Description

 Information input device

 The present invention relates to an information input device, and more particularly to a small keyboard which can greatly reduce the number of keys and the size of a keyboard. Background technique

 Data input is a must-have feature for a variety of electronic devices. Keyboard input is still a leader in speed and accuracy in most current input methods. As electronic devices continue to be smaller, input devices are shrinking in size.

 In the prior art, there are certain restrictions on the miniaturization of the keyboard. First of all, in order to make it easy for the user to input with a finger, the size of the button cannot be too small, and if the button is too small, it is not impossible to operate with a finger, and it is easy to cause an erroneous operation. Second, in order to be able to enter enough numbers and characters, it is important to ensure that the keys have a sufficient number of keys. It restricts the miniaturization process of the keyboard for two aspects.

 The standard keyboard can only hit one button at a time, if a syllable is completed with two keys,

The speed of 120 words/minute is recorded in the syllable of Chinese. It requires 240 keystrokes per minute and 4 keystrokes per second. This is not easy for ordinary people to achieve; and the fingers are extremely fragile and cannot work for a long time.

 There is currently a speed recorder on the market that enables a combination of miniaturized keyboard size and fast recording. As shown in Fig. 9, the design of the keyboard for the deck is shown.

 The special keyboard of the deck is as shown in the figure, divided into left and right parts, each of which has 12 key positions. The arrangement of the key codes is the same as the two sides, and the uppercase Latin letters are printed. The left key code is for the left hand, the right is for the right hand, and the left and right hands control the key code, each including 4 vocoding (B, D, Z, G), 6 rhymes (1, U, N, E, Λ, 0) and two function codes (X, W). "X" also doubles as a combination of vocoding codes.

 The pronunciation of the key code is as follows:

 The key codes are arranged in a certain order. The "X" and "B" are arranged at the top, and are arranged according to the principle of "from top to bottom, from the middle to both sides". The order is:

 X B D Z G W I U N E A 0

The order of the key codes is fixed and always written from left to right in order. However, in order to take care of the reading habits, all "N" and "A" appear at the same time, or "AN". The key codes controlled by the left and right hands include the initial code (voq), the final code (rhythm code) and the function code (X, W). The design principles of the decking code are described below. Take the design principle of its vocoding as an example.

 Coding scheme

 The key code used to compile the vocode is itself only four vocodes, namely "B (bu) ", "D (de)",

"Z (zhi) ", "G (ge)", the rest must be formed by combining these key codes.

 The encoding of all 21 vocodes is as follows:

 The code has a total of 21 vocoding codes, all of which have a fixed pronunciation, corresponding to a fixed syllable code. This is the syllable code represented by the vocoding, which can be input by separately hitting the vocoding code. This is different from Chinese Pinyin. Although the initials of Chinese Pinyin have fixed pronunciations, it is for the convenience of communication. The initials that are not pronounced or pronounced can read the sounds, and cannot separate the Chinese characters. .

 2. Key code and fingering

 The key codes used by the vocoding are mainly "X", "B", "D", "Z", "G", and the individual vocodes use "I" and "U", which are arranged in front. Key code. The key code that constitutes the vocoding is mainly hit by the thumb and forefinger, and the vocal code uses the middle finger.

 For its rhyme code, the key codes used are "I", "U", "N", "E", "A",

"0", relative to the vocoding, the sequence of these key codes is backward, in line with the Chinese Pinyin initials, the finals of the finals. The key code that constitutes the rhyme code is hit by the middle finger, the ring finger, and the little finger, and the most frequently used middle finger is used most frequently.

 Multi-button parallel principle of speed recorder

 All the key codes that make up each code are required and can be pressed and clicked with one touch of a single hand, instead of hitting each key in turn like a standard keyboard. This is the "multiple button" of the deck. And the "principle" is also the basis for its distinctive fingering and high-speed hitting.

However, it can be seen that in order to quickly enter, the speed recorder keyboard needs to mobilize all the fingers to reduce the flexibility of the operation, and also limits the further miniaturization of the keyboard size. Moreover, by analyzing the above-mentioned speed recorder keyboard, although it can input characters more efficiently and quickly than the traditional keyboard, the keystrokes can be completed by double-clicking with both hands, but due to the buttons The arrangement is more monotonous, and there are defects in erroneous operation and inconvenient operation as well as rapid input requiring long training. Summary of the invention

 To this end, the present invention proposes a novel information input device which has a smaller number of keys and size and greater flexibility than a prior art keyboard, and can input more information.

 According to the keyboard implemented by the present invention, on the basis of multi-key hitting, all combinations of up to 5- 7 buttons can be simultaneously operated with one finger, and the moving range of the finger is extremely small, and the error is greatly reduced.

 Moreover, in accordance with the keyboard of the present invention, the present invention adopts a novel Chinese pinyin initial and vowel layout, that is, code bit mapping, thereby making it easier to memorize the key code to further increase the input speed.

 According to an aspect of the invention, there is provided an information input device comprising an electronic circuit and at least one set of input units, each set of input units comprising a first switch, a second switch, a third switch and a fourth switch, wherein the electronic circuit The switch state is detected, characterized in that the four switches are arranged such that any combination of the switches can be simultaneously triggered by a single finger.

It can be seen that in the existing keyboard, basically one finger operates a key, and at most one finger operates two keys at the same time, and outputs one character or at most four characters, so that one finger operation outputs less characters. The amount of memory is not much, so the combination of each button and their order are not very important. However, the keyboard of the present invention can operate five buttons at the same time, and the output characters are 2 ⁵ = 32. The combination of the keys and their order are very important, otherwise it will be very difficult to remember, which is also The biggest difference between the existing keyboards, the existing keyboard does not need to consider this problem. Although we can freely define a key combination for a character or code, the scheme with very small memory or no memory is undoubtedly the most popular among users.

