Description

Integrated easy operating key board

The invention belongs to according under the nature comfort conditions shape of palm and manner, designed one-tenth improvement and the computor-keyboard of integrating.The weight that has palm pad hand and forearm when supporting typewriting on this keyboard.Also be equipped with to shake and defend and the vernier control device, utilize the position of palm and thumb to control respectively, and the keyboard version that provides several to be easy to learn and use.

The background of invention:

Preface: for the purpose of narrating conveniently, all various functions all are referred to as with mark (character) on the application's book regulation (1) key, and the vertical row in (2) key position is referred to as key position, row (column) (3) horizontally-arranged and is referred to as to be listed as (row).

In 19th-century last years of a century and twentieth century early years, employed keyboard for typewriting is mechanical, because typist's skilled operation, the speed that typewriting often takes place surpasses the speed of mechanical motion, thereby causes a kind of fault, is called card key (keyjam).This moment, the typist must be interrupted the typewriting operation, fixed a breakdown, and the keyboard that is stuck is taken apart, and these actions have reduced the efficient and the smooth degree of typewriting again.Therefore at University of Wisconsin-Madison Xin Zhou (Wisconsin), there are timber wholesalers that run publishing concurrently in close Wa Ji city (Milwaukee), and with letter on the keyboard and symbol, the principle of the anti-writing efficiency of being undecided was arranged again.For example, the letter of normal use, be regardless of on the contrary to task as far as possible and move nimble finger and operate or the like, wish that nationality is to slow down the speed of typewriting, to reduce the chance of card key, this keyboard, the version of alphabetical arrangement mode, the keyboard that is called the QWERTY formula is to begin to line up because of the order of keyboard upper left side letter by QWERTY.

Its Hou, typewriter in time transition and develop, by the mechanical type typewriter, step into electrodynamic type typewriter, electronic typewriter, document processor and computor-keyboard.The situation that present employed computor-keyboard does not block key at all takes place.But this out of season keyboard is in the market circulation at present, leading keyboard market.

Classic qwerty keyboard, service efficiency is very poor.Generally speaking, 44 keys are arranged on this keyboard, the key or the push rod of two switch keys and 15-20 other purposes are in order to handle carry, switch mode, the adjustment of paper position etc.Slightly through revising, become the key of four row's patterns with Hou, this keyboard version is passed to all over the world again.

Transition along with the time, the instrument of Data Processing is by typewriter, document processor (Word processors), become the use computer, this moment, keyboard needed to carry out more function and the how dissimilar data of input, increased bond number, and added other control systems, therefore, up to the present except other devices, only bond number has promptly surpassed 125 key positions.Each key often must be carried out more than one task simultaneously.With the switching (shift) that has had on the present keyboard, control (control), atypical (alternative) and other pattern conversions, each key can be carried out the task more than four kinds.

The people that can effectively use the traditional type keyboard of four row key positions has been that number is not a lot of.If add aforementioned numerous and diverse improvement, the advantage that the almost more difficult people of making effectively utilizes these to increase.Therefore, tend to slow down the speed of data input and increase the chance that makes a mistake in the operation.And other computer peripheral device as slide-mouse and rocking bar (joystick), but is helpless to solve the above problems.

Because the purpose of QWERTY formula keyboard Designing is in order to slow down the speed of typist's finger manipulation typewriter, to avoid the chance of card key, therefore, we claim the keyboard of QWERTY formula keyboard for " deliberately being in the way ".

In addition, arrange the keyboard of formula, show out another kind of problem again according to the QWERTY mode.For example, letter is a mark the most frequently used on the keyboard, but on QWERTY formula keyboard, and its alphabetical arrangement mode there is no the sequence rule of any logical property, lacks the keyboard version of sequence rule, tends to cause the user to remember the difficulty of each key position.Therefore we claim the keyboard of QWERTY formula keyboard for " hindering brain ".

In addition, QWERTY formula keyboard, the arrangement mode of key, the be in line row of type of transverse row, it is tiltedly straggly vertically then to be the stepped right side.Row's method laterally in upright arrangement has ignored that five fingers are uneven in length on the palm, and right longitudinally sloping step is straggly, is originally when the design of mechanical typewriter, in order to abdicate a little places, passes through for the lever that connects each key.But the keymap arraying method of vertical right sloping step formula straggly, according to the principle of ergonomics, during but with typewriting, the optimal storing angle of left hand is arranged in the other direction.

In brief, on the QWERTY formula keyboard, the arrangement mode of key is to violate service efficiency (being in the way), (the hindering brain) that finds it difficult to learn, and run counter to the principle of ergonomics (ergonomics).

Past, the someone attempted to correct all inconvenience that is caused by QWERTY formula keyboard always, but all made a futile effort for many years.Because the keyboard of those so-called improvement, all non-friendliness is easy-to-use.Any newly-designed keyboard, no matter wherein have how many otherwise advantages,, then must suffer from the resistance of all user's unanimities as long as originally be exactly the method learning to use of being not easy, comprising the professional person that must use keyboard, the manufacturer of general masses and keyboard.

The keyboard person of being to use desires the mat computer and comes the most important interface tool of processing data.Have new working opportunity more than 75% at least in visible future, need have the technical ability of operating computer.Regrettably, most at present people was trained by formal typewriting never, therefore can't correct and efficient operation QWERTY formula keyboard, must by operation keyboard just can reach the work of task the time, have to take the method for some adaptability in tactics when they suffer from, modal situation is:

1. on keyboard, word for word seek the key position of mark.

2. several fingers only using minority come button.

Now, the world is just stepping into the epoch of computing information, and computer will infiltrate all industries, school and family.Therefore, developing a kind of not only easy operation but also conform with ergonomics, is the keyboard that uses object with the ordinary populace, has become the task of top priority.

The present invention introduces the integrated new keyboard that a cover outclass QWERTY formula keyboard.This new keyboard all has unique distinction at ergonomics, writing efficiency and aspect such as friendly easy-to-use.

The keyboard that a present tool is suitable for must have at least that 5000 bits are above to transmit various information more than at least 100 kinds, comprises letter and graphical symbol, uses for operators such as program design and digital operations.The keyboard that one tool share must be able to allow fast correct input of information, can be compatible with the instrument of various processing information, and must be to be easy to learn and use; The more important thing is that it should allow user's hand channel often remain on the most natural state, to avoid the generation of repeatability compressing injury (RSI, repetitive stress injuries).

The present invention introduces this suitable keyboard, and basically, it is to make that palm turned downwards, and the posture of relaxing with peace places on a piece of paper, again according to the mode of finger nature activity, depict each finger the territory that should control.Next is provided with palm advance expenditure support palm, to loosen the muscles of the arm.Moreover mark (characters) is arranged in the mode that is easy to learn and use, and is placed on left-hand side on the keyboard as A-L and Y, and M-X and Z then are placed on the right-hand side on the keyboard.And the exploitation palm, different parts such as thumb control potential, in order to controlling various operating keys and function key, the rocking bar of conformability and be located at vernier control device in the thumb field.The vernier control device means on the controlling computer screen the movably device of index in the present invention, as trace ball (trackball), and all designs of tactile track pad (touch pad) or tool similar functions.And any can be by manipulation and mobile index, in the present invention, system is referred to as mobile index (or vernier), it can be arrow, any Warning Mark, the finger of sensing, husky mitriform, vertical bar or horizontal stripe or the like are decided on the software of use.Keyboard of the present invention includes left hand branch dish (1eft quadrant) and right hand branch dish (Right quadrant).Coiled separable in two minutes and independent operation.But meet the posture that hand is placed naturally when placing with 25 °～35 ° angles usually most.The structure of keyboard includes by every finger arranges the key group that delegation indulges away at least, formed many vertical cylinders, and at least by the key of five layers of line, the keypad that is woven into.Also can be equipped with the palm pad that to adjust according to hand shape size on the keyboard.Hou is also introduced the guidance of a series of keyboard using method, with friendly and simple and clear mode, how to introduce correct and this keyboard of efficient use to the user.

In the patent documentation of having announced (Prior Arts), the most approaching of the present invention be that United States Patent (USP) numbering 4,824,268 was presented to Diernisse H.V in 1989 years.The main target of this invention is the keyboard that design one tool conforms with ergonomics, make the storing that finger can nature and touch each key on the keyboard, allow every to point frequent being parked on the home key (home key), make the operation of button simpler, easy, fast reach laborsavingly, simultaneously produce still less mistake than any other keyboard.

Another target of this invention is the number of key on the keyboard, under the considering of the ergonomics that meets palm shape, comes input data and control signal with the minimized number key as far as possible.

Another target of this invention is the arrangement of functions such as the symbol, execution, control on the key, be according to the sensitivity of finger, strong degree and finger shape, make so long as favourable and under possible situation, to often comply with the letter that certain continuous order occurs as far as possible, the key mode that is used alternatingly about being arranged to, if this class has the letter that occurs according to continuous order, the method button that can't replace with both sides, then be dispatched to same letter on hand, be arranged to the different fingers mode of button by turns of utilizing as far as possible.In the hope of the operation of button and react the required time, be reduced to the shortest.

Another target of this invention is that the most frequently used information or control mark are assigned on the home key of clever fingers.And general's time information or control mark commonly used is assigned on the home key of second skillful finger.And the 3rd similar mark commonly used is assigned on the next key that the most easily touches.

All keys on the Diernisse H.V. keyboard, only expectation can cooperate the finger and the structure of palm, makes the finger can very natural being placed on the home key, and when pointing action with nature and touch other key positions, the finger of major part still can be parked on its home key.In its design of demonstrating, key is divided into both sides from top to bottom with a virtual middle separated time, every limit all has two groups of above key groups and other to be provided with, and its designed keyboard does not have applicating geometric factor painstakingly to assist its planning keyboard.

The shortcoming of Diernisse H.V. keyboard comprises the setting of not supporting palm, less than the vernier control device of handling by thumb, do not have the key group that can handle by last metacarpus, do not have the rocking bar that can handle by metacarpus down, not have tangible row between key and the key yet and be listed as between relation.Diernesse H.V. emphasizes a kind ofly to assign version according to frequency of utilization for the mark on basis in addition, and the present invention is then towards integrate computer peripheral equipment and simplify aspect such as keyboard version and improve keyboard.

The discussion of ergonomics aspect (Ergonomic Studies)

Traditionally, the keyboard finger manipulation, so mat of the present invention inquires into every finger when the operation typewriter, sideway movement (Lateral movement) and the most natural posture of vertical movement (Vertical movement) design keyboard.Simultaneously, also develop the possibility that the palm different parts is controlled different computer peripheral devices, in the hope of combining as far as possible.

These inquire into demonstration:

1. palm places on the keyboard, the discussion (hand slope on the keyboard) of suitable gradient.

From the position of ergonomics, when hand and forearm place on the keyboard,, should be 25-35 ° of angle with the virtual neutral that extend forward in the health front.This gradient varies with each individual, the left hand and the right hand, and also difference slightly also changes apart from the distance of keyboard with the user.Therefore, the keyboard preferred design becomes detachable left and right two branch dishes, determines that by the user its only position and angle are good.

2. the discussion (Lateral movement offingers) of the finger side direction activity scope that can contain

To point flat stretching, be placed on the highly moderate platform with the most quiet and comfortable posture, the area that this moment, each finger was contained, the field, one's own department or unit (home domain) that is called this finger, each is referred to that side extends the limit as far as possible, and the scope that this moment, each finger was contained is called this maximum field that refers to (maximum domain), middle office by between field, one's own department or unit to the maximum field then is this extended field that refers to (extended domain).Every finger can have several fields, need look the position at this finger place, and decides with other finger relevant positions.

The discussion in finger field demonstrates at the inwardly square gamut of each finger extended field, is that finger tip touches part easily, and therefore the key of being controlled by each finger should be arranged within the scope of respectively pointing field, one's own department or unit and extended field.This Hou, every finger are according to this ergonomics, and the zone that this finger of planning out touches easily (i.e. the zone of being made up of field, one's own department or unit and extended field) is simply referred to as the field (domain) of this finger.

3. the discussion (Verfical movement of fingers) of finger vertical direction manner.The length of five fingers of every hand, the complexity when strong degree, sensitivity and button are all different.The mode according to the vertical direction activity under state of nature of every finger (i.e. finger stretch bent movable) is to be benchmark according to each finger center line.

Stretch the result that Qu Yundong inquires into by finger, learn the key group that every finger is controlled, preferably arrange along the center line of this finger.In other words, within the field that every finger is contained, the vertical arrangement of Zhu Jian should build up cylinder.

