Description

Equipment interaction method and device

Technical Field

The application relates to the technical field of near field communication (Near Field Communication, NFC), in particular to a device interaction method and device.

Background

Currently, users typically have a plurality of terminal devices in different forms, such as mobile phones, tablets, smart speakers, and smart desk lamps. With the continuous development of full scene technology, device interactions among multiple terminal devices are increasing.

There are ways in the prior art to implement device interactions based on NFC. Specifically, after the NFC induction area of the mobile phone is contacted with the NFC label on the notebook computer, the mobile phone and the NFC label are automatically paired, communication connection is established, and connection between the mobile phone and the notebook computer is established.

In the existing device interaction mode, after the NFC induction area is contacted with the NFC tag, a predefined interaction task is automatically executed, so that a user operation path can be shortened to a certain extent, and user operation is simplified. However, only one interaction task is predefined, other interactions between devices still need to be operated step by the user, and especially for some relatively complex interaction tasks, the operation of the user is still complex, and the efficiency is low.

Disclosure of Invention

The application provides a device interaction method and device, which are used for solving the problem of complex device interaction operation in the prior art.

In a first aspect, an embodiment of the present application provides a device interaction method, where the method 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 residence 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 smaller 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 device executes the second type of interaction task.

From the above, according to the embodiment of the application, the residence time of the NFC tag in the radio frequency field of the NFC device is detected, and then the device interaction tasks are distinguished according to the residence time based on the preset time threshold. I.e. when the dwell time is longer than a first time threshold and less than a second time threshold (which may be referred to as a short touch or short touch), the first type of interactive task is performed, and when the dwell time is longer than the second time threshold is obtained (which may be referred to as a long touch or long touch), the second type of interactive task is performed. In this way, the short touch and the long touch are distinguished through the stay time, and the first type interaction task corresponding to the short touch and the second type interaction task corresponding to the long touch are respectively defined, so that different device interaction operations can be realized through simple short touch and long touch, the user operation is further simplified, and the device interaction efficiency is improved.

By way of example and not limitation, the first electronic device is a cell phone and the second electronic device is a smart speaker. At this time, the following is set in advance: the first type of interaction task is playing the next song, and the second type of interaction task is initializing configuration. The user can control the intelligent sound box to play the next song curve through simple short touch operation, or can perform initialization configuration on the intelligent sound box through simple long touch operation. The operation is simpler and more convenient, and the interaction efficiency is higher.

It should be noted that the above-mentioned stay period may be a continuous stay period; or may be a non-continuous residence time period, but a time period obtained by adding a plurality of continuous residence time periods. The specific meaning of the residence time is different, and the detection mode of the residence time is correspondingly different.

In a possible implementation manner of the first aspect, if the stay time is a continuous stay time, the time of entering the radio frequency field and the time of leaving the radio frequency field of the NFC tag may be recorded, and the difference between the two times is the stay time. That is, the process of detecting, by the first electronic device, a residence 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 tag enters a radio frequency field; the first electronic device obtains a second time when the NFC tag leaves the radio frequency field; the first electronic device uses the difference between the first time and the second time as the stay time.

In a possible implementation manner of the first aspect, if the duration of the stay means a non-continuous stay, a plurality of continuous stay lengths need to be calculated, and then the plurality of continuous stay lengths are added to obtain the stay length.

That is, the process of detecting, by the first electronic device, a residence time of the NFC tag of the second electronic device in the radio frequency field may include:

if the first electronic device and the second electronic device establish at least two times of NFC connection within the 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 times of NFC connection is smaller than a third time threshold, the first electronic device obtains the duration of the corresponding NFC tag in the radio frequency field in each time of NFC connection within the preset time period;

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

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

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

In the 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 a third time threshold, a plurality of continuous stay time lengths are recorded, and the sum of the plurality of continuous stay time lengths is taken as the stay time length, so that the detection accuracy of the stay time length can be further improved, and the operation restriction of a 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 includes at least two interaction tasks, after determining that the interaction is long-touched according to the relationship between the stay time and the time threshold, the target interaction task may be further determined according to other information. That is, the process of executing the second type of interaction task by the first electronic device may include:

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

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

For example, the second type of interaction task includes three interaction tasks of initializing configuration, establishing connection and disconnecting connection, and whether to perform the initializing configuration or establishing connection or disconnecting connection is determined according to the NFC tag information.

