Background

The user can input a character string into the terminal using a virtual keyboard provided by the input method.

For the Chinese input method, the virtual keyboard generally includes a full keyboard and a multi-keyboard. The full keyboard generally includes virtual keys corresponding to all pinyins. The multi-keyboard type virtual keyboard can be suitable for terminals with smaller display screens, such as smart phones and the like, the multi-keyboard comprises a plurality of stages of virtual sub-keyboards, and each stage of sub-keyboard can comprise a part of virtual keys corresponding to pinyin. During the input process, the other level of sub-keyboard can be popped up by triggering the virtual keys on the sub-keyboard.

However, the experience of using a multi-keyboard for inputting Chinese characters in taiwan is not good at present, and since syllables such as initial consonants, vowels and intermediate vowels are required to be used when Chinese characters are input in taiwan, the complex syllable composition mode causes that in the case of the multi-keyboard, virtual keys corresponding to different syllables can be displayed on the same-level sub-keyboard along with different input conditions, and the number of the virtual keys is different, so that the rule is difficult to find. When a user inputs the input, the user cannot know which virtual keys corresponding to syllables exist in the sub-keyboard popped up by triggering a certain virtual key in the current level of sub-keyboard, or the user can find the virtual key corresponding to the required syllable only after the user needs to be familiar with the virtual key after popping up a new level of sub-keyboard, so that the input experience of the user is reduced.

Detailed Description

Embodiments of the present application are described below with reference to the accompanying drawings.

At present, the multi-keyboard input for the Chinese characters in Taiwan is not good in use experience, because syllables such as initial consonants, simple or compound vowels and intermediate vowels are needed when the Chinese characters are input in Taiwan, the initial consonants, the simple or compound vowels and the intermediate vowels respectively comprise a plurality of syllables, and complex syllable composition modes exist among the syllables, such as initial consonants, the intermediate vowels, the simple or compound vowels, the initial consonants, the final vowels, the intermediate vowels and the like. When the traditional multi-keyboard faces the complex syllable composition modes, the display rule of the same-level sub-keyboard under different input conditions is not well planned, so that the same-level sub-keyboard can display virtual keys corresponding to different syllables under the condition of the multi-keyboard along with different input conditions, the number of the virtual keys is different, the rule is difficult to find, and the input experience of a user is reduced.

Taking the example that the conventional multi-keyboard includes the primary sub-keyboard and the secondary sub-keyboard, when the user inputs the initial consonant "b" through the virtual keys of the primary sub-keyboard, assuming that the next syllables that can be combined with "b" include 10, the secondary sub-keyboard may display 10 virtual keys for the user to find the virtual key corresponding to the desired syllable; when the user inputs the initial "d" through the virtual keys of the primary sub-keyboard, assuming that 25 syllables that can be combined with "d" are included, the secondary sub-keyboard may display 25 virtual keys for the user to find the virtual key corresponding to the desired syllable.

Therefore, under different input conditions, the same-level sub-keyboard can display virtual keys corresponding to different syllables, the number of the virtual keys is different, the rule is difficult to find, a user cannot know which virtual keys corresponding to the syllables exist in the sub-keyboard popped up by triggering a certain virtual key in the current-level sub-keyboard, or the user can find the virtual key corresponding to the required syllable after the user needs to be familiar with the virtual key after popping up a new-level sub-keyboard, and the input experience of the user is reduced. Even the number of virtual keys of a certain level of sub-keyboard can be too large under some conditions, if too many virtual keys are displayed on the same page, the virtual keys can be too small, and false touch is easily caused; if too many virtual keys are displayed in pages, it may be difficult for the user to find the virtual key corresponding to the desired syllable, and the difficulty of finding the rule may also be increased.

Therefore, the virtual keyboard provided by the embodiment of the application can display all levels of sub-keyboards by using fixed display logics, so that the number of virtual keys in each sub-keyboard is small, the sub-keyboards are relatively fixed under different input conditions, a user is easy to know and master rules, and the input efficiency and experience of the user are improved.

It should be noted that, in this embodiment, the medium initial may be used as an initial or a final, each of the initial and the final may be a syllable, one or more syllables of the initial and the final may be combined to form a syllable string, and the input of the chinese character may be implemented by using the syllable string.

the virtual keyboard provided by the embodiment of the application is described in detail below with reference to the accompanying drawings.

