Detailed Description
The design concept of the invention is as follows: the combination of mobile charging and far-field sound pickup functions is realized on the accessory, and intelligent automatic switching can be performed with equipment (such as a mobile phone or a tablet). When the user charges the equipment, the user can continue to use the equipment without hands, and the function switching between the equipment and the accessory is intelligently carried out, so that the functions of the accessory are enriched, the intelligent degree of the accessory and the equipment is improved, the operation steps of the user are saved, and the user experience is improved.
Fig. 1 is a flowchart of an interactive implementation method in an embodiment of the present invention, and referring to fig. 1, the interactive implementation method in the embodiment is applied to an accessory, and includes the following steps:
step S101, judging whether equipment is placed on the accessory or not to obtain a judgment result;
and S102, establishing wireless communication connection with the equipment according to the judgment result of the equipment placed on the accessory, and executing the function of voice interaction mediation between the equipment and the user after the wireless communication connection is established.
As shown in fig. 1, in the interaction implementation method of this embodiment, a device is or is not placed on an accessory, if it is determined that the device is placed on the accessory, a wireless communication connection with the device is established, and the accessory intelligently and automatically executes functions mediated by the device and voice interaction of the user, such as far-field sound pickup and voice playing output, which is equivalent to switching a hands-free function of the device to the accessory, and enriches functions of the accessory, simplifies a series of operation steps of clicking an interface by the user, selecting a search accessory, establishing a connection, and the like, improves the intelligence degree of the accessory and the device, and improves user experience.
In one embodiment of the present invention, the determining whether the device is placed on the accessory in step S101 includes: and detecting the current pressure state borne by the fitting and determining whether equipment is placed on the fitting according to the pressure state. Specifically, the pressure value acquired from the pressure sensor within a preset time period (for example, 2 minutes) from the time when the device is placed on the accessory is obtained, an average value of the obtained pressure values is calculated, and if the average value is less than or equal to a first pressure threshold value, it is determined that the accessory is currently in a second pressure state where the device is not placed; if the average is greater than the first pressure threshold, it is determined that the fitting is currently in a first pressure state in which the device is positioned.
Considering that most of the functions of the accessory are relatively single, for this reason, the accessory of the present embodiment also charges the device while performing the function of mediating the device with the user voice interaction. That is to say, besides the functions of sound pickup and playing of the device, the device can be charged, so that the effect of normally using the hands-free function while charging the device is achieved, and the user experience is improved.
For example, when it is detected that the pressure state of the accessory is switched from the first pressure state to the second pressure state, the accessory stops charging the device; when it is detected that the pressure state of the accessory is switched from the second pressure state to the first pressure state, the accessory starts charging the device. Here, charging the device includes: controlling an accessory battery or a power supply externally connected with the accessory to wirelessly charge equipment, wherein the equipment comprises equipment with a wireless charging receiver; or, controlling the accessory battery or a power supply externally connected with the accessory to charge the equipment contacting the charging interface, wherein the equipment comprises equipment with a terminal contacting the charging interface of the accessory. In consideration of the particularity of wireless charging, in order to avoid misoperation, in this embodiment, before controlling the accessory battery or the power supply externally connected to the accessory to wirelessly charge the device, the wireless charging circuit further sends an inquiry signal to the device, and the accessory battery or the power supply externally connected to the accessory is controlled to start wireless charging of the device according to feedback information for the inquiry signal returned by the device.
As can be seen from the above, in this embodiment, two charging modes are provided, one is a non-contact wireless charging mode, and the other is a contact charging mode, which depend on different devices, and when a device is a device supporting wireless charging, for example, a wireless charging device such as a wireless receiving coil is installed on the device, in this embodiment, an accessory controls a battery or an external power supply to wirelessly charge the device. When the wireless charging device such as a wireless receiving coil is not installed on the equipment, the accessory is in mutual contact with a charging terminal of the equipment through a charging interface of the accessory to charge the equipment, and the charging requirements of different equipment are met.
Considering that the types of the devices are different and the required charging currents are different, in this embodiment, charging the device further includes: the magnitude of the charging current value is determined according to the type of the device, specifically, if the device belongs to a first type (a low-current device, such as a mobile phone), the charging current value is adjusted to a first current value adapted to the first type of device, and if the device belongs to a second type (a high-current device, such as a tablet), the charging current value is adjusted to a second current value adapted to the second type of device, and the second current value is larger than the first current value. Thereby preventing the current from being inconsistent and damaging the equipment.