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

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

If the first electronic equipment has the information consistent with the equipment information and the existing connection does not exist between the first electronic equipment and the second electronic equipment, the first electronic equipment takes the connection establishment as a target interaction task and establishes communication connection with the second electronic equipment.

If the first electronic equipment has the information consistent with the equipment information and the existing connection exists between the first electronic equipment and the second electronic equipment, the first electronic equipment takes 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 further recommend the application program automatically according to a frequency of use and a preference of use 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 the use preference of a user;

the first electronic device displays a 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, applied to a first electronic device including a near field communication NFC controller, where the apparatus may include:

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

the stay time detection module is used for detecting the stay time of the NFC label 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 smaller 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 stay time duration detection module is specifically configured to: acquiring the first time when the NFC tag enters the 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 stay time.

In a possible implementation manner of the second aspect, the stay time duration detection module is specifically configured to: if the first electronic device and the second electronic device establish at least two times of NFC connection within the 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 times of NFC connection is smaller than a third time threshold value, the duration of the NFC label corresponding to each time of NFC connection within the preset time period in the radio frequency field is obtained; and adding the continuous residence time corresponding to each NFC connection to obtain an added sum, wherein the added sum is used as the residence time.

Detailed Description

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

In the embodiment of the application, the user interaction is distinguished by the residence time of the NFC tag in the radio frequency field of the NFC device and the time threshold. For convenience of description, the interaction corresponding to the dwell time longer than the first time threshold and smaller than the second time threshold is hereinafter referred to as a short touch or a short touch, and the interaction corresponding to the dwell time longer than or equal to the second time threshold is hereinafter referred to as a long touch or a long touch. Therefore, the user can realize some complicated interaction operations through simple long touch and short touch, so that the user interaction operation is further simplified, and the equipment interaction efficiency is improved.

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

NFC device refers to an electronic device integrated with an NFC controller, which 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 induction region, based on the integrated NFC device.

In the embodiment of the present 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 variety of the types of the first electronic device and the second electronic device, the application scene of the embodiment of the application also has variety. For example, the interaction scene of a mobile phone and a smart sound box, the interaction scene of a mobile phone and a smart air conditioner, the interaction scene of a mobile phone and a smart desk lamp, the interaction scene of a mobile phone and a smart bracelet, and the like.

By way of example, and not limitation, several scenarios in which embodiments of the present application may be involved will be described as examples.

Interaction scene of mobile phone and intelligent sound box

In this scenario, both the mobile phone and the smart speaker can support NFC functionality. The mobile phone reads 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 to play the next song, namely after the mobile phone judges that the user interaction is used 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 device, and the interaction task comprises three tasks, namely initializing configuration, establishing Bluetooth connection and disconnecting Bluetooth connection. At this time, after determining that the user interaction is long touch, the mobile phone may further determine which interaction task of the second type of interaction task is executed according to other parameters.

Referring to the schematic diagram of the interaction scenario between the mobile phone and the smart speaker shown in fig. 1, as shown in fig. 1, the mobile phone 11 generates an NFC radio frequency field 14, and the smart speaker 12 is provided with an NFC tag 13. The NFC radio frequency field of the mobile phone is continuously close to the NFC tag 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 tag enters the NFC radio frequency field. The mobile phone records the time of the NFC tag entering the radio frequency field and records the time of the NFC tag leaving the radio frequency field, and the residence time of the NFC tag in the radio frequency field is determined according to the recorded entering time and leaving time.

The mobile phone 11 determines whether to make a long touch or to make a short stamp based on the detected stay time length and a time threshold set in advance.

By way of example and not limitation, the first time threshold is 0.1s and the second time threshold is 0.3s. That is, if the stay time is longer than 0.1s and smaller than 0.3s, the short touch is judged; and if the stay time is longer than 0.3s, it is determined that the touch is long. At this time, if the dwell time detected by the mobile phone 11 is 0.2s, the mobile phone is considered as a short touch, 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 speaker 12 through bluetooth or Wi-Fi, so that the smart speaker 12 plays the audio data after receiving the audio data of the next song. Of course, the mobile phone 11 may also send a song cutting instruction to the smart speaker, where the song cutting instruction is used to instruct the smart speaker 12 to automatically obtain the audio data of the next song from the local or cloud end, and play the audio data.

