Detailed Description

Illustrative embodiments of the present application include, but are not limited to, a method of directionally controlling an electronic device, and a readable medium to solve a problem of difficulty in controlling a specific smart device in an environment where a plurality of smart devices exist.

It will be understood that, as used herein, the terms "first," "second," and the like may be used herein to describe various elements, but these elements should not be limited by these terms unless otherwise specified. These terms are only used to distinguish one element from another.

Embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Some current solutions can implement response control on a smart device through sound intensity, a tag, a combination of sound intensity and a tag, and the like, but these solutions still have possible interference, so that the responding smart device is not a smart device desired by a user, and accurate control on the smart device is difficult to implement. As shown in fig. 2(a), a scheme of implementing response control on a smart device through sound intensity is shown, in the scenario shown in fig. 2(a), a user desires that a smart television with a longer distance and a smaller pickup sound intensity responds, and a voice instruction issued by the user is actually responded by a smart speaker with a shorter distance and a larger pickup sound intensity, so that user experience is affected. For another example, fig. 2(B) shows a scheme of implementing response control on a smart device through a tag, in the scenario shown in fig. 2(B), a user wants to respond by one of the sound box a or the sound box B, and since the sound box a and the sound box B belong to the same type of smart device and the corresponding tags are the same, a voice command issued by the user is actually responded by the sound box a and the sound box B having the same tags, and there is also a problem in user experience. Fig. 2(c) shows a scheme of implementing response control on the smart device by combining sound intensity and tags, in the scenario shown in fig. 2(c), a user wants to respond by one of the sound box a or the sound box B, and the sound intensities received by the sound box a and the sound box B with the same tag are similar in the case of being at a distance from the user, so that the voice command issued by the user is actually still responded by the sound box a and the sound box B, and the user experience is also affected.

FIG. 3 illustrates a scenario 10 of an orientation control electronic device, according to some embodiments of the present application. Specifically, as shown in fig. 3, a first electronic device 100, a second electronic device 200, and a third electronic device 300 are included in this scenario 10. Wherein, when the user wants to perform voice interaction with the second electronic device 200 through the voice instruction, the first electronic device 100 may be pointed at the second electronic device 200. The first electronic device 100 can calculate device angles between the first electronic device 100 and the second electronic device 200 and the third electronic device 300 respectively according to the wireless broadcast signals sent by the second electronic device 200 and the third electronic device 300, where, as shown in fig. 8, the device angle between the first electronic device 100 and the second electronic device 200 is an angle between an antenna array surface of the first electronic device 100 and the received wireless broadcast signal sent by the second electronic device 200, and the device angle between the first electronic device 100 and the third electronic device 300 is an angle between the antenna array surface of the first electronic device 100 and the received wireless broadcast signal sent by the third electronic device 300.

When the user points the first electronic device 100 at the second electronic device 200, the first electronic device 100 detects that the device angle with the second electronic device 200 is 95 ° and the angle with the third electronic device 300 is 15 °. The first electronic device 100 transmits the device identification AOA ID2 of the second electronic device 200 included in the received wireless broadcast signal transmitted by the second electronic device 200 as the first device identification, and includes the first device identification in the second wireless broadcast signal. After receiving the second wireless broadcast signal, the second electronic device 200 compares its own device identifier with the first device identifier in the second wireless broadcast signal, and if the comparison is the same, the second electronic device 200 performs a corresponding voice response to the voice command of the user. The third electronic device 300 does not perform a voice response to the voice command of the user number because the device identifier of the third electronic device 300 is different from the first device identifier in the received second wireless broadcast signal.

In this way, in the embodiment of the present application, the user can designate the second electronic device 200 to respond to the voice command of the user by pointing the first electronic device 100 to the second electronic device 200 that desires to respond, and the third electronic device 300 that the user does not designate through the first electronic device 100 does not respond to the voice command of the user even if the user receives the voice command, so that the user can precisely control the electronic device that the user desires to respond to.

It can be understood that the technical solution of the present application is not only suitable for voice interaction, but also suitable for video interaction, for example, when the first electronic device 100 points to the second electronic device 200, the user issues an instruction to ask for weather by using a shaking gesture.

