[0002] With the construction and development of public transportation, subways and trams have the characteristics of being fast, punctual, comfortable, and environmentally friendly. The proportion of people choosing to take rail transportation in urban public transportation passenger transportation is increasing. In existing subways or trams, generally, display devices for passenger information are set up on the platform and station hall, which are divided into multiple display areas through templates, and can display date, time, train arrival information, emergency information and video advertisements, etc.

[0003] In the prior art, these display areas in the display device are fixed, that is, the font size, color, contrast, etc. are all unchanged. However, passengers have a selection of the content they obtain on the display device, and the fixed setting of the display area in the display device will affect the passengers' acquisition of useful information. For example, sometimes the distance between the display devices of the passenger information system on the subway platform is too large, and passengers cannot see the content clearly and need to get closer to see it clearly; most passengers are more concerned about the arrival time of the train, and the real-time information display contains some content with low attention. This information not only does not serve the passengers, but also makes it difficult for passengers to obtain useful information, making the display device less user-friendly.

[0057] <Method>

[0058] Figure 3 1 is a flow chart of a control method of a display device according to an embodiment of the present disclosure. The control method of the display device may be implemented by the display device. Specifically, the display device may be as follows: Figure 1 Display device 1000 is shown.

[0059] like Figure 3 As shown, the control method of the display device includes the following steps S3100 to S3200:

[0060] Step S3100, obtaining behavior data reflecting passenger behavior.

[0061] The behavior data of this embodiment may include passenger image data collected by a camera and / or passenger voice data collected by a microphone.

[0062] Step S3200: adjusting display parameters of a target display area of ​​a display device according to the behavior data.

[0063] In this embodiment, the display parameter may include at least one of length, width, font size of displayed text, contrast, and backlight brightness.

[0064] In the embodiments of the present disclosure, the behavioral data can reflect the passengers' viewing needs for the content displayed on the display device. Therefore, the display parameters of the target display area that the passengers are concerned about on the display device are adjusted in a targeted manner according to the behavioral data. There is no need to adjust the size of the display device to remind the user, thus saving the hardware cost and occupied space of the display device. In addition, it can also facilitate passengers to capture useful information more quickly, thereby improving the passengers' riding experience.

[0065] In this embodiment, the target display area may be the entire display area of ​​the display device, or may be a partial display area of ​​the display device.

[0066] In one embodiment of the present disclosure, adjusting the display parameters of the target display area of ​​the display device according to the behavior data may include the following steps S3210 to S3220:

[0067] Step S3210: determining whether the target display area meets the first adjustment condition according to the behavior data.

[0068] In this embodiment, the target display area may be any one or more display areas of the display device.

[0069] In one embodiment of the present disclosure, the first adjustment condition may include at least one of the following:

[0070] The ratio between the first number and the second number is greater than or equal to a first threshold, wherein the first number is the number of passengers whose gaze time at the target display area reaches a first set time, and the second number is the number of passengers whose gaze time at the display device reaches the first set time;

[0071] The ratio between the third number and the fourth number is greater than or equal to the second threshold, wherein the third number is the number of passengers gazing at the target display area in the set eye state, and the fourth number is the number of passengers gazing at the display device in the set eye state;

[0072] The voice uttered by the passenger contains keywords corresponding to the target display area.

[0073] In this embodiment, the first threshold and the second threshold may be set based on application scenarios or specific requirements. The first threshold and the second threshold may be equal or different, which is not limited here. For example, the first threshold and the second threshold may both be 0.68.

[0074] Furthermore, the first set time length may be set based on an application scenario or specific requirements. For example, the first set time length may be 3 seconds.

[0075] In an embodiment where the first adjustment condition includes that the ratio between the first number and the second number is greater than or equal to the first threshold, the first number of passengers whose gaze duration in the target statistical period reaches the first set duration and the second number of passengers whose gaze duration in the target statistical period reaches the first set duration can be determined by analyzing the gaze direction of the passenger in the passenger image data. The duration of gaze at the target display area can be the duration of continuous gaze at the target display area or the cumulative duration of gaze at the target display area; the duration of gaze at the display device can be the duration of continuous gaze at the display device or the cumulative duration of gaze at the display device.

[0076] In an embodiment where the first adjustment condition includes a ratio between the third number and the fourth number being greater than or equal to a second threshold, the third number of passengers who gaze at the target display area with a set eye state during the target statistical period and the fourth number of passengers who gaze at the display device with a set eye state during the target statistical period can be determined by analyzing the eye state of the passengers in the passenger image data.

[0077] In one example, the set eye state may be a squinting state.

