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 some, not all, embodiments of the present invention. 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.
The inventor finds that in the process of implementing the present invention, the working principle of the capacitive touch technology is that when the distance between the external conductor and the sensing electrode changes, the change of the ground capacitance of the sensing electrode is caused, so that the touch operation of touching the sensing electrode area by a finger (i.e. the external conductor) is detected. Even if the touch action is unintentional, the scheme still judges that the touch operation is an effective touch input, so that the operation corresponding to the touch input is triggered. Therefore, the inventors found that the touch function using the sensing electrodes is prone to cause a problem of erroneous touch, which results in a high erroneous touch rate of the touch function.
In order to solve the above technical problem and better implement the touch function of the wearable device, the embodiment of the present invention is directed to determining whether a touch action received by the sensing electrode is intentional or unintentional, so as to refuse to respond to the touch action when determining that the touch action is unintentional, thereby reducing the false touch rate of the touch function.
Specifically, referring to fig. 1, a flowchart of a touch control method according to an embodiment of the present invention is shown, and is applied to a wearable device including a first sensing electrode and a first pin for serial port communication, and at least one second sensing electrode.
The wearable device may be a smart watch, or smart glasses (e.g., AR (Augmented Reality) glasses), or a headset device.
Hereinafter, the wearable device is taken as an example for explanation, and when the wearable device is a smart watch or smart glasses, the method is similar, and reference is made to the following example, so that the description is omitted.
In one example, fig. 2 shows a side schematic view of a headset profile; fig. 3 shows a schematic view of the base 11 of the ear stem of fig. 2.
Fig. 2 shows 5 sensing electrodes (i.e., cap sensors). The cap sensor4# and the cap sensor 5# are used for realizing the function of detecting whether the earphone is in a wearing state; the at least one second sensing electrode of the ear handle side wall comprises a cap sensor1#, a cap sensor 2# and a cap sensor 3#, and the three second sensing electrodes can be used for realizing touch operation functions of clicking, double clicking, long pressing, sliding up and down and the like so as to control audio.
As shown in fig. 3, the headset base has 3 sensing electrodes (here, metal contact electrodes), which are a metal contact electrode 21 of VBUS (USB voltage (5V)), and a metal contact electrode 22 of GND (power ground, 0 level), respectively, wherein the metal contact electrode 21 and the metal contact electrode 22 are used for headset charging; in addition, the base further includes a metal contact electrode 23 for serial port communication (i.e., the first sensing electrode for serial port communication described above), where the metal contact electrode 23 is a metal contact electrode of UART (Universal Asynchronous Receiver/Transmitter)) _ TX (transmit)/RX (receive). The metal contact electrode 23 may be used to transfer data to upgrade the headset system or to analyze problems, etc., when used for UART communication.
In the embodiment of the invention, the metal contact electrode 23 of the UART _ TX/RX can be multiplexed as capsensor 6# of the earphone.
With continued reference to fig. 4, the circuit connection relationship between the respective modules of the headset of the above-described embodiment of the present invention is shown.
The headset may include a headset Host end (i.e., Host of fig. 4), a touch detector (i.e., TP sensor module of fig. 4), and an Analog Switch module for serial communication (i.e., Analog Switch module of fig. 4).
As shown in fig. 4, 5 pins of the TP sensor module are connected to the cap sensor1#, the cap sensor 2#, the cap sensor 3#, the cap sensor4#, and the cap sensor 5# in fig. 2.
In fig. 4, two pins on the left side of the Analog Switch module are a UART _ TX pin and a UART _ RX pin, respectively, and the two pins are electrically connected to the host; the Analog Switch module has a pin 24 on the right side that is electrically connected to the metal contact electrode 23 in fig. 3. In addition, the Analog Switch module has a Switch pin and an Enable pin inside, which are not shown.
In addition, as shown in fig. 4, a pin 25 is led out from the TP sensor module to electrically connect with the metal contact electrode 23 in fig. 3.
The host can Enable the Switch pin and the Enable pin of the Analog Switch module to be placed in different states by controlling the electrical frequency of the input Analog Switch module. Therefore, the internal Switch of the Analog Switch module for serial port communication is in a closed or open state, and the metal contact electrode 23 can communicate with the pin 25 of the TP sensor module, or the metal contact electrode 23 communicates with the UART _ TX pin and the UART _ RX pin of the Analog Switch module.
