Disclosure of Invention
In view of the above-mentioned situation and problems, the present invention is directed to: the virtual keyboard rearranges 26 English letters according to the sequence of an alphabet, and enables the commonly used vowel letters to be continuously arranged together, and then combines a Chinese character pinyin input method based on the virtual keyboard, so that a user can quickly become familiar with new keyboard layout without too much adaptation time and memory process, and because the 5 commonly used vowel letters are continuously arranged together, each complete pinyin only needs one to two times of clicking or sliding operation, the Chinese character pinyin input efficiency is greatly improved, and the virtual keyboard is more favorable for market popularization and application of the technical patent of the invention.
In order to achieve the above purpose, the embodiment of the invention adopts the following technical scheme:
a virtual keyboard based on a touch screen device, characterized by:
26 English letter keys are displayed on the virtual keyboard; and the number of the first and second electrodes,
the letter keys a, e, i, o and u are arranged in series;
the rest letter keys b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, w, x, y and z are respectively arranged behind the letter keys a, e, i, o and u according to the sequence of 26 standard English alphabets;
the 'letter keys a, e, i, o and u are arranged continuously' means that the system arranges 5 English vowel letter keys a, e, i, o and u together according to a row or a column or along a regular curve to form a continuous vowel letter key area;
the "remaining alphabet keys b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, w, x, y, z are arranged after the alphabet keys a, e, i, o, u, respectively, in the order of 26 english alphabets" more specifically means:
the letter keys b, c and d are sequentially arranged behind the letter key a and in front of the letter key e;
the letter keys f, g and h are sequentially arranged behind the letter key e and in front of the letter key i;
the letter keys j, k, l, m and n are sequentially arranged behind the letter key i and in front of the letter key o;
the letter keys p, q, r, s and t are sequentially arranged behind the letter key o and in front of the letter key u;
letter keys v, w, x, y and z are sequentially arranged behind the letter key u;
the virtual keyboard based on the touch screen device is characterized in that: the keyboard can also be provided with at least one of common function keys such as a backspace key, a space key, a number symbol switching key, a capital and lower case switching key and the like.
In a preferred embodiment, the letter keys of the virtual keyboard are arranged in a row from top to bottom, and located on the left side of the screen, and the rest of the letter keys are located behind the letter keys a, e, i, o, and u, respectively, so as to form a letter key layout with 5 rows and 6 columns.
Since the letter keys on the virtual keyboard are arranged in the order of 26 English alphabets as a whole, it is easy for the user to remember the positions of the letter keys, and no extra effort is required to adapt to the new keyboard layout.
Because the vowel letters on the virtual keyboard are continuously arranged together, when the vowel part of the pinyin of the Chinese character is input, the advantages of the touch screen can be fully utilized: the touch pen can be clicked, slid or dragged and the like, and the distance of the finger or the touch pen needing to move is greatly reduced, so that the input speed and efficiency are improved. Furthermore, even if the input is performed by simply clicking each pinyin character, the input efficiency of the pinyin for a chinese character is improved because the distance moved by the finger is reduced based on the layout of the keyboard.
In order to better understand the scheme of the invention, before explaining the method for inputting Chinese character pinyin by using the virtual keyboard, the basic characteristics of Chinese character pinyin are simply combed;
the Chinese character pinyin mainly comprises an initial part and a final part, wherein:
the initial part comprises: 23 b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, w, x, y, z, zh, ch, sh, etc.;
the final part comprises: a, ai, an, ao, ang, e, ei, en, er, eng, i, ia, ie, in, iu, ing, ian, iao, iang, iong, o, ou, ong, u, ua, ui, ue, uo, un, uai, ua, uang, v, etc. for a total of 33;
it can be seen that the initial consonants are single-letter initial consonants except for zh, ch and sh which are composite initial consonants;
except for a, e, i, o, u and v, the rest of the vowel part are compound vowels and are divided into two types:
1) compound vowels composed of vowels, such as: ai, ao, ei, ia, iao, ie, iu, ou, ua, ui, uo, uai, etc.;
2) nasal vowels consisting of vowels plus n or ng, such as: an, ang, en, eng, in, ing, ong, un, ung, iang, iong, uang, etc.
