Description

 Key shift type and input key shift input method

Technical field

 The present invention relates to the field of keyboard input technology, and in particular to a key shift type keyboard and an input method for applying a key shift type keyboard. Background technique

 With the development of science and technology, various smart devices and products (computers, mobile phones, numerical control devices, etc.) are widely used in real life. These smart devices and products require input commands through reliable and efficient human-computer interaction devices. The keyboard invented in the 17th century, because of its reliability and high efficiency, has always occupied an irreplaceable position in computer input devices. Especially since the invention of the computer in the 1940s, the keyboard has been widely used as a main computer input device. However, the current keyboard has obvious defects such as a large number of buttons, an influence on input efficiency, and a volume that cannot be reduced.

 Take the current 1 01, 104 standard computer keyboard as an example. The main input of the keyboard is uppercase and lowercase English characters, Arabic numerals, control symbols and so on. In order to realize the input of these characters, the current keyboard refers to the typewriter keyboard invented in the 21st century, and the buttons are arranged on the keyboard substrate in a certain manner. Since the keyboard keys are arranged in a plane, it is necessary to arrange so many buttons, and the required area is also inevitably large, which leads to three problems that cannot be solved by the long-term existence of the keyboard:

 First, it seriously affects the typing efficiency, and the typing efficiency has reached the limit.

 Due to the large number of keyboard buttons at present, most people need to find the letter button when they are typing, and then the finger hangs on the keyboard to move up and down and left and right to find the button before pressing the typing, unless it is professionally trained to use "blind". With this type of input, the range of motion of the hand is large, and even after professional training, the typing speed has reached the limit.

 Second, the long-term suspension of typing causes muscle fatigue and injury

 In addition, since the hand is suspended on the keyboard, the fatigue of the wrist when inputting with the keyboard has been an intractable problem, and some professional typists have caused hand diseases due to long-term typing. Although there are methods such as "human body keyboard" to reduce wrist fatigue, there is no way to reduce the number of keyboard keys and the plane arrangement. The way of hand movement is not changed, and the problem is limited.

 Third, the keyboard volume can not be reduced, it is not convenient to carry.

Since many human-machine interactive electronic devices can be reduced in size through technological advancement, However, because the main equipment of letters and symbols is large in size, it has not been miniaturized. Especially since the introduction of laptops, wearable computers, handheld tablets, etc., the keyboard has become the main "bottleneck" of these portable devices. In addition, today's cars, airplanes, and home appliances are increasingly using computers as control devices, and it is obviously impossible to arrange more than 100 character buttons on narrow cars, airplane driving panels, and home appliance control panels.

 In view of the above problems, the present invention proposes a new key-shifting keyboard and an input method for applying a key-shifting keyboard. Summary of the invention

Keyboard volume. Through reasonable key arrangement, the whole invention also takes into account the traditional keyboard input habits, which is conducive to popularization and application. By setting the palm rest, the fatigue problem of the traditional keyboard wrist suspension is solved, thereby improving the typing efficiency; the positioning column can make the hand clear I feel the different positions where the moving plane is located. At the same time, the display device is set to prompt for input characters, which solves the problem of inconvenience caused by the finger being always on the button and covering the button.

 Further, the sliding rail is a m-shaped sliding rail, and the moving plane realizes upper, lower, left, right, left oblique upper, left oblique lower, right oblique upper and right under the constraint of the rice-shaped sliding rail The movement of the eight directions is oblique.

 Further, when the keyboard is provided with two moving planes symmetrically arranged on the left and right sides of the keyboard substrate, and the two moving planes are fixedly mounted with five buttons distributed in a five-finger shape, and each When the arrangement of the buttons is adapted to the arrangement of the QWERTY keyboard, the keyboard substrate is further provided with an enter key and a case switch button.

 The principles and features of the present invention are described in the following description in conjunction with the accompanying drawings.

 Embodiment 1

As shown in FIG. 1 , a key shifting keyboard is provided in the first embodiment, including a keyboard substrate 1 , at least one moving plane and a plurality of buttons; the moving plane is mounted on the keyboard substrate through the sliding rails, and is in the sliding rail Restricting the movement of different orientations; the plurality of keys are fixedly mounted on the moving plane for moving the corresponding button to different positions through the moving plane, and pressing the button Corresponding output different characters. The slide rail of the first embodiment adopts a linear slide rail, and the moving plane realizes the movement of the upper, middle and lower directions under the constraint of the linear slide rail. The input characters corresponding to the plurality of keys are changed according to the moving plane to different positions, and the specific changes are as follows: the moving plane can slide on the linear slide to a preset position, and when sliding to each preset position, The sliding varistor 2 (or multi-contact switch) driven by the moving plane sends a corresponding signal to the keyboard chip, and the signal triggered by the single button is also sent to the keyboard chip, and the keyboard chip combines two signals according to a preset program. The character to be entered.

 As shown in FIG. 1 and FIG. 2, in the hardware design, the embodiment is provided with two moving planes symmetrically arranged on the left and right sides of the keyboard substrate 1, which are a left-hand moving plane 3-1 and a right-hand moving plane 3, respectively. -2, the corresponding linear slide rail is also divided into a left linear slide rail 4-1 and a right linear slide rail 4-2, and two positioning planes are respectively mounted with positioning pillars capable of positioning and sliding on the linear slide rails, The positioning post is used to cause the moving plane to achieve different orientation movements under the constraints of the corresponding sliding rail. The two moving planes are fixedly mounted with five buttons distributed in a five-finger shape. The five buttons LK1 to LK5 of the left-hand moving plane are collectively referred to as a left-hand composite button, and the five buttons RK1 to RK5 of the right-hand moving plane are combined. It is called a right-hand composite button, and the arrangement of each button is adapted to the arrangement of the QWERTY keyboard. The position of the corresponding button and the shape of the palm are respectively provided with a left palm rest 5-1 and a right palm rest 5-2.

 In this embodiment, each button moves with the movement of the moving plane, and there are three different positions, so that each button can be arranged to arrange three different characters, even if the three characters share a single button, the QWERTY keyboard is used. The 3 rows of character buttons become 1 row, reducing the number of buttons. At the same time, a elastic returning device is arranged between the linear sliding rail and the moving plane, so that the user can sense the sliding direction of the moving plane, and it is easy to know the position where the moving plane is now, and also facilitate the user to leave the moving plane after the palm of the hand again. You can find the position when using this key-shifting keyboard. Here, the elastic returning device can be a returning spring 6 , that is, the middle spring 6 is mounted on the four corners of the left and right moving planes, and the back spring is connected to the keyboard substrate 1 so that the left hand moving plane and the right hand moving plane can be returned in time.

 When inputting characters, the left and right palms are respectively attached to the left palm rest 5-1 and the right palm rest 5-2, and the moving plane is moved up and down by the palm rest. Due to the pulling force of the returning spring 6, the left and right hands can clearly feel " The upper, middle and lower "three different positions, and the finger can basically be fixed on the button on each moving plane, the wrist has to rely on and not dangling.

In addition, since one button is a combination of three characters, it is obviously unrealistic to print three characters on each button, and the finger is basically fixed on the button, and the character mark represented on the button cannot be seen, so the current position needs to be displayed. The letter or symbol represented by the character button. The keyboard substrate of this embodiment is further provided with a display device corresponding to the position of the moving plane, which is a left-hand display device 7-1 and a right hand respectively. The display device 7-2 is configured to prompt the user to distinguish different positions to which the moving plane slides. The display device can mechanically or electronically prompt the user to move the position where the plane is now swiped, or send the position information to the display for display.

 As shown in Figure 2, the left-hand composite button and the right-hand composite button contain a total of 10 buttons, which can be combined with the "up", "middle" and "down" positions of the moving plane, and can have 10*3 = 30 different combinations. Therefore, it can be used as the main button for keyboard input, and is used for inputting 26 upper and lower English letters as well as Arabic numerals and various symbols. In order to input all the letters, numbers and symbols with these 10 buttons, the face-shift keyboard also has a case, number, symbol switch button, and the composite button position arrangement is arranged. When the Caps Lock, Num Lock, Symbol Lock toggle buttons are off, the composite button is used for 26 lowercase English letters. In the key arrangement, since the arrangement of the "QWERTY" keyboard keys has been formed, the first embodiment does not intend to change the original keyboard key arrangement, and the lowercase English alphabet key table formed by the position of the keys and the moving plane can be arranged as Table 1 shows:

 Table 1

 KL2 | KL3 I L4 I L5 JRI KR2 R3 R4 KR5 " cti Lock isif

 Keys Keys Keys Keys Keys Keys Keys

"Up* position W |~r y [ u i P

"Central ⁵⁵ position S df 1 — shjk 1

― «τ^位置 Z 1 X 1 c Spaee b n H

 '

 Since the above basic English alphabet key arrangement is consistent with the current "QWERTY" keyboard, and conforms to the current popular keyboard typing technique, it is only the original hand hanging up and down to change to the palm of the hand, so it is easy to promote. In addition, since the TAB (tab) and Space (spacebar) are common editing keys, they are arranged in the alphabetic key table. Space (spacebar) is used more, so two buttons are arranged, corresponding to the thumbs of the left and right hands. The English hyphen "-" is also often used in English input, so it is also programmed into the basic English alphabet keys.

