Embodiment
Below with reference to accompanying drawings and in conjunction with specific embodiments of the invention technical characterictic of the present invention, characteristics and beneficial effect are described in detail.In accompanying drawing, same or analogous Reference numeral is used for illustrating same or analogous technical characterictic.
Fig. 1 illustrates the structured flowchart of capacitance type input mechanism according to the preferred embodiment of the invention.Capacitance type input mechanism 100 comprises capacitance plate 101, signal analysis unit 102, screening area definition unit 103, assessment unit 104 and effective touch point determining unit 105.
102 pairs of touch signals from capacitance plate of signal analysis unit are analyzed, and position to touching input the position of determining the touch point.As is known to persons skilled in the art, by setting the threshold value of touch signal, at first signal analysis unit 102 can be deleted and not satisfy the touch signal that threshold value requires when analyzing from the touch signal of capacitance plate, only determines the touch point according to satisfying the touch signal that threshold value requires.By setting threshold, various touch signals are carried out preliminary screening, can reduce the data processing amount of whole capacitance type input mechanism, improve operating rate and the response accuracy of input media.102 pairs of definite touch points of signal analysis unit are further analyzed a plurality of eigenwerts that characterize respectively the different input feature vectors of touch input that obtain in touch signal.The feature of touch signal comprises, such as but not limited to, the signal intensity of touch signal, the stability of signal intensity, and the stability of touch signal position and area of touch area etc.It will be appreciated by those skilled in the art that, here related signal intensity can be for example the maximum of intensity Max of touch signal, the stability of signal intensity can be for example the variation DeltaM of the maximum of intensity of touch signal in continuous coverage, the touch area area is for example the area A rea of the occupied horizontal ordinate scope in touch point and ordinate scope, the stability of touch signal position, or can be described as central point stability, can be for example the change in location DeltaP of touch point centre coordinate in continuous coverage.
According to a preferred embodiment of the invention, after determining the touch point according to the threshold value of setting and analyzing the eigenwert of these features of touch point touch signal, feature to the touch signal of diverse location touch point on the capacitance plate screen is weighted the assessed value that assessment obtains touch signal, determine effective touch point in the touch point according to the size of assessed value, and the user is touched input make correct response.
Screening area definition unit 103 is used for the position of definition screening area on touch-screen and is different from the weight of touch signal weight outside screening area for the touch signal setting in screening area.By the feature for touch signal in dissimilar screening area, different weights is set, can calculates the weighting assessed value of each touch point touch signal, as the foundation of the effective touch point of Analysis deterrmination from a plurality of touch points.
According to one embodiment of present invention, screening area definition unit 103 can define according to the current application environment of capacitance plate in capacitance type input mechanism 101 position of using screening area.For example, be appreciated that when a certain zone of capacitance plate 101 shows keyboard, the finger touch that appears in this zone will be effective touch, and in this zone, the palm touch is likely maloperation and appear at.Therefore, capacitance plate region division that can this keyboard is corresponding is for using screening area.In using screening area, can characterize and touch input is that the eigenwert of finger input is set up and has higher weight, and to touch input be that the eigenwert of palm input is set up lower weight and characterize.For example, the touch area area value in the threshold value suitable with the finger area is set up higher weight, and is set up less weight greater than the touch area value of this threshold value.
Effectively touch point determining unit 105 is used for determining effective touch point according to the assessed value of each touch point.For the example of above-mentioned application screening area, when being input as in using screening area pointed input, because its touch signal has high assessed value, thereby be identified as effective input.If there is in using screening area be input as the palm input time, because of the lower weight of its touch signal eigenwert correspondence, touch signal will have lower assessed value, and then this input will be identified as maloperation.
According to another embodiment of the invention, signal analysis unit 102 can touch according to the position definition of determined touch point the position of screening area and for being in the touch point that touches screening area, the touch signal assessment weight that is different from the outer touch point of screening area is set.In most of applied environments, effectively touching the peripheral region of input, in lower zone, the larger area input such as the palm input would not appear for example.Based on such understanding, can will than the long-pending value of large touching surface, less weight be set in certain area around the touch point, touch input and more easily be identified as maloperation so that appear at larger area around a certain touch point.
Should be appreciated that the technical scheme that above-mentioned two embodiment describe can be used in combination.For example, the position that at first screening area definition unit 103 can use screening area according to the current application environment definition of capacitance plate in capacitance type input mechanism 101, be the outer definition touch screening area position, touch point of application screening area, and each touch point touch signal that is respectively in different screening areas arranges weight.
Fig. 2 illustrates the method flow diagram of determining according to the preferred embodiment of the invention effective touch point.In the capacitance type input mechanism 100 that has as shown in Figure 1, capacitance plate 101 response multiconductor inputs produce a plurality of touch signals.In these contact inputs, some input is effective input, and some input is maloperation.The method according to this invention, weight by touch signal inside and outside the position that defines screening area on capacitance plate 101 and screening area, can be according to the position of touch point, the position of screening area is assessed a plurality of touch points, and determines rapidly and accurately the effective touch signal in described a plurality of touch signals and and then define the effect touch point according to assessed value.Describe method step of the present invention in detail below with reference to Fig. 2.