 The implementation keyboard according to the present invention has the following features:

 1, using multiple keys and hit.

 2. One finger can easily operate up to 5-7 keys in all combinations.

 3. The movement range of the finger is extremely small.

 4. All character input (including Chinese), function keys, and combination keys are all keystrokes input.

5. The correspondence between key combinations and characters is very regular, no special memory is required.

 6, the volume is very small, can achieve 2cm X 2cm square without affecting the input speed.

 7. There are very few buttons. The Chinese all-in-one input requires only 12 buttons, which can be compressed to 11 buttons. Without the button input, only 10 buttons can be used, which can be compressed to 9 buttons. English capitalization, 10 Arabic numerals and decimal point input require only 6 keys.

 8, easy to operate, no special training.

 9. The number of fingers required to participate is very small. It takes only 3 fingers to input all the Chinese characters. If you use the sensor to input the tone, you only need 2 fingers. You only need one finger to input common symbols such as English (upper and lower case).

10, the traditional keyboard is to use the finger to operate, the new keyboard in addition to the finger, palm, boxing, feet can be With a convenient operation, there is only a slight difference between the input speed of the finger and the handicapped.

11, an input unit can be designed into 6 keys, the basic unit of Braille is 6 black dots, the number is consistent with the science of coding, making it easy for blind people to use the new keyboard. DRAWINGS

 Before describing the present invention, it is specifically noted that the term "key" or "key" in the present invention actually means a switch having two states, a trigger and an untrigger. However, the "simultaneous" concept used in the present invention can be understood as both absolute (ie, no time difference, completed at the same time), but it is also possible to set two actions that occur within a predetermined time range as needed. The work is "simultaneous", as can be assumed that the two actions completed within 100ms also occur "simultaneously". Additionally, although the term "keyboard" is used in this application, it should be understood to mean all means available for inputting information.

 [Embodiment 1]

 As shown in Fig. 1, a top view of a keyboard 100 in accordance with a first embodiment of the present invention is shown.

 The keyboard 100 is composed of a base 10 and a first key 1 having a concave shape, a second rectangular key 2, a concave third key 3, and a rectangular fourth key 4 on the same surface of the base. The two arms 1a and 1b of the first button are opposite to and spaced apart from the two arms 2a and 2b of the third button, wherein the distance can be as small as possible, as long as they do not interfere with each other, and the second and fourth keys are at The distance between the first and third keys and the distance between the three inner sides of the first and third keys may be as small as possible, as long as they do not interfere with each other.

The advantage of the keyboard structure thus set is that its volume can be very small, for example, it can be 2 _Cm x 2 _cm . When held in the hand, for example, with only a thumb, the four keys can be operated extremely conveniently, and the occurrence of a false probability can be reduced. We know that, in the arrangement rule of combination, a total of four keys 2 arranged in ^four combinations, i.e. 1, 2, 3, 4, 12, 13, 14, 23, 24, 34, 123, 124, 134, 234, 1234, 0 (empty, ie no button, no output). Where 1 represents the first input key 1, and so on; 12 represents the first and second input key combinations, and so on; 123 represents the first, second, and third key combinations, and so on and 1234 represents the first and second , three, four key combinations and 0 means no health operation.

 The present invention adopts the geometrical multiple growth rule of these permutations and combinations, and proposes a novel keyboard structure, that is, the method of simultaneously pressing a combination key to input information.

 The following uses the numbers 0-9 as an example to illustrate, see Table 1.

 In Table 1, the numbers 0-9 to be entered are shown in hatching, and the corresponding key codes are shown in the next line next to it. As can be seen from the table, press the first, second, third, and fourth keys to output the numbers 1, 2, 3, and 4 respectively; press the first and second combination keys simultaneously to enter the number 5 and press the second The three combination keys can input the number 6. Press the third and fourth combination keys at the same time to input the number 7. Press the fourth and a combination keys simultaneously to enter the number 8. Press the first, second and third combination keys simultaneously to enter The number 9, press the third, fourth, and a combination of keys at the same time to enter the number 0. Therefore, the present invention can input at least 10 characters with only four buttons. Compared to prior art keyboards, you can save at least 10 buttons of space. The special keyboard of the present invention is particularly suitable for applications where input numbers are dominant, such as cell phones, cash registers, and the like. Take a mobile phone as an example. As can be seen from the table, there are still five unused code bits formed by the above four keyboards. Therefore, in the case where the above other code bits are used to input corresponding numbers, the code bits 234 and 124 can be used to indicate 幵/OFF. The key and the on/off button are indicated by "13" for "*", 24 for "#", and the code bit "1234" is reserved.

 Thus, the keyboard and its operation mode according to the present invention can be sufficiently applied to mobile phones, cash registers, and the like.

Mechanical, electrical or software implementations of the various keys of the present invention will be apparent to those skilled in the art. For example, the buttons of the existing common keyboard, or the buttons of the mobile phone, and other forms such as a touch switch or a touch screen and related circuits are combined with the corresponding input method software. An example of a circuit that can be used in the present invention is described below with a 4-16 decoder, as shown in FIG. The four output status lines corresponding to the four buttons are respectively connected to a common decoder 20 for identifying the key press status. For example, when the second and third keys are pressed simultaneously, the decoder 20 strobes the 6th line (i.e., the 6th line outputs a high level). When the controller in the phone detects that line 6 is high, the number "6" is displayed on the display. By the same token, when the second, third, and fourth keys are pressed, for example, the line lj line is strobed. The phone number entered by the user is sent when the controller detects that line 14 is output high.

