Description

A kind of computer entry device

Technical field

The present invention relates to a kind of computer entry device, particularly the computer entry device that mouse and keypad function are combined.

Background technology

Computing machine generally partly is made up of main frame and peripheral hardware, and peripheral hardware partly generally includes display, keyboard, mouse and miscellaneous equipment, and wherein keyboard and mouse are general calculation machine input equipments.

Keyboard mainly provides keyboard operation functions such as typewriting input and control, generally include framework and button, button often is that the form with push-button array is arranged in the keyboard framework, and keyboard can also comprise the circuit of the operation signal that is used to transmit or handle button and software etc. certainly.In actual the use, keyboard towards also close user's a side, can be referred to as fore side usually.For portable or mobile computer, peripheral hardwares such as aforementioned main frame and keyboard are assembled into one compactly through regular meeting, and the keyboard framework is the main frame framework just, is referred to as the keyboard framework later on.

Mouse mainly comprises indicator device and button click, indicator device moves in order to cursor on the control computer display, button click is a manual switch, in order to carrying out common clicking operation, mouse can also comprise the circuit that is used to transmit or handle indicator device, button click operation signal etc. certainly.

Indicator device is exactly an orientation sensor, and perhaps its core is to point to sensor.Orientation sensor can be measured point operation power or the displacement with direction and size on the suffered two dimensional surface.

When using keyboard and mouse, user's hand will move around between keyboard and the mouse through being everlasting, and influences user's energy and mood, reduces work efficiency.For portable or mobile computer, it is also inconvenient to carry a mouse in addition.

In order to address this problem, often the scheme that adopts is that indicator device and button click are arranged on the keyboard, and user's hand needn't leave keyboard, just can point to and clicking operation.In order to reach this purpose, there is multiple concrete technical scheme to be suggested or to adopt.

1) technical scheme of special-purpose indicator device and button click is set

In the United States Patent (USP) " 5; 600; 313; computer keyboard (Computer keyboard) ", under push-button array, be provided with one and point to the rod-type sensor as indicator device, point to bar (pointing stick) and pass in the middle of G, H, four keys of B, N, the termination, top of pointing to bar is the manual position of accepting user's operation, and the orientation sensor that cursor moves on the control display is equipped with in the bottom of pointing to bar.The user can laterally promote to point to the termination, top of bar with finger, thus the position of control moving cursor.Two buttons (Button) have been installed near fore side near SPACE key on the keyboard framework, corresponding respectively the left and right button of mouse matches with pointing to bar, provides and the similar function of mouse.It is all very thin to point to bar and termination, top thereof, and is clipped between the button, and the operator will point to bar with forefinger or middle finger operation, with thumb manipulation button on the other hand, perhaps uses two hand compounding practices.

In the United States Patent (USP) " 6; 181; 325; have the accurately computer system (Computer systemwith precise control of the mouse pointer) of control of cursor of mouse ", on near the close keyboard framework of the fore side SPACE key on the keyboard, a touch-sensitive plate has been installed, also has been provided with two button clicks against touch-sensitive plate.User's finger paddling on touch-sensitive plate is controlled the position of moving cursor as promoting mouse.On the touch-sensitive plate side the 3rd button is installed also, moves state of a control with meticulous two kinds of cursors in order to switch usually.The shortcoming of this scheme is bigger with the mode of operation difference of using mouse, and more awkward sensation is arranged.

In the United States Patent (USP) " 5; 646; 821; trace ball and button are installed on the portable computer (Portablecomputer with trackball keys mounted on an edge of a computer housing) at body edge ", near close fore side SPACE key on the keyboard framework, a trace ball has been installed, and promptly similarly is the mechanical bobbin type mouse that counter-rotating is installed, and also is provided with button click against trace ball.The user stirs the position that spheroid moves the control cursor.The shortcoming of this scheme also is bigger with the mode of operation difference of using common mouse, and more awkward sensation is arranged.

Here quoting from top three patents is in order to show three kinds of typical solutions, is not to illustrate that technique scheme is exactly that these three patents are initial and invents.

