Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input device used in the field of a character input device or an input method, and more specifically, to a small electronic notebook, a small word processor (word processor), a personal computer (personal computer), or the like. The present invention relates to a screen touch input device that displays a key (soft key) on a screen and touches the key with a pen or a fingertip to input.

[0002]

[Background Art] It is possible to take out a small information device stored in a pocket, communicate with other places in text while recording the main points during a meeting, or input a manuscript on the spot on a train or car. , It's not very noticeable, and if you can do it quickly and easily, your business efficiency will improve dramatically. Personal computers and word processors are generally used as information equipment, and these have been rapidly miniaturized while improving their performance. In other words, from the desktop to the laptop, from the notebook type to the sub-notebook type, the miniaturization has come to a standstill. This is because there is a limit to miniaturization of the conventional keyboard format, and if the size of the key is simply reduced, usability is impaired.

Therefore, some portable personal computers, electronic notebooks, personal digital assistants (PDs) used for corporate sales tools, etc.
In A) etc., cut off the "key input" that is too small to hit, and put the screen on the "pen" or "fingertip", especially "pen".
"Screen touch type input" that touches and inputs using is introduced.

By the way, "pen input" allows direct input to the screen using a touch pen like a mouse.
It is suitable for selecting information displayed on screens such as menus and lists.

On the other hand, with this "pen input", characters, numbers,
In order to input a symbol or the like, a method of directly “handwriting input”, a “QWERTY arrangement” which is a character arrangement in a conventional general keyboard as shown in FIG. 16 and a kana character as shown in FIG. 17 are displayed on the screen. A method has been used in which an input "Japanese syllabary arrangement" is displayed and each key (soft key) is touched with a pen to input.

[0006]

However, in the method of "handwriting input", the recognition rate of handwriting input is not necessarily high, and after recognition, it must be converted into kanji, katakana, hiragana, etc. Input "→
You have to go through the steps of "recognition" → "conversion",
There is a problem that input operation takes time and labor, and operability is not good.

On the other hand, in the method of displaying the "QWERTY arrangement" and the "Japanese syllabary arrangement", the number of keys is large because the arrangement is 10 rows and 4 to 5 rows, and the size of each key on the screen is large. Are small and are densely packed, it is necessary to carefully hit with your fingertips while looking closely at the hand, and the amount of movement of the pen when touching each key, that is, the amount of movement of the hand holding the pen, increases There was a problem that it was difficult to input because it was low.

An object of the present invention is to provide a screen touch input device which is simple in operation and can be quickly input when a key is displayed on the screen to input characters, numbers, symbols and the like by touch. Especially.

[0009]

In the screen touch input device 1 of the present invention, a screen 3 is provided with a main key area 20 consisting of 15 main keys 21 to 35 arranged vertically in three rows and five columns in the left and right. An arrangement switching means 73 is provided for switching the arrangement of the symbols displayed on the main keys 21 to 35 and the symbol codes generated when the keys 21 to 35 are touched.

According to the present invention as described above, the main key 2
Since the arrangement of the symbol codes set to 1 to 35 can be switched to various arrangements such as Japanese Roman alphabet input (standard arrangement), English arrangement, numeral arrangement, and symbol arrangement, the main keys 21 to 35 are set to 15 Even if there are only one key, 15 keys x the number of arrays can be set, and each symbol (letter, number, symbol, etc.) can be directly touch-input by simply switching the array, and it is possible to easily input.

Also, the number of 15 keys is the same as the conventional QWER.
Since it is much smaller than the TY layout or the Japanese syllabary layout, if the main keys 21 to 35 are displayed in the same size as the keys of the conventional QWERTY layout or the Japanese syllabary layout, the key display area becomes smaller, and the touch screen type The input device 1 can be further downsized, and the movement amount of the pen 15 that touches the keys 21 to 35 can be reduced to improve the operability.
On the other hand, the area where the main keys 21 to 35 are arranged is changed to the conventional
If it is made equivalent to the key arrangement area of the RTY arrangement or the Japanese syllabary arrangement, the size of each main key 21 to 35 can be made larger than before, and the keys 21 to 35 can be easily touched with the pen 15 or fingertip. Also improves operability.

A screen touch input device according to a second aspect is the screen touch input device 1 according to the first aspect, wherein at least some keys 21 to 35 of the main keys 21 to 35 are set to a shift state. It is characterized in that a shift input means 71 for switching to any of the non-shifted states is provided.