4. the affirmation of home key position (home key location) places hand on one plane, and each finger is under natural and the most comfortable situation, and is slightly crooked, and the position that this moment, each finger tip was parked should be this and refers to best home key position.Therefore, from considering of ergonomics aspect, the mode of home key line should be followed finger length difference, lines up curve.And should be as the line of the orthoscopic that present keyboard adopted.

5. other key of the determining of other key positions (Other Key Locations), then be added in home key above or below, the vertical cylinder that builds up.The bond number that every cylinder (being the field) can hold is decided on the size of this length that refers to and key.

With three fingers of central authorities on the palm, the space of its home key top can hold a key position, and the below of home key then can hold three key positions.

Little finger of toe refers to short dactylus than central authorities three approximately, so the below of its home key is put a key position less.In like manner, thumb is fit to control the key group of three layers of line.

If needed, to dwindle 1/4～1/3 again be the easement and the accuracy that can not influence operation to the still comparable existing general key of the area of key.When desiring to dwindle the area of key, can only dwindle the height of key, and should not dwindle the width of key, the width of key should be pointed slightly wide with wide or ratio with finger.The height of each key then can hold the key of a line if shorten 1/4 more on the keyboard.The height of key then can hold the key of two lines if shorten 1/3 more on the keyboard.

Key on regularization (the Regularity in key arrays) keyboard arranged of key position should have clear and definite row (vertically, column) with row (laterally, relation row).The relation of this regularization, help the user can find rapidly and accurately want the position of the key looked for.Can make the work of memory keyboard version, become more or less freely.

Up to the present the narration of keyboard Designing process, has only vertical arrangement of key to build up cylinder, form the relation of " OK ".But do not set up any transversely arranged relation as yet.Then can design keyboard on if with horizontal keyway (key gaps) between each key of relative height in each field, be linked to be level and smooth curve this moment, the relation between each key on transversely arranged.

The key group (The thumb keys) that controls of thumb present popular keyboard, the both hands thumb mainly is to be used for by a carry key (space bar).In fact, thumb is a not only strong but also finger flexibly.When the thumb finger tip is done the plane motion of side direction, can scanned sizable a slice sectorial area.In this a sheet of fan-shaped thumb field, should be able to hold many key positions.

The thumb field that each is fan-shaped, vertically upright cylinder, the key position that is woven into are complied with in can be suitable be divided into by three layers of key and four lines according to the curve line.The vernier control device (Cursor controller) that is equipped with on the present computer, for example trace ball (track ball) or track pad (track pad) give reservation, are responsible for controlling but change by thumb.Simultaneously the vernier control device on the keyboard of the present invention is two pieces, but not one piece, about branch dish thumb can respectively handle one piece.Thereby the selectivity that application software controls is increased, allow the more handy computer of user, to promote the control ability of keyboard to computer.

8. the key group who is controlled by palm part (The palm operable keys) goes up the position (be on the anatomy metacarpal bone link to each other with phalanges near the joint position) of the palm, the action key that can mat presses down.But at most only be fit to be provided with three key positions herein, constitute a row palm key field.

The position and the mode of operation at palm key place, with different by the position and the method in each its field of being controlled of finger control, and not conflict mutually.Owing to when handling palm key, do not influence the control ability of five fingers to each key in its field.Therefore slap the operating key that key is fit to be designed to a series of switching regulator (for example switch key etc.).And three palm keys can provide eight kind (2 ³=8) the different key formula of controlling.

9. integrated control pad (The integrated joypad) is the metacarpus position down, though be not suitable in order to button, available its passed object.Simultaneously, about 50 ° rotation can be done by the wrist joint place.

With regard to considering on the ergonomics, if a mat that supports palm (or wrist) is set, the comfort in the time of can increasing typewriting also can reduce fatigue.When pad design palm, its position and shape should be not disturbing the operation of digital and palm key, and not make wrist bear any pressure be principle.Therefore on the left and right branch dish of keyboard, each settles one piece of palm pad that closes with following metacarpus position lining.Rocking bar (joystick) can be incorporated into the below of palm pad, handle the motion of rocking bar in the mode of passing with palm, simultaneously, utilize the ability of the rotary moveable that wrist joint has, also rotary inductive device (circular motionsensor) can be incorporated into the below of palm pad.The number rotating disk that old-fashioned finger is dialed is a good example of introducing rotary inductive device notion.This Hou, this integrated palm pad is referred to as to control pad (joypad, or control pad).When pad is controlled in same operation, can't interfere with palm key and digital controlling to each key in its field.Therefore all above-mentioned equipment also can combine and can control synchronously and do not disturb mutually.

So far, keyboard of the present invention has can divide left and right two minutes dishes that unload, so that be placed in the virtual neutral of extending with the positive face forward of health, be 25 °～35 ° angle, and the vernier control device of two covers is arranged, and integrated control pad, on the branch dish that every limit hand is controlled, be equipped with a cover.

10. overseas key group (The power-reach keys) is in order to make typewriting task comparatively comfortable and light, the present invention wishes user's hand, can be frequent be parked in controlled on the pad, the user needn't can touch from hand key far away in order to want, and often hand must being removed on the pad from controlling, so preferably concentrated being located at below the finger in the position of key.Because it is limited that palm can be provided with the area of key position down, and the number of newly-increased key constantly increases on the keyboard, therefore, must set up extra key position outside each basic field, the user can pass the control pad by palm, assists finger can touch these keys.Because these keys are provided in a side of outside each finger field, so be referred to as overseas key position (power-reach keys).

Because the user can use palm and pass control pad, make finger can structure obtain key on the overseas key position, therefore in whole typewriting process, hand must not removed and control pad and come button.

The research of mark (character) method of distribution

The definition of mark: so-called mark means title, symbol, figure, action, the abstraction of any artificial appointment in the present patent application, all may represent it with certain mark.So definition has comprised letter, phonetic symbol, literal, numeral, punctuation mark, synoptic diagram, control (key), function (key) or the like.

1. mark various strategies of assigning

The mode that mark is assigned, one to being one of important issue on the keyboard Designing.The present invention regards it as main subject under discussion.Different mark methods of distribution respectively has its purpose and epoch background.We are divided into four big classes according to the strategy that mark is assigned:

A. disturb the strategy of finger: the assignment of mark on the keyboard, the finger that deliberately disturbs the typist is used the chance that reduces the card key to relax the speed of typewriting.The keyboard at present leading typewriter and computor-keyboard market almost is according to disturbing the designed keyboard that goes out of finger manipulation strategy entirely, and this keyboard is because mark is assigned irregular.To the people who just learns to type, often because of memory keyboard version difficulty produces sense of frustration, so it has also disturbed the reaction of user's brain to the cognition of key position simultaneously.Any irregular mark is assigned, thereby produces the keyboard that difficulty is gone up in the memory of key position, all is considered as to disturb brain (keyboard), comprises QWERTY formula keyboard.

B. the strategy of assigning according to frequency of utilization: it is to be principle to increase writing efficiency that mark is assigned.The assignment principle of mark on keyboard mainly is the intensity that respectively refers to according to the frequency 2. that 1. marks use, and the complexity 3. of flexibility ratio and button speeds any effective method of touching speed.

Say that from writing efficiency this class keyboard is excellent than QWERTY formula keyboard, but because of the assignment of its mark, still lack regularly, cause interference equally brain.

C. easy-to-use with friendliness is the strategy of assignment: the assignment of mark is can allow the position of each key of cognition that user's brain can be very fast.The arrangement of literal or numeral for example is if then meet friendly easy-to-use principle possibly according to the order of letter and the order of numeral.The assignment of mark can be for following if having certain regular logic, can allow the position of each key of cognition on keyboard that the user can be both easy and fast, and needn't word for word search on keyboard.

D. the strategy of assigning voluntarily: use this strategy, then need the application software that will have a cover keyboard to assign voluntarily earlier.Allow the user can be, assign any mark voluntarily to the keyboard on any key position according to the wish of oneself.This method of distribution is more individualized, also allows the user that more choice can be arranged, and the user can be from a series of predefined keyboard versions, optional one, QWERTY for example, DVORKOK (United States Patent (USP) numbering 2,040,248), As Red Hot (United States Patent (USP) numbering 5,498,088) or Sciengifie format (United States Patent (USP) numbering 4,718,736) or the like, or the user can comply with individual special requirement, creates its keyboard version certainly.

2. to this invention is intended to design a cover easy-to-use with friendliness be the keyboard of principle to the mark assignment strategy of classification subregion, can be by the popular keyboard version of accepting.Take into account ergonomics principle and writing efficiency principle in the design, allow the professional person who uses keyboard also be willing to adopt.

In order to reach above-mentioned three principles, make the mark assignment strategy of a cover with the classification subregion.The mark assignment strategy of this classification subregion be with frequency of utilization assignment strategy and friendly easy-to-use assignment strategy the two advantages together.

Classification (The groups): the mark that needs are assigned on the key is classified according to the function of each mark earlier, more all kinds of marks are discharged priority according to frequency of utilization.

Subregion (The blocks): each the key position on the keyboard, according to the complexity of controlling the finger button by it, rating.

Complexity according to this button, add other consideration, as the foundation that keyboard is divided into several keypads, again with all kinds of marks, according to the priority of being discharged, transfer to different keypads, from the mark class (as English alphabet) of the most normal use preferentially be assigned to the strongest and flexibly finger (i.e. Zhong Yang three fingers) on the keypad that marked of the easiest key group who touches (being home key) (being high frequency region), the rest may be inferred by analogy.

Should be regarded as the mark class of the most normal use as for that class mark, preferably be decided in its sole discretion by the user, the size of each keypad area then decide on what of such mark number, and the external form of keypad is then decided on the method for mark arrangement.If a certain mark class number is too much, a keypad can hold any more, then may be partitioned into several sections, more every section is pushed in the different keypads in regular turn.If a certain class mark does not have generally acknowledged order, then the assignment of its mark is easy-to-use based on friendliness, and be aided with other and consider, as the frequency of using, the degree that finger touches easily, whether whether be to be made into right mark, be symmetry or the similar mark of outward appearance, whether have cooperative relationship or the like.These are considered is with deciding in the keypad of a certain mark under it, should be assigned on what position, also determining alloting of its adjacent key position mark simultaneously.

Classification subregion (assignment) strategy (Group-block shategy) though be the term of new wound, but old idea, even some keypad on QWERTY formula keyboard, the assignment of mark also is the principle according to the subregion of classifying.

Keyboard according to letter and numerical order are arranged should not be regarded as inmature idea.This row's method produces the keyboard version that has distinct rule and be simple and easy to remember probably.As arranging according to letter and numerical order, so that the rapid and efficient books document that searches never is regarded as inmature arrangement method with the catalogue in the library.Simultaneously row method and the processed data shown arrangement mode that go out of letter or number on keyboard there is no direct relation.No matter be line in regular turn or stringer in regular turn, or do successional in regular turn assignment with overall unification, or the assignment of segmentation branch cover and branch dish, the most important thing is whether resulting result is correct and meets expectation.Recall QWERTY formula mark ranking method, both made the brain that is in the way of doing it on purpose, but use this keyboard to come the resulting result of processing data, also all be correct usually, and meet user's expectation.

3. the mode that mark is assigned on the one-handed keyboard

Under present working environment, use one hand to come operation keyboard to become normality.This working background has been brought up to be needed to make the keyboard that is applicable to one-handed performance, replaces the business opportunity of operating QWERTY formula keyboard with one hand.

Key on the keyboard preferably is located within each scope that can administer of finger, i.e. the below of palm, but that palm can hold the area of key position down is limited, and on the computor-keyboard of a standard, have 100 key positions at least.Both having made wherein has many keys to cancel or substitutes (as numerical key two covers being arranged, many digital function keys, and the software that available journey such as character code function key is established replaces it) with other method, must be arranged into that the number of mark is the right area that surpasses hand far away on the keyboard.If want to make the mark of enough numbers under holding on the single-hand operated keyboard, can consider following several solution:

1. increase the number of operating key (control keys), for example left and right branch dish switch key, on/following lattice font switch key, and the method for operating that increases cooperation key formula.

2. dwindle the area of each key, so that hold more multi-layered key (preferably the height with each key shortens 1/4～1/3).

3. can set up more key position in overseas district, promptly the zone outside the field that each finger is administered needs mat to promote to control pad, the zone that finger just can touch.

Keyboard of the present invention, except meeting ergonomics, about the branch dish, Shang Kefen unloads, and is fit to one-handed performance.Because design has been taken into account above-mentioned three schemes the time, so be good than the one-handed keyboard of otherwise designed special use.

