[0057] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0058] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.

[0059] Figure 1 This is a schematic diagram illustrating the main steps of a vehicle-mounted display device control method according to an embodiment of the present invention. Figure 1 As shown, the vehicle-mounted display device control method of this embodiment mainly includes the following steps S101 to S102:

[0060] Step S101: In response to the video playback on the in-vehicle display device, obtain the gaze of each viewer;

[0061] When people inside the vehicle are watching videos played on the in-vehicle display, images inside the vehicle can be captured by image acquisition devices pre-configured in the cabin. By analyzing these images, the people watching the video inside the vehicle can be identified.

[0062] Furthermore, the in-vehicle display equipment can include a central control display, a front passenger display, and / or rear-seat display. Each in-vehicle display can be used by people in different seats to watch videos. For example, the central control display and the front passenger display can be used by the driver and front passenger, as well as by passengers in the rear seats; the rear-seat display can be used by all passengers in the rear seats. Therefore, it is necessary to determine the corresponding viewers for each different in-vehicle display device.

[0063] It should be noted that when the in-vehicle display device playing the video is a central control display device or a passenger-side display device, the vehicle's speed can be further obtained. When the vehicle's speed is not 0, the vehicle may be in motion, that is, the driver may be performing driving operations. In this case, the viewer may not include the driver.

[0064] Furthermore, when multiple in-vehicle display devices are present in the vehicle, different display devices can play videos in unison based on the operation commands of at least one viewer. During this synchronized playback, the viewer can control the multiple display devices playing in unison by sending operation commands to any one of them. For example, when a central control display, a passenger-side display, and a rear-seat display are present in the vehicle, and the viewer includes the driver and rear-seat passengers, the rear-seat passengers can send an operation command to the rear-seat display to synchronize playback across all devices. Based on this operation command, the central control display, passenger-side display, and rear-seat display can simultaneously play the same video. While watching the video, the driver can send an operation command to the central control display to pause playback, and based on this operation command, the central control display, passenger-side display, and rear-seat display can simultaneously pause video playback.

[0065] The gaze of moviegoers is tracked by eye-tracking devices pre-configured within the vehicle cabin to determine the gaze of each viewer. These eye-tracking devices can be based on image acquisition systems, sensors, or a combination of both. Essentially, any device capable of tracking and determining the gaze of people within the vehicle cabin can be used; no specific limitations are imposed here.

[0066] Optionally, the image acquisition device and the eye-tracking device can be installed at any location within the vehicle cabin to acquire images and the gazes of all occupants. Furthermore, multiple image acquisition devices and eye-tracking devices can be configured to avoid situations where a single image acquisition device cannot capture images of all occupants or a single eye-tracking device cannot capture their gazes. As an example, the in-cabin image acquisition device or in-cabin eye-tracking device can be installed near the rearview mirror, A-pillar, central control display, the center of the roof, near the front trim panel, near the B-pillar, and / or next to the rear display, but is not limited to these locations.

[0067] Step S102: Control the video played on the vehicle display device according to the viewer's line of sight.

[0068] Once the line of sight for each viewer is determined, the video played on the in-vehicle display can be controlled based on the position of each viewer's line of sight.

[0069] According to the vehicle-mounted display device control method of the present invention, when the vehicle-mounted display device is playing a video, the eye position of each viewer is determined, and the video being played is controlled based on this. This eliminates the need for viewer to perform touch, voice, or gesture operations. The viewer's need to control the video being played can be identified simply by their eye position, which improves the ease of operation for the viewer, realizes a seamless video interaction method for the viewer, and enhances the viewing experience.

[0070] In one optional embodiment, controlling the video played on the in-vehicle display device according to the viewer's line of sight includes:

[0071] In response to the viewer's gaze falling outside the playback area of ​​the video on the in-vehicle display device, the video playback is paused.

