Mobile Phone Patent Description
FIELD OF THE INVENTION
The present invention relates to handwriting script input of the
mobile phones, and particular to a method for inputting and permuting
original scripts to an external mobile phone and the device for
performing the same.
BACKGROUND OF THE INVENTION
With the promotion of wireless technology and the popularity of
mobile phones, besides the voice communications, there are more
and more messages and emails transmitted wirelessly through the
mobile phones. However, because users can only input data through
keypad on the mobile phone, mobile phones can only transmit alphabets
and characters, but not handwriting scripts. While the keys on the
mobile phone are finite, to input data into mobile phone is a quite
time-consuming effort and complicated. Furthermore, if too many
words are necessary to be inputted, the fingers will feel ache after
a long time operation.
To improve above mention deficiency, one prior art is to embed
a touch panel into the mobile phone. For example, Nokia 6108 mobile
phone, the touch panel is hidden below the keypad of the mobile
phone for avoiding errors in typewritten. The keypad is lifted when
the user needs to input character. Writing upon the writing section
on the touch panel, the handwriting scripts are then recognized
by the program in the mobile phone, and transferred to a character
representing the script into the short message or email applications.
However, the writing section area is limited by the small size of
the mobile phone. Thereby, the user's wrist must lifts without any
support when writing on the touch panel so that cause the wrist
feel ache. Moreover, the writing section is only about 3-centimeter
squares so that long words, such as "original", "external",
etc. cannot be inputted once. Thus, the recognition software program
cannot effectively recognize the words. As a result, especially
for inputting a long sentence, the input speed is low.
Another example for the prior art to improve the input method is
the Motorola 388C mobile phone. This mobile phone is integrated
with a Personal Digital Assistance (PDA). A transparent touch panel
is overlapped on the display screen of the mobile phone. The touch
panel is used to replace the keypad completely for performing the
data input. For example, to input the phone number, a numeral keying
program is opened for the user to input numerals directly on the
screen. When input characters, a character input program is opened
for the user to input characters one by one, which are then recognized
by character recognition software.
The deficiency of this example is that the size of the mobile phone
cannot be smaller, and like the prior example Nokia 6108, the long
words still cannot be inputted once. Furthermore, the example operations
must install the handwriting recognition program in the operating
system of the mobile phone, which will increase the load of the
central processing unit, also increase the cost. Moreover, the original
scripts cannot be inputted in the handwriting recognition program,
the input way cannot be simplified. Again, the scripts and figures
cannot be converted according to the height and width of the writing
section. As a result, the heights of the input characters and drawings
cannot be arranged uniformly. Thereby, from above discussion, it
is apparent that the prior arts are not suitable for presenting
original scripts on the display screen or transmitting the original
scripts out
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide an external
device of a mobile phone for inputting and permuting original script,
which comprising a handwriting sensing device for sensing handwriting

displacement data to a mobile phone; a means for compressing or
expansion the scripts from the mobile phone into figure lattices
of the same height; and permuting the figure lattices on a display
screen of the mobile phone in order so as to form a drawing showing
original scripts. Furthermore, a method is included, which comprises
the steps of sensing handwriting script and generating script coordinates
or displacement data; transmitting the script coordinates or displacement
data to a mobile phone; compressing or expansion the scripts from
the mobile phone into figure lattices of the same height; and permuting
the figure lattices on a display screen of the mobile phone in order.

DETAILED DESCRIPTION OF THE INVENTION
In order that those skilled in the art can further understand the
present invention, a description will be described in the following
in details. However, these descriptions and the appended drawings
are only used to cause those skilled in the art to understand the
objects, features, and characteristics of the present invention,
but not to be used to confine the scope and spirit of the present
invention defined in the appended claims.