[0078] In the embodiments of the present disclosure, the duration of the target statistical period may be pre-set according to the application scenario or specific requirements. For example, the duration of the target statistical period may be 1 hour or 10 minutes.

[0079] Furthermore, the target statistical period may be any statistical period in a day, or a statistical period other than a peak period in a day, or a period of time before the current time.

[0080] In the embodiment where the first adjustment condition includes that the voice of the passenger contains a keyword corresponding to the target display area, it may be determined by analyzing the passenger voice data whether the voice of the passenger contains any keyword corresponding to the target display area. Specifically, corresponding keywords may be set in advance for at least one display area according to the display content. For example, keywords corresponding to display area A may include emergency, notification, etc.; keywords corresponding to display area B may include arrival, time, a few minutes, next stop, etc.; keywords corresponding to display area C may include advertisement, etc.

[0081] Step S3220: When the target display area meets the first adjustment condition, the display parameter of the target display area is adjusted to a second parameter value.

[0082] In this embodiment, when the target display area meets any one of the first adjustment conditions, the display parameter of the target display area is adjusted to the second parameter value.

[0083] In this embodiment, the second parameter value may be greater than or equal to the parameter value of the display parameter before adjustment.

[0084] This implementation adjusts the display parameters of the target display area to the second parameter value, so that passengers can capture the information they are concerned about more quickly and improve their riding experience.

[0085] In one embodiment of the present disclosure, the second parameter value may be pre-set according to an application scenario or specific requirements.

[0086] For example, when the display parameters include the font size of the displayed text, adjusting the display parameters of the target display area means increasing the font size of the text displayed in the target display area.

[0087] For another example, when the display parameters include contrast, adjusting the display parameters of the target display area means increasing the contrast of the target display area.

[0088] For another example, when the display parameters include backlight brightness, adjusting the display parameters of the target display area means increasing the backlight brightness of the target display area.

[0089] For another example, when the display parameters include length and / or width, adjusting the display parameters of the target display area means increasing the length and / or width of the target display area and increasing the content displayed in the target area.

[0090] In the case where the target display area includes the A display area and the B display area, and the display parameters include the length and / or width, the adjusted display template may be as follows: Figure 4 shown.

[0091] In another embodiment of the present disclosure, the parameter value of the corresponding display parameter may be adjusted by setting a step size so that the parameter value of the display parameter is adjusted to the second parameter value.

[0092] The setting step sizes corresponding to different display parameters may be the same or different, which is not limited here.

[0093] Specifically, adjusting the display parameter of the target display area to the second parameter value may be to increase the parameter value of any display parameter by a corresponding set step length so that the parameter value of the display parameter becomes the second parameter value.

[0094] In one embodiment of the present disclosure, the method may further include: determining the age distribution of passengers gazing at the target display area according to the passenger image data; and determining the second parameter value according to the age distribution.

[0095] In this embodiment, at least one age group can be set in advance according to the application scenario or specific needs. For example, at least one age group may include an age group of 40-50 years old, an age group of 50-60 years old, an age group of 60-70 years old, an age group of over 70 years old, etc.

[0096] Furthermore, the age distribution may represent the proportion of passengers of each age group among the passengers gazing at the target display area.

[0097] In one example, the second parameter value is determined according to the age distribution, and the age group with the largest proportion among the passengers gazing at the target display area is determined as the target age group, and the second parameter value is determined according to the target age group.

[0098] In this embodiment, first mapping data reflecting the mapping relationship between age groups and parameter values ​​of any display parameter can be pre-set; based on the target age group and the first mapping data, the parameter value of the display parameter corresponding to the target age group is obtained as the second parameter value of the display parameter.

[0099] The first mapping data may be a first mapping function, or a first comparison table, etc., which is not limited here.

[0100] For the first mapping function, the dependent variable of the first mapping function is the parameter value of the display parameter, and the independent variable is the age group. In this way, by substituting the target age group into the first mapping function, the parameter value of the display parameter corresponding to the target age group can be obtained as the second parameter value of the display parameter.

[0101] For the first comparison table, the parameter value of the display parameter corresponding to the target age group can be found in the first comparison table as the second parameter value of the display parameter. If the target age group cannot be directly found in the first comparison table, two values ​​adjacent to the target age group can be found, and based on the two values ​​and the parameter values ​​of the display parameter corresponding to the two values, the parameter value of the display parameter corresponding to the target age group can be obtained by interpolation as the second parameter value of the display parameter.

[0102] In this embodiment, the older the target age group is, the larger the second parameter value is.

