Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Please refer to fig. 1 and fig. 2, wherein fig. 1 is a flowchart illustrating a method for preventing a touch screen from being triggered by mistake according to an embodiment of the present invention, and fig. 2 is a flowchart illustrating a specific flowchart of step S2 in fig. 1. The method for preventing the touch screen from being triggered mistakenly provided by the embodiment of the invention comprises the following steps:
s1, detecting whether the earphone interface is in the insertion state;
s2, when detecting that the earphone interface is in the insertion state, judging whether the terminal is in the user operation state;
s3, when the terminal is in the non-user operation state, forbidding the touch response processing to the touch data detected by the touch screen control unit;
s4, when the terminal is in the user operation state, judging whether the data characteristics of the touch data detected by the touch screen control unit are matched with the earphone cord touch data characteristics;
s5, when the data characteristic of the touch data is matched with the earphone cord touch data characteristic, prohibiting touch response processing on the touch data detected by the touch screen control unit;
and S6, when the data characteristic of the touch data is not matched with the earphone cord touch data characteristic, performing touch response processing on the touch data detected by the touch screen control unit.
It should be noted that, when the earphone cord touches the touch screen, the data characteristic of the touch data detected by the touch screen control unit is a curve or is similar to a straight line, and when the touch screen is touched by a finger, the data characteristic of the touch data detected by the touch screen control unit is an ellipsoid, so that it can be determined whether the touch data is triggered by the earphone cord according to the data characteristic of the touch data detected by the touch screen control unit. The data characteristics of the touch data are well known to those skilled in the art and are therefore not described in detail in this application.
In this embodiment, when it is detected that the earphone interface is in the insertion state, the operation state of the terminal is determined first, the touch response processing on the touch data detected by the touch screen control unit in the non-user operation state is prohibited, then the characteristics of the touch data in the user operation state are determined, and the touch response processing on the touch data matched with the characteristics of the earphone line touch data detected by the touch screen control unit is prohibited. By the method, the earphone wire is prevented from triggering the touch screen by mistake so that the terminal can make relevant touch response processing, only touch data which are detected in the user operation state and have unmatched characteristics with the earphone wire touch data are subjected to touch response processing, and the touch screen is effectively prevented from being triggered by the earphone wire by mistake.
In an alternative embodiment, the step S2 includes:
s21, when the earphone interface is detected to be in the inserting state, judging whether the terminal is in the shielding state through the receiving sensor and judging whether the terminal is in the weak light environment through the ambient light sensor;
and S22, when the terminal is in the shielding state and in the low-light environment, judging that the terminal is in the non-user operation state.
When the receiving sensor detects that a shielding object exists in the detection range and the ambient light sensor detects that the current ambient light is weak, namely the current environment of the terminal does not reach the condition suitable for the user to operate the terminal, the user does not operate the terminal, and therefore the terminal is judged to be in a non-user operation state. Therefore, touch data detected by the touch screen control unit cannot be subjected to touch response processing, and the touch screen is prevented from being triggered by the earphone cable by mistake.
In an alternative embodiment, the step S2 further includes:
s23, when the terminal is in a non-shielding state or in a non-weak light environment, judging whether the terminal is in a motion state through the acceleration sensor;
s24, when the terminal is in the non-motion state, judging that the terminal is in the non-user operation state;
and S25, when the terminal is in the motion state, judging that the terminal is in the user operation state.
When the receiving sensor does not detect a blocking object in the detection range or the ambient light sensor detects that the current ambient light is strong, whether the current user is operating the terminal cannot be directly judged, so that the motion state of the current terminal needs to be judged through the acceleration sensor. The acceleration sensor detects whether the coordinate information in the three directions changes within a certain time threshold value by acquiring the coordinate information in the x direction, the y direction and the z direction, and when the coordinate information in the three directions does not change within the certain time threshold value, the position of the terminal is not changed, namely, the terminal is not operated by a current user, so that the terminal is judged to be in a non-user operation state; when the coordinate information in the three directions changes within a certain time threshold, the terminal position changes, namely the current user operates the terminal, so that the terminal is judged to be in the user operation state. Therefore, when the current environment meets the condition that the user is suitable for operating the terminal, if the terminal is in a non-motion state, touch data detected by the touch screen control unit cannot be subjected to touch response processing; if the terminal is in a motion state, data matching needs to be carried out on the data characteristics of the touch data detected by the touch screen control unit, touch response processing needs to be carried out on the touch data which is not matched with the earphone cord touch data characteristics, touch response processing needs to be forbidden to be carried out on the touch data matched with the earphone cord touch data characteristics, and therefore the touch screen is effectively prevented from being triggered by the earphone cord in a false mode.
The following will illustrate embodiments of the invention in different use scenarios:
scenario one: the user places the terminal in a bag or a pocket and plays audio through the earphone at the same time. At this time, the receiving sensor determines that the receiving sensor is currently in a shielding state and the ambient light sensor determines that the receiving sensor is currently in a low-light environment, that is, the current state of the terminal is determined to be a non-user operation state, and at this time, the touch response processing on the touch data detected by the touch screen control unit is prohibited. Therefore, in the first scenario, the touch data detected by the touch screen control unit will not be processed by touch response, which not only prevents the touch screen from being triggered by the earphone cord, but also prevents the touch screen from being triggered by other objects in the bag or the pocket.