Referring to fig. 1a, fig. 1a shows an exemplary view of a virtual keyboard for inputting chinese characters to a terminal using an input method. The virtual keyboard includes three levels of sub-keyboards, a first level sub-keyboard 101, a second level sub-keyboard 102, and a third level sub-keyboard 103. The first-level sub-keyboard 101 is configured to display virtual keys corresponding to initials, the second-level sub-keyboard 102 is configured to display virtual keys corresponding to initials and tones, the third-level sub-keyboard 103 includes sub-keyboards of multiple predetermined final combination manners, and fig. 1a illustrates a sub-keyboard of one predetermined final combination manner included in the third-level sub-keyboard 103.

The input method mentioned in the embodiments of the present application may be a coding method adopted for inputting various syllables to the terminal. It should be noted that the input method in the embodiment of the present application may be a commonly used chinese input method, for example, a pinyin input method, a ZhuYin input method, or the like. Fig. 1a is a diagram of a virtual keyboard, which is not limited in the embodiment of the present application.

It should be noted that, when the input method is a phonetic notation input method, the virtual keyboard provided in the embodiment of the present application may be as shown in fig. 1 b. In fig. 1b, the virtual keys in each sub-keyboard correspond to the ZhuYin symbol, and the ZhuYin symbol in fig. 1b corresponds to the syllable located at the same position in fig. 1a, for example, the ZhuYin symbol "b" in fig. 1b corresponds to the syllable "b" located at the same position in fig. 1 a.

in this embodiment, the second-level sub-keyboard 102 is displayed by triggering a virtual key in the first-level sub-keyboard 101, and one sub-keyboard in the third-level sub-keyboard 103 is displayed by triggering a virtual key in the second-level sub-keyboard 102. That is to say, the display logic of the three-level sub-keyboard provided in the embodiment of the present application is relatively fixed, and is easy to be mastered by a user, even if the input condition changes, the display is also the first-level sub-keyboard to the user, when the user triggers a certain virtual key in the first-level sub-keyboard, the display is performed on the second-level sub-keyboard to the user, and when the user triggers a certain virtual key in the second-level sub-keyboard, the display is performed on one sub-keyboard in the third-level sub-keyboard to the user.

It should be noted that, the sub-keyboard mentioned in the embodiment of the present application refers to the remaining area on the input method display interface except the common virtual key area shared by the three-level sub-keyboards. For example, the first level sub-keyboard 101, the second level sub-keyboard 102, and the third level sub-keyboard 103 are regions indicated within dashed boxes in fig. 1a and 1 b.

The sub-keyboards generally include virtual keys for displaying syllables or tones, and in some cases, the virtual keys in a sub-keyboard may include a switch key and a blank key because a certain sub-keyboard displays too few syllables. The public virtual key area can comprise symbol keys, number keys, space keys, line feed keys, backspace keys, confirmation keys and the like, and the public virtual key area can not be changed along with the switching of the sub-keyboards in different levels and can not be changed along with the sub-keyboards in different preset final combination modes displayed by the third-level sub-keyboard.

In the present embodiment, the first level sub-keyboard 101 is constructed according to the following manner: according to the combination rule of the initial consonants and the final consonants in the Chinese language, the initial consonants with the similarity of the combination rule of the final consonants and the final consonants meeting a first preset condition form an initial consonant set; and constructing a corresponding first-level sub-keyboard 101 according to the obtained initial consonant set.

The combination rule of the initial consonants and the final consonants mentioned in the embodiment of the application is used for specifying which final consonants can be input next after the initial consonants are input, so that the input final consonants and the initial consonants can be combined into syllable strings to realize the input of the Chinese characters.

The combination rule similarity may refer to a similarity degree between finals combined with different initials, for different initials, the higher the combination rule similarity is, the higher the similarity degree between finals combined with different initials is, when the combination rule similarity satisfies a first preset condition, it may be considered that the similarity degree between finals combined with these different initials is very high, in order to facilitate a subsequent determination of a certain sub-keyboard in a third-level sub-keyboard according to initials in a targeted manner, the different initials may be divided into the same initial set.

It is understood that for different initials, the combination rule similarity may be measured by the number of finals having the same final in the finals combined with the different initials into the syllable string, and then the first preset condition may be that the number of finals having the same final in the finals combined with the different initials into the syllable string reaches the first threshold.

