The air line distance (not necessarily normal to screen) of display area that can be by eyes of user to button on the screen as currently away from
From.
S2：Current font parameter is obtained using current relevant parameter.
Current font parameter may include at least one of current font size, current type, current color of button font.
Button font refers to the display parameters of character in button, and the character in button can be text or icon.For text formatting
Button character, current font size can refer to its specific font size, such as 16sp, for the button character of iconic format, currently
Font size can refer to its specific size.Current type may include that the specific font of button character (is only applicable to text, such as black

As shown in Fig. 2, button font method of adjustment second embodiment of the present invention, is adjusted in the method for the present invention button font
On the basis of first embodiment, S2 includes：
S21：Current font parameter is calculated using current relevant parameter and constraint function.
Constraint function can be expressed as y=f (x), and wherein f is constraint function, and x is the independent variable of constraint function, and y is constraint
The dependent variable of function.The independent variable x of constraint function includes current relevant parameter, and the dependent variable y of constraint function includes current font
Parameter.For example, in the case that current relevant parameter includes current distance and current environment light intensity, current font parameter sc=f (dc,
lc), wherein dcFor current distance, lcFor current environment light intensity.
Constraint function is usually to pre-set and store in a memory in the mobile terminal.For example, can before manufacture
To carry out many experiments, the font parameter being suitble under different relevant parameters is acquired, so that it is determined that constraint function.It was using
Cheng Zhong, constraint function can be updated using current font parameter and current relevant parameter later by obtaining current font parameter.
Other than relevant parameter, the independent variable of constraint function may further include default font parameter and corresponding pre-
If relevant parameter.Before this, it can be searched in the mapping relations between pre-stored relevant parameter and font parameter default
Font parameter and its corresponding default relevant parameter.
In general, it can be selected in all relevant parameters that mapping relations include with current relevant parameter matching degree most
Relevant parameter is preset in high conduct.Matching degree highest means default global error between relevant parameter and current relevant parameter
It is minimum.The calculating of global error can use some or all of parameter in relevant parameter, in this course, relevant parameter
In different parameters can have different priority/weights.For example, in the case where relevant parameter includes key arrangement, press
Key layout can have highest priority/maximum weight.
For example, in one embodiment, the object of adjustment is the button font of entering method keyboard, and font parameter is only
Including font size.In the case that the entering method keyboard layout found in mapping relations is 9 key, it is 20sp to preset font size, corresponding
Pre-determined distance is 30cm, and it is 500 luxs to preset environmental light intensity.According to formula sc=sd+((dc-dd)*doffset/dstep)*
dweight+((ld-lc)*loffset/lstep)*(1-dweight) calculate current font size, wherein scFor current font size, sdTo preset font size,
dcFor pre-determined distance, ddFor current distance, doffsetThe offset changed with distance for font size；dstepChange for reference distance and walks
It is long, lcTo preset environmental light intensity, ldFor current environment light intensity, loffsetThe offset changed with environmental light intensity for font size；lstepFor
Reference environment light intensity change step.
In mapping relations, the value of the parameter in relevant parameter can be section, can also be isolated number.If worked as
Each parameter in preceding relevant parameter is equal with the corresponding parameter in default relevant parameter or falls into its section, then can save
Go the calculating process of constraint function and directly using default font parameter as current font parameter.
In other embodiments of the present invention, other modes may be used to obtain current font parameter, for example, basis respectively
Each parameter in current relevant parameter determines a corresponding candidate font parameter, then according to default rule, from all
One is selected in candidate font parameter as current font parameter, or comprehensive all candidate font parameters are calculated and (such as weighted
It is average) obtain current font parameter.

Face illustrates a kind of specific adjustment mode by taking font size as an example.As shown in figure 4, optional, this step can specifically include：
S221：Judge the ratio of current font size character boundary and current button size whether in threshold range.
By taking rectangular character and button as an example, the size of character and button is determined by its width and height.Behaviour can be called
Make the function of system to obtain the boundary up and down of character under third font size, the difference of right boundary is the width of character, up and down
The difference on boundary is the height of character.The ratio of width and height can separately be carried out when judging ratio whether in threshold range
Judge, directly the ratio of character and button size can also be judged.When width and height separately judge, width
Threshold range and the threshold range of height may be the same or different.
For the beauty of display, it can require character that cannot exceed button boundary, the upper limit of threshold range can be at this time
1。
If ratio not in threshold range, jumps to S222, otherwise current font size is not adjusted.
S222：Adjustment is zoomed in and out to current font size.
The ratio of current font size character boundary and current button size after scaling adjustment is in threshold range.
For example, then above entering method keyboard example, current font size s is calculatedcLater, call operation system
The function Paint of offer.Define Rect r=newPaint () .getTextBounds ().The input quantity of Paint functions is
s3, output quantity r includes r.left, r.right, r.top and r.bottom, respectively represents third font size s3Character it is left and right,
Upper and lower boundary.The width width=r.right-r.left of third font size character, height height=r.bottom-r.top.
The threshold range of width ratio and height ratio is [n, 1], and 0<n<1.Judge width whether within [n*kw, kw] and
Whether height is within [n*kh, kh], and kw is by width of key, and kh is button height.If both in range, by third
Font size s3As current font size, otherwise third font size is zoomed in and out to obtain current font size.The width of current font size character exists
Within [n*kw, kw] and height is within [n*kh, kh].
By the larger entering method keyboard of the current font size for calculating with after necessary adjustment, obtaining as shown in figure 5, obtaining
Current font size it is smaller entering method keyboard it is as shown in Figure 6.