Based on the above fig. 2 to fig. 4, the flow according to the embodiment of the present invention is explained in detail, and the flow includes the following steps:
in an example, as shown in fig. 2 and 4, the TP sensor module may determine that the earphone is in a wearing state if the capacitance variation of the cap sensor4# and the capacitance variation of the cap sensor 5# are both greater than a first preset threshold (for a specific detection method, the following embodiment of determining whether the first sensing electrode receives the first touch input may be referred to, and details are not repeated here), and if so, determine that the earphone is in the wearing state; the TP sensor module can report information indicating that the earphone is in a wearing state to the Host; the Host can then change the electrical frequency sent to the Analog Switch module, so that the Switch pin of the Analog Switch module is set high (e.g. 1) and the Enable pin is set high (e.g. 1), that is, the two pins are set to be in (1,1), so that the internal Switch of the Analog Switch module is turned off, thereby disconnecting the two pins (i.e. the first pin in this step), i.e. the UART _ TX pin and the UART _ RX pin on the left side of fig. 4, from the metal contact electrode 23 (i.e. the first sensing electrode in this step).
Of course, when the headset does not include the TP sensor module, it may be determined whether the headset is in the wearing state by detecting whether the capacitance variation amounts of the cap sensor4#, cap sensor 5# are all greater than the first preset threshold value in other manners.
In addition, since an Analog Switch (i.e., Analog Switch module) exists between the first pin of the serial port communication and the first sensing electrode of the serial port communication in this example, in order to disconnect the first pin from the first sensing electrode, the host controls the electrical frequency of the Analog Switch module. In other embodiments, when there is no analog switch between the first pin of the serial port communication and the first sensing electrode of the serial port communication, the disconnection between the first pin and the first sensing electrode may be implemented in other manners.
It is understood that the first pin (i.e., the UART _ TX pin and the UART _ RX pin are equivalently in a floating state) through step 101.
Optionally, step 102, determining whether the first sensing electrode receives a first touch input;
as shown in fig. 4, the first sensing electrode here is a metal contact electrode 23.
Optionally, in an embodiment, the wearable device further comprises a touch detector (i.e., TP sensor module of fig. 4) connected to the first sensing electrode; as shown in fig. 4, pin 25 of the TP sensor module is electrically connected to metal contact electrode 23.
Then in this embodiment, in executing step 102, a first driving signal may be sent to the first sensing electrode by the touch detector; acquiring, by the touch detector, a variation amount of a capacitance to ground of the first sensing electrode corresponding to the first driving signal; when the variation is larger than or equal to a preset threshold value, determining that the first sensing electrode receives a first touch input; when the variation is smaller than the preset threshold, it is determined that the first touch input is not received by the first sensing electrode.
As shown in fig. 4, the TP sensor module can charge the metal contact electrode 23 (i.e. send the first driving signal to the metal contact electrode 23), and the user is connected to the ground, and the user can suck part of the electric quantity when touching the metal contact electrode 23 of the ear stem base as an external conductor; therefore, the TP sensor module may obtain a first capacitance of the metal contact electrode 23 when the metal contact electrode 23 is charged, and obtain a second capacitance of the metal contact electrode 23 after the user touches, and obtain a difference between the two capacitances as a variation amount of the capacitance to ground of the first sensing electrode corresponding to the first driving signal. Then it may be determined that the metal contact electrode 23 received the first touch input when the amount of change is greater than or equal to, for example, a second preset threshold, and otherwise, the first touch input was not received.
In the embodiment of the invention, a pin is led out from a touch detector in the wearable device to be connected with a first sensing electrode for serial port communication, so that the variation of the capacitance to ground of the first sensing electrode can be detected through the touch detector, whether the first sensing electrode receives a first touch input is determined, the first sensing electrode can be used as a new capacitance sensor under the condition that the first sensing electrode is disconnected with a first pin for serial port communication, whether a second touch input received by a second sensing electrode is effective can be accurately judged based on whether the first sensing electrode receives the first touch input, the false touch probability of the touch function of the wearable device is reduced, and the experience of a user using the touch function is improved.
In this embodiment, the TP sensor module may multiplex the metal contact electrode 23 for serial communication as the cap sensor 6# of the headset.
Optionally, as shown in fig. 4, the touch detector is also electrically connected to the at least one second sensing electrode (i.e., the cap sensor1#, the cap sensor 2#, and the cap sensor 3 #).
103, when the first sensing electrode receives the first touch input and the at least one second sensing electrode receives a second touch input, performing a response operation on the second touch input;
in the method for determining whether the at least one second sensing electrode receives the respective second touch input in this step, referring to the method for determining whether the first sensing electrode receives the first touch input in the foregoing embodiment, the method is determined by using the capacitance-to-ground variation, and details are not repeated here.