For example, the initials "b", "d", and "t", the finals combined with "b" into a syllable string may include "an", "o", "a", the finals combined with "d" into a syllable string may include "an", "ong", "uan", "iu", and the finals combined with "t" into a syllable string may include "an", "ong", "uan". Wherein, three identical vowels "an", "ong" and "uan" exist in the vowel combined with "d" into the syllable string and the vowel combined with "t" into the syllable string, the vowel combined with "b" into the syllable string and the vowel combined with "d" into the syllable string, or only one identical vowel "an" exists in the vowel combined with "t" into the syllable string, if the first threshold is 2 at this time, the initial consonants with the same vowel quantity satisfying the first threshold are "d" and "t", then "d" and "t" can form an initial consonant set. "b" can be located in another set of initials, which is a set of initials other than "d" and "t".

Thus, according to the combination rule of the initials and the finals in the chinese language, the initials may be divided into a plurality of initial sets, for example, as shown in fig. 2, 4 initial sets are included in fig. 2, which are an initial set 201, an initial set 202, an initial set 203, and an initial set 204, respectively, each initial set includes at least one initial, and the initial included in each initial set may be as shown in the dashed box in fig. 2.

Then, a corresponding first-level sub-keyboard 101 may be constructed according to the obtained initial consonant sets, wherein each virtual key in the first-level sub-keyboard 101 corresponds to an initial consonant in each initial consonant set in fig. 2. Taking the initial consonant set obtained in fig. 2 as an example, the first-level sub-keyboard 101 shown in fig. 1a can be constructed according to the initial consonant set shown in fig. 2, and when a user triggers a virtual key in the first-level sub-keyboard 101, the initial consonant corresponding to the virtual key is input.

It should be noted that in some cases, the syllable string corresponding to some chinese characters may not include the initial consonant, for example, the syllable string corresponding to the chinese character "a" is "an", but the display logic of the keyboard provided in the embodiment of the present application is fixed, and it is necessary to display the second-level sub-keyboard by triggering the virtual key in the first-level sub-keyboard, and the syllable string "an" does not include the initial consonant, that is, the second-level sub-keyboard cannot be displayed by triggering the virtual key corresponding to the initial consonant in the first-level sub-keyboard. In this case, when dividing the initial set, the zero initial 205 may be added, so that a first level sub-keyboard including virtual keys corresponding to the zero initial 205 may be constructed, as shown in the first level sub-keyboard 101 in fig. 1 a. In this embodiment, the zero initial consonant can be regarded as a special expression form of the initial consonant, and for convenience of the following description of the predetermined combination manner of the final consonants, the zero initial consonant can be regarded as an initial consonant set, and this embodiment may include 5 initial consonant sets.

The virtual key "toggle" in the first level sub-keyboard 101 may correspond to a zero initial 205, which is entered when the user triggers the virtual key "toggle" to indicate that the string of syllables the user wishes to enter does not include the initial in the initial set.

For example, if the user wishes to enter a syllable string of "an" since the first level sub-keyboard 101 is first presented to the user and the initial consonant is not included in "an", then the user may trigger the virtual key "toggle" in the first level sub-keyboard 101, thereby presenting the second level sub-keyboard 102 to the user so that the user continues to trigger the desired virtual key in the second level sub-keyboard 102.

In the present embodiment, the second level sub-keyboard 102 is constructed according to the following manner: and constructing a corresponding second-level sub-keyboard according to the medium letters and the tones, wherein the number of the virtual keys in the second-level sub-keyboard is the same as that of the virtual keys in the first-level sub-keyboard, so that when the first-level sub-keyboard is switched to the second-level sub-keyboard, the key positions of the virtual keys are fixed, the sizes of the virtual keys cannot be changed, and users can conveniently know the virtual keys at all levels.

wherein the middle mother may include three categories, "i", "u" and "ü", respectively, and the tones may include 5 categories, "," ˇ "," and "", respectively, as shown in fig. 3. the virtual keys in the second level sub-keyboard 102 correspond to the middle mother and/or the tones in fig. 3.

in this embodiment, the third level sub-keyboard is constructed according to the following manner: determining a third-level sub-keyboard corresponding to the vowel according to the obtained initial consonant set, wherein the third-level sub-keyboard comprises sub-keyboards in various preset vowel combination modes; the preset vowel combination mode of any sub-keyboard is determined according to the initial consonant set and the intermediate vowels and/or the tones.