Referring to the scenario in fig. 4, taking the first electronic device 100 as a mobile phone, the second electronic device 200 as a sound box, and the third electronic device 300 as a television, as shown in fig. 4(a), the user points the mobile phone 100 at the television 300 and sends a voice control command "the baby art, i want to watch the baby pig, because the device angle between the television 300 and the mobile phone 100 satisfies the preset condition, even if the user is closer to the sound box 200 and farther from the television 300, the television 300 performs a voice response" well, and plays the baby pig, which is called "for your watching the baby" now, and performs subsequent response processing, thereby overcoming the problem of the conventional sound intensity scheme. Taking the second electronic device 200 as the sound box a and the fourth electronic device 201 added in the scene as the sound box B for further explanation, as shown in fig. 4(B), the user points the mobile phone 100 to the sound box a 200 and issues a voice instruction, "how is the day of the art, how is today? Because the device angle between the speaker a 200 and the mobile phone 100 satisfies the preset condition, even though the speaker a 200 and the speaker B201 are the same type of electronic device, the speaker a 200 performs voice response "weather XX, temperature XX" to the user voice command, thereby overcoming the problem that the speaker a and the speaker B respond to the user voice command simultaneously in the existing label scheme.

In addition, the drawing may include not only two electronic devices but also more than two electronic devices. For example, in the scenario shown in fig. 4(c), a second electronic device 200, a fourth electronic device 201, and a third electronic device 300 may be included. Further, taking the second electronic device 200 as the sound box a, the fourth electronic device 201 as the sound box B, and the third electronic device 300 as the television as an example, as shown in fig. 4(c), the user points the mobile phone 100 to the sound box a 200 and sends a voice control instruction, "a feature art, how today? Because the device angle between the sound box a 200 and the mobile phone 100 meets the preset condition, even though the television 300 is closer, the sound box a 200 and the sound box B201 are farther, and the sound box a 200 and the sound box B201 are the same type of electronic device, the sound box a 200 performs voice response to the voice command of the user, namely 'today weather XX, temperature XX', so that the problem that the sound box a 200 and the sound box B201 simultaneously respond to the voice command of the user in the existing sound intensity and label scheme is solved.

It is understood that, in the embodiment of the present application, the second electronic device 200 and the third electronic device 300 may include, but are not limited to: intelligent household devices such as smart television, intelligent audio amplifier, intelligent wrist-watch, intelligent bracelet, intelligent refrigerator, intelligent air conditioner.

It is understood that, in the embodiment of the present application, the first electronic device 100 may include, but is not limited to: a cell phone, tablet, wearable device, portable game, portable music player, reader device, or other electronic device having an antenna array. In the following description, for simplicity of explanation, the first electronic device 100 is taken as a mobile phone, and the user control command is taken as a voice command as an example to explain the technical solution of the present application.

Based on the structure shown in fig. 5, the technical solution of the present application will be described in detail with reference to fig. 6 and a specific scenario. In the embodiment shown in fig. 6, the second electronic device 200 is exemplified by a speaker, and the third electronic device 300 is exemplified by a television. Furthermore, in this embodiment, in order to reduce the overall power consumption, the wireless scanning and wireless broadcasting of the handset 100 are handled by the co-processor 111, while the processor 110 is in a sleep state.

As shown in fig. 6, the solution of the directional control electronic device of the present application includes:

in step S601, the mobile phone 100 initiates a wireless scan. The wireless scanning is used for receiving a wireless broadcast signal sent by an external electronic device, and before the mobile phone 100 initiates the wireless scanning, the mobile phone 100 does not receive the wireless broadcast signal sent by the electronic device, such as the sound box 200 or the television 300.

In some embodiments of the present application, the mobile phone 100 may perform wireless scanning through the bluetooth communication module or the bluetooth low energy communication module to receive a bluetooth broadcast signal transmitted by an external electronic device. Here, the bluetooth communication module or the bluetooth low energy communication module may be used for communication via bluetooth as well as Bluetooth Low Energy (BLE). The term "bluetooth" has its full scope of ordinary meaning and includes at least any of the various implementations of the existing bluetooth standard, including Bluetooth Low Energy (BLE), including future implementations of the bluetooth standard, and the like. For example, a bluetooth connection comprises a bluetooth connection based on the bluetooth protocol 4.x, e.g. 4.2, or comprises a bluetooth connection based on the bluetooth protocol 5.x, e.g. 5.0. In addition, the bluetooth connection may also include Bluetooth Low Energy (BLE). BLE aims at significantly reducing power consumption and cost compared to classical bluetooth, while maintaining a similar communication range as classical bluetooth. In some embodiments the bluetooth communication module may additionally be incorporated in other communication modules, such as modules for Wi-Fi or WLAN (e.g., 802.11) communication, and the like. For simplicity, only the application of BLE technology in various embodiments is described below, it being understood that classic bluetooth, Wi-Fi, and other short-range communication technologies may be applied in various embodiments of the present application.

