Description

Universal mouse and keyboard

Technical field

The invention relates to computer peripheral equipment, in particular to a computer mouse and keyboard technology. Background technique

At present, the known mouse and keyboard are mostly independent in layout. Although the mouse and keyboard are made together on laptops and some new products, the mouse and keyboard still have obvious partitions in the layout. In the interchangeable use of these devices, the arm still needs to be moved and repositioned to a large extent. At the same time, too many keyboard keys and keys have relatively insufficient symbols and functions, especially in the formation of combination keys. One key must be Ctrl, Alt, Shift, not one of the necessary keys. These problems restrict us from using keyboard input to express more meaning to the computer, and also restrict the wider use of the keyboard on handheld computers and other devices. . Summary of the Invention

The purpose of the present invention is to provide a universal mouse keyboard in order to overcome the trouble of large-scale movement and repositioning of the arm during the interchangeable use of the existing mouse and keyboard.

Another object of the present invention is to provide a universal mouse and keyboard, which can not only supplement the lack of characters or functions that can be expressed by a computer with existing keyboard input, but also eliminate the problem that the mouse and keyboard cannot be conveniently used in a handheld computer. Or the function is realized by the operation of the keys, which becomes simpler.

In order to achieve the above object, the technical solution of the present invention is to provide a universal mouse and keyboard, which is composed of a keyboard or a keyboard and a mouse, and is an input device implemented by a keyboard or a keyboard and a mouse input scheme, layout, coding logic, and circuits. There are multiple keyboard keys of this type, and the input scheme of this keyboard key is: any one of the keyboard keys is pressed and released once, which can generate the characters or functions of the corresponding key operation, but cancel the repetition of the key Key processing; Press and hold any keyboard key alone, and then press the other key to generate new characters or functions for the corresponding key operation. If necessary, you can also give the ordered key combination the function of enabling repeated key processing. .

In the general-purpose mouse and keyboard, the input scheme provides a help screen that can be output on the display and corresponds to pressing and releasing the keys; the most commonly used characters are the correspondence between the key operations and the realization of characters or functions The symbols or functions are optimized for keyboard keys based on the principles of convenient memory and finger operation.

In the universal mouse keyboard, the keyboard keys are arranged on the disk body in one part or in two parts, and each part of the keyboard keys is divided into 3 to 4 rows and 3 to 5 columns.

In the general-purpose mouse keyboard, the mouse button is placed on the side of the keyboard key, and the cursor displacement sensing element of the mouse is placed on the side of the keyboard key or the disk body; the keyboard key, the cursor displacement sensing element of the mouse, and the mouse key In the relative position of the keyboard, when the fingers are naturally extended, the hand-shaped cavity formed by the proximal, middle, and palm of the hand, the cursor displacement sensing element of the mouse and the mouse key are placed on the finger's finger. At the end, the mouse's cursor displacement sensing element can also be placed on the disk.

In the universal mouse keyboard, the keyboard keys are composed of one part or two parts, and each part of the keyboard keys is divided into 3 to 4 rows and 3 to 5 columns, and the mouse key is composed of keyboard keys or a combination of keyboard keys without repeated key functions. Instead of the keys, the cursor displacement sensing element of the mouse is placed on the disk body, and the friction between the finger and the keyboard causes the finger to move the disk body, thereby realizing the movement of the cursor.

When the universal mouse keyboard is divided into two parts, it is two independent parts, one of which is a disk body and the other is a mouse; keyboard keys are arranged on the upper part of the mouse.

In the general-purpose mouse and keyboard, the space bar can be removed in the layout, and its function can be replaced by other one key in the keyboard.