If the dwell time detected by the handset 12 is 0.4s, a long touch is determined because the dwell time is longer than 0.3s. After the long touch is determined, since the second type of interaction task includes a plurality of interaction tasks, it is also possible to determine which interaction task to execute according to some parameters.

Specifically, after determining that the smart speaker is long touched, if the local device information of the smart speaker, for example, the device name and the device type, is not stored in the local device 11, it may be determined that the smart speaker is a new unused device, and an initialization configuration interaction task is triggered. I.e. the mobile phone 11 automatically performs an initial configuration to the smart speaker. The process of initializing configuration of the mobile phone 11 may be specifically shown in fig. 2, after the mobile phone triggers the task of initializing configuration interaction, a box is popped up on the mobile phone interface, where "identify available new device, pair with it, share Wi-Fi password" is displayed on the box, and the smart speaker is displayed as "HUAWEI 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 bullet frame, the mobile phone starts to share the network with the intelligent sound box, and 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 intelligent sound box are successfully paired, the mobile phone can display some application icons for users to select besides the pairing success prompt information in the bullet frame.

In the process of carrying out initialization configuration on new equipment, a user only needs to contact a mobile phone with the intelligent sound box for more than 3s, and the initialization configuration operation of the intelligent sound box can be completed, so that the operation is simple and the equipment interaction efficiency is higher. In the prior art, if the new equipment needs to be initialized and configured, the operation is very complicated and the efficiency is low. Still take intelligent audio amplifier as the example, the user needs manual bluetooth mode who opens intelligent audio amplifier to manual and intelligent audio amplifier establish bluetooth connection, then manual download intelligent audio amplifier APP again. Compared with the prior art, the method and the device have the advantages that the interaction tasks of long touch are further divided, so that the operation is simple and the efficiency is high.

When the mobile phone 11 determines that the user interaction is long touch, it further determines that the mobile phone locally stores the device information of the smart speaker, and indicates that the smart speaker is a smart speaker that has been configured by process initialization. At this time, the mobile phone 11 may determine whether to establish bluetooth connection with the smart speaker, and if no existing bluetooth connection exists between the mobile phone 11 and the smart speaker 12, the interaction task of establishing connection may be triggered, that is, the mobile phone automatically establishes bluetooth connection with the smart speaker. The interface schematic diagram of the interaction scene of the mobile phone and the intelligent sound box shown in fig. 3 can be participated, and as shown in fig. 3, when the mobile phone judges that the interaction of the user is long touch and no bluetooth connection is established with the intelligent sound box, the interaction task for establishing connection is automatically triggered to establish bluetooth connection with the intelligent sound box. Then, the mobile phone pops up a "Bluetooth connected" bullet frame. Also displayed within the bullet box is an icon of a recommended application that is determined based on the frequency of use and the preference of use of the user. Thus, after the Bluetooth connection is established between the mobile phone and the intelligent sound box, an application program to be opened can be selected by clicking a corresponding icon.

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

From the above, not only the long touch and the short touch are distinguished, but also the interaction action corresponding to the long touch is further subdivided, so that the user can realize as many complicated interaction operations as possible by simply performing the interaction operation of the long touch and the short touch, thereby further simplifying the interaction operation of the user and improving the interaction efficiency of the device.

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

In addition, the user interaction action corresponding to the long touch can be that the user contacts the mobile phone with the intelligent sound box for more than 3s, and the mobile phone is not contacted with the intelligent sound box after 3 s; the mobile phone can be placed on the intelligent sound box all the time, namely the mobile phone and the intelligent sound box keep in a contact state all the time.

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

Interaction scene of mobile phone and intelligent desk lamp

Referring to the schematic diagram of the interaction scenario between the mobile phone and the intelligent desk lamp shown in fig. 5, as shown in fig. 4, the intelligent desk lamp is provided with an NFC tag, and the mobile phone reads the NFC tag through the generated NFC sensing area to establish NFC connection. Similar to the interaction scenario of the mobile phone and the intelligent sound box corresponding to fig. 1, some complicated interaction operations can be realized between the mobile phone and the intelligent desk lamp through simple long touch and short touch, so that user operation is simplified, and equipment interaction efficiency is improved.

As an example, but not limited to, the interaction task corresponding to the short touch is turning off and on, in a specific application, after the mobile phone determines that the user interaction is used as the short touch through the stay time, the switching 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 lamp turning-off, the lamp interaction task is touched on.

