization information
indicating a sound source position of a notification sound from the first
screen according to an operation direction from which the second screen associated
with the notification sound is displayed. In such a case, the sound output control unit
130 can generate the localization information according to the distance between the
first screen and the second screen. The first screen may be, for example, a screen
currently displayed. The distance between the first screen and the second screen may
change every time the screen currently displayed is changed. For this reason, the sound
output control unit 130 can update the localization information every time a change is
made in the screen currently displayed. The sound output control unit 130 can control
the output of a sound so that the volume increases as the sound source position
becomes closer.
[0035] The sound output control unit 130 may cause the sound source position of the noti
fication sound to be merely fixedly positioned in a direction according to an operation
direction from which a screen associated with the notification sound is displayed. In
addition, humans tend to more easily perceive the direction of a sound of which the
sound source position changes than that of a sound from a merely fixed position. For
this reason, after the sound source position of the notification sound is changed, for
example, the sound output control unit 130 may set the arrival point to be a direction
according to an operation direction from which a screen associated with the noti
fication sound is displayed. In a screen currently displayed, for example, when the
screen associated with the notification sound is displayed according to a scroll
operation from the right side to the left side, the sound output control unit 130 may
generate localization information in which the sound source position of the notification
sound is fixed to the right side of the user. In addition, in such a case, after the sound
source position of the notification sound is changed, the sound output control unit 130
may generate localization information so as to be fixed on the left side of the user.
[0036] In addition, when the orientation of the display screen is changed according to the tilt
of the information processing device 10, the sound output control unit 130 may change
the sound source position of the notification sound according to changes in the ori
entation of the display screen. The sound output control unit 130 may be an example of
an acoustic processing unit that implements a stereophonic process for a notification
sound.
[0037] The localization information generated by the sound output control unit 130 will be
described in more detail later by exemplifying a plurality of scenes. Note that the noti
fication sound herein may be a notification sound that informs of, for example, the
reception of an e-mail, but is not limited thereto. When shifting is performed from a r e
production screen used when a moving image is reproduced to a list screen of moving
images, the sound of the moving image may be used as a notification sound for
notifying of the direction of the shifting. In this case, the sound of the moving image
may also belong to a notification sound.
[0038] Hereinabove, examples of the functions of the information processing device 10
according to embodiments are shown. Respective constituent elements described above
may be configured using general-purpose members or circuits or may be configured
using hardware specialized for the functions of the respective constituent elements. In
addition, the functions of the respective constituent elements may be fulfilled by
reading a control program from a storage medium such as a ROM (Read Only
Memory) or a RAM (Random Access Memory) storing the control program describing
procedures in which an arithmetic operation unit such as a CPU (Central Processing
Unit) realizes the functions and by interpreting the program. Thus, it is possible to ap
propriately change a configuration to be used according to the level of the technology
at a time when the present embodiment is implemented.
[0039] A computer program for realizing each of the functions of the information processing
device 10 according to embodiments as described above can be created and installed in
a personal computer, or the like. In addition, a recording medium that stores such a
computer program and which is readable on the computer can also be provided. The
recording medium may include, for example, a magnetic disk, an optical disc, a
magneto optical disc, a flash memory, and the like. In addition, the computer program
may be delivered through, for example, the Internet, without using the recording
medium.
[0040] <3. Notification Operation>
Next, a notification operation of the information processing device according to an
embodiment of the present disclosure will be described with reference to FIG. 3. FIG.
3 is a flowchart for describing a notification operation of the information processing
device according to an embodiment of the present disclosure.
[0041] First, the information processing device 10 may determine whether there is noti
fication information or not (SlOO). When a setting is made to give notification to a user
by detecting any cause by an application operated inside the information processing
device 10, for example, the information processing device 10 can determine whether
there is notification information or not based on whether the cause of notification has
been detected or not.
