Fig. 2 is the process flow diagram of the input method 200 for dummy keyboard schematically illustrated according to the embodiment of the present application.This input method 200 can be applicable to electronic equipment as shown in Figure 1, and this electronic equipment comprises touch-screen, and described touch-screen at least comprises display module and touch sensible module.
As shown in Figure 2, described input method 200 can comprise: utilize display module display keyboard pattern on described touch-screen, and each character of this keyboard pattern is presented in the different viewing areas on described touch-screen (S210) respectively; Utilize according to pre-defined rule the zone of action that described touch sensible module installation is corresponding with the character of keyboard pattern respectively, wherein, the zone of action of at least one character is different from the viewing area of this at least one character (S220); Utilize described touch sensible module senses input operation touch location on the touchscreen (S230); Using the character corresponding with the zone of action at this touch location place as input character (S240).
In S210, utilize display module display keyboard pattern on described touch-screen.Such as, display keyboard pattern on the touchscreen when described touch-screen starting character input.The character of this keyboard pattern typically has similar distribution with each character in physical keyboard.As shown in Figure 1, the character of keyboard pattern can comprise letter, numeral, carriage return, space, punctuation mark etc., and each character is presented in the different viewing areas on described touch-screen respectively.Keep at a certain distance away between the viewing area of kinds of characters.
Typically, the viewing area that occupies on the touchscreen of each character is identical with the zone of action of this character.Namely being its viewing area for the square frame at the A in the keyboard pattern of alphabetical A, Fig. 1, is also its zone of action.When user wants input alphabet A, its input operation must touch its zone of action (i.e. viewing area).If input operation touches the zone of action of alphabetical A and the zone of action of adjacent alphabetical S, then alphabetical S may be defined as input character; If input operation touches the region between the edge of the zone of action of alphabetical A and alphabetical A and S, then may determine that described input operation is invalid.
In S220, utilize according to pre-defined rule the zone of action that described touch sensible module installation is corresponding with the character of keyboard pattern respectively, wherein, the zone of action of at least one character is different from the viewing area of this at least one character.The zone of action of the specific character of the keyboard pattern utilizing this S220 to arrange is conventionally not identical with the viewing area of this specific character, but the zone of action of specific character deviate from its viewing area and different.For described specific character for alphabetical A, the zone of action of alphabetical A can be greater than its viewing area, and the zone of action of alphabetical A can also offset relative to the direction of its viewing area to alphabetical S.The zone of action due to alphabetical A is different from its viewing area, even if so input operation touches the edge of the viewing area of alphabetical A, or input operation touches alphabetical A and alphabetical S, also input character can be defined as alphabetical A.
Each corresponding with the character of keyboard pattern respectively zone of action can be set according to pre-defined rule.In practice, can consider described input operation input each character time motor habit, user viewing angle characteristic etc. each corresponding with the character of keyboard pattern respectively zone of action is set.Composition graphs 3-6 specifically describes the setting of each zone of action below.
In S230, utilize described touch sensible module senses input operation touch location on the touchscreen.Various technology can be adopted to form described touch sensible module to sense the touch location of input operation.Such as, self-capacitance can be adopted to sense mode to sense the touch location of input operation, mutual capacitance can also be adopted to sense mode to sense the touch location of input operation, resistance sensing mode can also be adopted to sense the touch location of input operation.The mode of the touch location of concrete sensing input operation does not form the restriction to the embodiment of the present application.
In self-capacitance sensing mode, the charge storage capacity of the isolated conductor self arranged in touch-screen is utilized to come sensing touch position, in touch-screen, the electric field of the isolated conductor arranged is open, when have another conductor (such as point) with it close to time, privately owned electric field is just established between two conductors, just there is relative voltage, utilized this relative voltage can detect the touch location of input operation.In mutual capacitance sensing mode, transverse electrode and longitudinal electrode is made in touch-screen, the place that two arrays of electrodes intersects will form electric capacity, when finger touch is to touch-screen, have impact on the coupling between two electrodes near touch point, thus the electric capacity changed between these two electrodes, thus determine the touch location of input operation by the change detecting this electric capacity.In resistance-type sensing mode, the sensing of touch location is realized by pressure sensitive principle, when input operation contact touch-screen, the two conductive layers of original mutually insulated has just had a contact in position, touch point, this can change the resistance of the resistive surface of touch-screen, the resistance of this resistance is relevant to the position of touch point in touch-screen, thus by detecting described resistance to determine the touch location of input operation.
In S240, using the character corresponding with the zone of action at this touch location place as input character.Be provided with in S220 and the character of keyboard pattern each zone of action one to one, the touch location of input operation is determined in S230, thus can determine that the touch location of this input operation is positioned at the zone of action of which character, thus using the character corresponding with the zone of action at this touch location place as input character.
