Description

Mobile phone external handwriting original trace arrangement input device and arrangement method

technical field

The invention relates to an external handwriting original trace arrangement input device and arrangement method for a mobile phone.

Background technique

With the rapid improvement of wireless communication technology, the penetration rate of mobile phones has greatly increased. It has become an indispensable communication and contact tool for human beings. Due to the advancement of technology and the rapid and vigorous development of the information industry, especially the design is light and does not occupy space. , and in addition to using general phone functions (speaking, chatting), sending text messages (short messages) and e-mails are also increasing, but mobile phone text messages and e-mails can only send general text, and cannot send real handwriting. , traditional text messages can only use general text, but use the keys to define several characters, such as the symbols ㄅ, ㄈ, ㄋ or English symbols a, b, and c that define the phonetic input method in the number key 1 on the mobile phone, the user needs to input During text, must press several times on the same key and obtain its required symbol, if the user needs " Ya " word must be pressed three times on number key 1 and obtain " Ya " or " c " symbol, again by moving The intelligent input judgment in the phone processes the candidate word, and then the user presses the direction key to find the character it needs, so the user must press several times or even press the button of the mobile phone in order to input "a word". More than a dozen times, if the user needs to create a "series of words" in the SMS or email program function, the user must press the button of the mobile phone dozens or even hundreds of times. The potential disadvantage of such a frequent number of times is that It is easy to shorten the service life of the mobile phone keys, and the continuous short-term pressing is also likely to cause injury to the user's fingers;

In order to solve the problem that the key input method in the mobile phone still cannot allow the user to input more easily and quickly, another conventional method is to combine a touch panel in the mobile phone, such as Nokia's model 6108 mobile phone, which uses a touch panel It is hidden under the number key panel to avoid misoperation caused by accidental touch. If the user needs to input text, the key panel can be lifted up, and the handwriting input method can be selected to write directly on the panel, and then use the recognition software in the mobile phone to read The inputted handwriting is recognized as text and then sent to SMS and email applications. However, mobile phones are required to be thin, light and small, which limits the area where the user can write is too small, resulting in the need to leave the wrist free when writing, due to incorrect posture Cause wrist discomfort, unable to write according to personal habits, resulting in unreliable handwriting, and can only input and recognize Chinese or English characters one by one in an area of about 3 square centimeters, and it is impossible to write a longer one in a small area English words, such as: original, external English words with long characters, so the recognition software cannot 100% correctly recognize the characters written by the user, resulting in the user being unable to write quickly and in large quantities in the writing area , and because of the difficulty of deepening the writing of the complete sentence, and then giving up the writing function, another conventional method is like the Motorola 388C mobile phone, which uses a personal digital assistant (PDA) to integrate the mobile phone device, and uses a transparent touch panel to completely Instead of buttons, its input is completely replaced by a touch panel. When the user needs to press a number, it can open the numeric keypad application to allow the user to directly touch the panel to input numbers. If it is necessary to enter text, open the text input recognition application for use Or the character-by-character input recognition software is recognized as text, because the disadvantage of this method is the same as Nokia's model 6108, which requires character-by-character input, which makes the mobile phone too bulky, and its operating system must be installed with handwriting Recognition software, so that the central processing unit of the mobile phone is loaded with a considerable amount of work capacity (such as handwriting recognition calculations, application program execution capabilities, etc.), which increases the cost of manufacturing. Moreover, the original handwriting recognition software cannot be used Writing, the input method cannot be simplified, and it is impossible to convert English, Chinese, and graphics according to the height and width of the writing area. It is difficult to input data and the coordinates and displacement tracks cannot be proportionally scaled to a fixed column height. In the case of displaying on the phone screen, it is easy to cause the shortcomings of inconsistency in the layout of the written graphics and texts. It can be seen that the input of the above-mentioned conventional mobile phones, whether it is by pressing several times or including handwriting recognition software in the mobile phone, it is still the same. The traditional text representation cannot display the user's original handwriting, and it still has many shortcomings. It is not a convenient and practical use, and needs to be improved.

Detailed ways

Please refer to Fig. 1, mobile phone external type handwriting original trace arrangement input device of the present invention comprises pen 1, tablet 100, mobile phone 130, expansion LCD display module 12, application program 16, wherein tablet 100 comprises handwriting handwriting sensing device 10 And transmission interface device 11, handwriting handwriting sensing device 10 (sensing mode) can be resistive touch panel, capacitive touch panel or electromagnetic induction digital board, and its purpose is to provide writing area to allow user to write text on it , and detect and collect the handwriting of the user, and convert it into handwriting coordinates or displacement data; the transmission interface device 11 is used to transmit the handwriting coordinates or displacement data generated by the handwriting sensing device 10 to the mobile phone, which The transmission mode can be wired transmission mode or wireless transmission mode.