In some embodiments of the present application, the coprocessor 111 in the mobile phone 100 sends a bluetooth scanning instruction to the bluetooth communication module or the bluetooth low energy communication module, so that the bluetooth communication module or the bluetooth low energy communication module completes receiving a bluetooth broadcast signal sent by the smart device. When the processor 110 of the handset 100 is in a sleep state, the power consumption of the handset 100 can be reduced to a large extent by using the co-processor 111 to complete bluetooth scanning.

Here, the coprocessor 111 includes a bluetooth protocol stack and a bluetooth driver. The bluetooth protocol stack and the bluetooth driver in the coprocessor 111 are formed by migrating at least part of functions of the bluetooth protocol stack and the bluetooth driver operated at the processor 110 side to the coprocessor 111 side in a code migration manner, such as bluetooth broadcasting (ADV), bluetooth Scanning (Scanning), and the like. The bluetooth protocol stack in the coprocessor 111 may execute the respective bluetooth protocol for broadcasting and scanning, and the bluetooth driver may include part or all of a driver that drives the bluetooth communication module.

In some embodiments, the bluetooth protocol stack in the co-processor 111 is provided with the same security protocol as the bluetooth protocol stack of the processor 110, so that the data security of bluetooth communication via the co-processor 111 can be protected by the bluetooth security protocol.

In addition, the bluetooth communication module and the coprocessor 111 perform data transmission via an Inter Integrated Circuit (I2C) or a modified Inter Integrated Circuit (I3C). The I2C interface is a bidirectional synchronous Serial bus including a Serial Data Line (SDA) and a Serial Clock Line (SCL). I3C is an improvement over I2C, is compatible with the I2C protocol, and combines the advantages of I2C (two-wire, simple) and SPI (low power consumption, high speed).

In steps S602 and S603, sound box 200 and television 300 respectively transmit wireless broadcast signals.

For example, the sound box 200 and the television 300 periodically transmit the radio broadcast signal to the outside, and the transmission time interval may be set according to the user's needs or factory settings, for example, 5 seconds or 10 seconds.

In some embodiments of the application, the sound box 200 and the television 300 respectively send a bluetooth broadcast signal to the outside, the bluetooth broadcast signal sent by the sound box 200 includes an equipment identifier of the sound box 200, the bluetooth broadcast signal sent by the television 300 includes an equipment identifier of the television 300, the equipment identifier is used for uniquely identifying a corresponding electronic equipment, the equipment identifier may be, for example, a hardware identification code corresponding to the electronic equipment, or a network address corresponding to the electronic equipment, and the mobile phone 100 receives the bluetooth broadcast signal sent by the sound box 200 and the television 300 through a bluetooth communication module or a bluetooth low-power communication module, and uploads the bluetooth broadcast signal to the coprocessor 111.

Fig. 7 shows a scenario in which the electronic device transmits a bluetooth broadcast signal to the cellular phone 100. As shown in fig. 7, the second electronic device is a television 300, the third electronic device is a sound box 200, the device identifier is a wave arrival angle identifier, the television 300 and the sound box 200 respectively control the bluetooth communication module or the bluetooth low energy communication module to send bluetooth broadcast signals through the processor, the bluetooth broadcast signals respectively include the device identifiers AOA ID1 and AOA ID2, and the mobile phone 100 receives the bluetooth broadcast signals through the bluetooth communication module or the bluetooth low energy communication module that performs bluetooth scanning and transmits the bluetooth broadcast signals to the coprocessor 111.

It can be understood that the bluetooth broadcast signals transmitted by the sound box 200 and the television 300 may be broadcast data transmitted by using a normal bluetooth protocol, or broadcast data transmitted by using a bluetooth low energy protocol, and the embodiment of the present application does not specifically limit which bluetooth protocol is specifically used.