Also has United States Patent (USP) 5,504,502, mobile computer display light target is pointed to control device (Pointingcontrol device for moving a cursor on a display on a computer), has invented a kind of slide block type magnetosensitive indicator device: proposed the multiple structure that the manual part or the manual position of its acceptance operation are designed to be suitable for finger manipulation.This Patent publish this indicator device is arranged on the conception of the different parts on the portable computer, comprising the position that this indicator device and button click together is arranged on the keyboard framework near fore side.In this patent, the user will be simultaneously with forefinger or thumb or this indicator device of other finger controls and button click with use the mode of operation of mouse to still have marked difference.The indicator device of this patented invention has a switch, can use as button click.

2) utilize the technical scheme of keyboard

Also have with the scheme of keyboard operation function and point operation function such as realize simultaneously typewriting of the button on the computer keyboard, in United States Patent (USP) " 5,675,361; computer keyboard indicator device (Computer keyboardpointing device) ", Y, U, H, the top of J key is with the sense of touch film, provide directional signal with the finger slip, other key (such as the F key) can be multiplexed with button click.

The keyboard that is multiplexed with button click is hereinafter referred to as multiplexing button, when carrying out keyboard operation, multiplexing button is operated under the keyboard modes such as original character input or control, after its mode of operation switches to a blow mode, realizes the function of button click under a blow mode.Have multiplexing button just switching device shifter must be arranged, switching device shifter is used for the mode of operation of described multiplexing button is switched between keyboard mode and some blow mode.Switching device shifter generally is in order to the form work of sending 0,1 pulse or 0,1 status signal, can be made of any switchgear.United States Patent (USP) 5,675,361 adopt two keyboards as switching device shifter, it is pressed simultaneously send switching signal.

The another kind of scheme that realizes keyboard operation function and point operation function with the character keys on the keyboard simultaneously, in United States Patent (USP) " 4680577; multi-usage cursor control key switch (Multipurpose cursor controlkeyswitch) ", in the bottom of a character keys orientation sensor part is housed, make this key not only have original typewriting input function, and can laterally promote with finger, control moving of cursor, such button can be referred to as to point to key (pointing key).Improve this sensing key scheme, for the more following several patents that also has that continues and make great efforts is made in the reality use: United States Patent (USP) " 5; 124; 689; integrated keyboard and indicator device system (Integratedkeyboard and pointing device system) ", " 5; 189; 403; have the integrated keyboard and the indicator device system (Integrated keyboard and pointing device system with automaticmode change) of automatic mode conversion ", " 5; 245; 321; have the integrated keyboard system (Integratedkeyboard system with typing and pointing modes of operation) of typewriting and point operation pattern ", " 6; 107; 996, have the integrated keyboard and the indicator device system (Integrated keyboard and pointing devicesystem with automatic mode change) of automatic mode conversion ".In the above-mentioned several patents of this section, point to key and adopt the J key more, and adopt multiplexing button as button click (is button click as specifying D, F key), switching device shifter is the dedicated button switch that is arranged on the keyboard framework, or key is closed judges the signal that sends the multiplexing button mode of operation of switching with time series pattern that disconnects and time length according to pointing to.

Utilize the technical scheme of keyboard, point to key and multiplexing button and all squeeze in push-button array, point to and clicking operation all will be finished and uses the mode of operation of mouse to still have marked difference with finger.

Aforementioned utilization is pointed in the several patents of key, tends to use home key such as J key as pointing to key especially.So-called home key is meant, during keyboard operations such as the input of typewriting as the user of service, often be the right hand from the forefinger to the little finger of toe, be placed in successively J, K, L; On four buttons, these four buttons are right home keys.This putting position of the right hand is the basic operation posture of the right hand, can be called the home key hand position of the right hand.Equally, the home key hand position of left hand is the posture when being placed in its four fingers on F, D, four left home keys of S, A.