In this case, the main keys 21 to 35 are 1
Even if only five keys are provided, the shift input means 71 can set at least two keys (symbols), that is, at least 30 keys in total for each of the keys 21 to 35. Therefore, the alphabet used to input Japanese in Roman letters, that is, the vowels "A", "I",
"U", "E", "O" and the vowel key in combination with the Japanese "ka" line to "wa" line to input a pure sound "K", "S", "T", "N" , "H", "M",
"Y", "R", "W", and "G", "Z", which inputs Japanese voiced and semi-voiced voices in combination with vowels
Each key can be set to the main keys 21 to 35 by including the punctuation mark "," and the reading mark "." In addition to the 19 characters "D", "P", "B", and a key layout for Japanese input. By setting, you can fully support Japanese input without switching to another keyboard layout. Similarly, in addition to the 26 letters of the alphabet, commas “,”, periods “.”, Etc. can be set in the main keys 21 to 35, and if a key arrangement for English input is set, it is possible to sufficiently input English.

Further, even if there are only 15 main keys 21 to 35, the shift input means 71 and the arrangement switching means 7 are provided.
By combining with 3, it is possible to set 30 keys x the number of arrangements, and it is possible to input each symbol (letter, numeral, symbol, etc.) more easily.

Here, on the screen 3, an English switching key 42 adjacent to the main key area 20 for switching the 15 main keys 21 to 35 of the main key area 20 from the standard arrangement to the English arrangement, and the standard arrangement The number switching key 43 for switching from the standard to the numerical arrangement and the symbol switching key 41 for switching from the standard arrangement to the symbol arrangement are displayed, and the arrangement switching means 73 changes the arrangement of each main key 21 to 35 to each switching key 41. Alternatively, it may be configured to switch for the arrangement selected in steps 43 to 43. In this case, by touching the switching keys 41 to 43, the arrangement of the main keys 21 to 35 can be easily switched to input not only Roman characters but also English, numbers,

"N ・ KI ・ KU ・ CHI ・ TSU ・ TU" has a high frequency of occurrence in Japanese, especially on-reading Kanji characters, so you usually have to input these characters once or twice. If you can input with, the number of touches will decrease and the input efficiency will increase. Table 1 shows an example in which the number of touches is compared with the conventional kana input in the Japanese syllabary arrangement and the Roman input in the QWERTY arrangement.

[0069]

[Table 1]

As can be seen from Table 1, the use of the high-speed array of FIG. 7 allows the input of double vowels and syllabary with one touch, so that the number of touches (each number in Table 1 is different from that of kana or romaji input). ) Can be reduced, and its effect can be enhanced especially in sentences with many phonetic reading words.

Further, the high-speed array is designed so that the flow of character input sequentially shifts from right to left. That is,
Touch the consonant on the right, then the vowel on the left, or the double vowel, and then touch the second syllable on the left, "n, ki, ku, chi, tsu, tsu". Can be reduced and operability can be improved. If the second syllable in a Kanji reading with two syllables is other than a vowel, this is
One of the characteristics of Japanese is that there is a high possibility that "n ・ ki ・ ku ・ chi ・ tsu ・ tsu" will be input after the first syllable (consonant + vowel). It was made paying attention to, and is very effective in inputting Japanese.

The Kanji characters including these characters are as follows. 1) Example of Kanji whose second syllable is "i" (example of which is one of "AI, UI, EI" of double vowel) -Holding (KAI SAI) -Inside and outside (NAI GAI) -Accounting (KAI KEI)・ Analog analogy (RUI SUI) ・ Estimation (SUI TEI) ・ Cumulative (RUI KEI) 2) An example of a kanji whose second syllable is “U” (an example of which is either “UU · OU” of a double vowel) and Examples of Kanji including "YUU" and "YOU" ・ Method (HOU HOU) ・ Structure (KOU ZOU) ・ Factory (KOU ZYOU) ・ Tokyo (TOU KYOU) ・ Ventilation (TUU FUU) ・ Central (TYUU OU) 3) Example of Kanji whose second syllable is "n" ・ Safe (A ZE) ・ Easy (KA TA) ・ Chaos (KO TO) 4) Kanji whose second syllable is "KI" Examples: ・ Trust (HE, E) ・ Exact (TE, KA) ・ Painting (KA, SA) ・ Purpose (MO, TE) ・ Nemesis (SYU, TE) ・ Instant (SO, SE) 5) Example of Kanji in which the second syllable changes to "Ji Tsu" Chi) ・ Yoshihi (KI Chi ZI) ・ Quality (SI one ZI) ・ Cut (SE SE ZI) ・ One day (I Chi NI Chi) ・ Active (KA PA) ・ Real (ZI SI) ) ・ Departure (PA SYU)

As the shift input means 71, any one of the push button type shift input means 81, the click type shift input means 82, the pre-shift type shift input means 83, and the area division type shift input means 84 is set. However, a plurality of shift input means 71 may be set so that the user can select them appropriately. The push button 4 and the shift key 5 may not be provided in the main body 2 when the push button type shift input means 81 and the pre-shift input means 83 are not used as the shift input means 71.