The guide (Typing Guides) of study typewriting: typewriting is the coordination between a kind of brain and the hand.Want and can typewrite, at first brain must be able to be remembered the tram of mark on keyboard, and secondly brain must command suitable finger to remove button, and once more, when finger pressed the wrong button, brain must have consciousness at once.

For hope can help the user to reach above-mentioned brain and the Coordinating Activity between the hand with simple, easy, correct and efficient method, thereby a series of guides friendly easy-to-use have been designed to the study typewriting.

1. the tram in order to allow the user learn various marks as early as possible can be with various mark groups' keypad, on the framework that distinctly is indicated in the computer screen of classification subregion, as the open-and-shut control reference of a kind of energy.

2. in order to indicate the user with correct fingering operation keyboard, with the key group of different field on the keyboard, utilize the color and the order of rainbow, through look as a means of identification.

3. in order to allow the user when pressing the wrong button, can be alerted at once, the image of the keyboard version that dwindles can be presented on the computer screen, and it is tried one's best near the vernier of subject application software, allow the two concentrate within the same visual field, and the image energy that makes keyboard is with the same moved further of the vernier of theme software.When user's button, relative keys position or mark on the image keyboard in the computer screen can have the demonstration of anti-white (highlighted) at once.Therefore, when pressing the wrong button, anti-white on the screen can find via vision at once, in fact, as long as the keyboard image that can have a width of cloth to dwindle on the computer screen, and mixes the software of audiovisual alert news, promptly is enough to effectively reach all above-mentioned effects.

To the people who just learns to type, still have a kind of simply, easily and the shortcut that effectively practices at typing.

Promptly allow the learner learn earlier to handle the key in the high frequency region on the keyboard with three fingers of palm central authorities.Because high frequency region is for the mark (such as the letter in the English) of arranging the most normal use and the keypad that marks especially.When the user has been familiar with the operation of high frequency region, add key beyond the high frequency region again when operating simultaneously, will feel association's typewriting, be the process that quite is easy in fact.

During this keyboard Designing, however the consideration of ergonomics aspect be according to the structure on the anatomy of human body forearm, palm and finger and when the operation keyboard from comfortable mode of motion.The result of this research shows, when hand placed on the keyboard, when forearm and hand, when being 25 °～35 ° angles with midline of body, sense peace was relaxed.

Therefore keyboard should be respectively equipped with left hand branch dish and right hand branch dish, and each places both sides on the keyboard to be 25 °～35 ° with the body center line, to reduce the tension force that hand and forearm were born.The key group that every finger is controlled acts in accordance with from this and refers to line style activity direction under state of nature.The design of this Improvement type, when the traditional type keyboard typing is used in the improvement that can show, the injury that is caused easily.

With the palm facies palmaris up, draw a straight line, see again and look into each finger and stretch bent movable direction along every finger central authorities, this moment discernable every finger to stretch Qu Yundong be that finger center line along this finger is a benchmark.

, observe the shape of palm with the palm facies palmaris up, the five fingers are uneven in length as can be seen.

1. little finger of toe is than nameless dactylus.

2. nameless than short 1/3～1/4 dactylus of middle finger.

3. wipe the longlyest in, be positioned at the central authorities of hand.

4. forefinger is than short about 1/2～1/3 dactylus of middle finger.

5. thumb position is minimum, and its finger tip only reaches dactylus 1/2 place of Hou of forefinger.

If the length of little finger of toe and middle finger is done a comparison, the finger tip of little finger of toe only reaches 1/2 place of middle finger.Therefore work as little finger of toe with slightly crooked posture, when being parked on its home key, then shorter than middle finger.On traditional keyboard, the horizontally-arranged mode of key is linear line, when little finger of toe slightly crooked be parked on its home key the time, other three fingers then must be done significantly crooked, could cooperate little finger of toe, are parked in respectively referring on the home key on the same parallel lines.The present invention is then for more claiming the keyboard of hand, can allow finger, naturally and touching smoothly.When its method refers to the home key horizontally-arranged for each, its horizontal linear along same is arranged.This through improveing and meet the keyboard of ergonomics, its layout strategy is according to following step:

1. allow the user,, hand is placed big opening on the blank paper with the typewriting posture of comfort.

2. the gabarit of describing forearm, palm and each finger is on this paper.

3. with between the user right-hand man, on the paper of central position, health front, a perpendicular line draws.

4. draw one and walk extension straight line, the perpendicular line of itself and the positive central authorities of health is intersected through middle finger by the forearm central longitudinal, thus method desirable arm and palm when operation keyboard, due gradient and angle.

5. measured gradient is the gradient that the palm orientation conforms with ergonomics.Measured angle usually and health central vertical line be 25 °-35 ° angle.But the size of this angle, the left hand and the right hand are slightly different, and be simultaneously also slightly variant because of the people.

6. respectively refer to the most natural and comfortable posture, slightly crooked, with find out home key on the keyboard the optimum position that should be provided with.At this moment, above each finger tip with below, each draws a strigula, surrounds a square.This square then is this home key that refers to.

7. stretch Qu Yundong with above-mentioned finger, the position that finger tip touched (i.e. the place of the finger mark of laying) finds out the appropriate location of keys such as respectively pointing the upper, middle and lower and the end.

8. around finger mark positions such as selected basis, upper, middle and lower and the end, the scope of drawing boundary line is exactly this place, digital position.If necessary, can also same method, below the key of above the upper key or position, the end, create more key position.

9. the square of drawing according to last method changes and plots the curved arrangement outward appearance that can be connected (be non-with the parallel horizontally-arranged of horizontal linear), causes new transversely arranged relation.In other words, on the upper strata (upper row), this layer (home row), middle level (middle row), and all keys of lower floor (lower row) and bottom (bottom row), with the curvilinear style horizontally-arranged, but not with the orthoscopic horizontally-arranged.

10. in this way, the little finger of toe profile of being depicted, the area that it is inner is referred to as the field, one's own department or unit (homedomain) of little finger of toe.Open to the limit little finger of toe is as possible outer, draw the profile of little finger of toe again, the area that it is inner is referred to as the maximum field (maximum domain) of little finger of toe.Little finger of toe is placed the position of field, one's own department or unit and maximum field central authorities, describe the profile of little finger of toe again, the area that it is inner is called the extended field (extended domain) of little finger of toe.All abbreviate " little finger of toe field " (pinkie-finger domain) as by the area that the little finger of toe extended field is comprised to field, one's own department or unit in hand.

11. nameless field (ring finger domain) has comprised field, an one's own department or unit and extended field.Nameless extended field is above the little finger of toe finger tip.This zone, if when controlling pad, little finger of toe can't touch, but but the nameless then mode of mat sideway movement is touched it.

12. middle finger has only field, an one's own department or unit.

13. forefinger can generally stretch out like little finger of toe, in like manner, its extended field be positioned at by maximum field to centre, field, one's own department or unit half distance.Therefore, so-called forefinger field (ring finger domain) is made of jointly its field, one's own department or unit and extended field, and this refers to control the vertical row's of two row key group.

14. depict the profile of thumb under quiet and comfortable posture.Area in it is the field, one's own department or unit of thumb.Thumb side is outwards reached greatest limit, and describe its profile, its inner scope is the maximum field of thumb.In field, thumb one's own department or unit and half part of maximum field, be its extended field.The scope of thumb activity still can comprise in the thenad crooked in addition.Inwardly till the metacarpus, having contained the sizable area of a slice by the thumb extended field, is to be thumb field (thumbdomain).

In this zone, thumb can touch any key in its field very smoothly.Because this regional profile is quite like 1/4th of circle, so it can be considered as the field (thumb-quarter domain) of 1/4th quadrant areas that scanned by the thumb sideway movement again.The arrangement of thumb field internal key, the camber line of the quadrant that is streaked when then following the sideway movement of thumb nature is arranged.So its internal key group's arrangement mode is not square or the strip that horizontal or vertical direction is arranged.

The vernier control device is trace ball for example, should be incorporated on the keyboard, and its optimal integration position should be that being placed on originally is the position at thumb home key place.The present invention has two pieces of vernier control devices, and every thumb is responsible for controlling one piece of vernier control device.

The vernier control device also is the place of parking as the thumb finger tip.When thumb is parked on the vernier control device, can't trigger moving of vernier.Have the palm key (being set at the operating key of vernier control device) that will be positioned at below, little finger of toe field only and press down, when handling the vernier control device again, vernier is moved.

Utilize the vernier control device,, also belong on this keyboard Designing, one of unique place as the place of parking thumb.The tension force that these characteristics help other four fingers of mitigation to be born.Another only part then is the palm key place below little finger of toe, is provided with the key of control vernier control device switch.

In the design of this keyboard, in the field of palm key, a row palm key is arranged.First palm key is the operating key of vernier control device, is positioned at the below in little finger of toe field.Second palm key is positioned at the below in nameless field and middle finger field.The 3rd palm key is below the forefinger field.But these palm key mat software designs become program key, via the switch motion of its different key formulas, control the choosing house of specific program.

Supporting the mat of palm (promptly controls pad, joypad) also is one of unique place of the present invention.The typewriting posture of standard requires typist's forearm necessary unsettled, and finger fingertip is parked on the home key, though the efficient with this posture typewriting is good, but violate the principle of ergonomics, the posture of this typewriting can cause shoulder, the unsuitable pressure and the tension force of arm and hand.For many frequent people that need operation keyboard, as the secretary, writer and computer programming person etc.This unsuitable pressure is their professional a kind of obstacle.At present several products that relaxes this unsuitable tension force are arranged on the market, comprise the rubber that can fill up under wrist or the mat of sponge matter.On keyboard of the present invention, be equipped with a kind of specially designed palm pad, to relax the sense of fatigue of hand and wrist.

This palm pad is with the function of rocking bar (joystick).The user can not reach the action of handling rocking bar with the mat of this support palm.Therefore produced " controlling pad " new terminology (joypad).Control the shape of pad, should agree with mutually, make when palm is settled thereon, or during its manipulation rocking bar of mat, comfort is arranged all with the shape of the facies palmaris of the palm down.Control pad and be provided with positioning spiral shell button (adjustable screw).Can be by this according to user's staff shape size, adjust by the control pad and refer to the home key to each, can allow and respectively point comfortable best touching distance.

The control pad of newly establishing still includes following unique distinction:

1. both hands often are placed in and control on the pad, support palm and wrist with it, to reduce fatigue.The key (being digital) of useful finger exercise control, the key of controlling with palm (promptly slapping key) and other control device (being letter key, numerical key, vernier control device, rocking bar, rotary inductive device etc.) are all at hand easily within the scope of control.

2. the pattern of this design can cause the effect of " three-point fox method ".Traditional typewriting operation, requiring to have a finger to be parked on the home key at least, so that other fingers can be correctly and get back to rapidly on its home key touching Hou.The method of this operation keyboard is referred to as " some localization methods ".But during the designed keyboard of operation the present invention, palm is often to be placed in to control on the pad, thumb then is often to be parked on the vernier control device, little finger of toe also is often to be parked on its home key, by means of this " three-point fox method ", can increase degree of accuracy and efficient that keyboard is controlled, in the time of also can avoiding picture operation with traditional typewriter simultaneously, must produce uncomfortable tension force and the injury that is caused by the suspention arm.

Rotary inductive device (circular motion sensor) can be incorporated into the base portion of rocking bar.From a structural point, rocking bar only can do along X-direction with along the moving of Y direction (promptly forward, to Hou, to the left and right sides), or according to these two kinds of mode of motion, in conjunction with and the continuous action of formation (as shake, shake to the right Hou side etc. again) to the left front.In the structure of rocking bar, do not have the mechanism of rotary moveable.But people's wrist but can be done the rotation of about 50 degree flexibly.Therefore can consider to install the rotary inductive device additional, so when using the control pad, can feel more smooth-going and more handy at the base portion of rocking bar.In addition, install rotary inductive device Hou additional, can improve the excitement of electronic game, make its more lively, strong and stimulation.

It is several to arrange the keyboard version that strategy is produced in regular turn that the present invention also provides, promptly according to the mark assignment strategy of classification subregion.Assign the experience that the mark strategy is failed in view of many in the past according to frequency of utilization, mark is arranged on the display keyboard needs clocklike importance and practicality.

Mark on the keyboard, the mode of arranging according to systematicness has two classes:

1. the space of a whole page of horizontally-arranged is applicable to Western Culture (as the U.S., Europe etc.).

2. the space of a whole page of vertical setting of types is applicable to oriental cultural (as China, Japan etc.).