 Alternatively, the signal output states of the corresponding four keys may also be detected by software programming or a scanning circuit commonly used in prior art keyboards, the principle of which is similar to that of the above decoder. For example, when it is detected that the signal output corresponding to the second and third keys becomes a high level, it is considered that the second and third keys are simultaneously pressed, and therefore, the number "6" is output.

 In addition, the applicant needs to point out that the code position arrangement corresponding to the four keys of the present invention may be arbitrary, and the arrangement manner in the above Table 1 is only convenient for memory, non-limiting and necessary. Obviously, for example, the code bits of the second line can be interchanged with the code bits of the fourth line, so that the first, second, third, and fourth keys can be respectively pressed to respectively output the numbers 5, 6, 7, and 8; One or two combination keys can output the number 1, press the second and third combination keys to output the number 2, press the third and fourth combination keys to output the number 3, press the fourth and a combination of keys to output the number. 4.

 In addition, the related circuit such as the decoder mentioned in the present invention can be fabricated together with the keyboard, that is, packaged in the pedestal, but it is obvious that the decoder or the like can also be disposed separately from the keyboard, such as It is placed in a host computer connected to the keyboard, such as a computer or any other processing device, and the keyboard only needs to provide a signal line corresponding to the state of the button. The resulting keyboard will be smaller and lighter.

 Optionally, as shown in FIG. 3, the shape of the second and fourth keys may be a circle or other shape, and the first and third keys are partially arc-shaped, wherein the arc key 1 and the arc key The two end portions of 3 are kept at a certain distance so that they do not interfere with each other.

 Similarly, multiple circuit contacts can be set under the arc keys 1 and 3 shown in Fig. 4 to increase the sensitivity of the button.

 Additionally, although the preferred keyboard layout of the present invention is illustrated in Figures 1 and 3. However, it will be apparent to those skilled in the art that it is also possible to use an arbitrarily arranged keyboard in the present invention as long as the output states corresponding to the buttons are simultaneously monitored.

 [Embodiment 2]

In the embodiment, the working processes of the first, second, third, and fourth keys are the same as those in the first embodiment, except that the positional relationship of the keys is in the foregoing position. As shown in FIG. 4, wherein the first, second, and third keys are fan-shaped keys arranged in the circumferential direction (of course, not limited to the sector keys), and the fourth key is a ring surrounding the one, two, and three keys. Keys, these keys are separated from each other by a certain distance so that they do not interfere with each other. The keyboard The advantage is that it is very convenient for single-finger operation, and the probability of mis-pressing is lower.

 [Embodiment 3]

 A keyboard structure according to a third embodiment of the present invention is shown in FIG.

 The first, second, third, and fourth keys 1, 2, 3, and 4 are arranged in a matrix form in a counterclockwise direction, and are spaced apart from each other by a certain distance. And setting a further first input key 外侧 at a predetermined distance outside the second and third keys, so that a single finger simultaneously triggers the first, third combination keys or the first, second, and third combination keys; similarly, Providing another second input key 2 outside the third and fourth keys and at a distance, so that a single finger simultaneously triggers the second, fourth combination key or the second, third, and fourth combination keys; a third button 3' is disposed on the outer side of the first and fourth keys at a distance, so that a single finger simultaneously triggers the first, third, or first, third, and fourth combination keys; and at the first and second keys Another fourth button is disposed on the outside and at a distance to facilitate the simultaneous triggering of the second, fourth, or first, second, and fourth combination keys by a single finger.

 The relationship between the key and 1 is shown in Fig. 6. As can be seen from the figure, when Γ is pressed, it is equivalent to the key 1 being pressed, so that the same pad signal is also output from the output line 0UT1. Similarly, when 2 is pressed, it is equivalent to the key 2 being pressed, so that the same code bit signal is also output from the output line OUT2; when T is pressed, it is equivalent to the key 3 being pressed, so also from The output line OUT3 outputs an identical pad signal; when 4' is pressed, it is equivalent to the button 4 being pressed, so that the same pad signal is also output from the output line OUT4.

 Similarly, the above key arrangement has the advantage that the false press rate can be effectively reduced. Otherwise, if the keys, 2 ', 3', 4' are not set, when the user needs to press the keys 2, 4 at the same time, since they are at a diagonal State, when using single-finger operation, it will easily trigger key 1 or 3, if necessary, use another finger; and when setting keys Γ, 2', 3', 4', due to the equivalence of the keys, you can use only Accurate input by one finger.

 In addition, with the key 1, as an example, from the equivalence of the above-mentioned keys 1, V, it is also possible to integrate the keys 1, 1 ' as a whole, so that the keys 1, Γ are linked, and then press When the down button is pressed, the button under button 1 is also triggered.

 [Embodiment 4]

Compared with the keyboard in the foregoing Embodiments 1 to 3, the keyboard in the embodiment of the present invention further adds a fifth key on the basis of the foregoing keyboard layout, and sets the fifth key in the first, second, and third Below the four keys, they are hidden under these keys, not on the same surface or other side surfaces as these keys. The advantage of this is that when any one of the first to fourth keys is pressed "forcedly", the fifth key located below can be triggered at the same time, thereby achieving the purpose of one hit double. Here, 1, 2, 3, four buttons form a basic button unit, and the fifth button is a force switch. It can be seen from the above that with the keyboard of the present invention, one finger, such as a thumb, can manipulate up to five buttons, thereby greatly simplifying the use of the keyboard while Stay productive.

