[embodiment]
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, in one embodiment, a kind of instruction triggers method based on touch-screen, comprises the following steps:
Step S102, the slide on monitoring touch-screen.
In one embodiment, the gesture in calling system slide on interface monitor touch-screen can be monitored.Such as, in android system (operating system being mainly used in mobile device of a kind of freedom based on Linux and open source code), call the slide of On Gesture Listener interface or Gesture Detector interface monitor touch-screen.
Step S104, the sliding trace that record slide produces.
When touch-screen occurs slide, the sliding trace that slide produces can be recorded.In one embodiment, such as, by the coordinate of the touch point of moving event object acquisition slide, in android system, by the coordinate of MotionEvent object acquisition touch point.The MotionEvent object record coordinate of touch point, along with the change of touch point position in slide, the coordinate of the touch point of MotionEvent object record is also change.Preserve the coordinate of MotionEvent object record and form coordinate sequence, the point that this coordinate sequence is corresponding can form sliding trace corresponding to slide.
Coordinate in the coordinate system that the straight line that coordinate in present specification refers to be parallel to base, viewing area (being made up of row's pixel of bottom) is x-axis, set up for y-axis with the straight line perpendicular to x-axis.
According to sliding trace, step S106, judges that whether slide arrives viewing area from the non-display area of touch-screen; When slide from non-display area and arrive viewing area, trigger preset instructions.Touch-screen comprises Trackpad and display board, and Trackpad is positioned on display board, is used in combination with display board.Trackpad be called touch area for the region receiving the signal that contact (such as pointer, finger etc.) inputs, the region for display frame of display board is then called viewing area.All regions in touch-screen outside viewing area are generally called non-display area.The touch area of some touch-screen is equal with the size of viewing area and overlap; And the area of the touch area of some touch-screen is greater than the area of viewing area, touch area covers viewing area and extends a part outward, such as, below viewing area, extends a part.This part can be used for placing some fixing icons, such as, return an interface icon, return desktop icons, menu icon etc.; Wherein, return an interface icon clicked time can trigger the instruction returning to an interface, return desktop icons clicked time can trigger the instruction returning desktop, the instruction of display menu can be triggered when menu icon is clicked, etc.
With the upright placement of touch-screen and to be just as the criterion description orientation facing to user in present specification.
In a first embodiment, the detailed process of step S106 is: according to sliding trace judge slide whether from the non-display area below the viewing area of touch-screen and direction up; When slide from non-display area and direction up time, trigger preset instructions.
In a second embodiment, the detailed process of step S106 is: judge the non-display area of slide whether above the viewing area of touch-screen according to sliding trace and direction down; When slide from non-display area and direction down time, trigger preset instructions.
In the third embodiment, the detailed process of step S106 is: according to sliding trace judge slide whether from the non-display area of the left, viewing area of touch-screen and direction turn right; When slide from non-display area and turn right in direction time, trigger preset instructions.
In the fourth embodiment, the detailed process of step S106 is: according to sliding trace judge slide whether from the non-display area of the right, viewing area of touch-screen and direction turn left; When slide from non-display area and turn left in direction time, trigger preset instructions.
The hereafter detailed process of description of step S106 based on the first above-mentioned embodiment, but the present invention should not be defined in the detailed process of the step S106 described in Examples below.In the second to four above-mentioned embodiment, the detailed process of step S106 can be analogized according to Examples below, does not repeat them here.
In one embodiment, judge whether slide comprises from the step of the non-display area below the viewing area of touch-screen according to sliding trace in the first above-mentioned embodiment: judge near bottom the viewing area whether starting point of sliding trace is positioned at touch-screen, if, then judge that slide is from the non-display area below viewing area, otherwise, judge that slide is not from this non-display area.
When the touch area of touch-screen is equal with viewing area size and when overlapping, the non-display area below viewing area is not included in touch area; And when touch-screen covering viewing area, touch area and toward it below extend a part time, the non-display area below viewing area comprise or part be included in touch area.
In one embodiment, when the touch area of touch-screen is equal with viewing area size and when overlapping, owing to cannot monitor the touch operation beyond viewing area, can judge whether the starting point of sliding trace is positioned at the base of viewing area.If the starting point of sliding trace is positioned at the base of viewing area, then judge that slide is from the non-display area below viewing area.Because in actual mechanical process, if the slide of reality is from the non-display area below viewing area really and does not depart from touch-screen in whole slide process, then the starting point of the sliding trace monitored must be positioned at the base of viewing area.
