Description
Technical Field
The invention relates to the technical field of input methods, in particular to a virtual keyboard based on touch screen equipment and an input method thereof.
Background
At present, on a touch screen device such as a smart phone, common virtual keyboards are mostly laid out in a mode of QWERTY full keyboards or digital Sudoku and the like, and both the two virtual keyboards are based on a layout mode of a traditional physical keyboard.
However, the layout mode of virtual keyboards such as a QWERTY full keyboard and a digital squared figure cannot be applied to a small-sized touch screen device similar to an apple intelligent watch, taking the size of a touch screen of an apple 1-generation intelligent watch as an example, the screen size is about 1.97 inches to 2.2 inches, namely, the side length is between 38mm to 42mm, an area which is close to the edge of the screen and cannot be used is removed, the side length of an area where keys are arranged is only about 36mm to 40mm, and the layout mode of the virtual keyboard of the QWERTY full keyboard is obviously inapplicable due to excessive keys; although the number of keys of the nine-grid virtual keyboard is much less than that of a QWERTY full keyboard, the nine-grid virtual keyboard has the defects that the coincident code rate is high, a screen space needs to be reserved for selecting the candidate Chinese character pinyin combination, and in addition, the candidate characters or words and other functional keys including a confirmation key, a space key, a deletion key, a digital symbol switching key and the like need to be displayed in space, so that the nine-grid virtual keyboard layout cannot be suitable, and even if the nine-grid virtual keyboard is applied reluctantly, the input experience is poor.
However, no disclosed virtual keyboard and input method thereof are found in the current market, which can be well applied to devices similar to small touch screens of apple smartwatches, and besides a voice input method, no technical scheme for inputting pinyin of Chinese characters applicable to the virtual keyboard and the input method thereof is available, so that a new technical scheme is urgently needed to solve the problem.
Disclosure of Invention
In view of the above-mentioned situation and problems, the present invention is directed to: the virtual keyboard is provided with 5 English vowel letter keys a, e, i, o and u which are continuously arranged, the 5 English vowel letters are used as indexes according to the sequence of letters on 26 standard English alphabets to obtain the input of consonant letters after corresponding vowels, and the input method based on the virtual keyboard is combined to ensure that the input of each complete Chinese character pinyin only needs one to two times of clicking or sliding operation, so that the information input on a small-size touch screen is possible and the input experience is good.
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:
5 English vowel keys a, e, i, o and u are displayed on the virtual keyboard;
and the letter keys a, e, i, o, u are arranged consecutively;
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 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, as shown in fig. 1, are arranged in a row from top to bottom, and are located on the left side of the screen.
Because 5 vowel letter keys on this virtual keyboard arrange together in succession for when the vowel part of input chinese character pinyin, can make full use of touch-sensitive screen's advantage: can be clicked, slid or dragged, and the distance that the finger (or a stylus tool) needs to move is greatly reduced, thereby improving the speed and the efficiency of input.
In order to facilitate better understanding of 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, ue, 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, 4 pinyin syllables such as nv, nve, lv, lve and the like are related, 32 Chinese characters are total, and in addition, the vowel er is not commonly used, the technical scheme of the invention has no special design for the input modes of the vowels v and ve, and the input of the vowels v and ve can be accepted by using a common click letter 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 clicking the area outside each vowel letter key, obtaining the switching display of each consonant letter after the corresponding vowel letter on the vowel letter key area, including: b, c, d after a; f, g, h after e; j, k, l, m, n after i; p, q, r, s, t after o; v, w, x, y, z after u; then the finger (or the touch pen tool) continuously slides to the needed consonant letter key, and the finger (or the touch pen tool) is released to obtain the input of the single initial consonant;
2) as described in the input mode 1), when a finger (or a stylus tool) is slid onto the letter keys z, c, s; dragging and sliding the finger (or a touch pen tool) to the area outside the vowel letter key area by at least one letter key size, and releasing the finger (or the touch pen tool) to obtain the input of the composite initial consonant zh, ch and sh;
3) the input of single vowel is obtained by clicking letter keys a, e, i, o and u and releasing a finger (or a stylus tool);
4) by clicking a vowel key and sliding through other vowels as needed in the vowel key area, releasing a finger (or a touch pen tool) to obtain all compound vowels combined by vowels, the method comprises the following steps: ai, ao, ei, iu, ou, uo, ui, ue, ua, ie, ia, iao, uai;
5) 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 distance of dragging and sliding is larger than 2 letter key sizes, the finger (or the stylus tool) is released, and the input of ang, eng, ing, ong, iang, iong and uang is obtained.
In the input mode 1), the "obtaining the display of each consonant letter after the corresponding vowel letter on the original vowel letter key region by clicking the region outside each vowel letter key" means that when the touch point of the finger (or the stylus tool) is located in the region of a row or column where a vowel letter is located and outside the vowel letter key, the system hides each vowel letter on the vowel letter key position and switches and displays the vowel letter after the vowel letter and each consonant letter before the next vowel letter;
for example: when the touch point of the finger (or the stylus tool) is located on the row where the vowel a is located, and the finger (or the stylus tool) is not located on the letter key a itself, the system hides the displayed a, e, i, o, u in the original vowel key area, and switches to display the 3 consonant letters of b, c, d.
In the input modes 2) and 5), "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 modes 2) and 5), "drag and slide outside the vowel key region", the action start point of the "drag and slide" is located inside the vowel key region, the action end point is located outside the vowel key region, and the direction of drag and slide is not limited.
In the input modes 4) and 5), "the vowel letter slides through other required vowels in the vowel letter key region", more specifically, the start point of the sliding motion is located on the first vowel letter key of the compound vowel, the end point of the sliding motion is located on the last vowel letter key of the compound vowel, the sliding motion passes through the vowel letter key at the middle position of the compound vowel, and the sliding path is located in the vowel letter key region.
The user can combine the input modes according to the actual input requirement to complete the input of a complete pinyin.
In the definition of the actual 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 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 5 vowels are indexed to corresponding consonant letters according to the sequence of 26 english alphabets, and vowel keys are continuously arranged, so that the input of the vowel portion of the pinyin for a chinese character can be realized by clicking, sliding or dragging within a short distance, and the advantages of a touch screen are fully utilized, and thus the input of each pinyin can be completed only by clicking or dragging and sliding actions of one to two times. And the virtual keyboard layout occupies small screen space, and the input method can be suitable for small-size touch screen equipment similar to an apple intelligent watch, compared with a nine-square-grid layout mode, pinyin input by the input mode does not have a repeated code phenomenon, the screen space for displaying pinyin repeated codes is saved, and the input experience is better.