Further, when the high-speed arrangement shown in FIG. 7 is selected, since the keys 33 and 34 are set to the first and second shift states, the shift input means 71 also has the first and second shift states. It is necessary to set two second shift input means of different systems. For example, the push-button shift input means 81 may be set as the first shift input means, and the click shift input means 82 or the like may be set as the second shift input means. In this case, for example, when the keys 33 and 34 are touched while pressing the button 4, the punctuation marks “,” and the reading marks “.” In the first shift state.
Is input, and the keys 33 and 34 are clicked (touched twice within a certain period of time), the second
"F" and "V" in the shift state are input.

Next, the effect of this embodiment will be described. According to the present embodiment, even if only 15 main keys 21 to 35 are provided, at least 2 keys are provided to each key 21 to 35 by the shift input means 71.
It is possible to set one key (the key set in the shift state and the key set in the non-shift state), that is, at least 30 keys in total. Therefore, the alphabet used when inputting Japanese roman characters, that is, the vowels "A", "I", "U", "E", "O", and the vowel key in combination with the Japanese "ka" line "K", "S", "T", "N",
"H", "M", "Y", "R", "W", and "G", "Z", "D", "P" for inputting Japanese voiced and semi-voiced sounds in combination with vowels , "B" as well as punctuation marks "," and reading marks "." Can be set in each of the main keys 21 to 35, and a small number of keys can sufficiently cope with Japanese input. Similarly, alphabet 26
In addition to characters, commas ",", periods "." And the like can be set in the main keys 21 to 35, and English input can be sufficiently supported.

Therefore, 15 main keys 21 to 23, which are significantly smaller than the conventional QWERTY arrangement and the Japanese syllabary arrangement, are used.
It is possible to input Roman characters and English by using 5. For this reason, each key 21-35 is replaced with the conventional QWERTY.
If the keys are arranged on the screen 3 in the same size as the keys in the arrangement or the Japanese syllabary arrangement, the main key area 20 which is the key display area can be made small, so that the movement amount of the pen 15 that touches the keys 21 to 35 can be reduced, and the operation can be performed. It is possible to improve the property.
In addition, since the main key area 20 can be made small, the screen touch input device 1 can be made compact, and the display area 10 for data and the like can be made large, so that handling and operability can be improved. .

On the other hand, the main key area 20 is the same as the conventional QW.
The size of each main key 21-35 can be made larger than the conventional size by making the size of the key arrangement area of the ERTY arrangement or the Japanese syllabary arrangement almost equal to the conventional size, and the keys 21-35 can be easily touched with the pen 15 or fingertip. It is possible to improve the operability in this case as well.

Further, in the present embodiment, the switching keys 41 to 41
43 and each menu key 1 in the selection menu 11
Since 6 to 19 and the array switching means 73 are provided, the array of the main keys 21 to 35 can be switched to seven types. Therefore, not only the alphabet, but also numbers and symbols, and various key arrangements such as an arrangement similar to the conventional QWERTY arrangement can be set. Therefore, the arrangement of the symbol codes set in the main keys 21 to 35 is used for inputting Japanese Roman letters (standard arrangement), English arrangement, numeral arrangement, symbol arrangement, high speed arrangement, QWERTY English arrangement,
You can switch to 7 types of QWERTY Japanese-only layout, and even if you have only 15 main keys 21-35,
By combining the shift input means 71 and the arrangement switching means 73, 30 keys × the number of arrangements can be set, and each symbol (letter, numeral, symbol, etc.) can be easily input.

Further, the switching key 4 is used for switching each array.
1 to 43 and each menu key 16 to 19 need only be touched, so you can easily switch the arrangement of each main key 21 to 35 and input not only Roman letters but also English, numbers and various symbols. You can

Further, since each array switching means 73 is configured to switch not only the main keys 21 to 35 but also the function keys 51 to 56 displayed in the function key area 50, it is possible to match each array. The function keys 51 to 56 can also be set, and the operability can be further improved. For example, by not displaying functions such as "Kanji conversion" required only for Japanese input in the English layout, only required function keys can be displayed, further improving operability.

