[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with one or more embodiments of this specification. Rather, they are merely examples of apparatuses and methods consistent with some aspects of one or more embodiments of this specification as detailed in the appended claims.

[0047] It should be noted that the steps of the corresponding methods are not necessarily performed in the order shown and described in this specification in other embodiments. In some other embodiments, the methods may include more or fewer steps than described in this specification. Furthermore, a single step described in this specification may be broken down into multiple steps in other embodiments; and multiple steps described in this specification may be combined into a single step in other embodiments.

[0048] To address the technical problem that manual control of ambient lighting cannot meet the needs of automated control, this application provides an ambient lighting control method, including detecting the driver's gaze position inside the vehicle; obtaining the driver's state based on the gaze position; recognizing the driver's facial expressions to obtain the driver's user emotion; and controlling the ambient lighting in the vehicle to operate in a mode corresponding to the user's emotion in response to the driver's state and user emotion.

[0049] In this embodiment, the ambient lighting inside the vehicle is controlled to present a display effect that adjusts the driver's mood based on the user's emotions. Thus, by responding to the driver's emotions, the ambient lighting is automatically controlled, thereby meeting the needs of automated ambient lighting control and improving the user experience.

[0050] The ambient lighting control method of this application embodiment is applied to a vehicle. The vehicle includes one or more of wearable devices, electronic devices, and image acquisition devices.

[0051] The electronic devices include processors or controllers. The processor can be used to control the entire vehicle. For example, the controller can be, but is not limited to, a center console.

[0052] Image acquisition devices are used to collect images containing user-related information. These devices may include, but are not limited to, OMS (Driver Monitoring System) cameras. For example, image acquisition devices may include, but are not limited to, cameras installed in a vehicle and / or cameras in wearable devices.

[0053] In some embodiments, the wearable device is, for example, glasses and does not include a processor. The processor is an in-vehicle processor. The in-vehicle processor is connected to the wearable device and is used to acquire signals transmitted by the wearable device and transmit data to the wearable device. While the user is wearing the wearable device, the wearable device converts the acquired data into electrical signals and transmits them to the processor. The processor then transmits the resulting control signals to the wearable device, and the user can observe the content generated by the control signals by wearing the wearable device. Thus, by combining the wearable device and the in-vehicle processor, the ambient light control method of this application embodiment is realized.

[0054] In other embodiments, the wearable device is, for example, eyeglasses. The eyeglasses include a processor and a camera. The camera includes a binocular camera and an OMS camera, and the processor can execute the ambient light control method of this application. The processor can be embedded inside the eyeglasses, providing a degree of portability. Thus, one or more processors of this application are used to implement the ambient light control method of the embodiments of this application.

[0055] Figure 1 The diagram shown is a flowchart illustrating the ambient light control method provided in an embodiment of this application.

[0056] like Figure 1 As shown, the control method for this ambient light includes the following steps 110 to 140:

[0057] Step 110: Detect the driver's gaze position inside the vehicle.

[0058] Gaze position is used to determine whether the driver is looking at the ground outside the vehicle or at the road conditions ahead, thus assessing the driver's condition. When the driver is looking at the ground outside the vehicle or at the road conditions ahead, it indicates that the driver's driving condition is likely normal. When the driver is not looking at the ground outside the vehicle or at the road conditions ahead, such as by looking down, squinting, or closing their eyes, it indicates that the driver's driving condition may be abnormal.

[0059] Step 120: Obtain the driver's status based on the gaze position.

[0060] Driver status is used to reflect whether the driver's driving condition is normal. Driving status is divided into normal driving status and abnormal driving status. Abnormal driving status is such as fatigued driving status. Fatigued driving status refers to a driver's state where they are not paying attention to the ground outside the vehicle or the road conditions ahead, and the opening and closing of their eyes reaches a preset threshold for fatigue. This can accurately determine the driver's status.

[0061] Step 120 above can be implemented through the following various embodiments:

[0062] In some embodiments of step 120 above, (1) the driver's eye information is acquired from the in-vehicle OMS camera. (2) The eye opening degree is determined based on the eye information. (3) If the eye opening degree reaches the fatigue predetermined opening degree and the gaze position deviates from the outside of the vehicle by a preset threshold, the driver's state is determined to be fatigued. (4) If the eye opening degree does not reach the fatigue predetermined opening degree or the gaze position is outside the vehicle, the driver's state is determined to be normal. The above-mentioned normal state is also used to reflect the driver's non-fatigue driving state.

