Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
This application provides the method for adjustment of a kind of sensitivity of touch screen and system, by detecting capacitance present amount and the current context information of the touch area of touch screen, and according to preset rules, obtain the first output signal of the described touch screen corresponding with described capacitance present amount, and the second output signal of the described touch screen corresponding to described current context information prestored, and after obtaining the target sensitivity parameter matched with this first output signal and the second output signal, utilize the current sensitivity degree of touch screen described in this target sensitivity parameter adjustment, visible, the target sensitivity parameter that the application determines take into account touch screen and is currently located practical situation and the operator's actual touch situation to this touch screen touch area of environment, so that the touch screen after adjusting can adapt to the touching intensity of current environment and this operator, not only avoid the maloperation caused because this touch area pressure is too small for operator, it also avoid the inconvenience that practical operation is brought by the false triggering caused because of outside environmental elements simultaneously.
Understandable in order to enable the above-mentioned purpose of the present invention, feature and advantage to become apparent from, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As it is shown in figure 1, the schematic flow sheet of method of adjustment embodiment of a kind of sensitivity of touch screen provided for the application, the method may comprise steps of:
Step S110: the capacitance present amount of the touch area of detection touch screen and current context information.
Wherein, this current context information can include Current Temperatures information and/or current humidity information, but is not limited thereto.
In the present embodiment, it have been investigated that, temperature when environment, when humidity reaches certain value, the terminal being positioned under environment easily causes false triggering, that is, temperature when environment, when humidity reaches certain value, even if the touch screen of this terminal is not carried out touch-control by operator, also the output signal of these touchscreen senses parts can be made (in order to facilitate subsequent descriptions because of external environment, in this case output signal is designated as and a) exceedes default report point threshold values, this terminal is thought and now there occurs touch event, and report the position coordinates of the touch point producing this output signal.
And, when operator's finger contacts the touch area of touch screen, but make the output signal of these touchscreen senses parts (in order to facilitate subsequent descriptions because of finger state (such as finger pressure), in this case output signal is designated as b) less than this report point threshold values preset, even if this touch screen of operator's touch screen in this case, this touch of also None-identified of this touch screen, or therefore can obtain the position coordinates of touch point of mistake, practical operation can be brought a lot of inconvenience equally.
As can be seen here, not only the touch condition of the touch area of touch screen can be caused false triggering by the finger of operator, and, touch screen local environment also can because of the false triggering of its touch screen, so, in order to avoid the false triggering to touch screen, the application will suitably adjust above-mentioned default report point threshold values, namely the sensitivity of this touch screen is adjusted, so that the report point threshold values after adjusting is more than a and less than b.

In like manner, utilize the comparison table of environmental information and the sensitivity of touch screen prestored, search the second output signal of the described touch screen corresponding with described current context information.
As the above analysis, this first output signal be operator to touch screen touch-control time produce, and this second output signal be this touch screen without touch-control time produce.
Step S130: obtain the target sensitivity parameter matched with this first output signal and the second output signal.
Optionally, in the present embodiment, for obtaining the mode of target sensitivity parameter, can according to the sensitivity level division rule of default described touch screen, determine that exporting signal and described second with described first exports the target sensitivity grade that signal is corresponding, obtain the target sensitivity parameter corresponding with this target sensitivity grade afterwards again, but be not limited to this kind of acquisition mode, can also being obtained by modes such as calculating, the application no longer describes in detail one by one at this.
Wherein, it should be noted that, the sensitivity level division rule of this touch screen is not especially limited by this enforcement, it can be determined in conjunction with above-mentioned experiment, as shown in Figure 2, if under varying environment information, touch terminal touch screen does not make its signal intensity curve exported be 210, when this touch screen is contacted by different operating person, the signal intensity curve of this touch screen output is 230, situation of change by curve in Fig. 2 210 and curve 230, can by its C1, C2, these grades of C3 and C4, the sensitivity of touch screen can be determined according to the situation of change of its curve 210 and curve 230 in each grade, the i.e. report point threshold values of touch screen, curve 220 in Fig. 2, but it is not limited to Fig. 2 and presets this report point threshold values, can suitably adjust this report point threshold values, as long as ensureing that curve 220 is between curve 210 and curve 230.
Step S140: utilize the current sensitivity degree of touch screen described in described target sensitivity parameter adjustment.
In the present embodiment; do not limit and how to utilize the acquisition target sensitivity parameter setting to touch screen; to reach to adjust the detailed process of this sensitivity of touch screen; pay what creative work was determined so long as not those skilled in the art; belonging to the application protection domain, this enforcement is not described in detail in this.
Optionally, on the basis of above-described embodiment, the first variable quantity of described first output signal and the second variable quantity of described second output signal can also be monitored, if described first variable quantity and/or described second variable quantity reach pre-set threshold value, to again detect capacitance present amount and the current context information of the touch area of touch screen, and then readjust the sensitivity of touch screen in the manner described above; If described first variable quantity and described second variable quantity all not up to pre-set threshold value, are now not required to adjust the sensitivity of this touch screen.
Wherein, above-mentioned pre-set threshold value can according to experiment or technical staff empirically determined, and it is not especially limited by the application.
As another embodiment of the application, on the basis of above-described embodiment, when described first variable quantity and/or described second variable quantity reach pre-set threshold value, the method can also export the information that the sensitivity of presently described touch screen is not good, to provide operator's present terminal sensitivity of touch screen improper, it is possible to etc. terminal adjust this sensitivity of touch screen after operate on it again.
