Simultaneously, from the technical standpoint that method realizes, the method for this instance explanation does not have the increase of resource overhead or the reduction of implementation efficiency with respect to prior art.
Embodiment two
See also Fig. 2; It is the process flow diagram of another embodiment of the method for a kind of paddling selection of the present invention; Present embodiment is chosen as application scenarios to utilize rectangular closed zone on the touch-screen type mobile phone that four candidate item are carried out paddling; Specify paddling and select the method for each candidate item, this method may further comprise the steps:
Step 201: four borders that show the closed region that is used on the touch-screen candidate item is selected;
Wherein, generally, candidate item is to use the frequency of this candidate item to sort according to the user, the candidate item that the user is commonly used more, and its ordering is forward more.Four candidate item are arranged in the present embodiment, therefore, corresponding four selection wires of four candidate item, and four selection wires have constituted the closed region of a rectangle, and four selection wires that constitute the closed region are shown.Article four, selection wire constitutes coboundary, lower boundary, left margin and the right margin of closed region respectively.See also Fig. 3, the synoptic diagram when it carries out the paddling selection for user among the present invention to four candidate item on the touch-screen.As shown in Figure 3, user's paddling selects the rule of candidate item to be: to be more arbitrarily starting point in the closed region, when marking the closed region through the coboundary of closed region, then select candidate item 1; When the lower boundary through the closed region marks the closed region, then select candidate item 2; When the left margin through the closed region marks the closed region, then select candidate item 3; When the right margin through the closed region marks the closed region, then select candidate item 4.That is, the coboundary is corresponding with candidate item 1, and lower boundary is corresponding with candidate item 2, and left margin is corresponding with candidate item 3, and right margin is corresponding with candidate item 4.
Need to prove; The present invention does not limit at the particular location of touch-screen the closed region that is used for the candidate item selection; It can be same zone with the input area that is used for the keyboard input; Also can be a zone that comprises said input area, can also be and input area zone fully independently.
Need to prove that also said candidate item specifically can be input content options, control types option or the designated order option under: input type option, the every kind of input type, for example when specified order be a period of time, the designated order option is preference.。Wherein, the input type option comprises: the words option of coded string conversion, input Pinyin option, input alphabet option, incoming symbol option are perhaps imported English completion option.
For example, when on touch-screen mobile phone, carrying out input operation, can candidate item be defined as preference, see also Fig. 4, it is a kind of scene synoptic diagram that preference is selected among the present invention.Promptly; When in the closed region, marking the closed region, can select the first-selected speech of current demonstration, when in the closed region, marking the closed region through left margin through the coboundary; Can select the preference of symbol, phonetic or letter; When in the closed region, marking the closed region through right margin, can select first operational order of setting, described operational order can be for input carriage return order, space order, eject the editing interface order or upgrade dictionary order etc.
Wherein, if current not when the dummy keyboard through input area carries out input operation, in the closed region, mark the preference that symbol can be selected in the closed region through left margin.As shown in Figure 4, after the user made the paddling selection operation, the symbol preference of selection was a comma.If the current dummy keyboard through input area has carried out input operation, in the closed region, mark the candidate item that phonetic or letter can be selected in the closed region through left margin.As shown in Figure 4, after the user made the paddling selection operation, the phonetic preference of selection was " POU ".
Step 202: whether the starting point that judges is imported on touch-screen is in the inside of closed region, if get into step 203, if deny repeating step 202;
Wherein, because therefore the closed region of rectangle, is example with an irregular pentagon in shape systematicness below, explain that when the closed region is arbitrary polygon the starting point how judges is imported is in the inside of closed region on touch-screen.
For example, when the starting point of on touch-screen, importing as the user was the M point, setting up with the M point was the rectangular coordinate system of initial point; Then irregular pentagonal five terminal A, B, C, D and the coordinate of E point under rectangular coordinate system are respectively: (x1-x0; Y1-y0), (x2-x0, y2-y0), (x3-x0, y3-y0), (x4-x0; Y4-y0) and (x5-x0, y5-y0).
The characteristics of four quadrants under the rectangular coordinate system are: first quartile: x＞0, y＞0; Second quadrant: x＜0, y＞0; Third quadrant: x＜0, y＜0; Four-quadrant: x＞0, y＜0.According to the coordinate of five end points under rectangular coordinate system; Said rectangular coordinate system judge constitute said closed region selection wire whether along the pointer direction or the quadrant number of crossing over counterclockwise is non-vanishing and said starting point not on said selection wire; If; Said starting point is in the inside of said closed region, if not, said starting point is not in the inside of said closed region.
For example, see also Fig. 5, its among the present invention when the closed region is irregular pentagon, starting point is at a synoptic diagram of outside, closed region.Wherein, when being counter clockwise direction, then in a four-quadrant rectangular coordinate system, if a selection wire AB, the A point is at the m quadrant, and the B point is at the n quadrant, and n＞m, and then selection wire AB crosses over n-m quadrant in the counterclockwise direction; If the B point was at first quartile at four-quadrant in A o'clock, then selection wire AB crosses over a quadrant in the counterclockwise direction.When being counter clockwise direction, then in a four-quadrant rectangular coordinate system, if a selection wire AB, the A point is at the m quadrant, and the B point is at the n quadrant, and n＜m, and then selection wire AB crosses over m-n quadrant in the clockwise direction; If the A point is at first quartile, then selection wire AB crossed over a quadrant in the clockwise direction at four-quadrant in B o'clock.