The technical solution adopted by the present invention is specifically −

1. Input scheme: In the key press operation, scan code formation, scan code conversion, and character or function implementation, multiple keyboard keys of this type are used. The input scheme for this keyboard key is any keyboard The operation of pressing and releasing a single key once can generate characters or functions for the corresponding key operation, but cancel the repeated key processing of the key; press and hold any keyboard key alone, and then press the other key. Can generate new characters or functions for corresponding key operations, and can also give the ordered combination keys the function of enabling repeated key processing when necessary; when three or more keys are pressed, a specific scan code is released for all keys, and Lock the keyboard to invalidate subsequent operations, and it will not become effective until all keys are released; Key operation scan codes are all regarded as the combination key scan codes of orderly double keys that can recognize the press action and key codes. For single keys The push-and-release operation can supplement specific scan codes to form an ordered double-key combination key scan code. After the keyboard interface receives the combination key scan code, the scan code is converted by the keyboard interface disk microprocessor, and corresponds to a two-dimensional table that can be called by the keyboard BIOS interrupt service routine. Or function. Implement these key operations, coding formation, logical judgment, calling and searching of two-dimensional tables, characters or functions To achieve this, it is necessary to modify the keyboard microprocessor's judgment program, scan code formation, keyboard interface disk microprocessor's scan code conversion, keyboard BIOS interrupt service program, and add driver software if necessary.

2. In the layout, the present invention divides the keyboard, the keyboard keys of the mouse, the mouse keys, and the cursor displacement sensing element of the mouse into two parts corresponding to left and right hands on the disk body for layout. The keyboard in each part of the disk body The keys are divided into 3 ~ 4 rows and 3 ~ 5 columns; the mouse keys are placed on the side of the keyboard keys, and they can be arranged only on one part of the disk body, or they can be arranged on both parts; the cursor displacement sensing element of the mouse is arranged on A part of the disk body can be placed on the side of the keyboard key or the disk body, such as the touch pad, track point, and track ball can be placed on the side of the keyboard key. Or optical-mechanical components can be placed on the disk body; in the relative positions of keyboard keys, mouse keys, and cursor displacement sensing elements of the mouse, when the keyboard keys are placed naturally out of the fingers, In the middle, the palm rests), the cavity in the shape of the hand formed by the middle finger and the palm (the keyboard keys in the cavity will not cause misoperation due to the operation of the mouse), the cursor displacement sensing element of the mouse, and the mouse keys Finger At the distal phalanx (finger), the mouse cursor displacement sensing element may be positioned tray, moving operation with the corresponding finger or hand.

3. In the implementation and help of characters or functions, using a keyboard with a composition of 26 or more such schemes as an example, due to the operation of any ordered double key, a corresponding combination of key operations can be formed. Scan codes, characters or functions, so that key operations can form at least 26 X 26 = 676 specific characters or functions. In order to facilitate memory, in the combination key operation, the key is first used as a class function key to specify a certain type of function, and the second key is used to identify one of these functions to achieve the corresponding character or function of the operation, thereby dividing the combination key. There are at least 26 different characters or functions. Among them, a certain key is designated as an input method function key. Press this key first, and then press the other key combination to operate. At least 25 different input methods can be called. An input method corresponds to a two-dimensional table that can be called by the keyboard BIOS interrupt service routine. In different input methods, different characters or functions can be implemented through different definitions of each element in the two-dimensional table, thereby achieving at least 26 X 25 X 25 = 16250 specific characters or functions; Under a certain input method, a single key press operation can be used to input 26 English characters, or through Wubi fonts such as Chinese character input, pinyin and other software coding Way to realize the input of a certain language, and the ordered double key combination can realize the input of new characters or functions. In addition, in order to eliminate memory barriers in the use of such huge characters or functions, and easily implement an orderly double-key combination key operation to input corresponding characters or functions, the software method is used to provide help that can be output on the display Screen, as opposed to pressing and releasing keys Therefore, when a key is held down, the help screen displays prompts for the functions represented by the key, and the remaining keys display prompts for characters or functions that can be achieved when the key is pressed again. In the correspondence between key operations and the realization of characters or functions, the most commonly used characters or functions are optimized for keyboard keys based on the principles of convenient memory and finger operation.

4. In addition, the multifunctional keyboard can be composed of only the keyboard keys in the general mouse and keyboard layout, or the one-handed mouse keyboard can be constituted by the part of the disk body with the mouse function, and the same technical solution is adopted in the realization of characters or functions.

