Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The inventor finds that in the process of implementing the invention, the working principle of the capacitive touch control technical scheme is that when the distance between the external conductor and the sensing electrode is changed, the change of the capacitance of the sensing electrode to the ground is caused, so that the touch control operation of a finger (namely the external conductor) touching the sensing electrode area is detected. Even if the touch action is unintentional, the scheme still judges that the touch operation is a valid touch input, so that the operation corresponding to the touch input is triggered. Therefore, the inventor finds that the problem of false touch is easily caused by using the sensing electrode as the touch function, so that the false touch rate of the touch function is high.
In order to solve the technical problem, the embodiment of the invention aims to better realize the touch function of the wearable device, and aims to judge whether the touch action received by the sensing electrode is intentional or unintentional, so that when the unintentional touch action is determined, the response to the touch action is refused, and the false touch rate of the touch control function is reduced.
In particular, referring to fig. 1, a flowchart of a touch control method of one embodiment of the present invention is shown applied to a wearable device including a first sensing electrode and a first pin for serial communication, and at least one second sensing electrode.
The wearable device may be a smart watch, or a smart glasses (e.g., AR (Augmented Reality, augmented reality) glasses), or a headset device.
The wearable device is taken as an earphone for illustration, and when the wearable device is a smart watch or smart glasses, the method is similar, and the following examples are referred to, so that the description is omitted.
In one example, fig. 2 shows a side schematic view of the earphone profile; fig. 3 shows a schematic view of the base 11 of the earstem of fig. 2.
Fig. 2 shows 5 sensing electrodes (i.e., capacitive sensors). The cap sensor 4# and the cap sensor 5# are used for realizing a detection function of whether the earphone is in a wearing state or not; the at least one second sensing electrode of the side wall of the earstem comprises a cap sensor 1#, a cap sensor 2# and a cap sensor 3#, and the three second sensing electrodes can be used for realizing touch operation functions such as clicking, double clicking, long pressing, sliding up and down and the like for controlling audio.
As shown in fig. 3, the headset base has 3 sensing electrodes (here, metal contact electrodes), metal contact electrodes 21 of VBUS (USB voltage (5V)), metal contact electrodes 22 of GND (power ground, 0 level), respectively, wherein the metal contact electrodes 21 and the metal contact electrodes 22 are used for headset charging; in addition, the base further includes a metal contact electrode 23 for serial communication (i.e., the first sensing electrode for serial communication described above), where the metal contact electrode 23 is a metal contact electrode of UART (universal asynchronous receiver Transmitter, universal Asynchronous Receiver/Transmitter) _tx (transmit)/RX (receive). The metal contact electrode 23 can be used for transmitting data to upgrade a headset system or analyze problems, etc. when used for UART communication.
In the embodiment of the present invention, the metal contact electrode 23 of uart_tx/RX may be multiplexed as the cap sensor 6# of the earphone.
With continued reference to fig. 4, the circuit connection relationship between the individual modules of the earphone of the above embodiment of the present invention is shown.
The headset may include a headset Host (i.e., the Host of fig. 4), a touch detector (i.e., the TP sensor module of fig. 4), and an Analog Switch module for serial communication (i.e., the Analog Switch module of fig. 4).
As shown in fig. 4, the 5 pins of the TP sensor module are connected to the above-described cap sensor 1#, cap sensor 2# and cap sensor 3#, cap sensor 4#, and cap sensor 5# in fig. 2, respectively.
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, which are electrically connected to the host; the right side of the Analog Switch module has one pin 24 electrically connected to the metal contact electrode 23 in fig. 3. In addition, the Analog Switch module also has a Switch pin and an Enable pin, which are not shown, inside.
In addition, as shown in fig. 4, a pin 25 is also led out from the TP sensor module to be electrically connected with the metal contact electrode 23 in fig. 3.
The host computer can Enable the Switch pin and the Enable pin of the Analog Switch module to be in different states by controlling the electric frequency of the Analog Switch module. So that the internal Switch of the Analog Switch module for serial communication is in a closed or open state, thereby enabling the metal contact electrode 23 to communicate with the pin 25 of the TP sensor module, or the metal contact electrode 23 communicates with the uart_tx pin, uart_rx pin of the Analog Switch module.
The flow according to the embodiment of the present invention will be described in detail based on the above-described fig. 2 to 4, and the flow includes the following steps:
Step 101, under the condition that the wearing equipment is detected to be in a wearing state, disconnecting the first pin from the first sensing electrode;
in an example, as shown in fig. 2 and fig. 4, the TP sensor module may determine that the earphone is in a wearing state by detecting whether the capacitance variation amounts of the cap sensor 4# and the cap sensor 5# are both greater than a first preset threshold (the specific detection method may refer to the following embodiment for determining whether the first sensing electrode receives the first touch input, which is not described herein again); the TP sensor module can report the information indicating that the earphone is in a wearing state to a Host; then Host can 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), i.e., the states of the two pins are (1, 1), so that the internal Switch of the Analog Switch module is turned off, thereby disconnecting the electrical connection between the two pins uart_tx pin, uart_rx pin on the left side of fig. 4 (i.e., the first pin in this step) and the metal contact electrode 23 (i.e., the first sensing electrode in this step).