We introduce the keyboard version of two kinds of horizontally-arrangeds earlier herein:

1. unified totally formula is the horizontally-arranged method in regular turn: the horizontal letter of left hand branch dish and right hand branch dish being done unitarity is assigned, and is about to a whole set of letter, begin by left hand branch dish, and laterally arrangement in regular turn, and cross right hand branch dish, do successional assignment.

2. divide disc type half position mark horizontally-arranged method in regular turn: with a cover letter in two, preceding half cover (being A-L and Y) laterally is assigned on the branch dish of left-hand side in regular turn, and Hou half cover (M-X and Z) laterally is assigned on the dexter branch dish in regular turn.

We also design the version of several vertical setting of types simultaneously, for use in the language or the phonetic symbol of straight book formula.In fact, in the time of if necessary, any language, letter or phonetic symbol be vertical setting of types in regular turn all.If the version of being discharged is not only logical, and helpful to the memory of keyboard version, then effect is better.

Another kind of have an optionally allocating method, is to allow the user can be according to a human needs its " individual's " keyboard version that is ranked voluntarily.

Divide disc type line method in regular turn, with a cover letter in two, on the branch dish of every limit, assign half cover letter, line in regular turn.

The advantage of this keyboard version is:

1. memory easily

A. letter is docile and obedient preface and is assigned on the key position, and the keyboard version is remembered easily.

B. half cover letter (A-L) is assigned to the branch dish of left-hand side before, and Hou half cover letter (M-X) is assigned to dexter branch dish.

C. vowel letter A, E, I on the branch dish, comes in the same cylinder (being stringer) leftward.

D. vowel letter O and U accompany the diagonal line arrangement of R with central authorities.(annotate: R is one of five the most frequently used consonant letters).

2. this row's method but is perfectly in harmony with arranging the resulting effect of method according to high frequency of utilization.

All assign the letter on home key, except that Q, nearly all are high frequency of utilization letters.

Following table is a branch disc type horizontally-arranged method in regular turn, about the ordering of branch dish letter, and Michaelis (Milliken) and Maxwell (Mc Gunnigle) calculated each alphabetical frequency of utilization according to statistical method, list and do a contrast and relatively.

Table one, English alphabet frequency of utilization statistics are relatively

Can learn by last table, the keyboard version of this row's method, its this layer key lists, and the frequency (44.5～46.6%) that letter uses is greater than upper strata key row (35.7～36%), and (the upper strata key is listed as then) is greater than middle level key row (15.4～17.5%).Row's method of this alphabetical line is added up alphabetical frequency of utilization with Michaelis and Maxwell and the keyboard version of discharging is perfectly in harmony.Also the letter on the keyboard of advocating with Michaelis and Maxwell is arranged, and should make balanced distribution according to the flexibility ratio of finger and work for mutually and close, and demonstrating this is a kind of equilibrium, and conforms with the mark allocation scheme of ergonomics.

3. can promote operating efficiency

When a. using keyboard, most actuation of keys is to be operated by three fingers (being forefinger, middle finger, the third finger) of hand central authorities, and these three fingers also are three very strong in hand fingers.

B. the letter key on the keyboard only has three layers, is arranged in the zone best on the keyboard, and in this zone, key row in upper strata are being close to this layer key row with middle level key row, and its purpose is that letter is concentrated in the very little zone as far as possible, with controlling of convenient letter.In brief, " all English alphabets are only lined up three lines, and are only controlled by every three fingers on hand ".When using traditional Q WERTY keyboard operation letter key, need with four fingers (promptly comprising little finger of toe).The position of some key is difficult for being touched by finger on the keyboard of traditional type, and therefore, as if the arrangement that designs letter according to frequency of utilization, Shang Qing has and can be willing to.In the present invention, all letters, three layers of only lining up the next-door neighbour, and only operate by three fingers that are suitable for typewriting most, make that all letters are touched equally easily.Real in this case unnecessary consideration is arranged letter according to frequency of utilization, because the same difficult note with QWERTY of this row's method finds it difficult to learn.

4. can realize the target of single-hand operated keyboard in the mode of easy economy

This is the branch disc type function of a uniqueness being had of horizontally-arranged method keyboard in regular turn.Its advantage is as follows:

The typewriting operation of standard needs both hands and usefulness, with present scientific and technological level, if desire designs a kind of software of single-hand operated keyboard, is easy to do.Single-hand operated keyboard, can design according to following consideration:

A. Quan Tao letter and punctuation mark commonly used are placed on the keyboard of an one-handed performance (for example, only using the branch dish of keyboard left-hand side) entirely.Figure 37 is one-handed keyboards, and the example of a complete set of English alphabet and numeral is arranged on it.

Key on the keyboard is square or the rectangle of 2cm normally.According to the area of measuring the finger tip below, and the result of the finger mark of being got with varying strength button assessment, we think if necessary, and the area of key still can dwindle 1/3 (promptly shorten height but not shorten width), vacate a little places and allow and can increase more key position on the keyboard.Simultaneously, when the area of key dwindles (promptly highly shortening) Hou, it is closer that the distance between key and the key becomes, and the action meeting of button is faster and more smooth.

The area of key is dwindled on the keyboard of Hou, can hold the key position more than 50 at least.Add the palm key that can control synchronously, control pad, vernier control device etc. can significantly promote the function of this one-handed keyboard.

B. two and partly keyboards (please refer to the branch disc type and partly overlap mark horizontally-arranged method in regular turn) that overlap alphabetical version.With a cover letter in two, preceding half cover is arranged in left hand branch dish in regular turn, and Hou half cover is arranged in right hand branch dish in regular turn.Promptly half cover letter (A-L and Y) and half cover numeral (0-4) and one group of punctuate are assigned on the first-hand keyboard version.The letter (M-X and Y) of half cover and half cover numeral (5-9) and a class symbol in addition in addition are assigned on second-hand's keyboard version.

When desire becomes second-hand version with the version on this keyboard by first hand version conversion, must be earlier by the special function key of next piece (being a left side/right hand branch dish version switch key) referring to Figure 38-39.When unclamping this function key, the version on the keyboard can gain first-hand keyboard version automatically at once.The single-hand operated keyboard that only can show half cover letter on the keyboard version.The letter mode of horizontally-arranged in regular turn has two kinds, and row's method of branch dish branch shell type (is A-L and Y, is placed on first-hand key face version, M-X and Z are placed on second-hand's key face version) (be A-D than the method for horizontally-arranged in regular turn (referring to Figure 28) of overall unification, I-L, Q-T comes on first hand keyboard version; E-H, M-P, U-X come on second-hand keyboard version) to remember easily many.The keyboard of vertical setting of types keyboard version in regular turn, can be one-handed performance or bimanualness, its row's method can be docile and obedient preface from left to right, or is docile and obedient preface from right to left, depends on the circumstances.

As for letter on keyboard, if during according to series arrangement, should be transversely arranged or vertical arrangement on earth, or should adopt overall unified version of assigning on earth, or branch coils the version of half shell type, and it is unimportant, as long as the keyboard version of discharging, when handling information, can obtain correct and meet expected result, then all should list consideration in, and assess its every good and bad point.

The theory of invention one-handed keyboard comes from " one hand just can be done, and does not have the necessity that non-with the hands do ".With current working environment, in order to increase work efficiency, the keyboard user often need do different work simultaneously, comprises

1. mat operation keyboard is by inquiry data in the computer.

2. call back and remember summary.

3. simultaneously on the table or search required file or the like in the file cabinet.

This working method has become the routine of present work.Thereby be necessary to consider to design a kind of easy-to-use, meet the one-handed keyboard of ergonomics principle and excellent in efficiency.One-handed keyboard still can be saved the area that takies on the table.The shared on the table area of one tool one-handed keyboard may only be 1/4～1/3 of a traditional type keyboard.

Numerical key group's apportionment exercise (description of numerical key arrangement):

Numerical key is arranged in keyboard top traditionally, forms a line in regular turn, and perhaps right-hand at keyboard is provided with numeric keypad (ten key pattern).But when each finger is placed on the home key, do not touch the numerical key of its top line very easily, need sometimes whole hand shifted near this place, so that the operand keyboard.

In the little finger of toe of the present invention field, may be partitioned into six key positions, is the ideal position of putting numerical key.0,1,2,3,4 are assigned in the little finger of toe field of left-hand side, are risen according to anticlockwise by home key and arrange.5,6,7,8,9 are assigned in the dexter little finger of toe field, are risen by home key, are docile and obedient the direction of clock and arrange bottom, little finger of toe field Shang Yuyi key, the suitable computer function key (Fn) of counting into.When this function key (Fn) and other numerical key co-operatings, can start the function (for example Fn1, Fn2, Fn3 or the like) of the numerical code function key on the similar keyboard in the computer.When this function key (Fn) and other text button co-operatings.Can start the function (for example Fn help, Fn search, Fn delete etc.) of the literal code function key of computer.The present invention wishes as far as possible the function of computation is located on the software, and is very necessary to replace on the keyboard many nothings, and occupies the function key of the hardware formula of many keyboard positions.

In the thumb field, the arrangement of key position (description of key arrangement within a thumbdomain): as what mentioned in the aforesaid discussion of respectively pointing the field that coexists, the thumb field like the sector region of 1/4 area of a circle, is the quite big zone that the thumb finger tip can scan quite.Arrangement in this regional internal key position should be complied with the mode of thumb activity.Therefore, the shape of key and line mode, should be docile and obedient the camber line arrangement that the thumb sideway movement is streaked, just can meet the requirement of ergonomics, the key of controlling with thumb, should be with the linearly line of type of horizontal direction (, then not being the key of a strip arranging according to horizontal direction) as carry key on the conventional keyboard (space bar), also should not vertical rectangular.

Because thumb is strong and flexible, and can scan sizable a slice field, the present invention is kind to use these advantages, and makes every effort to develop the potential of its operated tool.Thereby design in two kinds of thumb fields the mode of keys arrangement

1. thumb arc key group: two row or the multiple row arc keys of controlling by thumb.

2. thumb circular row key group: a group is controlled by thumb, round the circular row key of vernier control device.

Thumb arc key group's summary (description of a thumb-curved key cluster):

1. in the position that belongs to the thumb home key originally, change and be made as the vernier control device, for the thumb finger tip is parked part.Surrounded by four arc keys outside it.

2. with the sideway movement of thumb when slightly crooked, the curve of being painted by the vernier control device during its finger tip scanning is referred to as one's own department or unit curve (curved thumb ' s home line) of thumb as benchmark.This curve is in the thumb field, the boundary of upper strata key row and middle level key row.Lower floor's key row then are in close proximity to the below of middle level key row.

3. carry key (space key) is located at that key row in middle level are being close to the vernier control device but orientation outside hand.For the mode of the activity that cooperates the thumb nature, all curved arrangement of all keys in the field.

4. the switch key of a left side/right hand branch dish (when even the user is with single-hand operated keyboard, the conversion between the first-hand keyboard version of this key control and the second-hand's keyboard version) is located at middle level key row, is being close to the vernier control device but orientation in hand.When the operation sheet hand keyboard, the switching between the first-hand keyboard version of this key control and the second-hand's keyboard version.

5. go up/following lattice font switch key (shift case key) is located at the top of a left side/right hand branch dish version switch key.If when pressing this two key simultaneously, one-handed keyboard can be converted to the last lattice font of second-hand's keyboard version by lattice font under the first-hand keyboard version with thumb.

Thumb circular row key group's summary (description of a thumb circular-array key cluster):

One group of key of being controlled by thumb is arranged in the form of a ring around the vernier control device.Thumb is parked on the vernier control device, can touch easily to be looped around its circular row key on every side, and must painstakingly thumb not moved apart the vernier control device earlier, right Hou button.Control on the pad when palm is parked in, thumb is parked on the vernier control device, and little finger of toe is parked on its home key, and the operation meeting of touching is more smooth and accurate, and the sense of fatigue of hand and wrist can thereby reduce.

Detailed Description Of The Invention (Description of Preferred Embodiment)

Fig. 1 is a top view, shows a pair of palm facies palmaris down, settles on desktop or the keyboard with the most natural posture, draws a virtual body center line (body centerline) outward by user's 6 health front mediads.The left hand 1 and the right hand 2 also respectively have a virtual hand center line 4,5.When both hands 1,2 are flat naturally when stretching, formed angle A 1, A2 are about between 25 degree spend to 35 between hand center line 4,5 and the body center line.Among this figure, the left hand palm indicates it with P1, and the right hand palm indicates with P2, and finger then is marked as F1～F10 in regular turn by left hand to the right hand.

