Detailed description of the invention
Below in conjunction with accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Generally can with various different configurations arrange and design with the assembly of the embodiment of the present invention that illustrate described in accompanying drawing herein.Therefore, below the detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit claimed the scope of the present invention, but is merely representative of the selected embodiment of the present invention.Based on embodiments of the invention, the every other embodiment that those skilled in the art obtain under the premise not making creative work, broadly fall into the scope of protection of the invention.
Below in conjunction with the drawings and specific embodiments of the present invention, technical scheme is clearly and completely described.
First the term related in the embodiment of the present invention is introduced.
Inertia slip initial velocity: referring to that touching body slide occurs on touch screen and leaves the slip initial velocity of display window corresponding when touching screen, it is determined by the sliding speed touched when body leaves touch screen.
Velocity coeffficient: for adjusting the constant of inertia sliding speed of display window, and the value of this velocity coeffficient can according to the inertia slip initial velocity of different display windows self-adaptative adjustment.
With reference to slip initial velocity: being the inertia slip initial velocity of desirable display window, it is empirical value, and display window can obtain desirable or desired sliding distance with this speed when sliding.
Inertia slip initial velocity, sliding speed, reference slip initial velocity and the sliding distance referred here to, traditional long measure (such as meter per second, rice) can be adopted to represent, it would however also be possible to employ pixel unit (such as pixel/second, pixel quantity) represents.Because the present invention relates to screen to show, it is advantageous to adopt pixel unit (such as pixel/second, pixel quantity) to represent.
In order to improve the technical problem that existing touch screen sliding method exists, such as when the sensor that the smart mobile phone of the smart mobile phone that different manufacturers produce or the different series that same manufacturer produces adopts and driving circuit exist different, even if will result in the same dynamics slip touch screen of user's finger, the sliding distance of the display window obtained also is different.It addition, for same smart mobile phone, user is desirable for being in a range of different dynamics to the touch screen that slides, and is attained by identical sliding distance.
Based on above-mentioned purpose, the embodiment of the present invention carrys out the inertia sliding speed of self-adaptative adjustment display window by the velocity coeffficient that the inertia of self-adaptative adjustment display window slides, as long as the inertia slip initial velocity of display window is in the scope of a license, just can change the inertia sliding speed of display window by changing velocity coeffficient, thus controlling the sliding distance of display window.Velocity coeffficient is improved will pass through the inertia slip initial velocity product with velocity coeffficient to improve inertia sliding speed when the inertia slip initial velocity of display window is on the low side；Vice versa, namely reduces velocity coeffficient when the inertia slip initial velocity of display window is higher will pass through the inertia slip initial velocity product with velocity coeffficient to reduce inertia sliding speed.
Wherein, the inertia slip initial velocity of described display window is in the scope of a license, refer to finger according to user touch screen occurs slide and leave touch screen time corresponding display window inertia slip initial velocity judge the expectation purpose of user: when the inertia slip initial velocity of display window is in the scope of a license, it is believed that user's expectation carries out a slide behavior, although employing different dynamics slip touch screen, but it is attained by identical sliding distance；When the inertia slip initial velocity of display window is not in the scope of described license, it is believed that a segment distance that user's desired display window sliding is less or the bigger segment distance that slides.Generally, the velocity interval of described license is based on the scope of the obtained empirical value of the use habit of most users.
Touch screen control method by sliding and the touch screen slide control device of the present invention are described more fully below.
Fig. 1 illustrates the flow chart of the touch screen control method by sliding of the present invention.As it is shown in figure 1, the touch screen control method by sliding that the embodiment of the present invention provides, including:
Step S101: detection touches the slide that occurs on the touchscreen of body, obtains the positional information of display window corresponding when described slide terminates, glide direction and inertia slip initial velocity.
In order to accurately detect slide, prevent false triggering or touch detection excessively sensitivity, typically require the detection to slide and add qualifications: namely touching body laterally or longitudinally slip one segment distance on the touchscreen, this sliding distance is more than or equal to predeterminable range.If longitudinal sliding motion distance more than or equal to predeterminable range it is determined that occur longitudinal sliding motion operation；If sliding laterally distance more than or equal to predeterminable range it is determined that slide laterally operation.This predeterminable range can be set according to different types of machine.
In brief, the slide that detection touch body occurs on the touchscreen includes: whether detection touches body sliding distance laterally or longitudinally on the touchscreen be more than or equal to predeterminable range, if so, then judges to there occurs slide on described touch screen.