It should be noted that, in this embodiment, the final combination manners are preset according to the initial set and the intermediate initials and/or tones, and the number of the initial set and the intermediate initials and/or tones combination manners determines the number of the types of the predetermined final combination manners, that is, the number of the sub-keyboards included in the third-level sub-keyboard, if 5 initial sets are included in this embodiment, each initial set may be combined with the intermediate initials and/or tones, respectively, in this embodiment, for each initial set, a sub-keyboard including a predetermined final combination manner may be determined according to the combination of the initial set and the tones, a sub-keyboard including a predetermined final combination manner may be determined according to the combination of the initial set and the intermediate initials "i", and a sub-keyboard including a predetermined final combination manner may be determined according to the combination of the initial set and the intermediate initials "u" or "ü", so that 5 × 3 — 15 final combination manners may be obtained for 5 initial sets, that each final combination manner may include a predetermined final combination manner, that is shown in fig. 15, that each final combination manner may include a predetermined final combination manner, that is shown in fig. 4 sub-keyboards.

The predetermined final combination mode of any sub-keyboard in the third-level sub-keyboard is determined according to the initial consonant set and the intermediate vowels obtained before, so that the original more final is divided according to the initial consonant set and the intermediate vowels, namely, a plurality of sub-keyboards in the third-level sub-keyboard are determined according to the first-level sub-keyboard and the second-level sub-keyboard in a targeted manner, therefore, the number of virtual keys capable of providing final input on each sub-keyboard is less, and the rules are easy to master by a user as each final in the sub-keyboards conforms to the predetermined final combination mode.

according to the technical scheme, the virtual keyboard comprises three levels of sub-keyboards, wherein the first level of sub-keyboards is used for displaying virtual keys corresponding to initials, the second level of sub-keyboards is used for displaying virtual keys corresponding to intermediaries and tones, and the third level of sub-keyboards comprises sub-keyboards in various preset final combination modes. Since each level of sub-keyboard is respectively planned with initial consonant, intermediate consonant and final, the display logic of each level of sub-keyboard is relatively fixed and is easy to be mastered by users, specifically, the second level of sub-keyboard is displayed by triggering virtual keys in the first level of sub-keyboard, and one sub-keyboard in the third level of sub-keyboard is displayed by triggering virtual keys in the second level of sub-keyboard. Because the number of the virtual keys in the second-level sub-keyboard is the same as that of the virtual keys in the first-level sub-keyboard, and the virtual keys in the first-level sub-keyboard are determined according to the initial consonant set formed by the initial consonants with the same combination rule with the vowels, the number of the virtual keys in the first-level sub-keyboard and the second-level sub-keyboard is small, and the virtual keys are relatively fixed under different input conditions and are easy to be familiar to users. The third-level sub-keyboard comprises sub-keyboards of a plurality of preset final combination modes, wherein the preset final combination mode of any sub-keyboard is determined according to the initial set and the intermediate consonants which are obtained before, so that the original more final is divided according to the initial set and the intermediate consonants, and equivalently, a plurality of sub-keyboards in the third-level sub-keyboard are determined according to the first-level sub-keyboard and the second-level sub-keyboard in a targeted manner, so that the number of virtual keys capable of providing final input on each sub-keyboard is less, and each final in the sub-keyboards conforms to the preset final combination mode, so that rules are easily mastered by a user, and the input efficiency and experience of the user are improved.

the third level of sub-keyboard comprises sub-keyboards of various preset final combination modes, after the virtual keys in the second level of sub-keyboard are triggered, the sub-keyboards of a certain preset final combination mode can be displayed for a user, and then, the sub-keyboards of which preset final combination mode is displayed and the characteristics of the final in the preset final combination mode are introduced.

If the target sub-keyboard in the third-level sub-keyboard is popped up according to triggering of the first virtual key in the first-level sub-keyboard and the second virtual key in the second-level sub-keyboard, the combination rules of the vowels and the target initial consonant set included in the preset vowel combination mode of the target sub-keyboard and the corresponding medium vowels of the second virtual key are the same, or the combination rules of the vowels and the target initial consonant set included in the preset vowel combination mode of the target sub-keyboard are the same; and the target initial set is an initial set in which the initial corresponding to the first virtual key is located.

for example, a user triggers a first virtual key "b" in the first-level sub-keyboard and a second virtual key "-" in the second-level sub-keyboard, wherein a consonant set "b p m" where a consonant "b" corresponding to the first virtual key is located is a target consonant set. Then, the target sub-keyboard in the third-level sub-keyboard is popped up to the user, as shown in 103 in fig. 1a, the predetermined combination of the finals of the target sub-keyboard includes finals "a ai an e ei en eng o ao ou", and the finals have the same combination rule with the target initial consonant set, i.e. the finals can be combined with the initial consonants in the target initial consonant set to form a syllable string.

