Present inventor finds through research, relative movement direction between needing in mode due to existing control display object convergent-divergent according to multiple touch point is determined to control display object and is amplified and still reduce, at least two fingers must be adopted to move such touch operation being not easy to one-handed performance over the display so just result in user, thus make user be difficult to accurately control display object convergent-divergent by one-handed performance.Therefore, can realize accurately controlling display object convergent-divergent by one-handed performance to make user, just need to enable user adopt a finger to move such touch operation being convenient to one-handed performance over the display to control display object convergent-divergent, this just makes cannot again according to the relative movement direction between multiple touch point when determining that control display object is amplified and still reduced.
Based on above-mentioned consideration, one of main thought of the application can comprise: when controlling display object convergent-divergent, can determine to amplify display object or reduce according to the difference in the motion track direction of single touch point, particularly, first direction and the such two kinds of different directions of second direction can be set, can display object be amplified when the motion track direction of single touch point is first direction, can display object be reduced when the motion track direction of single touch point is second direction.Now, because the judgement zoomed in or out display object realizes according to the motion track direction of single touch point, this makes user can adopt a touch operation pointing movement over the display, thus be convenient to user and realize controlling display object convergent-divergent by one-handed performance, make can control display object convergent-divergent exactly by one-handed performance.
Based on above-mentioned basic thought, in an exemplary application scene of the application, first in response to the first touch operation for display object single touch point movement, the motion track of described touch point can be obtained; Then according to the motion track of described touch point, the direction of described motion track can be determined; Afterwards, can be first direction in response to the direction of described motion track, described display object is amplified, and the display object after display amplification, or, can be second direction in response to the direction of described motion track, described display object is reduced, and show the display object after reducing; Wherein, described first direction is different from described second direction.
It should be noted that above-mentioned exemplary application scene is only spirit for the ease of understanding the application and principle and illustrates, the embodiment of the application is unrestricted in this regard.On the contrary, the embodiment of the application can be applied to applicable any scene.
It will also be appreciated that, in above-mentioned exemplary application scene and the various illustrative embodiments of the application described below, the action of the application's embodiment can be by client executing, or also part can be performed by server by client executing, part, or can also be performed by server completely.The application is unrestricted in executive agent, as long as perform the action disclosed in the application's embodiment.
After describing the main thought of the application, below in conjunction with accompanying drawing, describe the various non-limiting embodiment of the application in detail.
See Fig. 1, show in the application the process flow diagram of the embodiment of the method 1 controlling display object convergent-divergent.In the present embodiment, such as specifically can comprise the following steps:
S101, in response to the first touch operation for display object single touch point movement, obtain the motion track of described touch point.
Wherein, first touch operation can be a kind of operation for triggering the control of display object convergent-divergent for user provides, screen shows this display object, when user triggers the first touch operation for this display object, the motion track of touch point can be obtained, so that the follow-up direction according to motion track determines that carrying out amplification display to display object still reduces display.Wherein, what touch point represented can be the position contacting with screen and perceived by electronic equipment, and what the first touch operation represented can be the action that user adopts single touch point continuous moving on screen.
Be understandable that, in order to distinguish for trigger display object convergent-divergent control the first touch operation with for triggering other touch operations of other functions, can require that under the first touch operation single touch point adopts specific track to move.Such as, in some embodiments, under first touch operation, the motion track of single touch point can be the circular arc track that touch point rotates, now, not only for the trigger action mode controlling display object convergent-divergent, the touch operation mode adopting single touch point in rotary moving can so that user understands and grasps, and adopt the touch operation of single touch point linearly movement to trigger the control of display object convergent-divergent owing to avoiding, make the first touch operation can be different from for triggering the conventional touch operation function such as switching before and after picture, thus avoid for trigging control display object convergent-divergent the first touch operation and for trigger other functions conventional touch operation between clash.
It should be noted that, in the present embodiment, in response to the first touch operation, multiple different embodiment can be adopted to realize the acquisition of motion track.
In some embodiments of the present embodiment, the convergent-divergent of an execution display object can be removed in response to user's one time the first touch operation, particularly, the acquisition of motion track is performed again after the first touch operation is complete, the motion track obtained can be under this first touch operation touch point all regions of process, namely the starting point of this motion track is first coordinate points that under the first touch operation, user contacts on screen, terminal is last coordinate points that under the first touch operation, user contacts on screen (namely user frame out coordinate points).