In one embodiment of the present invention, the method shown in fig. 1 further comprises: if the pressure state of the accessory is detected to be switched from the first pressure state to the second pressure state, acquiring preset switching information from equipment; if the acquired switching information indicates that the device directly executes the voice interaction function with the user, the accessory disconnects the wireless communication connection with the device and stops executing the function intermediating the voice interaction of the device and the user; if the acquired switching information indicates that the function mediated by the device with the user voice interaction is to continue to be performed by the accessory, the accessory continues to maintain the wireless communication connection with the device and to perform the function mediated by the device with the user voice interaction.
In practice, there is still a case that it is desired to perform the far-field sound pickup and playing function by the accessory after the user takes the device off or takes the device off the accessory, and for this requirement, in this embodiment, when it is detected that the pressure state is switched from the first pressure state to the second pressure state, that is, after it is detected that the device is taken off the accessory, the accessory acquires preset switching information from the device, if the content of the switching information indicates disconnection, the wireless connection with the device is disconnected, and if the content of the switching information indicates that connection is maintained, the wireless connection with the device is continuously maintained, and the switching information is device information that the user previously inputs on the device, so that the user can freely select whether to continuously maintain connection with the accessory after taking the device off the accessory, thereby enhancing user satisfaction. Of course, the accessory may also acquire the switching information after the wireless communication connection is established, without having to wait until the pressure state is switched from the first pressure state to the second pressure state.
In one embodiment, the method shown in fig. 1 further comprises: in the process of continuously maintaining the wireless communication connection with the equipment, according to the trigger information of the preset connection interruption event acquired from the equipment, the wireless communication connection with the equipment is disconnected, so that the equipment directly executes the voice interaction function with the user; the preset connection interruption event comprises any one of the following: the equipment makes and receives calls; the equipment is static for a preset time; the shaking times of the equipment reach the preset times; the distance between the equipment and the accessories reaches a preset distance threshold value, and the maintaining time reaches a preset duration; or, according to the trigger information of the preset connection recovery event acquired from the equipment, reestablishing the wireless communication connection with the equipment and executing the function of voice interaction mediation between the equipment and the user; the preset connection recovery event comprises the completion of the equipment call.
In consideration of the situation, the accessory in this embodiment acquires trigger information of a preset connection interruption event of the device, and if the trigger information indicates that the device is in a call receiving state, the voice interaction intermediary function, namely, the far-field sound pickup and playing function, is switched back to the device.
In practical applications, besides the event that the connection is interrupted, such as making a call, the device may also be triggered to be interrupted, for example, the device is stationary for a preset time period, for example, the number of times the device is shaken reaches a preset number of times; for another example, the distance between the device and the accessory reaches a preset distance threshold, and the holding time (the holding time is the time accumulated when the device is held at the preset distance from the accessory) reaches a preset time length, and so on. When the above event occurs, the accessory of the present embodiment is made more intelligent by interrupting the connection state with the device.
It should be noted that the function of the accessory execution device and the user voice interaction intermediary of the present embodiment includes: receiving far-field voice information of a user, identifying the far-field voice information, and determining whether the far-field voice information contains a preset awakening word; if the far-field voice information contains a preset awakening word, sending a command word after the awakening word in the recognized far-field voice information to the equipment through wireless communication connection so that the equipment executes corresponding operation according to the command word, wherein the command word comprises any one of the following items: searching the network, inquiring information on the equipment, making/receiving calls and opening music; and receiving the voice of the equipment during the call or the audio information to be played on the equipment through wireless communication connection, and playing and outputting the voice or the audio information. That is, the user can perform voice interaction with the accessory as with the device, and the accessory is used as an intermediary for performing voice interaction between the device and the user, acquires the voice of the user, transmits the voice to the device, acquires the feedback voice information from the device, and plays and outputs the feedback voice information to the user. For example, if the user wants to open the music APP on the device to listen to the music, the user may send out a voice message, and the message may include a wakeup word and a command word, such as "watt force (name of accessory), please open the music, and play the song. The microphone or microphone array on the accessory picks up the voice signal and then performs voice recognition to determine that the wake-up word is watt force and the command word is an open music playing song, so that the open music playing song is sent to the device.
Thus, the functions of far-field interaction and playing are executed by the accessory, which is equivalent to the function switching between the accessory and the equipment, namely, the user voice acquisition, the audio playing and the like which are originally executed by the equipment are switched to the accessory for execution. Note: pickup and speech recognition are prior art, and reference may be made to the description in the prior art, which is not described in detail in this embodiment.
In addition, one implementation way of the process of establishing wireless communication connection between the accessory and the device is, for example, that after the accessory determines that the device is placed on the accessory, the accessory notifies the device to turn on the bluetooth through the wireless charging transmitting circuit, searches the bluetooth of the device and establishes the bluetooth wireless communication connection, so that the manual operation steps of a user are saved, and the intelligent and automatic level is improved.