Final position when detection touches the initial position of body touching touch screen and leaves touch screen, this touch body is usually the finger of user；It can also be felt pen etc. common on market.Described initial position is the initial contact point of user's finger coordinate in described touch screen, and described final position is user's finger touch points when leaving touch screen coordinate in described touch screen.Sliding distance and the direction of user's finger just it is able to know that by initial position co-ordinates and final position coordinate.This sliding distance can be represent by long measure (such as mm), it is also possible to is represent by pixel quantity.Here for long measure, the slide in detection longitudinally, the difference of the vertical coordinate of final position and the vertical coordinate of initial position is sliding distance；Detection slide transversely, the difference of the abscissa of final position and the abscissa of initial position is sliding distance.It will be appreciated by those of skill in the art that the touch screen for different size and kind, it is determined that occur the threshold value (predeterminable range) of the sliding distance of slide to be also likely to be different.Such as, for the touch screen of certain model, when sliding distance is more than a predeterminable range such as 3mm, it is believed that this time sliding is effective slide, rather than false triggering.Certainly, the threshold value (predeterminable range) for determining whether the sliding distance of slide can also be set as other value according to practical application.
The method that judge slide be longitudinal direction is exemplified below: select 2-3 the touch points position that initial position, final position, initial position are optional to the sliding trace between final position, judge the abscissa of initial position, final position abscissa and optional 2-3 touch points position abscissa line whether point-blank, can there is deviation in limited range in the abscissa of certainly selected point, is namely approximately straight line and can assert that slide is longitudinal direction.Judge that the method that slide is horizontal direction is similar with it, repeat no more here.
Although illustrating with long measure (such as mm) here, those skilled in the art both knows about the use pixel unit method to determine sliding distance and glide direction, and any known method can use, and repeats no more here.
Obtain the positional information of display window corresponding when described slide terminates for obtaining coordinate figure.
Obtain the glide direction that glide direction is slide of display window.
The inertia slip initial velocity obtaining display window includes: sliding speed when leaving described touch screen according to described touch body determines the inertia slip initial velocity of described display window.Generally, the inertia slip initial velocity of display window can be approximated to be sliding speed when described touch body leaves described touch screen.Or, in order to for more accurate purpose, touch sliding speed when body such as user's finger or felt pen leave touch screen according to what get, utilize the characteristic of this touch screen, coefficient of friction etc. calculate as described in the inertia slip initial velocity of display window.
Touch screen can touch sliding distance shorter when body leaves touch screen and sliding time thereof by internal sensor collection, with this sliding distance divided by sliding time, just obtains sliding speed when touch body leaves described touch screen.
Step S102: determine the inertia sliding speed of described display window according to described inertia slip initial velocity self adaptation.
Determine that the inertia sliding speed of described display window includes according to described inertia slip initial velocity self adaptation:
The velocity coeffficient that the inertia of display window according to described inertia slip initial velocity self-adaptative adjustment slides；The product of the velocity coeffficient slided by the inertia of described inertia slip initial velocity and the described display window of self-adaptative adjustment is as the inertia sliding speed of described display window.
Self adaptation adopts its basic meaning.Thus, self-adaptative adjustment here refers to: automatically adjust to obtain the sliding distance of desired display window.Namely the inertia slip initial velocity size according to display window optionally adjusts automatically, is automatically adjusted when meeting preset requirement, is not automatically adjusted when being unsatisfactory for preset requirement, thus obtaining the treatment effect of the best.
The invention provides the first method of the velocity coeffficient that the inertia of display window according to described inertia slip initial velocity self-adaptative adjustment slides, including:
Judge that the inertia slip initial velocity of described display window is whether in default value range, namely judge that whether the inertia slip initial velocity of described display window is less than the first inertia slip initial velocity threshold value or whether more than the second inertia slip initial velocity threshold value, wherein this second inertia slip initial velocity threshold value is more than this first inertia slip initial velocity threshold value, if so, described velocity coeffficient is not then adjusted；Otherwise, calculate the product of described inertia slip initial velocity and velocity coeffficient, using its difference with the reference slip initial velocity preset as velocity shift value；The absolute value of described velocity shift value is compared with the velocity shifts threshold value preset, does not then adjust described velocity coeffficient when the absolute value of described velocity shift value is less than or equal to default velocity shifts threshold value, otherwise described velocity coeffficient is adjusted.
