Fig. 2 A is the process flow diagram of a kind of cursor position defining method according to an exemplary embodiment, and as shown in Figure 2 A, this cursor position defining method can comprise the following steps.
In step 201, receive touch signal, determine the touch area corresponding to touch signal.
In order to the execution of subsequent step, use in the process of terminal user, user can touch terminal screen.Accordingly, terminal can receive the touch signal of user's touch terminal.Wherein, terminal is touch screen terminal.
Such as, user when touch-screen mobile phone inediting text, in order to cursor is moved to from current location need amendment word before or position afterwards, and then realize the change to this word, user first can click terminal screen.Now, terminal can receive the touch signal of user.
After terminal receives touch signal, terminal can determine the touch area corresponding to touch signal.When actual realization, user's finger drop point region in the terminal can be defined as touch area by terminal.
In step 202., at least two position candidate are determined according to touch area.
After terminal determines touch area, terminal can determine at least two position candidate according to touch area.Wherein, the step of terminal determination position candidate can comprise:
When touch area only includes a word, the gap of word both sides is defined as position candidate;
Such as, when keeping a diary in touch screen terminal with user, terminal determines that touch area is example, please refer to Fig. 2 B, and when touch area is for region shown in (1) figure, the A position of ' good ' both sides and B position can be defined as two position candidate by terminal.
When touch area comprises plural word, the gap between two words every in plural word is defined as position candidate.
Such as, please refer to Fig. 2 B, when touch area is for region shown in (2) figure, C position, D position and E position can be defined as position candidate by terminal simultaneously.
It should be noted that, in the present embodiment, touch area comprises word and can be understood as touch area and comprise the part viewing area that all viewing areas of this word or touch area comprise this word completely, and the present embodiment does not limit this.
In step 203, the evaluation factor of each position candidate is obtained.
Wherein, evaluation factor comprises the word cutting information of position candidate, phrase cutting information, statement cutting information, distance between position candidate and touch central point and user and chooses at least one in custom.
According to the difference of evaluation factor, the step that terminal obtains the evaluation factor of position candidate can comprise:
When evaluation factor comprises the word cutting information of position candidate, participle is carried out to the text message in target area, judge that whether position candidate is the centre position of a word, judged result is cut information as word, and the regional extent of target area is greater than or equal to the regional extent of touch area;
Terminal can carry out participle by participle technique to the text message in target area, judges that whether position candidate is the centre position of certain word, judged result is cut information as word.Wherein, the viewing area of the section at the viewing area that target area comprises touch area, be expert in touch area, place, touch area or whole viewing areas of place, touch area text message.
The viewing area of being expert at for touch area with target area is example, terminal by participle technique to touch area be expert in text message carry out participle after can obtain each word shown in Fig. 2 C.So when position candidate is D, terminal can judge that obtaining D is between word ' good beautiful ', and now by being used for, terminal can represent that position candidate D is positioned at the word cutting information of information alternatively corresponding to the D of position in the centre position of word.And when position candidate is E, terminal can judge to obtain the centre position that E is not in certain word, now terminal can represent position candidate E not in the word cutting information that the information in the centre position of word is determined by being used for.
When actual realization, terminal can also by the word of the word of the first predetermined number before position candidate, afterwards the second predetermined number or above-mentioned both combine, whether detect and combine the word that obtains is word in predetermined dictionary.If the word in predetermined dictionary, then illustrate that this position candidate is the centre position of a word, now, terminal can will be used for representing that position candidate is that the information in the centre position of word cuts information as word.And if not the word in predetermined dictionary, then illustrate that this position candidate is not the centre position of a word, now terminal can will be used for representing that position candidate is not that the information in the centre position of word cuts information as word.
When evaluation factor comprises the phrase cutting information of position candidate, participle is carried out to the text message in target area, judge that whether position candidate is the centre position of adjacent two words, judged result is cut information as phrase, and the regional extent of target area is greater than or equal to the regional extent of touch area;
Obtaining word with terminal, to cut the acquisition methods of information similar, terminal can also carry out participle by participle technique to the text message in target area, then judge whether position candidate is positioned at the centre position of adjacent two words, and judged result is cut information as phrase.
When actual realization, the word of at least two before position candidate can also combine by terminal, obtains the first phrase; After position candidate at least two word is combined, obtains the second phrase; Whether be word in default dictionary, and whether detect the second phrase be word in default dictionary if detecting the first phrase.When the first phrase and the second word are all the words in default dictionary, will be used for representing that position candidate is that the information of phrase cutting position cuts information as phrase; And when one or two phrases in the first phrase and the second phrase are not the words in default dictionary, then will be used for representing that position candidate is not that the information of phrase cutting position cuts information as phrase.
When evaluation factor comprises the statement cutting information of position candidate, judge whether position candidate is the position be in statement, and judged result is cut information as statement by semantic analysis technology;
By semantic analysis technology, terminal can judge that whether the semanteme of the statement that each word in the statement at position candidate place before position candidate forms is complete, or whether the semanteme of the statement that each word after judging position candidate forms is complete.If judged result is complete, then will be used for representing that position candidate is not that the information of statement cutting position is defined as statement cutting information; And if judged result is imperfect, then will be used for representing that position candidate is that the information of statement cutting position is defined as statement cutting information.
Such as, when position candidate is E, terminal can judge position candidate before the semanteme of ' landscape here good beautiful ' be complete, now terminal can will be used for representing that position candidate is not that the information of statement cutting position is defined as statement cutting information.And when if position candidate is D, then terminal can judge position candidate before ' landscape is here good ' and the semanteme of ' U.S. ' afterwards all imperfect, now, terminal can will be used for representing that position candidate is that the information of statement cutting position is defined as statement cutting information.