 When Caps Lock is closed, the composite button is used for 26 uppercase English letters. The uppercase English alphabet key arrangement is still as shown in Table 1.

When the N draw Lock is closed, the composite button is used for the input of 10 Arabic numerals and some commonly used symbols. Because the number of symbols exceeds 30, and there are only 10 Arabic numerals, some symbols are placed in the Num Lock ON state input. The number and partial symbol key positions are arranged as shown in Table 2: Table 2

 In the key arrangement of Table 2 above, since some of the symbols and numeric keys on the current keyboard are shared by "Shif" (upper key), it is also customary. In addition, the numbers are closely related to the decimal point, comma, plus and minus, greater than, less than, equal to the number of inputs, so these symbols are also placed in the digital input state.

 When Symbol Lock is closed, the composite button is used for the input of other symbols. The key arrangement is shown in Table 3: Table 3

 The above three tables completely arrange all the letters, numbers and symbols on the existing keyboard, and can be input by the left and right hand composite buttons. In addition, other control keys (such as arrow keys, enter keys, delete keys, cancel keys, etc.) are arranged on the keyboard and keyboard substrate. See Figure 2 for details. The keyboard of the first embodiment has a total of 32 buttons, which can fully realize all the functions of the currently popular computer 101 keyboard, which can greatly reduce the keyboard area.

FIG. 3 is a circuit schematic diagram of the left-hand composite button of the keyboard, and the principle of the right-hand composite button circuit is the same. From the circuit diagram, it can be seen that when any left-hand composite button is pressed, because the left-hand moving plane position is different, the sliding varistor is driven to generate different resistances (or drive the multi-contact switch), and the corresponding signal is sent to the keyboard chip, a single button The signal triggered after being pressed is sent to the keyboard chip, and the keyboard chip combines two signals according to a preset program to determine the character to be input. Similarly, when the three switch buttons of Caps Lock, Num Lock, and Symbol Lock are opened or closed, the other 'J resistors are connected in parallel with the composite button resistors, so different resistance values are generated for the keyboard circuit identification area. Points produce different characters. Embodiment 2

 As shown in FIG. 4, the second embodiment provides a key-shifting keyboard, comprising a keyboard substrate 1, at least one moving plane and a plurality of buttons; the moving plane is mounted on the keyboard substrate through the meter-shaped rail, and The movement of the upper, lower, left, right, left oblique, left oblique, right oblique, and right oblique directions is realized under the constraint of the m-shaped sliding rail; the plurality of keys are fixedly mounted on the moving plane , used to move the corresponding button to different positions through the moving plane, and press the button to output different characters.

 As shown in FIG. 4, the embodiment is provided with two moving planes symmetrically arranged on the left and right sides of the keyboard substrate, respectively being a left-hand moving plane 3-1 and a right-hand moving plane 3-2, corresponding to the meter-shaped sliding. The rail is also divided into a left-mi-shaped slide rail 8-1 and a right-mi-shaped slide rail 8-2, and the left positioning post 9-1 capable of positioning and sliding on the m-shaped slide rail is respectively mounted on the two moving planes. And a right positioning post 9-2, the two positioning posts are used to make the moving plane achieve upper, lower, left, right, left oblique, left oblique, right oblique under the constraint of the corresponding m-shaped sliding rail And the movement of the eight directions in the right oblique direction. The two moving planes are fixedly mounted with five buttons distributed in a five-finger shape. The five buttons LK1 to LK5 of the left-hand moving plane are collectively referred to as a left-hand composite button, and the five buttons RK1 to RK5 of the right-hand moving plane are combined. It is called a right-hand composite button, and the position of the corresponding button and the shape of the palm are respectively provided with a left palm rest 5-1 and a right palm rest 5-2.

 The structure of the left-hand moving plane and the right-hand moving plane are exactly the same as the working principle. The following is a detailed description of the left-hand moving plane as an example.

