Description
CHARACTER INPUT METHOD FOR ADDING VISUAL
EFFECT TO CHARACTER WHEN CHARACTER IS INPUT
AND MOBILE STATION THEREFOR
Technical Field
The present invention relates generally to a mobile station, and in particular, to a
character input method for adding various effects to a character displayed on a screen
when the character is input and a mobile station therefor.
Background Art
Recently, as mobile stations have become more popular, they have incorporated
additional functions so that users of the mobile stations can use the mobile stations for
these additional functions in addition to a phone communication function. Moreover,
in scope with the expansion of various services and additional functions, a mobile
terminal's display screen size and color palette has also increased Due to the users'
demands being more various and detailed than in the past, the screen space of the
mobile stations must now be used more efficiently using various methods. Ac-
cordingly, screen space should be used such that, various demands of the users are
satisfied and a user is not inconvenienced.
However, although current mobile stations can generate sound and images desired
by users using a download service, when a recipient's number is input or a short
message is edited, characters having the same font shape and/or size are typically used.
For example, a mobile station displays a number having a single font shape il-
lustrated in FIG. 1(A) when a user presses a key when dialing. The number having a
normal size or double size as the font size. When the user continues to dial, input
numbers fill a screen as illustrated in FIG. 1(B), and if the user continues to press more
keys, the input numbers are converted to a smaller font size and displayed as illustrated
in FIG. 1(C). When the user presses a "call" key, an image of trying to connect a call
to the input recipient's number is displayed as illustrated in FIG. 1(D).
FIG. 2 is a structural diagram illustrating a conventional dialing screen having a
layered structure. The conventional dialing screen includes a background layer 10 for
providing a single unicolor background image, a character input layer 20 for displaying
key-input data according to a key press, and an icon layer 30 for informing of a current
operation state according to the key press by displaying icons or images. That is, the
icon layer 30 displays icons of various shapes, such as a telephone shape representing a
conversation state and a speaker shape representing a sound setting item.

Best Mode for Carrying Out the Invention
Preferred embodiments of the present invention will be described herein below with
reference to the accompanying drawings. In the drawings, the same or similar elements
are denoted by the same reference numerals even though they are depicted in different
drawings. In the following description, well-known functions or constructions are not
described in detail since they would obscure the invention in unnecessary detail.
The present invention implements a function of displaying various character effects
on a character input screen of a mobile station by using a differentiated graphic
element according to a key input signal. To do this, a visual character theme set by a
user is displayed in a character input mode, and a character input effect corresponding
to the visual character theme is shown according to a key input signal. Accordingly,
since the mobile station can show a visual character input effect for every key input
sequence by allowing the user to select a desired visual character theme in advance, an
entertaining effect can be added to a user interface of the mobile station.
Components and operations of a mobile station having the function described above
will now be described with reference to FIG. 3 which is a block diagram of a mobile
station according to the present invention. Hereinafter, the character is the general term
for any sign which can be displayed on a screen, such as an English character, a
Korean character, a number, and a special character (e.g., "*", "!", etc).
Referring to FIG. 3, the mobile station includes a controller 100, a key input unit
110, a display unit 120, a memory 130, a radio frequency (RF) unit 140, and a sound
processing unit 150.
The controller 100 controls all operations of the mobile station, and particularly,
controls the display unit 120 to display a character input effect according to a preferred
embodiment of the present invention. Herein, the character input effect is displayed
differently according to a pre-set visual character theme, and if effect sound is included
in the visual character theme, the controller 100 controls the display unit 120 to display
the character input effect and simultaneously controls the sound processing unit 150 to
output the effect sound through a speaker every time a character is input.
As described above, when a character display on a screen is requested by inputting
a character, the controller 100 adds a visual effect corresponding to the pre-set visual
character theme to the input character and displays the visual-effect-added character on
a background image displayed according to the visual character theme. For example,
the character input effect can be displayed in all character input modes such as a
phone-call mode in which a user inputs a recipient's number to make a phone call and
a message edit mode in which a message is input and/or edited.
In another case, the controller 100 can display visual effect added characters even