3) keyboard adds the technical scheme of mouse

United States Patent (USP) " 5; 936; 555, adopt the keyboard of traditional typing key to combine (Combined keyboardand mouse employing conventional typing keys) with mouse " is in this patent, the bottom that the roller ball or the optical sensing of mouse partly is arranged on keyboard, half keyboard whole or that separate can be pushed as mouse, adopt J, K simultaneously, three buttons of L are as multiplexing button, and a pushbutton switch that is arranged on the keyboard side uses as switching device shifter.Even move half keyboard on desktop or keyboard drawer, therefore the active area too heavy or that needs are too big that yet seems does not see that this technical scheme adopts in actual product.

4) the dull and stereotyped technical scheme that promotes

United States Patent (USP) 6,020,877, the cursor control device (Cursor control devicefor use with computer system) that is used for computer system, be arranged on keyboard near on the framework of fore side with pointing to the rod-type orientation sensor, a flat board consistent with keyboard length (plate) that can promote with palm is set above, point to the bar upper end and pierce in the hole on the flat board, drive it by flat board and move or stressed, in order to moving of control cursor.Between dull and stereotyped middle part and push-button array, be provided with two button clicks.Described platen area is very big, and is relatively poor as the movable part practicality, and must operate the operating effect that just can reach expection simultaneously by two palms.The position that is provided with of button click only is suitable for using thumb manipulation, and still there is big gap in operation posture with the real mouse of use.

5) indicator device type and operation

Existing indicator device can be divided into two classes, and a class is as United States Patent (USP) 6,181, the trace ball that 325 touch-sensitive plate that adopted and United States Patent (USP) 5,646,821 are adopted.The characteristics of this class indicator device are that operator's hand places indicator device, if single job fails cursor is moved into place, must have and leave the action of resetting again, just can proceed operation.Be referred to as to put again the type indicator device below such indicator device.

Another kind of is as United States Patent (USP) 5,600, the slide block type sensor that sensing key that the 313 sensing rod-type sensors that adopted, United States Patent (USP) 4,680,577 are adopted and United States Patent (USP) 5,504,502 are adopted.The characteristics of this class indicator device are under the support of corresponding software, and operator's hand can place indicator device all the time, needn't leave in the middle of the operation again and reset, and just cursor can be moved to any position on the display.Be referred to as often to put the type indicator device below such indicator device.

6) circuit and software etc.

Devices such as circuit to the operation signal that is used to transmit or handle keyboard, indicator device, button click, multiplexing button and switching device shifter, and about software of keyboard, sensing, click and main frame etc., all there are many prior aries to use, or can realize at an easy rate according to prior art, the present invention does not carry out work in these areas yet, therefore repeats no more.

In the aforesaid various technical scheme, though user's hand needn't leave keyboard, it is inconsistent with the use mouse to finish the mode of operation of pointing to click function, needs some exercises to grasp, even or long-term the use also still felt and inconvenience made the people obviously feel like that freely convenient not as using mouse.

Summary of the invention

Embodiment 2:

On the basis of embodiment 1, keyboard is multiplexed with multiplexing button uses as button click, multiplexing button can be for one or more, and button click can be by one or until all being that multiplexing button is formed.

Have multiplexing button just switching device shifter must be arranged, switching device shifter can be various forms, can be arranged on each position of keyboard.As Fig. 1 or shown in Figure 3, for cooperating the employing of multiplexing button, set up the switching device shifter 106 of the mode of operation that is used to switch multiplexing button, generally can adopt the contact button switch.

If with J, K, three buttons of L as multiplexing button, suitably select to point among Fig. 1～Fig. 3 the position that is provided with of device 103, make when the right hand is placed in keyboard operation home key hand position, it is controlled below the palm heel that end 105 is in the right hand just, can control end 105 with laterally promoting this around the palm heel, orientation sensor in the indicator device 103 just can provide corresponding directional signal, in order to moving of cursor on the control display screen.Like this, key hand position just can be pointed to and clicking operation in position, and uses the real mouse of operation posture and use extremely similar.