 The five keys according to this embodiment can be implemented as follows. As shown in FIG. 7, the figure shows a cross-sectional view along the AA' direction of FIG. 1 when the fifth key is placed under the button of Embodiment 1, and the first to fourth switches are disposed on the surface plate 0_0' of the pedestal. The fifth switch is disposed under the surface plate. When the first to fourth switches or the surface plate are pressed hard, the surface plate is deflected downward to trigger the fifth switch.

 In addition, optionally, the first, second, third, and fourth keys 1, 2, 3, 4 may be composed of a touch switch or a touch screen material, and the fifth unit is composed of at least one of a touch switch or a touch screen. The pressure detecting device is configured to be distributed under the first to fourth keypads and under the touch or touch screen independent of the first to fourth keypads (to be used to individually trigger the fifth button). The advantage of adopting this technical solution is that the operation is more convenient. The user does not need to "force" to press the first and fourth units to trigger the corresponding keys or their combination keys; and when the "force" is pressed, the fifth key and the combination of the above keys and their combination keys can be triggered simultaneously. key.

 Such a pressure detecting device may be a mechanical switch, a pressure sensor, a proximity sensor, a contact sensor or a magnetic sensor.

It can be seen from the foregoing that the five-key input device obtained according to the embodiment of the present invention can input up to 2 ⁵ - 1 = 31 information symbols. As an application, for example, we know that there are 26 letters in English or French, so the keyboard according to the present embodiment is sufficient to input 26 English or French uppercase or lowercase letters and related symbols such as commas, periods, question marks, and the like.

 Table 2 below shows an example of the use of the keyboard to input English lowercase letters - Table 2

The keyboard according to the present invention is particularly suitable for use in English or French input situations where attention is not required, such as shorthand. As described above, when the fifth key is not set separately, if it is desired to input "?", it can be realized, for example, by setting the first, third, and fifth keys simultaneously by program setting.

In this embodiment, although the fifth key is placed under the first to fourth keys, it is conceivable by those skilled in the art that an optoelectronic (or ultrasonic, capacitive) detecting device placed above the four may be used. In the implementation, when it is required to trigger the fifth button, that is, the photodetection device, the photodetection device and the first to fourth keys are simultaneously triggered within a predetermined time. [Example 5]

 In the fifth embodiment of the present invention, a sixth key 6 is added on the basis of the fourth embodiment. The sixth button may be disposed on a side of the base perpendicular to the surface of the first to fourth keys, so that the first and fourth keys do not interfere with each other during one-hand operation, and facilitate the removal of the thumb. Other finger manipulations, at this time, the sixth button can use ordinary buttons.

 Obviously, it is of course also possible to place the sixth key at any other position as long as it does not interfere with the operation of the first and fifth keys.

 According to the keyboard of the present invention, English or French letters and other characters including upper and lower case can be completely input. Table 3 below lists the correspondence between the key combination of the keyboard and the English uppercase and lowercase letters and numbers.

For the input of English uppercase and lowercase letters and Arabic numerals, since the input unit has 6 keys, its combination has 2 ⁶ = 64, minus the null press (cannot input any characters), a 64 - 1 = 63 code bits, and 26 (lowercase) + 26 (uppercase) + 10 (number) + 1 (decimal point) = 63 The number is just right. The combination of 4 buttons is also divided into 4 groups. The first group to the third group are all used to input English letters. The combination of the 4 keys in the fourth group is also used to input English letters. The rest is used to input Arabic numerals and Decimal point. Please refer to the table for the specific correspondence.

Table 3 English uppercase and lowercase letters and numbers

/u/ iiislud/ O.89SAV

The even rows represent the code bits. When there are multiple code bits, such as the first column "561" in the last row, it means that the first, fifth and sixth keys are pressed simultaneously.

 It can be seen that with only one keyboard with six keys, all the English letters and numbers can be fully expressed and the input efficiency is high, the operation is simple, and two fingers such as the thumb and the index finger can be used with only one hand. You can enter English in its entirety. For a traditional 101 keyboard, at least 10+26+1=37 keys are required to complete, and almost ten fingers are required for fast input.

 Optionally, the sixth key 6 in this embodiment may not appear in the form of a button, but a tilt sensor installed in the base or wearing a finger, for example, when a capital letter or a part of a number needs to be input, the base may be used. The seat or finger is rotated by a predetermined angle to effect a trigger corresponding to the sixth key 6.

[Embodiment 6]

 In the present embodiment, the present invention proposes an input keyboard for inputting Chinese characters in accordance with pinyin, the input keyboard being composed of two sets of input units, wherein each set of input units includes five keys constructed in accordance with the foregoing embodiments. The first set of input units is used to input the initials, and the second input unit is used to input the finals. For convenience of explanation, the fifth button in the first group of input units is also referred to as an "L" button, and the fifth button in the second group of input units is also referred to as an "R" button.

 In view of the large and difficult to remember features of Chinese Pinyin, in the present invention, the Applicant combines the unique features of the keyboard of the present invention to rearrange the existing initials and finals for learning, thereby enabling the keyboard incorporating the present invention. It is relatively simple to remember the initials and finals, and thus improve the efficiency of Chinese input, as explained below.

 Rearrange the initials and finals in the Xinhua Dictionary

 Let's first look at the initials in the Chinese Pinyin program in the Xinhua Dictionary.

