Detailed ways

The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of them. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of this application.

In the process of realizing the present application, the inventor found that the working principle of the capacitive touch technology solution is that when the distance between the external conductor and the sensing electrode changes, the capacitance of the sensing electrode to the ground will change, so the finger (I.e., the external conductor) the touch operation of the touch sensing electrode area will be detected. Even if the touch action is unintentional, the solution will still determine that the touch operation is a valid touch input, thereby triggering the operation corresponding to the touch input. Therefore, the inventor found that the use of the sensing electrode for the touch function may easily lead to the problem of false touches, resulting in a higher rate of false touches of the touch function.

In order to solve the above technical problems and better realize the touch function of the wearable device, the embodiment of the present application aims to determine whether the touch action received by the sensing electrode is intentional or unintentional, so that when it is determined that the touch action is unintentional, Refuse to respond to the touch action to reduce 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 application is shown, which is applied to a wearable device, and the wearable device includes 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 (for example, AR (Augmented Reality) glasses), or a headset device.

The following description takes the wearable device as an earphone as an example for description. When the wearable device is a smart watch or smart glasses, the method is similar, and the following examples can be referred to, so it will not be repeated one by one.

In an example, FIG. 2 shows a schematic side view of the shape of the earphone; FIG. 3 shows a schematic diagram of the base 11 of the ear stem of FIG. 2.

Figure 2 shows five sensing electrodes (ie, a cap sensor). Among them, cap sensor 4# and cap sensor 5# are used to detect whether the earphone is in the wearing state; at least one second sensing electrode on the side wall of the ear stem includes cap sensor 1#, cap sensor 2#, and cap sensor 3# , The three second sensing electrodes can be used to implement touch operation functions such as single click, double click, long press, up and down, etc., to control audio.

As shown in Figure 3, the headset base has 3 sensing electrodes (here, metal contact electrodes), which are the metal contact electrodes 21 of VBUS (USB voltage (5V)), and GND (power ground, 0 level). The metal contact electrode 22, wherein the metal contact electrode 21 and the metal contact electrode 22 are used for earphone charging; in addition, the base also includes the metal contact electrode 23 for serial communication (that is, the first Sensing electrode), where the metal contact electrode 23 is a metal contact electrode of UART (Universal Asynchronous Receiver/Transmitter)_TX (transport)/RX (receive). When the metal contact electrode 23 is used for UART communication, it can be used to transfer data to upgrade the earphone system or analyze problems.

In the embodiment of the present application, the metal contact electrode 23 of UART_TX/RX can be reused as the cap sensor6# of the earphone.

Continuing to refer to FIG. 4, the circuit connection relationship between the various modules of the earphone in the above-mentioned embodiment of the present application is shown.

The headset may include a headset host terminal (ie, the Host in FIG. 4), a touch detector (ie, the TP sensor module in FIG. 4), and an analog switch module for serial communication (ie, the Analog Switch module in FIG. 4).

As shown in Figure 4, the five pins of the TP sensor module are respectively connected to cap sensor 1#, cap sensor 2# and cap sensor 3#, cap sensor 4#, and cap sensor 5# in Figure 2 above.

In Figure 4, the two pins on the left side of the Analog Switch module are the UART_TX pin and the UART_RX pin, which are electrically connected to the host; there is a pin 24 on the right side of the Analog Switch module as shown in Figure 3. The metal contact electrode 23 is electrically connected. In addition, the Analog Switch module also has a Switch pin and an Enable pin, which are not shown.

In addition, as shown in FIG. 4, the embodiment of the present application further leads to a pin 25 from the TP sensor module to be electrically connected to the metal contact electrode 23 in FIG. 3.

The host can set the Switch pin and Enable pin of the Analog Switch module to different states by controlling the power frequency input to the Analog Switch module. As a result, the internal switch of the Analog Switch module for serial communication is in a closed or open state, so that the metal contact electrode 23 can communicate with the pin 25 of the TP sensor module, or the metal contact electrode 23 can communicate with the pin 25 of the Analog Switch module. UART_TX pin and UART_RX pin are used for communication.