Indicator device 103 can be designed to a detachable independent device, can be installed on the keyboard, or pull down from keyboard.The edge contour of indicator device upper surface shell 104 can also be other different shape except circle.Also indicator device 103 and keyboard framework can be designed to one.

Switching device shifter 106 can be such independent pushbutton switch among Fig. 1 or Fig. 3, and the operator presses this pushbutton switch, and microprocessor switches multiplexing button between keyboard mode and some blow mode back and forth according to the pulse that this pushbutton switch is sent.Also can choose at least 2 described keyboards as switching device shifter, the mode of operation of described multiplexing button be switched between keyboard mode and some blow mode with its operation of being pressed simultaneously.Such as choosing F, D, three keys of S, send the signal that switches multiplexing button mode of operation with the operation of pressing these three keys simultaneously.Because keyboard when normal typewriting input or control operation, the situation of two or more character keys generally can not occur pressing simultaneously.Mouse the situation of two above buttons also can not occur pressing simultaneously under normal operating position.As switching device shifter, press the keyboard that multiplexing button is switched back and forth simultaneously between keyboard mode and some blow mode, below be referred to as mode switching key.

Although the software workflow of input equipment of the present invention mostly is a prior art, or can realize at an easy rate,, simply introduce a kind of flow process that can adopt below in order to help to understand present embodiment according to prior art.

As shown in Figure 5, program start enters square frame 501, and keyboard microprocessor carries out initialization to each program parameter or variable and part digital circuit, sets the initial value and the original state of work.Wherein S is that the multiplexing button work at present pattern of 0 representative is a keyboard mode, is that the multiplexing button work at present pattern of 1 representative is the some blow mode.Program begins to carry out square frame 502 then.

Square frame 502 among Fig. 5 detects the state of mode switching key in fact exactly, pressed simultaneously and decontroled when detecting mode switching key, then in square frame 503 with the value negate of multiplexing button mode of operation sign S (S non-0 both 1), keyboard is prepared to change another kind of mode of operation over to from original mode of operation.Do not pressed and decontrol this complete operation together if detect mode switching key, it is constant that then multiplexing button is kept former mode of operation.Square frame 504 judges that according to the value of S multiplexing button should enter/keep keyboard or click any mode of operation.

If the square frame among Fig. 5 504 judges that multiplexing button should enter or keep keyboard mode, program promptly turns to square frame 505, by the operation of all buttons on prior art scanning and the explanation keyboard.

If the square frame among Fig. 5 504 judges that multiplexing button should enter or the support level blow mode, program promptly turns to square frame 506, measures and reads the current numerical value that points to the metering circuit signal, and carry out necessary evaluation work, to obtain useful relevant information.

Then program changes square frame 507 over to, reads the state of multiplexing button, and explains the state and the variation of multiplexing button according to the some blow mode of similar mouse button function.Behind the keyboard inlet point blow mode, except multiplexing button, remaining button can redefine its function as required, also can still keep the original function under the keyboard mode.

Final program can turn to square frame 508 from square frame 505 or square frame 507, sends the signal of the button operation that taken place and should transmit to main frame or sensing, clicking operation to main frame.Then program is got back to square frame 502, begins the another circulation of taking turns.

For portable and mobile computer, if processor also will be carried out other operation and calculation task simultaneously, software workflow will mutually combine with it among Fig. 5.

Embodiment 3:

Adopt J, K, three buttons of L as multiplexing button, point to, hand position and keyboard operation home key hand position during clicking operation be identical, though the characteristics that tool needn't frequent mobile arm, but allow the user obscure the current mode of operation of multiplexing button easily, operating mistake occurs, therefore often need ancillary cost energy to distinguish which kind of pattern multiplexing button is under now.Press the mode of operation that mode switching key switches multiplexing button simultaneously, this operation also may someone will dislike.

In the present embodiment, propose a kind of scheme that embodiment 2 has been carried out change, still illustrate below with Fig. 1.