The method for zooming and arranging the original track of the present invention is as shown in Figure 2, with the height and the width of the writing area 2 of the handwriting sensing device, and the height and the width of the predefined graphic grid 21 on the display screen 20, to determine the original The scale at which traces are scaled in the following way:

The scaling ratio of the height=21 height of graphic grid/20 height of writing area

Scaling ratio of width = graphic square 21 width/writing area 20 width

Regardless of the size of the handwritten handwriting 23 in the writing area 2, this method directly scales the entire writing area 2 to a fixed-size graphic grid 21. When arranging, the graphic grid 21 that contains the handwriting graphic 22 is arranged in sequence. On the display screen 20; because the width of the display screen 20 can be designed to just fill up the size of several graphic squares 21, when a row is full, directly change to the next row and then start again;

Scale the entire writing area 2 to a fixed-size graphic square 21 with a fixed scaling ratio, regardless of the size of the handwriting 23 written by the user in the writing area. Not only is the scaling operation faster, but also the It is also relatively easy to arrange on the display screen 20, which is the biggest advantage of this method; the shortcoming of this method is that if the size of the handwriting 23 written by the user is inconsistent each time, after scaling and arranging on the display screen 20, the The size of the handwriting graphics 22 seen is also inconsistent. Therefore, for this shortcoming, the present invention provides a second method for scaling and arranging the original handwriting.

As shown in Fig. 3, the present invention provides another kind of method of zooming and arranging original traces, that is, the height of the handwriting 33 written by the user in the writing area 3 is compared with the predefined graphics on the display screen 30. The height of grid 31 is used to determine the scaling ratio of height and width when the original trace is scaled, and the method is as follows:

The scaling ratio of the height=31 height of graphic grid/33 height of handwriting

Width Scale = Height Scale

In this method, when scaling, the scaling ratio will be changed according to the height of the handwriting 33 written by the user in the writing area 3, and its purpose is to allow the height of the scaled handwriting figure 32 to be equal to the height of the figure grid 31, Making the scaling ratio of the width the same as the scaling ratio of the height can make the scaled handwriting figure 32 not distorted; in this way, regardless of the size of the handwriting 33 written by the user in the writing area 3, it can be scaled to With the handwriting graphics 32 of the same height, after being arranged, there is no longer any situation of different sizes, and they are neat and beautiful;

Although the height of the handwriting graphics 32 obtained after zooming by this method is consistent, the width will vary due to the size of the handwriting 33 that the user writes each time. Therefore, the width of the graphic grid 31 that contains the handwriting graphics 32 will also be different. , yet, because the width of display screen 30 is fixed, so there will be the situation that same column can't be filled up just when arranging; The same column on the display screen 30 is arranged sequentially, and when the remaining space of the column is not enough to accommodate the graphic grid 31 to be arranged, the graphic grid 31 is arranged again from the next column.

As shown in Fig. 4, the present invention provides another kind of method of zooming and arranging original traces, that is, the height of the writing area 4 of the handwriting sensing device and the height of the predefined graphic grid 41 on the display screen 40, To determine the scaling ratio of height and width when the original track is scaled, the method is as follows:

Scaling ratio of height=figure grid 41 height/writing area 4 height

Width Scale = Height Scale

This method is suitable for English writing mode. Since English writing is written horizontally from left to right, and its size has certain rules, we can design the writing area 4 of the handwriting sensing device as a form suitable for horizontal writing, and It is planned into the format of English writing, as shown in Figure 4 (A); after the user writes English text according to the format of the writing area 4, this method scales the entire writing area 4 to the height of the graphic square 41 according to a fixed ratio, and The scaling ratio of the width is the same as the scaling ratio of the height, so that the scaled handwriting figure 42 is not distorted, but the width of the scaled graphic square 41 will correspond to the width of the scaled handwriting 43; The handwriting 43 will not be adjusted to the handwriting graphics 42 with the same height after scaling, and the English characters of different lengths will not be scaled to the graphic grid 41 with the same width, but the original appearance of the English handwriting 43 can be maintained;

Although the heights of the handwriting graphics 42 obtained after zooming by this method are different, they will all be included in the graphic squares 41 with the same height, and the width of the graphic squares 41 will follow the handwriting 43 written by the user each time. Therefore, the arrangement mode of this method is the same as the method for zooming and arranging the above-mentioned second original trace of the present invention; The same column is arranged sequentially, and when the remaining space of the column is not enough to accommodate the graphic grid 41 to be arranged, the graphic grid 41 is arranged again from the next column.

The actual implementation of the above-mentioned method of the present invention will be described in detail below.