In other embodiments of the present embodiment, consider whether user normally can reach expection in the effect of operation limit, limit observation display object convergent-divergent when controlling display object convergent-divergent, therefore, check for the ease of operation limit, user limit, can perform in the process of first touch operation user and obtain motion track several times, thus realize carrying out convergent-divergent to display object in multiple times, in real time.Particularly, S101 such as can comprise: in response to the first touch operation for display object single touch point movement, monitors the current track length of described touch point movement; Threshold length is reached in response to monitoring described current track length, obtain the motion track of track corresponding to described current track length as described touch point, and reset described current track length, return the current track length of described monitoring described touch point movement, until described first touch operation terminates.Now, under the one-time continuous single-point of user touches the first touch operation of movement, when the course length of touch point movement reaches threshold length, one section of motion track can be got and utilize this section of motion track to enter the subsequent step of S101 to realize carrying out a convergent-divergent to display object, simultaneously again using the terminal of this section of motion track as the starting point of next section of motion track, again the course length of touch point movement is monitored, circulate with this, thus realize touching in moving process at the one-time continuous single-point of user carrying out convergent-divergent to display object in real time.Such as, shown in Fig. 2 a, to suppose in first touch operation of user touch point be from A1 through A2, A3 continuous moving to A4, each acquisition in A2, A3 and A4 place motion track can be arrived in touch point respectively; Now, under this first touch operation, display object cocondensation has put three times; Be when obtaining A2 place in touch point for the first time, corresponding movement is estimated as A1 ~ A2; Second time is when obtaining A3 place in touch point, and corresponding movement is estimated as A2 ~ A3; Be when obtaining A3 place in touch point for the third time, corresponding movement is estimated as A3 ~ A4.
S102, motion track according to described touch point, determine the direction of described motion track.
In the present embodiment, amplify due to display object and need to determine according to the motion track direction of single touch point with the control reduced, so after the motion track obtaining touch point, just need the direction determining this motion track.
Such as, move in examples of traces in the aforementioned circular arc mentioned, for controlling the sense of rotation that display object amplification and the direction reduced can be motion tracks, particularly, for judging that the first direction that display object is amplified can be clockwise direction or counter clockwise direction, for judging that the second direction that display object reduces then can be contrary with first direction.More specifically, when first direction is clockwise direction, second direction is counterclockwise; When first direction is counter clockwise direction, second direction can be clockwise direction.Wherein, clockwise motion track such as can see shown in Fig. 2 a, and anticlockwise motion track such as can see shown in Fig. 2 b.Certainly, be understandable that, if the track that user adopts single touch point to move and produces is irregular, such as, irregular motion track shown in Fig. 2 c, owing to cannot determine to zoom in or out display object, now can not carry out convergent-divergent to display object.
Be understandable that, determine on the embodiment basis of display object convergent-divergent in the sense of rotation of aforementioned employing motion track, sense of rotation can be such as determined by the tangential parameter of motion track.Particularly, S102 such as can comprise: to gather on described motion track in the moving process of described touch point multiple coordinate points of process; Tangential direction and the tangential acceleration of described motion track is calculated according to described multiple coordinate points; The sense of rotation of described motion track is determined according to described tangential direction and described tangential acceleration.Wherein, described coordinate points can be screen detects the position that touch point is contacted.
S103, be first direction in response to the direction of described motion track, described display object amplified, and display amplify after display object.
S104, be second direction in response to the direction of described motion track, described display object reduced, and display reduce after display object.
Wherein, described first direction is different from described second direction.
In some embodiments of the present embodiment, display object normally carries out showing with certain displaying ratio, therefore, when carrying out convergent-divergent to display object, first can calculate the displaying ratio after convergent-divergent.Particularly, the amplification mode of display object such as can comprise: calculate the displaying ratio after amplifying according to up-sizing, and carries out amplification process according to the displaying ratio after amplifying to described display object; Wherein, described up-sizing is determined by the length of described motion track; Correspondingly, the mode that reduces of display object such as can comprise: calculate the displaying ratio after reducing according to minification, and reduce process according to the displaying ratio after reducing to described display object; Wherein, described minification is determined by the length of described motion track.Be understandable that, because up-sizing and minification can be determined by the length of motion track, therefore, obtain on the basis of the embodiment of motion track when reaching threshold length in conjunction with aforementioned course length, up-sizing and minification are fixed values determined by threshold length, and this makes the varying dimensions of each convergent-divergent of display object be all identical.
Furthermore, in other embodiment, calculate on the basis of displaying ratio adopting up-sizing and minification, cause unintelligible to prevent display object excessive or too small, a maximum displaying ratio and minimum displaying ratio can also be set, ability Zoom display object during to make the displaying ratio after convergent-divergent only in maximum displaying ratio and minimum displaying ratio limited range.Particularly, described according to amplify after displaying ratio to described display object carry out amplifications process, can be specially: in response to amplify after displaying ratio be not more than maximum displaying ratio, according to amplify after displaying ratio to described display object carry out amplification process; Correspondingly, describedly according to the displaying ratio after reducing, process is reduced to described display object, can be specially: be not less than minimum displaying ratio in response to the displaying ratio after reducing, according to the displaying ratio after reducing, process be reduced to described display object; Wherein, described maximum displaying ratio is greater than described minimum displaying ratio.Be understandable that, if the displaying ratio after amplifying is greater than maximum displaying ratio, no longer can carries out amplification process to display object, but keep the display object size of current display constant; Correspondingly, if the displaying ratio after reducing is less than minimum displaying ratio, no longer can reduce process to display object, but keep the display object size of current display constant.