[0072] Understandably, when there are one or more viewers in the vehicle cabin, the system can directly identify whether their attention is on the video by observing the position of their gaze. When all viewers' eyes are on the video playback area of ​​the in-vehicle display, it can be determined that their attention is focused on watching the video, and the in-vehicle display continues playing. When all viewers' eyes are on the video playback area of ​​the in-vehicle display, it can be determined that all viewers' attention has shifted and they are not currently focused on watching the video. To prevent viewers from missing any video content when their attention returns, the video can be paused.

[0073] In one optional embodiment, controlling the video played on the in-vehicle display device according to the viewer's line of sight includes:

[0074] In response to the fact that some of the viewers' gaze falls outside the playback area of ​​the video on the in-vehicle display device, a first operation prompt is displayed on the in-vehicle display device; in response to the operation result of any of the viewers on the first operation prompt, the video is controlled.

[0075] Specifically, the system identifies whether each viewer's attention is focused on watching the video based on the position of their gaze.

[0076] When all viewers' eyes are focused on the video playback area on the in-vehicle display device, it can be confirmed that all viewers' attention is concentrated on watching the video, and the in-vehicle display device can be controlled to play the video.

[0077] When all viewers' gazes are focused outside the video playback area on the in-vehicle display device, it can be determined that none of the viewers' attention is on watching the video, and the in-vehicle display device should be controlled to pause video playback.

[0078] When at least one viewer's gaze falls anywhere outside the video playback area on the in-vehicle display device, it can be determined that at least one viewer's attention is not focused on watching the video, while the attention of other viewers remains focused. To cater to the needs of all viewers, a first operation prompt can be displayed on the in-vehicle display device, and it can be identified whether any viewer has acted upon the first operation prompt. Upon identifying the action result of any viewer responding to the first operation prompt, the video can be controlled based on the result. The first operation prompt can float within or outside the video playback area, and its transparency can be high or adjustable to avoid obscuring the video content. For example, such as... Figure 2 As shown, in the vehicle display device 100, when playing video in a non-full-screen format, the video playback area 200 does not occupy the entire screen of the vehicle display device 100. The first operation prompt 310 can be located below the playback area, without obstructing the view of the playback area 200. Figure 3 As shown, in the vehicle display device 100, the video is played in full screen, and the video playback area 200 occupies the entire screen of the vehicle display device 100. The first operation prompt 310 can be located in the lower part of the playback area, with a certain degree of transparency, so as not to completely block the screen of the playback area 200.

[0079] Furthermore, a first display timer can be started simultaneously with the first operation prompt. If, when the first display timer reaches a preset first display time threshold, at least one viewer's gaze remains outside the video playback area on the in-vehicle display device, and no viewer is detected to have performed any operation on the first operation prompt, the first operation prompt is stopped from being displayed to avoid its continued display affecting the viewer's viewing experience. If, when the first display timer has not reached the preset first display time threshold, any viewer is detected to have performed an operation on the first operation prompt, the video is controlled based on the operation result. If, when the first display timer has not reached the preset first display time threshold, the gaze of a viewer who previously had their gaze outside the video playback area on the in-vehicle display device returns to the playback area, then all viewers' gazes are now within the video playback area on the in-vehicle display device, the first operation prompt is stopped from being displayed, and the video playback continues.

[0080] In one alternative embodiment, the first operation prompt mentioned above includes continuing playback;

[0081] Before displaying the first operation prompt on the aforementioned in-vehicle display device, the method further includes:

[0082] The above video will pause playback.

[0083] The above-mentioned response to the operation result of any of the above-mentioned viewers on the above-mentioned first operation prompt, controlling the above-mentioned video, includes:

[0084] In response to any of the aforementioned viewers selecting "continue playback" in the first operation prompt, control the video to continue playing.

[0085] If the system detects that some viewers' gazes are outside the video playback area, it can pause the video playback according to a pre-set pause mode, thus preventing viewers whose gazes are outside the playback area from missing the video content. Simultaneously, a prompt to continue playback is displayed on the screen.