2 and 7, the vowel part keys and the consonant part keys are separately arranged in the vowel area 20A and the consonant area 20B, so that consonants and vowels alternate. It is possible to easily recognize the position of the vowel key, which has a particularly high frequency, when inputting the appearing Japanese romaji, and improve the operability. Also, among the consonants, the consonants that are used most frequently are set to the non-shifted state of each key, so there is no shift operation when inputting the frequently used consonants. can do.

In addition, the keys "A" and "K", which are frequently used in vowels and consonants, are set to the keys 27 and 28 near the center of the main key area 20. , In the order from the bottom, the vowel "A",
"I", "U", "E", "O" and consonant "K",
"S", "T", "N", "H", "M", "Y",
"R", "W", that is, "ka" line to "wa" line are arranged in order so that the key layout can be easily grasped,
The operability can be further improved.

Furthermore, "K" in the consonant area,
For each of the "S", "T", "N", and "H" shift states,
In combination with the vowels "A", "I", "U", "E", and "O", "G", which inputs Japanese voiced and semi-voiced voices,
Since "Z", "D", "P", and "B" are arranged,
Corresponding to the input position of "ka", "sa", "ta", "ga",
"Za" and "da" are arranged according to the input positions of "na" and "ha", so that "pa" and "ba" are arranged respectively, making it easier to remember the key positions of the voiced sound and the semi-voiced sound. The operability can be further improved.

In the standard arrangement (FIG. 2), the high-speed arrangement (FIG. 7) and the QWERTY-type Japanese-only arrangement (FIG. 9) for inputting romaji, syllable “n”, consonant “tsu” and punctuation which are frequently used in Japanese. Since ",", the reading point ".", And the long sound "-" are also set in a part of the main keys 21 to 35, even with a small number of keys, the sound repellency "n", the consonant "tsu", the punctuation ",", The punctuation mark "." And the long sound "-" can be input with one touch operation, and the operability can be improved. In particular, since the sound repellency "n" is set in the key 31 or the key 35 in the non-shifted state, it is possible to easily input the sound repellency "n" which has a high frequency particularly in Japanese reading Kanji characters.

On the other hand, even when the main key is set for the English layout (FIGS. 4 and 8), a comma ",", a period ".", Etc., which are frequently used in English input, are shifted or changed in each key. Since it is set to the non-shifted state, direct touch input is possible, and operability when inputting English can be improved.

Furthermore, the English layout of FIG. 4 has the same key layout as the standard layout of FIG. 2, and the QWE of FIG.
The RTY-type English-only layout has many key layouts that match the QWERTY-style Japanese-only layout of FIG. 9, so even if the standard layout and English layout are switched and used together, the key layout is easy to remember and operability. Can be improved.

In the number arrangement shown in FIG. 5, the numbers can be arranged in the same manner as the numeric keypad on the conventional keyboard, and various symbols used for calculation can be touch-inputted, so that the numbers can be easily input and calculated. You can

In the symbol array shown in FIG. 6, various symbols that are difficult to enter are displayed for each main key 2 even though they are frequently used.
1 to 35 can be displayed by touch input,
You can easily enter various symbols. In addition, since each parenthesis symbol is set to the shift state and the non-shift state of the six main keys 21, 22, 26, 27, 31, 32 arranged in two rows on the reference side, the parenthesis symbol is set. It is possible to easily determine the key positions of and other symbols, and improve the input operability.

In the high speed array shown in FIG. 7, the vowel area 20
In the shift state of each key 21, 22, 26, 27, 31, 32 of A, "AI", "UI", "UU", which are double vowels and gospels that are frequently used in Japanese, especially in reading kanji,
Since "EI", "OU", and "YUU" are set and these characters can be input with one touch, the input efficiency of Japanese can be improved.

In addition, in the high-speed arrangement, the keys 41, 42, and 43, which are normally used as switching keys, are in the shift state and the non-shift state, that is, "tsu", "ku", and consonant "tsu",
Since the keys for entering "chi", "ki", and "YOU" are set, the "ki-ku-chi-tsu-tsu" that frequently appears in the second syllable of Japanese single Kanji is read as 1 In addition to being able to input with one touch, the character "YOU" accompanied by double vowels, such as Tokyo (TOU KYOU), can be input with one touch, further improving input efficiency. Furthermore, these keys take advantage of the fact that they frequently appear in the second syllable, and after any key in the main key area 20 is touched, the setting of the switching keys 41 to 43 is set to "ki-ku-chi-tsu.
, Etc., and usually the same switch key 41 as other arrangements
.. to 43, the keys 41 to 43 can be shared by appropriately switching them depending on the situation, and the number of keys can be reduced without impairing operability.