 The moving plane is an octagonal shape, and the octagonal sides respectively represent eight positions of upper, lower, left, right, left oblique upper, left oblique lower, right oblique upper, and right oblique lower according to their positions, and the keyboard An octagonal groove for mounting the moving plane is disposed on the substrate, and a position recognition switch with a return spring is mounted on each of the eight sides of the octagonal groove, as shown in FIG. 4, LSI to LS8 The travel switch is identified for the eight left-hand positions of the left shift plane, and RS1 to RS8 are the eight right-hand position recognition travel switches of the right shift plane. In order to display the input characters corresponding to the respective buttons when the moving plane is in different orientations, the keyboard substrate is further provided with a left-hand display device 7-1 and a right-hand display device 7-2, which are connected to the corresponding position recognition travel switch, Enter characters at the prompt button.

Since the position recognition travel switch has its own return spring, it can play the role of the return spring. The 8 position recognition travel switch is applied with no external force, so that the left hand movement plane is in the "medium" position. , you can enter 5 different characters separately. When the left hand is pressed on the left palm rest When pushing the left hand movement plane to move in any of eight directions of "up, down, left, right, left oblique, left oblique downward, right oblique upward, right oblique downward", the left hand position recognition stroke switch in the corresponding direction has One must be connected. At this time, after pressing the left-hand composite button, the voltage input to the keyboard chip, due to the position recognition of the stroke switch, the circuit changes, the voltage also changes, the keyboard circuit can output another difference. "The other 5 different characters in the position. In addition, there are two commonly used fixed keys on the keyboard base, namely the case switch button 10 (CapsLK button) and the enter button 11 (Enter button).

 In this embodiment, the keyboard substrate is further provided with a keyboard/mouse switching button 12 for switching between the keyboard operation mode and the mouse operation mode. The working principle in the mouse operation mode is as follows: Eight pairs of mouse positioning photocells 13 are mounted on any of the above-mentioned m-shaped slide rails for respectively identifying the upper, lower, left, right, and left oblique directions in the mouse operation mode. , the left slanting down, the right slanting up, and the right slanting down the direction of the mouse movement; in the left hand composite button or the right hand composite button, the two buttons are respectively selected as the left mouse button and the right mouse button, used to move the button through the moving plane to Different positions, and pressing the corresponding button, correspondingly display the mouse movement track in different directions; when the moving plane drives the corresponding positioning column to move to different orientations, the mouse positioning photocell in a certain direction is blocked, and the keyboard chip is pressed after pressing the button This position can be identified, giving the motion positioning of the mouse. In addition, you can also select three buttons, which are used as the left, center and right buttons of the mouse to realize the keyboard/mouse combination.

Figure 5 is a schematic diagram of the key-shifting keyboard. The left-hand composite button and the right-hand composite button are connected in series with their identification resistors (Rl, R2 ······ R10), and then connected in parallel to form 10 different resistance values for identification. Which of the composite buttons is pressed. The left-hand position recognition travel switch and the right-hand position recognition travel switch are also connected in series with the identification resistors (Rl l, R12, ... R28) and then connected in parallel, and 18 different resistance value determination trip switches are also triggered. The button group and the stroke switch group are connected in series, so that 10*9=90 circuit circuits with different resistance values can be formed into a resistance matrix. Here, when the moving plane slides to the preset position, the sliding varistor or the multi-contact switch connected thereto is driven, and the corresponding information is sent to the keyboard chip, and the signal triggered by the single button is also sent to the keyboard chip, the keyboard The chip pair determines the two sets of signals received according to a preset program, and can output different 90 characters correspondingly. The left-hand display device also displays different input characters represented by the five left-hand composite buttons at the current position because the position recognition travel switch at different positions is turned on, which is convenient for input. When the mouse/keyboard switch button (Mouse/Key button) is pressed, the entire circuit is changed by the identification resistors R29, R30, etc., so that the entire circuit loop changes greatly, so the keyboard chip recognizes the input signal as Mouse mode. The mouse positioning photocell is blocked by the up, down, left and right orientations, and different identification resistors are respectively connected in series. The keyboard chip recognizes the orientation through a specific Rom/Ram program, and inputs a computer and other devices for the mouse. Target positioning. At this time, press the RK2, RK3, and RK4 keys on the right hand movement plane. In the mouse mode, the keyboard chip processes the left, middle, and right buttons of the mouse and inputs them to a computer or the like.