[0086] The first operation prompt can be a function bar with controls, or a pop-up window with questions and buttons, etc., without specific limitations. Since the video has automatically paused at this point, the first operation prompt can include a control to continue playback, so that viewers can control the video to continue playing after selecting the control in the first operation prompt that indicates continued playback.

[0087] Optionally, if the first operation prompt may also include other prompts, controls, and / or buttons, when the user's selection result for other prompts, controls, and / or buttons in the first operation prompt is detected, the video can be adjusted based on the function indicated by the other prompts, controls, and / or buttons.

[0088] In an optional embodiment, after controlling the video to continue playing, the method further includes: recording the video playback progress corresponding to the control of the video to continue playing; in response to detecting that some viewers' gazes have returned to the playback area of ​​the video on the vehicle display device, determining the missed video duration based on the video playback progress corresponding to the continued playback, and displaying a prompt message on whether to rewind and play the video segment corresponding to the missed video duration.

[0089] If any viewer selects "Continue Playing" in the first operation prompt, the video can be controlled to continue playing. However, since some viewers' eyes are outside the playback area, considering the video viewing needs of these viewers, the corresponding video playback progress when playback continues can be determined and recorded.

[0090] Once a viewer's gaze returns to the playback area, the system can determine the duration of the missed video by combining the recorded playback progress when the viewer resumed playback with the playback progress when the viewer's gaze returned. A prompt will then be displayed on the in-vehicle display asking whether the viewer wants to replay the video segment corresponding to the missed duration. If any viewer chooses to replay based on the prompt, the missed video segment will be replayed. If any viewer cancels the replay prompt, the prompt will stop displaying the replay prompt, and playback will resume according to the playback progress when the viewer's gaze returns to the playback area. As an example, if it is detected that any viewer selects "Continue Playing" in the first operation prompt, the video can be controlled to continue playing. At this time, the video playback progress is 9 minutes and 36 seconds. When the viewer's gaze returns to the playback area, the video playback progress is 12 minutes and 40 seconds. It can be determined that 3 minutes and 4 seconds of the video duration was missed between 9 minutes and 36 seconds and 12 minutes and 40 seconds. A prompt message is displayed on the vehicle display device asking whether to rewind and play the corresponding video segment between 9 minutes and 36 seconds and 12 minutes and 40 seconds.

[0091] Furthermore, after controlling the video to continue playing as described above, the method further includes:

[0092] In response to the first operation prompt being displayed more times than the preset display threshold, the video is controlled to continue playing for each instance, and the corresponding video playback progress is recorded.

[0093] In response to the detection that some viewers’ gazes have returned to the playback area of ​​the video on the vehicle-mounted display device, the system determines the corresponding missed video duration for each video playback progress and displays a prompt message based on each missed video duration, asking whether to replay the video segment corresponding to the missed video duration.

[0094] Since there may be multiple viewers whose gaze is outside the playback area, or viewers' gaze may frequently move between the playback area and outside the playback area, to meet viewers' needs for watching video segments they missed, a preset display count threshold can be set. If the number of times the initial prompt is displayed exceeds the preset threshold, the corresponding video playback progress is determined each time playback continues. Similarly, the corresponding playback progress is determined each time viewers' gaze returns to the playback area. Therefore, based on the playback progress corresponding to each instance of continued playback and each instance of viewers' gaze returning to the playback area, several video segments corresponding to missed playback durations can be identified. For each missed playback duration, a prompt is displayed asking whether to replay the corresponding video segment, allowing viewers to choose the segment they wish to replay. Optionally, the preset display count threshold can be set according to actual conditions, for example, to 1 or 0.

