Background
With the continuous popularization of full-scene intelligent equipment, the life of a user becomes more convenient. However, when a user is in an environment with multiple full-scene smart devices, there is no way to accurately prepare to determine on which full-scene smart device the user's attention is focused. This problem is critical for certain scenarios, such as, where multiple full-scene smart devices are awakened by a voice assistant together, the best experience is to accurately awaken the voice assistant on the full-scene smart device that the user's attention is focused on when the user calls the voice assistant.
Disclosure of Invention
In view of the above problems in the prior art, an object of the present application is to provide a method and an apparatus for determining a device to be noticed, and a head-mounted electronic device, which can determine a device to which a user is attentive and improve user experience when a plurality of smart devices are woken up together by a voice of the user.
In a first aspect of the embodiments of the present application, a method for determining an attention device is provided, where the method is applied to a head-mounted electronic device, and the head-mounted electronic device includes: a central Li-Fi receiver having a receiving end oriented in a direction that is coincident with a direction in which a face of a user wearing the head-mounted electronic device faces and side Li-Fi receivers positioned on either side of the central Li-Fi receiver, the receiving ends of the side Li-Fi receivers oriented at a first angle relative to the orientation of the receiving end of the central Li-Fi receiver, the method comprising: receiving, by the central Li-Fi receiver and the lateral Li-Fi receivers, li-Fi optical signals transmitted by devices; when the light power of the device's Li-Fi light signal received by the central Li-Fi receiver is greater than the light power of the device's Li-Fi light signal received by the lateral Li-Fi receiver, the device is an attended device.
Through the arrangement, when the face of the user faces a certain device, the attention of the user is concentrated on the device with high probability, and at the moment, under the condition that the orientation of the receiving end is consistent, the light power of the Li-Fi light signal received by the central Li-Fi receiver is larger than that of the Li-Fi light signal received by the lateral Li-Fi receiver, so that the noticed device can be determined.
In one possible implementation manner, the method further includes: when the noticed device is a plurality of devices, acquiring the distance between the central Li-Fi receiver and the noticed device; and determining the device with the maximum attention degree as the attention-paid device according to the relation between the distance between the central Li-Fi receiver and the attention-paid device and the attention degree.
Through the arrangement, when the number of the noticed devices is multiple, the only noticed device can be determined according to the relation between the distance between the central Li-Fi receiver and the noticed devices and the attention degree, so that multiple rounds of voice interaction between a user and the devices are avoided, and the user experience is improved.
In one possible implementation, the obtaining of the distance includes: determining a distance between the attended device and the central Li-Fi receiver from the optical power of the attended device received by the central Li-Fi receiver, the emission power of the Li-Fi optical signal of the attended device.

With the above arrangement, since the distance from the device is generally relatively fixed when the user uses the device, for example, the distances from the user to the television, the mobile phone, and the air conditioner are generally relatively fixed and different when the user uses the television, the mobile phone, and the air conditioner, when the number of devices to be noticed is plural, the only device to be noticed, in which the user focuses attention, can be specified based on the distance between the user and the device to be noticed.
In one possible implementation, the relationship between the distance and the attention level between the central Li-Fi receiver and the device is established by: periodically collecting a distance between the central Li-Fi receiver and a device and a use frequency of the device at the distance when the head-mounted electronic device is used; establishing a relationship between the distance and the degree of attention between the central Li-Fi receiver and the device according to the distance and the frequency of use.
Through the setting, the times of using each device by a user at different distances can be acquired for many times within a long period of time. For example, the distance between the user and each device and the use condition of each device at the current distance are collected every 2 minutes in the first 6 months when the user uses the head-mounted electronic device, and the number of times that the user uses each device at different distances is further obtained. Since the distance from each device is relatively fixed and different when the user uses different devices, the more times the user uses a device at a certain distance, the more likely the user is to concentrate on the device at the certain distance, and thus the relationship between the distance and the attention degree between the user and the device is obtained, so as to prepare for determining the device in which the user is concentrated.

The third embodiment is as follows: method for determining noticed device
Fig. 4 shows a flowchart of a method for determining an attention device according to an embodiment of the present application. As shown in fig. 4, the method of determining the noticed device may include the steps of:
step S1: the user wears the head-mounted electronic device.
