Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail, it is clear that described embodiment is only some embodiments of the present invention rather than whole embodiments.Based on the embodiment in the present invention, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
A kind of touch identification method that the embodiment of the present invention one provides, the flow chart of a kind of touch identification method that Fig. 1 provides for the embodiment of the present invention one is described below in detail as a example by Fig. 1.The executive agent of this touch identification method is the equipment with touch screen.As it is shown in figure 1, this touch identification method comprises the following steps:
Step S110, obtains touch point data by the intermittent scanning touch screen set.
The touch point data obtained can be one or more groups, often the corresponding touch point of group touch point data.
The data such as these touch point data may include that the size of current that touch screen four limit electrode sends, size of current and the touch point ratio to the distance of electrode, touch point capacitance matrix.
These touch point data, if determining that the quantity of touch point is at least two according to touch point data, are carried out disturbing data filtering to process, to obtain effective touch point by step S120.
The touch point on current touch screen and touch point quantity is would know that by the touch point data obtained.When the touch point quantity determined is multiple, it is likely due to what the multiple touch points operation that user carries out caused, it is also likely to be and causes owing to touch screen surface exists interfering material (such as water stain, steam, fog etc.), so cannot determine that whether operation now is the normal operating of user.Therefore, however, it is determined that touch point be multiple, need to obtain touch point data carry out disturb data filtering process, to obtain effective touch point, i.e. the touch point of user's practical operation.
The process that concrete interference data filtering processes is as in figure 2 it is shown, it carries out, for what the embodiment of the present invention one provided, the flow chart that interference data filtering processes to touch point data.
Step S121, determines the current period touch point that touch point data changed compared with the last cycle.
The touch point data that each cycle obtains can be temporarily held in the memorizer of equipment, in order to when the next cycle, utilizes whether data validation touch point, the touch point data of storage change.If it occur that change, then the point that explanation touch point data change is probably the touch point of user operation.
Concrete, the touch point data of the touch point data of each touch point of current period with a upper cycle correspondence position are compared, it is judged that whether the touch point data of those touch points change, to determine the touch point that touch point data change.If there is not touch point in a upper cycle correspondence position, then it is believed that the data of this touch point change.The touch point data produced due to interfering material are different from the touch point data produced during user's normal touch, therefore can be got rid of by the touch point that interfering material is produced by this step.But, now can not determine whether the touch point that touch point data change is that user operation produces, and therefore also needs to further confirm that, i.e. performs step S122-step S124 completely.
Step S122, determines area and/or the shape of this touch point changed according to touch point data.
It should be understood that it can also be multiple that the quantity of this touch point changed can be one.
Step S123, compares area corresponding for this touch point changed and/or shape with touch point set in advance area of reference and/or reference figuration, and difference is compared in acquisition.
Presetting touch point area of reference and/or reference figuration in equipment, this touch point area of reference and/or reference figuration can be multiple, such as finger touch point area of reference and/or reference figuration, nib touch point area of reference and/or reference figuration etc..
Step S124, is defined as effective touch point by comparing difference less than the touch point changed of threshold values set in advance.
Area and/or shape that the touch point that changes is corresponding are the least with the comparison difference of touch point set in advance area of reference and/or reference figuration, then illustrate that this touch point changed is closer to touch point area of reference and/or reference figuration.Therefore, a threshold values can be pre-set, as long as comparing difference to be regarded as effective touch point less than the touch point changed of threshold values.
If touch point set in advance area of reference and/or reference figuration are multiple, as long as one of them compares difference is less than threshold values, then effective touch point can be confirmed as in the touch point that this changes.Such as, the comparison difference of the touch point area changed and/or shape and finger touch point area of reference and/or reference figuration is more than threshold values, and with the comparison difference of nib touch point area of reference and/or reference figuration less than threshold values, then it is believed that this touch point is user utilizes the operation that writing pencil carries out, it is thus identified that be effective touch point.
Got rid of by the touch point carrying out described touch point data disturbing data filtering to process the interfering material generation in the multiple touch points that can will confirm that, thus obtain the touch point that user's practical operation produces.
Step S130, performs corresponding touch event according to effective touch point.
Equipment only carries out the touch event that effective touch point is corresponding, is not carried out the touch point correspondence touch event caused by interfering material, can be prevented effectively from the problem identifying mistake.
It addition, after step silo, the method is further comprising the steps of: if determining that the quantity of touch point is one, determines that this touch point is effective touch point according to touch point data.
If touch point data are one, it is believed that this touch screen surface does not exist interfering material, then can determine that this touch point is effective touch point, i.e. this touch point is the normal operating of user.Therefore, the touch event that this effective touch point is corresponding is directly performed.
Utilize the touch identification method that the embodiment of the present invention one provides, when being multiple in the touch point determined by touch point data, carry out touch point data disturbing data filtering, the touch point accurately of user's practical operation can be got, then perform the touch event that correct touch point is corresponding, thus be prevented effectively from when water smoke, steam, the interfering material such as water stain occurs in touch screen occur touching insensitive, drift about, identify the problems such as mistake.

Concrete, first determines that the touch point data of the touch point data of the touch point of current period with a upper cycle correspondence position are compared by module 321, judge whether the touch point data of this touch point change, to determine the touch point that touch point data change.It should be understood that it can also be multiple that the quantity of this touch point changed can be one.If a upper cycle correspondence position does not exist touch point, then first determines that module 321 can confirm that the data of this touch point change.The touch point data produced due to interfering material are different from the touch point data produced during user's normal touch, therefore determine that the touch point that interfering material produces can be got rid of by module 321 by first.But, now can not determine whether the touch point that touch point data change is that user operation produces, and therefore also needs to other module and further confirms that completely.
Second determines that module 322 for determining area and/or the shape of this touch point changed according to touch point data.
Comparison module 323 is for comparing area corresponding for this touch point changed and/or shape with touch point set in advance area of reference and/or reference figuration, and difference is compared in acquisition.
Presetting touch point area of reference and/or reference figuration in device, this touch point area of reference and/or reference figuration can be multiple, such as finger touch point area of reference and/or reference figuration, nib touch point area of reference and/or reference figuration etc..
3rd confirms that module 324 is for being defined as effective touch point by comparing difference less than the touch point changed of threshold values set in advance.
Area and/or shape that the touch point that changes is corresponding are the least with the comparison difference of touch point set in advance area of reference and/or reference figuration, then illustrate that this touch point changed is closer to touch point area of reference and/or reference figuration.Therefore, a threshold values can be pre-set, as long as comparing difference to be regarded as effective touch point less than the touch point changed of threshold values.
If touch point set in advance area of reference and/or reference figuration are multiple, as long as one of them compares difference is less than threshold values, then the 3rd confirms that effective touch point just can be confirmed as in the touch point that this changes by module 324.
Carry out disturbing data filtering to process the touch point eliminating that the interfering material in the multiple touch points that can will confirm that produces to described touch point data by filter unit 320, thus obtain the touch point that user's practical operation produces.
