Example one
Fig. 1 is a flowchart of a control method for an on-vehicle display device according to an embodiment of the present invention. The embodiment can be applied to automatic deflection control of the vehicle-mounted display equipment so as to meet the requirement of a user on display. The method can be executed by a control device of the vehicle-mounted display device, the control device of the vehicle-mounted display device can be realized in the form of hardware and software, and the control device of the vehicle-mounted display device can be integrated in a vehicle-mounted controller or an electronic device such as a vehicle. As shown in fig. 1, the method includes:
s110, receiving a control instruction for the display equipment, and analyzing rotation information in the control instruction, or identifying rotation related information corresponding to the control instruction.
The display device is arranged in the vehicle cabin, for example, the display device can be a display screen central control display screen, a rear row display screen and the like, and is used for displaying interactive information so as to realize information interaction with passengers in the vehicle. The control instruction can be any type of external control instruction for the vehicle-mounted display device, and the control instruction includes, but is not limited to, an audio playing instruction, an audio playing stopping instruction, a video playing instruction, a video switching instruction, a navigation instruction and the like from the control content dimension of the control instruction, and in the acquisition mode dimension of the control instruction, the control instruction includes, but is not limited to, a voice instruction, a touch instruction, a key instruction, a gesture instruction and the like.
It should be noted that, a hardware device for acquiring control instructions is integrated in the vehicle-mounted device to support input and acquisition of control instructions in different forms. Taking the voice command in the control command as an example, the voice command can be collected based on preset voice collecting equipment such as a microphone or a sound pickup, and the preset voice collecting equipment such as the microphone or the sound pickup is integrated in the vehicle-mounted system, so that when a person in the vehicle makes a sound, a sound signal is received by the voice collecting equipment such as the microphone or the sound pickup. Taking the control instruction as the gesture instruction as an example, the gesture instruction can be acquired based on preset image acquisition equipment such as a camera, and further, components such as a touch screen and a key can be integrated in the vehicle-mounted system to acquire the touch instruction and the key instruction. Furthermore, under the condition that the control instruction is in other input modes, the vehicle-mounted equipment can be correspondingly integrated with a collecting component.
Optionally, the control instruction includes a rotation control instruction and a non-rotation control instruction. The rotation control instruction and the non-rotation control instruction may be input through a key operation, a touch operation, a voice operation, a gesture operation, and the like, where the rotation control instruction is an instruction explicitly carrying rotation information in the instruction, where the rotation information may include but is not limited to a deflection direction and/or a deflection angle, and for example, the rotation control instruction may be a voice instruction whose content is "turn left", may be a key instruction formed by clicking a left turn button, and may also be an instruction formed by a left turn gesture, and the like, which is not limited thereto. The non-rotation control command is a command in which rotation information is not included in the command, and the non-rotation control command is a command for controlling an arbitrary member or application other than the rotating member. Illustratively, the non-rotational control instructions may include, but are not limited to, voice control instructions, video control instructions, navigation control instructions, call control instructions, and the like.
In this embodiment, when a control command is detected, rotation information related to the control command is identified. In some embodiments, the control command is a rotation control command, and the rotation information in the control command is parsed. The rotation control instruction can be input in different forms, and correspondingly, the corresponding analysis rule is called according to the input type of the rotation control instruction, and the input rotation control instruction is analyzed to obtain the rotation information in the rotation control instruction. For example, taking the rotation control instruction as the gesture instruction as an example, the collected gesture may be matched with a plurality of gestures stored in advance, and the rotation information corresponding to the gesture successfully matched is determined as the rotation information in the input rotation control instruction. For example, taking a rotation control instruction as a voice instruction as an example, the rotation control instruction is converted into text information, a keyword in the text information is identified, a rotation-related keyword is determined, and the rotation information is determined based on the rotation-related keyword, wherein the rotation-related keyword may include a direction keyword and/or an angle keyword.
In some embodiments, the control command is a non-rotation control command, and rotation-related information corresponding to the control command is identified. The rotation related information is related information capable of representing rotation information, and optionally, the rotation related information corresponding to the control instruction includes but is not limited to: the command issuer controls one or more items of the content output by the display device. The command issuer may be any person in the vehicle, such as a main driver, a co-driver, and the like. The display device outputs content that is presented by the display device, which may include, but is not limited to, music, games, movies, navigation information, and the like, for example. The display device output content may be determined according to the application in the running state. And calling an identification rule of corresponding rotation related information according to the input type of the non-rotation control instruction so as to identify the non-rotation control instruction in any form to obtain the rotation related information. Illustratively, taking the non-rotation control instruction as a touch instruction, a key instruction and a gesture instruction as an example, a camera may be used to collect images or videos in the vehicle, and a person who implements the touch instruction, the case instruction and the gesture instruction is determined according to the collected images or videos to be used as an instruction sender. Taking the non-rotation control command as a voice command as an example, the position direction of the command sender is determined by recognizing the voice direction, and the command sender is further determined, for example, the voice direction of the non-rotation control command can be recognized by a matrix microphone array.
