4.2 the setting of keyboard system and function

Keyboard system involved in the present invention is made up of the key board unit with above-mentioned feature and support circuit, program and method of operating.Because the correlation technique resource is very abundant aspect circuit and program, have multiple choices so can reach the solution of system's needs; The present invention simultaneously has extensive applicability, and actual product can be with computing machine of being joined or product specification, use occasion is different makes required technical conditions also different, and these also will mainly be reflected on circuit and the program.Therefore, for related application is technical to have more dirigibility selecting in the specific implementation, this patent will not made regulation to the concrete technical scheme of circuit and program, under the principle that the professional who makes field under the present invention can be implemented, only relate to its necessary feature, the function that is showed and distinctive method of work.Below will be by the function and the method for operating of mentioned above principle to keyboard system, and other structures of relevant therewith key board unit and working condition are described further.

Its basic characteristics of input method involved in the present invention are to utilize keyboard rotate to produce switching signal, make keyboard when a position turns to another position, can import different characters in same key position.Realizing this input method and making it to operate is that a series of settings and function thereof by keyboard system forms.

4.2.1 the setting of character bit matrix

In keyboard system, need to set up a virtual keyboard by program, dummy keyboard is a character bit matrix, this matrix had both shown as the switching plane between the content of operation signal that keyboard sends and input computing machine, also showed as the platform that the user exchanges with keyboard system.Each point in the matrix is set to the character bit of a definable input character, the key position on its corresponding keyboard of each row, the character of representing this key position to import; Corresponding one of its each row " dish position " are represented a kind of transition status.Matrix and practical operation relation are: rotary keyboard is exactly in the changeover panel position, and keyboard places a certain dish position, be exactly should dish in the matrix respective column selected and place current state; Knock the key position this moment, is exactly that this row is selected, and the character that defines on the character bit of row and row intersection point just is transfused to.

The dish position is by keyboard the relative position on chassis to be determined.In practical operation, staff is owing to limit by the wrist joint mobility, and the angle that drives the keyboard rotation in keystroke is limited.Under the motionless situation of arm, the angle that the palm along continuous straight runs rotates is about 60 °, so the rotation of changeover panel position will be carried out in this scope.For the operation of coiling the position conversion is convenient to grasp, each dish position need take certain angle.Each dish position of this example accounts for 8 °, is provided with 7 dish positions, that is to say between these 7 the dish positions and can directly change mutually.In matrix, these 7 the dish positions that can directly change mutually pairing 7 are listed as " keypad " that the submatrix of being formed is known as dummy keyboard in this manual.As can be seen, in practical operation,, promptly in matrix, outside the choosing row, also need regulation conversion keypad except the operation of needs regulation changeover panel position---promptly select the operation of submatrix.

In the present embodiment, dummy keyboard has 3 keypads, and each keypad has 7 dish positions, be that the character bit matrix is divided into 3 submatrixs, each submatrix is 7 row, 20 row (corresponding with 20 key positions of keyboard), so matrix is 20 row, 21 row, have 420 character bits, see Table 2.In actual product, can also increase keypad, escape character position capacity again by setting up submatrix with further expansion keyboard system.Each character bit can define a character, operation for convenience, and same character can define on a plurality of character bits.Defined in table 2 is default character, is the character that QWERTY keyboard can be imported, and all the other spaces are character bit to be defined.

4.2.2 character, dish position, keypad and operating function thereof

Character is the pairing input content in finger tapping key position, character of a keystroke input.In the present invention, its content can be general keyboard symbol, control instruction, also can be by user-defined other guide.

The keyboard revolution changes a dish position, and the current character of key position correspondence is replaced once.4 middle dialer positions are preferential dish position, and keyboard starts at every turn, and keyboard system will be arranged on this dish position automatically, and turning left later on is followed successively by 3 dialer positions, 2 dialer positions, 1 dialer position, is followed successively by 5 dialer positions, 6 dialer positions, 7 dialer positions to the right.Accompanying drawing 4 is dish position synoptic diagram (scale among the figure is an imagination), and figure below is the keyboard relative position, and last figure is the current character of this correspondent button position, dish position, also is the content of screen display.State when this figure represents specifically that this example keyboard system is in the 4 dialer positions of keypad II (a figure) and 6 dialer positions (b figure).

This example is provided with 3 keypads, and I is self-defined district, and II is the letter character district, and III is a function key area.Two kinds of conversion regimes are arranged, the one, set dedicated convert key position or character, the one, with the rotation of transfiniting of dish position: be in keypad II as keyboard system, then rotary keyboard then enters the 1 dialer position of keypad I left above 1 dialer position; Surpass 7 dialer positions to the right, then enter the 7 dialer positions of keypad III.

The dish position switching signal of keyboard system can be provided by the relative movement drives conversion element between keyboard and chassis or keyboard and the roller.Two kinds of motions and the conversion element that is driven thereof are not established the dead point, and be promptly all free to rotate, and the dish position the when starting point of dish position is started by keyboard system is set to middle preferential dish position automatically and determines that keypad then is the keypad that used last time.Rotation amplitude surpasses dish position limit and then is converted to another keypad (see on) adjacent with former keypad, and bigger amplitude is an invalid operation ⁽⁴⁾3 characteristics are arranged on the translation function of dish position:

(1) put automatically: as mentioned above, in this example each key position the keyboard rotational angle that accounts for be 8 °, that is to say that there is 8 ° scope of activities each dish position, surpasses these 8 ° and will be transformed into another key position.In practical operation, keyboard system will place the dish position mid point of this dish position automatically behind each keystroke, and Here it is puts automatically.If the changeover panel position just need be rotated more than 4 ° to the left or to the right, if the dish position of conversion is adjacent with former dish position, then rotation amplitude R is:

4°＜R＜8°；

If the centre is separated with n dish position n=0 when adjacent), then have:

(1+2n)*4°＜R＜(1+n)*8°。

This function can be avoided because of cause unwanted automatic conversion behind the multitap of same dish position.

(2) carry changes the district: this function has been done detailed presentations in " keypad " illustrates.What need here to replenish is: if the carry amplitude then directly is transformed into next keypad greater than 8 °, as the direct conversion between No. 1 keypad and No. 3 keypads; If no keypad is interchangeable then to be invalid operation, turn left or No. 3 keypads turn right as No. 1 keypad.

(3) playback at any time: since have put automatically in function cumulative errors or change the district through carry repeatedly, the physical location of dish position can change, in order to return to suitable position so that operation needs the function that playbacks at any time.Establish a playback point at the locking bit of palmrest for this reason, press the preferential dish position that palmrest dish position automatically reverts to this keypad.

4.2.3 the operating function of palmrest

In this example, 13,15,17 keys respectively have 3 key positions, conversion between these 3 key positions is by placing the change-over circuit between keyboard and the palmrest to realize, method is as indicated above, the position of finger corresponding palmrest when impacting 3 key positions, upper, middle and lower respectively is also different, thereby has realized conversion thereupon.In actual product,, also can respectively be divided into 3 buttons as not establishing mouse function.But because these 9 key positions are high-frequency key positions, hit in the middle of two keys if be divided into out when quick keystroke easily mistake, cause two characters of input on the contrary, use circuit conversion can avoid this situation to take place.

Palmrest also has a keyed end mentioned above except having key position translation function, end is still upspring the playback function at any time of realization dish position for the playback point after the relieving at that point; Go into overdrive to press down from the playback point, mechanical lock mechanism locks it in this position, and keyboard system is closed, and then can be exchanged into Genius mouse as additional mouse function; Press then locking mechanism unhook once more, palmrest is upspring, and keyboard system is opened again.

4.2.4 mouse function

Key board unit adopts the form of present embodiment, can increase mouse function for keyboard system at an easy rate: circuit and program that configuration is correlated with can be made as mouse state with the lock-out state of palmrest, or shift key is set on keyboard is converted to mouse state.In digital (15) and unknown digital (17) be fabricated to slide and touch device, the control Y direction of mark and mouse of rolling respectively, the directions X of keyboard rotation mouse beacon; Forefinger key 13 is made as left mouse button, and other keys are made as right button ⁽⁵⁾

4.2.5 duty indication

Because each key position represents delegation in the character bit matrix, every in the present embodiment row has 21 character bits to be difficult to learn by heart one by one, and if there is not indication, also can't know current selected be which row, so keyboard system must be indicated the current row situation of selecting.Therefore keyboard system is provided with the duty deixis, and two kinds of indicating means are arranged:

(1) pilot lamp indication: keypad pilot lamp (6) is indicated keypad I, II, III from top to bottom successively, and dish position pilot lamp indicates 1 dialer position to 7 dialer positions from back to front successively.Before starting, computer operating system can operate by learning character by heart or contrasting printed matrix table.

(2) keyboard system realizes that by supporting program character screen shows.Enter at computing machine under the condition of operating system, after keyboard system was opened, a window just appearred in screen, program can when the pairing rectangular array in shroud position with the mode of keyboard face synoptic diagram be presented on the corresponding keys position, indicate keypad under it simultaneously.See accompanying drawing 4 last figure.

4.2.6 default character and self-defining character

Explain conveniently for instructions, provide the reference scheme of a default character in the present embodiment, in actual product, should on the basis of specializing in, determine a more reasonable plan.Default character mainly is letter, symbol and the function key that existing QWERTY keyboard can be imported, so that be connected mutually with existing operating habit.For former Shift, Ctrl, the Alt key that is used for switching combining, originally can realize direct input (being defined as direct input character) by the input content after its switching of direct definition or the combination as the former character that performs, but present application program all has the content of using these keys, so still need to be provided with these characters, but,, the mode that it should be pressed originally simultaneously presses so changing order into because this key board unit is not suitable for two key positions and presses simultaneously.

Keyboard system can be opened the character bit Matrix List with the form of window by assigned operation, chooses character bit, carries out the operation of user-defined characters with designation method.But character letter character and combination thereof, peer link, text etc.Also can increase submatrix as required increases keypad.

5, the using value of keyboard system

From characteristics of the present invention, the keyboard system of using the present invention's exploitation makes the keyboard and input method of computing machine that very big change take place, and this change can provide a kind of new thinking for the mode of computer keyboard operation at least.With regard to the embodiment of this instructions, compare with present known keyboard form and input method thereof, aspect practical application, also have bigger superiority.

At first, the present invention is being converted into input signal clearly through the palm action after the standard, and the actuating signal that makes staff is horn of plenty more, this with regard to horn of plenty keyboard input content, simplify finger movement and created adequate condition.Therefore can greatly reduce keyboard by bond number and finger keystroke the time movement range, keyboard volume was reduced greatly, it is convenient accurately also to make finger seek the key position, thereby makes operation more convenient.

The one-handed performance of key board unit and small and exquisite volume, as long as can make its have one be equivalent to the big plane of QWERTY keyboard half of the area and palm can and the position can operate, needn't need special-purpose keyboard platform, also needn't limit operation posture, make keyboard operation more light.

One-handed performance can spare the another hand, and this can increase work efficiency concerning the work of cross-operation will be frequently carried out in keyboard operation and other operations.As the text input, a hand can be used for editing and the processing manuscript; Programming, a hand can write down some main points; Window services, a hand can be used for handling bill, or the like.

Custom feature not only can be provided with special-purpose cuit according to the use occasion of computing machine one of makes the key input (as the special-purpose project of window services such as bank, postal service, common expressions in the program), also can be new Chinese character entering technique free platform is provided, needn't be confined to again only to use 26 English alphabet keys positions, also can be recreation new maneuverability pattern is provided.After increasing mouse function, the keyboard that can conveniently realize-mouse conversion can increase new input and control method for the more applications field.

⁽¹⁾For explaining conveniently, " computer keyboard device " shown in this instructions or abbreviation " key board unit " are meant that whole hardware of this device and circuit constitute, and " keyboard " is the keyboard portion (accompanying drawing piece number 1) that specially refers to wherein; Shown in " computer keyboard input system " or be called for short the system that " keyboard system " is meant that softwares such as key board unit involved in the present invention and supporting program, method of work are formed.

⁽²⁾For mechanical type english typewriter (abbreviation typewriter), be input to prefix from the signal of keyboard and print to that this process is to finish by the transmission of power of mechanical hook-up on the paper, so its design form and function just have been subjected to the restriction of mechanical hook-up inherent characteristics inevitably.As: finger keystroke needs certain strength and amplitude, so each button just need occupy certain space, in case interfere mutually; In order to simplify the internal structure of an organization as far as possible and to be easy to make and to guarantee that the reliability of work, each conventional characters all need corresponding button, so just need the button of arranging some, and then the keyboard of the corresponding size of needs; If button is too many, surpass the both hands coverage, can make and look for the key difficulty, the keyboard capacity is restricted.Mechanical hook-up also responds slowly, realizes key multiword symbol difficulty, can't show input state etc. in addition.The keyboard form of typewriter is the product under the Machine Manufacturing Technology term restriction fully thus, has only moving the transferring to of keystroke to turn to input signal under this form, and other actions of staff fail to be used.

⁽³⁾If right hand keyboard then is the left side, so that observe.

⁽⁴⁾This is similar to the mouse mode: mouse is positioned in the middle of the screen during os starting, and outwards dragging when outwards dragging to screen edge then is invalid operation again.

⁽⁵⁾The function of said here left button right button is the definition by present mouse, and the function of the right and left key of right hand mouse.