In step S604, the mobile phone 100 determines the angle of arrival information corresponding to each electronic device according to the wireless broadcast signal received from each electronic device. The information on the angle of arrival indicates information on the angle of arrival of a radio broadcast signal transmitted from the electronic device at the mobile phone 100, for example, the antenna pitch d, the phase difference ψ when the radio broadcast signal reaches different antennas, the wavelength λ of the radio broadcast signal, and the like. The distance difference of the wireless broadcast signal to different antennas of the mobile phone 100 can be calculated through the arrival angle information, and the device angle between the mobile phone 100 and the electronic device can be obtained through the distance difference.

Here, the mobile phone 100 receives the radio broadcast signals transmitted from the sound box 200 and the television 300, respectively, and determines the information on the angle of arrival of the radio broadcast signal transmitted from the sound box 200 and the information on the angle of arrival of the radio broadcast signal transmitted from the television 300 of the sound box 200, based on the arrival of the radio broadcast signals at the antenna array of the mobile phone 100.

It should be understood that only two electronic devices are shown in fig. 6, but the number of electronic devices in fig. 6 is not limited to the number of electronic devices in the embodiment of the present application, and the mobile phone 100 may receive the wireless broadcast signals of two or more electronic devices, and the embodiment of the present application does not limit the number of electronic devices that transmit the wireless broadcast signals.

In some embodiments of the present application, the mobile phone 100 receives a bluetooth broadcast signal transmitted by the speaker 200 or the television 300 through a bluetooth communication module or a bluetooth low energy communication module, and determines corresponding information of the angle of arrival according to the received bluetooth broadcast signal. In some embodiments, the angle of arrival information includes, but is not limited to, the following: the antenna spacing d, the phase difference psi when the Bluetooth broadcast signal arrives at different antennas, and the wavelength lambda of the Bluetooth signal.

Here, the antenna pitch refers to a pitch between different antennas in the antenna array of the handset 100. The phase difference psi refers to the difference in phase between the bluetooth signals received by different antennas in the antenna array. Fig. 8 shows a scenario in which a bluetooth signal transmitted by a transmitting device is received by different antennas in an antenna array of a receiving device, as shown in fig. 8, the transmitting device transmits a bluetooth broadcast signal through the antennas, and the receiving device receives the bluetooth broadcast signal through the antenna array, and a distance d exists between different antennas in the antenna array, so that distances through which the bluetooth broadcast signal transmitted by the antennas of the transmitting device propagates to different antennas of the receiving device in the form of electromagnetic waves are different, and therefore phases of the bluetooth signal received by different antennas in the antenna array of the receiving device are also different, and a phase difference ψ exists between the phases.

Further, fig. 9(a) shows a correspondence of a wavelength and a phase of a bluetooth signal, λ being the wavelength of the bluetooth signal, and a signal of one wavelength corresponding to a phase of 0 to 2 π. As described above, since the transmitting device is not at the same distance from different antennas, the phases of the bluetooth signals received by different antennas are different. For example, fig. 9(b) shows a waveform diagram of the bluetooth signal received by the antenna 1 and the antenna 2 at a distance d, and as shown in fig. 9(b), the phase of the bluetooth signal received by the antenna 1 is ψ ₁ Phase psi of bluetooth signal received by antenna 2 ₂ The phase difference between the two antennas is psi ₁ -ψ ₂ According to the corresponding relationship between the wavelength and the phase, the distance difference s between the antenna 1 and the antenna 2 receiving the bluetooth signal is ψ λ/2 pi. Then according to the triangleThe functional relationship can obtain the device angle theta (arccos (psi lambda/2 pi d)).

In some embodiments of the present application, the bluetooth communication module or the bluetooth low energy communication module may determine the phase difference ψ and the bluetooth signal wavelength λ by receiving bluetooth data sent by the sending device, send the phase difference ψ and the bluetooth signal wavelength λ together with a known antenna spacing d to the coprocessor 111 in the mobile phone 100, and perform subsequent processing by the coprocessor 111, thereby avoiding that these information is sent to the processor 110 to wake up the processor 110, and reducing the overall power consumption of the mobile phone 100.