[0042] When it is determined that there is notification information in the determination of
Step SlOO, the sound output control unit 130 may generate localization information of
a notification sound that informs of the notification information (S105). Then, the
sound output control unit 130 outputs the notification sound based on the generated lo
calization information (S107).
[0043] Next, the display control unit 120 may determine whether there is a change in a
display screen (SI 10). When it is determined here that there is a change in the display
screen, the sound output control unit 130 may update the localization information
(SI 15). On the other hand, when it is determined that there is no change in the display
screen in the determination of Step SI 10, the process of Step SI 15 may be omitted.
[0044] Next, the sound output control unit 130 may determine whether a predetermined time
has elapsed or not (S120). The predetermined time used here may be a time decided in
advance as a time taken to output the notification sound. The predetermined time may
have, for example, a value set in advance in the information processing device 10 by
the user. Alternatively, the predetermined time may have a value set in advance as a
predetermined value of an application.
[0045] When it is determined that the predetermined time has elapsed in the determination
of Step S120, the sound output control unit 130 may stop output of the notification
sound (S125), and may repeat the process from Step S100. On the other hand, when it
is determined that the predetermined time has not elapsed in the determination of Step
S120, the process may return to Step SI 10, and the notification sound may be output
while updating of the localization information is repeated until the predetermined time
elapses.
[0046] As described above, the notification sound that informs of the notification in
formation may be output as a sound signal having directivity based on the positional
relationship between a screen associated with the notification information and a screen
currently displayed. With this configuration, the user can instantly know the operation
direction from which the screen associated with the notification information is
displayed from the direction in which the notification sound is heard. Hereinbelow, the
notification operation of the information processing device 10 will be described by ex
emplifying a plurality of specific scenes.
[0047] <4. First Notification Example (Notification from an Application on a Home
Screen)>
Next, a first notification example of the information processing device according to
an embodiment of the present disclosure will be described with reference to FIGS. 4
and 5. FIG. 4 is an illustrative diagram illustrating the first notification example of the
information processing device according to an embodiment of the present disclosure.
FIG. 5 is an illustrative diagram illustrating a state in which a scroll operation is
performed in the first notification example of the information processing device
according to an embodiment of the present disclosure.
[0048] For example, a case in which a home screen includes four screens of a screen SCI, a
screen SC2, a screen SC3, and a screen SC4 displayed according to scroll operations
will be considered. When the screen SC2 among the four screens is displayed as i l
lustrated in FIG. 4 and the generation of notification information of an application
indicated by an icon 30 displayed on the screen SC4 is detected, the sound output
control unit 130 may generate localization information of a notification sound that
informs of the notification information based on an operation direction from which the
screen SC4 is displayed from the screen SC2 currently displayed. In this case, the
sound output control unit 130 can generate the localization information so that the noti
fication sound is heard from the right side.
[0049] In addition, when an operation of changing the display state of the screen currently
displayed is detected, the sound output control unit 130 can update the localization in
formation according to the operation. Assuming that a scroll operation is performed
from the right to the left side in the state shown in FIG. 4, for example, and the screen
SC3 comes to serve as the screen currently displayed as illustrated in FIG. 5. At this
moment, the sound output control unit 130 can generate the localization information
based on an operation direction from which the screen SC4 associated with notification
information is displayed from the screen SC3 currently displayed and the distance
between the screen SC3 and the screen SC4. In this case, it may be desirable to set
control so that the notification sound is heard louder in the state shown in FIG. 5 than
in the state shown in FIG. 4. With this configuration, the user can know the operation
direction from which the screen SC4 associated with the notification sound is
displayed based on the direction in which the notification sound is heard. In addition,
the user can perceive the distance from the screen currently displayed to the screen a s
sociated with the notification sound from the volume of the notification sound.
[0050] <5. Second Notification Example (Notification of a Screen Shifting Direction)>
Next, a second notification example of the information processing device according
to an embodiment of the present disclosure will be described with reference to FIG. 6.
FIG. 6 is an illustrative diagram illustrating the second notification example of the in
formation processing device according to an embodiment of the present disclosure.
