Specific embodiment
Here in detail explanation will be executed to exemplary embodiment, its example is illustrated in the accompanying drawings.Explained below is related to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the present invention.On the contrary, they be only with such as appended
The example of the consistent apparatus and method of some aspects being described in detail in claims, the present invention.
Fig. 1 is a kind of touch-responsive method flow diagram of the infrared touch panel according to an exemplary embodiment.As Fig. 1
Shown, the touch-responsive method of this infrared touch panel may comprise steps of.
In step s 110, determine the touch point carrying out touch operation in infrared touch panel by noctovisor scan.
During infrared touch panel runs, by the scan period one by one, infrared touch panel is carried out again and again infrared
Line scans, to perceive in infrared touch panel touch operation in the touch point of every scan cycle.
It should be understood that in infrared touch panel, being accordingly equiped with emission lamp and receive lamp, being lighted by emission lamp
With the reception receiving lamp, infrared ray net is formed on infrared touch panel, and then perceives the touch point of touch operation.
Specifically, Fig. 2 is a kind of structural representation of the infrared touch panel according to an exemplary embodiment.As figure
Shown in 2, the outward appearance of infrared touch panel is a rectangular configuration, is made up of long side and minor face.Long when including a long edge emitting
110 and a long receiving while 120, minor face includes a minor face transmitting side 130 and a short receiving while 140.Send out on long side
Penetrate and be equiped with some emission lamps in side 110 and minor face transmitting side 130, accordingly in long receiving while 120 and short receiving while 140
Correspondence is equiped with some reception lamps.It is made to form transmitting according to one-to-one mode by controlling these emission lamps and reception lamp
It is right to receive, and the infrared ray being respectively turned on every a pair of emission lamp and reception lamp in a certain order and carrying out scan cycle is swept
Retouch.By detecting every a pair of emission lamp and receiving whether the infrared ray between lamp is blocked, to judge to carry out in infrared touch panel
Touch operation in the touch point of present scanning cycle.
In the step s 120, judge that whether touch point is the touch first point of touch operation.
Touching first point is the touch point detecting first in infrared touch panel touch operation.Carry out infrared ray to sweep
The touch point retouching and determine is it may be possible to touch first point it is also possible to the other touch points touching during keeping of touch operation.
By abovementioned steps 110, the touch operation by being carried out determines and obtains its touch point in scan cycle, now need into
Whether row touch point is the identification touching first point, and then ensures the accuracy that the touch point subsequently being carried out responds.Touch operation
Touch keep during, some shakes of the more or less generation on infrared touch panel of touch operation, and it is whole for touching first point
The touch point that individual touch contacts infrared touch panel at first and is detected during keeping.
During noctovisor scan is carried out again and again to infrared touch panel by the scan period one by one, sentence
Whether disconnected touch point is to touch implementing of first point, can be first in infrared touch panel by detecting a touch operation
Touch point is to touch first point it is also possible to pass through to carry out touching sentencing of first point with quantity touch point is detected in scan cycle
Disconnected, can also in other way touch point be carried out touching the judgement of first point.
It is previously provided with initialized touch first point in infrared touch panel, touch operation process is being carried out to infrared touch panel
In, when determining the touch point that certain scan cycle detects is to touch first point, then this touch point is modified to touch first point,
And then the touch-responsive pattern that this touch operation is carried out with touch-responsive is determined by the revised first point that touches, thus with
The new first point that touches determines the touch-responsive pattern of touch operation it is ensured that touch operation is carried out with the accuracy of touch-responsive.
For example, only have 1 touch point p (x1, y1) in current infrared touch panel, before there is touch operation, the touch first point p0 of acquiescence
Coordinate position be (x0, y0).When determining p (x1, y1) for first point, then revise and touch first point p0 coordinate position, even if x0
=x1, y0=y1.
When the touch point in infrared touch panel is not to touch first point, then determined to tactile according to this touch point and touch first point
Touch the touch-responsive pattern that operation carries out touch-responsive.
In step s 130, the touch first point in relative touch operation determines that touch-responsive sensitivity is fitted with touch operation phase
The touch-responsive pattern answered.
During touch operation, shaken due to more or less, the touch operation that infrared touch panel detects is swept in difference
The touch point position retouching the cycle differs, if being identified one by one responding according to these touch point positions, may be because
In target zone, do not respond mistake for the touch point position that certain scan period recognizes.Therefore, it is necessary to according to touch
Operation adjustment touch-responsive pattern, and then with specific touch-responsive pattern, touch operation is responded, realize grasping to touching
The fault-tolerant processing made, improves the accuracy of touch-responsive.