Select the position that is provided with of indicator device like this, make that described control end is near the palm heel, and avoids palm touching it when user's hand position is keyboard operation home key hand position as far as possible.

Such as reference Fig. 1, suitably selected indicator device 103 is provided with the position on the keyboard framework, and suitably to select some button be that multiplexing button is to use as button click, make the control end 105 of indicator device 103 be in such position, when user's hand position is keyboard operation home key hand position, the control end 105 of indicator device is near the palm heel, and avoid palm touching to it as far as possible, when finger places on the selected multiplexing button, the palm heel is in controls end 105 tops, is convenient to this indicator device of control operation.

The sense of touch original paper is set can for multiplexing button, placement or the contact of sense of touch original paper energy perception finger on multiplexing button used as switching device shifter.Such as detect at least 3 multiplexing buttons when haptic elements when contact finger arranged simultaneously, just according to this detection signal of haptic elements, multiplexing button switched change over to or continue the support level blow mode, otherwise multiplexing button is returned to or continues to keep keyboard mode from a blow mode.Certainly the condition of switching working mode also can change at least 2 or 4 into.

The user leaves that keyboard operation home key hand position is gone to point to new position, clicking operation, and the mode of operation of finishing multiplexing button by the change of operator position is automatically switched, and has saved the operation of pressing mode switching key simultaneously.Keyboard operation home key hand position and point to clicking operation hand position and distinguish to some extent, the user can be at any time knows that according to the operator position multiplexing button is in keyboard or clicks under any mode of operation, is not easy to obscure and maloperation.When carrying out keyboard operation, indicator device is controlled the accident of end and touched and to be reduced.

There is several different methods haptic elements is set for multiplexing button,, perhaps the key body itself is designed to have the quick contact sensing functions of power, perhaps button is designed to have the photoelectricity contact sensing functions such as apply dress one deck sense of touch film on the surface of button.

A plurality of described multiplexing buttons can be provided with haptic elements, when detecting wherein 3 multiplexing buttons when haptic elements the finger contact arranged simultaneously, not only the mode of operation of these 3 multiplexing buttons is switched and changed over to a blow mode, also these 3 multiplexing buttons are defined as corresponding button click automatically successively according to from left to right order.This technical scheme can adapt to the size of operator's palm automatically, all be provided with haptic elements such as I, O, P, 8,9,0 these 6 buttons, with reference to Fig. 3, the less children of palm can select to use I, O, these three multiplexing buttons of P, and the adult that palm is bigger can select to

use

8,9,0 these three multiplexing buttons.In like manner, also can with M,＜, three buttons, perhaps F9, F10, three buttons of F11 are chosen as multiplexing button and use.

The process that selection and its mode of operation of multiplexing button are switched can be as follows, at first carry out every initialization, and be keyboard mode with the Working mode set that all have a multiplexing button of contact sensing functions, detect then and judge whether wherein to have at least the haptic elements of 3 multiplexing buttons all to detect sense of touch finger, then all do not keep keyboard mode, have and then select these 3 multiplexing buttons for use and change its switching over to a some blow mode, be defined as corresponding button click automatically successively according to from left to right order.In cycle detection next time,, then continue to keep these 3 multiplexing buttons to be a some blow mode, otherwise its switching is gone back to keyboard mode if the haptic elements of these 3 multiplexing buttons still all detects the placement of finger.Follow-up cycle detection and judgement, handoff procedure be to similar first, be selected multiplexing button can be other.Therefore the remainder of software flow can repeat no more with reference to FB(flow block) 5.

If J, K, three buttons of L also are provided with haptic elements, just selected multiplexing button is returned keyboard mode from clicking mode switch when on detecting J, K, three buttons of L, all having finger to place, the switching judging of mode of operation will be more reliable.

The facility of multiplexing button certain special projection can be set on multiplexing button for the user distinguishes, such as a kick point, or projection is little rectangular, and the user uses the finger touch perception easily.Also can be below multiplexing button or other position of keyboard be provided with the pilot lamp of monochrome, double-colored or polychrome, being used in reference to and giving instructions in reply with selected state or the work at present pattern of button.