Scenario two: the user places the terminal fixedly and does not operate the terminal, and there is not the shelter in proximity sensor's response region simultaneously to play the audio frequency through the earphone. At this time, the proximity sensor judges that the terminal is currently in a non-shielding state, and judges the current motion state through the acceleration sensor, at this time, because the user fixedly places the terminal and does not operate the terminal, the acceleration sensor judges that the terminal is currently in the non-motion state, the current state of the terminal is judged to be in the non-user operation state, and touch response processing on touch data detected by the touch screen control unit is forbidden. Therefore, in the second scenario, the touch data detected by the touch screen control unit will not be processed by touch response, so that the touch screen is prevented from being triggered by the earphone cord by mistake.
Scenario three: the user is operating the terminal while inserting headphones to play audio. At this time, the receiving sensor judges that the receiving sensor is currently in a non-shielding state or the ambient light sensor judges that the receiving sensor is currently in a non-weak light environment, the current motion state is judged through the acceleration sensor, the acceleration sensor judges that the receiving sensor is currently in a motion state because a user operates the terminal, the current state of the terminal is judged to be the user operation state, if the touch data is judged to be detected by the touch screen control unit at this time, whether the data characteristics of the touch data detected by the touch screen control unit are matched with the earphone wire touch data characteristics is judged, touch response processing is carried out on the touch data which is not matched with the earphone wire touch data characteristics, and touch response processing is forbidden to the touch data which is matched with the earphone wire touch data characteristics. Therefore, in scenario three, that is, in the user operation state, it is further necessary to determine the data characteristics of the touch data detected by the touch screen control unit, perform touch response processing on the touch data that does not match the touch data characteristics of the earphone cord, and not perform touch response processing on the touch data that matches the touch data characteristics of the earphone cord, thereby avoiding the false triggering of the touch screen by the earphone cord.
The above three usage scenarios are three usage scenarios listed for better illustrating the implementation of the embodiment of the present invention, and are not all usage scenarios of the embodiment of the present invention.
In an alternative embodiment, the method further comprises:
when the terminal is in a non-user operation state, judging whether a display screen is in a bright screen state;
when the display screen is in a bright screen state, controlling the touch screen control unit to work in a mode capable of detecting touch data;
when the display screen is in a screen-off state, controlling the touch screen control unit to work in a low-power-consumption working mode; and in the low power consumption mode, the touch screen control unit is forbidden to detect the touch data.
When the display screen is in a bright screen state, the terminal displays current state information through the display screen, the touch screen control unit works in a mode capable of detecting touch data, and at the moment, if the touch data is detected, the terminal enters a user operation state; otherwise, the terminal maintains the non-user operation state. It should be noted that the mode capable of detecting touch data is used to change the user operation state of the terminal, specifically, when touch data is detected in the mode capable of detecting touch data, the terminal enters the user operation state; if the touch data is not detected in the mode in which the touch data can be detected, the terminal maintains a non-user operation state.
When the display screen is in the screen rest state, the terminal does not display the current state information, which also indicates that the user does not need to input touch data at this time, so that the touch screen control unit is controlled to work in the low power consumption working mode, and the touch screen control unit is prohibited from detecting the touch data, namely the touch screen control unit does not have the function of detecting the touch data, so that the power consumption of the terminal can be reduced, and the endurance time of the terminal can be prolonged.
In an optional implementation mode, the switching between the screen-on state and the screen-off state of the display screen is realized by pressing a power key of the terminal.
In an alternative embodiment, the method further comprises:
when the terminal is in a user operation state, acquiring the capacitance value change condition of the touch data within a preset time threshold value through a touch screen control unit, and calculating the capacitance average change value of the touch data;
and updating the firmware threshold of the touch screen control unit according to the capacitance average change value so as to update the sensitivity of the touch screen.
Acquiring a capacitance value change condition and calculating an average capacitance change value in a user operation state, updating a firmware threshold value of a touch screen control unit by using the average capacitance change value, detecting a capacitance change value caused by touch when the touch occurs, and forbidding touch response processing on touch data if the capacitance change value caused by the touch is smaller than the firmware threshold value; and if the capacitance change value caused by the touch is larger than or equal to the firmware threshold, performing touch response processing on the touch data. Through the method, the personalized touch screen sensitivity can be set for different users, and the probability of false triggering can be reduced.
Compared with the prior art, the embodiment of the invention has the beneficial effects that: the embodiment of the invention provides a method for preventing a touch screen from being triggered mistakenly, which comprises the following steps: detecting whether the earphone interface is in an insertion state; when detecting that the earphone interface is in an insertion state, judging whether the terminal is in a user operation state; when the terminal is in a non-user operation state, prohibiting touch response processing on touch data detected by the touch screen control unit; when the terminal is in a user operation state, judging whether the data characteristics of the touch data detected by the touch screen control unit are matched with the earphone cord touch data characteristics; when the data characteristics of the touch data are matched with the touch data characteristics of the earphone cable, the touch response processing of the touch data detected by the touch screen control unit is forbidden; and when the data characteristics of the touch data are not matched with the earphone cord touch data characteristics, performing touch response processing on the touch data detected by the touch screen control unit. When the terminal detects that the earphone interface is in the insertion state, whether touch response processing needs to be carried out on the touch data is judged according to the current operation state of a user and the data characteristics of the touch data, and when the terminal is in the non-user operation state or the touch data is matched with the earphone line touch data, the touch response processing on the touch data is forbidden, so that the touch data which is not operated by the user is not subjected to the touch response processing, and the touch screen is effectively prevented from being triggered by the earphone line in error.
