Description

Equipment interaction method and device

Technical Field

The present application relates to the Field of Near Field Communication (NFC), and in particular, to a device interaction method and apparatus.

Background

Currently, a user generally owns a plurality of terminal devices with different forms, such as a mobile phone, a tablet, a smart speaker, and a smart desk lamp. With the continuous development of the full-scene technology, the device interaction among a plurality of terminal devices is more and more.

There are ways to implement device interaction based on NFC in the prior art. Specifically, after the NFC induction area of the mobile phone is contacted with the NFC label on the notebook computer, the mobile phone is automatically paired to establish communication connection, so that the mobile phone and the notebook computer are connected in a collision mode.

In the existing equipment interaction mode, after the NFC induction area is contacted with the NFC label, a predefined interaction task is automatically executed, so that the user operation path can be shortened to a certain extent, and the user operation is simplified. However, only one kind of interaction task is predefined, and other interactions between devices still require the user to operate step by step, and especially for some complicated interaction tasks, the user still has complicated operations and low efficiency.

Disclosure of Invention

The application provides a device interaction method and device, which aim to solve the problem that in the prior art, device interaction operation is complex.

In a first aspect, an embodiment of the present application provides an apparatus interaction method, which specifically includes: first, a first electronic device generates a radio frequency field, the first electronic device comprising a near field communication, NFC, controller. Then, the first electronic device detects the stay time of the NFC label of the second electronic device in the radio frequency field; if the stay time is longer than the first time threshold and shorter than the second time threshold, the first electronic equipment executes the first type of interaction task; and if the stay time is greater than or equal to the second time threshold, the first electronic equipment executes the second type of interaction task.

Therefore, the device interaction tasks are distinguished according to the stay time through detecting the stay time of the NFC label in the radio frequency field of the NFC equipment and based on the preset time threshold. That is, when the dwell time is longer than the first time threshold and shorter than the second time threshold (which may be referred to as a short touch or a short touch), the first type of interaction task is executed, and when the dwell time is longer than the second time threshold (which may be referred to as a long touch or a long touch), the second type of interaction task is executed. Therefore, the short touch and the long touch are distinguished through the stay time, the first type of interaction task corresponding to the short touch and the second type of interaction task corresponding to the long touch are respectively defined, a user can realize different equipment interaction operations through the simple short touch and the simple long touch, the user operation is further simplified, and the equipment interaction efficiency is improved.

By way of example and not limitation, the first electronic device is a mobile phone and the second electronic device is a smart speaker. At this time, the following are preset: the first type of interaction task is to play the next song, and the second type of interaction task is to initialize configuration. The user can control the intelligent sound box to play the next song curve through simple short touch operation, or carry out initialization configuration on the intelligent sound box through simple long touch operation. The operation is simple and convenient, and the interaction efficiency is high.

It is to be noted that the stay time period may be a continuous stay time period; it is also possible to be a non-duration stay time period, but a time period obtained by adding a plurality of duration stay time periods. The specific meaning of the stay time is different, and the detection mode of the stay time is correspondingly different.

In a possible implementation manner of the first aspect, if the stay duration is a duration stay duration, the time when the NFC tag enters the radio frequency field and the time when the NFC tag leaves the radio frequency field may be recorded, and a difference between the two times is the stay duration. That is to say, the process of the first electronic device detecting the stay time of the NFC tag of the second electronic device in the radio frequency field may include: the method comprises the steps that first electronic equipment obtains first time when an NFC label enters a radio frequency field; the first electronic equipment acquires a second time when the NFC tag leaves the radio frequency field; the first electronic device takes a difference between the first time and the second time as the stay time period.

In a possible implementation manner of the first aspect, if the dwell time duration means a non-sustained dwell time duration, a plurality of sustained dwell time durations need to be calculated, and then the plurality of sustained dwell time durations are added to obtain the dwell time duration.

That is to say, the process of the first electronic device detecting the stay time of the NFC tag of the second electronic device in the radio frequency field may include:

if at least two NFC connections are established between the first electronic device and the second electronic device within a preset time period, and the difference value between the disconnection time of the previous NFC connection and the establishment time of the next NFC connection in any two adjacent NFC connections is smaller than a third time threshold value, the first electronic device obtains the duration of the continuous stay time of the NFC label corresponding to each NFC connection within the preset time period in the radio frequency field;

and the first electronic equipment adds the continuous stay time corresponding to each NFC connection to obtain an addition sum, and the addition sum is used as the stay time.