Of course, when the earphone does not include the TP sensor module, whether the capacitance variation amounts of the cap sensor 4# and the cap sensor 5# are both greater than the first preset threshold may be detected in other manners, so as to determine whether the earphone is in a wearing state.
Further, since in the present example, there is an Analog Switch (i.e., analog Switch module) between the first pin of the serial port communication and the first sensing electrode of the serial port communication, in order to disconnect the connection between the first pin and the first sensing electrode, this is achieved by a manner that 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, then disconnection between the first pin and the first sensing electrode may be achieved by other means.
It is understood that the first pins (i.e., uart_tx pin and uart_rx pin are equivalent to being in a floating state) via 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 one embodiment, the wearable device further comprises a touch detector (i.e., the TP sensor module of fig. 4) connected to the first sensing electrode; as shown in fig. 4, pins 25 of the TP sensor module are electrically connected to the metal contact electrodes 23.
Then in this embodiment, when step 102 is performed, a first drive signal may be sent to the first sense electrode by the touch detector; acquiring a change amount of capacitance to ground of the first sensing electrode corresponding to the first driving signal through the touch detector; when the variation is greater than or equal to a preset threshold, determining that the first sensing electrode receives a first touch input; and when the variation is smaller than the preset threshold value, determining that the first sensing electrode does not receive the first touch input.
As shown in fig. 4, the TP sensor module may charge the metal contact electrode 23 (i.e., send a first driving signal to the metal contact electrode 23), and the user is connected to the ground, and when touching the metal contact electrode 23 of the ear handle base, the user may suck a part of the electric quantity as an external conductor; accordingly, the TP sensor module may acquire a first capacitance of the metal contact electrode 23 when charging the metal contact electrode 23, and acquire a second capacitance of the metal contact electrode 23 after a user touches, by acquiring a difference between the two capacitances as a change amount of the capacitance to ground of the first sensing electrode corresponding to the first driving signal. Then when the amount of change is greater than or equal to, for example, a second preset threshold, it may be determined that the metal contact electrode 23 received the first touch input, and conversely, the first touch input was not received.
In the embodiment of the invention, the touch detector in the wearable device is led out of one pin to be connected with the first sensing electrode for serial communication, so that the change of the capacitance to ground of the first sensing electrode can be detected through the touch detector, whether the first sensing electrode receives the 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 the first pin for serial communication, and whether the second touch input received by the second sensing electrode is effective can be accurately judged based on whether the first sensing electrode receives the first touch input or not, thereby reducing the false touch probability of the touch function of the wearable device and improving the experience of a user using the touch function.
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., cap sensor 1#, cap sensor 2# and cap sensor 3# connections).
Step 103, in a case that 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;
The method for determining whether the at least one second sensing electrode receives the respective second touch input in this step may refer to the method for determining whether the first sensing electrode receives the first touch input in the above embodiment, which is determined by means of the capacitance-to-ground variation, and will not be described in detail herein.
The second sensing electrode herein includes at least one of cap sensor 1#, cap sensor 2# and cap sensor 3 #. For example, if the second touch input is received by the cap sensor 1#, in the related art, whether the second touch input is received is determined based on the capacitance variation of the cap sensor 1#, and there is a problem of high false touch rate.
Step 104, refusing to respond to the second touch input when 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 capacitance sensors of the cap sensor 1#, the cap sensor 2# and the 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 touches only the touch area of the ear handle, but does not touch the touch area where the metal contact electrode 23 of the ear handle base is located, the TP sensor module does not report the second touch input to the host for a response operation, and considers that the touch event corresponding to the second touch input is invalid.
In the embodiment of the invention, when the wearing equipment is detected to be in the wearing state, the first sensing electrode is disconnected from the first pin, so that the first sensing electrode is not in the serial port communication state, and the first pin is in the suspension state, then if the first sensing electrode receives the first touch input, the second sensing electrode is determined to receive the first touch input, and the second sensing electrode receives the second touch input, then the second touch input is responded; and under the condition that the first sensing electrode does not receive the first touch input and at least one second sensing electrode receives the second touch input, the response operation on the second touch input is refused, and the error touch rate of the touch control function of the touch input of the second sensing electrode is reduced.
Specifically, in the embodiment of the invention, whether the wearing equipment is in the wearing state is detected, and in the wearing state, the UART_TX pin and the UART_RX pin are set to be in a suspended state; then, the TP sensor module charges metal contact electrodes corresponding to the UART_TX pin and the UART_RX pin, when a user touches the metal contact electrodes, partial electric quantity can be absorbed, so that the TP sensor module detects the change of capacitance to ground before and after a finger touches the metal contact electrodes on the metal contact electrodes, when the change is larger than or equal to a preset threshold value, the metal contact electrodes for serial communication are determined to be touched, and conversely, the metal contact electrodes are determined to not be touched; then the touch event received by the capacitive sensor on the ear stem is only valid in case the metallic contact of UART TX/RX is touched, otherwise not valid.