Because the vowels v and ve (commonly written as ue) are not commonly used in practical use, 32 Chinese characters including nv, nve, lv and lve are related in total, and the vowel er is also not commonly used, the technical scheme of the invention has no special design for the input modes of the Chinese characters, and the input of the Chinese characters can be accepted by using a common letter click key.
In summary, based on the characteristics of pinyin of Chinese characters and in combination with the improved layout mode of the virtual keyboard, the invention provides an input method using the virtual keyboard based on touch screen equipment, which comprises the following steps:
an input method using a virtual keyboard based on a touch screen device is characterized by comprising the following input modes:
1) by directly clicking the corresponding letter keys, the input of all the single initials or the unit initials and finals is obtained, which comprises the following steps: b, c, d, f, g, h, j, k, l, m, n, p, q, r, s, t, w, x, y, z and a, e, i, o, u, v;
2) the input of the composite initial consonant zh, ch and sh is obtained by clicking the letter keys z, c and s and dragging and sliding the distance of at least one letter key size and releasing the finger (or a touch pen tool);
3) by clicking a vowel key and sliding through other vowels as needed in the vowel key area, releasing the finger (or a touch pen tool) to complete all the compound vowels combined by vowels, including: ai, ao, ei, iu, ou, uo, ui, ue, ua, ie, ia, iao, uai;
4) through clicking a vowel button and/or sliding through other vowels that need in the vowel button region, drag the slip to the vowel button region again outside, unclamp the finger (or stylus instrument), accomplish all compound vowels that make up by vowel and n or ng, include: an, en, in, un, ang, eng, ing, ong, ian, iang, iong, ua, uang, etc., wherein: when the distance of dragging and sliding is larger than 1 letter key size and smaller than 2 letter key sizes, releasing the finger (or a stylus tool) to obtain the input of an, en, in, un, ian and uan; when the dragging and sliding distance is larger than 2 letter key sizes, the finger (or a stylus tool) is released, and the inputs of ang, eng, ing, ong, iang, iong and uang are obtained;
in the input modes 2) and 4), "the distance of dragging and sliding is greater than 1 letter key size," wherein "the letter key size" refers to the size of one letter key defined on the virtual keyboard of the current device.
In the input mode 3), the "slide through other required vowels in the vowel button region", more specifically, the start point of the sliding motion is located on the first vowel button of the compound vowel, the end point of the sliding motion is located on the last vowel button of the compound vowel, the sliding motion passes through the vowel button at the middle position of the compound vowel, and the sliding path is located in the vowel button region;
in the input mode 4), the action starting point of the drag sliding is positioned in the vowel letter key area, the action finishing point of the drag sliding is positioned outside the vowel letter key area, and the drag sliding direction is not limited; the system judges whether the current input action is the input of the nasal sound and the vowel or the input of the compound initial part by detecting whether the starting point position of the current dragging sliding is positioned in the vowel letter key area in real time, and no ambiguity is generated.
In the definition of the touch screen operation gesture, the 'dragging' and the 'sliding' are not obviously different, the 'dragging' expression is used in the scheme of the invention to more vividly explain the key when sliding from the vowel key area to the outside, for example, an or ang is obtained by clicking the letter a and dragging the letter a for a certain distance, because n and g are not in the area of the dragging sliding, and n or ng is more added behind the clicked vowel letter by dragging, so that the situation that how to obtain all the input similar to the nasal vowel can be more vividly explained.
In summary, the most prominent technical advantages of the present invention are that the input mode of the pinyin for Chinese characters is improved by continuously arranging the vowel keys commonly used for pinyin for Chinese characters, especially the input of the vowel part of the pinyin for Chinese characters can be realized by clicking, sliding or dragging in a short distance, the advantages of the touch screen are fully utilized, and then the input of each pinyin can be completed by only clicking or dragging and sliding actions once or twice, thereby greatly improving the efficiency of the input of the pinyin for Chinese characters. And because the whole arrangement sequence of all letter keys is the sequence of the standard 26 English alphabets familiar to most users, the users are greatly facilitated to get familiar with the new keyboard layout, the process that the users interrupt the searching process due to unfamiliar letter key positions during inputting is avoided, and the input experience of the users is improved.