Step 1, the touch signal of Detection capacitance screen is determined a plurality of eigenwerts of touch point and touch point according to the threshold value of setting.
By the touch signal from capacitance plate is analyzed, can position the touch point that obtains touching input to touching input.In the present invention, according to predefined touch signal threshold value, touch signal is analyzed, removed and do not satisfy the touch signal that threshold value requires, and determine the touch point based on the touch signal that satisfies the threshold value requirement.Further, the touch signal analysis of determined touch point is obtained the eigenwert of each feature that touch signal comprises.The feature of touch signal comprises, such as but not limited to, the signal intensity of touch signal, the stability of signal intensity, and the stability of touch signal position and area of touch area etc.It will be appreciated by those skilled in the art that, here related signal intensity can be for example the peak value of touch point touch signal, the stability of signal intensity can be for example the variation of touch point touch signal peak in continuous coverage, the touch area area is for example the product of the occupied horizontal ordinate scope in touch point and ordinate scope, and the stability of touch signal position can be for example to touch the variation of center point coordinate in continuous coverage.The large I of touch signal eigenwert is used to determine whether each touch point is effective touch point.
The purpose of definition screening area is the eigenwert of each feature of the touch signal of diverse location on screen is arranged different weights.For example by the eigenwert for the touch signal that occurs in the zones of different of capacitance plate screen, weight is set, can calculates the weighting assessed value of each touch point on the capacitance plate screen, and determine exactly effective touch point thus from a plurality of touch points.
According to one embodiment of present invention, can use the position of screening area and for being in the touch point of using screening area, the touch signal assessment weight that is different from the outer touch point of screening area is set according to the definition of capacitance plate current application environment.Fig. 3 illustrates the touch screen zone schematic diagram of the example 1 according to the present invention.Fig. 3 A is a kind of applied environment schematic diagram of capacitance plate, and its applied environment demonstrates to point to write paints regional C, key area D
1-D
6Fig. 3 B illustrates the coordinate schematic diagram of capacitance plate shown in Fig. 3 A.The finger of capacitance plate is write and is painted regional C and can write drawing shape or word, key area D for the user
1-D
6Be used for function button.Write at finger and paint in regional C, the various touch inputs of finger and palm all may occur.Therefore paint regional C for writing, various touch signal eigenwerts can have identical weight, for example are 1.When the user need to input in the key area, generally, the user used light finger touch of key-press zone D
1-D
6Realize input, touch key-press for a long time not, thereby can be with regional D
1-D
6Be defined as the application screening area.Using and characterizing input in screening area is that the touch signal eigenwert of pointing input is set up higher weight.
According to another embodiment of the invention, can touch screening area according to position, the touch point definition of determining in step 1.Fig. 4 illustrates the touch screen zone of the example 2 according to the present invention and uses schematic diagram.In a lot of application of touch screen, only need 1 finger or 2 finger touch screens, as shown in the figure.When the finger touch screen, it is A that finger is felt the zone
1And A
2, palm thoughts and feelings zone, finger below is B
1And B
2Because the palm area is larger, even if palm is unsettled, screen still may be sensed the palm input and maloperation occurs.The user needs the high arm of raising one's hand to avoid palm near screen, for use has brought very large inconvenience for fear of the generation of maloperation.
Occur in finger touch point A in order to eliminate
1And A
2The palm of lower zone touches the maloperation of introducing, can be with the regional B of finger below
1And B
2Be set to touch screening area.The eigenwert that appears at the touch signal feature that characterizes the palm input in the touch signal in this touch screening area can be set up less weight.Can make thus the touch signal that touch to be produced by palm have less assessed value, thereby and this touch signal is left in the basket avoided the generation of maloperation.
According to still a further embodiment, can determine screening area according to the movement tendency of pointing under the position of the finger input of roughly determining and current screen applied environment.Fig. 5 illustrates according to the touch screen zone of the embodiment of the present invention 3 and uses schematic diagram.In Fig. 5, reticulate texture is the basic coordinates structural representation of capacitance plate.In the application that common screen orientation is fixed, be in the game of forward as handwriting input or picture layout, if touch point A
1Centre coordinate be (x
A1, y
A1), can define B so
1The zone is regional for touching screening, and the coordinate range of its directions X is x
A1-j is to x
A1+ j, the coordinate range of Y-direction are y
A1-k is to y
A1-l, j wherein, k is positive number, and k＜l.The size of scope is determined according to actual conditions.The eigenwert that appears at the touch signal feature in this zone is set up higher weight.That is, for example, when occurring in touch point A
1After touch input appear at regional B
1When middle, because the touch signal of this input has high assessed value, the touch point of this input will very likely be identified as effective touch point.