when a display of characters received through a Short Message Service (SMS) or a
Multimedia Message Service (MMS) is requested. Herein, a message received from
another party's mobile station through the SMS or MMS can be processed by a cor-
responding message processing control unit included in the controller 100, i.e., an SMS
or MMS character processing unit. For example, when a message according to a visual
character theme is received, to display the message edited by the other party's mobile
station, a corresponding message processing control unit determines whether a cor-
responding visual character theme exists. If it is determined that the visual character
theme exists, the corresponding message processing control unit displays visual-
effect-added characters according to the visual character theme when the message is
displayed. Likewise, it is preferable that a display of visual characters to which a visual
effect according to a visual character theme is added be always applicable in all cases
where a character display is required besides in the character input modes.
The key input unit 110 provides an interface with the user, has various types of keys
such as various function keys, number keys (e.g., 0 to 9), and special keys (e.g., * and
#), and provides key input data corresponding to a key pressed by the user to the
controller 100. That is, the key input unit 110 generates key input data unique to each
key input signal and outputs the generated key input data to the controller 100. The
controller 100 detects which key corresponds to the key input data and performs a cor-
responding operation according to the detection result.
The control unit 100 controls the display unit 120 to receive display data cor-
responding to the key input data from the key input unit 110 and display the display
data, or display an operational state and a plurality of types of information of the
mobile station using icons and characters. In addition, when the user sets or operates a
needed function, the control unit 100 controls the display unit 120 to visually display a
state of the setting or operation so that the user is informed as required. Moreover, the
display unit 120 to which the present embodiment is applied displays a visual character
effect by which a visual effect is added to a character input by the user in the character
input mode.
The memory 130 is includes a ROM (Read Only Memory) and RAM (Random
Access Memory) for storing a plurality of programs and data. In particular, according
to a preferred embodiment of the present invention, the memory 130 stores data of a
display item for each layer according to a visual character theme. The memory 130
also stores a plurality of visual character themes and stores a visual character theme set
by the user as a default visual character theme.
The RF unit 140 is connected to the controller 100, converts sound data and control
data to an RF signal and transmits the RF signal, and receives an RF signal and
converts the received RF signal to sound data and control data.

The sound processing unit 150 is connected to the controller 100, converts sound
data input from the controller 100 to audible sound and outputs the audible sound
through the speaker 160, and converts a sound signal received through a microphone to
sound data and transmits the sound data to the controller 100. In addition, the sound
processing unit 150 to which the present embodiment is applied outputs effect sound
according to a corresponding visual character theme whenever a character input effect
according to a character input is displayed on the screen. For example, if a visual
character theme is "steel", a steel plate (not shown) is displayed as a background
image, and when a key is pressed, a character corresponding to the key can be
displayed on the steel plate as the character is carved on steel, and simultaneously, a
striking hammer effect sound can be output through the speaker.
A layered structure of a screen of a mobile station having the above-described con-
figuration on which a predetermined character input effect is displayed when a
character is input will now be described.
FIG. 4 is a schematic structural diagram of layers of a character input screen in a
mobile station according to the present invention. The character input screen of the
mobile station according to the present invention basically includes a background layer
200 for displaying a background image according to a visual character theme and a
character input layer 220 for displaying an input character by not changing a font of
the character but adding a visual effect to the character, and further includes a character
effect layer 210 for displaying a pre-defined specific visual effect on a background
portion on which the input character is displayed or on the entire screen in order to add
a visual effect to the input character and an icon layer 230 for displaying images of
various input tools when the character is input. Herein, the visual effect is usually
overlapped on the background image of the visual character theme provided by the
background layer 200, so that the character can be visually distinguished from the
character effect. In addition, an icon indicating an input device provided by the icon
layer 230 is overlapped on the background image of the visual character theme, as well
as the character and the character effect.
In more detail, the background layer 200 displays the background image of the
visual character theme using the entire screen (or a substantial portion thereof) of the
mobile station. According to a preferred embodiment of the present invention, the
character effect layer 210 can display various effects, such as a wave effect or a flame
effect, around a location of a displayed cursor or at which characters are being
displayed. For example, when the background image of the visual character theme is a
lake, a character is displayed by the character input layer 220 on the lake background
image provided by the background layer 200, and then the character effect layer 210
can give such an effect that tiny waves rise below a current cursor, below displayed

characters, and/or all over the screen. By doing this, a character is displayed on water
in what appears to be three dimensions. Additionally, an effect of tiny waves rising and
falling can be provided when a character is input.
To add a visual effect to a character corresponding to each key input signal, the
character input layer 220 displays the character using various graphic elements and
various fonts, such as an ink pen font, a light bulb font, a Post-it™ font, and a twinkle
font. The icon layer 230 displays an ink-pen image as an input tool image when a
visual effect added character, for instance, having the ink-pen font, is displayed by
overlapping the background image (e.g., letter paper image) of the visual character
theme. For example, when the visual effect added character is displayed, the icon layer
230 displays an image indicating an input tool tracing strokes of the character in order
to give a feeling of writing the character for a user. While the character strokes are
being drawn according to a drawing sequence, the image indicating the input tool si-
multaneously moves to trace the character strokes, and when the character is fully
drawn, the image indicating the input tool is displayed at the ending point of the
character strokes. Additionally, an optional scratching sound (e.g., a sound similar to a
quill scratching paper as it draws a character can be played by the speaker as the
character is drawn.
The character input screen is provided to the user as illustrated in FIG. 5, and a
character input effect corresponding to each visual character theme is displayed when
the user inputs a character. According to a preferred embodiment of the present
invention, visual character themes having various character input effects, such as an
ink pen theme illustrated in FIG. 5(A), an LED panel theme illustrated in FIG. 5(B), a
twinkle theme illustrated in FIG. 5(C), a Post-it™ theme illustrated in FIG. 5(D), a
steel theme illustrated in FIG. 5(E), and a blackboard theme (not shown), can be used.
While FIG. 5 illustrates the ink pen, LED panel, twinkle, Post-it™, and steel themes
according to a preferred embodiment of the present invention, the present invention is
not limited to this. That is, visual character themes having various character input
effects can be displayed according to a selection of the user, a service provider, or a
mobile station manufacturer. In addition, the character input effects according to a
preferred embodiment of the present invention can be created by the user, or received
by a content provider as a kind of content and modified according to a selection of the
user.
There are various methods of displaying a visual-effect-added character on the
character input layer 220 according to the present invention. Three of these methods
will now be described below.
The first method of displaying a visual-effect-added-character is known as an
animated pen input method in which a character is drawn to trace strokes of the