Based on the foregoing Figures 2 to 4, the process described in the embodiment of the present application is described in detail, and the process includes the following steps:

Step 101: When it is detected that the wearable device is in a wearing state, disconnect the connection between the first pin and the first sensing electrode;

In an example, as shown in Figures 2 and 4, the TP sensor module can detect whether the capacitance changes of cap sensor 4# and cap sensor 5# are both greater than the first preset threshold (for specific detection methods, refer to the judgment The following embodiments of whether the first sensing electrode receives the first touch input will not be repeated here.) If yes, it is determined that the headset is in the wearing state; the TP sensor module can report the information indicating that the headset is in the wearing state to the Host; then Host can change the power frequency sent to the Analog Switch module, so that the Switch pin of the Analog Switch module is set to high (for example, 1), and the Enable pin is set to high (for example, 1), that is, the two pins above The status is (1,1), so that the internal switch of the Analog Switch module is turned off, thereby disconnecting the UART_TX pin and UART_RX pin on the left side of Figure 4 (that is, the first step in this step). The pin) is an electrical connection with the metal contact electrode 23 (that is, the first sensing electrode in this step).

Of course, when the headset does not include the TP sensor module, other methods can be used to detect whether the capacitance changes of cap sensor 4# and cap sensor 5# are both greater than the first preset threshold, so as to determine whether the headset is in the wearing state.

In addition, since in this example, there is an analog switch (ie Analog Switch module) between the first pin of serial communication and the first sensing electrode of serial communication, therefore, in order to disconnect the first pin from the first sensing electrode, The connection between the sensing electrodes is realized by the host controlling the electrical frequency of the Analog Switch module. In other embodiments, when there is no analog switch between the first pin of serial communication and the first sensing electrode of serial communication, the disconnection between the first pin and the first sensing electrode can be realized by other methods. Open the connection.

It can be understood that, after step 101, the first pin (that is, the UART_TX pin and the UART_RX pin are equivalent to being in a floating state).

Optionally, in step 102, it is determined whether the first sensing electrode receives the first touch input;

As shown in FIG. 4, the first sensing electrode here is a metal contact electrode 23.

Optionally, in one embodiment, the wearable device further includes a touch detector (that is, the TP sensor module of FIG. 4) connected to the first sensing electrode; as shown in FIG. 4, the tube of the TP sensor module The pin 25 is electrically connected to the metal contact electrode 23.

Then, in this embodiment, when step 102 is performed, the first driving signal may be sent to the first sensing electrode through the touch detector; the first driving signal corresponding to the first driving signal may be acquired through the touch detector. The amount of change in the capacitance to ground of the first sensing electrode; when the amount of change is greater than or equal to the preset threshold, it is determined that the first sensing electrode receives the first touch input; when the amount of change is less than According to the preset threshold, it is determined that the first sensing electrode has not received the first touch input.

As shown in Figure 4, the TP sensor module can charge the metal contact electrode 23 (that is, send the first driving signal to the metal contact electrode 23), and the user is connected to the earth, and the user acts as an external conductor when touching the earstalk base When the metal contact electrode 23 is used, part of the electricity can be absorbed; therefore, the TP sensor module can obtain the first capacitance of the metal contact electrode 23 when the metal contact electrode 23 is charged, and obtain the first capacitance of the metal contact electrode 23 after the user touches it. The second capacitance of the metal contact electrode 23 is taken as the change in the capacitance to ground of the first sensing electrode corresponding to the first driving signal by obtaining the difference between the two capacitances the amount. Then, when the amount of change is greater than or equal to, for example, the second preset threshold, it can be determined that the metal contact electrode 23 has received the first touch input, on the contrary, the first touch input has not been received.

In the embodiment of the present application, the touch detector in the wearable device is connected to the first sensing electrode for serial communication by leading out a pin, so that the touch detector can be used to detect the first sensing electrode. The amount of change in the capacitance to ground to determine whether the first sensing electrode receives the first touch input, and the first sensing electrode can be disconnected from the first pin of the serial port communication when the first sensing electrode is disconnected. The measuring electrode is used as a new capacitive sensor, so that it can accurately determine whether the second touch input received by the second sensing electrode is valid based on whether the first sensing electrode receives the first touch input, thereby reducing the wearable device’s performance. The false touch probability of the touch function, and enhance the user's experience of using the touch function.

In this embodiment, the TP sensor module can reuse the metal contact electrode 23 used 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 (that is, the cap sensor 1#, the cap sensor 2#, and the cap sensor 3# are connected).

Step 103: When the first sensing electrode receives the first touch input and the at least one second sensing electrode receives a second touch input, perform a response operation to the second touch input ；

For the method of determining whether the at least one second sensing electrode receives the respective second touch input in this step, refer to the above-mentioned embodiment. The method for whether the first sensing electrode receives the first touch input is all based on It is determined by the amount of capacitance change to ground, so I won’t repeat them here.