[0063] The aforementioned fatigue state is used to reflect fatigued driving. The predetermined eye opening degree during fatigue is less than a predetermined percentage of the initial eye opening degree. This can improve the accuracy of driver condition assessment.

[0064] A preset threshold is used to reflect the driver's current continuous state. The preset threshold can be, but is not limited to, a preset duration and / or a preset frequency. The preset duration can be set according to user needs. For example, the preset threshold may be less than 3 seconds. For instance, the preset threshold could be 1 second, 2 seconds, or 3 seconds. The preset frequency can be set according to user needs. For example, the preset frequency may be greater than 3 times per unit time. For instance, the preset frequency could be 3 times, 4 seconds, or 5 seconds per minute, or even more positive integer seconds.

[0065] In this embodiment of the application, the driver's state is not misjudged as fatigued due to brief blinks or brief visual deviations, thus improving the accuracy of driver state determination.

[0066] In some embodiments of step 120 above, the driver's fatigue state is determined solely by the degree of eye opening or solely by observing the road conditions ahead of the vehicle from the perspective of the gaze position. Examples will not be provided here.

[0067] Step 130: Recognize the facial expressions of the driver inside the vehicle to obtain the driver's emotions.

[0068] Step 140: In response to the driver's state and the user's emotions, control the ambient lighting inside the vehicle to a working mode corresponding to the user's emotions. This working mode displays effects designed to adjust the driver's mood.

[0069] In this embodiment, the ambient lighting inside the vehicle is controlled to display an effect that adjusts the driver's mood based on the user's emotions. Thus, the ambient lighting is automatically controlled to respond to the driver's emotions, thereby improving the user experience. Furthermore, by visually displaying the driver's emotions when other passengers are present, other passengers can also perceive the driver's emotions and choose appropriate actions.

[0070] Figure 2 As shown Figure 1 The flowchart illustrates steps 110 and 130 of the ambient light control method shown. Step 110 may further include steps 111 and 112; step 130 may further include steps 131 and 132.

[0071] Combination Figure 1 ,like Figure 2 As shown, in step 111, the driver's eye movement information is acquired by the binocular camera on the wearable glasses.

[0072] The aforementioned eye movement information parameters include one or more of the following: average pupil diameter, pupil dilation velocity, first fixation time, fixation duration, and total number of fixations. These data are proportional to the fixation position, allowing for eye tracking of the driver's eyes to determine their fixation position within the vehicle.

[0073] Step 111 uses wearable glasses to track the eyeballs, thereby determining eye movement information.

[0074] Step 112: Based on eye movement information, perform eye tracking on the driver's eyes to obtain the driver's gaze position inside the vehicle.

[0075] Step 131: Obtain the facial information of the driver inside the vehicle captured by the OMS camera on the wearable glasses; the OMS camera and the binocular camera are set facing each other.

[0076] Step 132: Recognize facial expressions to obtain the driver's emotions inside the vehicle.

[0077] In this embodiment, the OMS camera of the wearable glasses can work in conjunction with the binocular camera of the wearable glasses for eye tracking. Eye tracking detects the driver's gaze position, while the OMS camera detects the driver's driving state and facial expressions. Analyzing the driver's gaze position and driving state helps determine their facial emotions. Since both the OMS camera and the binocular camera of the wearable glasses move with the head, they can promptly capture the user's emotions, improving the timeliness of ambient lighting control.

[0078] continue Figure 1 and Figure 2 As shown, the driver is in a fatigued state; the user's emotion is fatigued. Step 140 above has several embodiments:

[0079] In one embodiment of step 140 above, in response to fatigue state and fatigued mood, a first operating mode for displaying a warning color corresponding to the fatigued mood is determined from a preset correspondence between the user's mood and the ambient lighting in the vehicle. The ambient lighting is then controlled to be in the first operating mode. Thus, the driver and other people are alerted by the first operating mode displaying the warning color. In other embodiments, in response to fatigue state and fatigued mood, a first operating mode for displaying a warning color corresponding to the fatigued state and fatigued mood is determined from a preset correspondence between the user's mood and the ambient lighting in the vehicle. The ambient lighting is then controlled to be in the first operating mode. By pre-establishing a preset correspondence between fatigue state and fatigued mood and the operating mode of the ambient lighting in the vehicle, the timeliness of subsequent ambient lighting control can be improved.

[0080] The warning color is used to provide a warning. The warning color can be, but is not limited to, red. Of course, red can be one or more of bright red and watermelon red.

[0081] The preset correspondence between user emotions and in-car ambient lighting is used to reflect the corresponding colors of the ambient lighting, so as to match the driver's emotions.