In ideal situation, with the character of keyboard pattern one to one each zone of action be independent of one another and nonoverlapping, input character can be determined uniquely like this in S240.But, owing to can consider the motor habit of input operation in S220, the viewing angle characteristic etc. of user arranges each corresponding with the character of keyboard pattern respectively zone of action, one to one may be partly overlapping between each zone of action with the character of keyboard pattern.When described touch location crosses over the zone of action of two characters, two words comprising these two characters can be obtained in this S240 from dictionary, determine the input character of this input operation according to the selection of user to described two words.That is, utilize dictionary to assist to judge the character that input operation will input, thus improve validity and the accuracy of input operation.
In the technical scheme of the input method for dummy keyboard of the embodiment of the present application, the viewing area being different from this at least one character is set to by the zone of action of at least one character by keyboard pattern, thus also effectively and confirm input character exactly, the experience of user can be improved when deviate from the viewing area of character in the touch area of input operation.
The mode arranging the zone of action in the input method 200 of Fig. 2 is described below in conjunction with Fig. 3 to Fig. 6.
Fig. 3 be schematically illustrate Fig. 2 for the process flow diagram arranging the first example of the zone of action (S220) in the input method 200 of dummy keyboard.As shown in Figure 3, describedly the described touch sensible module installation zone of action corresponding with the character of keyboard pattern is respectively utilized to comprise according to pre-defined rule: the zone of action model obtaining the character of described keyboard pattern, wherein, this zone of action model obtains according to history input information, and this history input information comprises the repeatedly input of each character and corresponding touch location (S221); According to described zone of action model, the zone of action (S222) corresponding with each character is respectively set.
In S221, such as, the history of various algorithm or this character of theoretical analysis can be utilized to input information to obtain the zone of action model of the character of described keyboard pattern.Such as, the input operation for alphabetical A repeatedly can be performed in advance, record the touch area of this repeatedly input operation, statistical study is carried out to the recorded touch area to alphabetical A and obtains the probability distribution of the touch area to alphabetical A, using the zone of action model of the probability distribution of the touch area of obtained alphabetical A as alphabetical A.Similar mode can be taked to obtain the zone of action model of other character of keyboard pattern.The concrete mode obtaining the zone of action model of the character of described keyboard pattern does not form the restriction to the embodiment of the present application.
In S222, for specific character, such as can using the probability distribution of the touch area of specific character higher than the touch area of predetermined value as the zone of action of this specific character, thus be provided with the zone of action corresponding with this specific character respectively.For the described repeatedly input operation carried out in advance, can be tested by input operation and intensively obtain, or each input operation can be recorded in real time and the input information of the input operation of real time record is used for obtaining described zone of action model.
Fig. 4 schematically illustrates the zone of action utilized on the keyboard pattern set by the mode arranging the zone of action of Fig. 3.In the diagram, profit illustrate with dashed lines the zone of action of the space symbol on keyboard pattern, alphabetical A, alphabetical S.As shown in Figure 4, the zone of action of space symbol is greater than its viewing area, and particularly in the below of this space symbol, this is such as because to the touch area of the input operation of space symbol usually at the lower edge of shown space symbol; The zone of action of letter A is greater than its viewing area, and particularly on the right side of this alphabetical A, this is such as because alphabetical A is in the middle section that the left side of keyboard pattern and input operation are more prone to keyboard pattern; The zone of action of letter S is greater than its viewing area, and the left and right sides of the zone of action of alphabetical S all exceeds its viewing area, and this is such as because the less zone of action of input operation that causes of display area of alphabetical S is inevitably overlapping with adjacent character.
Arranging in the process of the zone of action of the character of keyboard pattern as shown in Figure 3, it is also conceivable to different users or dissimilar electronic equipment to arrange the different zone of action corresponding with character that is keyboard pattern.Such as, when obtaining the zone of action model of the character of described keyboard pattern in S221, the zone of action model of specific user to each character of described keyboard pattern can be obtained, that is distinguish different users and different zone of action models is set up to different users; When determining the zone of action corresponding with each character respectively according to described zone of action model in S222, can determine according to the zone of action model of described specific user the zone of action corresponding with each character being respectively applicable to this specific user.By arranging the different zone of action corresponding with character that is keyboard pattern for different users, validity and the accuracy of the input operation of user can be improved, thus promote the experience of user.
In addition, for different electronic equipments, the size of the keyboard pattern wherein shown may be different, correspondingly may affect the zone of action model of input operation, thus may determine the different zones of action corresponding from specific character for different electronic equipments.This also contributes to validity and the accuracy of the input operation improving user, thus improves the experience of user.
As shown in Figure 4, in the situation of the zone of action possibility overlap of kinds of characters, then touch location can be caused to cross over the zone of action of two characters.Now, two words comprising these two characters can be obtained from dictionary; Determine the input character of this input operation according to the selection of user to described two words, thus utilize dictionary to determine correct input character.