 In this embodiment, the buttons arranged in the original plane are moved, and the buttons are pushed up and down and left and right by the palm or the fingers. Each button has "up, down, down, left, right, left oblique, right oblique, left oblique, Right obliquely below" Nine relative movement positions, you can arrange 9 different characters on one button, so that 9 characters can be combined and used one button. For example, when a button is in the "medium" position, the character "B" can be entered after pressing; when pushed to the "up" position, the character "A" can be entered after pressing; when pushed to "below" " When you press the position, you can enter the character "C" after pressing it. In this way, the current row of buttons on the QWERTY keyboard can be turned into a row. In theory, most people have 10 fingers, so arrange 10 buttons that can move up, down, and down, which can form 10* 3=30 different positions, arrange 30 characters input, so that 26 English can be realized. The characters are entered. It can be distinguished by different positions such as left, right, oblique, and oblique. These 10 buttons can be used to input all common characters. In order to determine the position of the button when inputting, it is necessary to arrange a return spring on the moving plane, so that when the hand moves the moving plane, the button can be clearly perceived in different positions of "up, down, down" for convenient input. For the mouse operation mode, since the moving plane has 8 orientations of motion, it is the same as the keyboard operation mode, and the left and right mouse movements of the mouse can be realized by the buttons.

 With the key-shifting keyboard designed in this embodiment, the input method of the transmission is compressed. As shown in FIG. 6, the input method of the key-shifting keyboard is used in the embodiment, which includes the following steps: pushing the moving plane to make the moving plane Under the constraint of the m-shaped slide rail, the movement of the upper, lower, left, right, left oblique, left oblique, right oblique and right oblique directions is realized; when the corresponding button moves to different positions with the moving plane, Press this button to output different characters.

 In the input method, when a mouse input is required, the keyboard/mouse switching key is pressed, and then the left mouse button and the right mouse button in the moving plane are pressed, and the mouse motion track corresponding to the different directions is displayed corresponding to the position of the moving plane. . Similarly, when the case switch button (CapsLK button) and the enter button (Enter button) are pressed, different characters are output.

When the character is input by using the key-shifting keyboard described in the second embodiment, the finger is always on the button, and a palm rest is used to push the button to move, so that when the keyboard is input, the finger is not moved to find the button. Greatly improve character input efficiency and reduce hand fatigue. Because the finger is always on the button when inputting, it is easy to get used to it, and it can achieve "blind" without professional training. In addition, since the finger is always on the button and the button is covered, a display device is also provided for prompting the input of characters, one way is displayed on the computer screen by software, and the other is One way is through hardware display (such as liquid crystal display strip) on other parts of the keyboard surface.

 In order to input all the characters of the existing 1 01, 10 04 keyboard with very few keys, it is necessary to arrange the keys reasonably. As shown in Figure 1, the key shift keyboard arranges LK1, LK2, LK 3, LK4, LK5, RK RK2, RK 3, RK4, RK5 for a total of 10 mobile buttons (the right and left hands of the corresponding person) and two fixed buttons. CapsLK (case switching button), Ent er (Enter). The typing keys of the present invention are arranged as follows:

 First, the basic English alphabet typing key arrangement

 In the key arrangement, since the arrangement of the "QWERTY" keyboard keys has been formed, the present invention does not intend to change the original keyboard key arrangement. The basic idea is to arrange the basic English alphabet typing keys in "upper, middle, Under the "three main moving directions, the lowercase English alphabet key table formed by the position of the button and the moving plane can be arranged as shown in Table 4:

 Table 4

Since the above basic English alphabet key arrangement is consistent with the current "QWERTY" keyboard, it conforms to the current popular keyboard typing technique, and it is only the original hand hanging up and down to change to the palm to move under the palm, so it is easy to promote. In addition, since ",", "·", English hyphen "_", Space (space bar) are often used when inputting letters, they are commonly used alphabet keys, so they are arranged in the basic alphabet of English letters. 7 is the schematic diagram of the key-shifting keyboard of the embodiment. When the 5-character button "ASDFG" is moved upward, the position of the "QWERT" can be input as the position changes. When it is in the "medium" position, you can enter the five characters of "ASDFG"; when it moves down, you can enter another five characters of "ZXCVB". When the case switch button (CapsLk button) is closed, the composite button is used for 26 uppercase English letters. The uppercase English alphabet key arrangement is shown in Table 5.

 Second, the number and symbol, the control character typing key arrangement

The input of numbers, symbols, and computer control characters is arranged in "left, right, oblique, and oblique" positions, as shown in Table 6:

Table 6

The above key arrangement completely completes all the letters, numbers and symbols on the existing keyboard, and can be input by 10 composite buttons. In addition to this, the Enter key (Ent er) is a commonly used button, which is arranged in other positions on the keyboard. The key-shifting keyboard has a total of 12 buttons, which fully realizes all the functions of the popular computer 01 keyboard, greatly reducing the keyboard area. The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., which are within the spirit and scope of the present invention, should be included in the protection of the present invention. Within the scope.