In another embodiment, when the touch area of touch-screen is equal with viewing area size and when overlapping, can judge that whether the starting point of sliding trace is lower than the predeterminated position of on the base of viewing area, this predeterminated position differs several pixel (being equivalent to vertical range close to 0) with the vertical range on base, if so, then judge that slide is from the non-display area below viewing area.Because predeterminated position only differs several pixel with the vertical range on base, may the starting point of slide be positioned between the base of viewing area and this predeterminated position hardly in actual mechanical process, therefore, general only from the starting point of the non-display area upward sliding guarantee sliding trace below viewing area lower than this predeterminated position on the base of viewing area, therefore, lower than the situation of this predeterminated position on the base of viewing area, the starting point of sliding trace is judged to be that slide is from the non-display area below viewing area, it is realistic operational circumstances.
And on the other hand, from non-display area slide upwards also likely the reason such as misoperation departed from touch-screen at some points of centre, thus in fact produce two sections of sliding traces, if and the starting point of second segment sliding trace by chance drops between the base of viewing area and this predeterminated position, then judge that slide is from the non-display area below viewing area, also realistic operational circumstances, and provide certain fault tolerant workspace for the misoperation of user.
In one embodiment, when touch-screen covering viewing area, touch area and toward it below extend a part time, due to the touch operation below viewing area in a segment distance can be monitored, can judge that the starting point of sliding trace is whether lower than the base of viewing area, if so, then judge that slide is from the non-display area below viewing area.
Concrete, in one embodiment, when the touch area of touch-screen is equal with viewing area size and when overlapping, can judge whether the ordinate of the starting point of sliding trace equals the ordinate on the base of viewing area, if so, then judge that slide is from the non-display area below viewing area; Or, can judge the ordinate of the starting point of sliding trace whether be less than the ordinate on the base of viewing area and several pixel distance and, if so, then judge that slide is from the non-display area below viewing area.Several pixel distance refers to line spread and the distance that represents in a coordinate system of the several pixel of continuous print.
When touch-screen covering viewing area, touch area and toward it below extend a part time, can judge whether the ordinate of the starting point of sliding trace is less than the ordinate on the base of viewing area, if so, then judge that slide is from the non-display area below viewing area.
Such as, with the pixel in the most lower left corner, viewing area be true origin, with one of viewing area bottom row pixel place straight line be x-axis, with row pixel place, the leftmost side, viewing area one straight line for y-axis sets up two-dimensional coordinate system.
When the touch area of touch-screen is equal with viewing area size and when overlapping, can judge whether the ordinate of the starting point of sliding trace equals 0, if so, then judge that slide is from the non-display area below viewing area; Or, can judge whether the ordinate of the starting point of sliding trace is less than several pixel distance, if so, then judge that slide is from the non-display area below viewing area.
When touch-screen covering viewing area, touch area and toward it below extend a part time, can judge whether the ordinate of the starting point of sliding trace is less than 0, if so, then judge slide from the non-display area below viewing area.
In one embodiment, can judge whether the ordinate of the starting point of sliding trace is less than the ordinate of terminating point and whether the distance of the horizontal ordinate of the horizontal ordinate of starting point and terminating point is less than the 3rd threshold value, if so, then judges the direction of slide upwards.
Hereafter continue, based on the first above-mentioned embodiment, the instruction triggers method based on touch-screen of the present invention is described.But the present invention should not be defined in hereinafter based on the instruction triggers method based on touch-screen described by the first above-mentioned embodiment.Can analogize according to Examples below based on the instruction triggers method based on touch-screen of first to fourth above-mentioned embodiment accordingly, not repeat them here.
In one embodiment, the above-mentioned instruction triggers method based on touch-screen also comprises step: judge whether slide displacement is upwards greater than first threshold according to sliding trace; When displacement upwards and is upwards greater than first threshold to slide from non-display area, direction, trigger preset instructions.The one that Fig. 2 shows in the present embodiment performs flow process.As shown in Figure 2, the above-mentioned instruction triggers method based on touch-screen comprises the following steps:
Step S202, the slide on monitoring touch-screen.