[0082] The above methods also include: linking seat vibrations to generate an alarm sound. This allows for more timely alerts to the driver through seat vibration and an alarm sound.

[0083] The first embodiment of step 140 above and the embodiment of linking the seat vibration and controlling the generation of an alarm sound above can be implemented in combination or separately, and will not be described in detail here.

[0084] The following are examples of applications of the embodiments of this application:

[0085] When the driver is determined to be fatigued, the ambient lighting inside the vehicle will turn red. Bright red ambient lighting is a driver fatigue warning light.

[0086] In the second embodiment of step 140 above, the driver's state is normal; the user's emotion is positive. In response to the normal state and the user's positive emotion, a second operating mode corresponding to the user's positive emotion and displaying a soothing color is determined from a preset correspondence between the user's emotion and the operating mode of the ambient lighting. The ambient lighting is then controlled to operate in the second operating mode. This allows the driver and other passengers to be alerted by displaying a soothing color in the second operating mode. By establishing a preset correspondence between the user's positive emotion and the operating mode of the ambient lighting, the timeliness of subsequent ambient lighting control can be improved.

[0087] Soothing colors are used to achieve a calming effect. Examples of soothing colors include blue, green, purple, and / or pink.

[0088] The above-mentioned positive user emotions are used to indicate that the user is in a good mood. Positive user emotions can include, but are not limited to, one or more of the following: enthusiasm, pleasure, excitement, entertainment, inspiration, activity, focus, happiness, relaxation, joy, and reassurance.

[0089] The second and third working modes mentioned above can also present a breathing rhythm effect.

[0090] The following are examples of applications of the embodiments of this application:

[0091] The system detects that the user is fully focused on driving, and eye tracking indicates that the user's eyes are fixed on the ground outside the vehicle. Furthermore, the user's positive emotion is a pleasant mood, so the ambient lighting inside the vehicle changes to a flowing green light to soothe the user's emotions.

[0092] In the third embodiment of step 140 above, the driver's state is normal; the user's emotion is negative; in response to the normal state and the user's negative emotion, a third working mode corresponding to the user's positive emotion and used to display an emotion-evoking color is determined from a preset correspondence between the user's emotion and the working mode of the ambient lighting. The ambient lighting is then controlled to be in the third working mode. By establishing a preset correspondence between the user's negative emotion and the working mode of the ambient lighting, the timeliness of subsequent ambient lighting control can be improved.

[0093] The established pre-defined correspondences include a direct correspondence between user emotions and the operating modes of the ambient lighting in the vehicle. This direct correspondence includes one or more of the following: a pre-defined correspondence between negative user emotions and the operating modes of the ambient lighting; a pre-defined correspondence between positive user emotions and the operating modes of the ambient lighting; a pre-defined correspondence between fatigue and the operating modes of the ambient lighting. In this way, the required pre-defined correspondences are obtained by iterating through all user emotions.

[0094] Of course, the established pre-defined correspondences include pre-classified user emotions into negative, positive, and fatigued emotions, and each of these pre-classified emotions corresponds to a pre-defined working mode of the in-car ambient lighting. In this way, the required pre-defined correspondences can be quickly obtained from each of the pre-classified user emotions.

[0095] Among them, emotionally evocative colors are used to evoke emotions. For example, an emotionally evocative color is orange.

[0096] The above negative user emotions are used to indicate that the user is in a poor emotional state. Negative user emotions may include, but are not limited to, one or more of the following: irritability, sadness, sorrow, anxiety, fear, anger, pain, tension, and hatred.

[0097] The following are examples of applications of the embodiments of this application:

[0098] The system detected that the user was in a bad mood, and eye tracking showed that the user did not look at the road outside the car for 3 seconds within one minute. The ambient light turned orange and flowed in order to evoke the user's emotions.

[0099] In the fourth embodiment of step 140 above, ① in response to the driver's state and the user's emotions, it is determined that the user's emotions have changed from the previous moment; ② based on the preset switching relationship between the ambient lighting modes corresponding to the user's negative emotions and the ambient lighting modes corresponding to the user's positive emotions, a switching mode associated with the user's current emotion switching is determined. After the ambient lighting is in the second working mode, the method further includes ③ recognizing the driver's facial expression as a dissatisfied expression, and switching the default color of the second working mode to the next preset color of the default color. In this way, the ambient lighting can be automatically adjusted by combining the driver's facial expression feedback to the current ambient lighting, thereby improving the autonomy of ambient lighting adjustment.