In the embodiment, the rotation associated information is identified through the non-rotation control instruction, the rotation of the display equipment can be controlled without inputting a rotation instruction by an operator, and the control mode of the display equipment is simplified.
And S120, determining a display object of the display equipment based on the rotation information or the rotation related information.
The display object refers to a main display object of contents displayed by the display device in the vehicle, wherein the display object may be any person in the vehicle, such as a main driver, a co-driver, a rear-row passenger, and the like. According to the requirements of the user, the vehicle-mounted display equipment is displayed to the user at a relatively accurate visual angle.
Since a plurality of passengers may be included in the vehicle, the content displayed on the display device may be displayed to one or more users, for example, for the navigation display interface, the main display object may be a main driver, so that the main driver can refer to the navigation information of the navigation display interface to avoid a wrong driving route. For example, for entertainment display interfaces such as video and music, the main display object can be a passenger or a rear passenger. In this embodiment, by determining the display object of the display device, the display device is conveniently subjected to targeted deflection, so that the display interface of the display device faces the display object, and a good information display angle is provided for the display object.
The presentation object of the display device may be determined based on the rotation information or the rotation-related information. When a rotation instruction is received, analyzing according to the rotation instruction analyzing process, and determining a display object according to a preset program based on rotation information obtained through analysis. Specifically, the display object may be determined by the rotation direction and/or the rotation angle in the rotation information. Optionally, the person in the vehicle in the space range corresponding to the rotation direction is determined as the display object. For example, taking the rotation information as an example of being resolved through a gesture, the gesture instruction resolving process resolves that the rotation information is "turn right", which may be that a person on the right side is determined as a display object. For example, a preset program may be set to "turn right command" corresponding to "passenger position", and in this case, the display object may be determined to be "passenger". For example, taking the rotation information as an example of parsing through voice, the voice instruction parsing process parses the voice information as "turn left", which may be to determine a person on the left side as the display object. The "instruction to turn left" corresponding to the "main driving position" may be set in a preset program, and at this time, the display object is determined to be the "main driver". Optionally, the corresponding space range after rotation is predicted through the rotation direction and the rotation angle, and the people in the vehicle in the space range are determined as the display object. Illustratively, the current angle of the display device is 30 ° on the left side, the rotation instruction in the rotation information is to turn right, the rotation angle is 30 °, accordingly, the orientation of the display device after rotation can be predicted to be towards the rear of the vehicle, the corresponding spatial range of the display device can be the middle part and the rear part of the vehicle, and the person in the rear row of the vehicle can be determined as the display object when the person in the rear row of the vehicle is located in the spatial range.
And when a non-rotation instruction is received, identifying according to the rotation related information identification process, and determining the display object according to a preset program based on the identified rotation information. The rotation correlation information comprises one or more items of output contents of the instruction issuer and the display device, and correspondingly, the display object can be determined according to the one or more items of output contents of the instruction issuer and the display device.
In some embodiments, determining the presentation object of the display device based on the rotation correlation information includes: and determining the command sender as a display object of the display device, and optionally determining the display object according to the sitting position or the direction of the command sender. For example, taking the rotation-related information through voice information recognition as an example, the position of the voice speaker is recognized through the voice information recognition process, and may be the main driving position, that is, the display object is "the main driver".
In some embodiments, determining the presentation object of the display device based on the rotation correlation information includes: and controlling the display equipment to output content based on the control instruction, and determining the display object of the display equipment according to the display content types corresponding to different display objects.
The display device outputs content including, but not limited to, audiovisual information, gaming information, navigation information, and the like. The display contents corresponding to different display objects generally refer to determining the display objects according to the display contents. Optionally, the corresponding relationship of the display content types of the display object may be preset, where the display content types may include a driving type, an entertainment type, and the like, for example, navigation information belongs to the driving type, and music, video, games, and the like belong to the entertainment type. In the preset corresponding relation of the display content types of the display objects, a main driver can correspond to the driving type, and a copilot and a rear-row passenger can correspond to the entertainment type. For example, taking the display content as the navigation information, the display content type of the display device is determined as the driving type, and then the main driver is determined as the display object.
Correspondingly, the command issuer and the output content of the display device jointly determine the display object: and determining a display object by recognizing information such as voice, touch, key, gesture and the like of the command sender, and determining the display object of the display equipment by recognizing output content of the display equipment.
