Fig. 1 schematically shows an application scenario of a method for prompting information according to an embodiment of the present application.

As shown in fig. 1, the method for prompting information according to the embodiment of the present application may be used in a vehicle driving scenario, for example, and the method may be executed by an on-board processor as a part of an on-board system. The vehicle-mounted multimedia device may refer to, for example, a vehicle-mounted multimedia button 101, the vehicle-mounted multimedia button 101 may be disposed on a control panel or a steering wheel of a vehicle, and a user may regulate and control audio data through the vehicle-mounted multimedia button 101, for example, may regulate volume or playing progress of the audio data, switch the audio data, and the like. The vehicle-mounted multimedia keys 101 in the embodiment of the present application are physical keys, and the vehicle-mounted multimedia keys 101 may include push type operation keys and knob type operation keys.

The car audio data may come from a variety of sources, such as online music like QQ music, FM/AM radio, online radio, bluetooth music, USB music, etc. After the music is played in the car for a while, the user may forget which sound source he selected before, and in the case where the sound source is unclear, an erroneous command may be issued or the system may not respond when the in-vehicle multimedia key 101 is operated. For example, if the user thinks that the currently played sound source is online music, the user wants to switch to the next music through pressing a key, but if the currently played sound source is FM/AM radio, the user may perform a channel searching operation, which may affect the user experience. For another example, the user would like to press the enter key long enough to fast forward the current audio, but the system is unresponsive and cannot perform fast forward operations, which may be due to the user forgetting that bluetooth music is currently being played in the vehicle and the handset providing the music does not support fast forward operations.

Therefore, the embodiment of the application provides a method for prompting information, when a user triggers the vehicle-mounted multimedia key 101, the prompt information can be sent out, and for example, the prompt information can be output through the central control screen 102. The prompt information contains sound source information corresponding to the currently played audio data, and prompts which sound source is currently used by the user, so that the user can judge whether the current sound source is an object which the user expects to control, and the user can timely receive feedback and correct, and execution of wrong instructions is avoided.

An embodiment of the present application provides a method for prompting information, and the method for prompting information according to an exemplary embodiment of the present application is described below with reference to fig. 2 to 6 in conjunction with an application scenario of fig. 1.

Fig. 2 schematically shows a flow chart of a method of prompting for information according to an embodiment of the present application.

As shown in fig. 2, the method 200 for prompting information according to the embodiment of the present application may include operations S210 to S240, for example.

In operation S210, in response to receiving a first event generated as the in-vehicle multimedia device is operated, it is determined whether the first event is a predetermined event.

In operation S220, in case that it is determined that the first event is a predetermined event, at least current sound source information of currently played audio data is acquired.

In operation S230, a prompt message including current sound source information is generated.

In operation S240, the presentation information is output using the in-vehicle output device.

In the embodiment of the application, the vehicle-mounted multimedia device may refer to, for example, a vehicle-mounted multimedia key, and when a user operates the vehicle-mounted multimedia key, the vehicle-mounted system may generate an operation event according to a key type and a mode of operating the key by the user, specifically, a correspondence between the event and the key type and the key operation mode may be determined according to an actual situation, for example, if the user clicks a play key, an event for playing audio may be correspondingly generated, if the user presses the play key for a long time, an event for fast forwarding a current audio may be correspondingly generated, if the user rotates a volume knob clockwise, an event for increasing a volume may be correspondingly generated, and the like.

After a first event generated by a user operating a vehicle-mounted multimedia key is obtained at a certain moment, whether the first event is a predetermined event or not may be determined, and if the first event is the predetermined event, current sound source information corresponding to currently played audio data may be obtained. The audio source information may refer to source information of currently played audio data, and if the currently played audio data is provided by online music software, the audio source information may be marked as a name or an icon of the online music software. If the currently played audio data is provided by a broadcasting station, the sound source information may be marked as "FM/AM broadcast" or a corresponding icon. If the currently played audio data is provided by the USB storage medium, the sound source information may be marked as "USB audio" or a corresponding icon. If the currently played audio data is provided by the mobile phone through bluetooth, the sound source information may be marked as "bluetooth music" or a corresponding icon. For example, when a song s1 is currently being played using the online music software a1, the song s1 is currently played audio data, and the song source corresponding to the song s1 is the online music software a1, the name a1 of the online music software a1 or an icon of the software may be used as current sound source information.

After the current sound source information is obtained, prompt information about the current sound source information may be generated and output by the in-vehicle output device.

According to the embodiment of the application, when the user triggers the vehicle-mounted multimedia key to generate the predetermined event, the vehicle-mounted output device can send the prompt information, the prompt information comprises the sound source information corresponding to the currently played audio data, and the user is prompted about which sound source is currently used, so that the user can judge whether the current sound source is the object which the user desires to control, and the user can timely receive feedback and correct, and execution of error instructions is avoided.

