Abstract

A novel high-efficiency computer keyboard comprises a main keyboard area, character keys, function keys and control keys, wherein the character keys arranged at the ten positions of an upper row on the main keyboard area are a 'K' key, a 'Q' key, an 'X' key, a 'G' key, a 'D' key, a 'J' key, an 'M' key, an 'O' key, an 'R' key and an 'L' key respectively from left to right, the character keys arranged at the ten positions of a middle row on the main keyboard area are an 'I' key, a 'W' key, an 'N' key, an 'S' key, an 'E' key, a 'T' key, an 'A' key, a 'Z' key, a 'U' key and an 'H' key respectively from left to right, and the character keys arranged at the ten positions of a lower row on the main keyboard area are a 'P' key, a 'B' key, an 'F' key, a 'V' key, a 'C' key, a 'Y' key, a ',' key, a '.' key, a ';' key and a '/' key respectively from left to right. The novel high-efficiency computer keyboard has the advantages of enabling the loads of the left hand and the right hand to be balanced, enabling the load of the middle row to be large, enabling the sequential alternating frequency of the double hands to be high and enabling the frequency of the same fingers to be low, and the operating speed and comfort level of an existing computer keyboard are obviously improved.

Description

A kind of novel efficient computor-keyboard

Technical field

The present invention relates to a kind of computor-keyboard, particularly a kind of novel efficient computor-keyboard.

Background technology

The keyboard of current use is all qwerty keyboard layout, gains the name with 6, the left side letter of keyboard first row letter.At first, the keyboard of typewriter arranges in alphabetical order, if but typing speed is too fast, the combination of some key is easy to occur card key problem, so ChristopherSholes has invented qwerty keyboard layout, the most frequently used several letters are placed in reverse direction, " under the unlikely prerequisite blocked, improving typing speed " as far as possible.The commercial typewriter of the First of this layout within 1873, is used successfully to put on market.Why Here it is the arrangement mode of keyboard today.But before this 129 years formed, continue into the present in the keyboard arrangement mode slowed down for the purpose of the speed of stroking.Within 1986, Bruce Bai Liwen jazz once represented in " marvellous writes machine " literary composition: " arrangement of QWERTY there very is not efficiency." such as: most of typist's righthanded, but use QWERTY, left hand has but born the work of 57%.Two little fingers of toe and the left third finger are the fingers not having strength most, but again and again will use them.Come the letter of middle row, its utilization rate only accounts for about 30% of whole typewriting task, therefore, in order to make a call to a word, often wants high and low to move finger.Along with the development of technology, the card key problem that keyboard is mentioned before not existing already.Have expert to propose, concerning the typing speed of optimum, keyboard should be designed to:

1), the load of the right hand and left hand should be equal.

2) load of middle row (homerow), is maximized.

3), the frequency of two hand sequence alternates maximizes, and the frequency of identical finger minimizes.

Summary of the invention

The invention provides a kind of high efficiency computor-keyboard, the layout of existing QWERTY computor-keyboard is optimized, under keeping the original function key of qwerty keyboard and the constant situation of operating key layout, optimize the layout of 26, major key panel character keys and 4 punctuation mark keys totally 30 key mappings, improve that existing qwerty keyboard right-hand man is load unbalanced, low, the identical finger of middle row's load knocks the high defect of frequency continuously.When inputting with this high-level efficiency computor-keyboard, there is the low advantage of the frequency of high, the identical finger of frequency of large, the two hand sequence alternates of load of right-hand man's load balancing, middle row, significantly improve operating speed and the comfort level of existing computor-keyboard.

The technical solution adopted in the present invention is:

A kind of novel efficient computor-keyboard, optimizes the layout of 26, qwerty keyboard major key panel character keys and 4 punctuation mark keys totally 30 key mappings.The character keys of upper row 10 location arrangements in major key panel, is respectively from left to right: " K " key, " Q " key, " X " key, " G " key, " D " key, " J " key, " M " key, " O " key, " R " key, " L " key;

In the middle of major key panel, the character keys of 10 location arrangements of row, is respectively: " I " key, " W " key, " N " key, " S " key, " E " key, " T " key, " A " key, " Z " key, " U " key, " H " key from left to right;

The character keys of 10 location arrangements of the lower row in major key panel, is respectively from left to right: " P " key, " B " key, " F " key, " V " key, " C " key, " Y " key, ", " key, ". " key, "; " key, "/" key.

In the middle of during in order to increase typewriting, the load of row, puts 10 character keys by the medial exhaust in major key panel, by existing qwerty keyboard "; " key mapping is also set to character keys.

Consider that people have got used to using existing qwerty keyboard on market, keep original function key and operating key layout constant.

A kind of novel efficient computor-keyboard of the present invention, qwerty keyboard major key panel layout is optimized, and take into full account the situation of English Typing and the typewriting of Chinese spelling, during input, there is the low advantage of the frequency of high, the identical finger of frequency of large, the two hand sequence alternates of load of right-hand man's load balancing, middle row, significantly improve operating speed and the comfort level of existing computor-keyboard.

Accompanying drawing explanation

Fig. 1 is the major key panel layout of computor-keyboard of the present invention.

Embodiment

A kind of novel efficient computor-keyboard, considers that people have got used to using existing qwerty keyboard on market, keep original function key and operating key layout constant.On this basis, the layout of 26 of major key panel character keys and 4 punctuation mark keys totally 30 key mappings is optimized.The Chinese everyday character provided by Peking University's Chinese language research centre (CCL) corpus and word be the high frequency words that provides of the high frequency words that provides of table, British National Corpus (BNC) and word frequency list and American National corpus (ANC) and word frequency list frequently, add up the situation of each character in Chinese pinyin and english vocabulary, comprise the frequency that each character occurs, the situation of two hand sequence alternates, and the information such as the identical finger situation of knocking continuously.With the load balancing of right-hand man, the load of middle row is maximum, and the frequency of two hand sequence alternates is maximum, and the frequency of identical finger is minimum carries out mathematical modeling for objective function and tries to achieve optimum solution.

Keyboard of the present invention, comprise major key panel, character keys, function key, operating key, the character keys of upper row 10 location arrangements in major key panel, is respectively from left to right: " K " key, " Q " key, " X " key, " G " key, " D " key, " J " key, " M " key, " O " key, " R " key, " L " key;

The final layout in keyboard major key panel of the present invention as shown in Figure 1, for English and the comprehensive input condition of Chinese spelling be: the load of left hand is 51.63% of workload, the load of the right hand is 48.37% of workload, the load of middle row reaches 64.42% of workload, the frequency of two hand sequence alternates is 48.99%, and the number of times that identical finger knocks continuously only accounts for 5.70% of workload.

Randomly draw text data and carried out a large amount of test, the novel keyboard indices after test result optimization is all obviously better than qwerty keyboard.Select below wherein one section of Chinese pinyin text and English text test result as shown in the table:
