Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually exist
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but it is merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Below in conjunction with the drawings and specific embodiments of the invention, technical solution of the present invention is carried out clearly and completely
Description.
Term involved in the embodiment of the present invention is introduced first.
Inertia slides initial velocity: referring to that touching body, slide occurs on the touch screen and leaves corresponding when touching screen
The sliding initial velocity of display window, sliding speed when leaving touch screen by touch body determine.
Velocity coeffficient: for adjusting the constant of the inertia sliding speed of display window, and the value of the velocity coeffficient can root
Initial velocity is slided according to the inertia of different display windows and is adaptively adjusted.
With reference to sliding initial velocity: be that the inertia of ideal display window slides initial velocity, be empirical value, display window with
It can get ideal or desired sliding distance when the speed is slided.
The inertia referred here to slides initial velocity, sliding speed, with reference to sliding initial velocity and sliding distance, can be using biography
The length unit (such as meter per second, rice) of system indicates, can also be indicated using pixel unit (such as pixel/second, pixel quantity).Cause
For the present invention relates to screens to show, it is advantageous to be indicated using pixel unit (such as pixel/second, pixel quantity).
In order to improve existing touch screen sliding method, such as the intelligence when the production of different manufacturers
The sensor and driving circuit that mobile phone or the smart phone of the different series of same manufacturer production use exist
When different, it will result in and slide touch screen, the sliding distance of obtained display window even if the same dynamics of user's finger
It is different.In addition, user is desirable for sliding touching in a certain range of different dynamics for same smart phone
Screen is touched, identical sliding distance is attained by.
Based on above-mentioned purpose, the embodiment of the present invention by adaptively adjust display window inertia slide velocity coeffficient come
The inertia sliding speed of adaptive adjustment display window, as long as the range that the inertia sliding initial velocity of display window is permitted at one
It is interior, so that it may to change the inertia sliding speed of display window by changing velocity coeffficient, to control the sliding of display window
Distance.Velocity coeffficient is improved when the inertia of display window sliding initial velocity is relatively low will pass through inertia sliding initial velocity and speed
The product of coefficient improves inertia sliding speed；Vice versa, i.e., reduces when the inertia of display window sliding initial velocity is higher
Velocity coeffficient reduces inertia sliding speed will pass through the product of inertia sliding initial velocity and velocity coeffficient.
Wherein, the inertia sliding initial velocity of the display window refers to the hand according to user in the range of a license
Refer to and slide occurs on the touch screen and leaves the inertia sliding initial velocity of corresponding display window when touching screen to sentence
The expectation purpose of disconnected user: when the inertia sliding initial velocity of display window is in the range of a license, it is believed that user's phase
It hopes and carries out a slide behavior, although having used different dynamics sliding touch screens, be attained by identical sliding distance；
When display window inertia sliding initial velocity not in the range of the license, it is believed that user's desired display window sliding compared with
Small a distance or the biggish a distance of sliding.In general, the velocity interval of the license is made based on most users
With the range for being accustomed to obtained empirical value.
Touch screen control method by sliding and touch screen slide control device of the invention is described more fully below.
Fig. 1 shows the flow chart of touch screen control method by sliding of the invention.As shown in Figure 1, the embodiment of the present invention mentions
The touch screen control method by sliding of confession, comprising:
Step S101: detection touches the slide that occurs on the touchscreen of body, and it is right at the end of the slide to obtain
Location information, glide direction and the inertia for the display window answered slide initial velocity.
In order to accurately detect slide, prevent false triggering or touch detection too sensitive, it usually needs to sliding
Qualifications are added in the detection of operation: i.e. the laterally or longitudinally sliding a distance of touch body on the touchscreen, the sliding distance
More than or equal to pre-determined distance.If longitudinal sliding motion distance is greater than or equal to pre-determined distance it is determined that longitudinal sliding motion operation occurs；
If sliding laterally distance is greater than or equal to pre-determined distance it is determined that sliding laterally operation.The pre-determined distance can be according to not
The machine of same type is set.
In brief, it includes: that detection touches body on the touchscreen that detection, which touches the slide that body occurs on the touchscreen,
Sliding distance laterally or longitudinally whether be more than or equal to pre-determined distance, if so, determine cunning has occurred on the touch screen
Dynamic operation.