Embodiment 4:

Select the position that is provided with of multiplexing button and indicator device as embodiment 3, palm touches when making the control end of indicator device avoid the keyboard operation home key, but change the switch that near indicator device, is provided with as switching device shifter into, indicator device and switching device shifter have the assembly relation of mutual vicinity, can be operated simultaneously by same palm, when palm does not place indicator device, switching device shifter makes the mode of operation of described multiplexing button be in keyboard mode, when palm places on the indicator device, the operation indicator device also simultaneously or at first operated switching device shifter, switching device shifter makes the mode of operation of described multiplexing button be in a blow mode.

Illustrate with Fig. 3, two switching device shifters 106 are provided with near nestling up indicator device 103 on the fore side part 100 in the keyboard framework, switching device shifter 106 is a pushbutton switch, can hold 105 to be operated simultaneously by same palm together with controlling, user's palm places when controlling on the end 105, at first or simultaneously make switching device shifter 106 actions, send the mode of operation switching signal of multiplexing button, multiplexing button switching changes a blow mode over to.The both available thereupon palm of user promotes to control moving of end control cursor, and uses multiplexing button to carry out clicking operation as button click.When user's palm left indicator device, switching device shifter recovered ortho states, and signal procedure switches multiplexing button again and goes back to keyboard mode in view of the above.Two switching device shifters 106 can be two contact change-over switches, also can be optoelectronic switches etc.

For realizing above-mentioned functions better, also switching device shifter and indicator device can be designed to integral structure.The technical scheme of realization integral structure can have multiple, below a kind of design proposal with these characteristics of suggestion.

As shown in Figure 6, wherein 601 is substrates, can be printed circuit board (PCB) or printed circuit board (PCB) and the combining of other plate, and also can be the bottom shell of keyboard or computing machine framework, is used to carry other ingredient that integrated indicator device structure is installed.606 can be any sensor that can experience measurement point operation acting force or displacement, both orientation sensor, substrate 601 or outside framework 602 fixed installations relatively.Because be to be example to point to the rod-type sensor here, so orientation sensor 606 also comprises and points to bar 604.The 603rd, switch handle, this switches the part of handle as switching device shifter, and the control end 105 that is indicator device with its top integrated design makes switching device shifter and indicator device accept the operations such as promotion control of user's palm together simultaneously.

As can see from Figure 6, switch the top framework mesopore that handle 603 passes outside framework 602, be sleeved on and point on the bar 604, can move up and down along pointing to bar 604.Flexible member 605 is arranged on and switches between handle 603 and certain fixed part such as the substrate 601, when palm does not place indicator device, switch handle 603 and promoted, make it to be in the normality position that the top framework of the outside framework 602 of directed device is limited by flexible member 605.When palm places indicator device, switch handle 603 because of being subjected to oppressing downward generation displacement, this displacement be to switch the directed bar 604 of handle to withstand to greatest extent, both closely contact, and at this moment switch the sensing bar 604 that handle 603 can drive as an orientation sensor part and move together.

The outside framework 602 of indicator device is installed substrate 601 relative fixed, and it mainly act as the range of movement that handle is switched in constraint.

The vertical view of parts 602,603,604 can be circular, spring 605 is circle coil springs, orientation sensor 606 can be square, it also can be the circular symmetric shape that waits, therefore the integrated indicator device structure of the present embodiment sectional view 6 that only draws is illustrated, vertical view etc. no longer draws.

Be fixed on an electrical contact 607a and a secondary change-over switch 607 that is fixed on the electrical contact 607b formation switching device shifter on the annular disk 603 ' that switches handle 603 on the outside framework 602, another secondary change-over switch 608, two auxiliary switch that same 608a and 608b constitute switching device shifter are arranged on the left and right sides of switching handle 603 symmetrically.Two auxiliary switch so also can be symmetrical arranged according to front and back position, perhaps by 90 ° of distributions four such switches are set on circumference.When the switching handle is in the normal state the position, aforementioned change-over switch closure, when change-over switch moved down, aforementioned change-over switch disconnected, therefore can detect the location status that switches handle with change-over switch, and switch the mode of operation of multiplexing button according to the variation of the state of change-over switch.