When evaluation factor comprises position candidate and touch the distance between central point, obtain the position of the touch central point corresponding to touch signal, calculated candidate position and the distance touched between central point;
When terminal receives touch signal, terminal can also obtain the position of the touch central point corresponding to touch signal, and then after determining position candidate, calculated candidate position and the distance touched between central point.
When evaluation factor comprise user choose custom time, when obtaining historical reception to touch signal, the display position of the cursor finally determined is arranged in left or the right of the corresponding touch area word adjacent with display position, the information got is defined as user and chooses custom.
What more meet user to make the cursor position determined chooses custom, when terminal historical reception is to touch signal, after terminal can obtain terminal demonstration cursor, before not receiving new touch signal, receive the text editing operations time target display position that user edits text message, determine that this display position is arranged in left or the right of the touch area word adjacent with this display position.When this display position determined is positioned at the left of word, illustrate that user habit custom when touching a certain word positions a cursor over the position of this word left; And if when this display position determined is positioned at the right of word, illustrate that user habit is when touching a certain word, custom positions a cursor over the position of the right of this word, so after terminal obtains above-mentioned information, the information determined is defined as user and chooses custom by terminal.
Wherein text editing operations be insert, delete, copy, at least one in cut and paste, the present embodiment does not limit this.
In step 204, for each position candidate, calculate the sub-score of evaluation factor.
For each position candidate, terminal can calculate the sub-score of each evaluation factor of this position candidate got.
According to the difference of evaluation factor, the step that terminal calculates the sub-score of evaluation factor can comprise:
When evaluation factor comprises word cutting information, then when word cutting information is when representing that position candidate is the centre position of word, the first numerical value is defined as the first sub-score of word cutting information; When word cutting information is when representing that position candidate is not the centre position of word, second value is defined as the first sub-score of word cutting information, the first numerical value is less than second value;
Such as, when word cutting information is when representing that position candidate is the centre position of word, first sub-score of this word cutting information can be defined as 0 by terminal, and when word cutting information is when representing that position candidate is not the centre position of word, the first sub-score that word can be cut information by terminal is defined as 1.
When evaluation factor comprises phrase cutting information, then when phrase cutting information is when representing that position candidate is the centre position of adjacent two words, third value is defined as the second sub-score of word cutting information; When word cutting information is when representing that position candidate is not the centre position of adjacent two words, the 4th numerical value is defined as the second sub-score of word cutting information, third value is less than the 4th numerical value;
When evaluation factor comprises statement cutting information, then while statement cutting information is when representing that position candidate is the position be in statement, the 5th numerical value is defined as the 3rd sub-score of statement cutting information; While statement cutting information is when representing that position candidate is not the position be in statement, and the 6th numerical value is defined as the 3rd sub-score of statement cutting information, the 5th numerical value is less than the 6th numerical value;
When evaluation factor comprises position candidate and touch the distance between central point, according to the 4th sub-score of default corresponding relation inquiry distance, default corresponding relation is position candidate and the negative correlativing relation between the distance touched between central point and the 4th sub-score;
When evaluation factor comprise user choose custom time, then when position candidate meet user choose custom time, the 7th numerical value is defined as the 5th sub-score that user chooses custom; When position candidate do not meet user choose custom time, the 8th numerical value is defined as user select be accustomed to the 5th sub-score, the 7th numerical value is less than the 8th numerical value.
In step 205, when evaluation factor has one, the sub-score of the evaluation factor calculated is defined as the score of position candidate.
The evaluation factor got when terminal only has one, then the sub-score of this evaluation factor calculated directly can be defined as the score of position candidate by terminal.
In step 206, when evaluation factor has two or more, according to the sub-score of each evaluation factor and the score of each self-corresponding weight calculation position candidate.
And if the evaluation factor that terminal gets has two or more, then terminal can calculate the sub-score of each evaluation factor and the weighted sum of each self-corresponding weight, by the score of the weighted sum that calculates alternatively position.
If the sub of each evaluation factor of position candidate must be divided into D
i, i be more than or equal to 1 integer, the weight corresponding to each sub-score is W
i;
The score P of position candidate is: P=D
i* W
i.
In the present embodiment, the value of the weight of each evaluation factor is not limited, and according to different user demands, the weight of each evaluation factor can be identical or different.
In step 207, position candidate the highest for score at least two position candidate is defined as cursor position.
After terminal calculates the score of each position candidate, position candidate the highest for score can be defined as cursor position by terminal.
In sum, the cursor position defining method provided in disclosure embodiment, by when receiving touch signal, at least two position candidate are determined in touch area corresponding to touch signal, obtain the evaluation factor of each position candidate, calculate the score of each position candidate according to the evaluation factor got, and then position candidate the highest for score at least two position candidate is defined as cursor position; Solve the problem that the accuracy rate of the cursor position that terminal in correlation technique is determined is lower; Reach and can mark to each position candidate according to the evaluation factor of each position candidate, position candidate the highest for score is defined as cursor position, and then reach the effect of the accuracy rate improving the cursor position determined.
The present embodiment is when evaluation factor has two or more, according to the sub-score of evaluation factor and the PTS of each self-corresponding weight calculation position candidate, make deviser can adjust the weight of each evaluation factor according to different user demands, and then make the cursor position finally determined more meet the user demand of user, improve the accuracy of the cursor position determined.