The second sensing electrode here includes at least one of cap sensor 1#, cap sensor 2#, and cap sensor 3#. For example, if cap sensor 1# receives the second touch input, the related technology alone determines whether the second touch input is received based on the capacitance change of cap sensor 1#. There is a problem of high false touch rate. Then in this embodiment Before responding to the second touch input, it is necessary to determine whether not only the second touch input to cap sensor 1# is received, but also the first touch to the metal contact electrode 23 (ie cap sensor 6#) is received Only when all inputs are received, a response operation to the second touch input is performed.

Step 104: In a case where the first sensing electrode does not receive the first touch input and the at least one second sensing electrode receives a second touch input, refuse to perform the second touch input Respond to operation.

In this embodiment, if at least one of cap sensor 1#, 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 If only the touch area of the earstalk is touched, but the touch area where the metal contact electrode 23 of the earstalk base is not touched, the TP sensor module will not report the second touch input to the host for a response operation, and consider the second touch The touch event corresponding to the input is invalid.

In the embodiment of the present application, when it is detected that the wearable device is in a wearing state, the connection between the first sensing electrode and the first pin for serial communication is disconnected, so that the first sensing electrode It is not in the state of serial communication and the first pin is in the floating state, then by determining whether the first sensing electrode receives the first touch input, it is determined that the first sensing electrode has received the first touch input, and at least one first The second sensing electrode will respond to the second touch input only when it receives the second touch input; while the first sensing electrode does not receive the first touch input, and at least one second sensing electrode receives In the case of the second touch input, the response operation to the second touch input is rejected, which reduces the false touch rate of the touch function of the touch input to the second sensing electrode.

Specifically, the embodiment of the application detects whether the wearable device is in the wearing state, and in the wearing state, sets the UART_TX pin and the UART_RX pin to a floating state; then, the TP sensor module corresponds to the UART_TX pin and the UART_RX pin. The metal contact electrode is charged. When the user touches the metal contact electrode, part of the electricity can be absorbed. Therefore, the TP sensor module detects the change of the capacitance to ground before and after the finger touches the metal contact electrode. When the amount of change is greater than or equal to the preset threshold, it is determined that the metal contact electrode used for serial communication is touched. On the contrary, it is determined that the metal contact electrode is not touched; then the metal contact of UART TX/RX is touched. In the case of touch, the touch event received by the capacitive sensor on the ear handle is valid, otherwise it is invalid.

Combining the above examples of earphones, it can be seen that the embodiment of the present application reuses the metal contacts on the earphone base to detect whether there is a touch behavior. When the metal contacts on the base (the base of the earstalk) (that is, the first sense) (Measurement electrode) When a valid touch behavior is detected and the second sensing electrode of the earstalk also detects a touch event, the touch event will be reported to the host. Conversely, when the first sensing electrode on the base does not detect a valid touch event. For touch behavior, the detected touch event of the second sensing electrode is not reported, thereby reducing the false touch rate of the earphone touch function and improving the user's experience of using the earphone touch function.

On the basis of any one of the foregoing embodiments, referring to FIG. 5, a flowchart of a touch control method according to another embodiment of the present application is also shown.

The method is applied to a wearable device. The wearable device includes a first sensing electrode and a first pin for serial communication, and at least one second sensing electrode; the wearable device also includes a communication with the first sensing electrode. Electrode connected touch detector;

The method includes the following steps:

Step 201: In the case that it is detected that the wearable device is not in a wearing state, establish a connection between the first pin and the first sensing electrode, and connect the first pin to the first sensing electrode. The second pin of the touch detector is set to a high impedance state;

In an example, as shown in Figures 2 and 4, the TP sensor module (ie touch detector) can detect whether the capacitance changes of cap sensor 4# and cap sensor 5# are both greater than the first preset threshold (specific detection The method can refer to the above-mentioned embodiment of determining whether the first sensing electrode receives the first touch input, which will not be repeated here.), if not, determine that the headset is not in a wearing state;

The TP sensor module can report the information that the headset is not in the wearing state to the Host; then the Host can change the electrical frequency sent to the Analog Switch module, so that the Switch pin of the Analog Switch module is set to low (for example, 0), and the Enable tube Set the pin to low (for example, 0), that is, the state of the above two pins is (0,0), so that the internal switch of the Analog Switch module is connected, so that the UART_TX pin on the left side of Figure 4 (that is, The first pin in this step) is electrically connected to the metal contact electrode 23 (that is, the first sensing electrode in this step), and the UART_RX pin (also the first pin in this step) and The metal contact electrodes 23 (that is, the first sensing electrode in this step) are electrically connected. The UART_TX pin and the UART_RX pin and the metal contact electrode 23 are restored to the connection relationship before the disconnection operation of step 101.