Below the enforcement of above-mentioned first method is described in detail.User sometimes thinks to browse webpage or by screen or search destination object line by line by screen on the touchscreen, now user slide dynamics that touch screen uses can be only small so that the inertia slip initial velocity of display window is also only small；User there be also occasions when to want with most fast browsing webpage, for instance expects the content that the top directly browsing webpage or bottommost shows, now user slide dynamics that touch screen uses can very greatly so that the inertia slip initial velocity of display window is also very big.User slide touch screen use dynamics excessive or too small time, being construed as user's desired display window should with low speed or high-speed slide, in other words, the sliding distance of desired display window is only small or very big, if now regulating the speed coefficient, thus user being expected the inertia sliding speed of the display window of low speed is heightened, or the inertia sliding speed of the display window of desired for user high speed is turned down, this has all run counter to the expectation purpose of user, is worthless.So, according to experiment experience, preset the value range of an inertia slip initial velocity, when inertia slip initial velocity drops in this value range preset, may determine that the once slip thinking that user expects him, although employing different dynamics slip touch screen, but display window can reach identical sliding distance；When inertia slip initial velocity is not in this value range preset, it can be determined that think that user's desired display window should with low speed or high-speed slide, it is desirable to reach different sliding distances.
It addition, ideally, the product of inertia slip initial velocity and velocity coeffficient should be equal to reference to slip initial velocity, but practically always have deviation.Subtracted each other by the two and obtain a velocity shift value, when the absolute value of this velocity shift value is less, it is believed that the product of inertia slip initial velocity and velocity coeffficient is approximately equal to reference to slip initial velocity, does not now adjust velocity coeffficient, coefficient of otherwise will regulating the speed.So, presetting the velocity shifts threshold value for comparing is empirical value, and it can be configured according to the demand of user and preference, compares by the absolute value of velocity shift value and this velocity shifts threshold value, determines whether to coefficient of regulating the speed.
In order to implement above-mentioned first method further, present invention also offers the first scheme for coefficient of regulating the speed, including:
Calculate the ratio with reference to slip initial velocity and described inertia slip initial velocity as the first reference value；
Calculate the difference of described first reference value and described velocity coeffficient, it is judged that described velocity coeffficient, whether less than first threshold, is if so, then adjusted to described reference value by the absolute value of described difference；Otherwise, described velocity coeffficient increased or reduce Second Threshold；Wherein, when described difference is more than 0 and be more than or equal to first threshold, described velocity coeffficient is increased Second Threshold；When described difference is less than 0 and less than or equal to negative first threshold, described velocity coeffficient is reduced Second Threshold；
By adjust after described velocity coeffficient respectively with the 3rd threshold value and more than the 3rd threshold value the 4th threshold ratio relatively, it is adjusted to the 3rd threshold value when the velocity coeffficient after adjusting is less than three threshold values, is adjusted to the 4th threshold value when the velocity coeffficient after adjusting is more than four threshold values.
Adopt described velocity coeffficient is defined to can not less than the 3rd threshold value, can not be advantageous in that more than the 4th this step of threshold value coefficient of regulating the speed further: be possible to prevent because some abnormal to cause that velocity coeffficient adjusts excessive or too small, can so that user in front and back repeatedly slip touch screen time display window sliding speed smoother, the difference not havinging slide anteroposterior speed is excessive, enhances the good experience of user.
Additionally, in practical operation, in order to prevent velocity coeffficient self-adaptative adjustment excessively frequent, the difference of above-mentioned reference value Yu velocity coeffficient generally can be done a size judge, if the absolute value of this difference is less than the 5th default threshold value, then think that described inertia slip initial velocity and the product of current velocity coeffficient are approximately equal to described with reference to slip initial velocity, so described velocity coeffficient need not be adjusted.5th threshold value would generally take the value being close to 0.This scheme is described below in detail.