It is noted that when the NFC tag enters the radio field of the NFC device, the first electronic device and the second electronic device establish an NFC connection, and if the NFC tag is always within the radio field of the NFC device, the NFC device is not disconnected. When the NFC tag leaves the radio frequency field of the NFC device, the NFC connection of the first electronic device and the second electronic device is disconnected. One NFC connection corresponds to one NFC connection setup time and one NFC connection disconnection time.

If the NFC tag continuously and repeatedly enters the radio frequency field and leaves the radio frequency field, the NFC connection is continuously established and disconnected between the first electronic device and the second electronic device. In this way, there may be multiple NFC connections within the preset time period, i.e., the first electronic device and the second electronic device perform operations of establishing and disconnecting NFC connections multiple times within the preset time period.

In this implementation manner, when the difference between the disconnection time of the previous NFC connection and the establishment time of the next NFC connection is set to be smaller than the third time threshold, a plurality of continuous stay durations are recorded, and the sum of the plurality of continuous stay durations is used as the stay duration, so that the detection accuracy of the stay duration can be further improved, and the operation limitation of the user is reduced.

In a possible implementation manner of the first aspect, the second type of interaction task may include only one interaction task, or may include at least two interaction tasks. When the second type of interaction task comprises at least two interaction tasks, after the interaction is determined as the long touch according to the relation between the stay time and the time threshold, the target interaction task can be further determined according to other information. That is, the process of the first electronic device executing the second type of interaction task may include:

the method comprises the steps that first electronic equipment obtains NFC label information of second electronic equipment;

and the first electronic equipment determines a target interaction task from the second type of interaction tasks according to the NFC label information and executes the target interaction task.

For example, the second type of interaction tasks includes three interaction tasks of initialization configuration, connection establishment and disconnection, and whether the initialization configuration is performed or the connection or the disconnection is determined according to the NFC tag information.

In one possible implementation manner of the first aspect, the NFC tag information may include device information. At this time, the determining, by the first electronic device, the target interaction task from the second type of interaction tasks according to the NFC tag information, and executing the target interaction task may include:

and if the first electronic equipment does not have information consistent with the equipment information, the first electronic equipment takes the initialization configuration as a target interaction task and carries out initialization configuration on the second electronic equipment.

And if the information consistent with the equipment information exists in the first electronic equipment and the existing connection does not exist between the first electronic equipment and the second electronic equipment, the first electronic equipment takes the established connection as a target interaction task and establishes communication connection with the second electronic equipment.

And if the information consistent with the equipment information exists in the first electronic equipment and the existing connection exists between the first electronic equipment and the second electronic equipment, the first electronic equipment takes the disconnection as a target interaction task and disconnects the existing connection with the second electronic equipment.

In a possible implementation manner of the first aspect, the first electronic device may also automatically recommend the application according to a usage frequency and a usage preference of the user. That is, after the first electronic device establishes a connection as a target interaction task and establishes a communication connection with the second electronic device, the method may further include:

the method comprises the steps that a first electronic device determines an application to be recommended according to the use frequency and use preference of a user;

the first electronic equipment displays the visual pattern of the application to be recommended in a preset area.

In a second aspect, an embodiment of the present application provides a device interaction apparatus, which is applied to a first electronic device including a Near Field Communication (NFC) controller, and the apparatus may include:

the radio frequency field generating module is used for generating a radio frequency field;

the stay time detection module is used for detecting the stay time of the NFC tag of the second electronic device in the radio frequency field;

the first interaction module is used for executing a first type of interaction task if the stay time is longer than a first time threshold and shorter than a second time threshold;

and the second interaction module is used for executing the second type of interaction task if the stay time is greater than or equal to the second time threshold.

In a possible implementation manner of the second aspect, the staying duration detecting module is specifically configured to: acquiring first time when the NFC tag enters a radio frequency field; acquiring a second time when the NFC tag leaves the radio frequency field; the difference between the first time and the second time is taken as the dwell period.