In some embodiments, the head-mounted electronic device may be smart glasses, smart headphones, or other devices or smart devices, which is not limited in this application.
Step S2: the user issues a voice instruction.
In some embodiments, as shown in FIG. 1, a user says in a smart device environment: and turning on the television. In fig. 1, the smart device environment in which the user is located may include: the intelligent floor sweeping robot comprises an intelligent floor sweeping robot 1, an intelligent air conditioner 2, an intelligent sound box 3, an intelligent television 4 and an intelligent mobile phone 5, wherein the intelligent equipment sends Li-Fi optical signals. Of course, the method for determining the noticed device provided in the embodiments of the present application may also be applied to other non-intelligent devices, and the "device" in this document and the drawings refers to an intelligent device and other non-intelligent devices.
And step S3: the Li-Fi transmitters of the plurality of smart devices transmit Li-Fi optical signals.
After a user sends a voice instruction, voice assistants of the intelligent devices receive the voice instruction sent by the user, and the control unit controls the Li-Fi emitter arranged on the intelligent devices to emit Li-Fi optical signals according to the voice instruction of the user.
And step S4: the central Li-Fi receiver, the first side Li-Fi receiver and the second side Li-Fi receiver receive Li-Fi optical signals sent by the Li-Fi transmitters of the plurality of intelligent devices.
In some embodiments, the direction in which the receiving end of the central Li-Fi receiver faces coincides with the direction in which the face of a user wearing the head-mounted electronic device faces. The orientation of the receiving ends of the first and second side Li-Fi receivers is at an angle (first angle) relative to the orientation of the receiving end of the central Li-Fi receiver, which may be the same or different, and which may range from ± 90 °. The number of the central Li-Fi receiver, the first side Li-Fi receiver and the second side Li-Fi receiver can be one or more, and the first side Li-Fi receiver and the second side Li-Fi receiver are respectively arranged on two sides of the central Li-Fi receiver.
Step S5: and the processor determines the trusted intelligent equipment according to the identity ID information of the intelligent equipment contained in the Li-Fi optical signal.
In some embodiments, the Li-Fi optical signal transmitted by the Li-Fi transmitter on the smart device may include Identity ID (Identity profile) information of the smart device, for example, the Li-Fi optical signal may include information of a user account to which the smart device belongs. The processor may match user account information to which the smart device belongs with user account information to which the head-mounted electronic device belongs, and when the two pieces of user account information are consistent, the smart device corresponding to the Li-Fi optical signal is a trusted smart device.
Step S6: the processor judges whether the light power of the Li-Fi light signals sent by the intelligent equipment and received by the central Li-Fi receiver is maximum or not.
When the face of a user faces a certain device, the attention of the user is concentrated on the device with high probability, and under the condition that the receiving end of the central Li-Fi receiver forms a certain angle relative to the receiving end of the side Li-Fi receiver, and the facing direction of the receiving end of the central Li-Fi receiver is consistent with the face direction of the user wearing the head-mounted electronic device, the light power of the Li-Fi light signal received by the central Li-Fi receiver is larger than that of the Li-Fi light signal received by the side Li-Fi receiver, so that the noticed device can be determined.
In some embodiments, for any smart device, when the Li-Fi optical power received by the central Li-Fi receiver is greater than the Li-Fi optical power received by any one of the Li-Fi receivers, the angle between the axis of the receiving end of the central Li-Fi receiver and the incident angle of the Li-Fi optical signal received by the central Li-Fi receiver may be regarded as 0 °.
When the light power of the Li-Fi light signal sent by the smart device received by the central Li-Fi receiver is the maximum, executing step S7: the smart device is determined to be the noticed smart device.
When the light power of the Li-Fi optical signal received by the central Li-Fi receiver and sent by the smart device is not the maximum, that is, the light power of the Li-Fi optical signal received by the central Li-Fi receiver and sent by the smart device is smaller than the light power received by the side Li-Fi receiver, step S61 is executed: the processor treats the smart device as a non-noticed smart device.
Step S8: the processor determines whether the number of noticed smart devices is 0.
When the number of noticed smart devices is 0, step S81 is performed: the processor determines that the smart device is unattended.