[0095] As an example, the first time the video playback is controlled to continue, the corresponding playback time is 9 minutes and 36 seconds. When the viewer's gaze returns to the playback area for the first time, the video playback progress is 12 minutes and 40 seconds. Therefore, the first missed video segment is the 3 minutes and 4 seconds segment between 9 minutes and 36 seconds and 12 minutes and 40 seconds. The first time, a prompt message is displayed asking whether to rewind the 3 minutes and 4 seconds segment between 9 minutes and 36 seconds and 12 minutes and 40 seconds. The second time the video playback is controlled to continue, the corresponding playback time is 14 minutes and 2 seconds. When the viewer's gaze returns to the playback area for the second time, the video playback progress is 18 minutes and 32 seconds. Therefore, the second missed video segment is the 4 minutes and 30 seconds segment between 14 minutes and 2 seconds and 18 minutes and 32 seconds. The second time, a prompt message is displayed asking whether to rewind the 9 minutes and 36 seconds segment between 12 minutes and 36 seconds and 12 minutes and 40 seconds. The system displays a prompt message indicating whether to rewind to the video segment corresponding to 3 minutes and 4 seconds within the 40-second timeframe or the video segment corresponding to 4 minutes and 30 seconds within the 14-minute and 2-second timeframe (18 minutes and 32 seconds). The third time the video playback resumes, the corresponding playback time is 19 minutes and 53 seconds. When the viewer's gaze returns to the playback area for the third time, the video playback progress is 27 minutes and 58 seconds. Therefore, the video segment corresponding to the third missed video duration is the 8 minutes and 5 seconds segment between 19 minutes and 53 seconds and 27 minutes and 58 seconds. The system then displays a prompt message asking whether to rewind to the 3 minutes and 4 seconds segment between 9 minutes and 36 seconds and 12 minutes and 40 seconds, the 4 minutes and 30 seconds segment between 14 minutes and 2-18 minutes and 32 seconds, or the 8 minutes and 5 seconds segment between 19 minutes and 53 seconds and 27 minutes and 58 seconds, allowing the viewer to select the desired rewind segment.

[0096] In one alternative embodiment, the first operation prompt mentioned above includes pausing playback;

[0097] In response to the action result of any of the aforementioned viewers on the first operation prompt, control the aforementioned video, including:

[0098] In response to any of the aforementioned viewers selecting the first operation prompt indicating pause playback, the aforementioned video is paused.

[0099] If the system detects that some viewers' gazes are outside the video playback area, it can control the video to continue playing according to a pre-set playback mode, thus satisfying the viewing needs of viewers whose gazes remain within the playback area. Simultaneously, a prompt to pause playback is displayed on the screen, allowing viewers to decide whether to pause the video.

[0100] Optionally, the first operation prompt can be a function bar with controls, or a pop-up window with query statements and buttons, etc., without specific limitations. As an example, the first operation prompt can be as follows: Figure 2 and Figure 3 The first type of first operation prompt 310 shown or as follows Figure 4 The second type of first operation prompt 320 shown is a pop-up window that includes a question "Pause playback?" and "Yes" and "Cancel" buttons. The first type of first operation prompt 310 is a function bar that includes a variety of different function controls.

[0101] Furthermore, to facilitate viewers' control of other functions of the playing video, the first operation prompt may also include other prompts, controls, and / or buttons, such as controls indicating the playback of the previous video, controls indicating the playback of the next video, controls indicating brightness adjustment, and / or controls indicating volume adjustment, but not limited to these. As an example, when the first operation prompt is as follows... Figure 2 and Figure 3 When the first operation prompt 310 shown is displayed, it may include a control for pausing playback, a control for indicating playback of the previous video, a control for indicating playback of the next video, a control for indicating adjustment of screen brightness, and a control for indicating adjustment of volume.

[0102] Furthermore, if the first operation prompt also includes other prompts, controls, and / or buttons, the viewer's operation result in response to the first operation prompt may also include the operation result in response to the other prompts, controls, and / or buttons. For example, if the first operation prompt also includes a control indicating volume adjustment, the viewer can adjust the video volume according to their own needs using the control indicating volume adjustment.