In a possible implementation manner of the second aspect, the staying duration detecting module is specifically configured to: if at least two NFC connections are established between the first electronic device and the second electronic device within a preset time period, and the difference value between the disconnection time of the previous NFC connection and the establishment time of the next NFC connection in any two adjacent NFC connections is smaller than a third time threshold, acquiring the duration of the stay time of an NFC label corresponding to each NFC connection within a radio frequency field within the preset time period; and adding the duration stay time corresponding to each NFC connection to obtain an addition sum, and taking the addition sum as the stay time.

Detailed Description

In the prior art, user interaction actions are not distinguished according to the stay time, and then different interaction tasks are not triggered according to different user interaction actions. In other words, the prior art only corresponds to one interactive task regardless of the dwell time. For example, in the existing "one touch connection" function, no matter how long the touch time of the mobile phone and the computer is, the triggered interaction task is to establish connection. Therefore, other interactive operations of the user are still more complicated, and the interaction efficiency of the device is still lower.

In the embodiment of the application, the user interaction is distinguished through the stay time and the time threshold of the NFC tag in the radio frequency field of the NFC equipment. For convenience of description, the interactive action corresponding to the staying time length being greater than the first time threshold and less than the second time threshold is referred to as a short-time touch or a short touch, and the interactive action corresponding to the staying time length being greater than or equal to the second time threshold is referred to as a long-time touch or a long touch. Therefore, the user can realize some more complicated interactive operations through simple long touch and short touch, the user interactive operations are further simplified, and the equipment interactive efficiency is improved.

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application.

The NFC device refers to an electronic device integrated with an NFC controller, and the electronic device may include an NFC antenna and a security module in addition to the NFC controller. The NFC device may generate an NFC radio frequency field, which may also be referred to as an NFC inductive region, based on the integrated NFC device.

In this embodiment of the application, the types of the NFC device and the electronic device carrying the NFC tag may be arbitrary, that is, the types of the first electronic device and the second electronic device are arbitrary. For example, the first electronic device is a mobile phone, the second electronic device is a smart speaker, the mobile phone includes an NFC controller, and the smart speaker includes an NFC tag. Based on the type diversity of the first electronic device and the second electronic device, the application scenarios of the embodiment of the application are also diversified. For example, the interaction scene of the mobile phone and the smart sound box, the interaction scene of the mobile phone and the smart air conditioner, the interaction scene of the mobile phone and the smart desk lamp, the interaction scene of the mobile phone and the smart bracelet, and the like.

By way of example and not limitation, several scenarios that may be involved with embodiments of the present application will be illustrated below.

Interactive scene of mobile phone and intelligent sound box

Under this scene, cell-phone and smart speaker can both support the NFC function. The mobile phone reads the NFC label information of the intelligent sound box through the NFC controller.

The first type of interaction task corresponding to the short touch is specifically playing the next song, namely after the mobile phone judges that the user interaction is taken as the short touch, the intelligent sound box is controlled to play the next song.

The second type of interaction task corresponding to the long touch is an interaction task for switching the connection mode of the equipment, and the interaction task comprises three tasks, namely initialization configuration, Bluetooth connection establishment and Bluetooth connection disconnection. At this time, after the mobile phone determines that the user interaction is a long touch, it can also determine which interaction task of the second type of interaction tasks is executed according to other parameters.

Referring to fig. 1, which is a schematic view of an interaction scene between a mobile phone and a smart speaker, as shown in fig. 1, a mobile phone 11 generates an NFC radio frequency field 14, and an NFC tag 13 is disposed on a smart speaker 12. The NFC radio frequency field of the mobile phone is continuously close to the NFC label of the intelligent sound box, and when the distance between the mobile phone and the intelligent sound box is smaller than a certain distance, the NFC label enters the NFC radio frequency field. The mobile phone records the time of the NFC tag entering the radio frequency field, records the time of the NFC tag leaving the radio frequency field, and determines the stay time of the NFC tag in the radio frequency field according to the recorded entering time and leaving time.

The mobile phone 11 determines whether to touch the long stamp or the short stamp according to the detected staying time and a preset time threshold.

