201: show acquiescence.
In the present embodiment, this step 201 is the firsts that show the dummy keyboard of corresponding described show percent according to the show percent that sets in advance on touch-screen.
Wherein, can determine the area of dummy keyboard earlier according to the area of show percent that sets in advance and the keyboard viewing area on the touch-screen, the keyboard viewing area on described touch-screen shows the first of described dummy keyboard again.
Wherein, show percent is the number percent of the displayable dummy keyboard in dummy keyboard viewing area on the touch-screen, in the present embodiment, can set in advance several show percents, for example, it is 25% that show percent can be set, promptly show 1/4 dummy keyboard, as shown in Figure 3A; 50%, promptly show 1/2 dummy keyboard, shown in Fig. 3 B; 75%, promptly show 3/4 dummy keyboard, shown in Fig. 3 C; With 100%, promptly show whole dummy keyboards, shown in Fig. 3 D.Fix owing to be used to show the area in the zone of dummy keyboard on the touch-screen, when show percent more hour, the area of corresponding virtual keyboard is big more.For example, the area of supposing the dummy keyboard viewing area on the touch-screen is S, if show percent is 25%, then the area of the dummy keyboard under this show percent is S/ (25%)=4S, the part dummy keyboard that is presented at the dummy keyboard viewing area on the touch-screen be area be 4S dummy keyboard 25%; And if show percent is 75%, then the area of the dummy keyboard under this show percent is S/ (75%)=(4/3) S, less than show percent is the area of 25% o'clock corresponding virtual keyboard, and then the area that takies of each key of the dummy keyboard that shows of dummy keyboard viewing area also reduces thereupon.
In the present embodiment, do not limit any part that shows dummy keyboard, for example, when show percent is 25%, do not limit show dummy keyboard which 1/4, can be leftmost, also can be rightmost, or near center section.
In the present embodiment, by setting in advance several show percents, so that on limited touch-screen, show the dummy keyboard of different weight percentage, so, then can amplify dummy keyboard by reducing show percent, increasing the area that each button takies, the excessive and problem of too small mistake input that causes of button or mistake identification of the finger tripe of having avoided user's finger.
202: refer to tripe identification.
In the present embodiment, this step 202 is finger tripe sizes of identification user finger, adjusts described show percent according to described finger tripe size.
In the present embodiment, can discern the finger tripe size of user's finger by camera induction or modes such as laser induced or infrared induction, so that when the button area of each button of the dummy keyboard of the area of the finger tripe of user finger and current demonstration does not match, by adjusting show percent, adjust the area of dummy keyboard, change the area of each button of the dummy keyboard of demonstration.
Wherein, the recognition technology that employing camera/laser/modes such as infrared induction are carried out object area size identification is comparatively ripe in the prior art, does not repeat them here.
In the present embodiment, can the threshold range of the area of each button be set, so that the usefulness that compares with the area of the finger tripe of user finger at the area of the dummy keyboard under each show percent.
An embodiment according to present embodiment, if the finger tripe area that the user who identifies by above-mentioned induction technology points then is adjusted into the show percent that sets in advance less than described with described show percent greater than the upper limit of the threshold range of the area of each button of the pairing dummy keyboard of show percent that sets in advance.
Another one embodiment according to present embodiment, if the finger tripe area that the user who identifies by above-mentioned induction technology points then is adjusted into the show percent that sets in advance greater than described with described show percent less than the lower limit of the threshold range of the area of each button of the described pairing dummy keyboard of show percent that sets in advance.
Another one embodiment according to present embodiment, if the finger tripe area of the user who identifies by above-mentioned induction technology finger is positioned at the threshold range of area of each button of the described pairing dummy keyboard of show percent that sets in advance, then with the described show percent that sets in advance as adjusted show percent.
203: refresh demonstration.
In the present embodiment, this step 203 is the firsts that show the dummy keyboard of corresponding described adjusted show percent according to described adjusted show percent on the touch-screen of mobile device.
In the present embodiment, identical with step 201, also can determine the area of adjusted dummy keyboard earlier according to the area of the keyboard viewing area on described adjusted show percent and the touch-screen, the keyboard viewing area on described touch-screen shows the first of described adjusted dummy keyboard again.
In the present embodiment, owing to adjusted show percent, therefore the area of corresponding virtual keyboard is also adjusted, after the adjustment, the area of each button that is presented at the dummy keyboard of the dummy keyboard viewing area on the touch-screen can adapt to the area of the finger tripe of user's finger, excessive and the problem of too small mistake input that causes of button or mistake identification of the finger tripe of having avoided user's finger, the perhaps too small and problem of the excessive demonstration wasting of resources that causes of button of the finger tripe of user's finger.