Final position when detection touches the initial position of body touching touch screen and leaves touch screen, the touch body are usually
The finger of user；It is also possible to felt pen etc. common in the market.The initial position is that the initial contact point of user's finger exists
Coordinate in the touch screen, the final position are touch points when user's finger leaves touch screen in the touch screen
Coordinate.Sliding distance and the direction of user's finger are just able to know that by initial position co-ordinates and final position coordinate.The sliding
Distance can be to be indicated with length unit (such as mm), is also possible to be indicated with pixel quantity.Here by taking length unit as an example,
Longitudinal slide is detected, the difference of the ordinate of the ordinate and initial position of final position is sliding distance；Detection is horizontal
Upward slide, the difference of the abscissa of the abscissa and initial position of final position are sliding distance.The technology of this field
Personnel determine that the threshold value that the sliding distance of slide occurs is (default it is understood that touch screen for different sizes and type
Distance) it may also be different.For example, for the touch screen of certain model, when sliding distance is greater than a pre-determined distance such as 3mm,
It is considered that this time sliding is effective slide, rather than false triggering.Certainly, for judging whether it is the cunning of slide
The threshold value (pre-determined distance) of dynamic distance also can be set as other values according to practical application.
The method for judging slide for longitudinal direction is exemplified below: selection initial position, final position, initial bit
2-3 touch points position optional on the sliding trace between final position is set, judges abscissa, the stop bit of initial position
The abscissa set and optionally the abscissa of 2-3 touch points position line whether point-blank, certainly selected by
Deviation can occur in limited range in the abscissa of point, that is, be approximately that straight line can assert that slide is longitudinal direction.Sentence
Disconnected slide is that the method for transverse direction is similar with its, and which is not described herein again.
Although being illustrated here with length unit (such as mm), those skilled in the art both knows about true using pixel unit
Determine the method for sliding distance and glide direction, any well known method can use, and which is not described herein again.
The location information of corresponding display window at the end of the slide is obtained to obtain coordinate value.
The glide direction for obtaining display window is the glide direction of slide.
The inertia sliding initial velocity for obtaining display window includes: sliding when leaving the touch screen according to the touch body
Speed determines the inertia sliding initial velocity of the display window.In general, the inertia sliding initial velocity of display window can be approximated to be
The sliding speed touched when body leaves the touch screen.Alternatively, in order to for more accurate purpose, according to the touching got
Sliding speed when body such as user's finger or felt pen leave touch screen is touched, the characteristic of the touch screen, such as coefficient of friction are utilized
Calculate the inertia sliding initial velocity of the display window.
Touch screen can touch body by internal sensor collection and leave sliding distance and its cunning shorter when touch screen
The dynamic time has just obtained touching sliding speed when body leaves the touch screen with the sliding distance divided by sliding time.
Step S102: the inertia sliding speed that initial velocity adaptively determines the display window is slided according to the inertia.
Initial velocity, which is slided, according to the inertia adaptively determines that the inertia sliding speed of the display window includes:
The velocity coeffficient that initial velocity adaptively adjusts the inertia sliding of the display window is slided according to the inertia；By institute
Described in the product conduct for stating the velocity coeffficient of the inertia sliding of inertia sliding initial velocity and the display window adaptively adjusted
The inertia sliding speed of display window.
Adaptively use its basic meaning.Adaptive adjustment here refers to as a result: in order to obtain desired display window
Sliding distance and adjust automatically.Initial velocity size selectively adjust automatically is slided according to the inertia of display window, when full
It is adjusted automatically when sufficient preset requirement, without adjust automatically when being unsatisfactory for preset requirement, to obtain optimal processing effect
Fruit.
The present invention provides the inertia slidings that the display window is adaptively adjusted according to inertia sliding initial velocity
The first method of velocity coeffficient, comprising:
Judge that the inertia sliding initial velocity of the display window whether in preset value range, that is, judges the display window
Whether the inertia sliding initial velocity of mouth slides initial velocity threshold value or whether be greater than the second inertia less than the first inertia is slided initial velocity
Threshold value is spent, wherein second inertia sliding initial velocity threshold value is greater than first inertia sliding initial velocity threshold value, if so, not adjusting
The velocity coeffficient；Otherwise, the product for calculating inertia the sliding initial velocity and velocity coeffficient, by it with preset with reference to sliding
The difference of initial velocity is as velocity shift value；The absolute value of the velocity shift value and preset velocity shifts threshold value are compared
Compared with, when the absolute value of the velocity shift value be less than or equal to preset velocity shifts threshold value when do not adjust the speed system then
Number, is otherwise adjusted the velocity coeffficient.
