Step S101 detects the capacitance variations on the touch-screen of described contactor control device, and obtains the capacitance change at capacitance variations place.
In some embodiments of the invention, for example detect the capacitance variations on the touch-screen of contactor control device by capacitance detection unit and obtain the capacitance change at capacitance variations place.Because capacitance detection unit can detect the capacitance variations situation of touch-screen constantly, therefore can momentarily obtain the capacitance change at touch-screen capacitance variations place.
Step S102 judges according to described capacitance change whether the touching object closes on described touch-screen, and triggers respectively not closing signal of object closing signal and object.
In other words, because the change of the distance of touching object and touch screen surface, the position electric capacity of the point on this touching object and the touch-screen that touch-screen will contact will change and produce a capacitance change, like this, capacitance change and predetermined capacitance threshold value of this point can be compared, thereby can roughly determine a scope interval of distance between this touching object and the touch screen surface, and then, can determine whether this touching object closes on touch-screen, and trigger respectively the adjacent signal of object and the not closing signal of object according to definite result.
Step S103, if receiving described object, the controller of described contactor control device do not continue to receive not closing signal of described object within closing signal and the predetermined time cycle, the controller of then controlling described contactor control device enters dormant state, and returns execution in step S101.
Particularly, if the controller of described contactor control device is closing signal at the upper signal that once receives, and be that described object is not during closing signal at the signal that this time receives, the beginning timing, and continuing to receive not closing signal of described object within the predetermined time cycle, the controller of then controlling described contactor control device enters dormant state.

At first described capacitance change and the first predetermined capacitance threshold value are compared.In concrete the application, the first predetermined capacitance threshold value can be measured in advance according to corresponding self-capacitance touch screen or mutual capacitance screen.
Then when judging described capacitance change greater than described the first predetermined capacitance threshold value, trigger described object closing signal, otherwise trigger not closing signal of described object.
Particularly, send to change if capacitance detection unit detects the electric capacity of a certain position on the touch-screen, and variable quantity is greater than the first predetermined capacitance threshold value, then thinking has object to close on touch-screen, then triggers described object closing signal.If judging does not have object to close on touch-screen, then trigger not closing signal of object.For example, the first predetermined capacitance threshold value that it adopts when object closes on touch-screen is Δ C1, and capacitance change is Δ C, and when judging Δ C1≤Δ C, i.e. expression has object to close on touch-screen, triggers the physics closing signal this moment.According to above-described embodiment, in step S104, after after controller receives the physics closing signal, entering duty, also be used for judging according to capacitance change whether described touching object is effectively touched described touch-screen and triggered the signal that is associated with described effective touching.
As shown in Figure 2, judge that whether described touching object is effectively touched described touch-screen and triggered the signal that is associated with described effective touching, is specially following steps:
Step S1041: described capacitance change and the second predetermined capacitance threshold value are compared.
Step S1042: if described capacitance change greater than described the second predetermined capacitance threshold value, then triggers effective touch signal and offers the controller of described contactor control device, otherwise return execution in step S101.For example, the Second Threshold that adopts when object effectively touches touch-screen is Δ C2.Significantly, Δ C2 should be greater than Δ C1.And the capacitance change of this moment is designated as Δ C, when judging Δ C2≤Δ C, represents that namely object effectively touches touch-screen, triggers effective touch signal and offers controller.For example, controller obtains the coordinate of effective touch point according to effective touch signal, thereby judges the icon that effectively touches, and the instruction that is associated of execution icon.As open an application program, input characters etc.
