Preset third predetermined value V3 and judge whether the 5th amplitude A 5 is greater than preset 4th predetermined value V4, i.e. step S308.Its
In, third predetermined value V3 refers to that moving sensing device 104 is in default on first direction D1 when electronic device 100 generates touch event
Acceptable peak swing value, and the 4th predetermined value V4 refers to the moving sensing device 104 when electronic device 100 generates touch event
In presetting acceptable peak swing value on second direction D2.Therefore, electronic device 100 need to be pre- less than first in the first amplitude A 1
Definite value V1, the second amplitude A 2 are greater than second predetermined value V2, and third amplitude A 3 is less than third predetermined value V3, and the 5th amplitude A 5 is less than
Determine that the first touch objects wear the finger of gloves for user in the case where 4th predetermined value V4, and carries out step S110.So
One, it can avoid electronic device 100 and occur in the case that first direction D1, second direction D2 and third direction D3 all have movement
Erroneous judgement.
In other embodiments, as shown in figure 8, step S108 also can separately include judging third amplitude A 3 and the 5th amplitude A 5
Whether less than the second amplitude A 2, i.e. step S408.Therefore, electronic device 100 need to be less than first predetermined value V1 in the first amplitude A 1,
Second amplitude A 2 is greater than second predetermined value V2, and third amplitude A 3 is less than third predetermined value V3, and the 5th amplitude A 5 is predetermined less than the 4th
Value V4, and third amplitude A 3 and the 5th amplitude A 5 less than the second amplitude A 2 in the case where determine that the first touch objects wear for user
The finger of gloves, and carry out step S110.
As shown in Fig. 1, Fig. 3 and Fig. 9, according to the judging result of control module 110, (it is greater than if the first amplitude A 1 is not less than
Or be equal to) first predetermined value V1 or the second amplitude A 2 no more than (being less than or equal to) second predetermined value V2, then carry out step
S112.Furthermore, it is understood that when electronic device 100 judges that the first amplitude A 1 is greater than or equal to first predetermined value V1, electronics dress
Setting 100 can detect that the position of the first touch objects, therefore can determine that the first touch objects may be, for example, the exposed finger of user.Cause
This, in step S112, control module 110 is to maintain the signal gain of signal amplification unit 106.Then step S104 is carried out,
Electronic device 100 is still maintained at normal mode.Specifically, signal gain is still maintained the first signal gain, makes control module
110, which can be identified user, touches touching signals caused by touch control sensor 102 using exposed finger.
Please continue to refer to Fig. 1 and Fig. 3, the sensing method of touch control of the present embodiment in electronic device 100 enter gloves mode it
After can separately include the following steps:
Step S116: carrying out touch control detection using touch control sensor 102, to generate one second touching signals S2, wherein the
Two touching signals S2 have one the 4th amplitude A 4；
Step S118: judging whether the 4th amplitude A 4 reaches a saturation value V5, if the 4th amplitude A 4 is greater than saturation value V5,
Step S120 is carried out, step S122 is otherwise carried out；
Step S120: the signal gain of signal amplification unit 106 is reduced；And
Step S122: the signal gain of signal amplification unit 106 is maintained.
The case where following elder generation with the second touch objects 120 is user's exposed finger explains, but not limited to this situation.
It please refers to Figure 10 and Figure 11 arranges in pairs or groups Fig. 1 and Fig. 3.After step S114, step S116 is carried out, user uses the second touch objects
120 touch electronic devices 100 are primary, therefore electronic device 100 can generate the second touching signals S2 using touch control sensor 102.
Also, moving sensing device 104 can generate a first movement signal MS1 on third direction D3, in generating one on first direction D1
Second movable signal MS2, and in one the 4th movable signal MS4 of generation on second direction D2.
Then, step S118 is carried out, the second touching signals S2 can be sent to control module 110, to penetrate control module 110
Judge whether the 4th amplitude A 4 reaches preset saturation value V5.Wherein, saturation value V5 is the producible maximum of touch control sensor 102
Amplitude.
Judging result according to control module 110 carries out step S120 if the 4th amplitude A 4 reaches saturation value V5.This
Situation be indicate the second touching signals S2 that is sent out of touch control sensor 102 for supersaturated signal, therefore 110 nothing of control module
Method analyzes numerical digit code corresponding to this second touching signals S2, i.e., can not judge the position of the second touch objects 120.Citing comes
It says, when the second touch objects 120 are, for example, the exposed finger of user or other generate highly sensitive object to touch control sensor 102
When body, the 4th amplitude A 4 of the second touching signals S2 can reach saturation value V5, therefore electronic device 100 and can not judge second
The position of touch objects 120.
When electronic device 100 can not judge the position of the second touch objects 120, step S120 is carried out, through control
The signal gain of the reduction signal amplification unit 106 of module 110.Then, step S104 is carried out, makes electronic device 100 from glove form
Formula is adjusted into normal mode.For example, signal gain can be back to the first signal gain from second signal gain reduction.By
This, when the second 120 touch electronic device 100 again of touch objects, touch control sensor 102 can produce the 4th touching signals S4, and
It has the 7th amplitude A 7 less than saturation value V5, as shown in figure 12.Therefore, control module 110 can be identified the second touch objects
120 touch the 4th touching signals S4 caused by touch control sensor 102, and then judge that the second touch objects 120 can be user
Using exposed finger, and it can normally detect the position of the second touch objects 120.
In other embodiments, step S118 alternative separately includes judging whether the second amplitude A 2 is greater than second predetermined value
V2.Therefore, electronic device 100 need to reach saturation value V5 in the 4th amplitude A 4, and the second amplitude A 2 is greater than second predetermined value V2's
