[0056] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0057] Embodiment 1

[0058] At present, when users use screen devices such as seat back screens installed in vehicles, they usually adjust the playback volume of the screen device by triggering the corresponding adjustment button. However, in a situation where multiple users use the same screen device at the same time, if the playback volume of the screen device is too high, it will affect the user experience of users who are closer to the screen device, and if the playback volume of the screen device is too low, it will affect the user experience of users who are farther away from the screen device. Therefore, in order to ensure the user experience of each user, one of the users is usually required to adjust the playback volume to an appropriate level, and usually the user needs to adjust the playback volume repeatedly for multiple times before adjusting the playback volume to an appropriate level. Therefore, the existing playback volume adjustment method of screen devices has poor adjustment flexibility, which affects the user experience.

[0059] Based on this, the present application proposes a first embodiment of a playback volume adjustment method, which is applied to a screen device, wherein the screen device is provided with a line of sight sensor, please refer to Figure 1 The playback volume adjustment method includes steps S10 to S40:

[0060] Step S10, dynamically collecting the number of gaze points in the display area of ​​the screen device through the sight line sensor;

[0061] It should be noted that the number of gaze points is used to characterize the number of sight lines falling on the display area of ​​the screen device. The visual sensor can be replaced by a device that can collect the number of gaze points, such as a visual tracker or an eye tracker. When setting a sight line sensor on the screen device, multiple sight line sensors can be set, or only one sight line sensor can be set, which is not specifically limited in this embodiment.

[0062] When dynamically collecting the number of gaze points in the display area of ​​the screen device through the line of sight sensor, the collection can be performed in real time or periodically at certain time intervals, which is not specifically limited in this embodiment.

[0063] In a feasible implementation, if the screen device is provided with a plurality of gaze sensors, step S10 may include: dynamically collecting the number of sub-fixation points in the display area of ​​the screen device through each of the gaze sensors; determining the mode of each of the sub-fixation point numbers as the number of fixation points, or determining the average of each of the sub-fixation point numbers as the number of fixation points.

[0064] Step S20, if it is detected that the number of gaze points is greater than the preset number of gaze points, determining the interval distance between the target user corresponding to each gaze point and the screen device;

[0065] It should be noted that the target user refers to the user who is looking at the screen device, the preset number of gaze points is the basis for determining whether multiple users are using the screen device, and the interval distance refers to the distance between the target user and the screen device.

[0066] In a feasible implementation, the distance between each target user and the screen device can be detected by a distance sensor or radar or other device capable of detecting the distance. The distance sensor or radar or other device capable of detecting the distance can be set on the screen device or on other devices connected to the screen device, and this implementation does not specifically limit this.

[0067] Step S30, determining a target playback volume of the screen device according to each of the interval distances;

[0068] It should be noted that the target playback volume refers to the playback volume that the screen device needs to reach at the current moment.

[0069] In a feasible implementation, when determining the target playback volume of the screen device according to each interval distance, the average of the playback volumes corresponding to each interval distance can be determined first to obtain the average playback volume. At this time, the average playback volume can be directly used as the target playback volume. In order to further ensure the user experience of users who are closer to the screen device, the maximum playback volume associated with the minimum interval distance among the interval distances can be further obtained. If the maximum playback volume associated with the minimum interval distance is greater than or equal to the average playback volume, the average playback volume can be directly used as the target playback volume; if the maximum playback volume associated with the minimum interval distance is less than the average playback volume, the maximum playback volume associated with the minimum interval distance is used as the target playback volume.

[0070] In other implementations, when determining the target playback volume of the screen device according to each interval distance, the average of the playback volume corresponding to the maximum interval distance and the playback volume corresponding to the minimum interval distance among the interval distances may be used as the target playback volume.

[0071] The above are only two feasible implementations of step S30 provided in this embodiment, and this embodiment does not specifically limit the specific implementation of step S30.

[0072] Step S40: adjusting the playback volume of the screen device to the target playback volume.

[0073] The present embodiment provides a playback volume adjustment method, which is applied to a screen device. The present embodiment sets a gaze sensor on the screen device to dynamically collect the number of gaze points in the display area of ​​the screen device through the gaze sensor, so as to determine whether multiple users are using the screen device through the number of gaze points; if it is detected that the number of gaze points is greater than the preset number of gaze points, it means that multiple users are using the screen device at this time, and it is necessary to determine the interval distance between each user who is looking at (i.e., using) the screen device and the screen device; then determine the target playback volume to which the screen device needs to be adjusted through each interval distance; and then adjust the playback volume of the screen device to the target playback volume.

[0074] In summary, after determining that multiple users are using the screen device, this embodiment can determine the target playback volume to which the screen device needs to be adjusted by the distance between each target user and the screen device, so that the playback volume of the screen device can be adaptively adjusted according to the distance between each target user and the screen device. The entire playback volume adjustment process does not require human intervention, thereby overcoming the existing technical defect that requires the user to repeatedly adjust the playback volume of the screen device to an appropriate size, improving the adjustment flexibility of the playback volume of the screen device, and thereby improving the user experience.

[0075] In a feasible implementation manner, the step S30: determining the target playback volume of the screen device according to each of the interval distances, includes steps S31 to S34:

[0076] Step S31, determining each target interval distance from each of the interval distances;

[0077] It should be noted that the target interval distance refers to the interval distance used to determine the target playback volume.

[0078] As an example, the step S31: determining each target interval distance from each interval distance includes steps S311 to S316:

[0079] Step S311, selecting an interval distance smaller than a preset distance from each of the interval distances as a first interval distance, and selecting the remaining interval distances as a second interval distance;

[0080] It should be noted that the first spacing distance refers to the spacing distance that is smaller than the preset distance among the spacing distances, and the second spacing distance refers to the spacing distance that is greater than or equal to the preset distance among the spacing distances.

[0081] Step S312, counting a first number of each of the first interval distances and a second number of each of the second interval distances;

[0082] Step S313, if the first number and the second number are both one, taking each of the interval distances as the target interval distance;

[0083] It can be understood that if the first number and the second number are both one, it means that only two users are looking at the screen device at the current moment, and the distances between the two users and the screen device can be used as the target distances.

[0084] Step S314, if the first number and the second number are not both equal, determining whether the first number is greater than the second number;

[0085] Step S315: if yes, taking each of the first interval distances as each of the target interval distances;

[0086] Step S316: if not, taking each of the second interval distances as each of the target interval distances.

[0087] In this example, by screening and counting the first number of each first interval distance and the second number of each second interval distance, and comparing the first number with the second number, it is possible to determine whether among the users who are looking at the screen device at the current moment, there are more users who are closer to the screen device or more users who are farther away from the screen device; if there are more users who are closer to the screen device, the user experience of the users who are closer to the screen device is prioritized, that is, the first interval distances are used as the target interval distances; if there are more users who are farther away from the screen device, the user experience of the users who are farther away from the screen device is prioritized, that is, the second interval distances are used as the target interval distances.

[0088] As another example, when determining each target interval distance from each interval distance, each interval distance may be directly used as each target interval distance.

[0089] The above are merely two feasible examples of step S31 provided in this embodiment, and this embodiment does not specifically limit the specific implementation examples of step S31.

[0090] Step S32, obtaining the maximum interval distance and the minimum interval distance among the target interval distances;

[0091] It should be noted that the maximum interval distance refers to the maximum value among the target interval distances, and the minimum interval distance refers to the minimum value among the target interval distances.

[0092] When obtaining the maximum interval distance and the minimum interval distance among the target interval distances, they can be obtained from the local device (ie, the playback volume adjustment device) or from other devices connected to the local device, which is not specifically limited in this embodiment.

[0093] Step S33, searching for a first playback volume corresponding to the minimum interval distance, and searching for a second playback volume corresponding to the maximum interval distance;

[0094] It should be noted that the first playback volume refers to the playback volume that the screen device needs to reach corresponding to the minimum interval distance, and the second playback volume refers to the playback volume that the screen device needs to reach corresponding to the maximum interval distance. The playback volume is positively correlated with the interval distance, that is, the longer the interval distance, the louder the playback volume.

[0095] As an example, a volume configuration table recording the correspondence between the interval distance and the playback volume may be preset, so that step S33 may include: searching the preset volume configuration table for the first playback volume corresponding to the minimum interval distance, and searching the preset volume configuration table for the second playback volume corresponding to the maximum interval distance. The volume configuration table may be set in a local device (i.e., a playback volume adjustment device), or may be set in other devices connected to the local device, and this example does not specifically limit this.

[0096] Step S34: determine an average value of the first playback volume and the second playback volume to obtain the target playback volume.

[0097] In this implementation, first, each interval distance used to determine the target playback volume is determined from each interval distance to obtain each target interval distance; then the maximum interval distance and the minimum interval distance of each target interval distance are obtained; then the first playback volume corresponding to the minimum interval distance is found, and the second playback volume corresponding to the maximum interval distance is found; finally, by determining the average value of the first playback volume and the second playback volume, the target playback volume to which the screen device needs to be adjusted can be obtained.

[0098] Therefore, this embodiment proposes an adjustment scheme that enables the playback volume of the screen device to be adaptively adjusted according to the interval distance between each target user and the screen device, by determining the average of the first playback volume corresponding to the minimum interval distance and the second playback volume corresponding to the maximum interval distance in the target interval distance, so as to obtain a more appropriate playback volume that the screen device needs to reach at the current moment. As a result, the entire playback volume adjustment process does not require manual participation, thereby overcoming the existing technical defect that the user needs to repeatedly adjust the playback volume of the screen device to an appropriate size, improving the adjustment flexibility of the playback volume of the screen device, and thus improving the user experience.