[0051] Herein, a case is illustrated in which, when a moving image is reproduced, a screen is
shifted to the lateral direction after a "return" button is pressed. In this case, the sound
output control unit 130 can provide an animation of a sound by changing a sound
source position in accordance with the shifting of the screen. At this moment, the user
hears the notification sound as if the sound were fading away to the right side while the
screen for reproducing the moving image is shifted to the right side. Accordingly, the
positional relationship between the direction in which the screen for the reproduction is
shifted and the return button can be indicated to the user. In this case, for example, a
sound of the moving image may be used as the notification sound. Alternatively,
another alarm sound may be used as the notification sound.
[0052] <6. Third Notification Example (Notification of Completion of Buffering)>
Next, a third notification example of the information processing device according to
an embodiment of the present disclosure will be described with reference to FIG. 7.
FIG. 7 is an illustrative diagram illustrating the third notification example of the in
formation processing device according to an embodiment of the present disclosure.
[0053] An animation of a notification sound may be used to notify of the completion of
buffering in reproduction of a moving image. As illustrated in FIG. 7, for example, a
case is considered in which, in a moving image reproduction screen SC21, the moving
image is in the state of being no longer reproduced due to buffering of the moving
image. At this moment, when a user causes a moving image list screen SC22 to be
displayed by pressing the "return" button, performing a scroll operation, or the like, the
user can operate the moving image list screen SC22. Then, when the moving image is
in the state of being reproduced after the buffering, the sound output control unit 130
can output a notification sound as if the notification sound were heard from the
direction in which the moving image reproduction screen SC 2 1 is shifted. Herein, the
sound output control unit 130 can control the output of the notification sound so that
the notification sound is heard from the right side. The notification sound used here
may be an alert sound or a sound of the moving image reproduced on the moving
image reproduction screen SC21.
[0054] Accordingly, the user can grasp the completion of the buffering. In addition, when
shifting can be performed between the moving image reproduction screen SC 2 1 and
the moving image list screen SC22 using a scroll operation, the user can grasp (recall)
the direction of the scroll operation.
[0055] <7. Fourth Notification Example (Generation of an Activation Screen of an Ap
plication Having Notification Information)>
Next, a fourth notification example of the information processing device according to
an embodiment of the present disclosure will be described with reference to FIGS. 8 to
12. FIG. 8 is an illustrative diagram illustrating generation of a notification screen in
the fourth notification example of the information processing device according to an
embodiment of the present disclosure. FIG. 9 is an illustrative diagram illustrating an
operation for the notification screen shown in FIG. 8. FIG. 10 is an illustrative diagram
illustrating a restriction on a generation position of the notification screen in the fourth
notification example of the information processing device according to an embodiment
of the present disclosure. FIG. 11 is an illustrative diagram illustrating an operation for
the notification screen shown in FIG. 10. FIG. 12 is an illustrative diagram illustrating
a modified example in which guidance information is displayed together with a noti
fication sound in the fourth notification example of the information processing device
according to an embodiment of the present disclosure.
[0056] The first to third notification examples described above are examples of alert noti
fication from a screen that is activated from the beginning. Herein, an example of notification
from an application that is not activated will be considered. When there is a
notification from an application that is not activated, a user can ascertain information
relating to the notification with a few operations by activating and automatically
arranging a screen relating to the notification. At this moment, the untimely display of
the notification as well as the screen relating thereto may disturb user operation. Thus,
herein, screens may be arranged in such a way that a screen that is activated by a onestep
operation (for example, a scroll operation in any direction) may be displayed from
a screen currently displayed.
[0057] Herein, the user may not be able to perceive in which direction an operation should
be performed on the screen that is automatically arranged. Thus, according to the
present disclosure, the user may be able to instantly perceive the operation direction
based on the output of a notification sound that informs the direction of automatic ar
rangement.
[0058] As illustrated in FIG. 8, a moving image reproduction screen m displayed in a state 1.