With reference to FIG. 1, the method for permuting handwriting
script of the present invention is illustrated. The object of the
present invention is to provide a more convenient and humane handwriting
input method. Thereby, by the method of the present invention, the
handwriting of the user can be displayed on the mobile phone display
screen (see FIG. 1) in order according to the principle and permutation
method of the present invention. The input device of the present
invention includes a pen 1, a digital panel 100, a mobile phone
130, an expansion LCD display module 12, and an application program
16. The digital panel 100 includes a handwriting-sensing device
10 and a transmission interface 11. A resistor or capacitor touch
panel, or electromagnetic sensing tablet performs the sensing method
of the handwriting-sensing device 10. The digital panel 100 provides
a writing section for writing thereon and detecting and collecting
the handwriting of the user. The scripts of the user are converted
into a script coordinate and displacement data. The transmission
interface 11 is used to transmit the script coordinate or displacement
data to a mobile phone by wired or wireless way.
With reference to FIG. 2, the permutation method of the scripts
is illustrated. The compressing or expansion ratios of the original
scripts are determined by the height and width of the writing section
2 and the height and width of the figure lattice 21 predefined in
the display screen 20. The formulas are: Compressing or expansion
ratio of height=Height of the figure lattice 21/Height of the writing
section 2. Compressing or expansion ratio of width=Width of the
figure lattice 21/Width of the writing section 2.
In the method, no matter what the size of the script 23, directly
compress or expand the writing section 2 to a fix sized figure lattice
21. In permutation, the figure lattice 21 with the script FIG. 22
is permutated in the display screen 20 in order. The width of the
display screen 20 is exactly full of the size of the figure lattice
21. When one row of figure lattice 21 is filled fully, it is permutated
to the start of the next row.
By this method, no matter what the size of the script 23 in the
writing section 2, using a fixed compressing or expansion ratio
to convert the whole writing section 2 into a fixed sized figure
lattice 21, it not only increase the calculation speed, but also
easier for permutation on the display screen 20. This is the advantage
of the method. The disadvantage of the method is that if the scripts
23 are not in uniform size, the converted script FIGS. 22 which
permutated on the display screen 20 will not in uniform sizes too.
To overcome this disadvantage, the present invention provides a
second method for permuting the original scripts.
Referring to FIG. 3, another method for permuting the original
scripts is illustrated. In this embodiment, the compressing or expansion
ratios of the original scripts are determined by the height of the
script 33 and the height of the figure lattice 31 predefined in
the display screen 30. The formulas are: Compressing or expansion
ratio of height=Height of the figure lattice 31/Height of the script
33. Compressing or expansion ratio of width=Compressing or expansion
ratio of height
Thereby, in the method, the compressing or expansion ratio is changed
according to the height of the script 33. The object is to make
the height of the script FIG. 32 equals to the height of the figure
lattice 31. The compressing or expansion ratio of the width is equal
to that of the height. Thus, the script FIG. 32 will not distort
after adjustment. Thereby, despite the size of the script 33 in
the writing section 3, the script FIG. 32 has the same height. Thereby,
after permutation, the size of the script FIG. 32 is identical to
have a beautiful outlook.
However, after the compressing or expansion, although the height
of the script FIG. 32 is uniform, the width is changed base on the
width of the script 33. Therefore, the width of the figure lattice
31 containing the script FIG. 32 is different. However, since the
width of the display screen 30 is fixed, in permutation, it is possible
that one row is not filled fully. Therefore, the permutation of
the method is that the figure lattices 31 containing the script
FIGS. 32 after the compressing or expansion are permuted sequentially
at one row on the display screen 30. When the surplus space is insufficient
to contain the figures lattice 31 to be permuted, the figures lattice
31 will permute to the start of the next row.