For example, Fig. 3 is to send out in the one click operating process in the infrared touch panel according to an exemplary embodiment
Structural representation during raw shake.After the different scan periods carries out noctovisor scan, due to shaking, determine and click on
Touch point during whole operation for the operation is t1, t2.
Again for example, Fig. 4 is in the infrared touch panel according to an exemplary embodiment when once writing operating process
Structural representation.Due to writing operation amplitude less, after the different scan periods carries out noctovisor scan, determine and click on
Touch point t1, t2, t3 during whole operation is also relatively close for operation.
Obviously, write under operation, in infrared touch panel under the different scanning cycle in the clicking operation and Fig. 4 in Fig. 3
The touch point detecting is similar to, but in Fig. 3 click on operating process in multiple touch points relatively close be due to click on
Operation occurs shake to lead to, and is desirable to avoid as far as possible；And multiple touch points of writing in Fig. 4 in operating process are relatively close
Write operation amplitude less and lead to.Thus, when the multiple touch points in different scanning cycle detection to infrared touch panel
Relatively near when, just cannot be distinguished by carrying out during touch operation writing operation and be also by clicking operation.
For example, Fig. 5 is to send out in the one click operating process in the infrared touch panel according to an exemplary embodiment
The structural representation of raw shake.Clicking operation position range be rectangle frame 100 in region, continuous 5 scan period t1,
Clicking operation is detected in t2, t3, t4 and t5 and there is touch point in infrared touch panel.Due to shaking, this 5 scanning weeks
The touch point position that phase detects is all different, and the touch point that scan period t3 detects floats to clicking operation position range
Outward, if being identified one by one responding according to these positions, will be considered that the touch point that scan period t1, t2 detect is to point
Hit the one click action of operating position scope, and the touch point that scan period t4, t5 detect is to clicking operation position model
Another click action enclosed, significantly different with actual touch operation.Thus easily producing touch-responsive mistake, reducing and touching
The accuracy of response.
Preset multiple touch-responsive patterns that touch operation is responded in infrared touch panel, to be adapted to infrared touching
Touch the touch-responsive demand in screen.The sensitivity that different touch-responsive patterns respond to touch operation is different, thus according to touch
Touch first point during operation, chooses the touch-responsive pattern that touch-responsive sensitivity is adapted with touch operation, and then to touch
The touch point that in operation, subsequent scan period detects carries out touch-responsive.
In one exemplary embodiment, touch-responsive pattern includes clicking operation pattern and write mode.Clicking operation
The touch-responsive sensitivity of pattern is relatively low, the deviation that staff is clicked on and shake can be carried out fault-tolerant, thus press in length etc.
Certain deviation can be tolerated during operation, prevent from misidentifying；The touch-responsive sensitivity of write mode is of a relatively high, can be rapid
Delicately touch operation is responded such that it is able to accurately follow the tracks of the touch point of touch operation, in identification infrared touch panel
Write operation.
In step S140, according to touch-responsive pattern and touch point, carry out the response of touch operation.
After determining touch-responsive pattern, the touch point in infrared touch panel is carried out touch according to touch-responsive pattern and ring
Should.
By method as above, according to the touch first point in touch operation, determine touch-responsive sensitivity and touch
The touch-responsive pattern that operation is adapted, and then according to touch-responsive pattern, the touch of touch operation in infrared touch panel is clicked through
Row touch-responsive.Due to touch-responsive pattern suitably can be chosen, thus automatically adjusting according to the difference of touch operation mode
Touch operation is carried out with the sensitivity of touch-responsive, substantially increases the accuracy of touch-responsive.
Fig. 6 is the detailed description to step S130 according to an exemplary embodiment.As shown in fig. 6, this step
S130 may comprise steps of.
In step S131, relative touch first point determines the distance of touch point and touches duration.
The distance of touch point is touch point and touches the location interval between first point.The time of a length of touch operation during touch
Length, i.e. time interval between touch point and touch first point.
During a touch operation of infrared touch panel, when touch point be not touch first point when, obtain touch point with
Touch location interval and the time interval of first point.