Fig. 2 is left hand 1 profile of depicting, and how to form in order to separate the field that respectively refers in loosening one's grip.The division that each points the field is when leaving standstill with palm, and under each finger activity, the area that can contain decides.

F11, F21, F31, F41 and F51 mark each finger at the flat naturally profile of being retouched out when stretching, area in this contour area, the field, one's own department or unit (home domains) that is decided to be this finger, right Hou, each finger outwards is flared under the greatest limit of this finger as far as possible, describe the profile of this finger again, the area in this contour area is decided to be this maximum field that refers to (maximum domain).Equidistant place in the middle of above-mentioned two fields, the profile of this finger of depicting is decided to be the extended field (extended domain) of this finger.Field, one's own department or unit is the most natural zone in this finger scope of activities, the scope that extended field also is easy to touch for this finger tip.But in the scope within the maximum field outside the extended field, both made and to have been touched by this finger tip, but rather distortion and effort.Therefore the present invention assert in the scope with the field, one's own department or unit of each finger and extended field, is considered as settling and is controlled optimal zone, key position by this finger.For example: F11 indicates the field, one's own department or unit of little finger of toe, and F13 indicates the maximum field of little finger of toe, and middle position between the two at this is the extended field F12 of little finger of toe.F41 is the field, one's own department or unit of forefinger, and F43 is the maximum field of forefinger, and F42 is the extended field of forefinger.F51 is the field, one's own department or unit of thumb, and F53 is the maximum field of thumb, and F52 is the extended field of thumb.

Being arranged on the key position in the field, one's own department or unit, is to conform with the ergonomics principle most.Being arranged on the key position between field, one's own department or unit and the extended field, then is the selection of suboptimum.The key position has both made finger tip touch if be arranged on outside the extended field.But according to the idea of ergonomics, the very unsuitable key position of putting.

Fig. 3 is the result who studies and judges according to Fig. 2, marks the zone that each finger is fit to settle the key position, and this regional spy is called the field (domain) of this finger.The little finger of toe field is for indicating 7, and nameless field is for being denoted as 9.And its extended field is to indicate 8, and the middle finger field is to indicate 10, and the forefinger field is to indicate 11, and the thumb field is then for indicating 12.

Fig. 4 draws the left hand palm, and facies palmaris demonstrates the finger center line FCL1 to FCL5 of each finger F 1 to F5 up, respectively refer to uphold freely and flexion in order to explanation, and be to move along the finger center line.Hereat, the key position that each finger is controlled should be along arranging on the finger center line of this finger, to comply with the mode of this finger activity.

Fig. 5 draws the left hand palm, and facies palmaris and is drawn each position, dactylus place up, to show respectively the uneven in length relative length that reaches each other of finger.Generally speaking:

1 little finger of toe F1 is approximately than the short dactylus of nameless F2.

2. nameless F2 is approximately than short 1/3 to 1/4 dactylus of middle finger.

3. middle finger F3 is the longest, approximately is positioned at palm center line 4 positions.

4. forefinger F4 is approximately than short 1/2 to 1/3 dactylus of middle finger.

5. thumb F5 is minimum, and its finger tip only reaches the Hou one dactylus central part of forefinger F4 approximately.

Fig. 6 is keyboard user's a left hand, stretches the hand shape of being depicted under the state flat naturally, in order to explain each finger F 1 to F5 home key the position that should be provided with how to select.When the finger center line direction of each finger when it stretches Qu Yundong naturally, slightly be bent under the most quiet and comfortable degree, press finger mark with finger tip.The position of finger mark, promptly in each finger field, meet most home key under the ergonomics principle the position that should be provided with.

Fig. 7 stamps more finger mark 15 along holding Fig. 6 on each finger wheel exterior feature of the left hand of describing, with determine all the other each keys the position that should distribute, and determine can hold the optimal number of key position in each finger field.

1. for all five fingers (F1-F5), the top of its home key only is fit to set a key position.

2. three of adversary central authorities finger F 2, F3 and F4, the following of its home key can be assigned three key positions.

3. little finger will be lacked a dactylus because of central three fingers, so its home key below only is fit to assign two key positions.

4. the home key of thumb is vernier control device position, can assign two key positions under it.

Because field that thumb is controlled is the quite big sector region of an area, can set a key position on its home key so the front is mentioned, in fact be meant row (row) key position, i.e. one deck key position.In like manner, in fact two key positions of its home key below are meant that it represents two row key positions, i.e. two layers of key position.All the other each fingers are if inference in like manner more than a file person, is also complied with in the field of being controlled.Every finger between the adjoining finger mark, is drawn strigula SHL more, as the boundary line between two adjacent finger marks, therefore produces many blockages, and these blockages are exactly the position that the key position is set.

Because every finger, under state of nature, stretch or flex is that finger center line along this finger is a benchmark, shown in figure four, so should build up upright bar shape (just folding formula) during the key position file under every finger; And should be to present keyboard on the market, during its file, the arrangement mode of each key but is right oblique formula straggly (promptly tiltedly folded towards the lower right).

Fig. 8 is along holding Fig. 7 but dispense the part of finger mark, and will couple together with each strigula SHL that refers to corresponding height, depicts level and smooth and continuous horizontal curve CHL as along each line tendency again.So form a keyboard, the shape on each key four limit is surrounded by straight line of indulging away and the horizontal curve of walking in it.The process of this design, the arrangement of all keys is regularization on the keyboard in order that make, and has the relation of clear and definite row (column) C1-C10 and row (row) R1-R8.Above-mentioned according to the designed keyboard that goes out of ergonomics principle, the shape of key, generally speaking, the right and left is linearly, up and down the curved shape in two ends; The trend of all curves, middle finger left side person, square neck is oblique to left down.Middle finger the right person, tilt to the lower right.In like manner, the key in the thumb field is a benchmark with the vertical cabling of the middle branch in (virtual) thumb field, the two ends up and down of its each key of left, and below embowment slightly left, two ends are then to the lower right embowment about its right-hand each key.But by the another kind of keyboard that the present invention derived, have the key (circular arraykeys) of annular arrangement in its thumb field, the shape of this circular row key, with aforesaid key shape, then different its interest.

Fig. 9 shows the position in left hand 1 palm key field 17.P-P indicates the horizontal center line in palm key field.Finger and palm part are beaten finger mark simultaneously and are kept the seal and draw dactylus in this figure, use indicating each finger field and slapping the two relative position, key field.

Figure 10 shows three palm keys 21,22,23.This three palms key is that palm key field 17 is divided into three 18,19,20 and set the key position for.

Figure 11 is that palm key shown in Figure 10 is along the transversal formed side view of dotted line P-P.The top that dotted line T-T then shows all palm keys is in order to cooperate recessed with its corresponding hand, and protrudes formed radian.The name of palm key 21-23 is then according to this key corresponding finger in top and fixed.Hereat, indicate 21 and be called little finger of toe palm key Pp, indicate 22 and be called middle fingers and palms key Pm-r, indicate 23 and be called forefinger palm key Pi.

But this type of palm key mat software is designed to the program key of switching regulator with it.For example, but little finger of toe palm key 21 mat software programs are set the on ﹠ off switch of vernier control device (cursor controller) for, in order to the unlatching of vernier control device in the control thumb field or close.

Figure 12 sets forth the mode of operation of palm key, represents it with a, b, c, d, e, f, eight kinds of components of g:

The a component is similar to FIG. 10, shows row's palm key 21,22,23.But the mat software instruction is controlled.(be this triple bond when not touched, or three palm keys all in off position down) this kind control mode is referred to as former formula M0 (original mode) when not in use.In this triple bond, the mode of operation that only has a key to be touched (or being referred to as to trigger) (promptly in three palm keys, only open a key, two keys keep closed condition in addition) has three kinds, is decided to be M1, M2 and M3 respectively, and b shows as component.In three palm keys, if the be triggered mode of operation of (promptly two opening a pass) of two palm keys is arranged, have three kinds, promptly M5, M6 and M7 show as c, d, all components of e.This mode of operation can be considered three kinds " two bondings do exercises prosecutor formula " the collaborative key formula of two keys (or be referred to as).The mode of operation that all is triggered when three palm keys has this mode of operation of a kind of M7, can be considered " triple bond cooperation mode of operation ".

When any two or more keys, cooperation is operated and can be imported an instruction, and then these keys can be called the cooperation key formula of reaching a certain instruction mutually.Cooperation key formula also can be referred to as " conjoint tendon formula ".

The control mode of cooperation key (co-operative keys) can be synchronous mode cooperation key formula (synchronous co-operative keys) or sequential cooperation key formula (sequential co-operative keys).Synchronous mode cooperation key formula means each key that participates in cooperation and is triggered together, in fact, is that each key that participates in a certain instruction must not trigger according to specific order.Sequential cooperation key formula then means each key that participates in cooperation, must trigger in regular turn according to specific order, just can reach the effect that sets.

Figure 13 places the top view of controlling on the pad 24 for left hand.Controlling pad has the comparatively quiet and comfortable support function of just palm concurrently and assist palm and function that finger is located on keyboard.

Figure 14 is the side view of Figure 13 along dotted line A-A vertical profile.Demonstrate left hand 1, control the relevant position between pad 24 and palm key 22 threes.

Figure 15 is the top view of control pad, and indicates slitter line A-A and traverse B-B thereon.Control pad 24 front end central authorities have predetermination and slap protruding 27 (front center guide mount), the Hou end has wide wrist slope 28 (rear-end wristclearance slope), a left side is along having protruding 29 (the left-side palm contour) of Zuo Dingzhang, edge, a left side has protruding 30 (the right-side palm contour) of You Dingzhang, and is furnished with the pad of control positioning spiral shell button 31 (joypad position adjustmentscrew).The predetermination palm is protruding prevents that palm is positioned over when controlling pad, too forward; It has the massage centre of the palm simultaneously concurrently and assists palm comparatively to serve as a contrast placing of subsides and control on the pad.Control the wide wrist slope 28 of pad 24 Hous end, its design shape be to control pad Hou side and the corresponding position of wrist, and squint and descending is to clean up user's wrist space all around, in case the wrist position is oppressed because of touching hamper.The wrist position is wrist tunnel (carpal tunnel) institute through way, and the structure on its anatomy is muscle nerve and blood vessel etc. enters passage between palm and the finger by forearm.Be that research is with the most important anatomic construction in hand operation utensil aspect on the ergonomics, the constriction that the mitigation wrist is born helps the generation of prevention or mitigation Carpel Tunnel Syndrome (carpal tunnel syndrome).And often use QWERTY formula keyboard person, often suffer from this slight illness easily.A left side is slapped protruding and the right side surely and is slapped surely and protrudingly help to make palm to be stable to control on the pad.

Control pad and also can combine, or combine with full wafer thumb field with palm key; Can control synchronously and not disturb mutually.

Figure 16 is for controlling pad 24 side views along dotted line B-B direction transverse section.Show that a left side slaps protruding 29 surely and slap protrudingly in controlling the flange of pad the right and left surely with right, have and assist palm to be positioned to control function on the pad.

Figure 17 is for controlling pad 24 side views along dotted line A-A direction longitudinal profile.Demonstrate the wide wrist slope of deciding the protruding and Hou end of the palm of its front end.

Handle traditional type and shake when defending, must hold rocking bar with whole, thereby limited the work that this hand can't be carried out sundry item simultaneously.

Controlling the essential structure of pad, is that the upper end with rocking bar replaces it with palm protector pad (palm support pad).The mode of the push-and-pull of then following metacarpus position during use replaces the activity in the mode of shaking of holding rocking bar.Therefore can transcribe out metacarpus, positions such as finger and finger tip can be controlled other equipment simultaneously.For example, with the finger tip typewriting, above metacarpus is controlled palm key, and controls vernier control device etc. with thumb.

Figure 18 indicates the control pad and have the X-X of rocking bar (not giving out) and the function of Y-Y direction activity concurrently, and the rotary inductive device is along the function of C-C direction rotation for controlling the top view that fills up.Have the control pad of this two functions Hou concurrently, but the auxiliary keyboard user is satisfactory more smoothly and accurate when typewriting.

Figure 19,20 and 21 Figure 20 show the original position (home position) when controlling pad leaves standstill.Control and to make easy to do upper strata key row (upper row) (a row or multi-row) key position above more of touching of finger before pad can following metacarpus position pushes it against, be called overseas key (power-reach keys) R6 and R10, as shown in figure 19.Control pad and can also descend the metacarpus position that it is dragged to Hou side, make the easy to do lower floor's key that can touch of finger be listed as (Lower row) R4 and bottom key row (bottom row) R5, as shown in figure 21.

