In embodiments of the present invention, respectively by the infrared touching signals parameter value of each light path in each scanning direction with it is pre-
If parameter reference value carry out difference operation, when its difference is more than certain parameter threshold, determine the light path to block light path.
Fig. 6 is the infrared touching signals ginseng of light path in scanning direction shown in a kind of Fig. 5-a provided in an embodiment of the present invention
Number histograms, show infrared touching signals parameter value in light path 5-9, parameter reference value q1 and parameter threshold in Fig. 5-a
Δ q, wherein, when the infrared touching signals parameter value of certain light path is more than parameter threshold Δ q with the difference of parameter reference value q1, will
The light path is defined as blocking light path.That is, when the infrared touching signals parameter value of certain light path is less than parameter q2, should
Light path is defined as blocking light path.As shown in fig. 6, in first scanning direction on long side, the infrared touching signals parameter of light path 6-8
Value blocks light path as first scanning direction on long side less than parameter value q2, then using light path 6-8.Based on same principle,
In scanning direction shown in Fig. 5-b, light path 4-7 is determined to block light path；In the scanning direction shown in Fig. 5-c, light path is determined
4-6 is to block light path；In the scanning direction shown in Fig. 5-d, light path 3-5 is determined to block light path.
It is determined that each scanning direction block light path after, light path is blocked to block with first in each scanning direction
The beginning boundary in region, the last item block the termination border that light path is occlusion area, and then in determining each scanning direction
Occlusion area.By taking Fig. 5-a as an example, in first scanning direction on long side, the beginning boundary of occlusion area is light path 6, is blocked
The termination border in region is light path 8, then the region between light path 6 and light path 8 is the occlusion area of first scanning direction,
As shown in the dash area in Fig. 7-a, as finger blocks the coverage extent difference of light path to each bar so that each bar
The infrared touching signals parameter value for blocking light path is different, in embodiments of the present invention, to block infrared touch-control minimum in light path
Infrared touching signals parameter value of the signal parameter value as occlusion area.For example include light path in the occlusion area shown in Fig. 6
6th, 7 and 8 this three block light path, the infrared touching signals parameter value for blocking light path 7 is the minimum of first scanning direction on long side
Signal parameter value min, then will block the infrared touching signals ginseng of the infrared touching signals parameter value of light path 7 as the occlusion area
Numerical value.Based on same principle, the occlusion area and corresponding occlusion area of determination the other three scanning direction is infrared respectively
Touching signals parameter value.Wherein, the occlusion area of second scanning direction on long side is as shown in the dash area in Fig. 7-b；Minor face
The first scanning direction occlusion area as shown in the dash area in Fig. 7-c；The occlusion area of the second scanning direction of minor face
As shown in the dash area in Fig. 7-d.
After the occlusion area for obtaining each scanning direction, the occlusion area of each scanning direction is overlapped, will be each
The intersection area of the occlusion area of individual scanning direction is used as touch point.Obtain after occlusion area shown in Fig. 7 is overlapped
Intersection area 108 is as shown in Figure 8.Wherein, intersection area 108 be touch point, by the barycentric coodinates of intersection area 108, width and
Coordinate, width and height highly respectively as touch point.In addition, infrared touching signals minimum in each occlusion area are joined
Minimum signal parameter value of the numerical value as touch point.It is easily understood that the minimum signal parameter value of touch point is to touch with described
Touch an infrared touching signals parameter value that there is minimum in all light paths occured simultaneously.
Step S203：According to the minimum signal of each touch point in continuous multiple scan periods before present scanning cycle
The variation tendency of parameter value, determines the output mode of each touch point present scanning cycle Nei, wherein, it is described continuous multiple to sweep
The cycle of retouching includes present scanning cycle.
One scan period refers to the infrared touching signals for having gathered each light path in each scanning direction of infrared touch frame
The cycle of parameter value.During user's Touch screen, as in different time points, finger is dynamic change, therefore
In the different scan periods, in each scanning direction, the infrared touching signals parameter value of each light path is different.For example, when user sends out
When playing touch action, finger moves closer to screen, then the minimum signal parameter value of touch point is gradually reduced；When user abandons touching
During action, finger is gradually distance from screen, then the minimum signal parameter value of touch point gradually increases；When the finger of user hovers over screen
During curtain top, the minimum signal parameter value of touch point floats in certain scope.The embodiment of the present invention combines the touch of user
Custom, considers the output mode that the infrared touching signals parameter value in multiple scan periods determines touch point, below to each
The situation of kind is described separately.