Further, at the time of high speed arrangement, the main key 3
In the shift states of 3 and 34, the punctuation mark “,” and the reading point “.” As the first shift state and “F” and “V” as the second shift state are set. "Fa (F +
It is possible to easily input “F” and “V” used when inputting “A)” and “Va (V + A)”, and particularly to improve operability when inputting Katakana.

In the QWERTY-type English-only array and Japanese-only array shown in FIGS. 8 and 9, the key sequence of the QWERTY array, which has been widely used and familiar to the user, can be set to 15 main keys. Those who are used to can easily learn the keyboard layout,
Can be used immediately.

If the click input shift input means 82 and the area division type shift input means 84 are used as the shift input means 71, shift input and non-shift input can be performed only by slightly changing the touch method with the pen 15. Can be used properly and operability can be improved.

When the click type shift input means 82 is used, the shift operation can be performed by touching twice within a predetermined time. Therefore, the same operation as the double click of the mouse can be performed, which is an operation familiar to the user. be able to. At this time, if the user of the input device 1 can appropriately adjust the touch determination time, even if the interval between the two touches differs depending on each user, the one touch and the two touch are shifted, that is, the shift is performed. It can be accurately determined whether or not the operation.

When the area division type shift input means 84 is used, the shift operation can be performed by simply changing the area to be touched with the pen 15 and the operability can be improved. In this case, the symbols set in the shift state and the non-shift state in the main keys 21 to 35 are displayed in the shift areas 84A and the non-shift areas 84B, and the respective areas 84A and 84B, that is, the symbol portion to be input are displayed. Since each symbol can be entered by a very intuitive operation of directly touching, the operation is easy to understand and the operability can be improved.

On the other hand, the push button type shift input means 81 and the pre-shift type shift input means 83 have the pen 15 while pushing the push button 4 or after pushing the shift key 5.
Since it suffices to touch with, it is not necessary to pay attention to the way of touching the pen 15, it can be operated explicitly, and for users who are not accustomed to fine movements,
In some cases, it may be easier to operate than when performing a shift operation by changing the touch method.

Further, when the pre-shift type shift input means 83 is used, when a plurality of keys in the shift state are successively input, if the shift state is set first, it is necessary to perform any shift operation at the time of subsequent key touch. Therefore, the input efficiency can be improved.

Further, in the above-described embodiment, since the keys of the key input area 12 are arranged apart from each other, the areas of each key are clearly divided, and when the touch input is performed with the pen 15 or the like, two keys are input. It is possible to prevent erroneous operations such as inputting over keys. In particular, when a touch is made to a gap between the keys, setting is made so as to cancel the touch input from the gap so that an erroneous operation can be reliably prevented.

Further, the array switching means 73 is not limited to the one displayed on the liquid crystal screen 3 as described above, but may be provided in the main body 2 in a button type.

Further, the arrangement of the main keys 21 to 35 displayed in the main key area 20 is the standard arrangement or the Q arrangement.
The arrangement is not limited to the WERTY type arrangement. For example, vowel area 2
It is also possible to arrange 0A in the lower row and consonant areas 20B in the upper middle two rows. Further, in the standard arrangement or the high-speed arrangement, the vowel area 20A and the consonant area 20B may be reversed left and right, and the arrangement order of each key may be reversed, so that the keys are symmetrically set. In addition, the switching key area 40
Also, the function key area 50 may be arranged in another place such as on the right side or the upper side of the main key area 20, and the arrangement position of each of these key areas 20, 40, 50, etc. should be considered in consideration of the user's dominant hand. It may be set appropriately.

As the touch means, a fingertip or the like may be used instead of the pen 15. Also, the screen is not limited to the liquid crystal screen 3, and a CRT screen or the like may be used. Here, as the means for recognizing the touch of the pen 15 or the like, various types such as capacitance type, optical type, resistance type, etc. can be used according to the screen type and the like, and the touch means can be appropriately used according to the recognizing means. Just select it. Further, when each key is touched, each touched key may be highlighted so that it can be easily grasped which key is touched.
At this time, if the inverted display state is changed between the touch involving the shift operation and the normal touch, for example, in the case of the shift operation, only the upper half of the key is inverted, and in the case of the normal operation, the key If the lower half is inverted, there is an advantage that the touch input operation can be grasped more easily.

Further, in the present invention, the shift input means 71 may not be provided, but only the array switching means 73 may be provided.
In this case, only one symbol or the like can be set for each key, but this can be dealt with by adding various key arrangements.