By way of example and not limitation, the first time threshold is 0.1s and the second time threshold is 0.3 s. Namely, if the stay time is longer than 0.1s and shorter than 0.3s, the short touch is judged; and if the stay time is longer than 0.3s, the touch is determined to be long. At this time, if the staying time detected by the mobile phone 11 is 0.2s, the short touch is considered, and the song-cutting interaction task is triggered. Specifically, the mobile phone 11 controls the smart speaker 12 to play the next song. In a specific application, the mobile phone 11 may send the audio data of the next song to the smart sound box 12 in a bluetooth or Wi-Fi manner, so that the smart sound box 12 plays the audio data after receiving the audio data of the next song. Certainly, the mobile phone 11 may also send a song switching instruction to the smart sound box, where the song switching instruction is used to instruct the smart sound box 12 to automatically obtain audio data of a next song from the local or cloud, and play the audio data.

If the staying time detected by the mobile phone 12 is 0.4s, the long touch is determined because the staying time is greater than 0.3 s. After the long touch is determined, since the second type of interactive task includes a plurality of interactive tasks, which interactive task is to be executed may be determined according to some parameters.

Specifically, after determining the long touch, if the device information of the smart speaker, for example, the device name and the device type, is not stored locally in the mobile phone 11, it may be determined that the smart speaker is an unused new device, and an initial configuration interaction task is triggered. Namely, the mobile phone 11 automatically performs initialization configuration on the smart speaker. The process of initializing the configuration of the mobile phone 11 may be specifically shown in fig. 2, as shown in fig. 2, after the mobile phone triggers the initialization configuration interaction task, a pop-up box pops up on the interface of the mobile phone, and the pop-up box displays "identify available new devices, pair them, and share Wi-Fi password", and displays that the smart speaker is "huabei AI speaker". In addition, the mobile phone also shares Wi-Fi information connected with the mobile phone to the intelligent sound box. If the user clicks the 'pairing' button in the elastic frame, the mobile phone begins to share the network with the intelligent sound box, meanwhile, the mobile phone can automatically download the intelligent sound box APP, and the mobile phone and the intelligent sound box are successfully paired. After the mobile phone and the smart sound box are successfully paired, the mobile phone can display some application icons for the user to select after the prompt message of successful pairing is displayed in the pop-up box.

In the process of carrying out initial configuration on new equipment, a user only needs to contact the mobile phone with the intelligent sound box for more than 3 seconds to complete the initial configuration operation of the intelligent sound box, and the method is simple to operate and high in equipment interaction efficiency. However, in the prior art, if the new device needs to be initialized and configured, the operation is very complicated, and the efficiency is low. Still use intelligent audio amplifier as an example, the user needs the manual bluetooth mode of opening intelligent audio amplifier to manual and intelligent audio amplifier establish the bluetooth and be connected, then manual download intelligent audio amplifier APP. Compared with the prior art, the long-touch interaction task is further divided, so that the operation is simple and the efficiency is high.

When the mobile phone 11 determines that the user interaction is a long touch, it is further determined that the device information of the smart sound box is stored locally in the mobile phone, which indicates that the smart sound box is a smart sound box that has been subjected to process initialization configuration. At this time, the mobile phone 11 may determine whether to establish a bluetooth connection with the smart speaker, and if there is no existing bluetooth connection between the mobile phone 11 and the smart speaker 12, an interaction task of establishing a connection may be triggered, that is, the mobile phone automatically establishes a bluetooth connection with the smart speaker. Specifically, the interface schematic diagram in the interaction scene between the mobile phone and the smart speaker shown in fig. 3 may be referred to, as shown in fig. 3, when it is determined that the user interaction is a long touch and no bluetooth connection is currently established with the smart speaker, the mobile phone automatically triggers an interaction task of establishing a connection and establishes a bluetooth connection with the smart speaker. Then, the mobile phone pops up a popup box of 'Bluetooth connected'. Also displayed within the bullet box is an icon of a recommended application that is determined according to the frequency of use and usage preferences of the user. Therefore, after the Bluetooth connection between the mobile phone and the intelligent sound box is established, the application program required to be opened can be selected by clicking the corresponding icon.