Namely in order to implement above-mentioned first method further, present invention also offers the first scheme for coefficient of regulating the speed, including:
Calculate the ratio with reference to slip initial velocity and described inertia slip initial velocity as the first reference value；
Calculate the difference of described first reference value and described velocity coeffficient, judge that whether the absolute value of described difference is less than the 5th threshold value, if, then do not adjust described velocity coeffficient, otherwise judge that whether the absolute value of described difference is less than first threshold, if so, then described velocity coeffficient is adjusted to described first reference value；Otherwise, described velocity coeffficient increased or reduce Second Threshold；Wherein, when described difference is more than 0 and be more than or equal to first threshold, described velocity coeffficient is increased Second Threshold；When described difference is less than 0 and less than or equal to negative first threshold, described velocity coeffficient is reduced Second Threshold；
By adjust after described velocity coeffficient respectively with the 3rd threshold value and more than the 3rd threshold value the 4th threshold ratio relatively, it is adjusted to the 3rd threshold value when the velocity coeffficient after adjusting is less than three threshold values, is adjusted to the 4th threshold value when the velocity coeffficient after adjusting is more than four threshold values.
Described alternative plan also use described velocity coeffficient is defined to can not less than the 3rd threshold value, can not regulate the speed further coefficient more than the 4th this step of threshold value, its benefit is identical with above-mentioned first scheme, repeats no more here.
It addition, when slide occurs user on the touchscreen, be sometimes not necessarily required for self-adaptative adjustment velocity coeffficient.In order to prevent velocity coeffficient self-adaptative adjustment excessively frequent, and in order to make velocity coeffficient self-adaptative adjustment more accurate, present invention also offers the second method of the velocity coeffficient that the inertia of display window according to described inertia slip initial velocity self-adaptative adjustment slides, including:
Judge that the inertia slip initial velocity of described display window is whether less than the first inertia slip initial velocity threshold value or whether more than the second inertia slip initial velocity threshold value, wherein this second inertia slip initial velocity threshold value is more than this first inertia slip initial velocity threshold value；
If so, described velocity coeffficient is not then adjusted；
Otherwise, collecting described inertia slip initial velocity, and before collecting inertia slip initial velocity described in n-th, do not adjust described velocity coeffficient, wherein N is the integer more than or equal to 2；
Calculate the average inertia slip initial velocity of inertia slip initial velocity described in n times；
Calculate the product of described average inertia slip initial velocity and velocity coeffficient, using its difference with the reference slip initial velocity preset as velocity shift value；The absolute value of described velocity shift value is compared with the velocity shifts threshold value preset, does not then adjust described velocity coeffficient when the absolute value of described velocity shift value is less than or equal to default velocity shifts threshold value, otherwise, described velocity coeffficient is adjusted.
Here, Integer N can select occurrence according to system running environment and/or customer experience etc., for instance, N can be 4,5,6 or 7 etc..
In the process of specifically used the method, in order to alleviate the system storage burden to data, the amount of storage space collecting described inertia slip initial velocity can be determined according to the N occurrence adopted, such as N=4, since it is desired that collect 4 described inertia slip initial velocity, so fixing 4 memory spaces for preserving inertia slip initial velocity, after having collected 4 inertia slip initial velocity, the velocity amplitude previously collected can be override when regathering inertia slip initial velocity next time.
In order to implement above-mentioned second method further, present invention also offers the first scheme for coefficient of regulating the speed, including:
Calculate the ratio with reference to slip initial velocity and described average inertia slip initial velocity as the first reference value；
Calculate the difference of described first reference value and described velocity coeffficient, it is judged that described velocity coeffficient, whether less than first threshold, is if so, then adjusted to described first reference value by the absolute value of described difference；Otherwise, described velocity coeffficient increased or reduce Second Threshold；Wherein, when described difference is more than 0 and be more than or equal to first threshold, described velocity coeffficient is increased Second Threshold；When described difference is less than 0 and less than or equal to negative first threshold, described velocity coeffficient is reduced Second Threshold；
By adjust after described velocity coeffficient respectively with the 3rd threshold value and more than the 3rd threshold value the 4th threshold ratio relatively, it is adjusted to the 3rd threshold value when the velocity coeffficient after adjusting is less than three threshold values, is adjusted to the 4th threshold value when the velocity coeffficient after adjusting is more than four threshold values.
Also use for the described first scheme of second method described velocity coeffficient is defined to can not less than the 3rd threshold value, can not regulate the speed further coefficient more than the 4th this step of threshold value, its benefit is identical with the above-mentioned described first scheme for first method, repeats no more here.
In order to implement above-mentioned second method further, simultaneously in order to prevent velocity coeffficient self-adaptative adjustment excessively frequent, present invention also offers the first scheme for coefficient of regulating the speed, including:
Calculate the ratio with reference to slip initial velocity and described average inertia slip initial velocity as the first reference value；
