Description
Technical field
The utility model relates to a kind of key mapping alignment placement of keyboard, relates in particular to a kind of keyboard of suitable input in Chinese.
Background technology
Distribution of the keys on the computer keyboard since the mode that adopts the QWERTY English letter keyboard to arrange almost without any change.But the QWERTY keyboard exists the place of numerous inadequate science owing to directly continued to use the arranging key locations of typewriter.During Larsen Xiao Ersi initial design printer-keyboard layout, 26 English alphabets are arranged in order by the standard order, after the typist was familiar with keyboard layout, along with the raising of typing speed, the inner rotation bar phenomenon that is stuck often appearred in printer.Because the limitation of epoch and technology, Xiao Ersi has readjusted the key-position letter order, has designed the QWERTY keyboard layout, limits to greatest extent the speed of stroking.Along with the progress in epoch, there has not been now technical obstacle, but still continue to use the QWERTY keyboard of restriction typing speed.And the letter layout of QWERTY keyboard,, exists and the inconsistent problem of Chinese characters phonetic alphabet word frequency when particularly Chinese spelling is inputted being used for input in Chinese take english input as background designs.This problem is not resolved on soft keyboard so far.In addition, do not have specific keyboard for the keyboard beginner.
The utility model content
The purpose of this utility model provides a kind of soft keyboard of suitable Chinese spelling input, the problems such as typing speed when having solved existing QWERTY keyboard restriction input in Chinese.Concrete technical scheme is as follows:
A kind of improved structure of computer keyboard, its letter layout is three row, comprise left hand key district, right hand key zone and public key zone, the both sides of described public key zone are adjacent with described right hand key zone with described left hand key district respectively, described left hand key district and described right hand key zone are English alphabet of a keys arrangement, and described public key zone is one or two English alphabet of keys arrangement.
Described public key zone be arranged as three row, one row, wherein, two zeds and Y are arranged on the key mapping of the first row, be I on the key mapping of the second row, be C on the key mapping of the third line.
The key mapping in described left hand key district has three row, on the key mapping of the first row from left to right letter arrange and be respectively M, T, W, B,
On the key mapping of the second row from left to right letter arrange and be respectively D, O, G, H, be respectively from left to right V, P, K on the key mapping of the third line.
The key mapping of described right hand key zone has three row, on the key mapping of the first row from left to right letter arrange and be respectively S, J, L, X,
On the key mapping of the second row from left to right letter arrange and be respectively N, A, E, U, be respectively from left to right Q, R, F on the key mapping of the third line.
The key mapping surface of described left hand key district, described public key zone and described right hand key zone is coated with respectively different colors
Distinguish.
The soft keyboard of improvement letter layout of the present utility model is compared with the keyboard of existing qwerty conventional in layout and is had the following advantages: can obtain faster input speed 1.; 2. the error rate when inputting is lower; 3. total distance that thumb moves when inputting is shorter; 4. the complicacy of moving in the time of alleviating the fatigue strength of finger and lower keystroke when inputting; 5. by research new soft keyboard layout and qwerty soft keyboard layout are had the tested of equal input experience, find that new soft keyboard layout is easier to study.
Description of drawings
Fig. 1 is distribution of the keys figure in the keyboard structure of the present utility model;
Fig. 2 is the distribution diagram of each finger in the letters case district in the keyboard structure of the present utility model.
Embodiment
Fig. 1 is the alphabetical layout viewing of soft keyboard of the present utility model; Fig. 2 is the distribution diagram of each finger in the letters case district in the soft keyboard of the present utility model.
As shown in Figure 2, letters case divides three districts on the keyboard of the present utility model, left hand key mapping, right hand key-position area and public key-position area.Theoretical according to the keyboard layout of Charles Dvorak: the frequency of utilization of key mapping from second row to first row, the 3rd row, and the right hand is to left hand, forefinger is arranged to little finger successively frequency reducing.Be that the key mapping frequency permutation is deferred to three principles:
1, second row〉first row〉the 3rd row;
2, public area〉right hand region〉the left hand district;
3, forefinger〉middle finger〉third finger〉little finger of toe.
The frequency statistics that occurs in conjunction with the Chinese characters in common use phonetic alphabet (for the number designation among Fig. 2, frequency number of times that 1 this letter of expression I occurs is the highest, the like, it is minimum that 26 these letters of expression V occur).The soft keyboard alignment placement that must make new advances.This soft keyboard alignment placement is compared with traditional QWERTY keyboard layout, under Chinese spelling input condition, the advantage of the following aspects is arranged:
1, gets faster input speed.
By to from 10 not the tested of contacted computer test, the experimental data that obtains shows, the typing speed of using the application's keyboard to obtain is 7.45 seconds/word, and the typing speed of using conventional keyboard to obtain is 5.60 seconds/word.Above data are carried out statistical study, use independent sample T check, t=4.47, p=0.00＜0.05, so this difference is significant, namely the soft keyboard of this patent is better than traditional qwerty keyboard in input speed.
Error rate when 2, inputting is lower.
By to 10 never the tested of contacted computer test, the experimental data that obtains shows, the error rate that the soft keyboard of use this patent obtains is 7.2%, and the error rate of using traditional Q WERTY keyboard to obtain is 11.1%, thereby the soft keyboard error rate when input that can find this patent is lower than traditional Q WERTY keyboard.
Total distance that thumb moves when 3, inputting is shorter.
4, input the complicacy of moving in the time of alleviating the fatigue strength of finger and lower keystroke.
Article three, and the 4th can illustrate with the principle of this keyboard foundation.Because the arrangement of this keyboard is to arrange height according to the Chinese characters in common use word frequency, keyboard layout in conjunction with Charles Dvorak is theoretical, and with reference to two letters that link to each other of the normal appearance Frequency Design that occur in the Chinese phonetic alphabet commonly used, the finger that the most frequently used key mapping is placed in the people is the position of easy click, so during underway civilian spelling input, total distance that thumb moves is shorter than traditional qwerty keyboard.Because displacement has been lacked, click has made things convenient for, and when the soft keyboard that uses this patent is inputted, can alleviate the fatigue strength of finger and lower the complexity of keystroke action.
By research new soft keyboard layout and qwerty soft keyboard layout are had the tested of equal input experience, find that new soft keyboard layout is easier to study.
By to 10 never contacted computer tested carry out of short duration training, the data that obtain show, after training, use the tested typing speed of this patent soft keyboard layout to improve 2.67 seconds/word, and use the tested typing speed of traditional Q WERTY keyboard layout only to improve 2.01 seconds/word, thereby the soft keyboard layout that can find this patent is easier to study than traditional Q WERTY.
In addition, because this new keyboard has been done clear to the subregion of each thumb of right-hand man, and marks out different responsible districts with different colors, for the keyboard beginner, greatly improved their typing speed, and standard the correct gesture posture of typewriting.
Being preferred embodiment of the present utility model only in sum, is not to limit practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