In step S605, the mobile phone 100 determines the device angle between the mobile phone 100 and the speaker 200 or the television 300 according to the information of the angle of arrival.

Here, after the wireless broadcast signal transmitted by the speaker 200 reaches the mobile phone 100, the mobile phone 100 obtains the information of the angle of arrival corresponding to the speaker 200, and after the wireless broadcast signal transmitted by the television 300 reaches the mobile phone 100, the mobile phone 100 obtains the information of the angle of arrival corresponding to the television 300, and the mobile phone 100 uses the coprocessor 111 to calculate the information of the angle of arrival corresponding to the speaker 200 and the information of the angle of arrival corresponding to the television 300, respectively, so as to obtain the device angle between the mobile phone 100 and the speaker 200 and the device angle between the mobile phone 100 and the television 300.

With continued reference to fig. 8, from the distance difference s and the antenna spacing d, we can obtain cos (θ) ═ s/d ψ λ/2 π d, θ is the device angle of the receiving device relative to the transmitting device, so we can derive the formula for θ as follows:

θ＝arccos(ψλ/2πd)。

here, the device angle of the receiving device with respect to the transmitting device is an azimuth angle, that is, an angle between an antenna array plane of the receiving device and the received signal, and the antenna array plane refers to a plane formed by the tips of a plurality of antennas in the antenna array.

Fig. 10 shows a scenario in which the handset 100 calculates the device angle from the received bluetooth broadcast signal, respectively. As shown in fig. 10, the third electronic device is a television 300, the second electronic device is a sound box 200, the television 300 and the sound box 200 broadcast the bluetooth signal periodically, the bluetooth signal sent by the television 300 includes the device identifier AOA ID1 of the television 300, and the sound box 200 contains the AOA ID2 of the speaker 200, and the handset 100 has an antenna array. The mobile phone 100 receives the bluetooth broadcast signal from the television 300 or the sound box 200 under the condition that the processor 110 is in sleep, transmits the information of the angle of arrival obtained when the bluetooth broadcast signal is received to the coprocessor 111, and respectively calculates the device angle theta between the mobile phone 100 and the television 300 by the coprocessor 111 ₁ And the device angle theta between the handset 100 and the speaker 200 ₂ 。

In step S606, the mobile phone 100 determines the device identifier of the electronic device pointed by the mobile phone 100 according to the device angle. Here, the electronic device pointed by the mobile phone 100 specifically refers to the electronic device pointed by the antenna array of the mobile phone 100. In addition, the mobile phone 100 obtains corresponding angle of arrival information according to the device angle, and then obtains the device identifier included in the corresponding wireless broadcast signal according to the angle of arrival information.

Fig. 11 shows a scenario in which the user points the mobile phone 100 to the electronic device, as shown in fig. 11, the user points the mobile phone 100 to the speaker 200, the mobile phone 100 receives the bluetooth broadcast signals sent by the television 300 and the speaker 200 and determines corresponding information of the angle of arrival under the condition that the processor 110 is asleep, and the co-processor 111 calculates the device angle θ between the mobile phone 100 and the television 300 according to the corresponding information of the angle of arrival ₁ And the device angle theta between the handset 100 and the speaker 200 ₂ ，θ ₂ Is approximately 90.

In some embodiments of the present application, the coprocessor 111 in the mobile phone 100 checks whether the calculated device angle satisfies a preset condition, and determines the electronic device corresponding to the device angle as the electronic device pointed by the mobile phone 100 when the device angle satisfies the preset condition, where the device identifier of the electronic device pointed by the mobile phone 100 is the device identifier of the electronic device.

Here, the preset conditions may include, but are not limited to, the following: a fixed value, a value range, or a value range centered on a fixed value, etc. For example, the preset condition may be a fixed angle value such as 90 °, a value range such as [80 °, 100 °, or a value range of ± 15 ° centered at 90 °.

With continued reference to figure 11 of the drawings,setting the preset condition that the angle of the equipment is at [80 degrees ], 100 degrees]Due to the device angle theta between the mobile phone 100 and the sound box 200 ₂ Approximately 90 °, therefore, when the preset condition is satisfied, the mobile phone 100 uses the device identifier AOA ID2 of the sound box 200 as the device identifier of the electronic device to which the mobile phone 100 points; device angle theta between handset 100 and television 300 ₁ The preset condition is clearly not met and therefore the handset 100 does not have the device identification AOA ID1 of the television 300 as the device identification of the electronic device to which the handset 100 is pointing.

