Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Touch screen operation method for sensing provided by the present invention is a kind of operation method for sensing that is applicable to the touch panel device application program.This operation method for sensing can be completed the selected of in a plurality of objects two objects by simple paddling operation once, and the object after selected is recorded respectively, and produces the action command for two objects.
In the present invention, the point that in paddling operation, touch screen is pressed is " starting point ", and the point that touch screen discharges is " drop point " or " terminal point ", is called " leading portion " or " the initial segment " near the part of starting point, becomes " back segment " or " end section " near the part of drop point.
Fig. 1 is the paddling operation chart of this touch screen operation method for sensing.In operation 1 paddling track, three selected unique points are respectively p1, p2 and p3, find object B 1 near object A1 and the points of proximity p3 of ray p2-p1 by analysis, namely complete the instruction of " object A1 is to the B1 execution action ".Whether application program filters this instruction by rules selection, and gives instruction and move accordingly.similarly, the paddling track of operation 2 is chosen successively three unique points and is respectively p4, p5 and p6, the set direction action person of sending A2 by p5-p4, select the recipient of action by terminal point p6, but there is no obvious candidate actions recipient nearby, at this moment need a p6 is converted into site objects B4, the coordinate of object B 4 is (x6, y6) (x6 wherein, y6 comes from the transverse and longitudinal coordinate of p6 point in the application program coordinate system, may be also that other coordinate form is such as three-dimensional coordinate " x6, y6, z6 "), produce the instruction of " operation of object A2 to place B4 ".
Fig. 2 is in application program, the implementation schematic diagram of this touch screen operation method for sensing.Wherein, the category-A object may have object both to belong to category-A and also belong to category-B for the action recipient for the action person of sending, category-B object in the time of actual treatment.Arrow is the track of actual paddling operation.Operation C1 oppositely extends track and can find object A1, can find object B 1 near terminal point, can be interpreted as " command object A1 attacks B1 "; Operation C2 oppositely extends the guide rail that track can find object A2, finds object B 4 near terminal point, can successfully be interpreted as " order A2 attacks B4 ";What operation C3 and C4 realized is the operation of two fingers, can be regarded as once cooperation, requires object A3 and A4 concentrate firepower to attack the place ahead of B5, anticipation the movement of object B 5; Operation C5 oppositely extends track and can find object A5, can find object B 2 and B3 near terminal point, but B3 from terminal point more close to, preferential selected as the action recipient, the final command interpretation of operation C5 be " order A5 attack B3 ".
Below, in conjunction with Fig. 3, the idiographic flow of this touch screen operation method for sensing is described in detail.The method comprises the steps:
S101: the paddling operation of touch screen induction finger begins to operate method for sensing.
S102: the some string information that records the paddling track.
In carrying out the paddling operation, the storer recording user of touch panel device is from pressing touch-screen to the coordinate figure that discharges each tracing point the whole process of touch-screen (i.e. string).
Touch panel device detects paddling operation on touch-screen, begin the coordinate figure of each point of current paddling track is recorded and preserves.When setting up rectangular coordinate system, the upper left corner of preferred touch-screen is initial point, and level is to the right the X-axis positive dirction, is the Y-axis positive dirction vertically downward, determines the coordinate figure of each point in track in this coordinate.Wherein, for different software and operating system, choosing of coordinate system may be variant.
S103: the information such as the in-scope of paddling tracing point string, total length in analytical procedure S102 judge whether the paddling operation meets condition precedent.If do not meet, the operation method for sensing stops;
In this operation method for sensing, the condition precedent of judgement include but not limited to following some:
(1) mode of operation of application program is necessary for non-menu interface state, non-halted state and the non-state etc. that arranges; Otherwise it is invalid to be considered as this paddling operation.
(2) in application program, need to set the user's valid function scope that to regulate.Information indicating, toolbar and the advertising message etc. of application program operation often occupy certain screen scope, and it is invalid that the user operates in this scope.Suppose that the touch-screen upper left corner is initial point, the screen scope is (0,0)～(1280,720).And in application program the scope of setpoint distance screen coboundary 30, lower boundary 20, left margin 50, right margin 40 for staying white region, drop on when staying in white region when paddling operation, it is invalid that this time operation is considered as, be that user's effective opereating specification on screen is (50,30)～(1240,700).
(3) when above-mentioned two conditions satisfy, need the paddling track is done further judgement.The present invention carries out object select by a direction category information that string extracts, and therefore the total length of paddling track is had certain limitation.At first given two adjustable threshold values are respectively minimum value minLength and the maximal value maxLength of length; Then the some string of paddling track is used as broken line and asks its total length, if within length value drops on interval [minLength, maxLength], this time paddling is operating as valid function; Otherwise all be considered as invalid operation.Need to prove, the length of paddling operation does not need to increase because of the action person of sending and action recipient's distance, and operation can be very brief paddling.
