ZP times of original display interface size is contracted to, referring to Fig. 8, another screen display interface contracting that Fig. 8 provides for the present embodiment
Schematic diagram after putting；
When user to the touch point of screen is B when, for hand is small and user of right-handed operation, screen is used after reducing
Family is easier to touch B, without using bimanualness, for the big user of hand, need not bent finger manipulation, use after screen magnifying
Family experience is more preferable；By such scheme, the fixed point of screen display interface scaling is determined to the touch point of screen by user, is realized
The personalization of screen display interface zoom direction.
The scheme provided using the present embodiment, is zoomed in and out using fingerprint texture distance value to the display interface of screen, with
The practical operation situation of user is adapted to, the probability of user misoperation is reduced, improves Consumer's Experience；
Further, the personalization of the standard value of fingerprint texture distance value is realized, is proposed not for different user colony
The standard value SD of same fingerprint texture distance value, can be adapted to different user groups；
Further, the personalization of screen scaling ratio is realized, the fingerprint texture distance value by calculating user is proposed
With the standard value SD of fingerprint texture distance value ratio, to react user's one-handed performance scope, rather than by the prior art
Finger touch scope and determine user's one-handed performance scope, it is so more accurate；
Further, the fixed point of screen display interface scaling is determined to the touch point of screen by user, screen is realized
The personalization of display interface zoom direction.

3rd embodiment
A kind of Zoom method of screen display interface is present embodiments provided, is provided referring to Figure 10, Figure 10 for the present embodiment
A kind of screen display interface Zoom method flow chart, this method comprises the following steps：
S1001：Gather finger print information；
Optionally, before S1001, in addition to：
The default interface of display, the default interface includes the options of multiple default fingerprint texture distance values；Different is pre-
If fingerprint texture distance value be configured according to different customer groups；
Fingerprint texture distance value is the size of the distance between fingerprint texture.Everyone fingerprint is different, fingerprint texture it
Between distance it is also different, the distance of fingerprint texture can react the finger length of a people to a certain extent, and texture is got over
Greatly, finger is longer, and the scope that finger is touched is also bigger, otherwise smaller；Length with touching scope decision-making finger by finger in the past
Degree is compared, more accurately, because user touches screen ranges because time, mode are different, is differed；
Exemplary, default fingerprint texture distance value can be obtained in the following manner：Cell phone manufacturer is adopted by data
Collection, analysis, draw the standard value of public users fingerprint texture distance value, are designated as SD, different user colony, SD value differs
Sample, for example, can be divided into the SD, the SD of male's fingerprint texture distance value, women fingerprint texture distance of children's fingerprint texture distance value
SD of value etc.；By such scheme, the personalization of the standard value of fingerprint texture distance value is realized, colony carries for different user
Go out the standard value SD of different fingerprint texture distance values, different user groups can be adapted to；
Receive selected operation of the user to the options of one of them default fingerprint texture distance value；
Required default fingerprint texture distance value is determined according to the selected operation of user；
, can also be according to hand in addition to above-mentioned preset multiple default fingerprint texture distance values are selected for user
The terminals such as machine towards main users colony, the SD of a fingerprint texture distance value is pre-set in the terminals such as mobile phone, for example
The main users colony of Mobile phone be women, then in this mobile phone preset women fingerprint texture distance value SD.
Optionally, this method also includes：
The default interface of display first, the first default interface includes the choosing of the opening and closing of screen display interface zoom function
Select item；
When receiving user to the selected operation of the unlatching options of screen display interface zoom function, then screen is opened
The zoom function of display interface, the step of subsequently into S1001；
Optionally, after selected operation of the user to the unlatching options of screen display interface zoom function is received,
Before S1001, in addition to：
The default interface of display second, the second default interface includes the options of multiple applications；
Receive selected operation of the user at least one options；
The screen display interface zoom function of correspondence application is opened according to the selected operation of user；
Or, analysis user is accustomed to the historical operation of application；Screen is opened into the application that access times exceed given threshold
Curtain display interface zoom function；Screen display interface zoom function is opened in the application that can user be commonly used.
When receiving user to the selected operation of the closing options of screen display interface zoom function, then screen is closed
The function of display interface scaling.
S1002：Calculate the fingerprint texture distance value of finger print information；
After the finger print information of user's typing is collected, the fingerprint texture distance value of the finger print information is calculated, UD is designated as；
Referring to Fig. 4, Fig. 4 is that a kind of fingerprint texture that the present embodiment is provided is taken from using in the schematic diagram chosen, Fig. 4
The fingerprint of family difference finger, user oneself decision-making calculates the number of fingerprint, if n fingerprint of user's typing, each fingerprint texture
Distance value takes the texture value UD (i) as the fingerprint that two pixels are most clear, vertical range is nearest, and the UD of user can be with
Calculate in the following ways：UD is equal to UD (1), UD (2), UD (3) ... UD (n) sums and n ratios.
S1003：Fingerprint texture distance value is compared with default fingerprint texture distance value；
S1004：The display interface of screen is zoomed in and out according to comparative result；
Wherein, S1004 includes：
When fingerprint texture distance value is more than default fingerprint texture distance value, the display interface of screen is amplified,
And multiplication factor is：The ratio of fingerprint texture distance value and default fingerprint texture distance value；
When fingerprint texture distance value is less than default fingerprint texture distance value, the display interface of screen is reduced,
And minification is：The ratio of fingerprint texture distance value and default fingerprint texture distance value；That is, obtaining user fingerprints letter
After the UD of breath, the scaling of screen display interface is calculated, ZP is designated as, ZP is equal to UD and SD ratio, if ZP>1, then will screen
Curtain display interface is amplified to ZP times of original display interface, if ZP<1, then screen display interface is contracted to original display circle
ZP times of face；By such scheme, realize the personalization of screen scaling ratio, propose by calculate the fingerprint texture of user away from
From value and the standard value SD of fingerprint texture distance value ratio, to react user's one-handed performance scope, rather than pass through existing skill
Finger in art touches scope to determine user's one-handed performance scope, so more accurate.
Wherein, during being zoomed in and out to the display interface of screen, in addition to：
Detect touch point of the user to screen；
Using touch point as fixed point, the display interface of screen is scaled.