According to an embodiment of the application, the predetermined event comprises: an adjustment operation for the currently played audio data and a switching operation for the audio data in the current sound source. The adjusting operation comprises at least one of pause, play, fast forward, reverse, volume up and volume down. The switching operation includes at least one of switching to the previous audio data and switching to the next audio data.

In the embodiment of the application, the predetermined event is used for adjusting the audio data in the current sound source, including performing volume adjustment, fast forward, pause and other adjustment operations on the audio currently playing in the current sound source, and switching the audio data currently playing to another audio data in the current sound source, for example, a song s1 currently playing in the online music software a1, and switching the song s1 to a next song s2 in the online music software a 1.

According to the embodiment of the application, an event which is easy to cause misoperation or cause no response of the system is set as a predetermined event, and when a user triggers the event, prompt information can be sent out.

According to the embodiment of the application, the prompt information output by the vehicle-mounted output device comprises at least one of the following modes: displaying prompt information by using a central control screen; displaying prompt information by using an instrument panel; and outputting prompt information by utilizing the voice of the vehicle-mounted sound box.

Fig. 3A schematically shows a schematic diagram of a user operating an in-vehicle multimedia key according to an embodiment of the application.

Fig. 3B schematically illustrates a schematic diagram of displaying a prompt message by using a central control screen according to an embodiment of the present application.

As shown in fig. 3A and 3B, when the user turns on the navigation function during the music playing, the center control screen 302 starts displaying the navigation map 303 while the car speaker continues to output music. If the user wants to switch to the next song through the switch key 301 at a certain time, after obtaining an event of switching to the next audio data, a pop-up box 304 may be popped up through the center screen 302, and the current sound source information a1 is displayed in the pop-up box 304. The bullet box 304 may disappear after displaying for several seconds (e.g., 2s) to avoid impact on other displayed content (e.g., a navigation map).

In the embodiment of the application, after the first event is received, whether the current central control screen displays an audio playing interface or not can be judged, and the current sound source information is acquired and prompt information is sent out under the condition that the audio playing interface is not displayed on the current screen. Or, the current sound source information can be directly acquired and prompt information can be sent without judging whether the current central control screen displays an audio playing interface.

In another embodiment of the present application, a display panel may be disposed in a dashboard area of a vehicle, and after receiving a predetermined event, a pop-up box may be popped up in the display panel in the dashboard area and a prompt message may be displayed in the pop-up box. The instrument panel is positioned in front of the user, and the prompt information is displayed in the area of the instrument panel, so that the user can check the prompt information more conveniently.

In another embodiment of the application, the prompt message can be output to the user through the vehicle-mounted sound box in a voice mode. The voice output mode can lead the user to drive the vehicle more attentively, and improve the safety.

In the embodiment of the application, a sound source switching key may be further disposed in the vehicle, for example, the sound source switching key may be disposed on a steering wheel or a control panel, and if the user finds that the current sound source is not the object that the user wants to operate and wants to replace the sound source, the user may switch to another sound source through the sound source switching key.

According to an embodiment of the present application, in a case that it is determined that the first event is a predetermined event, acquiring at least current sound source information of currently played audio data includes: if the first event is the adjustment operation aiming at the currently played audio data, acquiring the current sound source information and the detail information of the currently played audio data; and if the first event is a switching operation aiming at the audio data in the current sound source, acquiring the current sound source information and the detail information of the other audio data to be switched. Wherein the prompt message further comprises the detail information of the currently played audio data or the detail information of another audio data.

FIG. 4 schematically shows a flow chart of a method of prompting for information according to another embodiment of the present application.

Fig. 5 schematically shows a schematic diagram of displaying a prompt message according to another embodiment of the present application.

Fig. 6 schematically shows a schematic diagram of displaying a prompt message according to yet another embodiment of the present application.

As shown in fig. 4, 5 and 6, a first event generated by a user operating the in-vehicle multimedia key is received (operation S410), it is determined whether the first event is a predetermined event (operation S420), and if the first event is a predetermined event, it is determined which event of the predetermined events the first event belongs to, i.e., it is determined whether the first event belongs to an adjustment operation for currently played audio data or a switching operation for audio data in a current sound source (operation S430).

If the first event is an adjustment operation such as volume adjustment and fast forward for the currently played audio data, in addition to the current sound source information a1, the detailed information of the currently played audio data may be obtained (operation S441), where the detailed information may include information such as the name S1 of the currently played song, and the singer g 1. Prompt information is then generated from the current sound source information and the detail information of the currently played audio data (operation S451), and the prompt information 504 is output using the in-vehicle output device (operation S461).