As shown in Figure 1B, as the touch-responsive areas of infrared touch frame have certain height, between finger and screen
Distance it is nearer, finger is higher to ultrared coverage extent, therefore, when the user touches the screen, the minimum signal of touch point
Parameter value can be gradually reduced, and based on the principle, can determine user by the variation tendency of the minimum signal parameter value of touch point
Touch be intended to.
It is pointed out that when scanning direction only one of which, then the minimum signal parameter value of the scanning direction is touched
The minimum signal parameter value of point；When the quantity of scanning direction is multiple, need the minimum signal parameter of multiple scanning directions
Value is compared, using minimum of a value therein as touch point minimum signal parameter value.In embodiments of the present invention, in order to describe
Succinctly, illustrated with the variation tendency of the infrared touching signals parameter value of light path in a scanning direction.
Fig. 9 is the infrared touching signals parameter Nogata of light path in a kind of multiple scan periods provided in an embodiment of the present invention
Figure.Figure 9 illustrates infrared touching signals ginseng of a plurality of light path in a scanning direction in four scan period T1-T4
Numerical value, wherein scan period T4 are present scanning cycle, and the scan period, T1-T4 was continuous in time.As shown in figure 9, in scanning
In cycle T 1-T4, the infrared touching signals parameter value of light path 3 is minimum, therefore can be by the infrared touching signals parameter value of light path 3
As the minimum signal parameter value min of corresponding touch point.Due in scan period T1-T4, the minimum signal parameter of touch point
Value min is gradually reduced, it is thus determined that the output mode of the touch point is touch mode.
Touch-responsive threshold value t1 is additionally provided with a kind of preferred embodiment of the invention, specially：When touch point is continuous
Minimum signal parameter value in multiple scan periods is gradually reduced, and the minimum signal parameter value in present scanning cycle is less than
During default touch-responsive threshold value t1, determine that the output mode of the touch point is touch mode.It is provided with touch-responsive threshold
The purpose of value t1 is, only when the distance between the finger and screen of user is near enough, just to determine the output mould of the touch point
Formula is touch mode, prevents erroneous judgement.
The judgement mechanism of the technical program is, when user wants Touch screen, finger is gradually leaned on by the top of screen
Nearly screen in the process, have passed through multiple scan periods until clicking the relevant position of screen, due to user finger by
It is gradually close to screen, therefore the minimum signal parameter value of touch point is gradually reduced.In addition, it is handled sensitive in order to prevent, only
The touch-responsive of system is triggered when the distance between the finger and screen of user is near enough, thus it is pre- in embodiments of the present invention
If touch-responsive threshold value t1.
Certainly another kind of situation is also likely to be present, when user's finger is close to screen, the position that finger will be touched is found
Put the position for wanting to touch with user not being inconsistent, now finger is lifted on screen.Equally can be to phase during finger is lifted
Answer light path infrared ray cause it is a certain degree of block, if in this case system output touch-responsive obviously can cause miss
Triggering.
It is for this problem, in embodiments of the present invention, described according to continuous multiple scannings before present scanning cycle
In cycle, the minimum signal parameter value of each touch point, determines the output mode of each touch point present scanning cycle Nei, also wraps
Include：When the arbitrary touch point in present scanning cycle minimum signal parameter value within continuous multiple scan periods gradually
During increase, determine that the touch point is Null Spot.
Figure 10 is that the infrared touching signals parameter of light path in another kind of multiple scan periods provided in an embodiment of the present invention is straight
Fang Tu.Figure 10 illustrates infrared touch-control letter of a plurality of light path in a scanning direction in four scan period T5-T8
Number parameter value, wherein scan period T8 are present scanning cycle, and the scan period, T5-T8 was continuous in time.As shown in Figure 10, exist
In scan period T5-T8, the infrared touching signals parameter value of light path 3 is minimum, therefore can be by the infrared touching signals ginseng of light path 3
Minimum signal parameter value min of the numerical value as corresponding touch point.Due in scan period T5-T8, the minimum signal of touch point
Parameter value min gradually increases, it is thus determined that the touch point is Null Spot.
Lift response threshold value t2 is additionally provided with a kind of preferred embodiment of the invention, specially：When touch point is continuous
Minimum signal parameter value in multiple scan periods gradually increases, and the minimum signal parameter value in present scanning cycle is more than
During default lift response threshold value t2, determine that the touch point is Null Spot.Wherein, the purpose for arranging lift response threshold value t2 exists
In only just determining the touch point when the distance between the finger and screen of user is remote enough for Null Spot, prevent from judging by accident.