Overseas (power-reach) of this paper what is called means the key position that is located at outside each finger field, as the Zhu Jianwei of R6, and the Zhu Jianwei of R10.Therefore metacarpus is evaded the power-assisted of control dish under must mat, makes finger tip can touch the overseas key position of each finger easily, smoothly, rapidly and accurately.

The base portion of rocking bar.Can install rotary inductive device 33 (circular motion sensor), rocking bar itself only is the instrument according to X-axis or Y direction activity, (for example, shakes earlier to the left front according to shaking continuously of the two associativity of doing comprising any, shake Hou side left again, or the like).Rocking bar itself is not had a function of rotary moveable, but the wrist of hand can be done 50 ° rotation activity.According to this fact, the rotary inductive device can be attached to the base portion of remote control rod, the function that rocking bar is had concurrently shake and rotate, thereby handle this keyboard can be more smoothly, and is satisfactory and handy.

The palm key of last metacarpus can be provided with respectively with the control pad of following metacarpus, also can combine and synchronous operation.In like manner, the thumb field of full wafer also can lump together and synchronous operation with the control padding.

The rotary inductive device is incorporated into the keyboard of controlling pad Hou, when playing computer game, can be active more, lively and stimulate.

Figure 22 is an example with left-hand side keyboard (being left hand branch dish), introduces all the feature of the present invention aspect ergonomic designs.

1. this keyboard system is according to the rule of having of designing of the ergonomics principle row (columns) that clearly planning comes out with row (rows).Wherein respectively be listed as R1-R10, because want and can cooperate with the length of each finger, and transverse curvature is lined up arc.Wherein all capable C1-C10 respectively point the bent manner of stretching of nature in order to comply with, and vertically are erected into cylinder, constitute the field (finger domains) of each finger on the keyboard, as shown in Figure 8.C1 and C2 belong to the little finger of toe field, and C3 belongs to nameless field, and C4 belongs to the middle finger field, and C5 and C6 belong to the forefinger field, and C7 to C10 belongs to the thumb field.A key position of thumb and forefinger two field overlappings (being R5, R7, C6 and C7 confluce) is incorporated the thumb field into.Central authorities three refer to the horizontal row of lining up according to arc, be divided into upper strata R1 (upper row, or be referred to as upper strata key row), this layer R2 (home row, or be referred to as this layer key row), middle level R3 (middle row, or be referred to as middle level key row), the R4 of lower floor (Lower row, or be referred to as lower floor key row), bottom R5 (bottom row, or be referred to as bottom key row) and outer R6 (power-reach row, or be referred to as overseas layer key row).Outer key position can be one or more layers.

In the little finger of toe field, laterally the curved key layer of lining up then has upper strata R3, this layer R4, the R5 of lower floor, bottom (being the Fn key) and overseas layer R2.In the thumb field, laterally the curved key layer of lining up then has upper strata R7, middle level R8, and R9 of lower floor and overseas layer R10, the vernier control device is positioned on the camber line of thumb one's own department or unit, is equivalent to a key that is provided with in addition.Two adjacent fields may have overlapping part.Fall within the key position in this zone, can arbitrarily incorporate arbitrary field into according to user's hobby.For example, (being R5C6) and confluce, thumb field (being R7C7) promptly have a key position in the forefinger field, owing to being controlled than being controlled by forefinger easily by thumb this key position, usually with this key position appropriation thumb field.

2. a thumb field 35 (thumb domain) is in it and be equipped with vernier control device 16 (cursorcontroller), because the area that is streaked during the thumb sideway movement is curved, so also curved when thumb field 35 interior each key are transversely arranged.The position of vernier control device 16 then is set on one's own department or unit camber line of thumb (finger tip), is surrounded by four adjacent key positions outside it.The mode that arrange 35 internal key positions, thumb field that another kind is derived, be the colyliform circular row around the vernier control device can be referring to shown in Figure 23 and explain orally.

3. there are three palm keys 21,22,23 in row's palm key field 17 in it, can create eight kinds of key formulas (functionalmodes) M0 to M7, as shown in figure 12.On ﹠ off switch 21 comprising a control vernier control device 16.

4. one by palm pad 24 (palm support pad), and rocking bar (joystick does not provide) and rotary inductive device (circularmotion sensor does not provide) three integrate the control pad (joypad) 24 that forms.The part of palm pad also is equipped with the positioning spiral shell button 36 that can adjust the palm position.

Do masterplate (template) according to this keyboard, mark can be assigned thereon.

Figure 23 shows the keyboard (being left hand branch dish) of a left-hand side, it is that annular eight the key 38-45 of a circle are round vernier control device 16 that its thumb field has circular row key group 37 (circulararray keys), the advantage person of being to use of this design can be with the thumbtip that places on the vernier control device, slide to arbitrary circular row key that institute's desire triggers, and needn't be by on the vernier control device, lift thumb, go again by want by key.

Figure 24,25 Figure 24 are the planimetric map of top view, show the circular row key 37 of a corral outside vernier control device 16, and Figure 25 retouches and provides three circular row keys 39,40,41 after the amplification.Its end towards the center of circle slightly is tip-shape PE, enlarging the distance of the keyway WG between adjacent two keys, and the adjacent key of false touch when avoiding operating.

Figure 26 is a circular row key shown in Figure 24 side view along dotted line W-W direction transverse section, demonstrates two circular row keys 38,42 of vernier control device 16 and foreign side thereof.Sliding action when the user can the thumbtip mat controls the vernier control device triggers its peripheral circular row key, as with the direction shown in the arrow dotted line, and need not comply with traditional key mode, thumb is lifted from the vernier executor, press again want by circular row key 38,42.

Each key preferentially uses being ranked of order on Figure 27 display keyboard.Each key position on the keyboard, according to the complexity of button, and the efficient of typewriting is come rating.The easiest being touched and key position that writing efficiency is the highest is assessed as the key position #1 of the first estate, and inferior being touched easily and writing efficiency time high key position is assessed as the key position #2 of second grade, and the rest may be inferred by analogy.Being ranked of priority ranking used in the key position, is to be used as the foundation of assigning letter or symbol.So a class mark (characters) of the most normal use can be assigned to () high (uses) interior key positions, (rate) district 48,49 frequently.Generally speaking, letter or phonetic symbol often are regarded as the most normal mark that uses, so preferentially be assigned in the high frequency region.In fact, optimal mark method of distribution is needs and the hobby according to use itself, and can decide the sort of mark group in its sole discretion should be assigned in the high frequency region.The number of high frequency of utilization mark group quantity is often different because of the category of language that the user adopted, and for example English has 26 letters, and national language then has 37 phonetic symbols, adds the four tones of standard Chinese pronunciation, thereby can have influence on the size and the face shaping of high frequency region area.Therefore, be necessary to set up out a cover (comprising high frequency region) key position and assign priority principle.Being ranked of key position priority ranking is complexity and the factor of (keyboard and key position) symmetry for mainly worrying according to button.According to priority principle, divide the home key and the zone on every side thereof of a pair of keyboard 46,47 into high frequency region 48,49.Home key (home keys) then is regarded as prepreerence key position, and the middle level key row (keys in the middlerow) of its below then are regarded as time preferential key position.The upper strata key row (keys in the upper row) of its top are then for being considered as the 3rd preferential key position or the like.Number in the figure on each key position then is the priority ranking of each key that the present invention is ranked.At present general QWERTY formula keyboard, because all home keys are linear lines,, make finger tip be the key position of a straight line with the line of cooperation linear pattern so both hands, finger must be done significantly crookedly when using, therefore, its upper strata key row can be regarded as the second preferential key position usually; The home key of this keyboard then is to let nature take its course slightly crooked and set according to each finger, is regarded as the second preferential key position so the middle level key below home key is listed as.

Above-mentioned priority ranking determines this to select that key position earlier for use.

According to the above, bring up one " classification subregion " mark assignment strategy (group-block) principle that is ranked.Institute's markedness (comprising figure of literal, numeral, punctuate, symbol and Presentation Function or the like) is classified according to functions of use, and each class mark is assigned in the zone of special delimitation on the keyboard.The arrangement of such mark in this zone is as far as possible according to certain special order of setting, in the hope of regularization.

The mark assignment strategy of this classification subregion can be taken into account writing efficiency and the easy needs that use two aspects.From the efficient of typewriting, because, be located on the easiest keypad that touches of finger (being high frequency region), so touching is soon and the efficient height when typewriting with the most frequently used mark group (as English alphabet).

From the difficulty or ease aspect of using because the mark in each keypad be docile and obedient preface arrange (as according to alphabetical order, numerical order etc.).The key position of various marks is remembered easily on the keyboard, so use easily.

An other benefit of complying with the mark assignment strategy of classification subregion is to simplify " check and balance " that mark is assigned, and makes the design of check and balance and carries out more or less freely.The check and balance that so-called mark is assigned, the most plain explanation is exactly: control the operating key of certain keypad version conversion, preferably avoid being located within the controlled keypad itself, to avoid causing conflict or to increase complicacy when designing.

Ergonomics and mark method of distribution are two big subjects under discussion of keyboard Designing.Because the shape and the mode of motion of palm are constant.So design the keyboard that closes the hand ergonomic shape, be not difficult, and be easier to guarantee that these principles are prolongedly can not change according to the shape and the mode of motion of palm.But computer function makes rapid progress, and is to be subjected to software control.And the design of software is not only changed easily and it is restricted to be difficult for, so can expect operating key on the following computer, the switch key of various keypad versions and the function key that goes out with software design constantly occur and increasingly sophisticated renovation.Because the computer function developing tendency in future can't expect, therefore to formulate comparatively suitable and grow energy mark assignment principle difficulty of a specified duration very big.Therefore pre-establish more regular classification subregion mark method of distribution and cook up the check and balance that mark is assigned in advance on the key position, be necessary in fact.

Because the mark assignment is one of two big serious subjects under discussion of keyboard Designing, not only the classical literature that can consult is a lot of, also will consider simultaneously and reserves enough leeway can for future development trend, so specially book is on the other for assignment of comparatively detailed mark and check and balance.

Chat the principle that is according to the classification subregion down, assign the example of mark to the key position:

The alphabetic class mark is assigned to high frequency region 48,49

The numeric class mark is assigned to little finger of toe field district 50,51

Punctuate class mark is assigned to the low layer district 52 of left-hand side keyboard 46, or is referred to as the punctuate district,

The symbol class mark is assigned to the low layer district 53 of right-hand side keyboard 47, or is referred to as the sign field,

Literal commonly used or information are handled mark, then are assigned to thumb field 54,55,

Computer function mark commonly used then is assigned to overseas district 56,57,58,59,

Mark with program key of switching function then is assigned to palm key field 60,61.

Figure 28 draws a pair of keyboard 62 and interior two high frequency regions 63,64 thereof, show the arrangement mode of English alphabet in this two district, promptly unified totally formula is laterally crossed over the continuous method of distribution (Continuous horizontalarrangement acrossthe keyboard) that divides dish in regular turn.

Letter is transversely arranged in regular turn, be set at the A keyboard from R1C3 key position, the key position that laterally is aligned to R1C6 in regular turn is set at the D keyboard, and right Hou strides across left hand branch dish 62, and continuation are set at E key to R1C18 key position by R1C15 key position and are set at the H key in the high frequency region 64 of right hand branch dish.The rest may be inferred by analogy.

Figure 29 draws a pair of keyboard 65, demonstrates high frequency region 66,67 interior letters and overlaps horizontally-arranged in regular turn with a minute dish branch.Be about to a cover letter and be divided into two and half covers, preceding half cover is assigned on the left hand branch dish for A-L and Y, and Hou half cover is assigned to right hand branch dish for M-X and Z.A is assigned in the high frequency region 66 of left hand branch dish to L and Y, and the key position that is set in R1C6 by the A word begins letter in regular turn laterally by left and right, and the L letter that drains into R6C6 key position from top to bottom.In like manner, the letter of Hou half cover is assigned in the high frequency region 67 of right hand branch dish, and the key position that is set in R1C15 by the M word begins, and letter is laterally right by a left side in regular turn, and the X letter that drains into R3C18 key position from top to bottom.The Y word is assigned on the extended field R1C2 key position of the left hand third finger; The Z word is assigned on the extended field R1C19 key position of right ring finger.

Figure 30 draws a pair of keyboard 68, and demonstrates left hand branch dish high frequency region 69 and right hand branch dish high frequency region 70.English alphabet is from top to bottom vertical row in high frequency region, from the A word of R1C3 key position, drains into the C word of R3C3 key position from top to bottom, more in regular turn from left to right through vertical arrangement of C4, C5, C6, C15, C16, C17.The mode of the vertical setting of types in regular turn of this English alphabet makes vowel letter A, and E, I divide in the dish leftward, be diagonal line and arrange, and O and U comes with in one deck in right hand branch dish, a therebetween R word.And R is the consonant of the 3rd high frequency of utilization.