It has three rows and eight columns, the first line of 8 consonants, the second line of 6 consonants, the third line of 7 consonants a total of 21 consonants. If we take the initial r out of the third line, the three-line initials have a symmetrical relationship. Since the finals can form a single syllable separately, we use the initials as the initials when the finals form the syllables. The syllables of a, o, and e share the initials 3. Add a line to the initials in the Xinhua Dictionary ( The fourth line), put &, r, w, y into this line, constitute a new matrix of four rows and eight columns. This initial table has one main feature: the initials of the first to third lines are symmetrical about the fifth line center. The main purpose of this is to make the initial and the new keyboard form a very regular, memory-free mapping. The correspondence between the key combination of the keyboard and the initial

 The first three lines of the new initials are symmetrical, and there are 4 3 3 symmetry in quantity. We can see 4 key combinations of the keyboard, 6 combinations of 2 keys, which can be assigned 4 3 3 in number, corresponding to the initials on the left of the new initial table, plus an easy-to-trigger fifth switch "L". It can correspond to the initials on the right side of the new initials, and the remaining four initials correspond to the combination of three keys. The key combination and arrangement of the keyboard and the arrangement of the initials on the initial table form a very regular, one-to-one mapping relationship. Table 4

 The mapping between the new initials and the code bits of the keys in the first input unit

Let’s look at the vowel table iu 0 in the Xinhua Dictionary.

 0 uo

 E ie Qe

 Ai uai

 Ei uei

 Ao iao

 Ou iou

 An ian uan Uan

 Eng ing ueng

Ong iong It seems messy and memory is harder. There are 12 finals in the first column, five starting with a, three starting with 0, and four starting with e. First look at its letter composition: 1 letter consists of 3 (a, o, e each), 2 letters consisting of 6 (a beginning of 3, o at the beginning of 1, e beginning 2 There are three of the three letters (one each at the beginning of a, o, and e). That is to say, the finals starting with (a, o, e) are not evenly distributed in quantity. But by careful observation, one letter and three letters are very regular (a, o, e), (ang, ong, eng), then look at the two letters to form the final, starting with a and starting with e There is also a regular (ai, an), (ei, en) but an ao starting with a. There is a letter o in ao, and the vowel of two letters starting with 0 has only one ou. If we classify the final ao to the final vowel with 0, it is also regarded as the final vowel with 0, then &, o, e vowel beginning equal in number to the beginning a 4, 4 0 at the beginning, the beginning of the e 4, wherein a and _e vowels very regular letters, are a, and e (i, n, ng) The combination of the two letters formed by the initial vowel of 0 does not conform to this rule. In the order of 8, o, e and the order of one letter, two letters, three letters, the whole vowel table has more regularity. The combination of the vowels and the arrangement of the vowels are very regular, and the memory is easy. too much.

 The correspondence between the key combination of the keyboard and the final

The two rows of the new vowel table are symmetrical in number 16 and 16 in total, 32 in total. The four buttons of the keyboard have 16 combinations and one easy-to-trigger fifth switch "R" has 32 combinations, which just meets the requirements in quantity. We first divide the combination of 4 buttons into 4 groups, the combination of 1 button is the first group, and the combination of 2 button numbers is adjacent (41, 12, 23, 34 Note: 41 is the end-to-end connection in the serial number chain , as the serial number is adjacent) for the second group, the combination of the three buttons is the third group, the empty button (the four buttons are not pressed), the two buttons, the combination of the two button numbers (13, 24), One of the four button combinations is the fourth group. According to the order of grouping, a one-to-one mapping relationship is formed with the finals of the first line of the new final table. The above-mentioned button combination plus the fifth switch forms a one-to-one mapping relationship with the finals of the second line of the new final table, see Table 5 below.

After the above processing, not only the initials and the finals are arranged regularly, but also the number and order of the key combinations and the initials, the number of letters of the finals, and the order are regular. For example:

Initial part: The combination of one key corresponds to the initial (b, p, m, f, d, t, n, 1), and the combination of the two keys corresponds (g, k, h, j, q, x, zh, ch , sh, z, c, s), the combination of the three keys (aoe, r, _w , y) ₀ final part: 1 key combination (the first group) corresponds to the initials of a (a, ai, an, Ang, ia, iai (i), ian, iang), 2 key combinations (the second group) correspond to the initials of o (o, ou, ao, ong, io (u), iou, iao, iong), 3 The key combination (the third group) corresponds to the finals of e (e, ei, en, eng, ie, iei, in, ing), and the fourth group corresponds to the finals of u (ua, uai> uan, uang, ue, Ui, un, uo).

Note: Special vowel processing: There are more than 32 vowels in the Xinhua Dictionary. Since 26 English letters are not flawed, we use V instead of ίί, and most Pinyin input methods do the same. The vowel of the ΐί line, when there is no vowel in front, is written as yu (迂), yue (about), yuan (冤), yun (halo), the two points of iLh are omitted, and the letter ^ is followed by the initials j, q, x The two points on the 也 are also omitted and become the letter u. But when you fight with n, 1 can't be omitted, then replace it with the letter V. Therefore, when encountering the initial n, 1, as a special case special treatment, nv, lv because the initials ^ 1 have no nui, lui, so the final V is placed in the ui position, nve, lve also because the initial n, 1 does not have nue, Lue, so the final ve is placed in the ue position. Since ve is similar to ue reading, it doesn't need to be memorized. Just remember the two syllables, nv and lv. The finals er are not in the 32 finals, but the finals can not form the syllables separately, so in the zero initials ( _aoe ) the finals ong become the finals er, the finals ueng and the initials (bpmfdtnlgkhjqx zh ch sh zcsr) in the "Xinhua Dictionary" When any syllable is formed, when syllables are formed separately, u is written as w and becomes weng. It can be seen that there is no vowel of ueng in the commonly used syllables. Put uo in this position in the new vowel table. The symmetry of the two lines is very symmetrical. It is obvious that all the syllables in the <Xinhua Dictionary> have a unique correspondence in the keyboard. More than 420 Pinyin syllables only have nv, lv, er. These three syllables need to be memorized, and the amount of memory is greatly reduced compared with the original. It can even be said that in many languages of the world, only the syllables of Chinese Pinyin are so regular, learning The difficulty of Chinese Pinyin is greatly reduced.