[0103] In addition, the methods for viewers to operate in response to the aforementioned first operation prompt include, but are not limited to, touch operation, voice commands, and gesture operation. For example, when any viewer wishes to pause video playback, they can touch the pause control on the in-vehicle display screen to select pause playback, thereby controlling the video to pause; they can issue voice commands such as "pause playback," "stop playback," or "video pause," and through natural language recognition, identify voice commands indicating pause playback, signifying that the viewer has selected pause playback, thereby controlling the video to pause; or an image acquisition device can capture the viewer's image, and during image analysis, identify a pre-set gesture indicating pause playback, signifying that the viewer has selected pause playback, thereby controlling the video to pause.

[0104] In one optional embodiment, in response to receiving a command to pause video playback, it is determined whether the video is a live stream. If the video is a live stream, it is transcribed so that when the video resumes playback, the live stream content during the transcription period is provided to the viewer, preventing them from missing the live stream content and further enhancing their viewing experience; if the video is not a live stream, playback is directly paused.

[0105] In an optional embodiment, after controlling the video to pause playback, the method further includes:

[0106] In response to all viewers returning their gaze to the video playback area of ​​the in-vehicle display device, the video is controlled to continue playing.

[0107] After the video pauses, the number of viewers is continuously acquired through image acquisition to prevent failure to detect changes in the number of viewers in a timely manner. At the same time, the gaze tracking device still acquires the gaze of each viewer. Once it is detected that the gaze of all viewers has returned to the video playback area of ​​the in-vehicle display device, the video playback is controlled to continue. No complicated operation is required from the viewers, thus realizing a seamless video interaction method for in-vehicle viewers.

[0108] In an optional embodiment, after controlling the video to pause playback, the method further includes:

[0109] In response to the fact that some viewers’ gazes return to the playback area of ​​the video on the in-vehicle display device, a second operation prompt is displayed on the in-vehicle display device; in response to the operation result of any of the viewers on the second operation prompt, the video playing on the in-vehicle display device is paused.

[0110] After the video pauses, if some viewers' attention returns to the video playback area on the in-vehicle display, it indicates that some viewers may want to continue watching the video. Therefore, a second operation prompt can be displayed on the in-vehicle display. Based on any viewer's response to the second operation prompt, the paused video playback on the in-vehicle display is controlled. If no response to the second operation prompt is detected, the video playback remains paused.

[0111] The second operation prompt may include continuing playback. Similar to the first operation prompt, the second operation prompt may further include other prompts, controls, and / or buttons, such as indicating to play the previous video, play the next video, adjust screen brightness and / or volume, etc., but is not limited to these. The second operation prompt may be a function bar with controls, or a pop-up window with query statements and buttons, etc., without specific limitations here.

[0112] If the second operation prompt also includes other prompts, controls, and / or buttons, the viewer's operation result in response to the second operation prompt may also include the operation result in response to the other prompts, controls, and / or buttons, and the paused video can be controlled based on this operation result. For example, if the second operation prompt also includes a control indicating screen brightness adjustment, the viewer can adjust the video's screen brightness according to their own needs using the control indicating screen brightness adjustment.

[0113] As an example, such as Figure 5 As shown, in the vehicle display device 100, the video is not played in full screen. The video playback area 200 does not occupy the entire screen of the vehicle display device 100. The first type of second operation prompt 410 can float below and outside the playback area without obstructing the screen of the playback area 200. The first type of second operation prompt 410 is a function bar that includes controls for continuing playback, indicating playback of the previous video, indicating playback of the next video, indicating brightness adjustment, and indicating volume adjustment. Upon receiving the operation result of any viewer on any control in the first type of second operation prompt 410, the paused video can be controlled according to the operation result; for example... Figure 6 As shown, in the vehicle display device 100, the video is played in full screen, and the video playback area 200 occupies the entire screen of the vehicle display device 100. The first type of second operation prompt 410 can float below the playback area, has a certain degree of transparency, and does not completely obscure the image of the playback area 200; as shown Figure 7 As shown, in the vehicle-mounted display device 100, the second type of second operation prompt 420 can be a control for continuing playback, located in the middle of the playback area; as... Figure 8As shown, in the vehicle display device 100, the video is played in full screen, and the video playback area 200 occupies the entire screen of the vehicle display device 100. The third type of second operation prompt 430 can be a pop-up window that includes an inquiry statement "Continue playing?" and "Yes" and "Cancel" buttons, with a certain degree of transparency, so as not to completely obscure the screen of the playback area 200.

