Description

The one-handed performance computer keyboard

Technical field:

The utility model relates to a kind of one-handed performance computer keyboard

Background technology:

At present, what widely used computer standard keyboard adopted is the keyboard layout mode of english typewriter, the dictionary why inventor of this keyboard layout upsets English alphabet puts in order, be in order to stop people to improve typing speed, thereby avoid typing speed too fast and machinery typewriter card key phenomenon occurs, this layout has solved card key problem at that time, and has obtained extensively popularizing, but, there has not been the problem of keyboard card key in today.And the first learning keyboard touch system of this layout requirement people, could use faster, and touch system study is wasted time and energy, thereby such layout has not met the requirement that people improve input speed fast.The mode of its bimanualness keyboard also is inconvenient to use mouse or literal extracts to wait other work.The modern household computer develops to miniaturization, microminiaturization, portable direction, can too disperse owing to the layout of present QWERTY keyboard, makes volume and weight excessive, and inconvenience is carried.

Purpose:

The purpose of this utility model provides a kind of work efficiency that can improve the people, is convenient to one-handed performance, portable computer keyboard.

Technical scheme:

Solution of the present utility model is: 69 buttons of whole keyboard sharing, the below is input field totally 40 buttons, the input field is divided into primary input district, inferior input field, compound keypad, and press horizontal 8, vertical 5 rectangle and arrange, it above the input field general function keypad, English alphabet and numeral, symbol (except that fullstop/question mark key) overlap on primary input district and time input field, and three compound keys, Tab, Caps and backspace key, question mark/fullstop key, enter keys are arranged on the compound keypad.English arrangement in the primary input district is that preceding 20 English alphabets are arranged in alphabetical order, 6 remaining English alphabets alphabet sequence in 2 inferior input fields is listed in respectively on the middle three row key positions, numerical key with the former layout type integral transplanting of QWERTY keyboard numeric keypad 0～9 in the primary input district and the arrangement of keeping right, other conventional sign key is listed the master except that numerical key respectively in, on the key position of inferior input field, except numeral/English switch key and the space bar, be positioned at the primary input district keep right three row keys directly over be cursor key, the F function key area is positioned at the top of cursor key, its left side is an esc key, the right side is a status indicator lamp, is other function key about cursor key.

The utility model has increased a numeral/English switch key and status indicator lamp thereof especially in the input field, with its whole English and input state digital, symbol of switching, Num Lock function and pilot lamp thereof have been cancelled, two keys of Shift, Caps have been carried out part adjustment on use and the function, the numeral/when English switch key is in English input state, numeral/English status indicator lamp goes out, and be the english lowercase input state this moment, and this state also is the computer booting default conditions.Identical with standard computer keyboard compound keys use-pattern, under the english lowercase state, add certain English alphabet keys by Caps, then be this alphabetical upper case character; Identical with the mouse use-pattern, double hit Caps twice, then all English alphabets change the capitalization input state into, and this moment, Caps Look pilot lamp was lighted, and double hit Caps is twice again, gets back to computing machine acquiescence small letter state.No matter be under English capitalization or small letter input state, by numeral/English switch key, its pilot lamp all can be lighted, can directly import the numeral or the symbol in all English alphabet upper left corners this moment, under this state, open the counter program, directly input digit and add, subtract, the multiplication and division computing.The utility model is when English alphabet is imported to the change of shift key, the use-pattern and the general function that keep former Shift, but shift key is no longer controlled the capital and small letter of English single letter, and the numeral and the symbol in the single button of the control the utility model keyboard upper left corner, no matter be English capitalization or small letter, press Shift+ ..., be the numeral or the symbol in the button upper left corner, as press Shift+ fullstop key, input be the question mark in the fullstop key upper left corner.

Computer keyboard is as one of input equipment of computing machine, the system controlling software that is controlled by computer-internal, read only memory ROM in the machine on the mainboard is being stored a series of programs and the data that write in advance by computing machine manufacturer, basic input/output software BIOS wherein is the basic support software of keyboard, all signals from keyboard must just be transmitted to host cpu CPU after this software processes, received by CPU and carry out.Keyboard signal is received and carries out by computing machine in other words, must be by " translation " conversion of basic input/output software BIOS.A certain key is pressed, promptly send " scan code " corresponding to this key position to keyboard controller, decontrol this key, send one " disconnecting sign indicating number " again: " scan code " that the keyboard I/O driven element program in the bios software will be received and " disconnecting sign indicating number " convert corresponding " ASCII " sign indicating number to, pass to CPU again; CPU finds out corresponding letter, symbol or corresponding concrete function according to " ASCII " sign indicating number, is presented on the screen by display, or sends command adapted thereto.

According to above system principle, the utility model is by revising or rebuild the keyboard I/O driven element program among the basic input/output software BIOS, make it to the adjustment making to meet above-mentioned letter from " scan code " of keyboard and put in order and the adjustment on indivedual keypress function, and convert corresponding with it " ASCII " sign indicating number to, thereby realize above-mentioned functions for CPU reception, execution.

The utility model has the advantages that: adopt the one-handed performance mode, mainly be thought of as left-handed operation, but the right hand also can be convenient to use, be convenient to do simultaneously other work, English alphabet is arranged the thinking memory habit that meets the people in order, be beneficial to the raising input speed, the overlapping discharging of numerical key and English alphabet, the key position of having strengthened simultaneously when numeral is imported the English alphabet button is familiar with, English input and keyboard input form digital, that the symbol input is mutually promoted have been formed, also significantly reduced the keyboard grabbing space, made keyboard be more convenient for carrying.Homeotropic alignment is up and down totally adopted in the input field, the direction that finger moves when meeting one-handed performance, the primary input district is that four row buttons vertically discharge, made things convenient for the operation of forefinger, middle finger, the third finger, little finger of toe to major key, the size and location of space and enter key combine the ergonomics principle, also made things convenient for the operation of left hand thumb, about complex function keypad apportion input field, meet the established keyboard layout custom of people, cursor key is positioned at top, primary input district, arranged side by side with the primary input district three row buttons of forefinger, middle finger, nameless control, use easily.
