Please join and consult Fig. 3 A, the preferred embodiment that sliding gesture judging method is swept at edge of the present invention includes following steps:
Be preset with a first area D_right, wherein this first area D_right and this contactor control device 10 1 lateral margins keep one apart from d1; The i.e. induction upper surface of base plate of this contactor control device 10 definition has this first area, and this first area and one lateral margin keep a distance;
In a Preset Time, read several positional informations of object on this contactor control device 10;
Judge whether the first stroke positional information in several information drops in this first area;
If so, judge between this first stroke positional information and other positional informations and whether have displacement difference d11; And
If have, and this displacement difference is while being greater than a preset value, and judgement action is for sweeping sliding gesture in edge; Wherein, this preset value according to generally sweep sliding gesture by this first area sweep slip velocity degree and this contactor control device is established default sweep time.
Shown in Fig. 2 and Fig. 3 A to Fig. 3 C, this contactor control device can be planned at most three right sides, a left side, upper first area D_right, D_left, D_up, for sweeping of different directions is sliding, uses.Therefore can be positioned at after the first stroke positional information on this contactor control device reading thing, first judgement falls into three right sides, a left side, upper first area D_right, D_left, D_up Na mono-district, then determines whether to sweep sliding gesture for edge.
First coordinate shown in Fig. 3 A, if read in the first stroke positional information S10 in the t1 time, and object is really positioned at the upper S11 of right first area D_right, in the t2 time, read next record positional information S111 again, calculate afterwards displacement difference between these two positional informations, and judge whether this displacement difference surpasses this preset value S112; If so, be judged as edge and sweep sliding gesture S113; Otherwise, read in again next record positional information and the first stroke positional information is compared displacement difference, until in Preset Time, do not have the displacement difference of arbitrary positional information and the first stroke positional information to be greater than this preset value S114, then by rearmost position information output S115.
Due to the margo dexter of this right border region D_right near contactor control device 10, therefore be used for judging by standard and turn left and sweep sliding gesture by the right side, therefore can further adding, the present invention sweeps sliding direction step, be about to after each positional information is compared with its next record positional information determine an article displacement direction, when all sense of displacement all meet a lateral margin by this contactor control device 10 to contactor control device 10 third sides to (sweeping sliding direction), and this displacement difference has been greater than this preset value, just judgement action is swept gesture for edge cunning; With this right first area D_right, can be determined by X-axis coordinate Xa, the Xa+1 of each positional information and next record positional information the whether satisfied sliding direction of sweeping of its sense of displacement; That is to say, the X-axis coordinate of supposing contactor control device is by increasing progressively from left to right, and Y-axis coordinate is while increasing progressively from top to bottom, after above-mentioned two object positions are calculated, can further judge that whether primary importance information X-axis coordinate Xa+1 is large compared with the Building X mark Xa of next record positional information, if be just defined as edge when this condition meets in the lump, sweep sliding gesture, to avoid the erroneous judgement false touch of gesture in the other direction.
In like manner, coordinate and consult shown in Fig. 3 B again, if read in the first stroke positional information S10 in the t1 time, and judgement falls into S11, S12 after nearly left first area D_left, in the t2 time, read again next record positional information S121, judge afterwards the displacement difference of two positional informations, judge whether this displacement difference surpasses default displacement S122; If so, be judged as edge and sweep sliding gesture S123; Otherwise, read in again next record positional information and the first stroke positional information is compared displacement difference, until in Preset Time, do not have the displacement difference of arbitrary positional information and the first stroke positional information to be greater than this preset value S124, then by rearmost position information output S125.The same ground, this left first area D_left standard is for judgement is by sweeping from left to right sliding gesture, therefore can judge that whether the first stroke positional information X-axis coordinate Xb is little compared with the Building X mark Xb+1 of next record positional information, if be just defined as edge when this condition meets in the lump, sweep sliding gesture, to avoid the erroneous judgement false touch of gesture in the other direction.
Moreover, coordinate again shown in Fig. 3 C, if read in the first stroke positional information S10 in the t1 time, and determine and to fall into S11, S12 after the D_up of first area, S13, in the t2 time, read again next record positional information S131, calculate afterwards the displacement difference of these two positional informations, judge whether this displacement difference surpasses preset value S132; If so, be judged as edge and sweep sliding gesture S133; Otherwise, read in again next record positional information and the first stroke positional information is compared displacement difference, until in Preset Time, do not have the displacement difference of arbitrary positional information and the first stroke positional information to be greater than this preset value S134, then by rearmost position information output S135.Because Fig. 3 C illustrates this contactor control device 10 that first area D_up on is provided, can standard judgement sweeping from top to bottom sliding gesture, therefore can judge that whether the first stroke positional information Y-axis coordinate Yc is little compared with the Building Y mark Yc+1 of second place information, if be just defined as edge when this condition meets in the lump, sweep sliding gesture, to avoid the erroneous judgement false touch of gesture in the other direction.