When the reception of an e-mail occurs here as notification information, the display
control unit 120 may arrange an e-mail display screen on any of the upper, lower, right,
and left sides of the moving image reproduction screen as shown in a state 2. At this
moment, the sound output control unit 130 can control an output of a notification
sound having directivity from the arranged screen. Note that, herein, states 2A, 2B, 2C,
and 2D are collectively referred to as the state 2 without discrimination. The same is
applied hereinbelow. In the state 2A, for example, the e-mail display screen is arranged
on the right side of the screen currently displayed. At this moment, the user hears the
notification sound from the right side. In addition, in the state 2B, the e-mail display
screen is arranged on the left side of the screen currently displayed. At this moment,
the user hears the notification sound from the left side. In addition, in the state 2C, the
e-mail display screen is arranged on the lower side of the screen currently displayed.
At this moment, the user hears the notification sound from the lower or back side. In
addition, in the state 2D, the e-mail display screen is arranged on the upper side of the
screen currently displayed. At this moment, the user hears the notification sound from
the upper or front side. Herein, the arranged screen may be set to be a display screen
containing text of the e-mail, but the present technology is not limited to the example.
A screen relating to notification may be, for example, an e-mail list screen.
[0059] In addition, as illustrated in FIG. 9, when a scroll operation is performed from the
screen of the state 2, the e-mail display screen may be displayed on the display unit
115 as shown in a state 3. In this manner, notification information can be ascertained
with a one-step operation by automatically arranging a screen relating to notification.
At this moment, by arranging the sound source position of the notification sound
according to the operation direction from which the screen relating to the notification
is displayed, the user can perceive the position in which the screen relating to the noti
fication is arranged and the operation direction from which the screen is displayed
from the directions of the notification sound.
[0060] Further, the display control unit 120 can restrict the position in which the screen
relating to the notification is arranged. For example, the display control unit 120 may
restrict the position in which the screen relating to the notification based on an
operation direction that can be accepted by a screen that has been being displayed
when notification information is generated. Referring to FIG. 10, for example, a case is
considered in which a screen displayed in a state 11 is a screen on which a scroll
operation can be performed in the upper-lower direction of the screen.
[0061] In this case, when the display control unit 120 arranges the e-mail display screen so
as to be displayed by a scroll operation in the upper-lower direction, the user may unin
tentionally cause the e-mail display screen to be displayed. In other words, it may be
difficult for the user to discriminate whether the scroll operation in the upper-lower
direction is a scroll operation set in the moving image reproduction screen that has
been displayed in the state 11 or a scroll operation for displaying the e-mail display
screen. Thus, the display control unit 120 can arrange the e-mail display screen so that
the e-mail display screen is displayed by an operation performed in the direction or
thogonal to the upper-lower direction that is the operation direction accepted in the
moving image reproduction screen (state 12).
[0062] As illustrated in FIG. 11, also on the screen displayed in the state 12, it is possible to
display the e-mail display screen in such a way that the user determines the operation
direction from the direction in which the notification sound is heard and performs a
scroll operation (state 13).
[0063] In addition, the operation direction from which notification information is displayed
may be provided to the user by displaying guidance information 50 that guides a scroll
operation in a predetermined direction in addition to the notification sound. As i l
lustrated in FIG. 12, for example, it is assumed that the user has operated a map ap
plication in a state 21. In this case, when notification information of e-mail reception is
generated, the display control unit 120 may arrange the e-mail display screen on the
left side of the screen currently displayed (state 22). At this moment, the sound output
control unit 130 may set the sound source position of the notification sound to be the
left side thereof. In addition, the display control unit 120 can cause the guidance in
formation 50 to be further displayed over the display screen in a superimposing
manner. The guidance information 50 may be, for example, an arrow indicating the
operation direction from which the e-mail display screen is displayed as illustrated in
FIG. 12. When the user performs a scroll operation in the direction indicated by the
guidance information 50, the e-mail display screen may be displayed (state 24).
