Embodiment
Below with reference to accompanying drawings of the present invention each is preferred embodiment described.There is provided the description referring to accompanying drawing, to help the understanding to the example embodiment of the present invention limited by claim and equivalent thereof.It comprises the various details helping to understand, but they can only be counted as exemplary.Therefore, those skilled in the art will recognize that, can make various changes and modifications embodiment described herein, and do not depart from the scope of the present invention and spirit.And, in order to make instructions clearly succinct, will the detailed description to well known function and structure be omitted.
First, with reference to Fig. 1, the information processing method according to the embodiment of the present invention is described.As shown in Figure 1, described method comprises the steps.
First, in step S101, display character prompt set of regions.Wherein, described character prompt set of regions comprises the character prompt region of M non-overlapping copies, corresponding with M character respectively.Described character prompt set of regions is the set in the prompting region of corresponding relation for the touch location and character of pointing out user's touch operation.User, by the character prompt set of regions shown by viewing, can understand the position of the roughly input area of each character.Fig. 2 shows a kind of possible example of character prompt set of regions.Such as, suppose that user expects input character " A ", and recognized by the described character prompt set of regions of viewing, prompting region corresponding with character " A " in described character prompt set of regions is in the position of the side that keeps left, and so user can touch correspondence position substantially exactly when not seeing character prompt region.Certainly, user also can touch correspondence position to entirely accurate when watching character prompt region.Generally speaking, character prompt set of regions is standardized layout, and therefore, the principle of the design in character prompt region is neat, unified, attractive in appearance.Further, most of user knows for the Shi Fei Changshu, prompting region corresponding to character each in character prompt set of regions.
Then, in step S102, detect at least one touch operation.
Next, process proceeds to step S103.In step S103, based on character recognition set of regions, identify described at least one character corresponding at least one touch operation.Wherein, described character recognition set of regions comprises the character recognition region of M non-overlapping copies, corresponding with M character respectively.It should be noted that character recognition set of regions does not show.Different from character prompt set of regions, the principle of design in character recognition region considers user's finger and hand sizes, input habit, great majority point can be dropped in the character range that will input, and its distribution is not regular, varies, layout neither be neat.Fig. 3 shows a kind of possible example of character recognition set of regions.
In input process, user carries out in the prompting region corresponding to character each in character prompt set of regions the character that touch operation is expected to input user, but in identifying, not according to the prompting region in described character prompt set of regions corresponding to each character, but carry out the identification of character according to the identified region that each character in described character recognition set of regions is corresponding.
Here, it is pointed out that in M character, at least there is a region and do not mate character, the character prompt region that character is not mated corresponding in described region is different with character recognition region.In fact, under many circumstances, the character prompt region of each character in M character is different with character recognition region.
Certainly, because user needs to input according to character prompt region, therefore herein indication " difference " and non-fully is different, but only there is small difference, and there is common overlapping region larger compared with diff area in the character prompt region of same character and character recognition region usually.That is, character recognition region is only the more personalized region obtained by carrying out finely tuning according to the difference of different user on standardized character prompt region base, the amendment in essence not to character prompt region.
By using the character recognition region different from character prompt region, more can be adapted to the individual difference of different user, reduce the possibility of false triggering, improve the accuracy of input, help user not have when physical standard position, to realize touch system input at on-screen keyboard.
Character recognition region can immobilize after a birth, but as preferred embodiment, character recognition region constantly dynamically can adjust along with the input of user, thus the current state of the user that can fit more exactly and use habit.
Specifically, as preferred embodiment, as shown in Figure 4, after the step identifying at least one character corresponding at least one touch operation described, described method may further include:
In step S401, judge whether first predetermined condition.
If judge first predetermined condition in step S401, then process proceeds to step S402.In step S402, at least adjust the character recognition region of a character.
On the other hand, if judge not first predetermined condition in step S401, then process turns back to step S102, to carry out input operation next time.That is, character recognition region is not adjusted, and it is constant to maintain existing character recognition region.
Next, will the embodiment judging whether to adjust character recognition region and how to adjust character recognition region be described.
First, as the first embodiment, as shown in Figure 5, after the step identifying at least one character corresponding at least one touch operation described, described method comprises further:
In step S501, judge whether to identify termination character.Be input as example with English, when input completes a word, will space bar be inputted.Therefore, exemplarily, termination character can be space bar.Certainly, the present invention is not limited to this.Here termination character is intended to represent completing of single input, and therefore the example of any other possible termination character is also possible, and should be within the scope of the present invention.Further, it is pointed out that in this manual, is that boundary defines an input operation with termination character.The result of an input operation should be thought in the one or more characters inputted between two termination characters.As long as unidentified go out termination character, just think that this input operation does not terminate.
If when step S501 judges that the character identified corresponding to a touch operation is termination character, then suspend and identify described at least one character corresponding at least one touch operation, and process proceeds to step S502.In step S502, using at least one character described in before described termination character as a string processing.
On the other hand, if step S501 judge unidentified go out termination character, then process turn back to step S103 with continues identification touch operation corresponding to character.