 Therefore, the keyboard composed of the above code bits can easily input Chinese characters by pinyin, and the Chinese character input can be realized by switching to the Pinyin Chinese character input method without the prior art.

In addition, it is to be noted here that although in the present embodiment, two sets of input units are respectively used for the input of the initials and the finals in the Chinese pinyin, considering the current, for example, the double spell input method, each of the finals is composed of each In other words, the present invention can also use only one input unit and the input unit includes at least five key switches to perform the Chinese input method, and is almost the same as the ordinary Chinese double spell input method. For example, referring to Table 4, the key code '13' indicates the initial 'h', but the key code '13 can also be set to indicate the final 'ang'. Therefore, when the user wants to input the Chinese character 'voyage', he You can press the first and third keys at the same time to input the initial “h”, then press the first and third keys again to enter the final.

"ang", from which you can enter Chinese characters pronounced 'hang'.

 In fact, any input method in the prior art can be combined with the keyboard of the present invention for the purpose of inputting Chinese characters at high speed on a super-miniature keyboard.

 [Embodiment 7]

The present embodiment is similar to the sixth embodiment in that the mapping relationship between the code points of the same new initial table and each key in the first input unit and the mapping relationship between the new final table and the keys in the second input unit are used. The difference is that each input unit further includes a sixth key, that is, each input unit includes the key structure disclosed in Embodiment 5. To facilitate the description in conjunction with its function to be described below, the sixth key in the first input unit is now referred to as "Id" and the sixth key in the second input unit is referred to as "rd". Since Chinese Pinyin has four tones, the present invention reduces the repetitive code of pinyin by providing two tone switches ld, rd; and in the case of speech synthesis, setting these two tone switches facilitates correct speech output. It can be seen that 12 keys have code bits 2 ¹² = 4096, and Chinese pinyin bands occupy 24 X 32 X 4 = 3072 code bits. Therefore, the present invention realizes more accurate pinyin by using a 12-key keyboard. Input.

 Further, the sixth health in the present embodiment can be replaced with a tilt sensor to select a tone for outputting a desired Hanyu pinyin according to the rotation of the hand holding the keyboard. This speeds up the input speed of Chinese characters without increasing the burden on the fingers.

In addition, as a variation of the embodiment, the keyboard of the present invention can also be configured as three input units, B, C, wherein the number of buttons (or the number of equivalent buttons) is preferred in Chinese and English: 5 keys / per input Unit, Pinyin input requires two input units A, B, and C unit consists of two buttons "ld", "rd" for inputting tones. Thus, the keyboard combination is divided into three parts A unit (consonant), B unit (final), and C unit (tone), wherein the unit A has 2 ⁵ = 32 code bits, and the B unit has 2 ⁵ = 32 code bits. The C unit has 2 ² = 4 code bits, and the three unit combinations have a total of 32 X 32 x 4 = 4096 code bits. The pinyin band needs: 24 X 32 X 4 = 3072 code points. For the traditional 101 keyboard required code points:

 English capitalization required: 2 X 26 = 52 code points

 Arabic numerals need - 1 X 10 = 10 code points

 Common function keys need: 1 X 15 = 15 code points

 Chinese punctuation marks need: 1 X 32 = 32 code bits

 English punctuation needs - 1 X 32 = 32 code bits

 F1~F12 need: 1 X 12 = 12 code bits

 Shift Ctrl Alt requires: 1 x 3= 3 code points

 Shift Ctrl Alt combination requires 8 code points and 26

The letter combination needs to be: ' 8 X 26 = 208: Therefore, in order to complete the above information input, a total of: 3072 + 52 + 10 + 15 + 32 + 32 + 12 + 3 + 208 == 3436 code bits.

 Remaining: 4096 — 3436 = 660 code points

 (Note: Since the new keyboard does not need to press the upshift key or the uppercase lock key in mixed case input, the Caps Lock key is no longer needed.)

 It can be seen that using such a keyboard combination to input Chinese and English, Arabic numerals, Chinese and English punctuation, common function keys, and common key combinations are one keystroke input, no need to switch, so it can completely replace the traditional PC keyboard, which greatly facilitates the user. .

 When using such a keyboard combination for Chinese and English input, one finger can be used to control the A unit, one finger controls the B unit, and one finger controls the C unit.

 The characteristics of inputting pinyin and Chinese punctuation are: A, B, C are used in all three units. Only when the rhyme is ua is a special case, and B unit is not used (empty press).

 The characteristics of inputting English case and number plus a decimal point are: B unit plus the first key of C unit, A unit is pressed empty.

 The input function keys are characterized by: B unit plus the second key of the C unit, and the A unit is pressed empty.

 The characteristics of inputting English punctuation marks are as follows: The first and second keys of the B unit plus the C unit are pressed, and the A unit is pressed.

 The main feature of inputting English capitalization and numbers plus a decimal point, function keys, and English punctuation marks is that B unit plus C unit can be used. A unit does not need to move, and the boundary with Chinese is very clear.