S104: by analyzing the some string information of the paddling track that records in S102, complete paddling track of backward-predicted.This operation method for sensing need to predict that the completion user operates in effective range, the point on track reverse extending line.Suppose that six points on a track are followed successively by P1 to P6.And for reducing the paddling operating distance, during practical operation a paddling from a P4 to P6 one section.When the backward-predicted track, some P1, P2 be not in the effective range of user's operation, and the paddling track of backward-predicted arrives P5 to one section of P6 for some P3 to P4.
The backward-predicted of paddling track realizes by upper two points of paddling track initial section.These two points can more accurately reflect the paddling trajectory direction, and the point-to-point transmission movement locus is approximately straight line.And the reverse extending line of two points is reverse track.Wherein, claim in this operation method for sensing that two points are respectively First Characteristic point, Second Characteristic point.As follows with choosing of Second Characteristic point for First Characteristic point:
The starting point of the preferred paddling track of First Characteristic point.And may be because certain customers tremble due to hand or with reasons such as electric capacity gloves (having the irregular corner angle of the process generations such as stitchings) in actual mechanical process, some irregular points are arranged near causing the track starting point.And these irregular points can be influential to the judgement of paddling trajectory direction, need to give up current actual paddling operation starting point, and in selected point string the initial segment, track begins level and smooth point as the First Characteristic point again.
When carrying out the choosing of Second Characteristic point, at first need to set a length threshold dopeLength that can revise, this length threshold is the required minimum length of prediction paddling trajectory direction; Secondly the each point of putting terminal point from First Characteristic in the paddling track is traveled through; Then broken line length and the length threshold of First Characteristic point with each point compared; Choose at last broken line length and be not less than first point of length threshold as the Second Characteristic point.For example default length threshold is dopeLength, point in track is followed successively by a p1 to p9, the First Characteristic point of choosing is p2, successively an a p2～p9 is traveled through, and first that finds is the Second Characteristic point to the point that some p2 broken line total length is not less than dopeLength.
S105: in the paddling track certain limit of backward-predicted, find one or several qualified candidate actions persons of sending, and be that candidate target is given respectively weights according to factors such as distances; If there is no qualified candidate target, the operation method for sensing stops.
In this operation method for sensing, preferably set an adjustable angle threshold maxAngle; Secondly calculate respectively and can be used as coordinate points that action sends object to the vectorial A1～An of Second Characteristic point, First Characteristic is put the vectorial A0 of Second Characteristic point; Angle between difference compute vector A1～An and vectorial A0, selecting vector angle is the candidate actions person of sending less than the object of angle threshold maxAngle; According to the distance of candidate target to the paddling track of backward-predicted, the person of sending gives weights for candidate actions, treats to do screening in step S108 at last.
Wherein, be not limited to coordinate points when candidate target is chosen, if the field that this object occupies an or one parts in angle threshold, object also is the candidate actions person of sending (in Fig. 2 shown in operation 2).
S106: a selected unique point close to actual paddling operation terminal point.
The unique point of terminal point is the 3rd unique point, the terminal point of preferred paddling track.Equally may be because user's hand be trembled or has been with the reasons such as electric capacity gloves during the choosing of this unique point, irregular point is arranged near causing terminal point.Need the actual terminal point of cut-off point track for above-mentioned situation, select a hop count point in end in the paddling track, the mean value of selected point coordinate is the coordinate figure of the 3rd unique point.
Three points for example choosing are respectively P1(x1, y1), P2(x2, y2), P3(x3, y3), the 3rd unique point is made as P4(x4, y4), x4=(x1+x2+x3)/3, y4=(y1+y2+y3)/3.Wherein, for the end section count choose the time, need to set the adjustable threshold value minPointNum that counts, selected counting be not less than this threshold value and be not more than that track end section always counts 10%.
In the paddling track, the movement locus between Second Characteristic point and the 3rd unique point can be arbitrary shape, and namely terminal point can be in the non-optional position of staying white region of screen.The 3rd unique point can near First Characteristic point or near Second Characteristic point, also can overlap with First Characteristic point or Second Characteristic point.May put very little the decontroling apart from Second Characteristic point of paddling from First Characteristic when for example paddling operates, this moment, the 3rd unique point overlapped with Second Characteristic point; When the paddling operation trace was the figure of sealing, the 3rd unique point overlapped with First Characteristic point.