After step S502, process proceeds to step S503.In step S503, according to the comparing of this character string that character library input with reality, determine error character and prediction expectation character.
Then, process proceeds to above described step S401.That is, judge whether that the step of first predetermined condition is carried out based on the determination result of described error character and described expectation character.
Such as, described first predetermined condition is that deviation between described error character and described expectation character is less than first threshold.
For the ease of understanding, for example, as a kind of situation, when user inputs word " fpx ", by this character string and character library comparative analysis being inferred the word that user expects to input should be " fox ".Therefore in this character string, error character is " p ", and expects that character is " o ".Due in character prompt region, character " p " is adjacent with character " o ", and in other words, deviation is therebetween very little.Thus can assert, user is the input error because false touch causes.In this case, may be position skew due to user's palm or the false touch that causes of use habit.Therefore, now need adjustment character recognition region to adapt to the current palm position of user or use habit to improve input accuracy.
But, as another kind of situation, when user inputs word " fcx ", similarly, by this character string and character library comparative analysis being inferred the word that user expects to input should be " fox ".Therefore in this character string, error character is " c ", and expects that character is " o ".But different from the situation of above described " fpx ", in character prompt region, character " c " is very far away with the distance of character " o ", and in other words, deviation is therebetween very large.Thus, can assert, the input error that user causes not due to false touch.In this case, user expects to input " fcx ".Therefore, now do not need to adjust character recognition region.
If judge first predetermined condition in step S401, namely need to adjust character recognition region, then process proceeds to step S402.In step S402, at least adjust the character recognition region of a character.
In this case, the step at least adjusting the character recognition region of a character comprises:
In step S4021, based on the deviation between described error character and described expectation character, determine the adjustment parameter of the identified region of described expectation character.Such as, adjust parameter and can comprise adjustment direction and adjustment amount.
Next, in step S4022, adjust with the character recognition region of described adjustment parameter to described expectation character.
The touch location of the touch operation wherein before adjustment corresponding to described error character is arranged in the identified region of described error character, and the touch location of touch operation after the adjustment corresponding to error character is arranged in the identified region of described expectation character.
In above adjustment process, adjustment expects that the character recognition region of character is with the touch location making it comprise the touch operation corresponding to error character.Certainly, based on principle of relativity, the character recognition region of error character also can be adjusted with the touch location making it not comprise the touch operation corresponding to error character.Further, in the above description, only the character recognition region of character or error character is expected in adjustment.But, when causing false touch in the skew due to user's palm, although the skew adjusting to adapt to user's palm has been carried out in the expectation character identified current or the character recognition region of error character, and the character recognition region of other characters in this palm overlay area caused due to this skew also very likely needs adjustment in ensuing input operation.Therefore, as preferred embodiment, can also jointly regulate by large regions.
Specifically, described character recognition set of regions is split into multiple subregion, and each in described multiple subregion includes the identified region of at least one character.Such as, character recognition set of regions can be divided into left hand subregion and right hand subregion.Further, in this case, after step S4022, the step at least adjusting the identified region of a character may further include:
In step S4023, judge which subregion described expectation character belongs to.
Then, in step S4024, with the adjustment parameter of the identified region of described expectation character, adjust the identified region of other characters in subregion belonging to described expectation character uniformly.
Secondly, as the second embodiment, as shown in Figure 7, after the step identifying at least one character corresponding at least one touch operation described, described method comprises further:
In step S701, judge whether to identify backspace character.
If judge that the character identified corresponding to a touch operation is backspace character in step S701, then process proceeds to step S702.In step S702, the character inputted before determining backspace character is error character, and the character inputted after backspace character is for expecting character.That is, user deletes this character fast and re-enters another character after input one character.So now, deleted character should think error character, and the character re-entered should be thought to expect character.
Then, process proceeds to above described step S401.That is, judge whether that the step of first predetermined condition is carried out based on the determination result of described error character and described expectation character.Similarly, such as, described first predetermined condition is that deviation between described error character and described expectation character is less than first threshold.
If judge first predetermined condition in step S401, namely need to adjust character recognition region, then process proceeds to step S402.In step S402, at least adjust the identified region of a character.
Similar with the first embodiment, the step wherein at least adjusting the identified region of a character comprises:
In step S4021, based on the deviation between described error character and described expectation character, determine the adjustment parameter of the identified region of described expectation character.Such as, adjust parameter and can comprise adjustment direction and adjustment amount.
Next, in step S4022, adjust with the identified region of described adjustment parameter to described expectation character.
The touch location of the touch operation wherein before adjustment corresponding to described error character is arranged in the identified region of described error character, and the touch location of touch operation after the adjustment corresponding to error character is arranged in the identified region of described expectation character.
Certainly, similar with the first embodiment, character recognition region adjustment here also can regulate by large regions jointly.
As the 3rd embodiment, as shown in Figure 8, at least adjust a character identified region step or after maintaining the constant step of existing identified region, and on carrying out once before touch operation, to comprise further:
In step S801, store the touch location in the identified region corresponding to each character.
