In order to facilitate understanding of the embodiments of the present invention, a communication network system on which the mobile terminal of the present invention is based is described below.
Based on the above mobile terminal hardware structure, various embodiments of the manipulation method of the present invention are proposed.
The first embodiment:
aiming at the phenomenon that the probability of misoperation is greatly improved when a user uses the mobile phone by the aid of a simplified trend of appearance design of the mobile phone and an inductive button design mode, the embodiment of the invention provides a mode of identifying touch operation through multi-level judgment, and misoperation is avoided.
As shown in fig. 2, a flowchart of the false touch prevention control method provided in this embodiment is specifically included in the following steps:
s201, detecting the current working state of the mobile terminal.
In the embodiment, the working state includes a screen-on state and a screen-off state, and the screen-off state is the most easily unconscious touch, for example, when a user places a mobile phone in a pocket or a backpack, due to the existing arrangement of touch keys, the trigger control is much more sensitive than the trigger of pressing the key by a physical entity, in the backpack, the mobile phone often collides with other objects, and the strength of the collisions is enough to realize the trigger of the key; for the bright screen state, misoperation is rarely caused, because in the bright screen state, a user intentionally avoids a key-off area.
And S202, if the mobile terminal is in the screen extinguishing state, starting a false touch prevention control mode of the mobile terminal.
In this step, the probability of the misoperation of the terminal in the screen-off state is mainly aimed at, and of course, the method is also applicable to key trigger control in the screen-on state, and only the method of setting the switch improves the selective use of the user.
In this embodiment, the anti-false-touch control mode essentially starts a control circuit, and the control circuit is used together with the touch key, that is, in the screen-off state, if a user needs to effectively operate the touch key on the mobile terminal, the user needs to operate the control circuit and the touch key at the same time.
In practical applications, the control circuit may be a trigger switch, a complete detection circuit, or even a device or structure such as a physical key.
S203, detecting whether the touch key is triggered.
In this embodiment, the triggering of the touch key is a fixed triggering threshold, and when the force of the touch key reaches the triggering threshold, the touch key is triggered.
In this embodiment, in the screen-off state, the critical point of the trigger is set to be higher than the critical point in the screen-on state, so that the elimination of some misoperation can be avoided, and the setting of the critical point is increased to perform certain screening on the false touch in the screen-off state.
In practical applications, for the pressure key, whether the pressure key is triggered or not can be determined by detecting the deformation degree of the pressed key or by detecting the pressing strength.
And S204, if the trigger signal is triggered, acquiring a control signal output by the key control circuit.
In this embodiment, the control signal may be a signal generated by the key control circuit detecting the trigger switch, a signal generated by the circuit itself, or a potential signal of an output or input pin on a certain device in the circuit.
And S205, judging whether the control signal meets a trigger condition.
The triggering condition refers to whether the control signal is at a low level or a high level, but in practical applications, if the key control circuit is also implemented by using a key, the triggering condition may also be a triggering condition of the key itself, such as pressure, deformation, etc., and even a generated impedance.
And S206, determining whether the triggering of the touch key is effective according to the judgment result.
In this step, if the control signal meets the trigger condition, it is considered that the touch key itself is also triggered in the current state, and meanwhile, the control signal of the control circuit also meets, it is considered that the touch operation of the touch key is valid, and corresponding operation is performed on the terminal according to the instruction corresponding to touch;
if the control signal does not satisfy the trigger condition, it is determined that the touch operation of the touch key is invalid in the current state, even though the touch key itself is triggered, but the control signal of the control circuit does not satisfy the condition, or the touch key itself is not triggered, and at the same time, the control signal of the control circuit does not satisfy the condition, it is determined that the touch operation of the touch key is invalid.
In this embodiment, the touch key may be one of a pressure key, a capacitance key and a proximity key.
If the touch key is a pressure key, the detecting whether the touch key is triggered comprises:
collecting the force and the deformation degree generated by pressing the pressure type key by the user;
comparing the magnitude relation between the strength and/or the deformation degree and a preset trigger threshold value;
determining whether the compression is effective according to a result of the comparison.
In this embodiment, the key touch circuit may be implemented by using a button, or may be implemented by using a simple trigger circuit, and if the key control circuit is a metal key, the acquiring the control signal output by the key control circuit includes:
detecting the condition that the metal key is pressed;
and judging whether the metal key is in short circuit connection or not based on the pressing condition, and outputting a low-level signal if the metal key is in short circuit connection.
In practical application, the metal keys are arranged on the shell of the mobile terminal and correspond to the touch keys, one touch key corresponds to one metal key, and effective triggering can be calculated only by pressing two keys simultaneously in a screen-off state. Specifically, the metal keys are exposed on the shell of the terminal through the two metal sheets, when a user needs to control the volume in a screen-off state, the corresponding volume keys are found firstly, then the keys are pressed, fingers simultaneously contact the two metal sheets, the metal keys are connected, namely, the skin impedance of the user is connected into the key circuit, after the skin impedance of the human body is connected into the key circuit, the control signal in the key circuit can be changed, the control signal is set to be 0, namely, the low level, and in this time, the keys pressed by the user adopt effective input, so that the volume is adjusted.