Fig. 1 is shown as the block diagram of implementation of the present invention, and the method for zooming and arranging of the original trace of handwriting is accomplished by the zooming and arranging program 14 of the original trace in the figure; Embodiment is as follows:

The handwriting sensing device 10 of the tablet 100 is provided with a writing area, and the user can use the pen 1 to write characters on the writing area, and the handwriting sensing device 10 will detect the handwriting written by the user and convert it into coordinates or displacement data of the handwriting , the data is then transmitted to the mobile phone 130 via the transmission interface device 11; while the transmission interface device 11 is transmitting the handwriting data, it can also transmit the handwriting data to the LCD display module 12 at the same time, so that the trajectory of the handwriting is displayed on the LCD display at the same time superior.

When the handwriting data is sent to the mobile phone 130, it is received by the receiving interface device 13 in the mobile phone 130, and then sent to the original trace zooming and arrangement program 14; when the user's writing action is suspended for a period of time, the original trace zooming and arrangement program 14 is The coordinates or displacement data of the collected handwriting will be scaled into a graphic square with a fixed height according to the scaling and arrangement method of the original handwriting of the present invention, and then neatly arranged on the display screen 15 of the mobile phone 130 in order, and finally , when the user completely stops inputting, an image and text arranged by the original trace graphics will be formed on the display screen 15 of the mobile phone 130; The program 16 is to form an original text message or an original email, and then send it to other users via the Multimedia Message Service (MMS) 163 .

Fig. 2 is a schematic diagram of the implementation of the first method in the method for zooming and arranging the original handwritten traces of the present invention. Fig. 2A is a schematic diagram of the size comparison between the writing area 2 and the display screen 20 of the mobile phone, for example, the size of the writing area 2 is 5 unit, 5 units wide, and the size of the display screen 20 is 2 units high and 3 units wide, and the display screen 20 can be planned into four columns, with six graphic squares 21 in each column, as shown in Figure 2B; the height scaling of this method The ratio is based on the height of the writing area 2 (5 units), corresponding to the height of the graphic square 21 (2 units/4, that is, 0.5 units); the scaling ratio of the width is based on the width of the writing area 2 (5 units), corresponding to the graphic The width of square 21 (3 units/6, namely 0.5 units); the handwriting 23 written by the user in the writing area 2, regardless of the size, will be the handwriting pattern formed after the entire writing area 2 is scaled according to the above-mentioned ratio 22, all will be accommodated in the same height and same width of the graphic square 21, the purpose of this is to maintain the converted handwriting without distortion on the one hand, and on the other hand, it is very easy to arrange, and each column is fixedly filled with six graphic squares grid 21, just change to the next column and arrange again, as shown in Figure 2C.

Fig. 3 is the schematic diagram of the embodiment of the second method in the zooming and arranging method of the original handwritten traces of the present invention. Fig. 3A is a schematic diagram of the size comparison between the writing area 3 and the display screen 30 of the mobile phone, for example, the size of the writing area 3 is 5 unit, 5 units wide, and the size of the display screen 30 is 2 units high and 3 units wide, and the display screen 30 can be planned into four columns, as shown in Figure 3B; the height scaling ratio of this method is the height h of the handwriting 33 , corresponds to the height of the graphical square 31; the scaling ratio of the width is equal to the scaling ratio of the height, the handwriting 33 written by the user in the writing area 3, regardless of the size, after scaling according to the above ratio, the formed handwriting graphics 32, All will be contained in the graphic grid 31 of the same height but unequal width. The purpose of this is that regardless of the size of the handwriting 33 written by the user in the writing area 3, it can be scaled to have the same height. Figure 32, after making arrangement, no longer have the situation of different sizes, and neat and attractive in appearance; Because the width of figure grid 31 is not uniform, when arranging, when the remaining space of this column is not enough to accommodate the figure grid of desire to arrange 31, then the graphic grid 31 is arranged from the next column and then restarted, as shown in Figure 3C.

Fig. 4 is the schematic diagram of the embodiment of the third method in the zooming and arranging method of the original handwritten traces of the present invention. Fig. 4A is a schematic diagram of the size comparison between the writing area 4 and the display screen 40 of the mobile phone, for example, the size of the writing area 4 is 5 unit, 5 units wide, and the size of the display screen 40 is 2 units high and 3 units wide, and the display screen 40 can be planned into four columns, as shown in Figure 4B; the height scaling ratio of this method is based on the height 5 units of the writing area 4 unit, corresponding to the height (2 units/4, 0.5 units) of the graphic grid 41; After the writing area 4 is scaled according to the above ratio, the formed handwriting graphics 42 will all be contained in the graphic squares 41 with the same height but different widths. The purpose of this is to prevent the English handwriting 43 from being enlarged Adjusted to have the handwriting graphics 42 of the same height, English words of different lengths will not be scaled to the graphic grid 41 with the same width, but can maintain the original appearance of the English handwriting 43. Similarly, due to the width of the graphic grid 41 Not one, when arranging, when the remaining space of the column is not enough to accommodate the graphic grid 41 to be arranged, then the graphic grid 41 is arranged again from the next column, as shown in Figure 4C.