In embodiments of the present invention it is contemplated that the height of infrared transmitting tube and infrared receiving tube is to infrared touching signals
The impact of parameter value, therefore distance between finger and screen can be determined by the size of infrared touching signals parameter value, and then
The suspension triggering pattern of touch point is judged.
Figure 11 is that the infrared touching signals parameter of light path in another kind of multiple scan periods provided in an embodiment of the present invention is straight
Fang Tu.Figure 11 illustrates infrared touch-control letter of a plurality of light path in a scanning direction in four scan period T9-T12
Number parameter value, wherein scan period T12 are present scanning cycle, and the scan period, T9-T12 was continuous in time.As shown in figure 11,
In scan period T9-T12, the infrared touching signals parameter value of light path 3 is minimum, therefore can be by the infrared touch-control letter of light path 3
The minimum signal parameter value min of number parameter value as corresponding touch point.Due in scan period T9-T12, the minimum of touch point
Signal parameter value min is in all the time between touch-responsive threshold value t1 and lift response threshold value t2, thus may determine that the touch point
Output mode be suspension triggering pattern.Further, since the usual only one of which touch point of suspension triggering pattern, therefore in the present invention
In embodiment, suspension triggering pattern must also meet condition in scan period T9-T12, and the quantity of touch point is one.
The judgement mechanism of the technical program is, after the finger of user hovers a short time in the top of screen, to judge
Corresponding touch point is suspension triggering pattern, i.e., when the minimum signal parameter value of the arbitrary touch point in present scanning cycle is described
When in continuous multiple scan periods in certain domain of walker, determine that the output mode of the touch point is the triggering that suspends
Pattern.
It is pointed out that in embodiments of the present invention for convenience of description, with 4 scan periods to triggering pattern, nothing
Effect point and suspension triggering pattern are judged that those skilled in the art can also according to actual needs by continuous multiple scannings
Cycle set is other quantity, and which should fall under the scope of the present invention.
In sum, present invention thought can be summarized simply as follows three kinds of situations：First, when in present scanning cycle
The minimum signal parameter value of arbitrary touch point when being gradually reduced within continuous multiple scan periods, determine the touch
The output mode of point is touch mode；Second, when the minimum signal parameter value of the arbitrary touch point in present scanning cycle is in institute
State when gradually increasing in continuous multiple scan periods, determine that the touch point is Null Spot；3rd, when in present scanning cycle
Arbitrary touch point minimum signal parameter value within continuous multiple scan periods in certain domain of walker when,
Determine the touch point output mode be suspension triggering pattern.
Wherein, the processing method when embodiment of the present invention is unsatisfactory for above-mentioned three kinds of situations to infrared touching signals parameter value is not
It is specifically limited, those skilled in the art can carry out relative set according to actual conditions, without departing from foregoing invention thought
Under the premise of, which should fall under the scope of the present invention.For example, for the first situation, when judging touch point most
When small-signal parameter value is gradually reduced but the scan period is also not reaching to the quantity for requiring, then not output point, i.e., as this track
Without point；For second situation, when the minimum signal parameter value of touch point gradually increases, but the scan period is also not reaching to require
Quantity when, then the touch point of a nearest scan period before exporting this track；For the third situation, when continuous many
In the individual scan period, the minimum signal parameter value of touch point is all higher than or equal to t1, and is less than or equal to t2, but Current Scan
When in cycle, the quantity of touch point is two or more, it is determined that all of touch point is touch mode.
Figure 12 is the process flow schematic diagram of another kind of infrared touch panel touching signals provided in an embodiment of the present invention,
As shown in figure 12, the method is further comprising the steps of on the basis of embodiment illustrated in fig. 2.
Step S204:According to the output mode of the touch point, corresponding responsive state is exported on a display screen.
In implementing, touch point information can be uploaded to according to form (x, y, width, height, mode) upper
Machine, wherein x, coordinates of the y for touch point, width of the width for touch point, height of the height for touch point, mode are touch
The output mode of point.Wherein, suspension reserve mode is defined as when being 0 by mode, mode is defined as suspension triggering pattern when being 1,
Mode is defined as touch mode when being 2.
Host computer is parsed after receiving the packet of upload, if the pattern of touch point is 1, in the corresponding positions of screen
Put output mouse to suspend response, the relevant position refers to the position matched with the coordinate of touch point, width and height；If touching
The pattern of point is 0 or 2, then the relevant position output in screen is touched and clicks on response.
As shown from the above technical solution, in embodiments of the present invention in view of infrared transmitting tube and the height of infrared receiving tube
Impact to infrared touching signals.Due to the change of the infrared touching signals parameter value of touch point within continuous multiple scan periods