In this embodiment, if the key control circuit is in a circuit structure, the key control circuit is specifically composed of a transistor Q1, two resistors (R1, R3) and a key R2, as shown in fig. 6, wherein one end of each of the two resistors is connected to a power supply VDD, and the other end is connected to a collector and a base of the transistor Q1; one end of the key R2 is connected with the base electrode of the triode Q1, and the other end of the key R2 is connected with the emitting electrode of the triode Q1 and grounded.
At this time, the control signal output by the collection key control circuit includes:
detecting whether the key is pressed to be switched on or not;
and if so, the triode is conducted, the potential of the collector of the triode is detected, and the potential is output as a control signal.
If the trigger condition is that the low level is valid, determining whether the triggering of the touch key is valid according to the judgment result comprises:
if the control signal is at a low level, determining that the triggering of the touch key is legal touch operation;
and if the control signal is in a non-low level, determining that the triggering of the touch key is illegal touch operation.
In summary, according to the method for controlling the false touch prevention provided by this embodiment, the false touch prevention control mode is started when the mobile terminal is in the screen-off state, and in this mode, signals of the touch key and the key control circuit are detected respectively, and only when both signals meet the condition, it is determined that the touch is valid, and if not, the touch is invalid, so that the design cost of the circuit can be reduced, the reliability and stability of the product are improved, the use experience of the user is improved, the probability of the false touch is reduced, and the after-sale maintenance cost is reduced by the setting mode of separating the devices.
Second embodiment:
referring to fig. 3, a detailed flowchart of the false touch prevention control method provided in this embodiment is shown, where this embodiment is described by taking a volume adjustment key as a pressure key at a side of a terminal as an example, and the specific method includes the following steps:
s301, arranging a metal key on the side of each volume adjusting key.
In this embodiment, an equivalent circuit structure corresponding to the metal key is shown in fig. 6 and 7, and the equivalent circuit specifically includes a triode Q1, two resistors (R1, R3) and a key R2, as shown in fig. 6, wherein one end of each of the two resistors is connected to a power supply VDD, and the other end is connected to a collector and a base of the triode Q1; one end of the key R2 is connected with the base electrode of the triode Q1, and the other end of the key R2 is connected with the emitting electrode of the triode Q1 and grounded.
Based on the circuit shown in fig. 6, if the user's finger touches the metal key, Q1 is turned on because the human body impedance mainly consists of skin impedance and internal impedance, and in the whole impedance network, the skin impedance mainly plays a role of skin impedance, and the skin impedance mainly refers to epidermis impedance, the impedance of the outermost stratum corneum of the epidermis is very large, and the resistivity of the whole impedance network is 100-1000K Ω × m in a dry and clean state. Under the condition that the key1 and the metal sheet are pressed down simultaneously, the skin impedance is realized at R2, voltage division is realized, the Q1 tube is closed, and the low level is realized, so that the CPU recognizes the low level through the GPIO, namely, the metal key is judged to be pressed down.
S302, whether the volume adjusting key is triggered or not is detected.
In this embodiment, whether the button is triggered or not can be determined by detecting the deformation degree of the pressed button, or by detecting the pressing strength. When it is detected that the volume adjustment key is triggered, step S303 is executed, otherwise, the process is ended.
S303, whether the metal key is pressed to be connected or not is detected.
If the user is detected to press, the user is indicated to switch on the two metal sheets on the metal key through fingers, at this time, the skin impedance of the human body is connected into the circuit, the base voltage in the Q1 can be boosted due to the resistivity of the skin of the human body being 100-1000K omega m, so that the conduction of the Q1 is realized, after the conduction, the voltage of the collector can be lowered to be low level, and at this time, the mobile terminal detects that the potential is changed, and the pressing of the volume adjustment key at this time is indicated to be effective.
And S304, detecting the potential of the collector of the triode Q1.
S305, if the potential of the collector is low.
And S306, executing the control operation corresponding to the pressed key.
In this embodiment, the methods of steps S301 to S306 are all implemented based on the terminal being in the screen-off state, and when the terminal is in the screen-on state, misoperation is rarely occurred, because in the screen-on state, the user intentionally avoids the key-off region. If the control is needed to be realized in the bright screen state, whether the mode control key is selected or not can be controlled by arranging a switch.
In summary, in the embodiment, when the mobile terminal is in the screen-off state, the anti-false-touch control mode is started, and in this mode, signals of the touch key and the key control circuit are respectively detected, and only when both signals meet the condition, it is determined that the touch is valid, and if not, the touch is invalid, so that a device separation mode can be realized, the manufacturing cost is reduced, and the mobile terminal is suitable for popularization.