character corresponding to a key input signal as writing the character for the user when
a key is pressed, i.e., a method of inputting a character by adding an animation effect
thereto. In this method, animated pen input data of each input character is stored in the
mobile station, a corresponding visual character theme is set, and then if a certain
character is input to the character input screen, animated pen input data corresponding
to the input character is displayed. Although a method of storing and displaying
animated pen input data of each input character is illustrated, it is also possible to set
an animated pen effect and move an animated pen to trace an input character by adding
drawing sequence information of the input character to the animated pen effect. When
this animated pen effect is used, the animated pen input method can be used not only
when a simple number key is pressed but also when a character having a high degree
of freedom, such as a drawing input through a touch screen or a separate input tool, is
input.
To describe in more detail the animated pen input method, reference will be made
to FIG. 5(A), which illustrates the ink pen theme as a visual character theme. This
method is achieved by allocating a drawing sequence of a corresponding character to
each key in advance. For example, when a number key is pressed for dialing, the
controller 100 of the mobile station obtains a drawing sequence allocated in advance to
correspond to the input number and draws character strokes of the input number
according to the drawing sequence. When a character other than a number is input,
strokes of the input character are also drawn according to a drawing sequence of the
character, thereby being displayed on the screen. Besides, for the LED panel theme il-
lustrated in FIG. 5(B), when a character key is pressed, a character corresponding to
the character key is displayed in a form of illuminating LEDs according to a drawing
sequence of the character. As another example, for the twinkle theme illustrated in
FIG. 5(C), when a character key is pressed, a character corresponding to the character
key is displayed in a form of sequentially flashing starlight on a universe background
image according to a drawing sequence of the character.
The second method of displaying a visual-effect-added-character is known as a
collage method of displaying a character by loading a stored character image cor-
responding to a key input signal when a key is pressed. For example, referring to the
Post-it™ theme illustrated in FIG. 5(D), when a number key is pressed, a number
image having a Post-it™ form corresponding to the number key is loaded and
displayed. That is, character images are loaded and displayed one-by-one when keys
are pressed in a feeling of attaching "Post-it™" on a cork wall or other background.
The third method of displaying a visual-effect-added-character is known as a relief
method of displaying a character as embossing or intaglioing the character when a key
is pressed. For example, referring to the steel theme illustrated in FIG. 5(E), when a

number key is pressed, a number corresponding to the number key is displayed as
being raised in relief on a steel plate. Likewise, effects according to each visual
character theme can be variously provided.
A process of setting one of visual character themes displayed variously as described
above will now be described with reference to FIG. 6 which is a flowchart illustrating a
process of setting a visual character theme according to the present invention.
Referring to FIG. 6, the controller 100 determines in step 600 whether a request to
change a visual character theme is input by a user. The request can be achieved by the
user selecting a visual character theme change menu from a main menu. As a result of
the determination in step 600, if a request to change a visual character theme is input,
the controller 100 displays a default visual character theme in step 610. In step 620, the
controller 100 determines whether a left or right direction key is pressed. That is, for
the user's convenience, the user can see another visual character theme using the
direction key in the present embodiment. As a result of the determination in step 620,
if the left or right direction key is pressed, the controller 100 rotationally displays
another visual character theme in a left or right direction according to the key input
signal in step 630. In step 640, the controller 100 determines whether one of a plurality
of visual character themes is selected by the user. As a result determined in step 640, if
a certain visual character theme is selected, the controller 100 stores the selected visual
character theme as the default visual character theme in step 650. Thereafter, the user
can use a desired visual character theme.
A process of displaying the visual character theme selected as described above will
now be described with reference to FIG. 7 which is is a flowchart illustrating a process
of adding a visual effect to character using a layered structure of a character input
screen according to the present invention.
Referring to FIG. 7, if a character input mode is selected by the user in step 700, in
step 710, the controller 100 loads a stored default visual character theme and sets the
character input screen using the default visual theme. That is, the controller 100
displays a background image corresponding to the default visual character theme on
the character input screen through the background layer 200. Herein, if the default
visual character theme is achieved in a manner of writing a character for the user, an
input tool image is displayed through the icon layer 230 (e.g., a corresponding anim
ated pen is displayed on the background image). In step 720, the controller 100
determines whether a character key is pressed. Herein, the character key is a key for
inputting any sign which can be displayed on a screen, such as an English character, a
Korean character, a number, and a special character.
If a character key is pressed, the controller 100 displays a character input effect
according to the default visual character theme in response to a key input signal cor-

