The invention provides a kind of characters input method of mobile terminal, as shown in Figure 1, described method step comprises:
The input instruction of S1, reception user, opens full keyboard inputting interface.
First after mobile terminal receives the input instruction of user, the inputting interface of full keyboard is demonstrated in display screen, i.e. these 26 letters of A-Z all one_to_one corresponding touch areas, the touch point of user is positioned at the region at which letter, then what explanation user selected input is that letter.After mobile terminal opens described full keyboard inputting interface, wait for the instruction of the selected input character of user.
Concrete, as shown in Figure 2, each letter all occupies certain touch area unit, such as, be the lattice coordinates XOY of touch-screen in fig. 2, wherein rectangle A1A2A3A4 is the touch area unit of alphabetical A, the point (x, y) touched on screen as user meets formula:
XA4<x<xA2 and yA4<y<yA2 formula (1)
Wherein, xA2 is A2 point X-axis coordinate figure, and yA2 is A2 point Y-axis coordinate figure; XA4 is A4 point X-axis coordinate figure, and yA4 is A4 point Y-axis coordinate figure.
Shi Ze thinks that user has touched rectangle A1A2A3A4 place unit, and other 25 alphabetical territory element methods to set up are similar; As rectangle B1B2B3B4 be the touch area unit of letter b, rectangle M1M2M3M4 is the touch area unit of alphabetical M, etc.;
It should be noted that the overlap that not have between the touch area unit shared by each letter.
Character on S2, the inputting interface of acquisition corresponding to user touch point, obtains in the character combination corresponding to this character simultaneously and inputs N number of character that number of times is arranged in top N.
While user carrys out the selected character that it will input by touch area, the alphabetical place unit that touch shows on the touchscreen, as shown in Figure 3, this records in mobile terminal will be there is in the below of this letter, put in order according to the height of this monogram occurrence number, the monogram that this letter arranged out and other monograms are formed, user can by selecting next letter from this monogram.Namely in this input keyboard, containing two-layer up and down, wherein superstructure comprises this touch area corresponding to 26 letters of A-Z, and these 26 alphabetical belows, all to there being its understructure, i.e. the monogram of this letter and other alphabetical combined formation, in understructure, described monogram carries out arranging according to the height of the combination number of times of its record, if identical, then arranges according to 26 alphabetical putting in order.
And the letter be arranged in described monogram while of in this step, also in top N.Described N value can be arranged by User Defined, such as: be set to 3.
S3, by obtain character and described in be arranged in top N N number of character in full keyboard inputting interface, amplify display.
The character being arranged in top N in letter corresponding to user-selected fixed character and the below character combination of this letter is carried out amplification display, thus facilitates user to select.
In order to improve the efficiency of user inputs character, also comprise in this step:
S31, by obtain character and described in be arranged in top N N number of character carry out amplifications display while, according to the sequence with this character combination number of times, the combination of this character and other characters is shown.
S32, judge whether described character and the viewing area of described N number of character in full keyboard inputting interface overlap with the viewing area of other characters, if overlap, then putting in order according to full keyboard inputting interface, by described lap adjustment separately.
As shown in Figure 4, the touch area unit at alphabetical place user selected amplifies display.Concrete, amplification display can be carried out according to the multiple that user is predetermined, or system default multiple amplifies display.As the lattice coordinates XOY that Fig. 4 is touch-screen, wherein rectangle A1'A2'A3'A4' is the touch area unit after adjusting the touch unit of alphabetical A, then think that when the point (x, y) that user touches on screen meets formula (2) user has touched rectangle A1'A2'A3'A4' place unit:
XA4'<x<xA2' and yA4'<y<yA2' formula (2)
Wherein, xA2' is A2' point X-axis coordinate figure, and yA2' is A2' point Y-axis coordinate figure; XA4' is A4' point X-axis coordinate figure, and yA4' is A4' point Y-axis coordinate figure.
Method to set up after other 25 touch area unit amplify is similar.
Rectangle A1A2A3A4 before rectangle A1'A2'A3'A4' after the touch unit adjustment of letter A and the touch unit of alphabetical A adjust meets formula:
XA2'=xA2+ (xA2-xA1) * (rz-1)/2 formula (3)
YA2'=yA2+ (yA2-yA3) * (rz-1)/2 formula (4)
XA4'=xA4-(xA3-xA4) * (rz-1)/2 formula (5)
YA4'=yA4-(yA1-yA2) * (rz-1)/2 formula (6)
In formula (3), (4), (5), (6), rz is amplification coefficient, rz>1, be used for representing that the rectangle A1'A2'A3'A4' after the touch unit adjustment of alphabetical A is the multiple that the rectangle A1A2A3A4 before the touch unit adjustment of alphabetical A amplifies, such as rz is 2; Other 25 unit adjust the touch area unit class of forward and backward method to set up and alphabetical A seemingly.
Because the letter user selected and assembled arrangement other letters preceding thereof amplify display, then in input method display interface, the phenomenon of touch area overlap may be there is, then overlapping in order to avoid touch area, touch-screen cannot normally identify the letter that user selects, then also comprise in this step, zone adjusting unit, for according to 26 alphabetical putting in order, input method viewing area after amplifying display is carried out readjusting rear display, avoids the phenomenon of alphabetical touch area overlap to occur.
Described method also comprises:
S4, when after the character input that user's touch point is corresponding, then control the region that described character and described N number of character show in full keyboard inputting interface, reduce according to the inverse of the multiple amplified in advance.
Selection for the ease of character late inputs, and after input selected in character, then the automatic inverse according to original enlargement factor, at the character will amplified in step S3, reduces back original state.As shown in Figure 5, the touch unit of alphabetical A reduce after rectangle A1''A2''A3''A4'' and the touch area unit of alphabetical A adjust before rectangle A1A2A3A4 meet formula:
XA2''=xA2-(xA2-xA1) * (1-rs)/2 formula (8)
YA2''=yA2-(yA2-yA3) * (1-rs)/2 formula (9)
XA4''=xA4+ (xA3-xA4) * (1-rs)/2 formula (10)
YA4''=yA4+ (yA1-yA2) * (1-rs)/2 formula (11)
In formula (8), (9), (10), (11), rs is coefficient of reduction, rs<1, be used for representing the touch unit of alphabetical A reduce after rectangle A1''A2''A3''A4'' be the multiple that the rectangle A1A2A3A4 before the touch area unit adjustment of alphabetical A reduces, such as rs is 0.5, and demand fulfillment formula:
rs*rz＝1
Described step S4 also comprises:
S41, in the upper character combination once corresponding to character of user's input, the input number of times that character of this input of user and the character combination of last input character record is added 1.
After each monogram has inputted, then automatic described monogram is added 1, provide convenient for inputting this monogram next time.
Concrete, after touch area unit receives the touch instruction of user, in adjustment form superstructure, first find the element of the letter correspondence that this touch area unit is corresponding, the variable corresponding to letter finding this touch area corresponding in the understructure of the touch instruction again receiving user when touch area unit then under this element, adds 1 by this variable.Such as, in spelling input method, input zhang,
When inputting zh, then the combination number of times of corresponding under z letter monogram zh adds 1;
When inputting zha, then the combination number of times of corresponding under h letter monogram ha adds 1;
When inputting zhan, then the combination number of times of corresponding under a letter monogram an adds 1;