5. Since the keyboard keys are mainly operated by a single key or an ordered two-key combination, both can input specific symbols or functions, so that the present invention can achieve rich key input with only a small number of keys Function, and the number of keys is reduced, which greatly reduces the volume and weight of the disk body. The friction caused by the light contact between the finger and the keyboard keys can realize the finger movement to the disk body, and the characters or functions that the keys can achieve are This richness makes it possible and necessary for the keyboard and mouse to further merge in many aspects such as operation, function, logic, and processing chip. The method is to use the mouse keys with finger keys that are convenient for operation, and do not include the repeated key functions. Or the keyboard key combination is replaced, and the cursor displacement sensing element of the mouse is placed on the disk body, and the friction of the contact between the finger and the keyboard key causes the finger body to move the disk body to achieve the movement of the cursor; in electronic logic And processing chips, part or all of the keyboard key input scheme and keyboard keys or keyboard key combinations proposed by the present invention are used The key combination replaces the mouse button scheme, and to meet a variety of needs, it can be endowed with certain logic setting capabilities.

The beneficial effects of this universal mouse and keyboard are mainly reflected in its versatility-

1. Small number of keys, easy to type blindly; small size, portable; integration of mouse and keyboard layout functions, which basically eliminates the trouble of large arm movement and repositioning of opponents during mouse and keyboard interchange operations, and the device can Widely used in desktop computers, notebook computers, palmtop computers (such as foldable keyboards), wearable computers (such as using a conductive fabric to make the mouse and keyboard into two parts and placed in two trouser buckets, just need to make their positions simple Adjust it to make it easy for people to lie down, sit, stand, or even walk.)

2. Because the universal mouse and keyboard can enable any single key or any ordered two-key combination operation to achieve the input of specific symbols or functions, for example, 26 or more keyboard keys of this scheme, and use "input One key combination operation of "Method switch key" + one of the other letter keys can facilitate the call of any one of at least 25 input methods. Different input method definitions make the mouse and keyboard convenient for use in multiple countries, Multi-ethnic languages, or certain types of functions such as office, home appliance control, programming, and industrial equipment control, are more convenient to switch and use, and avoid the inconvenience of switching input methods in current computers. Of course, most application software only supports the current keyboard. To realize the rich functions of the universal mouse and keyboard, the application software needs to provide good support.

3. Under a certain input method, as any one-key or any ordered two-key combination operation of the universal mouse and keyboard can realize the input of specific symbols or functions, for example, there are 26 or more of this program. The keyboard keys make it easy to achieve at least 650 symbols or functions. A total of 25 input methods can achieve at least 16250 symbols or functions. This allows us to easily implement extremely rich characters or functions through key input. When new characters or functions need to be entered by using keys, only the two-dimensional table needs to be modified, so that it is possible to break the restrictions of ASCII code and its extension code, and its layout and key combination operation methods are also reflected in a concentrated way. It has the ability to express rich meanings conveniently by human operation, and the good adaptability of human hand to the universal mouse keyboard.

4. The rich functions of the mouse and keyboard make it possible to provide good support and expansion for new characters or functions that need to be implemented by key input in the current and future development of software and hardware. For voice or handwriting input, even if such input is improved, it is impossible to replace key input). BRIEF DESCRIPTION OF THE DRAWINGS

Since the number of keyboard keys of the present invention is relatively small, coded keyboards and non-programmed keyboards are used for implementation. Code keyboards are relatively easy, and there are many schemes in the layout, as shown in Figure 1, Figure 2, Figure 5, Figure 6, Figure 7, and Figure 9. Here, only non-coded keyboards are used as an example. It is similar to traditional computer keyboards. The difference between the mouse and the mouse lies in the key surface layout, the number of keys, the operation method, the scan code formation, and the keyboard BIOS interrupt service routine call. The scanning circuit and the debounce circuit can be the same. The unique features of the invention will be used to explain it. In terms of correspondence between operations and the realization of characters or functions, the realization functions of the combination keys can be defined according to the principle of convenient memory, operation and realization of characters or functions.