The second sensing electrode here includes at least one of a cap sensor1#, a cap sensor 2#, and a cap sensor 3 #. For example, if the cap sensor1# receives the second touch input, and the related art separately determines whether the second touch input is received according to the capacitance variation of the cap sensor1#, which causes a problem of high false touch rate, in this embodiment, before responding to the second touch input, it is necessary to determine whether not only the second touch input to the cap sensor1# is received, but also the first touch input to the metal contact electrode 23 (i.e., the cap sensor 6#) is received, and if both the second touch input and the first touch input are received, the response operation is performed on the second touch input.
And 104, refusing to perform response operation on a second touch input under the condition that the first touch input is not received by the first sensing electrode and the second touch input is received by the at least one second sensing electrode.
In this embodiment, if at least one of the capacitive sensors cap sensor1#, cap sensor 2# and cap sensor 3# receives the second touch input, but the metal contact electrode 23 does not receive the first touch input, that is, the user only touches the touch area of the ear stem, and does not touch the touch area of the metal contact electrode 23 of the ear stem base, the TP sensor module does not report the second touch input to the host for a response operation, and it is considered that the touch event corresponding to the second touch input is invalid.
In the embodiment of the present invention, when it is detected that the wearable device is in a wearing state, the first sensing electrode is not in a serial communication state and the first pin is in a floating state by disconnecting the first sensing electrode for serial communication from the first pin, and then a response operation is performed on the second touch input only when it is determined that the first sensing electrode receives the first touch input and at least one second sensing electrode receives the second touch input by determining whether the first sensing electrode receives the first touch input or not; and under the condition that the first sensing electrode does not receive the first touch input and the at least one second sensing electrode receives the second touch input, the response operation of the second touch input is refused, so that the false touch rate of the touch function of the touch input of the second sensing electrode is reduced.
Specifically, the embodiment of the invention sets the UART _ TX pin and the UART _ RX pin to be in a suspended state by detecting whether the wearable device is in a wearing state or not; then, the TP sensor module charges the metal contact electrodes corresponding to the UART _ TX pin and the UART _ RX pin, and when a user touches the metal contact electrodes, part of electric quantity can be absorbed, so that the TP sensor module detects the variation of the capacitance to ground before and after the metal contact electrodes are touched by fingers, and when the variation is greater than or equal to a preset threshold, it is determined that the metal contact electrodes for serial port communication are touched, and conversely, it is determined that the metal contact electrodes are not touched; then the touch event received by the capacitive sensor on the ear stem is valid if the metal contact of the UART TX/RX is touched and invalid otherwise.
As can be seen from the above example of the earphone, the embodiment of the present invention is configured to detect whether there is a touch behavior by multiplexing the metal contact on the earphone base, and when the metal contact (i.e., the first sensing electrode) on the base (i.e., the base of the ear stem) detects an effective touch behavior and the second sensing electrode of the ear stem also detects a touch event, report the touch event to the host, otherwise, when the first sensing electrode on the base does not detect an effective touch behavior, not report the detected touch event of the second sensing electrode, so that a false touch rate of the earphone touch function can be reduced, and a user experience of using the earphone touch function is improved.
On the basis of any one of the above embodiments, referring to fig. 5, a flowchart of a touch control method according to another embodiment of the present invention is also shown.
The method is applied to a wearable device, wherein the wearable device comprises a first sensing electrode and a first pin for serial port communication, and at least one second sensing electrode; the wearable device further comprises a touch detector connected with the first sensing electrode;
the method comprises the following steps:
in an example, as shown in fig. 2 and 4, the TP sensor module (i.e., the touch detector) may determine whether the capacitance variation of the cap sensor4# and the cap sensor 5# are both greater than a first preset threshold (for a specific detection method, the above embodiment of determining whether the first sensing electrode receives the first touch input may be referred to, and details are not repeated here), and if not, determine that the earphone is not in the wearing state;
the TP sensor module can report information indicating that the earphone is not in a wearing state to the Host; the Host can then change the electrical frequency sent to the Analog Switch module, so that the Switch pin of the Analog Switch module is set to low (e.g. 0) and the Enable pin is set to low (e.g. 0), i.e. the two pins are in (0,0) states, so that the internal Switch of the Analog Switch module is connected, so that the UART _ TX pin (i.e. the first pin in this step) on the left side of fig. 4 is electrically connected to the metal contact electrode 23 (i.e. the first sensing electrode in this step), and the UART _ RX pin (i.e. the first pin in this step) is electrically connected to the metal contact electrode 23 (i.e. the first sensing electrode in this step). The UART _ TX pin and the UART _ RX pin and the metal contact electrode 23 are restored to the connection relationship before the operation of disconnecting the connections in step 101.