When the number of noticed smart devices is not 0, step S9 is performed: the processor determines whether the number of noticed smart devices is 1.
When the number of noticed smart devices is 1, step S91 is performed: the processor determines that the device is an attended smart device.
When the number of noticed smart devices is not 1, step S10 is performed: the distance between each noticed smart device and the central Li-Fi receiver is calculated.
Since the distance from the device is usually relatively fixed when the user uses the device, for example, when the user uses a television, a mobile phone and an air conditioner, the distance from the user to the television, the distance from the user to the mobile phone and the distance from the user to the air conditioner are usually relatively fixed and different, when the user uses the television, the distance from the user to the mobile phone is usually 2 meters to 3 meters, when the user uses the mobile phone, the distance from the user to the mobile phone is usually 0.3 meters to 0.8 meters, when the user enters a room, the distance from the user to the air conditioner is usually 2 meters to 10 meters, when the number of the devices to be noticed is multiple, the only device to be noticed can be determined based on the distance between the user and the device to be noticed.
In some embodiments, the distance between the user attention device and the central Li-Fi receiver may be calculated by:
according to the formula (1) P LOS =P t ×H (0) Calculate H (0) Wherein P is LOS The optical power of the Li-Fi optical signal of the intelligent device received by the central Li-Fi receiver; p t The light power of a Li-Fi light signal emitted by a Li-Fi emitter of the intelligent device; h (0) Is the dc gain of the channel.
According to formula (2)
Figure BDA0003003913660000081
A distance between the smart device and the central Li-Fi receiver is determined.
Wherein H (0) Is the dc gain of the channel; m is Lambert order, m = -ln2/ln (cos φ) 1/2 ),φ 1/2 An LED lamp half-power angle for a Li-Fi emitter; a is the acceptance area of the photodiode of the receiver; psi is the included angle between the axis of the receiving end of the receiver and the incident light; t is s (ψ) is the optical filter gain of the receiver; g (psi) is the optical lens convergence signal gain of the receiver; psi c Is the half-angle width of the field of view; phi is an included angle between a vertical axis of an LED lamp of the Li-Fi emitter and emitted light; r is the distance between the LED lamp of the Li-Fi transmitter and the central Li-Fi receiver (distance between the smart device and the central Li-Fi receiver), which can represent the distance between the user and the smart device.
In step S6, when the central Li-Fi receiver receives a light power greater than the light power received by the first and second Li-Fi receivers (all the side Li-Fi receivers), the angle between the axis of the receiving end of the central Li-Fi receiver and the incident angle of the light received by it may be regarded as 0 °. Therefore, in the formula (2), the distances r between the LED lamp of the Li-Fi transmitter and the central Li-Fi receiver, i.e. the distance between the smart devices noticed by the user of the central Li-Fi receiver, can be calculated, except that the distances between the LED lamp of the Li-Fi transmitter and the central Li-Fi receiver are unknown.
Step S11: the attention level of each attention device to be noticed by the user is determined from the relationship of the distance and the attention level between the user (central Li-Fi receiver) and each attention device.
Since the distance from each device is relatively fixed and different when the user uses different devices, the more times the user uses a device at a certain distance, the more likely it is that the user's attention at that distance is focused on the device.
In some embodiments, the association curve of distance and attention level between each device and the central Li-Fi receiver may be obtained by:
step S111: when the user wears the head-mounted electronic device, the distances between the central Li-Fi receiver and the respective smart devices are collected once every predetermined time (periodic collection).
For example, the distance between the user and each device and the use condition of each device at the current distance may be collected every 2 minutes in the first 6 months when the user uses the head-mounted electronic device, so as to obtain the number of times that the user uses each device at different distances.
In some embodiments, the predetermined time may be any time period, for example, 1 minute to 20 minutes, which is not limited in this application. When wearing the head-mounted electronic equipment, the user can move freely in the intelligent equipment environment. Taking the scenario shown in fig. 1 as an example, the processor may respectively calculate distances between the central Li-Fi receiver and the intelligent floor sweeping robot 1, the intelligent air conditioner 2, the intelligent sound box 3, the intelligent television 4, and the smart phone 5 according to Li-Fi optical signals acquired by the central Li-Fi receiver or the side Li-Fi receivers disposed on the head-mounted electronic device. For example, the distances between the central Li-Fi receiver and the intelligent floor sweeping robot 1, the intelligent air conditioner 2, the intelligent sound box 3, the intelligent television 4 and the intelligent mobile phone 5 are 2.1 meters, 2.4 meters, 2.2 meters, 2.1 meters and 0.4 meters, respectively.