The interaction tasks corresponding to the long touch comprise initializing configuration and adjusting color temperature. At this time, after the mobile phone judges that the user interaction is long touch through the stay time, it can judge whether the device information of the intelligent desk lamp is stored locally, if so, 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 mobile phone does not store the equipment information of the intelligent desk lamp locally, the intelligent desk lamp is considered to be a new equipment, the initialization configuration is needed, an interaction task of the initialization configuration is triggered, and the initialization configuration operation is executed.

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

After an application scenario possibly related to the embodiment of the present application is exemplarily introduced, a technical solution provided by the embodiment of the present application will be described in detail below.

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

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

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

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

In some embodiments, if the dwell time is a continuous dwell time, the time of entering the radio frequency field and the time of leaving the radio frequency field of the NFC tag may be recorded, and the difference between the two times is the dwell time. Specifically, the first electronic device obtains a first time when the NFC tag enters the radio frequency field, the first electronic device obtains a second time when the NFC tag leaves the radio frequency field, and finally, the first electronic device uses a difference value between the first time and the second time as a stay time.

At this time, if long touch is required, a touch state is required to be maintained between the NFC sensing area of the first electronic device and the NFC tag of the second electronic device for a certain period of time. During this time, if the user is careful such that the NFC sensing area and the NFC tag are in a non-contact state, the detected dwell time may not coincide with the user's actual interaction purpose. For example, the user needs to implement a long-touch operation, but, due to incorrect operation in the process, the NFC tag leaves the NFC sensing area, and the mobile phone determines that the user interaction is a short-touch operation according to the detected stay time, which is contrary to the actual purpose of the user. However, the NFC sensing area is not visible to the naked eye, and only a relatively constant distance between the first electronic device and the second electronic device can be maintained by feel, which results in a higher difficulty and more limitation of the user.

In order to solve the problem, the residence time detected by the first electronic device is more consistent with the purpose of the user, so that the operation difficulty and the operation restriction of the user are reduced, and the detection mode of the residence time can be changed. This will be described below.

In other embodiments, if the duration of stay means a non-continuous duration of stay, then multiple continuous durations of stay need to be calculated, and then the multiple continuous durations of stay are added to obtain the duration of stay.

Specifically, if the first electronic device and the second electronic device establish NFC connection at least twice within the preset time period, and a difference between a disconnection time of a previous NFC connection and an establishment time of a next NFC connection in any two adjacent NFC connections is smaller than a third time threshold, the first electronic device obtains a duration of an NFC tag corresponding to each NFC connection in the preset time period in a radio frequency field. And then, the first electronic equipment adds the continuous stay time corresponding to each NFC connection to obtain an added sum, and the added sum is used as the stay time.

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

For example, taking the interaction scenario of fig. 1 as an example, if a long touch operation is required, a user may place a mobile phone on top of the smart speaker, so that the NFC sensing area and the NFC tag always remain in a contact state, and when the duration is more than 3s, the long touch operation may be considered; the user may also control the NFC tag area of the phone and the smart box to maintain a relatively constant distance that may place the NFC sensing area and the NFC tag in contact.

In other cases, the user can also realize long touch operation by picking up and putting down the mobile phone at a high frequency. The high frequency may be defined by setting a preset period of time, and the magnitude of the difference between the break time and the establishment of the two adjacent NFC connections. By way of example and not limitation, at 10s, the handset and the smart box establish 3 NFC connections, one NFC connection setup time and one NFC connection disconnection time for each NFC connection. The duration of the 3 NFC connections is 0.2s, 0.1s and 0.1s, respectively, and the disconnection time of the NFC connection of the two adjacent times and the disconnection time of the next NFC connection are 0.1s, 0.15s, respectively. The third time threshold is preset to 0.2s. At this time, the duration corresponding to the three NFC connections may be considered to be effective, and the 3 duration stay durations are added to obtain the stay duration, that is, 0.2s+0.1s+0.1s=0.4s > 0.3s, and the user is considered to pick up and put down the mobile phone at a high frequency of 10s to be also a long-touch operation.

Of course, the manner of detecting the stay length 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 task.

It should be noted that, the types of the first type of interaction task and the second type of interaction task and the number of the included tasks may be configured by the user according to the needs, 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 supporting 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.