In another method of the present invention, referring to FIG. 4,
in is method the way for determining a compressing or expansion
ratio is based on the height of the writing section 4 and the height
of the figure lattice 41 predefined. It is: Compressing or expansion
ratio of height=Height of the figure lattice 41/height of the writing
section 4 Compressing or expansion ratio of width=Compressing or
expansion ratio of height
This method is suitable for the writing of English. Since the way
for writing English is from left to right transversally with a fixed
size. In this condition, the writing section 4 of the handwriting-sensing
device is designed to be suitable for being performed transversally
and to be written with a format for English. Referring to FIG. 4(A),
when the English words are written according to the format of the
writing section 4, by this method, the writing section 4 is converted
to suit the height of the figure lattice 41 by a fixed ratio. The
compressing or expansion ratio of width is identical to that of
the height so that the script FIG. 42 after compressing or expansion
will not distort, while the width of the figure lattice 41 after
conversion is corresponding to that of the script 43. Therefore,
the script 43 of English will not be adjusted to the script FIG.
42 with the same height after compressing or expansion. Words with
different lengths will not be adjusted to the figure lattices 41
with the same width to retain the original figures for English words.
In this method, the height of figure lattices 41 is identical from
script FIGS. 42 of different heights, while the width of figure
lattices 41 is changed base on the width of the script 43. Therefore,
in the permutation method, the permutation way is identical to the
second method. Namely, the figure lattices 41 containing script
FIGS. 42 after compressing or expansion are permuted sequentially
at one row of the display screen 40. When the surplus space is insufficient
to contain the figure lattices 41 to be permuted, the figure lattices
41 will permute to the start of the next row.
FIG. 1 shows the block diagram of the present invention. An original
script permutation program 14 in the diagram serves to permute the
scripts. It is illustrated that a writing section is installed on
the handwriting-sensing device 10 of the digital panel 100. The
user can write on the writing section by pen 1. The handwriting-sensing
device 10 will detect the script and transfer the script into coordinate
or displacement data. The data is transmitted to the mobile phone
130 through the transmission interface 11. At the same time, the
script data may also transmit to an LCD display module 12 to display
the tracks of the scripts on the LCD display.
When the script data is transmitted to the mobile phone 130, the
script data is received by a receiving interface 13 in the mobile
phone and then is transferred to the script permutation program
14. When the writing work is stop for a while, the script permutation
program 14 will convert the received script data into the figure
lattices with a predetermined height in accordance with the method
of present invention, and then permute the figure lattices to the
display screen 15 of the mobile phone 130. Finally, when the user
stops to input completely, the permuted script figures will form
a drawing on the mobile phone display screen 15. That drawing is
finally transferred to an application program for short messages
161 or e-mails 162 to generate an original script short message
or original script e-mail. Then the short message or e-mail is transmitted
to others through a multi-media message service (MMS) 163.
Referring to FIG. 2, a schematic view for realizing the first method
of present invention is illustrated. In FIG. 2(A), a schematic view
showing size comparison of the writing section 2 and the display
screen 20 of the mobile phone. For example, the size of the writing
section 2 is 5 units in height and 5 units in width. The size of
the display screen 20 is 2 units in height and 3 units in width.
The display screen 20 can be divided into 4 rows. Each row has six
figure lattices 21, as shown in FIG. 2(B). In this method, the compressing
or expansion ratio of the height is based on the height of the writing
section 2 (5 units) corresponding to the height of the figure lattice
21 (2 units/4, i.e., 0.5 unit). The compressing or expansion ratio
of the width is based on the width of the writing section 2 (5 unit)
corresponding to the width of the figure lattice 21 (3 units/6,
i.e., 0.5 unit). No matter what the size of the script 23 that users
write on the writing section 2, after the compressing or expansion
of the writing section 2 by the ratio mentioned above, the converted
script FIG. 22 will contained in figure lattices 21 having the same
height and width. The object is to retain the converted scripts
not to distort. Moreover, the permutation can be performed easily.
When each row is filled with six figure lattices 21, the next row
is used, as shown in FIG. 2C.