Vertical in regular turn row's method of this English alphabet, every finger only is responsible for the operation of three letters of a stringer.Should be responsible for operation by that root finger for cognitive that letter, very convenient, therefore the most easily learn easily note.

Figure 31 draws a pair of keyboard 71, is made up of left hand branch dish 72 and 73 on right hand branch dish, and the mandarin note phonemic notation of preceding half cover is vertical to come in the right hand branch dish 73, and Hou overlaps partly that the mandarin note phonemic notation is vertical to come in the left hand branch dish 72.

Chinese characters and phonetic symbol, generally by the right and straight book formula in a left side, an example provided herein is introduced a kind of method that the mark of straight book formula is arranged in regular turn on keyboard.

National language phonetic symbol (37) is more than the number of English alphabet (26).Simultaneously also be divided into many syllables according to the difference of articulation type, the number of each syllable also is not quite similar, so the shared high frequency region area of national language phonetic symbol is bigger, and shape is comparatively irregular.

Figure 32 draws a pair of keyboard 74, and interior two little finger of toe fields 75,76.It is according to described by figure two to figure eight that little finger of toe field 75,76 profiles are irregular pentagon, and research little finger of toe ergonomic designs principle is resulting result produce.Each little finger of toe field may be partitioned into six key positions, lines up two row (be the C1 and the C2 of left hand branch dish, reach the C19 and the C20 of right hand branch dish) and four horizontal row (being R3-R5 and Fn key) longitudinally.In the present invention, the key position in two little finger of toe fields 75,76 is divided and is tasked numeric character (0-9), and two function key Fn, and one piece of function key is assigned on every limit.

According to ergonomics and writing efficiency, little finger of toe refer to short than three of hand central authorities and a little less than because these consider, so the assignment of mark that can frequency of utilization is not too high is in two little finger of toe fields.

Generally speaking, numeral is than the alphabetical usefulness of lacking, so be assigned to left-hand side 75 with 0,1,2,3,4, is set on the home key R4C2 in left hand little finger of toe field 0, arranges in regular turn with anticlockwise.5,6,7,8,9 be assigned to right-hand side 76, be set on the home key R4C19 in right hand little finger of toe field 5, to arrange in regular turn clockwise.Each little finger of toe field is the key of below, stays and is computer function key Fn, and this function key then can be carried out default function if close use with other bonds.When pressing function key, press numerical key again, then can carry out default numerical code function command, (as Fn1, Fn2, Fn3 etc.).If numerical key and function key be all on same branch dish on hand, can also little finger of toe according to function key, key in digital simultaneously with the third finger.In like manner, if press numerical key with little finger of toe, go by text button with other fingers, then computer can be carried out default literal order (as Fn help, Fn search, Fn delete or the like) again.

When a computer instruction, in the time of can reaching with multiple different mode of operation, key entry literal order (as Fn help) may seemingly not keyed in digital command (as Fn1), and that is simply rapid.But the former is easier to association and uses, but user's mat more the mode of thinking of human nature handle computer, and do not need to remember or understand the function that various numerical function key private mark Hou faces are hidden or the program principle of its execution command.

The design of conventional keyboard is the top that numerical key is placed on Wen Jian, lines up a line in regular turn, or right-hand in keyboard in addition, sets up a keypad based on 10 numeric keys.The numerical key of line above text button, a little far away slightly from each home key that refers to, therefore need sometimes whole hand is lifted, want the numerical key that touches so that shift near.In addition, the keyboard of the present traditional type that circulates, there is a line numerical function key (being F1～F12 etc.) the top.Wherein the function of many keys is heavily covered.These keys take key position a lot of on the keyboard, and carrying out of task is quite limited.It is examples clearly that same keyboard is provided with two cover numerical keys.And long row's numerical function key occupies on the keyboard more than 12 key positions at least, is another example, and the software function that many keys can be preset in fact replaces it.In the present invention, though the key total order in the little finger of toe field is limited, can then can bring into play the instruction of unlimited function key via the assistance of software program.

Figure 33 demonstrates two low layer keypads (Lower blocks) 78,79 that refer to of a pair of keyboard 77.The low key position that refers in the layer keypad of left hand branch dish is divided and is tasked the punctuate mark, and the low key position that refers in the layer keypad of right hand branch dish is divided and tasked the symbol mark.The mark of this two class, the first Hou order of generally acknowledging can be for not doing the foundation of assigning the key position, and therefore, the arrangement principle of mark is considering based on easy-to-use degree and writing efficiency two aspects.

For the purpose of making the easy memory of the keyboard space of a whole page, the mark with following feature, adjacent comes together:

A) be made into right mark: as (with), with, [with],＜with, etc.

B) token shapes is close or symmetrical: as with/, ' with ': and with; ,-with _ etc.

C) mark of similar or correlation function: as $ and ﹠amp; ,? with! , # and % etc.

For the efficient that makes typewriting improves, mark commonly used preferentially is assigned in lower floor's key row, on the key that finger more easily touches.Usually, the key in lower floor's key row is operated easily than the key in the bottom key row.

Carry key (Space Key) R8C9 branch is tasked by the adjacent key position of (being the vernier control device) the easiest of touching, zone, thumb one's own department or unit.Two punctuates of normal use, comma () R7C7 and fullstop (.) R8C7 then divides and task in the left hand thumb field near (the contiguous low digital district) two key positions of more easily touching.

Figure 34 shows two thumb fields 81,82 of a pair of keyboard 80, and this forefinger field is the reprint of reflecting mutually in appearance.So only do representative, explain the design effort in thumb field with left hand:

1) in the position at thumb one's own department or unit, vernier control device 16 is set, this position also is the confluce of its outer four thumb button.Vernier control device 16, it is the operation center in thumb field 81, the key of four arcs of its periphery then is last/following lattice font switch key (shift case) R7C8, backspace key (back space) R7C9 carry key (space) R8C9 and a left side/right hand branch dish version switch key (shift hand) R8C8.

2) sideway movement when thumb is slightly crooked, by the vernier control device, a camber line that is drawn is called one's own department or unit curve (curved thumb ' s home Line) 84 of thumb.This camber line is the separatrix of thumb field 81 interior upper strata key row R7 and middle level key row R8.The key row R9 of lower floor in the thumb field 81 is then below the key row R8 of middle level.

When 3) document being handled, four keys of normal use (promptly going up/following lattice font switch key R7C8 backspace key R7C9, carry key R8C9, and a left side/right hand switch key R8C8) are assigned on four keys around the vernier control device.

4) carry key (Space Key) R8C9 is assigned to middle level key row R8, and next-door neighbour's vernier control device is towards the arc key of the foreign side of hand.

5) left side/right hand branch dish version switch key R8C8 (when being single-hand operated keyboard, first-hand keyboard version and second-hand's keyboard version are changed the on ﹠ off switch of use alternately) is positioned at the key of middle level key row R8 in abutting connection with the vernier control device towards hand side.When single-hand operated keyboard, this key can convert the A-X letter on the keyboard version on a singlehanded limit to M-X letter (as Figure 38, shown in 39).

6) on/and following lattice font switch key (shift-case key) R7C8 assigns above a left side/right hand branch dish switch key R8C8, and the usefulness that this two switch key is adjacent is intended to make things convenient for the people of single-hand operated keyboard.When the single-hand operated keyboard person presses this two keys R7C8 and R8C8 simultaneously with same thumb, then the version of keyboard can convert the version of lattice font on the right hand branch dish to by the version of lattice font under the left hand branch dish at once.(consulting Figure 38,39).

Being assigned as of left hand branch dish thumb field mark, R7C8 be on/following lattice font switch key (shift-case key), R8C8 is a left side/right hand branch dish version switch key (shift-hand key), R8C9 is carry key (space key), R7C9 is backspace key (back space key), R7C7 is comma (comma) key (), R8C7 be fullstop (period) key (.), R9C7 is lifting aspect key (jump key), R9C8 is enter key (enter key), R9C9 is return key (returnkey), R7C10 goes up page key (page-up key), and R8C10 is this page key (Home key), and R9C10 is Page Down keys (page-down key).

Comma key (comma key) R7C7 is provided in a side of a key position at the place that overlaps each other in forefinger field and the intersection district, thumb field.This key position is owing to control than controlling easily with forefinger, so incorporate this key position into the thumb field with thumb.Lifting aspect key R9C7 is the key of one piece of programmable, is mainly used in electronic game and three dimensions signal figure.

The function of the computer of execution that two keys can be worked in coordination with.If this two key can be with a finger triggering, this control mode is referred to as singly to refer to the cooperation key formula (single-finger co-operative keys) controlled.With two keys of this key formula (being fingering) operation, then must be adjacent, so that can operate this key formula.For example, if with the left hand thumb reach by bottom left/masterhand's branch dish version switch key R8C8 simultaneously/following lattice font switch key R7C8 then can trigger the keyboard version, convert lattice font on second-hand's version to by lattice font under the first-hand version.If press this page key R8C10 simultaneously and go up page key R7C10 with the left hand thumb, can make vernier move on to the starting point of file.In like manner, if press this page key R8C10 and Page Down keys R9C10 simultaneously, can make vernier move on to the end of file.

The overseas key layer R10 (power-reach row) of outside, thumb field stays the function key of making some computer.As eliminating (delete), insert (insert) selected (select) etc.Selected button preferably sets up separately with anti-white key (high lighting key).As desire data of a certain fragment anti-white (promptly emphasizing) or elimination anti-white (delighlighting) then must be pressed palm key 21 and 22 earlier, right Hou is again with thumb-actuated vernier control device.This mode of operation can be considered the cooperation key formula that a kind of three keys are operated simultaneously.

The hand thumb field, be centered around four key positions outside the vernier control device 83, it is the version of lattice font (Lower case) down, it is that a left side refers to arrow (←) that branch is tasked four sensing arrow (arrow keys): R7C12, R7C13 upward refers to arrow (↑), R8C13 is that the right side refers to arrow (→), and R8C12 refers to arrow (↓) down.The version of the last lattice font (upper case) of this quadruple linkage, divide and to task arithmetic operator number: R7C12 is add key (+), and R8C12 is Substract key (-), and R8C13 is multiply key (*), and R7C13 is devide key (÷), and the mark of all the other key positions is assigned, and is omitted herein.

Figure 35 shows a pair of keyboard 86, includes circular row key group (circular-array keyclusters) 89,90 in the thumb field 87,88.Circular row key group is the key in the thumb field, arranges around vernier control device 16,83 to form.The thumb finger tip can be by on its vernier control device of parking, easy to do its any circular row key on every side that touches.Therefore the user needn't mention thumb painstakingly from the vernier control device, right Hou go again to press want by the circular row key.The key position arrangement mode of this improvement makes the key of controlling in the thumb field, and being more prone to of change is efficient and meet the principle of ergonomics.

Control on the pad when palm is parked in, little finger of toe is parked in its home key R4C2 and R4C12 goes up and thumb is parked on the vernier control device 16,83, and the action of touching will be more smooth, accurately; And can relax the sense of fatigue at positions such as hand, wrist, arm, shoulder.

The assignment of mark on the circular row key group 89 of left-hand side, by left hand thumb one's own department or unit camber line 84 inboard rising, be docile and obedient clockwise and be arranged as: a left side/right hand branch dish version switch key (shift-hand key), comma key (), the fullstop key (.), backspace key (back spacekey), carry key (space key), return key (retumkey), on enter key (enterkey) reaches/following lattice font switch key (shift case key).Two documents commonly used are handled mark, and promptly a left side/right hand branch dish version switch key and carry key is set in left hand thumb one's own department or unit camber line 84 and passes through part.

A left side/right hand branch dish version switch key and last/following lattice font switch key can have the relation of cooperation key formula between the two.If when pressing this two key simultaneously with thumb, then key face version can convert the version that the second-hand goes up the lattice font to by the first-hand version of lattice font down.

The assignment of right-hand side circular row key group 90 marks, rise by hand thumb one's own department or unit camber line 85 is inboard, be arranged as according to anticlockwise: multiply key (*), on refer to arrow key (↑), devide key (÷), a left side refers to arrow key (←), add key (+), following finger arrow key (↓), Substract key (-), reach the right side and refer to two arithmetical operation keys commonly used of arrow key (→), promptly add key and multiply key are set in hand thumb one's own department or unit camber line 85 and pass through part.