Fig. 2 is a schematic flowchart of an interactive implementation method in another embodiment of the present invention, and referring to fig. 2, the interactive implementation method in this embodiment is applied to a device, and includes the following steps:
step S201, receiving a wireless communication connection establishment request sent by an accessory after the accessory detects that the equipment is placed on the accessory, and establishing wireless communication connection with the accessory according to the wireless communication connection establishment request;
step S202, receiving the processed user voice information sent by the accessory through the wireless communication connection, executing corresponding operation according to the user voice information, or sending the audio information to be played to the accessory through the wireless communication connection, and playing and outputting the audio information by the accessory.

In an embodiment of the present invention, in step S202 shown in fig. 2, receiving the processed far-field voice information sent by the accessory, and performing corresponding operations according to the far-field voice information includes: receiving a command word in the far-field voice information, and executing corresponding operation according to the command word, wherein the command word comprises any one of the following items: searching network information, inquiring equipment information, making/receiving calls and opening music.
That is, the device of the present embodiment receives a command word sent from the accessory by establishing a wireless connection with the accessory, and performs a corresponding operation according to the command word, thereby achieving an effect that the hands-free function can be normally used even if the device is placed on the accessory, and the operation corresponding to the voice command can be performed.
In practical application, the user can predefine whether the connection state of the accessory and the equipment is disconnected after the equipment is taken away from the accessory, so that the user is given more freedom and the participation degree of the user is enhanced.
Further, during use of the device, a variety of preset events may occur, which may trigger disconnection of the accessory, thereby facilitating use by the user. In one embodiment of the present invention, the method shown in fig. 2 further comprises: judging whether a preset connection interruption event is triggered or not in the process of maintaining wireless communication connection with the accessory, and sending triggering information of the preset connection interruption event to the accessory when the preset connection interruption event is triggered; the preset connection interruption event includes any one of: receiving and making a call; standing for a preset time; the shaking times reach the preset times; the distance between the accessory and the accessory reaches a preset distance threshold value, and the time is maintained for a preset time length.
The determination of whether the preset connection interruption event is triggered includes: acquiring information acquired by an acceleration sensor and a distance sensor on equipment, and judging that the equipment is making a call when the acceleration is greater than a first acceleration threshold and the distance between the equipment and the face of a user is less than a first distance threshold; when the accumulated time length of the acceleration of the equipment equal to 0 reaches the preset time length, judging that the equipment is static and reaches the preset time length; when the equipment is shaken, the acceleration is greater than a first acceleration threshold value, the equipment is confirmed to be shaken once successfully, the shaking times are counted, and when the counted times reach a first time threshold value, the times that the equipment is shaken are judged to reach the preset times; starting to accumulate time when the distance between the equipment and the accessory is increased and reaches a preset distance threshold, and judging that the distance between the equipment and the accessory reaches the preset distance threshold and the time is maintained to reach the preset time if the accumulated time reaches the preset time.
Therefore, the user can predefine (for example, through an application APP on the device) and set events for disconnecting the connection with the accessory, and the effect of disconnecting the connection with the accessory is realized by triggering the events, so that the flexibility is high, the normal use of the device by the user is not influenced, and the satisfaction degree of the user is improved.
The present embodiment also provides an accessory, comprising: the detector, a processor connected with the detector, and a sound pick-up and a loudspeaker connected with the processor; the detector is used for judging whether equipment is placed on the accessory or not, obtaining a judgment result and sending the judgment result to the processor; and the processor is used for establishing wireless communication connection with the equipment according to the judgment result of the equipment placed on the accessory, and controlling the sound pick-up and the loudspeaker to execute the function of mediating the voice interaction between the equipment and the user after the wireless communication connection is established.

Referring to fig. 7, a groove is provided on the side of the fitting in contact with the baffle, and a pressure bar (pressure sensor) is provided in the groove to detect the weight of the device, i.e., the pressure of the device against the fitting. In another embodiment of the invention, it is also possible to provide a spring on the surface of the fitting that can be brought into contact with the device, which spring is deformed after the device has been placed on the fitting, on the basis of which deformation it is determined that the device has been placed on the fitting. The accessory shown in fig. 7 illustrates a USB port to connect devices for external communication.
The operation of the fitting shown in fig. 7 will be described below with reference to fig. 8 and 9.
Referring to fig. 8, after the device is placed on the component, the component detects the weight in step S801.
That is, the accessory detection device gives the weight to the accessory after the tablet or phone is placed on the accessory. The detection is effected here, for example, by means of a pressure sensor.
In step S802, m seconds of average pressure < a is detected, and the device is determined to be absent, so that the accessory remains in the original operating state. That is, if the fitting detects m consecutive seconds, the average of the pressure values is less than a, and it is determined that the device is not present. I.e. no equipment is placed on the accessory.