In some embodiments of the present application, device angles between two or more electronic devices and the mobile phone 100 may satisfy a preset condition, in which case, the mobile phone 100 may use device identifiers of the two or more electronic devices as candidates of device identifiers of the electronic device pointed by the mobile phone 100, and then determine a device identifier from the candidate device identifiers. For example, the mobile phone 100 may determine the device identifier according to the size of the device angle, and determine the device identifier of the electronic device corresponding to the largest device angle as the device identifier of the electronic device pointed by the mobile phone 100, where the largest device angle between the mobile phone 100 and the electronic device indicates that the distance between the pointed direction of the mobile phone 100 and the electronic device is the smallest.

Step S607, the coprocessor 111 in the mobile phone 100 detects a user operation, compares the user operation with a preset user trigger operation, and continues to detect the user operation if the user operation is inconsistent with the preset user trigger operation; if the user operation is consistent with the preset user trigger operation, step S608 is executed.

In some embodiments of the present application, the triggering operation of the user is preset, and may include but is not limited to: sensor trigger operations, screen touch operations, etc. The sensor triggering operation is an operation related to triggering a sensor on the mobile phone 100, such as a process of re-holding the bezel of the mobile phone 100, shaking the mobile phone 100, and the like. The screen touch operation is a plurality of touch operations performed on the screen of the mobile phone 100, for example, a finger clicks a preset screen area, a finger slides on the preset screen area, a plurality of fingers slide on the screen, and the like.

In step S608, the mobile phone 100 transmits a wireless broadcast signal including a device identifier, where the device identifier is a device identifier of an electronic device pointed by the mobile phone 100, and both the speaker 200 and the television 300 can receive the wireless broadcast signal including the device identifier because the mobile phone 100 transmits broadcast data.

With continued reference to fig. 11, in this scenario, the device ID of the electronic device pointed to by handset 100 is the device ID AOA ID2 of sound box 200, so that the wireless broadcast signal transmitted by handset 100 includes the device ID AOA ID2 of sound box 200.

In some embodiments of the present application, the coprocessor 111 of the mobile phone 100 sends the bluetooth broadcast signal through the bluetooth communication module or the bluetooth low energy communication module. The coprocessor 111 sends a bluetooth broadcast instruction to the bluetooth communication module or the bluetooth low energy communication module, and transmits the device identifier of the smart device to which the mobile phone 100 points, and the bluetooth communication module or the bluetooth low energy communication module generates a bluetooth broadcast signal according to the received bluetooth broadcast instruction and the device identifier of the electronic device to which the mobile phone 100 points, and sends the bluetooth broadcast signal.

In some embodiments of the present application, the bluetooth broadcast signal transmitted by the handset 100 includes a bluetooth preamble or a bluetooth low energy preamble in addition to the device identifier of the electronic device pointed to by the handset 100.

Fig. 12 shows the structure of the bluetooth broadcast signal transmitted by the cellular phone 100. As shown in fig. 12, the bluetooth broadcast signal includes a preamble and a device identifier, the preamble is a field necessary for the bluetooth broadcast, and a filter in the bluetooth scan can filter out the bluetooth broadcast signal that is not of interest through the preamble. The device identifier designates a device identifier of an electronic device pointed by the mobile phone 100, and the electronic device can resolve the device identifier after receiving the bluetooth broadcast signal.

Fig. 13 shows a scenario in which the mobile phone 100 transmits a bluetooth broadcast signal to an electronic device. As shown in fig. 13, the coprocessor 111 of the mobile phone 100 sends a bluetooth broadcast signal through the bluetooth communication module, where the bluetooth broadcast signal includes the device identifier AOA ID1, and the television 300 and the speaker 200 receive the bluetooth broadcast signal through the bluetooth communication module and upload the bluetooth broadcast signal to various processors.

Step S609 and step S610, the sound box 200 and the television 300 respectively check the device identifier in the received wireless broadcast signal, that is, compare the device identifier from the wireless broadcast signal with the device identifier of itself, if they are consistent, the electronic device with the consistent comparison result responds to the user instruction, that is, step S611 is executed; if not, the electronic device with inconsistent comparison result closes the response to the user instruction, i.e. step S612 is executed.