Because above-described embodiment whether surpasses preset value with displacement difference judgement, mainly can more general gesture translational speed fast because sweep sliding gesture, therefore another preferred embodiment of the present invention directly judges the translational speed of object and whether meets preset value, usings as the judgement basis that determines whether to sweep sliding gesture; That is to say, after reading several information, judge whether its first stroke positional information drops in this first area, and the translational speed that judges this object according to these several positional informations; If the first stroke positional information drops on this first area and this translational speed while being greater than a preset value, the action that determines this object is that edge cunning is swept gesture.
Moreover, above-described embodiment is only established single displacement and is judged, correct judgment is non-the best still, therefore sweep the correctness of sliding gesture for improving again judgement edge, refer to shown in Fig. 4, point in carrying out edge and sweep when sliding, finger in slip the speed in nearly contactor control device 10 outsides necessarily near inner side speed be low, therefore the present invention is further subdivided into first area D a plurality of D1 ~ D3 of subregion side by side from outside to inside, and corresponding a plurality of subregion D1 ~ D3 is preset with different preset value (R1 ~ R3); Among a plurality of subregions, the corresponding preset value of subregion away from this contactor control device lateral margin is greater than the corresponding preset value near the subregion of this lateral margin, and the preset value of a plurality of subregion D1 ~ D3 increases (R1<R2<R3) from nearest contactor control device one lateral margin according to sweeping sliding direction.Therefore, first fall within wherein object position and the next record object positional distance of a subregion D1, D2, D3, must surpass displacement corresponding to this subregion, be just judged as edge and sweep sliding gesture.
Shown in Fig. 5 A, near in the right first area D_right on the right side of this contactor control device 10 by outside to inner side three subregion D1 ~ D3 side by side, respectively to there being three groups of preset values (R1 ~ R3); So when first finger falls within subregion D1, the control circuit of this contactor control device 10 is to read several positional informations sweep time (about 12.5ms of t1 ~ t2 time), the first stroke positional information and after displacement difference d11 between rear each positional information as calculated, compare with the preset value (R1) of subregion D1 again, judge whether to exceed this preset value (R1), if be judged as edge, sweep sliding gesture (d11>R1).
Again as shown in Figure 5 B, when if first finger falls within subregion D2, the control circuit of this contactor control device 10 is to read continuously several positional informations sweep time, the first stroke positional information and after the displacement difference d12 between rear each positional information as calculated, compare with the preset value (R2) of D2 subregion again, whether exceed this preset value displacement R2, if be judged as edge, swept sliding gesture (d12>R2).
Again as shown in Figure 5 C, when if first finger falls within subregion D3, the control circuit of this contactor control device 10 reads several positional informations continuously with the scan period, the first stroke positional information and after displacement difference d13 between rear each positional information as calculated, compare with the preset value R3 of subregion D3 again, whether exceed this preset value R3, if be judged as edge, swept sliding gesture (d13>R3).
From Fig. 4 A to Fig. 4 C, if user carries out edge really, sweep and slide while doing, finger is during sweeping cunning, speed at D1 ~ D3 subregion is really different, known identical sweep time to capture several positional informations, in the displacement difference of nearly outside subregion, compared with the displacement difference of inner side subregion, be short; Therefore, the present embodiment is further further distinguished into a plurality of subregions by first area, and presets not coordination preset value respectively, therefore can effectively improve the correctness that sliding gesture is swept at judgement edge, reduces erroneous judgement.
In sum, because first area of the present invention and this contactor control device side keep a distance, can make exhausted major part is that the finger of sweeping sliding gesture falls into this first area, improve the condition that the first stroke positional information falls into this first area, solve and have high low head to cause read the first stroke positional information cannot fall into the problem of first area because contactor control device is assembled to casing; Then, the present invention is as long as judgement the first stroke positional information and other positional information have displacement difference, and in a Preset Time, obtain with the displacement difference of a positional information wherein and surpass preset value, or the object translational speed of judging according to a plurality of positional informations is greater than preset value, can be judged as edge and sweeps sliding gesture; Wherein, the preset value of judgement displacement difference according to generally sweep sliding gesture by this first area sweep slip velocity degree and this contactor control device is established default sweep time, therefore when judgement displacement difference is greater than this preset value, it is zero that i.e. representative falls into the finger initial velocity of this first area non-, and meet the digit speed that sliding gesture is swept at edge, and be judged as edge, sweep sliding gesture; Therefore, the present invention can correctly identify edge and sweep sliding gesture, therefore can be applicable to as on the contactor control devices such as Trackpad (Touch Pad) or touch control screen (Touch screen).
Although the present invention discloses as above with preferred embodiment, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, so protection scope of the present invention should be as the criterion with claim limited range.