In step S803, an average pressure of m seconds is detected between a and b.
At this time, the type of the device is confirmed to be a mobile phone, and the charging current of the accessory is set to be x.
In step S804, m seconds of average pressure > b is detected, it is confirmed that the device type is flat plate, and the charging current of the accessory is set to y.
Wherein m, a, b, x, y satisfy the relationship of m >0, b > a >0, x > y.
In order to prevent misoperation, for example, when the user places the accessory on a book that is not the device but is the same as the device in weight, in this embodiment, after the accessory determines the device type, step S805 is executed, and the accessory sends out a wireless signal to inquire the device, for example, a wireless charging transmitting circuit of the accessory sends out a wireless signal to inquire the device.
If the device responds, i.e., gets a confirmation signal, steps S806 and S807 are performed,
step S806, the accessory starts wireless charging of the device,
step S80, the accessory and the device are bluetooth paired. The appointed application installed on the mobile phone can output a prompt page to the user, so that the user can choose to forbid the Bluetooth from being opened and forbid the pairing.
If the device does not respond, i.e., does not receive an acknowledgement signal, the accessory will not begin wirelessly charging the device; that is, wireless charging is not performed. At this time, the accessory can be charged by a contact method (the charging interface of the accessory contacts the terminal of the device).
It can be appreciated that after the device and accessory bluetooth are paired, information of the accessory, such as current remaining power information, is displayed on the device, alerting the user whether the accessory needs to be charged.
The pick-up and play functions of the device may also be switched to the accessory. At this time, the user adds command words to the accessory calling keywords to search network data, inquire equipment information, dial and answer calls and play music, and realize function switching.
Referring to fig. 9, step S901 is performed, the device is removed from the accessory, and the accessory detects the weight.
That is, when the cell phone or tablet is removed from the accessory, the accessory will detect the weight imparted to the accessory by the pressure sensor.
Step S902, detecting that the average pressure < a is m seconds, the device is determined to be absent, and the accessory stops wirelessly charging the device and prompts the user through the device whether to maintain the wireless connection. That is, the bluetooth connection and handover situation between the device and the accessory depends on the user's settings in the handset APP in advance.
Step S903, acquiring the switching information of the immediate disconnection,
for example, when the device APP is set to disconnect immediately, the accessory interrupts the connection with the device, the accessory enters a standby state, and the pickup and play functions switch back to the device.
Step S904, acquiring the handover information of the connection maintenance,
for example, when the device APP is set to maintain connection, the accessory and the device continue to be connected, that is, keep the original bluetooth connection and function switching state.
Step S911 is performed during the process of maintaining the connection, and the accessory issues a wireless signal to interrogate the device.
Here, the accessory determines whether the device triggered a connection interruption event. Step S912, the device is making a turn, the acceleration data of the device > k and the distance < j;
when the device is making (or making or receiving) a call, which causes a change in the acceleration data, then by detecting the acceleration and proximity of the device, when the device acceleration > k and the distance < j, this event is known and the pick-up and play functions are automatically switched back to the device. The distance here is a distance at which the mobile phone is close to the face of the user, for example, less than 10 mm. Wherein k >0, j > 0.
In practical application, after the call is completed, the accessory can switch the pickup and play functions to the accessory end again according to the acquired trigger information of the call completion.
In step S913, the device is at rest and held for d minutes. The device is in a static state, i.e. the acceleration is 0, then after d minutes, the connection is interrupted, the accessory automatically enters a standby state, and the functions of sound pickup and playing are switched back to the mobile phone end. In the embodiment, the switching is performed after the mobile phone is in the static state for d minutes instead of immediately, so that the switching accuracy is improved, and the influence on the user experience caused by switching back and forth is avoided.
Step S914, the user shakes the device w times, and each time the device acceleration > k, the user may also set in advance that the user shakes the device w times through the APP on the mobile phone, and the device acceleration > k controls the connection to be interrupted each time. The accessory will automatically go to standby according to this information acquired and switch the pick-up and play function back to the device. Here, w is, for example, 3, so that when the user shakes the mobile phone 3 times, the acceleration data of each time is greater than k, the effect of switching the sound pickup and playing functions back to the mobile phone can be achieved, and the mobile phone switching method is simple and convenient to operate and high in flexibility.
Step S915, the device is brought i meters away from the accessory,
for example, detection of acceleration and distance of the device, the accessory will interrupt the bluetooth connection to the device based on this information after n (say 15 minutes) minutes of being brought i meters (say 2 meters) away from the accessory. At this time, the accessory automatically enters a standby state and switches the pickup and play functions back to the device; here, i >0, n > 0.
It should be noted that the execution order between step S911 and step S915 is not strict, and may be a parallel relationship.