For example, Fig. 7 is during a touch operation process in the infrared touch panel according to an exemplary embodiment
Structural representation.During touch operation, touch point that present scanning cycle detects is t3, the touching of whole touch operation
Touch a little be t1, t2, t3, touchs first point be t1, therefore the distance of touch point t3 be touch point t3 and touch first point t1 between away from
From the as △ t of in figure；Touch duration to be touch point t3 and touch the time interval between first point t1.
In step S132, judge whether distance less than default response judging distance, and touch duration to be less than default response
Judge the touch time, obtain judged result.
Response judging distance and response judge that the touch time all pre-sets.Distance to touch point and default response
With default response, judging distance, the touch duration of touch point judge that the touch time carries out size judgement respectively, be met distance
Less than default response judging distance and touch duration and be less than default response and judge the touch time, and it is unsatisfactory for distance less than presetting
Respond judging distance and touch the judged result that duration judges the touch time less than default response.And then judged according to judged result
The touch-responsive sensitivity being adapted with touch operation, chooses corresponding touch-responsive pattern.
Fig. 8 is touch-responsive during a touch operation process in the infrared touch panel according to an exemplary embodiment
The structural representation of mode decision.In touch operation, touch first point is t1, by touching to touch point in this touch operation
Touch duration and distance carries out dual restrictive condition judgement.When touch point is in broken circle tn, and touch duration less than response judgement
Touch time T, then touch point meet dual restrictive condition；If touch point is outside broken circle tn, or touch duration not less than response
Judge touch time T, then touch point is unsatisfactory for dual restrictive condition.
In step S133, if the determination result is YES it is determined that touch operation corresponding touch-responsive pattern is to click on behaviour
Operation mode.
When the distance of touch point is less than default response judging distance, and touch duration is less than default response and judges the touch time
When, because the touch duration of touch operation is shorter, and the skew of touch point position is less, and the distance of touch point is likely to click on behaviour
Shake is occurred to cause when making, because when carrying out writing operation, the distance of general touch point is all larger, on infrared touch panel
Touch sliding time relatively long, therefore touch operation be clicking operation probability bigger, determine that touch-responsive pattern is
Clicking operation pattern, and then according to clicking operation pattern, touch operation is responded, such as ignore current touch point position, still
Touch-responsive is carried out with the position touching first point, improves the accuracy of touch-responsive.
Fig. 9 is fault-tolerant realization during a touch operation process in the infrared touch panel according to an exemplary embodiment
Structural representation.In touch operation C, touch first point is t1, in touching the scan period after first point t1, detects
Touch point be t2, t3, t4, because touch point t2, t3, t4 are all in broken circle tn, meet the distance limit condition of touch point,
And touch duration (touch point t4 and the time interval touching first point t1) and judge touch time T less than response, touch point t2, t3,
T4 is likely to touch operation operation and occurs shake to cause, it is thus determined that the touch-responsive pattern of touch operation C is to click on
Operator scheme, to touch point t2, t3, t4 still with touch first point t1 position carry out touch-responsive, it is to avoid because touch point t2, t3,
T4 is different and respond mistake from the position touching first point t1, realizes carrying out fault-tolerant response to touch operation.
For example, the position coordinateses of current touch point p1 are (x1, y1), and the coordinate touching first point p0 is (x0, y0), initialization
(flag=1 is in correction state to the response position of touch point to point corrected parameter flag=1；Flag=0 represents to touch point
Response position is not in correction state), presetting response judging distance is d, and default response judges the touch time for t.Touch operation
Touch duration L<T, touch point p1 apart from D<d.Now show that the touch duration of touch operation is shorter, and touch operation touch
Touch the skew of position less it is likely to occur shake to cause during clicking operation.Accordingly, it is determined that touching to touch operation
The touch-responsive pattern of response is clicking operation pattern, and revises the response position of touch point, to touch first point p0's (x0, y0)
Position carries out touch-responsive.
In step S134, if judged result is no it is determined that touch operation corresponding touch-responsive pattern is to write mould
Formula.
When judged result is that the distance being unsatisfactory for touch point is less than default response judging distance and touches duration less than default
Response is when judging the touch time, and show touch operation touches that duration is longer or offset distance of touch operation is larger or tactile
That touches operation touches that duration is longer and offset distance of touch operation is larger.Because the touch duration of clicking operation is generally shorter,
The touch duration of therefore touch operation is longer frequently not to carry out clicking operation；The skew of touch point position is larger to be not generally a little
Hit generation shake during operation and cause, it is more likely that carrying out writing operation, it is thus determined that touch-responsive pattern is write mode,
Touch-responsive is carried out to touch operation with higher touch-responsive sensitivity, accurately follows the tracks of the touch point of touch operation, such as to work as
The coordinate position of front touch point carries out touch-responsive.