[0114] In addition, the methods for moviegoers to operate in response to the above-mentioned second operation prompt include, but are not limited to, touch operation, voice command, and gesture operation.

[0115] After the video pauses, once all viewers' attention returns to the video playback area on the in-vehicle display device, indicating that all viewers' attention has returned to the video, the in-vehicle display device can be controlled to continue playing the video.

[0116] In an optional embodiment, after controlling the video to pause playback, the method further includes:

[0117] Start the eye-closing timer; in response to the above-mentioned eye-closing time exceeding the preset eye-closing time threshold, control the above-mentioned vehicle display device to enter the screen sleep state.

[0118] The number of moviegoers can be determined using images captured from inside the vehicle by an image acquisition device. If the number of moviegoers is not zero and no eye contact of a moviegoer can be detected, the moviegoer may be napping or sleeping. Specifically, if the number of moviegoers is not zero and no eye contact of a moviegoer is detected, it indicates that the moviegoer is in a closed-eye state and may be napping or sleeping.

[0119] To further determine the current state of moviegoers, image analysis can be performed on the in-vehicle images captured by the image acquisition device to determine whether the moviegoers are in a closed-eye state. If the time the moviegoers are in a closed-eye state exceeds a preset threshold, it indicates that the moviegoers are in a closed-eye state, possibly taking a nap or sleeping. If it is determined that the moviegoers do not currently need to use the in-vehicle display device, the in-vehicle display device can be controlled to enter a screen sleep state, saving power and providing a good resting atmosphere for the moviegoers, thereby improving the moviegoers' experience.

[0120] Furthermore, the above method also includes:

[0121] In response to the fact that the aforementioned in-vehicle display device is a rear-seat display device, the sleep timer is started after the aforementioned rear-seat display device enters the screen sleep state;

[0122] In response to the aforementioned sleep time exceeding a preset sleep time threshold, the aforementioned rear-row display devices are controlled to switch from the unfolded state to the retracted state.

[0123] When the in-vehicle display device is a foldable rear-seat display device, the system can determine whether to switch the rear-seat display device from the unfolded state to the retracted state based on whether its sleep time exceeds a preset sleep time threshold. If the sleep time exceeds the preset sleep time threshold, the probability that the moviegoers will continue to use the rear-seat display device in the near future is low. Therefore, the rear-seat display device can be automatically switched from the unfolded state to the retracted state to provide ample space for the occupants. If the system detects that the moviegoers' gaze has returned to the video playback area of ​​the rear-seat display device before the sleep time has reached the preset sleep time threshold, the sleep time of the rear-seat display device can be automatically ended, the paused video can be replayed, and a second operation prompt can be displayed.

[0124] In addition, when the in-vehicle display device is another display device, the sleep timer can be left off. Once the viewer's gaze returns to the video playback area on the in-vehicle display device, the sleep timer of the rear display device can be automatically terminated, the paused video can be re-displayed, and a second operation prompt can be displayed, thus achieving a screen start-up method that is imperceptible to the viewer.

[0125] It should be noted that in the vehicle display device control method of this invention embodiment, when any one or more of the vehicle's central control display device and passenger-side display device, and the rear display device are playing videos simultaneously, the corresponding viewer for each vehicle display device should be determined, and the line of sight of the viewer corresponding to each vehicle display device should be further determined, in order to avoid the occurrence of erroneous control.

[0126] As an example, if both the front passenger display and the rear passenger display are playing videos simultaneously, and the occupants include the front passenger and two rear passengers, then the front passenger is the viewer of the front passenger display, and the rear passenger is the viewer of the rear passenger display. In this situation, the video playback on the front passenger display should be controlled based on the viewer's line of sight, and the video playback on the rear passenger display should be controlled based on the viewer's line of sight. Conversely, the video playback on the front passenger display should not be controlled based on the viewer's line of sight, thus avoiding erroneous control and a degraded viewing experience.