Figure 2 is a schematic diagram of the layout of the generic mouse keyboard of the present invention by adding function-like identifiers to keyboard keys. It is composed of mouse keys 1, trackball 2, and 28 keyboard keys (26 English alphabet keys, space bar, and input method keys). A layout scheme consisting of two parts can be an integral part or two parts. The lower line of each key represents an example of the type of function implemented by the key. In addition, in the same industry, the same symbol on two adjacent keys indicates the combination. The characters or functions implemented by the keys, such as the combination of the right index finger and middle finger, simultaneously pressing "H, J" or "J, H" to achieve "Enter" in the ASCII code, and other adjacent key operations By analogy, this key combination operation is almost as simple as a single key operation. It is used to implement the most common characters or functions other than the 26 English alphabet keys, space bar, and input method keys, such as Enter, Esc, Del, Backspace, The meaning of other keys in such functions, such as commas and periods, is exemplified in the table in FIG. 4.

A, B, and C represent any keyboard keys different from each other. "1" represents a key operation, and "0" represents a key operation, such as "A1.""Means pressing the A key," AO "means letting go of the A key,"-S "means that the double key function is implemented after a certain period of time when the double key is pressed; the second column shows the formation of an ordered double combination key scan code," 00 " Represents the specific scan code supplemented when a single key is pressed, where the specific scan code supplemented when a single key is pressed is in the back, and the specific scan code supplemented when a single key is put is first, "00A0" indicates the key release operation of the single key A or press The specific scan code output when the next three keys are pressed; the third column indicates the scan code conversion, where key replacement operations are replaced by *, "00" are replaced by "0", such as "00A0" is replaced by "0 *"; fourth The column represents the character or function implemented by the corresponding operation, where no character is indicated when empty Or the function is realized; The fifth column indicates the change caused by the corresponding operation to output the help screen on the display. FIG. 4 is another logical table diagram of the universal mouse and keyboard of the present invention. It is a two-dimensional table called by the keyboard BIOS interrupt service routine. The first row and the first column are the header, and the first column is the ordered double combination. The first key of the key is the second key of the ordered double combination key, corresponding to the third column of FIG. 3, and the character or function realized by the corresponding operation is obtained by checking the table; there is one character or function in the table The slash zone is the most commonly used character or function except the 26 English alphabet keys, space bar, and input method keys. No matter which key combination is pressed first, the key combination produces the same effect, which is achieved by the combination of two adjacent keys. For example, "1, U" or "U, I" means "Del" in ASCII code. The shaded part in this table is the invalid area, and the vacant part is the undefined part.

Correction page (Article 91) 1. In layout: For example, a layout of 28 keyboard keys is shown in Figure 1. The keyboard keys are arranged in two parts on the panel. The first part of the keyboard keys is divided into 4 rows and 5 columns with a total of 16 keys, and the other part of the keyboard keys. There are 12 keys in 3 rows and 4 columns, including 26 English character keys, space bar, and input method switching keys. In the relative positions of the keyboard keys, the mouse's cursor displacement sensing element, and the mouse keys, the keyboard keys are placed naturally on the fingers. When opening, the hand-shaped cavity formed by the proximal knuckle of the hand (of the three knuckles of the finger and the one by the palm), the middle knuckle and the palm, and the trackball and mouse button are placed at the remote knuckle of the finger ( (Finger end), use the corresponding finger to operate.

2. In the implementation of characters or functions: First, for the single key press and release operation, press and release the English character key or space key alone to implement lowercase English characters or space input, or Wubi fonts such as Chinese characters. , Pinyin and other software coding methods to achieve the input of a certain language, and when the input method keys are pressed individually, the input method represented by each key is displayed on the keyboard help screen of the display, and the input methods currently in use are distinguished by different colors ; The characters or function meanings of the function keys corresponding to the operation are displayed on the keyboard help screen of the display, and there can be various settings, such as the time to be displayed on the display, never displayed on the display, and only delayed when the key is pressed Display, etc., and the delay time can also be set, and its screen change corresponds to the key operation. Secondly, for the operation of an ordered combination of two keys, the lower line of each key on the keyboard key represents an example of the type of function implemented by the key. As shown in FIG. 2, it means that a certain type of function key is pressed first, and then Press the other one key to realize the character or function of the corresponding key of the corresponding type of function, but the key combination of adjacent two keys is not strictly distinguished by the class function, especially for the key combination of adjacent two keys in the same row. The key operation is almost as simple as a single key operation, so it is used to implement the most common characters or functions except 26 English alphabet keys, space bar, and input method keys, such as Enter, Esc. Del, Backspace, comma, period, etc., Figure 2 The upward arrow symbols on the W and E keys indicate that pressing the combination key WE or EW to move the cursor up. No matter which key is pressed first, the two characters are the same in terms of characters or functions. Other adjacent combination keys And so on. Figure 4 is a two-dimensional table of characters or functions implemented by key operation under an input method. One input method corresponds to a two-dimensional table. Press the input method key first, and then press the other key to implement different input methods and two. Call of dimension table.