The implementation of above-mentioned first method is described in detail below.User sometimes thinks to browse by screen on the touchscreen
Webpage searches target object by screen or line by line, at this time user slide dynamics used in touch screen can very little so that
The inertia of display window slides initial velocity also very little；User is there be also occasions when want with most fast browsing webpage, such as expect directly clear
Look at webpage top or content that bottommost is shown, at this time user slide dynamics used in touch screen can be very big, to make
The inertia sliding initial velocity for obtaining display window is also very big.When the dynamics that user's sliding touch screen uses is excessive or too small, it should
Being interpreted as user's desired display window should be slided with low-speed or high-speed, in other words, it is desirable to the sliding distance very little of display window
Or it is very big, at this time if regulating the speed coefficient, so that user it is expected that the inertia sliding speed of the display window of low speed is turned up, or
Person turns down the inertia sliding speed of the display window of the desired high speed of user, and it is not that this, which has all violated the expectation purpose of user,
Desirable.So the value range of an inertia sliding initial velocity is preset according to experiment experience, when inertia sliding initial velocity is fallen in
In the preset value range, it can be determined that think that user it is expected his primary sliding, although different dynamics slidings has been used to touch
Screen, but display window can reach identical sliding distance；When inertia sliding initial velocity not in the preset value range, can sentence
It is disconnected to think that user's desired display window be slided with low-speed or high-speed, it is expected that reaching different sliding distances.
In addition, ideally, the product of inertia sliding initial velocity and velocity coeffficient should be equal to reference to sliding initial velocity,
But practically always have deviation.Subtract each other to obtain a velocity shift value by the two, when the velocity shift value absolute value compared with
Hour, it is believed that the product of inertia sliding initial velocity and velocity coeffficient is approximately equal to reference to sliding initial velocity, is not regulated the speed at this time
Coefficient, otherwise will regulate the speed coefficient.So presetting the velocity shifts threshold value for comparing is empirical value, it can basis
The demand and preference of user is configured, and is compared with the absolute value of velocity shift value with the velocity shifts threshold value, to sentence
The disconnected coefficient that whether to regulate the speed.
In order to further implement above-mentioned first method, the present invention also provides the first sides for coefficient of regulating the speed
Case, comprising:
It calculates with reference to the ratio of sliding initial velocity and inertia sliding initial velocity as the first reference value；
Whether the difference for calculating first reference value and the velocity coeffficient judges the absolute value of the difference less than
One threshold value, if so, the velocity coeffficient is adjusted to the reference value；Otherwise, the velocity coeffficient is increased or is reduced
Second threshold；Wherein, the velocity coeffficient is increased into second threshold when the difference is greater than 0 and is more than or equal to first threshold；
The velocity coeffficient is reduced into second threshold when the difference is less than 0 and is less than or equal to negative first threshold；
By the velocity coeffficient adjusted respectively with third threshold value and greater than the 4th threshold value comparison of third threshold value, work as tune
Velocity coeffficient after whole is adjusted to third threshold value when being less than third threshold value, when velocity coeffficient adjusted is greater than the 4th threshold value
When be adjusted to the 4th threshold value.
Using by the velocity coeffficient be limited to cannot be less than third threshold value, can not be greater than four threshold values the step for come
Coefficient of further regulating the speed is advantageous in that: can be prevented because certain exceptions cause velocity coeffficient to adjust excessive or mistake
It is small, user's sliding speed of display window when touch screen is repeatedly slided in front and back can be made smoother, be not in front and back
The difference of sliding speed is excessive, enhances the good usage experience of user.
In addition, in actual operation, velocity coeffficient adaptively adjusts excessively frequently in order to prevent, it generally can be by above-mentioned reference
Value and the difference of velocity coeffficient are done a size and are judged, if the absolute value of the difference is less than preset 5th threshold value, then it is assumed that
The product of the inertia sliding initial velocity and current velocity coeffficient is approximately equal to the reference sliding initial velocity, so not needing
Adjust the velocity coeffficient.5th threshold value would generally take be close to 0 value.This scheme is described below in detail.