The common determination of the display object based on the instruction issuer and the output content of the display device may be a determination of a first display object based on the instruction issuer and a determination of a second display object based on the output content of the display device, respectively, and the first display object and the second display object may be the same or different. And determining the same display object as a final display object under the condition that the first display object and the second display object are the same. And under the condition that the display objects respectively determined by the instruction issuer and the control instruction for controlling the display equipment to output the contents are different, determining the display object of the display equipment based on the priority of the instruction issuer and the control instruction for controlling the display equipment to output the contents.
The priority of the command issuer and the priority of the output content of the display device are different, and can be set according to the setting requirement of the user, for example, the priority of the command issuer can be preset to be higher, and the priority of the control command for controlling the output content of the display device to be higher can also be preset. And determining a display object of the display equipment based on the rotation association information with the highest priority. For example, taking the case that the position of the command issuer is recognized as the co-driver position and the display device outputs the navigation information at the same time, if the command issuer is recognized as the co-driver according to the voice command, the co-driver is determined to be the display object of the display device, whereas if the command issuer is recognized as the navigation information according to the display device, the main driver is determined to be the display object of the display device. The display objects determined by the two are different, the priority of the command issuer can be set to be higher, and at the moment, the copilot is determined to be the display object. On the contrary, the priority of the output information of the display device can be set to be higher, and at the moment, the main driver is determined to be the display object.
S130, controlling the display device to rotate based on the display object so that a display interface of the display device faces the display object.
And after the display object is determined, identifying the visual angle position of the display object, and determining the rotation angle so that the display equipment meets the visual angle requirement of the display object.
The visual angle position of the display object can be detected by installing a position angle sensor on the display equipment, the angle required to rotate is obtained according to the detection result, and the display equipment is controlled to rotate according to the rotation angle obtained by detection according to a preset program. For example, the main driver is taken as a display object, the current display device interface is vertical to the vehicle body, the state can be set as an initial state, the left 40 degrees of the main driving visual angle in the vertical direction of the display device is detected through an azimuth angle sensor on the display device, at the moment, the display device is controlled to rotate left 40 degrees according to a preset program, and the display device interface is made to be vertical to the main driving visual line.
In some embodiments, the different display objects may respectively correspond to different display angles, the display angles of the display objects are read, and the display device is controlled to rotate based on the display angles.
The rotation executing structure of the display device may be implemented in any mechanical structure, for example, the rotation executing structure includes, but is not limited to, a multi-link structure, a rack and pinion structure, a gear and pinion structure, a worm structure, a lead screw structure, and the like. The screen angle is not fixed, and the screen can be inclined left and right within a certain angle range.
In some embodiments, after controlling the display device to rotate based on the presentation object, the method further comprises: and determining the sight direction of the display object in real time, and controlling the display equipment to carry out follow-up display based on the display object. For example, the display object can be eye-tracked, and the display device can be controlled to follow the display based on the eye-tracking result, so that a good viewing angle can be provided for the display object.
On the basis of the above embodiment, the method further includes: in the display process of the display equipment, if any object is detected to be in a watching state on the display equipment, the object is determined as a display object, and the display equipment is controlled to rotate.
And determining that the user is in a watching state on the display equipment when the duration of the sight line of any user staying on the display equipment exceeds a threshold value. The method comprises the steps of installing an eye tracker in a vehicle, carrying out sight line detection by tracking the movement track of eyeballs, and determining the sight line to be in a watching state when the sight line is detected to stay on a display device and stay for a certain time, for example, the stay time can be set to be more than 3 seconds. For example, when the eye tracker tracks that the sight line of the rear passenger stays on the display device and keeps above a preset watching time, the display device is determined as a watching state, and at this time, the rear passenger is determined as a display object, and the display device is controlled to rotate so that the interface of the display device faces to the rear passenger.
In some embodiments, when it is detected that a person other than the current display object is in a watching state on the display device, it is determined whether the current display object is in the watching state on the display device, if so, the display object is not switched, and if not, the display object is switched and the display device is controlled to rotate. By judging the watching state of the person in the vehicle on the display device, the display device can be conveniently rotated in time, so that the display content can be displayed to the person concerned at present, and the flexibility and the adaptability of the display device are improved.
According to the technical scheme, the display object of the display equipment is determined by identifying the rotation information and the rotation associated information corresponding to the control command, and the display equipment is actively adjusted to the relatively optimal posture according to the determined display object. The vehicle-mounted display equipment can be adaptively and actively matched with the operation of personnel in the vehicle, so that the display equipment and the display performance are exerted, and the optimal man-machine position is provided.