It should be noted that, before step 101 is executed, the electrical connection relationship between the UART _ TX pin, the UART _ RX pin and the metal contact electrode 23 may include 3 states, for example, state 1: the UART _ TX pin is electrically connected with the metal contact electrode 23, and the UART _ RX pin is disconnected with the metal contact electrode 23, namely, only a serial port is used for transmitting data; for example, state 2: the UART _ TX pin is disconnected from the metal contact electrode 23, and the UART _ RX pin is electrically connected with the metal contact electrode 23, namely, only a serial port is used for receiving data; state 3: the UART _ TX pin is electrically connected to the metal contact electrode 23, and the UART _ RX pin is electrically connected to the metal contact electrode 23, that is, only a serial port is used for transmitting and receiving data.
And the first pin in this step may be at least one of a uartx pin and a uarrx pin. Therefore, the connection relationship between the UART _ TX pin and the UART _ RX pin established in step 201 and the metal contact electrode 23 may be any one of the three states listed above. For example, to one of the three states described above before step 101 is performed.
In addition, in the case that it is detected that the wearable device is not in the wearing state, the TP sensor module may further set a second pin (i.e., pin 25 in fig. 4) of its own connected to the first sensing electrode (i.e., metal contact electrode 23) to a high impedance state, so as to avoid affecting normal data communication of the UART serial port.
The second pin is a pin of the TP sensor module, which is connected with the first sensing electrode.
In addition, the embodiment of the present invention does not limit an execution order between the step of establishing the connection between the first pin and the first sensing electrode and the step of setting the second pin of the touch detector connected to the first sensing electrode to a high resistance state, and both of them are executed in a case where it is detected that the wearable device is not in a worn state.
Preferably, the step of setting the second pin of the touch detector connected to the first sensing electrode to a high resistance state is performed before the step of establishing the connection between the first pin and the first sensing electrode. Therefore, the first sensing electrode can be timely ensured not to be interfered by the touch detector when the serial port communication function is used.
In the embodiment of the invention, under the condition that the wearable device is not detected to be in a wearing state, the connection between the first pin and the first sensing electrode is established, and the second pin of the touch detector connected with the first sensing electrode is set to be in a high-resistance state, so that the false touch rate triggered by the touch function of the second sensing electrode can be reduced without using the first sensing electrode, and the first sensing electrode can be recovered to be in a serial communication state, thereby realizing the flexible switching of different functions of the first sensing electrode; moreover, the second pin connected with the first sensing electrode is set to be in a high-impedance state, so that the interference of data transmission when the first sensing electrode is used for serial port communication to transmit data can be reduced.
The high-impedance state is a common term in a digital circuit, and refers to an output state of the circuit, which is neither high level nor low level, and has no influence on a next stage circuit if the high-impedance state is input into the next stage circuit, and like the high-impedance state, the high level or the low level is possible if the high-impedance state is measured by a multimeter, and the high level or the low level is determined according to what is connected behind the high-impedance state.
In electronics, a High impedance state (English: High impedance) indicates that a certain node in a circuit has a relatively higher impedance than other points in the circuit. This concept is involved in tristate logic, pull-up resistors.

In the embodiment of the invention, when the wearable device is not in a wearing state, the connection between the first pin and the first sensing electrode is established, and the second pin of the touch detector connected with the first sensing electrode is set to be in a high-resistance state, so that not only can the false touch rate triggered by the touch function of the second sensing electrode be reduced without using the first sensing electrode, but also the first sensing electrode can be restored to be in a serial communication state, and the flexible switching of different functions of the first sensing electrode is realized; moreover, the second pin connected with the first sensing electrode is set to be in a high-impedance state, so that the interference of data transmission when the first sensing electrode is used for serial port communication to transmit data can be reduced. Further, the embodiment of the present invention further rejects the response operation when the at least one second sensing electrode receives the second touch input, so that the detected touch events in this case are all regarded as invalid operations. The false touch probability of the touch function of the wearable device is reduced, and the experience of the user in using the touch function is improved.
In addition, as shown in fig. 4, when interaction is performed between the Host and the TP sensor module, the Host may control the operation of the TP sensor module through INT (interrupt signal); in addition, the TP sensor module may also send I2C (heartbeat instruction) to the Host to make the Host know that the TP sensor module is alive.