responding to the character key in step 730. In more detail, when the key input unit
110, for instance, senses that the user presses the character key and transmits key input
data to the controller 100, the controller 100 adds a visual-effect-corresponding to the
default visual character theme to an input character according to the key input data.
Then, the controller 100 displays the visual-effect-added character on the background
image displayed according to the default visual character theme. In step 740, the
controller 100 determines whether another key is pressed within a predetermined time,
i.e. whether a character key is further pressed. As a result of the determination in step
740, if another a character or key is pressed, the controller proceeds to step 730 and
displays an input-visual-effect-added character on the background image according to
the default visual character theme by following the displayed character.
A detailed example using the present invention will now be described with
reference to FIGs. 8 and 9.
FIG. 8 is a flowchart illustrating a method of providing a character input effect
according to the present invention, and FIG. 9 illustrates screen shots showing the
character input effect according to the present invention.
Although an example will now be described by illustrating FIGs. 8 and 9, the
method of providing a character input effect according to a preferred embodiment of
the present invention should not be construed as limited to the embodiment shown in
FIGs. 8 and 9.
Referring to FIGs. 8 and 9, if a phone call mode is selected in step 800 by the user
in the layered screen structure illustrated in FIG. 4, the controller 100 sets a character
input screen using a stored visual character theme in step 805. That is, a background
image corresponding to the default visual character theme is displayed through the
background layer 200. Herein, if the default visual character theme is a light bulb
theme, an LED panel background image is displayed through the background layer
200. In step 810, the controller 100 determines whether a key for dialing is pressed. As
a result in the determination in step 810, if a key for dialing is pressed, the controller
100 displays a pre-defined character input effect on the background image in response
to a key input signal corresponding to the key in step 815. For example, an effect of il-
luminating light bulbs as illustrated in FIG. 9A is displayed. Herein, the effect can be
achieved by sequentially illuminating the light bulbs displayed on the LED panel
background image according to a drawing sequence of a character corresponding to the
key or illuminating the light bulbs at once.
In step 820, the controller 100 determines whether another key is pressed within a
predetermined time. As a result of the determination in step 820, if another key is
pressed, the controller 100 determines in step 825 whether the number of characters
which can be displayed on the screen is exceeded. As a result of the determination in

step 825, if a character corresponding to the key can be displayed on the screen, the
controller 100, by proceeding back to step 815, adds the character input effect to the
character and displays the character on the screen next to the previously displayed
character. While repeating the above-described procedures in the same manner
according to subsequently pressed keys, the controller 100 determines in step 825
whether the number of characters which can be displayed on the screen is exceeded.
As a result of the determination in step 825, if the number of characters which can be
displayed on the screen is exceeded, i.e., if the screen is filled up by input characters as
illustrated in FIG. 9B, the controller 100 changes a current image to an image having a
smaller sized font as illustrated in FIG. 9(D) in step 830. Herein, to present a visually
pleasing effect when the images are changed, the controller 100 may display a zoom-
out image for temporarily displaying a flash on the LED panel background image as il-
lustrated in FIG. 9(C).
In a state where a recipient's number is input as illustrated in FIG. 9(D), the
controller 100 determines in step 835 whether a call connection key for trying to make
a phone call with the recipient's number is pressed. As a result of the determination in
step 835, if the call connection key is pressed, the controller 100 displays a calling
image according to a visual character theme illustrated in FIG. 9(F) in step 840.
Herein, when the recipient's number input image is changed to the calling image, the
controller 100 may also display a zoom-out image illustrated in FIG. 9(E).
While the invention has been shown and described with reference to a certain
preferred embodiment thereof, it will be understood by those skilled in the art that
various changes in form and details may be made therein without departing from the
spirit and scope of the invention. For example, while a visual character effect has been
described only for a character input mode and a message receiving mode, the visual
character effect can be applied to various modes in which a visual character can be
displayed. Therefore, the spirit and scope of the invention will be defined by the
appended claims and the equivalent not by the described preferred embodiments.