[0099] In another feasible implementation manner, the step S30: determining the target playback volume of the screen device according to each of the interval distances, includes steps S301 to S303:

[0100] Step S301, determining each target interval distance from each interval distance;

[0101] Step S302, searching for a third playback volume corresponding to each target interval distance;

[0102] It should be noted that the third playback volume refers to the playback volume that the screen device corresponding to the target spacing distance needs to reach.

[0103] Step S303: determine an average value of each of the third playback volumes to obtain the target playback volume.

[0104] In this implementation, first, each interval distance used to determine the target playback volume is determined from each interval distance to obtain each target interval distance; then, the third playback volume corresponding to each target interval distance is found; finally, by determining the average value of each third playback volume, the target playback volume to which the screen device needs to be adjusted can be obtained.

[0105] Therefore, this embodiment proposes an adjustment scheme that enables the playback volume of the screen device to be adaptively adjusted according to the interval distance between each target user and the screen device, by determining the average value of the third playback volume corresponding to each target interval distance, so as to obtain a more appropriate playback volume that the screen device needs to reach at the current moment. Compared with the previous embodiment, this embodiment takes into account the third playback volume corresponding to all target interval distances, that is, the target playback volume is determined based on the overall situation of all users who are looking at the screen device. Therefore, the target playback volume determined by this embodiment can enable each target user to have a better user experience than the target playback volume determined by the previous embodiment. Therefore, this embodiment can further improve the user experience on the basis of improving the adjustment flexibility of the playback volume of the screen device.

[0106] Embodiment 2

[0107] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 , the playback volume adjustment method further includes:

[0108] Step A10, if the number of gaze points is detected to be zero, obtaining the duration of the continuous detection of the number of gaze points being zero and the current playback volume of the screen device;

[0109] When a user uses a screen device installed in a vehicle, the screen device may be in a high volume state for a long time once it is turned on, unless the user manually adjusts the playback volume to reduce the playback volume of the screen device. Considering that the user will not use the screen device all the time after it is turned on, if the screen device is still in a high volume state when the user is not using the screen device, it will cause unnecessary energy consumption for the vehicle.

[0110] It should be noted that the current playback volume refers to the playback volume of the screen device at the current moment.

[0111] When obtaining the duration of the continuous detection of the number of gaze points as zero and the current playback volume of the screen device, it can be obtained from the local device (i.e., the playback volume adjustment device) or from other devices connected to the local device. This embodiment does not specifically limit this.

[0112] Step A20, if the duration is greater than or equal to a preset duration, determining a target volume reduction coefficient corresponding to the duration, wherein the duration is positively correlated with the target volume reduction coefficient;

[0113] It should be noted that the volume reduction coefficient is used to determine the reduction amount of the playback volume of the screen device, and the volume reduction coefficient is greater than 0 and less than or equal to 1. The target volume reduction coefficient refers to the volume reduction coefficient under the duration at the current moment. The preset duration is used as a basis for determining whether no user has used the screen device for a long time.

[0114] In a feasible implementation manner, the step A20: determining the target volume reduction coefficient corresponding to the duration, includes steps A21 to A22:

[0115] Step A21, determining the target duration interval in which the duration is located in each preset duration interval;

[0116] Step A22: Using the volume reduction coefficient associated with the target duration interval as the target volume reduction coefficient.

[0117] In this embodiment, by determining the target duration interval in each preset duration interval, the volume reduction coefficient associated with the target duration interval is used as the target volume reduction coefficient. Thus, this embodiment uses the duration interval as the basis for determining the target volume reduction coefficient, that is, updating the target volume reduction coefficient according to the duration interval (one duration interval corresponds to one volume reduction coefficient), rather than updating the target volume reduction coefficient by duration (one duration corresponds to one volume reduction coefficient), thereby reducing the space occupied by the corresponding data storage area. It is understandable that if the target volume reduction coefficient is updated directly by duration, it is necessary to store the volume reduction coefficients corresponding to different durations in the corresponding data storage area, which will cause the data storage area to store a large amount of data.

[0118] In another feasible implementation, a coefficient configuration table for recording the association between different durations and volume reduction coefficients may be provided, so that step A20 may include: searching the preset coefficient configuration table for the target volume reduction coefficient corresponding to the duration.

[0119] The above are only two feasible implementation methods of step A20 provided in this embodiment, and this embodiment does not specifically limit the specific implementation method of step A20.

[0120] Step A30: gradually reducing the playback volume of the screen device according to the target volume reduction coefficient and the current playback volume.