In order to further implement above-mentioned first method, the present invention also provides second for coefficient of regulating the speed
Scheme, comprising:
It calculates with reference to the ratio of sliding initial velocity and inertia sliding initial velocity as the first reference value；
Whether the difference for calculating first reference value and the velocity coeffficient judges the absolute value of the difference less than
Otherwise five threshold values judge whether the absolute value of the difference is less than first threshold if so, not adjusting the velocity coeffficient, if
It is that the velocity coeffficient is then adjusted to first reference value；Otherwise, the velocity coeffficient is increased or is reduced the second threshold
Value；Wherein, the velocity coeffficient is increased into second threshold when the difference is greater than 0 and is more than or equal to first threshold；When described
Difference reduces second threshold less than 0 and when being less than or equal to negative first threshold by the velocity coeffficient；
By the velocity coeffficient adjusted respectively with third threshold value and greater than the 4th threshold value comparison of third threshold value, work as tune
Velocity coeffficient after whole is adjusted to third threshold value when being less than third threshold value, when velocity coeffficient adjusted is greater than the 4th threshold value
When be adjusted to the 4th threshold value.
The alternative plan, which also uses, to be limited to the velocity coeffficient that cannot be less than third threshold value, can not be greater than the
The step for four threshold values coefficient of further regulating the speed, benefit is identical as above-mentioned first scheme, and which is not described herein again.
In addition, sometimes not necessarily requiring adaptively to adjust when a slide occurs on the touchscreen for user
Whole velocity coeffficient.Velocity coeffficient adaptively adjusts excessively frequently, and in order to adjust velocity coeffficient adaptively more in order to prevent
Accurately, the present invention also provides slide the speed that initial velocity adaptively adjusts the inertia sliding of the display window according to the inertia
Spend the second method of coefficient, comprising:
Whether either less than the first inertia sliding initial velocity threshold value to judge the inertia sliding initial velocity of the display window
No to be greater than the second inertia sliding initial velocity threshold value, wherein second inertia sliding initial velocity threshold value is greater than first inertia sliding just
Threshold speed；
If so, not adjusting the velocity coeffficient；
Otherwise, the inertia sliding initial velocity is collected, and before being collected into the sliding initial velocity of inertia described in n-th,
The velocity coeffficient is not adjusted, and wherein N is the integer more than or equal to 2；
The average inertia for calculating the sliding initial velocity of inertia described in n times slides initial velocity；
The product for calculating average inertia the sliding initial velocity and velocity coeffficient, by it with preset with reference to sliding initial velocity
Difference as velocity shift value；The absolute value of the velocity shift value is compared with preset velocity shifts threshold value, when
The absolute value of the velocity shift value does not adjust the velocity coeffficient then when being less than or equal to preset velocity shifts threshold value, no
Then, the velocity coeffficient is adjusted.
Herein, Integer N can select occurrence according to system running environment and/or customer experience etc., for example, N can
To be 4,5,6 or 7 etc..
During specifically used this method, in order to mitigate system to the storage burden of data, it can be used according to N
Occurrence collects the amount of storage space of the inertia sliding initial velocity, such as N=4 to determine, since it is desired that collecting described in 4 times
Inertia slides initial velocity, so fixing 4 for saving the memory spaces of inertia sliding initial velocity, when having collected 4 inertia
After sliding initial velocity, the velocity amplitude previously collected can be override when regathering inertia sliding initial velocity next time.
In order to further implement above-mentioned second method, the present invention also provides the first sides for coefficient of regulating the speed
Case, comprising:
It calculates with reference to the ratio of sliding initial velocity and average inertia sliding initial velocity as the first reference value；
Whether the difference for calculating first reference value and the velocity coeffficient judges the absolute value of the difference less than
One threshold value, if so, the velocity coeffficient is adjusted to first reference value；Otherwise, the velocity coeffficient increased or
Reduce second threshold；Wherein, the velocity coeffficient is increased by the second threshold when the difference is greater than 0 and is more than or equal to first threshold