 The input characteristics of the key combination are: A, B, C are used in all three units. Since the 24 code pinyin initials of the A unit are occupied, the remaining code bits of the A unit can be solved by adding the B unit and the C unit.

 In addition, it should be specially pointed out that the above is to input with three fingers of one hand in general, and in some occasions requiring high-speed input, three identical input units can be added for the other hand to operate. With two hands in one input, you can input two syllables at a time, and the speed is doubled.

 Pinyin code selection problem

 In view of the characteristics of Chinese Pinyin, that is, there may be multiple Chinese characters under the same pinyin. The traditional keyboard can only use Arabic numerals or several punctuation keys to select words. 26-key keys cannot be used for word selection, otherwise it will appear. Logical confusion. However, the new keyboard can be used to select a lot of characters. Since the new keyboard does not need to be switched when inputting Chinese and English, when there are Chinese characters in the candidate window of the input method software, the uppercase and lowercase letters of the English or Arabic numerals can be used to select the words. For example, if the input Chinese character pinyin is "tian", then the corresponding Chinese character appearing on the screen is "1 day 2 add 3 fields 4 sweet", then the predetermined digital code bit in the second input unit can be used to select The desired Chinese characters, such as when you want to select "Field", can directly select the "513" code position (ie, the first, second, and fifth keys) of the second input unit.

In addition, it should be particularly pointed out that the keyboard of the present invention is inserted in Chinese with pinyin and English letters and The key arrangement at the time of the number is not limited to the above-described preferred embodiments of the present invention, and the correspondence between the respective key bits and the input information can be freely defined in a specific application.

 [Embodiment 8]

According to the above embodiments, according to the concept of the present invention, different types of input devices including different input unit numbers and each input unit including different input keys can be designed according to different application requirements. For example, the new keyboard proposed in this embodiment is composed of 7 keys, wherein the first and fifth keys can be arranged in any of the foregoing manners, and the sixth and seventh keys are arranged to be separated from the key base, such as wearable. On the same finger or stylus that operates the first and fifth keys, the two input keys may be, for example, a tilt sensor, which can be given when the finger is horizontal, left, right, forward or backward. All four combinations of buttons, and one of the four states of the thumb to operate the keyboard of five buttons to achieve a finger operation of all combinations of seven buttons, however, by wired or wireless with the input Electronic circuit communication in the device, such wireless mode can be infrared, radio frequency, Bluetooth, and the like. Since the seven buttons can generate 2 ⁷ - 1 = 127 key code, the Chinese pinyin input requires 24 (consonant) +32 (final) = 56 code bits, plus the English capitalization and 62 required for digital input. The code position, therefore, the 7-key keyboard implemented according to the embodiment can be operated in a single finger operation (ie, the trigger switch corresponding to the sixth or seventh keys is worn on the same finger that operates the first-fifth key switch) or at most two fingers operation (In other words, the trigger switch corresponding to the sixth and seventh keys is worn on a different finger from the first to fifth key switches), thereby inputting text information, thereby greatly increasing the input speed.

 [Embodiment 9]

 The novel keyboard according to the present embodiment includes four pairs of light emitting-receiving devices, as shown in Fig. 8, which is an enlarged schematic view in which the first light emitter 1a is emitted and received by the first light receiver lb. The light 1 is used as a first input switch, and the light 2 emitted by the second light emitter 2a and received by the second light receiver 2b serves as a second input switch, which is emitted by the third light emitter 3a and is used by the third light receiver 3b. The received light 3 serves as a third input switch, and the light 4 emitted by the fourth light emitter 4a and received by the fourth light receiver 4b serves as a fourth input switch. As shown in Fig. 8, A23 indicates the intersection of ray 2 and 3, and A24 indicates the intersection of ray 2 and 4. Take the second light as an example. When the finger is placed in the area A1 or A2, the external light line received by the second receiver 2b is blocked, whereby the second switch can be triggered by determining the output state of the receiver 2b; When it is near A23, the light rays 2, 3 received by the receivers 2b and 3b can be blocked at the same time, thereby judging that the second and third switches are simultaneously triggered. Similarly, when it is desired to simultaneously trigger the 2nd, 3rd, and 4th switches, the A23 and A24 regions can be simultaneously covered by a single finger, thereby simultaneously blocking the light received by the receivers 2b, 3b, 4b, and thus triggering the switches 2, 3 , 4.

 The input device implemented according to this embodiment is simpler and more sensitive in structure. And for example, the number of keyboards can be increased by paralleling the plane formed by the four light rays and placing a fifth key below the plane. The fifth key can be, for example, a touch switch or a touch screen.

[Embodiment 10] In the embodiment, a computer system is proposed, which uses the keyboards of the sixth and seventh embodiments to input English or Chinese characters and English. The computer system comprises: a keyboard, a display; a character library for storing various characters such as Chinese characters; and a coding controller, which detects the state of each key from the keyboard and generates a final input coded signal, And display the desired character by retrieving, for example, a character library.

 In addition to the above computer system, the keyboard of the present invention is also particularly suitable for all applications that require input of information, such as cash registers, speed recorders, typewriters, and the like that require information to be entered.

 The computer system may further include a speech synthesizer, and since the keyboard according to the present invention can input pinyin in the tune, the text input by the user can be accurately played by the speech synthesizer.