[0127] The following describes a specific embodiment of the control method for in-vehicle display devices.

[0128] like Figure 9 As shown, the vehicle-mounted display device control method of this embodiment may include the following steps S901 to S914:

[0134] According to the preset pause playback mode, the video is paused and a first operation prompt including continue playback is displayed; in response to any of the viewers selecting continue playback in the first operation prompt, the video is resumed playback.

[0135] Furthermore, after controlling the video to continue playing, the method further includes: recording the video playback progress corresponding to the control of the video to continue playing; in response to detecting that some viewers' gazes have returned to the playback area of ​​the video on the vehicle display device, determining the missed video duration based on the video playback progress corresponding to the continued playback, and displaying a prompt message asking whether to rewind and play the video segment corresponding to the missed video duration.

[0136] Furthermore, after controlling the video to continue playing, the method further includes: in response to the first operation prompt being displayed more than a preset display count threshold, recording the corresponding video playback progress for each time the video is controlled to continue playing; in response to detecting that some viewers' gazes have returned to the playback area of ​​the video on the in-vehicle display device, determining the corresponding missed video duration for each video playback progress, and displaying a prompt message on whether to rewind and play the video segment corresponding to the missed video duration based on each missed video duration.

[0137] Step S906: In response to the operation result of any of the above-mentioned viewers on other prompts, controls or buttons in the first operation prompt, adjust the video based on the operation result; for example, other controls may include a pause playback control, a control indicating the playback of the previous video, a control indicating the playback of the next video, a control indicating the adjustment of screen brightness and a control indicating the adjustment of volume;

[0138] Step S907: In response to the fact that the eyes of all the aforementioned viewers are outside the playback area of ​​the video on the aforementioned vehicle display device, control the video to pause playback.

[0139] Step S908: In response to the fact that the eyes of all the aforementioned viewers are focused on the playback area of ​​the video on the aforementioned vehicle-mounted display device, control the playback of the aforementioned video;

[0140] In step S909, regardless of whether it is step S902, step S905 or step S907, after controlling the above video to pause playback, in response to the inability to detect the gaze of any viewer, start the eye-closed time timer.

[0141] Step S910: In response to the above-mentioned eye-closing time exceeding the preset eye-closing time threshold, control the above-mentioned vehicle display device to enter the screen sleep state.

[0142] Furthermore, when the in-vehicle display device is a foldable rear-seat display device, after the rear-seat display device enters the screen sleep state, the sleep timer is started; in response to the sleep time exceeding the preset sleep time threshold, the rear-seat display device is controlled to switch from the unfolded state to the retracted state.

[0143] Step S911: In response to the detection of the viewer's gaze when the closed-eye time does not exceed the preset closed-eye time threshold, and when all the viewer's gaze returns to the playback area of ​​the video on the vehicle display device, the video is controlled to continue playing.

[0144] Step S912: In response to the detection of the viewer's gaze when the closed-eye time does not exceed the preset closed-eye time threshold, if some viewers' gazes return to the playback area of ​​the video on the vehicle display device, a second operation prompt is displayed on the vehicle display device.

[0145] Step S913: In response to the operation result of any of the above-mentioned viewers to the second operation prompt indicating that playback should continue, control the paused video in the above-mentioned vehicle display device to continue playing.

[0146] Step S914: In response to the operation result of any of the above-mentioned viewers on the other prompts, controls or buttons in the second operation prompt other than the continue playback prompt, control the video based on the operation result, and control the continuous pause playback on the above-mentioned vehicle display device.

[0147] According to the vehicle-mounted display device control method of the present invention, when a video is played on the vehicle-mounted display device in the vehicle cabin, the method controls the video played on the vehicle-mounted display device by obtaining the line of sight of each viewer in the vehicle cabin.