As shown in Figure 5; Be made as counterclockwise; In constituting said pentagonal selection wire AB, BC, CD, DE and EA, selection wire CD passes the first quartile and second quadrant respectively, owing to being counterclockwise from first quartile to second quadrant and crossing over a quadrant; Therefore, selection wire CD crosses over a quadrant in the counterclockwise direction; Selection wire DE passes second quadrant and first quartile respectively, owing to being CW from second quadrant to first quartile and crossing over a quadrant that therefore, selection wire DE crosses over a quadrant in the clockwise direction.The quadrant number that then whole pentagon is crossed in the counterclockwise direction just is zero, therefore, judges starting point M not in the inside of closed region, but in the outside of closed region.For example, see also Fig. 6, its among the present invention when the closed region is irregular pentagon, starting point is at a synoptic diagram of inside, closed region.Be set to counterclockwise; Then constitute among said pentagonal selection wire AB, BC, CD, DE and the EA; Selection wire AB passes four-quadrant and first quartile; Because be limited to first quartile for counterclockwise and cross over a quadrant from four-quadrant, then selection wire AB crosses over a quadrant in the counterclockwise direction; Selection wire CD passes the first quartile and second quadrant, owing to being counterclockwise from first quartile to second quadrant and crossing over a quadrant that then selection wire CD crosses over a quadrant in the counterclockwise direction; Selection wire DE pass second, third with four-quadrant since from first quartile to third quadrant all be the counter clockwise direction and cross-domain two quadrants, then selection wire DE crosses over two quadrants in the counterclockwise direction.Whole pentagon is crossed over four quadrants in the counterclockwise direction, and therefore, starting point M is in the inside of closed region.
Step 203: judges on touch-screen paddling and the paddling vector that forms whether through marking the closed region in a border of closed region, if, get into step 204, if not, get into step 205;
Wherein, when starting point M drops on the inside of closed region, can judges paddling point and the line segment between the starting point M of input in real time whether intersection point is arranged with the border of closed region.For example, in the process of user's paddling, the coordinate (x of paddling point M1; Y) change at any time, at this moment, confirm the straight line equation in real time according to M1 and two points of M; 5 straight-line equation Simultaneous Equations that this straight-line equation is confirmed with irregular pentagonal border respectively when can be in the hope of the separating of Simultaneous Equations, be judged and are found the solution the intersection point that obtains whether between paddling point and starting point; If; Then there is intersection point on the border of line segment between starting point and the paddling point and closed region, if not, then the border of line segment between starting point and the paddling point and closed region does not have intersection point; When not trying to achieve the separating of Simultaneous Equations, judge that also line segment and the border of closed region between starting point and the paddling point do not have intersection point.Simultaneously,, can confirm the input vector that the user imports marks the closed region through which border in the closed region, and then select and the corresponding candidate item in this border according to the formed intersection point in the border of line segment between starting point and the paddling point and closed region.
In addition; When starting point M drops on the inside of closed region; Also can judges the paddling point of input in real time whether in the outside of closed region, when the paddling point of user's input during closed region outside, then the input vector imported of user marks the closed region from the inside of closed region through said border; When the paddling point of user input during not closed region outside, then the input vector imported of user does not mark the closed region from the inside of closed region through said border.
Wherein, Can be that initial point is set up rectangular coordinate system with the paddling point of user input, according to the coordinate of five end points under this rectangular coordinate system, said rectangular coordinate system judge constitute said closed region selection wire whether along the pointer direction or the quadrant number of crossing over counterclockwise be zero; If; Said paddling point is in the outside of said closed region, if not, said paddling point is not in the outside of said closed region.
When the paddling point of user input during closed region outside; Confirm the straight line equation according to paddling point and two points of starting point; 5 straight-line equation Simultaneous Equations that this straight-line equation is definite with irregular pentagonal border respectively; According to the formed intersection point in the border of line segment between starting point and the paddling point and closed region, can confirm the input vector that the user imports marks the closed region through which border in the closed region, and then select and the corresponding candidate item in this border.
Step 204: judge that the user makes the paddling selection operation, select and mark the corresponding candidate item in border, process ends;
Step 205: judge that the user does not make paddling selection operation, process ends.
Need to prove that the closed region is except can confirming as arbitrary polygon according to the number of candidate item for the rectangle.
Can find out by the foregoing description; With respect to prior art; The embodiment of the invention shows the border of closed region, and whether marks the paddling selection operation is made in the closed region as the user criterion of identification from the inside of closed region through a border with the input vector of user's input; For the user, when marking the closed region when carrying out the paddling selection operation, be different from user's clicking operation more significantly according to the border of the closed region that demonstrates with through the border, avoiding user's clicking operation is the paddling operation by maloperation.
In addition, along with increasing of candidate item, be system of selection with the prior art, effective input range of corresponding some candidate item will reduce gradually, when the user selects candidate item, owing to anisotropy select wrong possibility will be big more.The embodiment of the invention is shown to the user with the border of closed region, and the mistake on the direction takes place when avoiding the user that candidate item is selected the direction of the paddling vector that the user can clearlyer import.
Simultaneously, from the technical standpoint that method realizes, the method for this instance explanation does not have the increase of resource overhead or the reduction of implementation efficiency with respect to prior art.