If the first event is an operation of switching the currently played audio data to the next audio data in the current audio source, the current audio source information and the detail information of the next audio data may be acquired (operation S442), where the detail information may include information such as the name S2 of the next song, the singer g2, and the like. Then, prompt information is generated based on the current sound source information and the detailed information of the next audio data (operation S452), and the prompt information 604 is output using the in-vehicle output device (operation S462).

In embodiments of the present application, as each audio software begins to play audio, its source category may be sent to the system to cause the system to record which audio software is currently playing. Upon receiving the first event, it may be determined from information recorded by the system which audio software is currently being played. After the System obtains the first event, the System may send the first event to the currently played audio software, so that the currently played audio software feeds back the sound source information and the detailed audio information to the System after receiving the first event, and specifically, the audio software may call a System UI interface of the System to feed back the sound source information and the detailed audio information to the System.

According to the embodiment of the application, besides the current sound source information, the detail information of the current audio or the detail information of another audio to be switched to can be output, so that the user can further clearly and specifically determine the song information and judge whether the song is the object which the user wants to operate.

According to an embodiment of the present application, the method for prompting information may further include: if the first event is a switching operation for the audio data in the current sound source, executing the following operations: within a first preset time after the prompt message is output, if the first event is received again or a second event opposite to the first event is received, updating the prompt message; and within a first preset time after the prompt message is output, if the first event is not received again and the second event is not received, executing the operation corresponding to the first event. The first predetermined time period may be, for example, less than the time period for outputting the prompt message, for example, less than 3 s.

For example, in response to receiving an event of switching to the next audio data, a prompt message including current sound source information and detail information of the next audio data may be displayed on the screen. If the instruction for switching to the next audio data is not received again and the instruction for switching to the previous audio data is not received within the first preset time, the user is considered to play the next audio data by default, and the next audio data can be played. If the user finds that the next audio data is not to be played after checking the prompt information, the user can press the key switched to the next key again before the prompt information is not finished, the prompt information can be updated to the detail information of the next audio data, and the user is considered to default to play the audio data in the current prompt information until the instruction is not received again within the first preset time after the prompt information is updated.

According to the embodiment of the application, for the event of switching the audio, after the audio source and the next audio information are output, whether the event is switched is determined according to the feedback condition of the user, and the audio in the prompt message is updated after the user presses the first key or the last key again. Based on the method, switching operation can be performed according to the user intention, and the user experience is improved.

According to an embodiment of the present application, the method for prompting information may further include: and if the first event is the adjustment operation aiming at the currently played audio data, responding to the received first event, and executing the operation corresponding to the first event.

For example, after receiving a volume up event, a prompt message may be displayed on the screen and an operation of turning up the volume of the current audio may be performed at the same time. For another example, after receiving a fast forward event, a prompt message may be displayed on the screen and an operation to fast forward the current audio may be performed at the same time.

According to the embodiment of the application, for the adjustment event of the current audio frequency, such as volume adjustment, fast forward and the like, corresponding operation can be immediately executed when the adjustment event is received. Based on the method, the instructions with high requirements on timeliness can be ensured to be executed quickly.

According to another embodiment of the present application, the method for prompting information may further include: in response to receiving the first event, an operation corresponding to the first event is performed.

After receiving the first event, an operation corresponding to the first event may be executed immediately. For example, upon receiving an event to switch to the next, a prompt message may be displayed on the screen and the next audio data may be played simultaneously. For another example, after receiving the volume-up event, a prompt message may be displayed on the screen and an operation of turning up the volume of the current audio may be performed at the same time.

According to the embodiment of the application, the execution is carried out immediately after the event is received, and the timeliness of the instruction response can be ensured. When the instruction is executed, the prompt information is output, and the prompt function can be achieved.

According to an embodiment of the present application, generating the prompt information may further include: generating prompt information under the condition that the current sound source information is different from the sound source information included in the prompt information output last time; or generating the prompt message under the condition that the interval between the receiving time of the first event and the time of outputting the prompt message last time exceeds a second preset time length. The second predetermined time period may be, for example, between 2 and 10 minutes.

For example, it is considered that the user can remember the current sound source information within the second predetermined time period after the previous prompt information is output, and therefore, if the predetermined event is received again within this time period, the prompt may not be performed, and the operation corresponding to the predetermined event may be directly performed.

For another example, if the user is reminded once during the use of the current sound source, if the predetermined event is received again, the prompt may not be performed, and the operation corresponding to the predetermined event may be directly executed.

According to the embodiment of the application, the prompt is triggered once again every preset time or after the sound source is switched, so that the condition that the prompt is too frequent and the user is not disturbed excessively can be avoided.