The mobile phone 11 determines that the user interaction is a long touch, and an existing bluetooth connection already exists between the mobile phone 11 and the smart speaker 12. At this moment, the disconnected interactive task can be triggered, namely, the mobile phone is disconnected from the Bluetooth connection with the intelligent sound box. Specifically, referring to the interface schematic diagram in the interaction scenario between the mobile phone and the smart sound box shown in fig. 4, as shown in fig. 4, after the mobile phone 11 disconnects the bluetooth connection with the smart sound box 12 by long touch, the mobile phone pops up a prompt box that "the bluetooth is disconnected".

Therefore, the long touch and the short touch are distinguished, and the interaction action corresponding to the long touch is further subdivided, so that the user can realize the fussy interaction operation as much as possible by simply long touch and short touch interaction operation, the user interaction operation is further simplified, and the equipment interaction efficiency is improved.

Of course, in other embodiments, the second type of interaction task corresponding to the long touch may have only one interaction task, for example, the second type of interaction task may include only the above initialization configuration task.

In addition, the user interaction action corresponding to the long touch can be that the user touches the mobile phone with the intelligent sound box for more than 3 seconds, and the mobile phone is not in contact with the intelligent sound box any more after 3 seconds; the mobile phone can also be placed on the intelligent sound box all the time, namely, the mobile phone and the intelligent sound box are kept in a contact state all the time.

It should be noted that the interaction tasks corresponding to the long touch and the short touch can be configured by the user. Specifically, the user can configure the interaction tasks corresponding to the long touch and the short touch in an interaction task configuration mode. For example, the user may configure the short-tap interaction task to establish a bluetooth connection and the long-tap interaction task to play the next song. That is to say, the long touch and the short touch correspond to which kind of interactive tasks, and how many interactive tasks are included in each kind of interactive tasks can be configured by the user according to the use habit and the requirement of the user.

Interactive scene of mobile phone and intelligent desk lamp

Referring to the schematic view of the interaction scene of the mobile phone and the intelligent desk lamp shown in fig. 5, as shown in fig. 4, the NFC tag is arranged on the intelligent desk lamp, and the mobile phone reads the NFC tag through the generated NFC sensing area to establish NFC connection. Similar to the interaction scenario between the mobile phone and the smart sound box corresponding to fig. 1, some complex interaction operations can be implemented between the mobile phone and the smart desk lamp by simply long and short touch, so as to simplify the user operation and improve the interaction efficiency of the device.

As an example and not by way of limitation, the interaction task corresponding to the short touch is turning off and turning on a light, in a specific application, after the mobile phone determines that the user interaction is short through the stay time, the on-off state of the desk lamp is further determined, and if the current state of the intelligent desk lamp is turning on, the light-off interaction task is triggered. Otherwise, if the current state of the intelligent desk lamp is the lamp turning-off state, the lamp interaction task is triggered.

The interaction tasks corresponding to the long touch include initialization configuration and adjustment of color temperature. At this time, after the mobile phone judges that the user interaction action is a long touch through the stay time, whether the equipment information of the intelligent desk lamp is stored locally or not can be judged, if yes, an interaction task of adjusting the color temperature is triggered, for example, the mobile phone controls the intelligent desk lamp to adjust from cold light to warm light. If the device information of the intelligent desk lamp is not stored locally in the mobile phone, the intelligent desk lamp is considered to be a new device, initialization configuration needs to be carried out first, an interaction task of the initialization configuration is triggered, and initialization configuration operation is executed.

It should be noted that the scene is similar to the interaction scene of the mobile phone and the smart sound box, and some similar or identical contents may be referred to each other, which is not described herein again.

After exemplarily introducing application scenarios that may be involved in the embodiments of the present application, the following describes in detail the technical solutions provided in the embodiments of the present application.

Referring to fig. 6, which is a schematic flow chart diagram of a device interaction method provided in an embodiment of the present application, the method may include the following steps:

step S601, a first electronic device generates a radio frequency field, where the first electronic device includes a near field communication NFC controller.

Step S602, the first electronic device detects a dwell time of the NFC tag of the second electronic device in the radio frequency field. If the staying time is longer than the first time threshold and shorter than the second time threshold, the step S603 is entered; otherwise, if the staying time is greater than or equal to the second time threshold, the process proceeds to step S604.

It should be noted that the dwell time may be a duration dwell time, where the duration dwell time refers to that the NFC tag is always in the NFC sensing area; it is also possible to be a non-duration stay time period, but a time period obtained by adding a plurality of duration stay time periods. The specific meaning of the stay time is different, and the detection mode of the stay time is correspondingly different.

