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

One: the principle of substitution:

Utilizing mouse that mouse pointer is controlled, is to be undertaken by computing mouse roller or the mouse displacement with respect to backing plate.Replacing mouse with button, is to come the mouse beacon pointer with changed into the speed that multiply by regulation by time quantum by displacement mouse beacon pointer.

Two: the mouse locomotive function substitutes:

1: the keypress function setting:

Four joint positions of left hand key is set is respectively left, upper and lower, right mouse migration pen travel function key:

Two keys are operated simultaneously and are realized oblique moving;

The function replacement key that subscript key and subscript key are key in the mouse is set:

Pin the subscript key, replace promoting forward key in the mouse,

Pin the subscript key, replace pulling back key in the mouse;

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

Push the subscript key, the page moves on line by line, pushes the subscript key, and the page moves down line by line;

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

Shift key+go up the subscript key is realized Home and End function;

It is web page operation function combinations key that space bar+last subscript key is set:

Space bar+go up the subscript key to click, webpage enters page or leaf or nextpage;

What space bar and A key and U key were set is combined as page move left and right function combinations key:

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 be provided with of mouse:

The time segment length: 150ms, whenever expire a period mouse and move 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 and move 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:

The time segment length: 150ms, whenever expire a period page and move once

Click and support deduction time limit: 250ms

Key moves 0.5mm in per period mouse

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

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

Space+go up the click of subscript key to send page or leaf or following page signal

Move for the first time to betide and click end or expire 400ms constantly

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

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

The time segment length: 50ms, whenever expire a period mouse and move 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 the normal speed state

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

Default conditions: mouse function state

The mouse function state changes input state over to:

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

Input state changes the mouse function state over to:

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

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

Three: the mouse action function replacement:

1: the keypress function setting:

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

Choosing is set, and to drag key be that regional 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, finishes the zone 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,

Click choosing once more and drag key, packaged content is directly dragged to the cursor position;

The F key is set drags key selection function correction key for choosing:

No matter whether the zone selects operation to finish, and clicks the F key, has cancellation to the selected function in selected zone.

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 simultaneously because of the defective that is produced of performance reason, and operating speed and accuracy obviously improve.Wherein mouse moves the 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 of page move left and right function then is the breakthrough to mouse function.Utilize the left hand dish to carry out mouse function and substitute, more meet left hand and consult, the reasonable life and the work habit of right hand notes.Fig. 2 marks the basic setup of such scheme, for the personage who uses this keyboard layout provides prompting.

In order to make full use of right hand core keypad, a convenient function is set, enabling and cancelling and enabling simultaneously and cancel for each character keys with the 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 one or two function respectively, and upper left corner function realizes that by the participation of shift key upper right corner function then realizes by the participation of space bar.The forced dormancy function is set in the keyboard program, reaches 30 minutes service time and entered forced dormancy, carry out prompting in 2 minutes, Shift+Sleep is set removes forced dormancy by the dormancy pilot lamp.

This keyboard can carry out the function expansion to other function keys and character keys by similar fashion, and therefore, existing 50 keys have than powerful expansion potentiality.

The four-node input method keyboard, be to import principle according to the merogenesis of letter to refer to a kind of kinds of miniaturized keyboards that conversion designs in conjunction with four, the keyboard structure compactness, number of keys is few, the character keys that is particularly useful for letter and literal input still less, the very suitable bimanualness of keyboard layout is easy to enter the 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 are the practicality of this keyboard and powerful adaptive faculty and as the real glamour place of keyboard of new generation as can be seen.