 In addition, a processor and a speech synthesizer can be integrated in the keyboard of the present invention to form an independent player, which is particularly suitable for use in squatting, dumb, and blind people. The player turns the text input thereto into a sound to the normal person. Variant

 The invention can also be modified on the basis of the above embodiments. As shown in Figs. 10A - 10C, five-key keyboards 100 and 100' and a six-key keyboard 101 are shown, wherein reference numerals 1-6 denote respective opening keys. However, unlike the previous embodiment, the other keys 1-4 are circumferential with respect to the key 5. In the keyboard 101, the sixth key can be placed at any position, preferably outside the key 1 or under the keys 1-5. When the finger acts on both the key 5 and other key areas, for example, on the key '514', the three keys can still be triggered at the same time. In a specific implementation, the person skilled in the art can carry out such a design according to the known technology, for example, the key 5 is a mechanical key, and the keys 1, 2, 3, 4, 6 are designed for the touch screen structure or hidden in the same as the key 5. Mechanical keys under the surface of the surface, etc.

 In order to cooperate with the above key input, the device features are convenient for inputting information, and the corresponding key position is set corresponding to the information to be input, as will be described below.

 First, the above 5-key keyboard 100 and 100' and 6-key keyboard 101 can be used in place of the 4-key keyboard mentioned in the previous embodiment to facilitate finger input. Thus, the following correspondence relationship can be employed to set the code position of the keyboard.

 As can be seen from the above table, compared with the aforementioned 4-key keyboard, the use of the 5-key keyboard 100, 101 ' here, the situation of three or more combination keys operated by a single finger is greatly reduced, only three, so More convenient for finger operation.

 For the case of inputting English letters, in the case of a six-key keyboard 101, the correspondence between each switch code bit and the output English letter is:

Wherein "丄", " ₂ ,,""3","4","5","6" represent the first, second, third, fourth, fifth and sixth switches, respectively, and their corresponding combinations The representative presses the corresponding switches at the same time.

Based on the above six-key keyboard 101, the seventh key can be further added to further expand the key of the present invention. The input function of the disc. For example, by adding an English uppercase and lowercase letter, the corresponding relationship is as follows:

 "7" indicates the seventh switch. The seventh opening key here may be disposed under the first to fifth opening keys and below the first to sixth opening keys, and the seventh may be triggered simultaneously by forcibly triggering at least one of the first to sixth keys key.

 In addition, an eighth switch key is further included, and the switch is located at any position other than the above-mentioned switch positions, so as to facilitate finger operations other than the single finger of the above six keys, for being combined with other switches. Encoded to output a predetermined 127 characters.

 In addition, a ninth switch is included, the switch being located at any position other than the above-mentioned switch positions, so as to facilitate finger operations other than a single finger operating the above six keys, for being combined with other switches. A predetermined 127 characters are output. Preferably, the ninth switch and the eighth switch are located on the same surface perpendicular to the surface of the base to facilitate other finger operations.

In addition, the six-key keyboard 101 according to the embodiment can also form two sets of input units, and can input Chinese characters in the form of Chinese Pinyin, wherein six switches in the input unit of the first group are used to input the initials of the Chinese pinyin, and the second The six switches of the input unit are used to input the finals of the Hanyu Pinyin. The correspondence between each switch code bit and pinyin is - For the first set of input units:

 Where "L" represents the sixth switch of the set of input units on the left hand side; for the second set of input units,

 Where "R" represents the sixth switch of the set of input units on the right hand side.

It can be seen from the above modification that the same amount of information can be input by setting a button with more than the minimum number of keys required, so as to facilitate single-finger operation, such as the five-key and six-key keyboard used above instead of the four-key keyboard. That's what it shows. Examples of this include: The seven-key keyboard obtained by the above embodiment is used to input English capitalization, and the code position correspondence is as follows:

 The correspondence between each switch code bit and the output English letter is -

The eight-key keyboard obtained by the above embodiment is used to input English letters and numbers. The correspondence between the common code bits and the characters is as follows: Character code bit Character code bit Character code bit Character code bit a 51 n 751 A 81 N 781 b 52 o 752 B 82 O 782 c 53 P 753 C 83 P 783 d 54 q 754 D 84 Q 784 e 512 r 7512 E 812 R 7812 f 523 s 7523 F 823 S 7823 g 534 t 7534 G 834 T 7834 h 514 u 7514 H 814 u 7814 i 5126 V 75126 I 8126 V 78126 j 5123 w 75123 J 8123 w 78123 k 5134 X 75134 K 8134 X 78134

 Wherein "R" represents the seventh switch of the set of input units on the right hand side; although the present invention discloses the above seven embodiments, it will be apparent to those skilled in the art that the present invention is not limited to the above embodiments, but may be combined with each other. Different embodiments and other variations are possible within the spirit of the invention. For example, the buttons of Embodiment 1 are mechanical, but there is no doubt that the keys can be implemented using touch switches or touch screen materials. For another example, the fourth ring-shaped key disclosed in FIG. 3 can also be hidden under the first, second, and third keys, that is, only three fan-shaped keys are disposed on the surface of the keyboard base, and the touch shown in Embodiment 4 is adopted. The switch or touch screen material plus the contact switch form implements the first to fourth keys. For another example, in the pinyin keyboard of the present invention, the first input unit may be provided with only five keys, and the second input unit may be provided with six keys. The same function can be accomplished without the tone input. Moreover, according to the design concept of the present invention, any number of input units and their input keys can be set according to the actual input information amount. In general, a mobile phone requires an input unit, two input units are required for Chinese and English input, and more than 20 input units are required for the keyboard and the like. For the convenience of a single finger operation, four keys or five keys are used as one input unit, and of course, more keys can be used. Moreover, although the above-described embodiments of the present invention are embodied in the form of an information input device, it is apparent that the device disclosed in the present application can also be used as a control device for outputting control information. Therefore, the scope of the invention is defined by the appended claims.