It should be noted that before performing step 101, the electrical connection relationship between the UART_TX pin, the UART_RX pin and the metal contact electrode 23 may include three states, for example, state 1: the UART_TX pin and the metal contact electrode 23 Electrical connection between the UART_RX pin and the metal contact electrode 23 is disconnected, that is, only the serial port is used to send data; for example, state 2: the UART_TX pin is disconnected from the metal contact electrode 23, and the UART_RX pin is disconnected from the metal contact electrode 23. The point electrodes 23 are electrically connected, that is, only the serial port is used to receive 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 Use the serial port to send data and receive data.

The first pin in this step may be at least one of the UART_TX pin and the UART_RX 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 can be any one of the three states listed above. For example, it is restored to one of the above three states that it was in before step 101 was executed.

In addition, in the case of detecting that the wearable device is not in the wearing state, the TP sensor module can also connect its second pin connected to the first sensing electrode (ie, the metal contact electrode 23) (ie, in Figure 4). The pin 25) is set to a high-impedance state, so as not to affect the normal data communication of the UART serial port.

Wherein, the second pin is a pin of the TP sensor module that establishes a connection with the first sensing electrode.

In addition, in the embodiment of the present application, the step of establishing the connection between the first pin and the first sensing electrode is connected to the second tube of the touch detector connected to the first sensing electrode. The execution sequence between the steps of setting the feet to the high impedance state is not limited, and they are all executed when it is detected that the wearable device is not in the wearing state.

Optionally, in the step of setting the second pin of the touch detector connected to the first sensing electrode to a high impedance state, the first pin and the first sensing electrode are established as described above. The steps between the connections are performed before. In this way, it can be ensured in time that when the serial port communication function is used, the first sensing electrode is not interfered by the touch detector.

In the embodiment of the present application, when it is detected that the wearable device is not in the wearing state, the connection between the first pin and the first sensing electrode is established, and the connection between the first pin and the first sensing electrode is established. The second pin of the touch detector connected to the electrode is set to a high-impedance state, which can not only reduce the false touch rate of triggering the touch function of the second sensing electrode without using the first sensing electrode, but also The first sensing electrode can be restored to the state of serial communication, realizing flexible switching of different functions of the first sensing electrode; moreover, by setting the second pin connected to the first sensing electrode to a high impedance state Therefore, it is possible to reduce the interference to the data transfer when the first sensing electrode is used for serial communication to transfer data.

The high-impedance state is a common term in digital circuits. It refers to an output state of the circuit, which is neither high nor low. If the high-impedance state is input to the next level circuit, there is nothing to the next level circuit. The impact is the same as if it is not connected. If it is measured with a multimeter, it may be high or low, depending on what is connected behind it.

In electronics, the high impedance state (English: High impedance) means that a node in the circuit has a relatively higher impedance than other points in the circuit. This concept is involved in tri-state logic and pull-up resistors.

Optionally, after step 201, the method according to the embodiment of the present application may further include:

Step 202: When the at least one second sensing electrode receives the second touch input, refuse to respond to the second touch input.

In an example, as shown in FIGS. 2 and 4, at least one second sensing electrode, for example, at least one capacitive sensor of cap sensor 1#, cap sensor 2#, and cap sensor 3# receives the second touch input, Then the TP sensor module may not report the second touch input to the host to achieve the purpose of refusing to respond to the second touch input.

In the embodiment of the present application, when the wearable device is not in the wearing state, by establishing a connection between the first pin and the first sensing electrode, and connecting with the first sensing electrode The second pin of the touch detector is set to a high-impedance state, which can not only reduce the false touch rate triggered by the touch function of the second sensing electrode without using the first sensing electrode, but also The first sensing electrode returns to the state of serial communication, realizing flexible switching of different functions of the first sensing electrode; moreover, by setting the second pin connected to the first sensing electrode to a high impedance state, It can reduce the interference of data transmission when the first sensing electrode is used for serial communication to transmit data. Further, the embodiment of the present application also rejects the response operation to the second touch input received by the at least one second sensing electrode, so that all touch events detected in this case are regarded as invalid operations. The probability of false touches of the touch function of the wearable device is reduced, and the user experience of using the touch function is improved.

In addition, as shown in Figure 4, when the Host interacts with the TP sensor module, the Host can control the work of the TP sensor module through INT (interrupt signal); in addition, the TP sensor module can also send I2C (heartbeat commands) to Host, to make the Host know that the TP sensor module is alive.