Then, in step S802, judge whether second predetermined condition.Such as, the second predetermined condition can be stored the touch location in the identified region corresponding to character of predetermined quantity.And for example, the second predetermined condition also can be have passed through predetermined amount of time.
If be yes in the judged result of step S802, then process proceeds to step S803.In step S803, for each in M character, calculate the mean place of all touch locations in the identified region of its correspondence.Then, process proceeds to step S804.In step S804, using each mean place as the unique point of the identified region of the character of its correspondence, optimize described character recognition set of regions further.Such as, the generation for the character recognition region of a character can be carried out in the following manner: in the identified region of this character all touch locations mean place and be adjacent character identified region in the perpendicular bisector of line of mean place of all touch locations generate character recognition region as the border in the character recognition region of this character.
On the other hand, if be no in the judged result of step S802, namely not yet accumulate enough statisticss, then process turns back to step S102, to carry out input operation next time.
By the large data statistics in the 3rd embodiment, the character recognition set of regions after optimizing can be made more to approach the use habit of user.
Certainly, here large data statistics can hereinbefore shown in the first embodiment and the second embodiment adjustment after perform as further Optimization Steps, or the adjustment of the first embodiment shown in also can replacing hereinbefore and the second embodiment, performs as independent set-up procedure.
In addition, as preferred embodiment, before the step detecting at least one touch operation, described method can further include: detect original reference position in described character prompt set of regions and whether described operating body meets predetermined location relationship; If testing result is no, then display please adjust the information of operating body position.If testing result is yes, then carry out above described ensuing process.By such detection in advance, can guarantee that the initial position of operating body is accurately, thus the accuracy rate of input after can guaranteeing.If just there is skew in the initial position of operating body, the input so must accuracy rate very low.
Such as, when input mechanism is that (namely finger can be put on the touchscreen for a long time in pressure input, now can not trigger, only just can input when pointing pressing with strength) time, detecting original reference position in described character prompt set of regions and described operating body, whether to meet predetermined location relationship can be detect in described original reference position whether there is operating body.
And for example, when input mechanism is traditional touch input (as long as namely finger touch will input), detecting original reference position in described character prompt set of regions and described operating body, whether to meet predetermined location relationship can be detect above described original reference position whether there is operating body within predetermined distance range, and namely unsettled (hover) detects.
In addition, after character recognition set of regions is repeatedly adjusted, the situation that itself and character prompt set of regions have a long way to go may be there is.Now, need to calibrate.Specifically, described method also comprises the steps: to calculate the distance between the prompting region corresponding to each character in described character prompt set of regions and the identified region corresponding to this character in described character recognition set of regions further; Then, judge whether this distance is greater than Second Threshold; If so, then display please adjust the information of operating body position, and carries out initialization to described character recognition set of regions.Such as, by carrying out initialization to character recognition set of regions as follows, can namely regenerate character recognition set of regions: using the central point in the character prompt region of each character and be adjacent character character prompt regional center point line perpendicular bisector as the character recognition region of this character border generate character recognition region.
The information processing method according to the embodiment of the present invention is described in detail above referring to figs. 1 through Fig. 8.
Next, with reference to Fig. 9, the messaging device according to the embodiment of the present invention is described.As shown in Figure 9, messaging device 900 comprises: display device 901, first pick-up unit 902 and recognition device 903.

Recognition device 903 is for based on character recognition set of regions, and identify described at least one character corresponding at least one touch operation, described character recognition set of regions comprises the character recognition region of M non-overlapping copies, corresponding with M character respectively.
Wherein, in M character, at least there is a region and do not mate character, the character prompt region that character is not mated corresponding in described region is different with character recognition region.
By using the character recognition region different from character prompt region, more can be adapted to the individual difference of different user, reduce the possibility of false triggering, improve the accuracy of input, help user not have when physical standard position, to realize touch system input at on-screen keyboard.
Character recognition region can immobilize after a birth, but as preferred embodiment, character recognition region constantly dynamically can adjust along with the input of user, thus the current state of the user that can fit more exactly and use habit.
Specifically, as preferred embodiment, as shown in Figure 10, equipment 900 may further include: the first judgment means 1001, for after at least one character described in described recognition unit identification corresponding at least one touch operation, judge whether first predetermined condition; And adjusting gear 1002, if judge first predetermined condition for described first judgment means 1001, then at least adjust the identified region of a character; If described first judgment means 1001 judges not first predetermined condition, then maintain existing identified region constant.
Next, will the embodiment judging whether to adjust character recognition region and how to adjust character recognition region be described.
First, as the first embodiment, when identifying the character corresponding to a touch operation and being termination character, described recognition device 903 suspends identifying operation, and using at least one character described in before described termination character as a string processing.
Further, as shown in figure 11, described equipment 900 comprises further: determining device 1101, for the comparing of this character string input with reality according to character library, determines error character and prediction expectation character.
Wherein said first judgment means 1001 based on described error character and described expectation character determination result and judge whether first predetermined condition.As noted before, such as, described first predetermined condition is that the deviation between described error character and described expectation character is less than first threshold.