In other embodiments of the present embodiment, when showing the display object after convergent-divergent, because the displaying ratio of display object changes, the display object part that on-screen display (osd) area can carry also there occurs change, and this could show with regard to needing the display object after to convergent-divergent to carry out cutting.Particularly, for the display object after amplification, its display mode specifically can comprise: using current zoom basic point as the central point of on-screen display (osd) area, according to described on-screen display (osd) area, cutting is carried out to the display object after amplification, and be positioned at the part of described on-screen display (osd) area after showing described display object cutting; Correspondingly, for the display object after reducing, its display mode specifically can comprise: using current zoom basic point as the central point of on-screen display (osd) area, according to described on-screen display (osd) area, cutting is carried out to the display object after reducing, and be positioned at the part of described on-screen display (osd) area after showing described display object cutting.
Being understandable that, in other embodiment, when carrying out cutting to the display object after convergent-divergent, different current zoom basic points can being adopted based on different considerations.
In some cases, user knows its convergent-divergent basic point needed, now current zoom basic point can be fixed on the central point of current screen display region when showing the display object after convergent-divergent, the convergent-divergent basic point that user can be needed controls display object convergent-divergent after moving to the central point of current screen display region again.Such as, if user knows its regional location that will search when convergent-divergent map, when current zoom basic point is fixed on the central point of current screen display region, user controls map convergent-divergent after its regional location that will search can being placed in the central point of current screen display region again, thus the convergent-divergent of map just can be made to carry out based on its regional location that will search.
In other cases, user does not know its convergent-divergent basic point needed, but constantly find and adjust its convergent-divergent basic point needed based on the display object after convergent-divergent, now current zoom basic point can be set to the terminal (also the position at current place, touch point) of motion track when showing the display object after convergent-divergent, user constantly can adjust the terminal change of touch point movement according to the display object of real-time convergent-divergent when controlling display object convergent-divergent.Such as, if user does not know its regional location that will search when convergent-divergent map, but go to find its regional location that will search based on the map after convergent-divergent, when current zoom basic point is set to the terminal of motion track, user can adjust motion track terminal according to the map of real-time convergent-divergent needs continuation to find the regional location of target location to it, thus the convergent-divergent of map just can be made to control to realize in the operating process of display object carrying out based on the changing searching region of user user, and could adjust the convergent-divergent basic point of searching region to fixed position without the need to user's operation controlling display object convergent-divergent of stopping when finding area change, make the operation of user easier.
In order to meet the demand of user to convergent-divergent basic point under above-mentioned two kinds of different situations simultaneously, in some embodiments, a kind of zoom mode can be provided respectively for above-mentioned two kinds of different current zoom basic point set-up modes, the central point of current screen display region is adopted as convergent-divergent basic point to control display object convergent-divergent put fixed mode centered by current zoom pattern under, the terminal of motion track is adopted as convergent-divergent basic point to control display object convergent-divergent put follow the mode centered by current zoom pattern under, and pass through the switching of two kinds of current zoom patterns, the convergent-divergent basic point that user selects different set-up mode in varied situations can be realized.Particularly, based on the embodiment that two kinds of zoom mode switch, such as can also comprise in the present embodiment: put fixed mode situation centered by current zoom pattern under, in response to the second touch operation keeping the first threshold time constant for position, described display object touch point, described current zoom pattern is switched to central point follow the mode; When putting follow the mode centered by described current zoom pattern, there is not any touch operation in response in the Second Threshold time, described current zoom pattern is switched to described central point fixed mode; Wherein, when described first touch operation occurs, if put fixed mode centered by described current zoom pattern, described current zoom basic point is the central point of current screen display region, if put follow the mode centered by described current zoom pattern, described current zoom basic point is the terminal of described motion track.
It should be noted that, in the embodiment that above-mentioned zoom mode switches, the trigger condition switching to central point follow the mode is the second touch operation keeping the first threshold time constant for position, described display object touch point, and to switch to the fixed mode trigger condition of central point be that any touch operation did not occur in the Second Threshold time, this is more common relative to situation about not knowing owing to considering that user knows the situation of the convergent-divergent basic point required for it, central point fixed mode is the zoom mode more commonly used relative to central point follow the mode, for this reason, switch to central point fixed mode and have employed triggering mode without the need to user operation, and switch to central point follow the mode and have employed the triggering mode needing user operation.In addition, what the second touch operation for switching to central point follow the mode adopted is that touch point keeps the first threshold time constant, the i.e. length touch operation of pressing, this be on the one hand in order to avoid user short by false triggering, be the one-handed performance for the ease of user on the other hand.
By the technical scheme of the present embodiment, due to employing is determine to amplify display object or reduce according to the difference in the motion track direction of single touch point, therefore, user is by performing the single-point touch operation of single touch point movement for display object, just can realize the control to display object convergent-divergent, this makes user only can adopt a touch operation pointing movement over the display, thus be convenient to user and realize controlling display object convergent-divergent by one-handed performance, make can control display object convergent-divergent exactly by one-handed performance, for user brings better experience.