As can be seen from the above examples of the earphone, in the embodiment of the present invention, by multiplexing the metal contacts on the earphone base to detect whether there is a touch action, when the metal contacts (i.e., the first sensing electrodes) on the base (the base of the ear handle) detect an effective touch action and the second sensing electrodes of the ear handle also detect a touch event, the touch event is reported to the host, otherwise, when the first sensing electrodes on the base do not detect an effective touch action, the touch event detected by the second sensing electrodes is not reported, so that the false touch rate of the earphone touch function can be reduced, and the experience of using the earphone touch function by the user 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 communication, and at least one second sensing electrode; the wearable device further includes a touch detector connected to the first sensing electrode;
the method comprises the following steps:
step 201, when it is detected that the wearable device is not in a wearing state, establishing a connection between the first pin and the first sensing electrode, and setting a second pin of the touch detector connected with the first sensing electrode to a high-resistance state;
in an example, as shown in fig. 2 and fig. 4, the TP sensor module (i.e. the touch detector) may detect whether the capacitance variation amounts of the cap sensor 4# and the cap sensor 5# are both greater than a first preset threshold (the specific detection method may refer to the above embodiment for determining whether the first sensing electrode receives the first touch input, which is not described herein, and if not, it is determined 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 a Host; the Host may then change the electrical frequency sent to the Analog Switch module such that the Switch pin of the Analog Switch module is set low (e.g., 0) and the Enable pin is set low (e.g., 0), i.e., the states of the two pins are (0, 0), such that the internal Switch of the Analog Switch module is connected such that the UART TX pin on the left side of fig. 4 (i.e., the first pin in this step) is electrically connected with the metal contact electrode 23 (i.e., the first sense electrode in this step), and the UART RX pin (also the first pin in this step) is electrically connected with the metal contact electrode 23 (i.e., the first sense electrode in this step). So that the uart_tx pin and the uart_rx pin are restored to the connection relationship before the operation of disconnection of step 101 with the metal contact electrode 23.
It should be noted that, before step 101 is performed, 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 with 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, i.e., only serial ports are used for transmitting data and receiving data.
And the first pin in this step may be at least one of a uart_tx pin and a uart_rx pin. Accordingly, 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 prior to execution of step 101.
In addition, when 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) connected to the first sensing electrode (i.e. the metal contact electrode 23) 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 which establishes connection with the first sensing electrode.
In addition, the embodiment of the present invention does not limit the execution sequence 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 they are all executed when it is detected that the wearable device is not in a wearing 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 a connection between the first pin and the first sensing electrode. Thus, the first sensing electrode is not interfered by the touch detector when the serial port communication function is used.
In the embodiment of the invention, under the condition that the wearing equipment is not in the wearing state, by establishing the connection between the first pin and the first sensing electrode and setting the second pin of the touch detector connected with the first sensing electrode to be in a high-resistance state, 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 restored to be in a serial communication state, so that the flexible switching of different functions of the first sensing electrode is realized; in addition, the second pin connected with the first sensing electrode is set to be in a high-resistance state, so that interference on data transmission when the first sensing electrode is used for serial communication data transmission can be reduced.
The high impedance state is a term commonly used in digital circuits and refers to an output state of the circuit, which is neither high nor low, and has no effect on the next stage if the high impedance state is input into the next stage, as is the case if the high impedance state is measured with a multimeter, and is possibly high or low, and is followed by something that follows.
In electronics, a High impedance state (english) indicates that a certain node in a circuit has a relatively higher impedance than other points in the circuit. This concept is involved in tri-state logic, pull-up resistors.
Optionally, after step 201, the method according to an embodiment of the present invention may further include:
step 202, refusing to respond to the second touch input under the condition that the at least one second sensing electrode receives the second touch input.
In one example, as shown in fig. 2 and 4, if 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 a second touch input, the TP sensor module may not report the second touch input to the host to reject the second touch input for responding operation.
In the embodiment of the invention, when the wearable device is not in the wearing state, by establishing the connection between the first pin and the first sensing electrode and setting the second pin of the touch detector connected with the first sensing electrode to be in a high-resistance state, 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 restored to be in a serial communication state, so that the flexible switching of different functions of the first sensing electrode is realized; in addition, the second pin connected with the first sensing electrode is set to be in a high-resistance state, so that interference on data transmission when the first sensing electrode is used for serial communication data transmission can be reduced. Further, the embodiment of the present invention further receives the second touch input rejection response operation to the at least one second sensing electrode, thereby treating the touch event detected in this case as an invalid operation. The false touch probability of the touch function of the wearable device is reduced, and the experience of the user using the touch function is improved.
In addition, as shown in fig. 4, when the Host interacts with the TP sensor module, the Host may control the operation of the TP sensor module through an INT (interrupt signal); in addition, the TP sensor module may also send an I2C (heartbeat command) to the Host to make the Host aware that the TP sensor module is in a surviving state.
