Abstract

A single-hand keyboard suitable for disabled people and non-professionals can be used for computer, typewriter and notebook computer, and features that its double-action switches, key shape and key assignation are different from ordinary keyboard. It has small size decreased by fold.

Description

One-handed keyboard

The one-handed keyboard that the present invention relates to a kind of computing machine, typewriter and can match with notebook computer, this keyboard has double acting switch, key shape and the keyboard arrangement method of the common keyboard of being different from.The computing machine that the particularly a kind of left hand or the right hand can be operated separately, typewriter and the one-handed keyboard that can match with notebook computer.

No matter be computing machine now, or typewriter, and notebook computer, its keyboard is bimanualness.Bimanualness button area occupied is big, and natural keyboard volume is also big, and especially notebook computer for adapting to bimanualness, is difficult to reduced volume again.Simultaneously, the operator must the positive big seat of the flap, can cause certain fatigue to waist, arm for a long time, and because operation posture fixing, environment for use also is restricted, and particularly notebook computer directly has influence on its usable range.

The present invention is intended to by scientifically designing double acting switch, key shape and arrange-key position, and it is compact, rationally that the key position is arranged, not only can one-handed performance, and reduce several buttons and operate phenomenon simultaneously, make the operator without any inadequate or sense of discomfort.And guaranteeing not occur to mix and beats phenomenon, also provide a desirable computer operable keyboard for disabled person and non-computer professional, is the further reduced volume creation of notebook computer certain condition.

With reference to accompanying drawing, button is capable to intersect dislocation with row and is the fish scale shape and arranges, and center fixation refers to keep 19 millimeters normal pitches about a button, guarantees that the operator has good hand feeling, arranges and then equals to press from both sides delegation in the ranks two and intersect dislocation fish scale shape up and down.Button four limits can be circular arc type, equal to have increased the button area, also can be according to the global design of keyboard or use-pattern one such as notebook computer, and button is designed to other arbitrary shape.Key can be step-like form up and down, during promptly by arbitrary key, is unlikely to by to two following keys, or as required, such as notebook computer, can also be designed to film touch form etc.For adapting to the established custom of majority operation person, letter key keeps putting in order of primary standard keyboard, and numerical key and symbolic key then are arranged in the appropriate location according to frequency of utilization.The major function key then is even numbers as required and is arranged in the left-right symmetric position, to adapt to left hand or the right hand is operated separately.For making things convenient for one-handed performance, disabled person particularly, operating key has two moving functions, normally pushes to be the operating key single action, heavily by two key interlocks then.The button of numerical key and some and operating key, shift compounding practice all can adopt two moving functions, omits two and refers to push simultaneously waste time.For looking after vast financial affair personnel, skilled especially small digital keyboard keeps.In a word, whole keyboard is fit to singlehanded input operation fast fully.

This one-handed keyboard is compared with QWERTY keyboard, has following advantage: 1, can left hand or right hand the five fingers location one-handed performance, operation posture without any restriction, is especially cooperated with notebook computer, and can under any environment, operate.2. concentrate because of the key position,, also can reach per minute 70 words, be fit to disabled person or non-computer professional and use even point is beaten.3, operating key and numerical key etc. adopt two moving functions, have reduced the time that three fingers and two assignment closing operations delay.4, keyboard volume dwindles, is convenient for carrying and puts, and especially being fit to needs to match with the equipment of button with notebook computer or other.5, the beginner is easy to grasp, because only must practise five fingers.6, production economical with materials, cut the waste.QWERTY keyboard then must bimanualness, and especially typing basically must the professional, because layman's point is beaten, the key interdigit is too far away apart, and speed is slower.Because of keys such as control must refer to push simultaneously by three fingers or two sometimes, disabled person's operation is difficult especially.Bimanualness requires tight to posture, have sense of discomfort for a long time.Moreover continuing to cooperate difficult with notebook computer, the button area occupied is difficult to dwindle again.

Technical solution of the present invention is as follows:

With reference to accompanying drawing, keyboard keeps primary standard keyboard form on the whole, and the numeric keypad original position is constant, and copies function key such as screen, screen locking and the F1-F12 key places the top jointly.

Letter key places main body keyboard central authorities, and keeps its former putting in order haply, and punctuation mark key and numerical key that frequency of utilization is high together place the letter key top position, positioning key when the G key is left hand or right-hand operated.Refer to the position when finger position of fine rule sign is for right-hand operated on the keyboard, middle finger, the third finger and little finger divide the work to operate two keys on three keys of its upper, middle and lower and next door, totally five letter keys in principle.Consider its sensitivity level, forefinger is then operated ten letter keys, and is in fact truly feasible.As left-handed operation, except that middle finger was constant, other then could in reverse order.Enter key places the origin-location, uses frequent back spacer to place its symmetric position when importing fast.Shift places inferior horn place, the left and right sides, and just in time at the thumb place, two is corresponding for space bar.Operating key CTRl and AIT place the left-right symmetric position, and are two moving forms, promptly normally push the operation into CTRl, heavily by then being the two moving operations of CTRl and AIT.Reduced by a finger presses, to be fit to one-handed performance.Whole key face is arranged and is entirely the convenience that adapts to one-handed performance, comfortable designed, and also lays the foundation for further cooperating with notebook computer.

More than be the one-handed keyboard of standard,, then can be designed to other arbitrary form if match with products such as notebook computer or equipment.

Below be embodiment:

With reference to accompanying drawing, after the start computing machine placed the Chinese character five stroke word pattern input state." Practice is the sole criterion for testing truth in input." right-hand operated: little finger hits the P key, and the third finger hits the U key, hits the K key, and middle finger hits the H key, and screen display " is put into practice " two words; Middle finger continues to hit the J key, and thumb hits space bar, shields on the "Yes" word; Forefinger hits S key, W key, C key, W key, and " check " goes up screen; Forefinger hits the F key, and middle finger hits the H key, " G " key, and the third finger hits the J key, and " truth " goes up screen; Forefinger hits the R key, and thumb hits space bar, " " shield on the word; The third finger hits the K key, and forefinger hits the W key, middle finger double hit G key two times, and " unique " goes up screen; Forefinger hits S key, F key, and the third finger hits the U key, and forefinger hits the W key, and " standard " goes up screen; Middle finger hit "." key "." number last screen, " Practice is the sole criterion for testing truth for screen display.”

Left hand is by referring to that the same operation in position gets final product, and omits here.

This one-handed keyboard is because key position compactness, though single give directions lose into, also can reach input 60 to 70 Chinese character in one minute, be particularly suitable for disabled person or computing machine layman and use.Especially cooperate with notebook computer, pearl connects an ancient piece of jade, round, flat and with a hole in its centre and closes especially, the barrier of benefiting mutually.