In some embodiments, if the stay time period is a duration stay time period, the time when the NFC tag enters the radio frequency field and the time when the NFC tag leaves the radio frequency field may be recorded, and the difference between the two times is the stay time period. Specifically, the first electronic device acquires a first time when the NFC tag enters the radio frequency field, the first electronic device acquires a second time when the NFC tag leaves the radio frequency field, and finally, the first electronic device takes a difference between the first time and the second time as a stay time.

At this time, if long touch needs to be realized, a contact state needs to be maintained between the NFC sensing area of the first electronic device and the NFC tag of the second electronic device within a certain time. During this time, if the user carelessly leaves the NFC sensing area and the NFC tag in a non-contact state, the detected stay time may not coincide with the actual purpose of interaction of the user. For example, the user needs to implement a long-touch operation, but in the process, due to improper operation, the NFC tag leaves the NFC sensing area, and the mobile phone determines the user interaction as a short-touch operation according to the detected staying time, which is contrary to the actual purpose of the user. And because the NFC sensing area cannot be observed by naked eyes, the relatively constant distance between the first electronic device and the second electronic device can only be maintained by feel, which results in higher operation difficulty and more limitations for the user.

In order to solve the problem, the stay time detected by the first electronic device is more consistent with the purpose of the user, the operation difficulty and the operation limitation of the user are reduced, and the detection mode of changing the stay time can be used for realizing the purpose. This will be described below.

In other embodiments, if the dwell period means a non-sustained dwell period, then a plurality of sustained dwell periods may be calculated and then added to provide the dwell period.

Specifically, if at least two times of NFC connection are established between the first electronic device and the second electronic device within a preset time period, and a difference between disconnection time of a previous NFC connection and establishment time of a subsequent NFC connection in any two adjacent NFC connections is smaller than a third time threshold, the first electronic device obtains a duration of stay of an NFC tag in the radio frequency field corresponding to each NFC connection within the preset time period. Then, the first electronic device adds the duration of stay corresponding to each NFC connection to obtain a sum, and the sum is used as the stay duration.

The preset time period may be set according to actual needs. For example, the preset time period may be 10s, 15s, or 30 s.

For example, taking the interaction scenario of fig. 1 as an example, if a long-touch operation needs to be implemented, a user may place a mobile phone on the top of the smart speaker, so that the NFC sensing area and the NFC tag always maintain a contact state, and when the duration lasts for more than 3 seconds, the user may regard the long-touch operation; the user can also control the mobile phone and the NFC label area of the smart sound box to keep a relatively constant distance, and the distance can enable the NFC sensing area and the NFC label to be in a contact state.

In other cases, the user can also perform long touch operations by picking up and putting down the phone with high frequency. The high frequency may be defined by setting a preset time period and a magnitude of a difference between disconnection time and establishment direction of two adjacent NFC connections. By way of example and not limitation, at 10s, the mobile phone and the smart speaker establish 3 NFC connections, each corresponding to one NFC connection establishment time and one NFC connection disconnection time. The duration of the 3 NFC connections is 0.2s, 0.1s, and 0.1s, respectively, and the disconnection time of the two adjacent NFC connections and the disconnection time of the next NFC connection are 0.1s and 0.15s, respectively. The third time threshold is preset to 0.2 s. At this time, the duration corresponding to the three NFC connections may be considered to be valid, and the 3 durations are added to obtain the duration, that is, 0.2s +0.1s +0.1s is 0.4s > 0.3s, and it is considered that the user takes up and puts down the mobile phone at a high frequency of 10s also belongs to the long touch operation.

Of course, the manner of detecting the stay period is not limited to the above-mentioned two manners.

Step S603, the first electronic device executes the first type of interaction task.

And step S604, the first electronic equipment executes the second type of interaction tasks.

It should be noted that the types of the first-type interactive tasks and the second-type interactive tasks and the number of tasks included may be configured by the user as needed or may be preset.

By way of example and not limitation, the first electronic device is a cell phone and the second electronic device is a smart air conditioner, both of which support NFC functionality. At this time, the first type of interaction task is to turn on the air conditioner, and the second type of interaction task is to turn off the air conditioner.