Further, for example, if the game of Chinese chess class, as can be known the finger touch direction may be not only up but also below, so touch point A
1Input screening zone can be defined as B
1And B
2Two zones.The zone B1 as previously mentioned, regional B
2The coordinate range of directions X be x
A1-j is to x
A1+ j, the coordinate range of Y-direction are y
A1+ k is to y
A1+ l, the touch signal feature that appears in these two zones is set up higher weight.
Be appreciated that in most cases the touch direction of finger is confirmable.If applied environment is difficult to determine the direction of user's finger touch, can not define the screening area territory.
In most cases, in the capacitance plate use procedure, appear at simultaneously that in a plurality of touch points on capacitance plate, the highest touch point, position is very likely effective touch point.Based on such understanding, the touch signal feature setting of touch point that can this position is the highest has larger weight.
Step 3 according to the assessment weight of each touch signal, is weighted to the feature of each touch signal the assessed value that assessment obtains each touch point respectively.
Generally, the outer touch point of screening area has predefined weight.After having defined the position and the assessment of the touch signal in screening area weight that has namely defined screening area after the screening area, need to assess all touch points on screen.For example, by the weighting assessed value to the product read group total touch signal of each eigenwerts of all touch signals and respective weights.
Step 4 is determined effective touch point according to assessed value.
By the size of each touch point assessed value relatively, for example touch point of assessed value maximum can be defined as effective touch point.
The present invention will be described below in conjunction with instantiation.Table 1 shows the definition rule of each feature weight of touch signal in each screening area of definition, wherein is listed as I and shows feature that touch signal has and the expression of eigenwert; Row II illustrates the score value that this rule is given each feature; Row III illustrates the relation between threshold value in eigenwert and definition rule; Row IV illustrates feature and concerns actual score value in situation in the eigenwert that satisfies regulation and threshold value; Row V illustrates the product of feature score value and respective weights in the button screening area of the example 1 according to the present invention; Row VI illustrates the product of feature score value and respective weights in the finger below screening area of the example 2 according to the present invention.Should be appreciated that the screening area type definition rule shown in table 1 is schematic but not determinate, those skilled in the art can know the rule of other definition screening areas thus by inference.
For example, embodiment according to the present invention 1, the regional D of Fig. 3 B is corresponding to the key area on Fig. 3 A capacitance plate plane.In the process of determining effective touch point, this key area can be defined as the button screening area.Be appreciated that, appear at effective touch input in regional D and should be the small size contact and by long input of the time of touching, therefore can appear to characterize in the touch signal of each point in the button screening area and touch the larger weight of eigenwert setting that input is the finger input.Particularly, when the maximal value of touch signal greater than predetermined threshold 1 and when the touch area of touch point was suitable with the finger area, the weight of these two features in threshold range was 0.9.the weighting assessment of calculating this touch point touch signal will obtain larger weighting assessed value, thereby this touch point more easily is confirmed as effective touch point, different therewith, when touch in appearing at button screening area input has good central point stability DeltaP＞threshold value 3 and maximal value stability DeltaM＞threshold value 2, for example finger or palm rest on this regional situation, according to rule, the weight of this central point stability in this threshold range be 0.6 and actual score value C2 will reduce according to the linearity that concerns between DeltaP and threshold value 3, the actual score value of maximal value stability also reduces linearity with the relation between DeltaM and threshold value 2.The weighting assessment of calculating this touch point touch signal will obtain less weighting assessed value, thereby this touch point more easily is confirmed as maloperation in a plurality of simultaneous touch points.
Table 1
For example, embodiment according to the present invention 3, the regional B1 of Fig. 4 and B2 are corresponding to the finger lower zone of capacitance plate finger touch point.Be appreciated that after definite finger touch point A1 and A2, appear at finger below large tracts of land touch and input normally maloperation.For this reason, the row IV in table 1 has defined this screening area type.Can find out, when feature touches area greater than threshold value 4, the actual score value of this feature will further reduce with the increase of area, and weight is 0.8; When the eigenwert numerical value relevant with stability was larger, the less and weight of its actual score value only was respectively 0.6 and 0.7.Thereby the touch signal with touch point of such eigenwert is when appearing in regional B1 or B2, more easily is identified as maloperation because the weighting assessed value of touch point is very low.
According to the present invention, by according to user's use habit and the handling characteristics of different application software, to the capacitance plate screen partition, for giving different attributes in different zones, make the valid function or the maloperation that appear at the specific region more easily be identified, solved the awkward problem of using capacitance touch screen palm or other maloperations to cause.The technical scheme of invention has improved recognition efficiency and the accuracy rate of capacitance plate to touch input operation, has improved user's input and has experienced.
It is above that invention has been described with reference to embodiment.Should be clear and definite be, the present invention has more than and is limited to specific embodiments described herein, but can do various do not depart from the art category, correction apparent to those skilled in the art, reformation and substitute.Therefore, the following claim of regulation has contained all this correction and changes that meet marrow of the present invention and category.