Figure 36,37 shows the amphitypy one-handed keyboard, promptly partly overlaps alphabetical version type single-hand operated keyboard 92 and a complete set of alphabetical version type single-hand operated keyboard 93.

Figure 36 is the keyboard 92 of a tool one-handed performance, even slaps key 2l, 22 and 23 and counts, and has 52 key positions.On the keyboard version of this type keyboard 92, can only demonstrate half cover letter (partly overlap letter promptly and also claim first-hand version 94, its font is presented at the lower left corner of each key at every turn; Or Hou half cover letter, also claiming second-hand's version, its font is presented at the upper right side of each key.) partly overlap version or Hou before can only having during each button and partly overlap version and can be triggered.Therefore one a piece of left side/right hand branch dish version switch key 96 (a kind of key of similar switch) must be equipped with, when being used in operation keyboard, the version on the keyboard can be made, between first-hand version 94 and second-hand's version 95, needs during according to operation and constantly changing alternately.

To control English alphabet owing to occupy three fingers (being forefinger, middle finger, the third finger) of hand central authorities, so three refer to any key position in addition, (because can not hamper the key entry of English alphabet), all can list the switch key of considering to be set as a left side/right hand version in, but be good with the key position in thumb field or the palm key field.Because disturb in the time of can avoiding operating with English alphabet.

Figure 37 is a tool one-handed keyboard 93, has 67 key positions, the English alphabet of a complete set can be included in the keyboard.And one piece of left side of unnecessary outfit/right hand version switch key.On this keyboard 93, the area of each key reduction 1/3 can be held more key position so that make on the keyboard, have influence on ergonomics principle and writing efficiency in order to be unlikely, so only the height of key can be shortened 1/3, the width of key then should not reduce.The width of key should keep with each finger (or field) with wide, or each the finger (field) slightly wideer.

The function that a left side/right hand version switch key 99 on the alphabetical version type single-hand operated keyboard 97 is partly overlapped in Figure 38,39 demonstrations.With singlehanded manipulation keyboard the time, the user can be according to each one hobby, optional left hand branch dish 97 or right hand branch dish (not drawing).With the keyboard of one-handed performance, the mode that mark is arranged on the left hand branch dish claims left-hand version 100, and on the keyboard of one-handed performance, left-hand version is called first-hand keyboard version again.The mode that mark is arranged on the right hand branch dish is called right hand version 101, and right version is called second-hand's keyboard version again on the keyboard of one-handed performance.The function of a whole set of keyboard all can be carried out in right-hand man both sides, the branch dish on every limit.

Selected (as English alphabet, national language phonetic symbol etc.) and method of distribution (as line in regular turn or vertical in regular turn row, branch coils half cover type or unified totally a complete set of type) as for mark on the keyboard then can be different according to user's hobby.

When operation is equipped with the single-hand operated keyboard 97 of a left side/right hand version switch key 99, before often being parked in, partly overlaps on the version 100 mark on this one-handed keyboard 97, unless supress a left side/right hand version switch key 99.When supressing a left side/right hand version switch key 99, the version on this one-handed keyboard 97 is then converted to Hou and is partly overlapped version 101 by the preceding version 100 that partly overlaps; But the versions in the thumb field 102 are not limit by this, in thumb the field in the switching of version by slap key field 21,22,23 control (be version operating key not should with by the version of its control, be located in the same field).When unclamping a left side/right hand version switch key, the version of mark on the keyboard, by the version 101 of Hou half cover, the version 100 of half cover before jumping back to automatically.In thumb field 102, switch the first cover version, 103/ second cover version 104 and lattice font/go up lattice font (not drawing) down, then must press two keys outside the thumb field 102.This two key is preferably selected the operation that can not hinder five fingers for use.Control the switching of thumb field 102 key face versions with on-off mode so preferably select palm key 21,22,23 for use.The switch of little finger of toe palm key 21 control vernier control devices 16.In on the fingers and palms key 22 control thumb fields 102/switch key of following lattice font.Forefinger palm key 23 is control 102 left sides, thumb field/right hand space of a whole page switch keys.And the collaborative key formula of middle fingers and palms key 22 and forefinger palm key 23 can make the version conversion in the thumb field become the second last lattice font (referring to C component among the figure 12, the palm key key formula of M4) of overlapping.

When typewriting, often need stamp lattice font (being uppercase).At present the QWERTY formula keyboard that uses must make and with the hands carry out this operation, promptly with the thumb of a hand by live in/during following lattice font switch key, key in uppercase with the another hand simultaneously.When using the present invention partly to overlap the one-handed keyboard 97 of alphabetical version, many switch keys are arranged on the keyboard, but need only carry out the operating process of lattice font with a hand.This is because switch key and the version (as English alphabet) that is switched when a certain task of the collaborative execution of needs, must be considered in different key positions, must divide the different field that is located at.Therefore when carrying out co-operating, can not hinder mutually.For example:

1) unless supresses/following lattice font switch key otherwise version on the keyboard, the following lattice font 100 (being small letters) of half cover letter before often showing.

2) on pressing/during following lattice font switch key 98, preceding on the keyboard partly overlaps alphabetical version, become by lattice font down and go up the lattice font.But the variation of thumb field mark version is not subject to the limits.

3) when by bottom left/right hand version switch key 99, the mark on the keyboard converts lattice font under second-hand's version to by lattice font under the first-hand version.But the variation of thumb field mark version is not subject to the limits.

4) simultaneously by bottom left/right hand version switch key 99 and on/during following lattice font switch key 98, the mark on the keyboard by preceding half cover letter down the lattice font convert Hou half cover letter to and go up the lattice font.But the variation of thumb field mark version is not subject to the limits.

5) press in during fingers and palms key Pm-r22, the mark in thumb field 102 converts the lattice font to by lattice font down.

When 6) pressing forefinger palm key Pi23, the mark in thumb field 102 converts lattice font under the second cover thumb version to by lattice font 103 under the first cover thumb version.

7) press forefinger palm key Pi23 and middle fingers and palms key Pm-r22 simultaneously, the mark in thumb field 102 by the following lattice font 103 of the first cover thumb version, converts the last lattice font (not shown) of the second cover thumb version to.

Figure 40 draws a pair of keyboard 105, the painted rule of each key and mark on the elaboration keyboard, and painted keyboard, but the friendly easy-to-use of keyboard emphasized in assisting of mat vision.

Each key on the keyboard all has multiple characteristics, the position of these features and each key, and function and mode of operation are relevant, and be now that some key character Chen Xu of key is as follows:

1) position (Location): indicate the position at key place on keyboard, i.e. the row (Column) of this key on keyboard and the relation that is listed as (row).On the keyboard of model shown in the present, in respect of 20 row, 10 row.

2) function (Function): indicate the attribute of key on function, for example, letter key, numerical key, punctuation key, symbolic key etc.In fact, can design the function on key, noncountable meter.

3) mode of operation: point out the control method of key, promptly this key is controlled with that position of hand, that is relevant with the field at this key place.This keyboard has seven fields, comprises the control pad field that the metacarpus position is controlled under using.

4) cooperative relationship: point out by those two or more keys to have the collaborative simultaneously function of carrying out a certain task.One piece of vernier control device is arranged, four pieces of switch keys and many other specially designed cooperation key formulas on the branch dish of the every limit of the present invention at present.

5) frequency of utilization: point out the frequency of utilization of a certain mark, as carry (space), comma (), fullstop (.) and five the most frequently used consonant primary and secondaries (being T.N.R.S.H) etc.

For can be distinct and clocklike indicate the various features of each key, the user can be come into plain view to the mode of mark on the keyboard and keyboard layout, the present invention uses the appearance profile (Out Line) of different thicknesses simultaneously, and the painted and different embedded color (Inlays) of different color is put the numerous and jumbled various features of this quantity in order.

Appearance profile (Out Line): appearance profile (for example open letters) can be used to do keypad (blocks), the boundary of key and mark.

1. keypad (blocks): the boundary of difference in functionality keypad, can locate with black at the keyway (key gaps) of two adjacent key, especially the scope at high frequency region place should significantly mark (consulting figure 27 and explanation thereof)

2. key (keys): if necessary, the painted feature of indicating this key that the gabarit of key can also be different, or and other keys between relation.

3. mark (characters): various marks (for example English alphabet) black line that available thickness is different, describe its appearance profile (promptly causing open letters).Selecting the reason of black line for use, is clearly demarcated because of the contrast of its depth, can worry that the user visits colour blindness is not arranged simultaneously.As for the thickness of lines, then give expression to the frequency of utilization of this mark.For example, mark commonly used, used lines on its open letters, relative is also thicker.

Color (colors): seven fields on the keyboard give painted according to seven color order of rainbow.Painted than a little deeply except each home key, the background color of each key makes every effort to light painted under the situation that can recognize its color.The color of home key, identical with the background color in its field, place, but painted slightly dark than other key in the same domain.Key or the mark on it also can have and its inconsistent color in field, place but in some cases.

1) field (Domains) painted: each field of every limit branch dish, assign a kind of rainbow color in regular turn.

Red: as to divide and task little finger of toe field C1-C2, C19-C20;

Orange: as to divide and task nameless field C3, C18;

Yellow: as to divide and task middle finger field C4, C17;

Green: as to assign and give forefinger field C5-C6, C15-C16;

Blue: as to divide and task thumb field C7-C10, C11-C14;

Indigo look: divide the pad field 24,91 of controlling of tasking; And

Purple: divide the palm key field of tasking, be palm key each key 21-23 of field, the gabarit color of 108-110.

2) key (keys) is painted: the backcolor of each key is consistent with its field, place color, and only the painted summary of each home key can comparatively highlight it more deeply, in order to express each finger tip the position that should place.Participate on each key of cooperation key formula (co-operative keys) same hue being arranged, show conspiracy relation therebetween.

3) mark (characters) is painted: unless stated otherwise, the gabarit (being outline letters) of letter is a black.The inside of its outline letters can embed different colors.

4) embedded (inlays) painted: the embedded color of hollow mark (letter), preferably different with the color of its outer background, with the effect of enhancing color contrast.The embedded color of vowel letter (vowels) is red, and the embedded color of consonant letter (consonants) is blue, and the embedded color of numeral (numbers) is green.Do not chat herein and other colors, (for example: white, grey, brown etc.) requires for other purposes.

Now according to the painted principle of above-mentioned mark (characters), provide following several example with key (keys):

Example one, be positioned at R2C18 key position and be:

A. be positioned at nameless field---be orange field.

B. be home key---its orange should be dark.

C. this key position branch is tasked the T letter--and the embedded color of-consonant letter is blue.

D.T is that the consonant primary and secondary of using always--the lines of-alphabetical gabarit are thicker.

Therefore, key on R2C18 and mark are: the key of darkorange, the hollow T word of thick line, embedded blueness.

Example two, be positioned at R3C15 key position and be:

A. be positioned at the field of forefinger field----for green.

B. the absinthe-green key of non-home key----.

C. this key branch is tasked the embedded color of u letter----vowel for red.

D. being positioned at the corner of high frequency region----is black at the keypad keyway adjacent with keypad.

Therefore, be at key and the mark of R3C15: absinthe-green key, the hollow u word of fine rule, embedded redness, the keyway of its left side and below is a black.

Example three, the palm key 21 painted:

A. this key be positioned at the palm key field----be the purple field.

B. be the vernier control device operating key----vernier control device be located on the position, thumb one's own department or unit, so be darker blueness.Therefore, palm key 21 outer colors are lilac field looks, embedded darker blueness, show its with the vernier control device between, certain co-operating relation existence is arranged.Between two kinds of colors, separate with black line.

Example four, palm key 22 are operating keys handling thumb field (be on/following lattice font switching) in thumb the field in, and therefore, the outer rim of key is with lilac field color, and internal color is the light blue thumb field color that is subjected to its control with correspondence.Separate it with black line between two kinds of colors.In like manner, palm key 23 is another operating key (being a left side, thumb field/right version switch key).Therefore, the outer rim of key is a lavender, and embedded color is light blue.Separate it with black line between two kinds of colors.

When two or more keys, has identical embedded color, it then may be a kind of indication, point out these keys each other, have crew-served relation and exist, for example: as the single-hand operated keyboard person, desire to make the version in the thumb field, by lattice version under the first-hand thumb field, when converting on second-hand's thumb field the lattice version to, then must press palm key 22 and 23 simultaneously.

Example three and example four point out that collaborative key preferably has identical embedded color each other, uses the relation that shows therebetween.

Figure 41 introduces several comparatively friendly methods of easily learning of keyboard operation exercise that make:
