The function of mouse is to carry out the movement of mouse beacon migration pointer (hereinafter to be referred as mouse pointer) on screen by the movement of mouse, and by the mobile position of wishing that arrives of mouse pointer, again by associative operation, thereby realize, computing machine is sent to instruction reach operation object.Due to mouse to carry portability be a loss, the following scheme that adopts this keyboard realize that former cause mouse completes to mouse pointer mobile controls and simulate click, the common practicality that drags etc. operates, its guiding theory is to utilize four of left hand dish joint position keys and periphery function key to form mouse alternative functions very efficiently, and its scheme is as follows:

First, we do following description to the utility function of mouse: one: mouse has left and right and upper and lower locomotive function; Two: middle button of mouse has the function that moves up and down the page and carry out Z axis operation; Three: a mouse click right button has the function that ejects shortcut menu; Four: mouse has selected function, first, by mobile, arrive the starting point in chosen region, press left mouse button, to starting point location, continue to pin left button and move to the terminal for the treatment of favored area, unclamp left mouse button, complete selected operation; Five: mouse has drag function; Six: a mouse click left button has the function that changes cursor position; Seven: mouse has clicks the function with double click operation to being instructed to icon; Eight: middle button of mouse has amplification and diminished image function.

First briefly introduce the replacement scheme to above-mentioned functions here:

1: four, left hand dish joint position keys set respectively have left, make progress, mouse pointer locomotive function downwards and to the right;

Under the nameless and middle finger of left hand,---to be subscript key and subscript key---be set as the alternative key of middle button of mouse to key; There is function and the image scaling function of browsing up and down the page;

Setting shift key has and reduces the move up and down effect of speed of mouse.

2: utilize access key, replace the function of clicking of right mouse button.

Set clicking and double-click and replacing clicking and double-click function of left mouse button of F key, because the double-click performance of keyboard is not as mouse, can introduces other modes and substitute double-click function.

3: choosing is set, and to drag key be that region selection function and drag function substitute key,

Duplicate key, shear key and stickup key are set, the content of being selected by mouse pointer is copied and sheared, and paste by pasting key

4: after mouse pointer stops, clicking F key, cursor can be positioned to the position of the editing area that mouse pointer stops;

Subscript key and subscript key have the function of amplification and diminished image, pin subscript key, have the function of lasting diminished image, pin subscript key, have the function of lasting enlarged image.

In order to improve key mapping efficiency, setting F key is combined with 12 character keys of right hand core keypad and is generated F1～F12 function, and this is also the source of F key key name.Because this keyboard has been cancelled the function key that twenties Qwerty keyboards such as cursor 4 keys, page operation 4 keys and F1～F12 are used, relatively many function key mappings can be provided, some common functions as subscript, subscript, advance, retreat, utility function that desktop, printing, preview and Qwerty keyboard need to combine realization as store, copies, shear, stickup etc. can be directly with the appearance appearance of function key.

The merogenesis input problem of stressing English alphabet at this is the implication of four-node input method, so-called four-node input method, structure and the order with the English alphabet is divided into A, H, O, U tetra-joints by the input of English alphabet, and left hand is controlled four joint position keys, and the right hand is inputted corresponding English alphabet.The example that is input as with H joint, H saves to input h, i, j, k, l, m, seven English alphabets of n, during input, left hand is pressed H joint position key, and now, 7,8,9 three numerical keys represent respectively h, i, tri-lowercases of j, numerical key 0 represents lowercase k, 4,5,6 three numerical keys represent respectively l, m, n, and as word him, when only need press leftward or impact H joint position key, the right hand impacts 7,8,5 three numerical keys.The input of other letter by that analogy.Capitalization is squeezed into by shift key.The input of Chinese can transform according to English alphabet, and phonetic method and the Five-stroke Method are all convertible.

As shown in Figure 2, on A, H, O, tetra-joint position keys of U and corresponding singlehanded joint position key, each button is marking 8 punctuates or special symbol, divide upper and lower two row, be positioned at top and the bottom of joint position key, the input method of descending 4 punctuates and special symbol is to press a joint position key, under 1,2,3 three numeral of dial and four fingers at division sign place, key can be inputted these four punctuates from left to right successively, as input ". " number, when only needing left hand to press or impact A key, the right hand impacts numerical key 2.The input of up 4 punctuates and special symbol is just than descending 4 punctuates and the multiplex shift key of special symbol.Input method shown in this section is for the punctuate on four joint position keys and special symbol.

The using method of F key is: press F key, numeral 1,2,3 ..., 9,0, radix point and the division sign generate respectively Fl～F12 function key, as pressed F and Ctrl two keys simultaneously, then presses numerical key 6, can carry out document window switching.

The use of singlehanded joint position key is distinguished to some extent with the use of joint position key, left hand keypad A, H, O, 4 joint position keys of U are that both hands input is used, only be called joint position key, during use prior to or be later than or " simultaneously " and right hand character keys are used, but joint position key and character keys must formation time be intersected, 4 joint position keys of right hand keypad are singlehanded joint position key, only be called singlehanded joint position key, to distinguish with joint position key, press after the key of singlehanded joint position, corresponding pilot lamp lights, finger leaves joint position key, pilot lamp does not extinguish, now can select corresponding character keys to input corresponding letter or radical, press other joint position keys, front pilot lamp extinguishes, rear indicator light lights, after letter or radical have been inputted, the one hand joint position key of clicking light yellow exits.

Another importance of the present invention is exactly to have developed mouse alternative functions on the basis that change dish joint position leftward, for portability has increased new deal.Describe now mouse replacement scheme in detail, with the linguistic form of function setting and functional description, describe here:

One: the principle of substitution:

Utilizing mouse to control mouse pointer, is that the displacement with respect to backing plate carries out by computing mouse roller or mouse.With button, replacing mouse, is to carry out mouse beacon pointer by changed into the speed that is multiplied by regulation by time quantum by displacement mouse beacon pointer.

Two: mouse locomotive function substitutes:

1: keypress function setting:

Four joint position keys of left hand are set and are respectively left, upper and lower, right mouse migration pointer movement function key:

Two keys operate simultaneously realizes oblique movement;

The function replacement key that subscript key and subscript key are middle button of mouse is set:

Pin subscript key, replace promoting forward middle button of mouse,

Pin subscript key, replace pulling back middle button of mouse;

It is that the page moves up and down function key that subscript key is set:

Press subscript key, the page moves on line by line, presses subscript key, and the page moves down line by line;

Click subscript key, realize Page Up and Page Down function;

Shift key+upper subscript key, realizes Home and End function;

It is web page operation function Macintosh that space bar+upper subscript key is set:

Space bar+upper subscript key is clicked, and webpage enters page or nextpage;

The page that is combined as that space bar and A key and U key are set moves left and right function Macintosh:

Space bar+A key, the page is moved to the left; Space bar+U key, the page moves right;

2: move up and down normal speed and regulate to arrange of mouse:

Time segment length: 150ms, often completely a period mouse moves once

Click and support deduction time limit: 250ms

Standard speed: each period is moved 5mm

Speed at a slow speed: each period 0.5mm

At a slow speed to the mark speed conversion time limit: 1 second

Click mobile each mobile 0.5mm

Deceleration multiplying power: 1/5th

Move for the first time and betide 20ms constantly

The page speed setting that moves up and down:

Time segment length: 150ms, often completely a period page movement is once

Click and support deduction time limit: 250ms

Per period middle button of mouse moves 0.5mm

Page of every click sends Page Up or Page Down signal once

The upper subscript key of Shift+ is clicked and is sent Home or End signal

Space+upper subscript key is clicked and is sent page or lower page signal

Mobile betiding clicked end or the full 400ms moment for the first time

The rapidly state mouse speed setting that moves up and down:

Space bar+F key, can carry out changing between the rapid state of mouse and normal speed state

Time segment length: 50ms, often completely a period mouse moves 1 time

Each mobile 10mm

Deceleration multiplying power: 1/10th

Move for the first time and betide 20ms constantly

Press choosing and drag key, keyboard directly enters normal speed state

3: the state conversion of mouse function and input function:

Default conditions: mouse function state

Mouse function state proceeds to input state:

It is that input state proceeds to key that space bar is set, and under mouse state, clicks space bar, proceeds to input state;

Input state proceeds to mouse function state:

Input operation pauses and reaches a specified time, and regulation reaches 1 minute herein, proceeds to mouse function state;

Choosing is set, and to drag key be that mouse state proceeds to key, under input state, clicks choosing and drag key, proceeds to mouse state;

Three: mouse operating function substitutes:

1: keypress function setting:

F key is set and for clicking with double-click function, substitutes key:

Choosing is set, and to drag key be that region selection function substitutes key:

Treat the starting point of favored area, pressing choosing and drag key, determining start bit,

Mouse pointer is reached home, and presses choosing and drags key, completes region and selects;

Choosing is set, and to drag key be that drag function substitutes key:

Click choosing and drag key, selection area is packaged, and mouse pointer becomes and drags style,

Again click choosing and drag key, packaged content is directly dragged to cursor position;

F key is set and for selecting, drags key selection function correction key:

Without Regional Economy, select operation whether to complete, click F key, have and cancel the selected function in selected region.

Adopt such scheme, the operation of mouse alternative functions will be very convenient, not only solve portable problem, and some of original mouse are also overcome because of the defect producing of performance reason simultaneously, and operating speed and accuracy obviously improve.Wherein mouse moves double speed setting, and the setting of deceleration key and click support are the soul places of mouse function replacement scheme, and it really makes button substitute mouse and moves towards feasible.The realization that the page moves left and right function is the breakthrough to mouse function.Utilize left hand dish to carry out mouse function and substitute, more meet left hand and consult, reasonable life and the work habit of right hand notes.Fig. 2 marks the basic setup of such scheme, for using the personage of this keyboard layout that prompting is provided.

In order to make full use of right hand core keypad, a convenient function is set to each character keys, enabling and cancelling and enable simultaneously and cancel with mouse function state.So, the operational attribute of this keyboard is strengthened.

In the lower right corner of Fig. 2, the left upper right corner of multimedia key, Play/Pause key and Stop key, marks respectively one or two function, and upper left corner function realizes by the participation of shift key, and upper right corner function realizes by the participation of space bar.Forced dormancy function is set in keyboard program, reaches 30 minutes service time and enter forced dormancy, by dormancy pilot lamp, carry out prompting in 2 minutes, Shift+Sleep is set and removes forced dormancy.

This keyboard can carry out Function Extension to other function keys and character keys by similar fashion, and therefore, existing 50 keys have compared with powerful expansion potentiality.

Four-node input method keyboard, it is a kind of kinds of miniaturized keyboards designing in conjunction with four finger conversions according to alphabetical merogenesis input principle, keyboard structure is compact, number of keys is few, be particularly useful for the character keys of letter and word input still less, keyboard layout is applicable to bimanualness very much, is easy to enter touch system state, along with the realization of mouse alternative functions, the performance advantage of this keyboard and portable speciality are fully discharged.By above-mentioned simple introduction, we can find out the practicality of this keyboard and powerful adaptive faculty and as the real glamour place of keyboard of new generation.