It should be noted that, for a plurality of different initials in the first-level sub-keyboard, the combination rules of the different initials and the finals may be the same, if the different initials correspond to different virtual keys, when the virtual key corresponding to the initial in the first-level sub-keyboard that is the same as the combination rule of the finals is triggered, although the different virtual keys are triggered, the sub-keyboards in the predetermined final combination manner in the third-level sub-keyboard are likely to be the same. In this case, in order to reduce the number of virtual keys, thereby increasing the size of each virtual key and avoiding false touch caused by too small virtual keys, an implementation manner of the embodiment may be: in the first-level sub-keyboard, the input of similar initials is realized through one virtual key, and the similar initials are a plurality of initials with the same combination rule with the finals.

For example, "g" and "j" are the same as the vowel combination rule, so when constructing the first level sub-keyboard, "g" and "j" may correspond to the same virtual key, as shown by the virtual key labeled "g/j" in fig. 1 a.

It should be noted that, for a plurality of different intermediate alphabets in the second-level sub-keyboard, the similarity between the different intermediate alphabets and the vowel combination rule may be very high, and may even be the same, that is, the vowels combined with the intermediate alphabets to form a syllable string have very high similarity, if different intermediate alphabets correspond to different virtual keys, when triggering the virtual key corresponding to the intermediate alphabet in the second-level sub-keyboard with very high similarity to the vowel combination rule, although triggering different virtual keys, the sub-keyboards in the predetermined vowel combination mode in the third-level sub-keyboard are likely to be the same. In this case, in order to reduce the number of virtual keys, thereby increasing the size of each virtual key and avoiding false touch caused by too small virtual keys, an implementation manner of the embodiment may be: in the second-level sub-keyboard, the input of the similar medium letters is realized through one virtual key, and the similar medium letters are a plurality of medium letters with the similarity of the combination rule of the medium letters and the vowels meeting a second preset condition.

It is understood that, for different media letters, the combination rule similarity may be measured by the number of the same vowels in the vowels combined with the different media letters into the syllable string, and then the second preset condition may be that the number of the same vowels in the vowels combined with the different media letters into the syllable string reaches the second threshold.

for example, "u" and "ü" have high similarity to the vowel combination rule, so when constructing the second level sub-keyboard, "u" and "ü" may correspond to the same virtual key, as shown by the virtual key labeled "u/ü" in fig. 1 a.

It is understood that in order to reduce the number of virtual keys, thereby increasing the size of each virtual key and avoiding false touches caused by too small virtual keys, the number of virtual keys may be limited to a certain number. In this embodiment, the number of the virtual keys in the first-level sub-keyboard may be limited to be less than or equal to 15, and since the number of the virtual keys in the second-level sub-keyboard is the same as that of the virtual keys in the first-level sub-keyboard, the number of the virtual keys in the second-level sub-keyboard is less than or equal to 15.

based on the virtual keyboard provided in the embodiments corresponding to fig. 1a to fig. 4, this embodiment provides an input method based on a virtual keyboard, where the virtual keyboard is any one of the virtual keyboards in the embodiments corresponding to fig. 1a to fig. 4, and referring to fig. 5, the method includes:

S503, if the triggering operation aiming at the virtual keys in the second-level sub-keyboard is obtained, displaying one sub-keyboard in the third-level sub-keyboard.

optionally, one of the third-level sub-keyboards is determined according to the initial consonant corresponding to the virtual key in the first-level sub-keyboard and the intermediate consonant and/or the tone corresponding to the virtual key in the second-level sub-keyboard.

Optionally, after the one of the third-level sub-keyboards is displayed if the trigger operation for the virtual key in the second-level sub-keyboard is acquired, the method further includes:

If the triggering operation that the user selects the screen candidate item is obtained, displaying the first-level sub keyboard; the candidate items on the screen are generated according to the obtained initial consonant corresponding to the virtual key in the first-level sub-keyboard, the intermediate consonant and/or tone corresponding to the virtual key in the second-level sub-keyboard, and the final corresponding to the virtual key in one sub-keyboard in the third-level sub-keyboard.