FIG. 3 shows the second method of the method for permuting handwriting
script of the present invention. The FIG. 3A is the size comparison
of the writing section 3 and the display screen 30 of the mobile
phone. For example, the height of the writing section 3 is 5 units
and the width thereof is 5 units. The display screen 30 has a height
of 2 units and a width of 3 units. The display screen 30 can be
divided into four rows, as shown in FIG. 3B. In this method, the
compressing or expansion ratio of the height is based on the height
of the script 33 corresponding to the height of the figure lattice
31. The compressing or expansion ratio of width is equal to that
of the height. No matter what the size of the script 33 that users
write on the writing section 3, after the compressing or expansion
by the ratio mentioned above, the converted script FIG. 32 will
contained in figure lattices 31 having the same height but different
width. Thereby, despite the size of the scripts 33 on the writing
section 3, they can convert to script FIG. 32 with the same height.
Then, after permutation, they are all in the uniform size, ordered
and beautiful outlook. Since the widths of the figure lattices 31
are not identical, in permutation, when the surplus space is insufficient
for containing the figure lattices 31 to permute, the figure lattices
31 will permute to the start of the next row. As shown in FIG. 3C.
Referring to FIG. 4, the schematic view about the third method
of the method for permuting handwriting script of the present invention
is illustrated. FIG. 4A is a schematic view showing the size comparison
of the writing section 4 and the display screen 40 of the mobile
phone. For example, the size of the writing section 4 has a height
of 5 units, and a width of 5 units. The size of the display screen
40 has a height of 2 units and a width of 3 units. The display screen
40 can be divided into four rows, as shown in FIG. 4(B). In this
method, the compressing or expansion ratio of the height is based
on the height of the writing section 4 (5 units) corresponding to
the height of the figure lattice 41 (2 units/4, i.e., 0.5 unit).
The compressing or expansion ratio of width is equal to that of
the height. The script 43 that users write on the writing section
4 will compress or expanse according to the ratio mentioned above,
the converted script FIG. 42 will contained in figure lattices 41
having the same height but different width. The object is to avoid
the English script 43 will not adjusted into the figure script 42
with a uniform height after compression or expansion, and the different
length words will not be compressed or expanded into the figure
lattices 41 of same width so as to retain the original figures of
the English script 43. Similarly, since the figure lattices 41 have
different widths. In permutation, when the surplus space in one
row is insufficient to contain the figure lattices 41 to permute,
the figure lattices 41 will permuted from start of a new row, see
FIG. 4C.
Referring to FIG. 5, the present invention provides an external
device of a mobile phone for inputting and permuting original script.
The user may continuously write the character, word or figures on
the writing section 5. The handwriting-sensing device senses the
script 53, and then transmits the script coordinates or displacement
data to the display screen 50 of the mobile phone through the transmission
interface, and then the script 53 are displayed on the display screen
50 without compress or expansion (referring to FIG. 5A). When the
writing action is continuous, the scripts 53 are detected continuously
(referring to FIG. 5B), the script 53 without permutation and with
the same size are displayed. When the user stops to input, the detection
of the scripts 53 are continuously. After the scripts 53 without
permutation and with the same size are displayed (referring to FIG.
5C), the original script permutation program will compress or expand
the script coordinates and displacement data by a same ratio to
a fix height figure lattices. The scripts 53 with same size are
disappeared and the figure lattices are then are permuted on the
display screen of the mobile phone. The data can be transferred
to the application program (for example, by short messages or e-mails)
to form original script short messages or original script e-mails
that are transmitted out by the multi-media message service to other
users.
Advantages of the present invention will be described hereinafter.
The scripts can be compressed or expanded with the same ratio to
be permuted from left to right at the same row. The scripts can
be converted based on the height and width of the writing section.
Furthermore, the scripts can be converted based on the height of
the script. Use a writing section with fixed height to write English
and figure scripts. The device of the present invention is an external
device with a less space. The original script is used so that the
present invention can be used in signing. Furthermore, in use of
the present invention, the wrist will not lift so that the user
will feel easy in writing.
The present invention is thus described; it will be obvious that
the same may be varied in many ways. Such variations are not to
be regarded as a departure from the spirit and scope of the present
invention, and all such modifications as would be obvious to one
skilled in the art are intended to be included within the scope
of the following claims.