On structural design to this integrated indicator device; when switching handle 603 is in the normal state the position; the formed slit 611 of mesopore inwall of its outer wall and outside framework 602 top frameworks should be enough little; only however influence switch moving up and down of handle 603 and get final product; teeter can not taken place even touch when it is not depressed by palm, protecting sensing bar 604 to make it avoid at this moment being subjected to horizontal promotion yet.The inner chamber that switches handle 603 is a cylindrical shape, and slightly inwardly receive the upper end, and its inner chamber wall energy was entangled the excircle that points to bar 604 when it was depressed, and both are transverse movement together, between tangible radial-play can not take place.The roof and the top of sensing bar 604 terminations that switch handle 603 inner chambers can adopt the material that increases friction, perhaps make some little prominent recessed pits, increase side-friction between the two.The middle hypomere that switches handle 603 inner chambers is slightly loose than the upper end, leave bigger slit between the external peripheral surface of this section inwall and sensing bar 604 when making it be in the normal state the position, even switching handle 603 is slightly touched and shakes, can not make yet and point to the horizontal promotion that at this moment bar 604 is subjected to its inwall.The aperture 612 that switches handle 603 tops is to use for ventilating air.

Slip when operating in order to prevent to use, the top of switching handle 603 is just controlled the surface of end 105 and can be made with anti-slip materials such as rubber, or is made into anti-skidding numb line or dot shape.

When the user will point to clicking operation, finger leaves home key and is placed on the predetermined multiplexing button, the palm heel is pressed in and switches handle 603, just control on the end 105, switching handle 603 is pushed by user's palm and is moved downward, driving two mode of operation change-over switches 607 and 608 all disconnects, both send the multiplexing button of expression and answered the signal of inlet point blow mode, control program can be in view of the above switches the inlet point blow mode with preassigned multiplexing button, and the user is that available its is used as button click and carried out clicking operation.User's palm laterally promotes to control end 105, switches handle 603 drive sensing bars 604 and moves together, and promptly may command orientation sensor 606 is sent the directional signal of moving cursor.

User's palm lifts, and switches handle 603 and is promoted to get back to its normality position by flexible member 605, as long as a mode selector switch closure is arranged, control program is about to multiplexing button switching and goes back to keyboard mode.

Aforementioned integrated indicator device certainly has only a change-over switch, and being provided with more than two is to switch the influence that handle is bumped by accidental mistake in order to eliminate.Switch contact also can be arranged on the sensing bar and switch on the internal chamber wall of handle.

Except that adopting sensing rod-type sensor, also can adopt various forms of orientation sensor such as slidingtype, pendulum-type, the sensitive element of orientation sensor can be quick, photosensitive for magnetosensitive, strain, power, electric capacity etc., and switching device shifter can adopt various switches such as contact, photoelectricity, sense of touch, magnetosensitive, electrostatic induction.

In order to adapt to the palm that the user varies in size, position that can the fixed directional device, give setting program of user, at any time call according to its needs, selected some button is multiplexing button, adjust multiplexing button to the distance between the indicator device, to be fit to less palm operation, selected F9, F10, three buttons of F11 are to be fit to bigger palm operation such as selected I, O, three buttons of P.The working method of option program can for, at first the prompting user presses the button that will select on display screen, after person to be used selects to finish, can confirm by " carriage return " key, or select other button to change again, confirm that until last input " carriage return " key program corresponds to button click by from left to right order with selected multiplexing button subsequently successively.

Adopt present embodiment, the software workflow of microprocessor is very similar to Fig. 5, just changes into detecting to judge whether two mode of operation change-over switches 607,608 have all disconnected, and therefore the remainder of flow process can repeat no more with reference to FB(flow block) 5.