[0121] In a feasible implementation, step A30 may include: determining whether the current playback volume is greater than a preset playback volume; if so, determining the difference between the current playback volume and the preset playback volume to obtain a playback volume difference; determining a volume reduction amount based on the playback volume difference and the target volume reduction coefficient; and reducing the playback volume of the screen device based on the volume reduction amount.

[0122] In a feasible implementation manner, the step of determining the volume reduction amount according to the playback volume difference and the target volume reduction coefficient may include: determining the product of the playback volume difference and the target volume reduction coefficient as the volume reduction amount. In other implementation manners, the volume reduction amount may also be determined based on the current playback volume, which is not specifically limited in this embodiment.

[0123] In this embodiment, if the number of gaze points detected is zero, it means that no user is using the screen device at this time, then the duration of the continuous detection of the number of gaze points as zero and the current playback volume of the screen device are obtained; then the target volume reduction coefficient corresponding to the duration is determined, so as to gradually reduce the playback volume of the screen device through the target volume reduction coefficient and the current playback volume.

[0124] In summary, since the present embodiment gradually reduces the playback volume of the screen device, rather than directly reducing the playback volume to the minimum playback volume, the user's experience can be improved. Moreover, in the process of gradually reducing the playback volume of the screen device, since the duration is positively correlated with the target volume reduction coefficient, when the target volume reduction coefficient is used to gradually reduce the playback volume of the screen device, it can show that the amount of each reduction in the playback volume of the screen device will increase with the increase in the duration, that is, the reduction in the volume of the screen device is small at the beginning of the reduction, so when dealing with the scenario where the user has not used the screen device for a short time, it can overcome the technical defect that the user needs to wait for a long time before the playback volume of the screen device returns to normal due to the excessive reduction in the playback volume of the screen device in a short time. Therefore, the present embodiment can achieve the technical effect of reducing unnecessary energy consumption caused by the screen device on the basis of ensuring the user's experience of the screen device.

[0125] In a feasible implementation manner, the step A30: gradually reducing the playback volume of the screen device according to the target volume reduction coefficient and the current playback volume, includes steps A31 to A35:

[0126] Step A31, determining whether the current playback volume is greater than a preset playback volume;

[0127] It should be noted that the preset playback volume refers to the minimum playback volume that the screen device needs to maintain.

[0128] Step A32: if yes, determine the difference between the current playback volume and the preset playback volume to obtain the playback volume difference;

[0129] Step A33, determining the product of the target volume reduction coefficient and the current playback volume to obtain a volume reduction amount;

[0130] Step A34, if the playback volume difference is less than or equal to the volume reduction amount, reducing the playback volume of the screen device to the preset playback volume;

[0131] Step A35: if the playback volume difference is greater than the volume reduction amount, then based on the volume reduction amount, reduce the playback volume of the screen device.

[0132] In this implementation, it is first determined whether the current playback volume is greater than the preset playback volume; if the current playback volume is greater than the preset playback volume, it means that the playback volume of the screen device can be reduced, then the difference between the current playback volume and the preset playback volume is determined to obtain the playback volume difference; then the product of the target volume reduction coefficient and the current playback volume is determined to obtain the volume reduction amount; if the playback volume difference is less than or equal to the volume reduction amount, it means that the amount by which the playback volume of the screen device is required to be reduced exceeds the maximum amount by which the playback volume of the screen device can be reduced, then the playback volume of the screen device can be directly adjusted to the preset playback volume; if the playback volume difference is greater than the volume reduction amount, it means that the amount by which the playback volume of the screen device is required to be reduced does not exceed the maximum amount by which the playback volume of the screen device can be reduced, then the playback volume of the screen device is reduced according to the volume reduction amount.

[0133] For example, to help understand the technical concept or technical principle of this application, please refer to Figure 3 , assuming that the current playback volume of the screen device is 10, the preset playback volume is 2, and the preset duration is 2s. When the duration of zero gaze points is 2s, the target volume reduction coefficient is 0.1, and the volume reduction amount is 10*0.1=1, so that the playback volume of the screen device is reduced to 9; when the duration of zero gaze points is 3s, the target volume reduction coefficient is 0.3, and the volume reduction amount is 9*0.3=2.7, so that the playback volume of the screen device is reduced to 6.3; when the duration of zero gaze points is 4s, the target volume reduction coefficient is 0.5, and the volume reduction amount is 6.3*0.5=3.15, so that the playback volume of the screen device is reduced to 3.15; when the duration of zero gaze points is 5s, the target volume reduction coefficient is 1, and the volume reduction amount is 3.15*1=3.15, and the playback volume difference between the current playback volume and the preset playback volume is 3.15-2=1.15<volume reduction amount 3.15, so the playback volume of the screen device is reduced to 2.

[0134] It should be noted that the above examples are only used to assist in understanding the present application and do not constitute a limitation on the playback volume adjustment method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