In step S611, the sound box 200 enables its own response system to the user instruction, so that the user instruction can be responded to.

In step S612, the television 300 turns off its response system to the user command, and avoids responding to the user command.

Fig. 14(a) and 14(b) show a scenario in which the user transmits the device identification of the electronic device to which the mobile phone 100 is pointing by a trigger operation. As shown in fig. 14(a), the third electronic device is a television 300, the second electronic device is a smart speaker, the electronic device pointed by the mobile phone 100 is a speaker 200, the device identifier of the speaker 200 is AOA ID2, and the user performs a trigger operation to make the mobile phone 100 send a bluetooth broadcast signal containing the device identifier AOA ID2 when the processor 110 is in sleep coprocessor operation.

The tv 300 receives the bluetooth broadcast signal and parses out the device ID AOA 2 therein, and then performs step S610 to compare the device ID AOA 2 with its own device ID, and since the device ID of the tv 300 is AOA ID1, the two are not consistent, so that step S612 is performed to shut down the response of the tv 300 to the user command, such as the voice system. And the sound box 200 receives the bluetooth broadcast signal and analyzes the device identifier AOA ID2 therein, execute step S609 to compare the device identifier AOA ID2 with its own device identifier, and since the device identifier of the sound box 200 is AOA ID2, the two are consistent, execute step S611 to respond to the user 'S instruction, for example, to enable the voice system of the sound box 200, that is, to enable the voice system of the sound box 200 if the voice system of the sound box 200 is in the off state, the voice system of the sound box 200 is turned on, and to keep on if the voice system of the sound box 200 is in the on state, so that the voice response can be performed to the user' S voice instruction. Subsequently, the user issues an instruction such as a voice instruction "art, how today? "and then as shown in fig. 14(b), the sound box 200 makes a voice response to the voice command issued by the user" today weather XX, temperature XX ".

In some embodiments of the present application, the response to the user instruction is turned off for a certain time limit, and the response to the user instruction by the electronic device is turned back on after the turn-off time exceeds a preset time limit threshold. For example, in the above example, the voice response system of television 300 may be turned on again after being turned off for a preset time period threshold, such as 3 minutes.

The instruction sent by the user can correspond to a preset human body gesture, a preset gesture or a preset human face expression and the like. After determining the instruction sent by the user, the electronic device responds according to the instruction of the user, and the responding mode is, for example, voice response.

Fig. 15(a) and 15(b) show the interaction flow of the processor 110 controlling the orientation control function of the coprocessor 111 to turn on or off in the mobile phone 100. As shown in fig. 15(a), the processor 110 sends a directional control function start instruction to the coprocessor 111, and the coprocessor 111 enables the directional control function after receiving the start instruction, so that the coprocessor 111 can perform related processing of directional control. The electronic device 200 periodically sends a bluetooth broadcast signal, the coprocessor 111 receives the information of the angle of arrival related to the bluetooth broadcast signal uploaded by the bluetooth communication module or the bluetooth low energy communication module, performs a subsequent directional control process such as calculation of a device angle, and sends the bluetooth broadcast signal after detecting a user trigger operation. As shown in fig. 15(b), in the mobile phone 100, the processor 110 sends a command to the coprocessor 111 to turn off the directional control function, and the coprocessor 111 turns off the directional control function after receiving the command to turn off, so that the coprocessor 111 does not process the information of the angle of arrival of the bluetooth broadcast signal even when receiving the bluetooth broadcast signal sent by the electronic device 200.

The sending module sends the device identification from the processing module to the communication module, so that the communication module sends the Bluetooth data containing the device identification through the Bluetooth communication module in a Bluetooth broadcast mode.

In some embodiments of the present application, the voice system of the handset 100 may be turned off in a directional control scenario, thereby avoiding possible interference with the user's voice control instructions. Fig. 17 shows an interaction flow of turning off the voice system in the coprocessor 111 in the mobile phone 100. As shown in fig. 17, the trigger operation detection module detects a user operation, and after detecting that the user operation is a trigger operation, sends a notification of the detection of the user trigger operation to the enabling module. And after receiving the notification, the enabling module sends a closing instruction to the voice system.