Near S107: find one or several qualified candidate actions recipients the 3rd unique point.Be that candidate target is given respectively weights according to factors such as distances.If there is no qualified candidate target, the operation method for sensing stops.
At first set an adjustable distance threshold maxDistance; Calculating can be used as action and receives the coordinate points of object and the distance of the 3rd unique point respectively; Choose with the distance of the 3rd unique point less than the object of distance threshold maxDistance as the candidate actions recipient; Last is that the candidate actions recipient gives weights according to the distance with the 3rd unique point, and preferred processing mode is that distance and weights are inversely proportional to, and then treats to do in step S108 last screening.
Some in particular cases, the 3rd unique point also can be converted into the orientation object that candidate actions receives, and there is no what target near this expression the 3rd unique point, the action person of sending needs operate (shown in the operation 2 in Fig. 1) to the position of the 3rd unique point.
S108: in conjunction with the screening principle of this operation method for sensing place application setting, and composed weights by candidate target in step S105 and S107, filter out one or more qualified combinations from all candidates' the action person of sending and action recipient's combination, if there is no qualified combination, the operation method for sensing stops.
The action person of sending and action recipient's screening principle preferred distance namely selects step S105, S107 to compose the object of weights maximum.For example the action person of sending can send object for the shortest action of paddling track of distance backward-predicted, and the action recipient can be for receiving object to the shortest action of the terminal point distance of paddling track.But for some special circumstances, the rationality of logic is simultaneously as the screening principle.
For example to send object A1 and A2 be L1, L2 to the distance of ray P2P1 to candidate actions.The distance of candidate actions recipient B1 and B2 to the three unique points is L3, L4.Distance L 1～distance L 4 is all in the coverage scope of application setting.Adopt preferred distance screening principle, due to distance L 1＜L2, distance L 3＜L4 determines that so the action person of sending is that object A1, action recipient are object B 1.And current instruction should be interpreted as " object A1 is to the B1 execution action ".Suppose that the candidate actions person of sending A1 and A2 represent respectively cannon, laser gun, candidate actions recipient B1 and B2 represent respectively mirror, battery, be operating as " cannon attack mirror " according to what distance principle was selected so, obviously explain it is illogical, and explain that " cannon obtains battery " neither be optimum, as be interpreted as " object A2 is to object B 2 execution actions " namely " laser gun obtains battery " should be more logical.
S109: to instruction or the explanation of qualified combination results, give this operation method for sensing place application program and process.
For one of qualified combination results " the action person of sending is to action recipient execution action " instruction.This instruction or explanation include but are not limited to following 3 types:
(1) directive property is arranged, such as " ordering the B of A challenging unit of unit ".
(2) reverse sensing, such as " the A device begins to equip the B energy source " also can be construed to " energy storehouse that the B energy source is provided to the A device ".
(3) ignore sensing, such as being interpreted as " A material and B material are synthetic " or " B material and A material are synthetic ".Wherein, the action person of sending and action recipient can be the kinds that belongs to different, can be the different objects of identical type, can also be same objects.Such as " command object A place under repair to oneself (medical treatment) ".The action recipient except a logic entity (as building, vehicle), can also be zone or the part in the abstract entities such as landform, painting canvas.For example " command object A attack coordinate be the place of (125,177) ", " ordering spray gun A to spray paint to zone corresponding to terminal point unique point ".
Need to prove, instruction produces in application program action and the of short duration behavior of non-once may be lasting.For example the instruction of " order a attack b " may continuously effective, until find new striking target or object b extinction or escape from the firing area etc. of a for object a.
S110: the operation method for sensing finishes.
This touch screen operation method for sensing is not limited to singly refer to realize, also can realize by two fingers, and for example the right-hand man to a terminal point paddling, completes target is made a joint attack on.The present invention had both reduced user's operation easier, the collaborative work of a plurality of objects of satisfying the demand again, stressed the operative scenario of timeliness.At the operating experience that improves touch-screen simultaneously, need the user to have thinking preferably to prepare before operation.And application program is balance difficulty and equipment loss, as required the time interval of this operation of proper extension method for sensing.
In addition, the present invention can realize by software and combination of hardware in the specific implementation.Wherein, touch-screen can the display application program interface as the interface of man-machine interaction; Storer is preserved the user and is pressed from touch-screen the information that touch-screen discharges tracing point string this whole operating process; Processor is the various information of user's input are resolved, processed, to the centralized control of touch-screen displaying contents.
The above has been described in detail touch screen operation method for sensing provided by the present invention.But for one of ordinary skill in the art, any apparent change of under the prerequisite that does not deviate from connotation of the present invention, it being done all will consist of infringement of patent right of the present invention, will bear corresponding legal liabilities.