For example, the position coordinateses of current touch point p1 are (x1, y1), and the coordinate touching first point p0 is (x0, y0), initialization
(flag=1 is in correction state to the response position of touch point to point corrected parameter flag=1；Flag=0 represents to touch point
Response position is not in correction state), presetting response judging distance is d, and default response judges the touch time for t.Touch point p1
Location interval D>D, shows that the touch point position skew of touch operation is larger, frequently not because clicking operation occurs shake to produce
, and it is more likely that carrying out writing the movement in infrared touch panel during operation.Accordingly, it is determined that touch-responsive pattern is to write mould
Formula, makes initialization points corrected parameter flag=0, need not revise the position of current touch point, i.e. the position of touch point p1 (x1, y1)
Carry out touch-responsive.
By method as above, when touch point is not to touch first point, the distance according to touch point and pre-setting
Response judging distance, touch point touch duration and response judge touch duration judged result, determine the sound of touch operation
Answer pattern, and then touch-responsive is carried out to touch operation according to the touch-responsive pattern determining, improve and touch operation is carried out
The accuracy of touch-responsive.
Figure 10 is the detailed description to step S120 according to an exemplary embodiment.Touch point is a scanning week
The touch point that phase determines, as shown in Figure 10, this step S120 may comprise steps of.
In step S121, judge that touch operation whether there is touch point in the previous scan period of this scan period,
Obtain judged result.
Noctovisor scan is carried out again and again to infrared touch panel by the scan period one by one, to touch operation
Touch point carry out detection identification.In the touch point identification process to touch operation, each scan period of infrared touch panel
The position of corresponding touch point, or there is not the situation of touch point.
Touching first point is in the touch point detection identification process to touch operation, detects the presence of the continuous scanning of touch point
The touch point that in cycle, first scan period detects.In each scan period, judge there is sweeping of touch point place
The previous scan period retouching the cycle whether there is touch point, and then judges whether the touch point in each scan period is tactile
Touch first point.
For example, in the touch point identification process to touch operation, continuous 5 scan periods are respectively t1, t2, t3, t4
And t5, scan period t1, t2 and t3 all do not recognize touch point, scan period t4 and t5 recognize touch point be respectively p4 and
p5.Thus recognize in the previous scan period t3 of scan period t4 that touch point p4 is located and there is not touch point, thus judge
Touch point p4 is to touch first point；And there is touch point p4 in the previous scan period t4 of scan period t5 that touch point p5 is located,
Thus judge that touch point p5 is not to touch first point.
In step S122, determine according to judged result whether the touch point during scan period is to touch first point.
By method as above, touch point situation detected according to each scan period, determine in touch operation
Touch first point, and then on the basis of this touch first point, determine the touch-responsive pattern of touch operation, improve and touch operation is entered
The accuracy of row touch-responsive.
Figure 11 is a kind of touch-responsive method flow diagram of the infrared touch panel according to an exemplary embodiment.Same
In scan period, the quantity of touch point is multiple, as shown in figure 11, in the touch-responsive method of the corresponding infrared touch panel of Figure 10
After S110 step, can also comprise the steps.
In step S310, determine that touch operation corresponding touch-responsive pattern is write mode.
In some scan period, the quantity recognizing the touch point of touch operation is multiple, and during touch operation, leads to
Chang Buhui carries out clicking operation with the touch operation of multiple touch points form to infrared touch panel, so will lead to infrared touch panel no
Method response identification；And it is more likely that multi-user is carrying out writing operation, it is thus determined that the touch-responsive pattern pair with write mode
Touch operation carries out touch-responsive.
In step s 320, according to write mode, the position according to touch point carries out the response of touch operation.
By method as above, it is multiple when detection recognizes touch operation in the touch point quantity of synchronization
When, it is no need for judging whether touch point is to touch first point, directly determine that touch-responsive pattern is write mode, and then according to writing
Pattern carries out touch-responsive to touch operation, prevents from still so that clicking operation pattern is identified, mistake occurring during multiple point touching
By mistake, improve the efficiency that touch operation is carried out with touch-responsive.