Step S204, when touch-screen there is slide, the sliding trace that record slide produces.
Step S206, according to sliding trace judge slide whether from the non-display area below the viewing area of touch-screen and direction up, and judge whether slide displacement is upwards greater than first threshold.
Concrete, can calculate slide displacement is upwards distance between the ordinate of the starting point of sliding trace and the ordinate of terminating point.
Step S208, when displacement upwards and is upwards greater than first threshold to slide from non-display area, direction, triggers preset instructions.
As shown in Figure 3, H1 represents the base 302 and the straight line on the base 302 of close viewing area 301 that are parallel to viewing area 301, conveniently checks, amplifies in figure to the distance between H1 and base, viewing area 301 302.It is the straight line of first threshold that H2 represents with the distance of H1; L1, L2, L3, L4, L5 represent sliding trace respectively; Wherein, the starting point of L1, L2 and L3 is lower than H1 and terminating point exceeds H2, so L1, L2 and L3 represent effective sliding trace that can trigger preset instructions; And exceed the terminating point of H1, L5 lower than H2 due to the starting point of L4, therefore, L3, L4 represent the invalid operation that cannot trigger preset instructions.
In above-described embodiment, when from non-display area, direction, displacement upwards and is upwards greater than first threshold to slide, just trigger preset instructions, can be filtered out some from the less unconscious operation of non-display area displacement upwards but upwards, avoid these operations to trigger preset instructions.
In one embodiment, the above-mentioned instruction triggers method based on touch-screen also comprises step: whether the time that monitoring slide stops at the terminating point place of this slide exceedes Second Threshold; When whether the time that slide upwards and at the terminating point place of this slide stops from non-display area, direction exceedes Second Threshold, trigger preset instructions.The one that Fig. 4 shows in the present embodiment performs flow process.As shown in Figure 4, the above-mentioned instruction triggers method based on touch-screen comprises the following steps:
Step S402, the slide on monitoring touch-screen.
Step S404, when touch-screen there is slide, the sliding trace that record slide produces.
Step S406, according to sliding trace judge slide whether from the non-display area below the viewing area of touch-screen and direction up, and the time that monitoring slide stops at the terminating point place of this slide whether exceed Second Threshold.
In one embodiment, monitoring slide comprises the following steps in the step whether time that the terminating point place of this slide stops exceedes Second Threshold: whether the touch point of monitoring slide stops at same place, if, then record the initial time that touch point stops (namely the position of touch point no longer changes), and calculate touch point stay time herein, and monitoring touch point whether stop herein after no longer shift to other places slide and namely stop, if slide herein stay time exceedes Second Threshold and touch point is no longer shifted to other places slide and namely stopped after stopping herein, then judge that the time that slide stops at the terminating point place of this slide exceedes Second Threshold, otherwise, judge that the time that slide stops at the terminating point place of this slide is no more than Second Threshold.
Step S408, when whether the time that slide upwards and at the terminating point place of this slide stops from non-display area, direction exceedes Second Threshold, triggers preset instructions.
In above-described embodiment, when whether the time that slide upwards and at the terminating point place of this slide stops from non-display area, direction exceedes Second Threshold, just trigger preset instructions, the time shorter unconscious operation that some upwards but at terminating point place stop from non-display area can be filtered out, avoid these operations to trigger preset instructions.
In one embodiment, when slide from non-display area, direction displacement upwards, be upwards greater than first threshold and the time stopped at the terminating point place of this slide exceedes Second Threshold time, trigger preset instructions.
In one embodiment, above-mentioned preset instructions can be but is not limited to link order or move etc. is reduced in display frame.
Concrete, link order can be used for instruction and returns to an interface, and on this, an interface is the interface of last display in the interface shown before the interface of current display.Display frame is reduced move and be can be used for indicating and carried out according to a certain percentage reducing by the picture window of display and drawn close to the touch-screen corner that the gesture gripping touch panel device is close by picture window, namely, if grip the gesture of touch panel device near some corners (such as the lower right corner) of touch-screen, then picture window is drawn close to this corner, be hold by one hand touch panel device to facilitate and rely on this one-handed performance touch-screen.