3. On the logic of pressing and releasing the key, forming the scan code, converting the scan code, and implementing the characters or functions, make the following logical modifications to the keyboard microprocessor program: Press and release any one of the keyboard keys once Operation to generate a scan code for the corresponding key operation, but cancel the repeated key processing of the key generated after pressing for a certain period of time; press and hold any keyboard key alone, and then press the other key operation to generate a new corresponding key The scan code of the operation, if necessary, can also give the ordered combination key to enable when pressed for a certain time Function of repeating key processing; When three or more keys are pressed, a specific scan code is issued for all keys to release, as shown in Figure 3, and the keyboard is locked to disable subsequent operations until the keys are fully released before becoming Effective; In addition, the formation of the key operation scan code is regarded as a combination key scan code that can recognize the press and release action and an ordered double bond of the key code, and the press and release operation of a single key can supplement a specific scan code to form an ordered double key. The key combination scan code of the key, as shown in FIG. 3, press the A key alone to form an ordered double key combination code of A100, and a single key to release the A key to form an order double key combination code of 00A0. The scan code of the push and release operation of the keys is formed by analogy. The scan code conversion is realized through the program modification of the keyboard interface disk microprocessor (of course, this logic can also be implemented in the keyboard microprocessor), where the key-up operations are converted to the same specific scan code, as shown in Figure 3 As shown in the third column, all are converted to 0 *. The converted scan code corresponds to a two-dimensional table that can be called by the keyboard BIOS interrupt service routine. The first column of the two-dimensional table corresponds to the first code of an ordered two-key combination key scan code, and the first row corresponds to the The second code of the sequential double-key combination key scan code is obtained by looking up the table, as shown in Figure 4, setting the element cell at the corresponding position in the table to 1, and outputting the character or function corresponding to the element cell. The elements are all 0. When the two-dimensional table is in a state that can receive the scan code, when there is a state of 1 in the 0 column (that is, the previous scan code is a scan code that reflects a single key press), the scan code is first accepted. Determine whether the code is 0 *, if not, the two-dimensional table is reset (all elements in the table are set to 0), and then accept the scan code and check the table; if so, the two-dimensional table is not reset, directly accept the scan code and check the table, and Only when there is an element grid of 1 in the * column, the element grid of 1 in the 0 column can output characters or functions. The addition of this judgment is to realize that the 27 single keys other than the input method switch key are pressed first and then placed. Single-key input, when all 0 columns are 0, the Dimensional code tables when scanned, two-dimensional table are first reset in order to cancel out the influence of the scan code of a look-up table, the logic shown in Figure 8, which also requires BIOS keyboard interrupt service routine to make the corresponding modifications to implement this logic. Because an input method corresponds to a two-dimensional table, driver software can be added to implement it if necessary. Figure 4 shows a two-dimensional table under an input method. In addition to IJ, when the computer is started, the English character input method is always used as the default input method to start, so as to facilitate the setting of the CMOS during the startup. In addition, because the English characters implemented by a combination of keys and the English characters implemented by a single key correspond to different positions in the two-dimensional table, it can be specified that only English characters implemented by a single key can implement coding methods such as Wubi fonts, Pinyin The activation of the input method is implemented, so that under an input method such as Wubi font, there is no need to do any switching. Before activating the input method, you can use a combination key to input uppercase or lowercase English characters. The keyboard help screen output on the display is implemented by driver software. The logic corresponds to the two-dimensional table. The screen changes correspond to the key operation changes, as shown in Figure 3 and Figure 4.