Step S112: and determining the situation that the user uses the intelligent device under different distances.
In some embodiments, at the first time, when the user is watching tv and playing a mobile phone, the situation of the user using the device is as follows: a user uses a smart television and a smart phone, and does not use an intelligent floor sweeping robot, an intelligent air conditioner and an intelligent sound box; when a user uses the intelligent television, the distance between the central Li-Fi receiver and the intelligent television is 2.1 meters; when the user uses the smart phone, the distance between the central Li-Fi receiver and the smart phone is 0.4 m.
Step S113: and determining the use frequency of the equipment at different distances according to the acquired distance between the central Li-Fi receiver and the equipment for N times.
In some embodiments, distances between the central Li-Fi receiver and various smart devices may be collected every 2 minutes when the user wears the head-mounted electronic device in the first 3 months when the user uses the head-mounted electronic device provided in the embodiments of the present application, and the number of times collected in the three months and N are taken as the total collection times. For example, in the first 3 months, the head-mounted electronic device acquires the distance between the central Li-Fi receiver and each smart device for 13500 times, wherein the distance between the central Li-Fi receiver and the smart television is 0.2-12 m, the distance between the central Li-Fi receiver and the smart air conditioner is 0.5-10 m, the distance between the central Li-Fi receiver and the smart phone is 0.1-2 m, the distance between the central Li-Fi receiver and the smart sound box is 0.3-9 m, and the distance between the central Li-Fi receiver and the smart sweeping robot is 0.2-15 m. The number of times that a user uses the intelligent television between 0.1 m and 2 m from the intelligent television is 300, the number of times that the user uses the intelligent air conditioner is 15, the number of times that the user uses the intelligent mobile phone is 9500, the number of times that the user uses the intelligent floor sweeping robot is 30, and the number of times that the user uses the intelligent sound box is 100; the number of times that a user uses the intelligent television between 2 meters and 3 meters away from the intelligent television is 7200, the number of times that the user uses the intelligent air conditioner is 70, the number of times that the user uses the intelligent mobile phone is 500, the number of times that the user uses the intelligent floor sweeping robot is 40, and the number of times that the user uses the intelligent sound box is 680; the number of times that a user uses the intelligent television between 3 meters and 12 meters from the intelligent television is 505, the number of times that the user uses the intelligent air conditioner is 115, the number of times that the user uses the intelligent mobile phone is 12, the number of times that the user uses the intelligent floor sweeping robot is 20, and the number of times that the user uses the intelligent sound box is 115.
Step S114: and obtaining a correlation curve of the distance and the attention degree according to the times of using the intelligent equipment by the user at different distances.
In some embodiments, the more times a user uses a smart device at a distance or distance range indicates that the more frequently the user uses the smart device at the distance or distance range, the more likely the user is to concentrate on the smart device at the distance or distance range, i.e., the number of times the user uses the smart home device during the period of time (e.g., 3 months in step S113) can represent the attention level of the user.
In some embodiments, the attention curves of the user using the smart tv, the smart phone, the smart speaker, the smart air conditioner, and the smart sweeping robot in the range of 0-15 m are shown in fig. 5. Of course, the distance and attention degree correlation table may also be drawn according to the number of times that the user uses the smart device at different distances, which is not limited in the present application as long as the correspondence between the number of times that the user uses the smart device and the distance between the central Li-Fi receiver and the smart device can be reflected.
Step S12: and taking the intelligent device with the greatest attention degree as the user attention device.
In some embodiments, as shown in fig. 1, the distances between the user (central Li-Fi receiver) and the smart devices are known in step S111, and the attention degrees of the user paying attention to the smart devices are determined according to the correlation curves of the distances and the attention degrees shown in fig. 5, where the device paying attention to the user is the device paying attention to the device with the greatest attention degree.