[0103] Through this embodiment, the display parameters of the target display area are adjusted in combination with the age distribution of passengers gazing at the target display area. When the age of the passengers gazing at the target display area is older, the display parameters of the target display area can be further increased so that the older passengers can quickly capture the information they are concerned about, thereby improving the passengers' viewing experience.

[0104] In one embodiment of the present disclosure, the method further includes: determining at least one of the first threshold, the second threshold, and the first set time duration according to the age distribution of passengers gazing at the target display area.

[0105] In this embodiment, the older the target age group is, the smaller the first threshold, the second threshold and the first set time length are.

[0106] In one embodiment, second mapping data reflecting the mapping relationship between the age group and the first threshold may be preset; and the first threshold corresponding to the target age group is obtained according to the target age group and the second mapping data.

[0107] The second mapping data may be a second mapping function, or a second comparison table, etc., which is not limited here.

[0108] For the second mapping function, the dependent variable of the second mapping function is the first threshold value, and the independent variable is the age group. Thus, by substituting the target age group into the second mapping function, the first threshold value corresponding to the target age group can be obtained.

[0109] For the second comparison table, the first threshold corresponding to the target age group can be found in the second comparison table. If the target age group cannot be directly found in the second comparison table, two values ​​adjacent to the target age group can be found, and the first threshold corresponding to the target age group can be obtained by interpolation based on the two values ​​and the first thresholds corresponding to the two values.

[0110] In one embodiment, third mapping data reflecting the mapping relationship between the age group and the second threshold value may be preset; and the second threshold value corresponding to the target age group may be obtained according to the target age group and the third mapping data.

[0111] The third mapping data may be a third mapping function, or a third comparison table, etc., which is not limited here.

[0112] For the third mapping function, the dependent variable of the third mapping function is the second threshold value, and the independent variable is the age group. Thus, by substituting the target age group into the third mapping function, the second threshold value corresponding to the target age group can be obtained.

[0113] For the third comparison table, the second threshold corresponding to the target age group can be found in the third comparison table. If the target age group cannot be directly found in the third comparison table, two values ​​adjacent to the target age group can be found, and the second threshold corresponding to the target age group can be obtained by interpolation according to the two values ​​and the second thresholds corresponding to the two values.

[0114] In one embodiment, fourth mapping data reflecting the mapping relationship between the age group and the first set time may be preset; and the first set time corresponding to the target age group is obtained according to the target age group and the fourth mapping data.

[0115] The fourth mapping data may be a fourth mapping function, or a fourth comparison table, etc., which is not limited here.

[0116] For the fourth mapping function, the dependent variable of the fourth mapping function is the first set time, and the independent variable is the age group. Thus, by substituting the target age group into the fourth mapping function, the first set time corresponding to the target age group can be obtained.

[0117] For the fourth comparison table, the first set time corresponding to the target age group can be found in the fourth comparison table. If the target age group cannot be directly found in the fourth comparison table, two values ​​adjacent to the target age group can be found, and the first set time corresponding to the target age group can be obtained by interpolation according to the two values ​​and the first set times corresponding to the two values.

[0118] Through this embodiment, at least one of the first threshold, the second threshold, and the first set time is adjusted in combination with the age distribution of passengers gazing at the target display area. When the age of the passengers gazing at the target display area is older, the display parameters of the target display area can be increased in time, so that the older passengers can quickly capture the information they are concerned about, thereby improving the passengers' viewing experience.

[0119] In one embodiment of the present disclosure, after adjusting the display parameters corresponding to the target display area to the second parameter value, the method further includes: determining whether the target display area of ​​the display device meets the second adjustment condition based on the behavior data; if the target display area meets the second adjustment condition, adjusting the display parameters corresponding to the target display area to the first parameter value.

[0120] In this embodiment, the first parameter value may be less than or equal to the parameter value of the display parameter before adjustment.

[0121] In one embodiment of the present disclosure, the second adjustment condition includes at least one of the following:

[0122] The time duration during which the display parameter of the target display area is adjusted to the second parameter value is greater than or equal to the second set time duration;

[0123] The ratio between the first number and the second number is less than or equal to a third threshold value; wherein the first number is the number of passengers whose gaze time of the target display area reaches a first set time, and the second number is the number of passengers whose gaze time of the display device reaches the first set time;

[0124] The ratio between the third number and the fourth number is less than or equal to a fourth threshold; wherein the third number is the number of passengers who gaze at the target display area with a set eye state, and the fourth number is the number of passengers who gaze at the display device with a set eye state.

[0125] In this embodiment, the third threshold and the fourth threshold can be set based on application scenarios or specific requirements. The third threshold and the fourth threshold can be equal or different, which is not limited here. For example, the third threshold and the fourth threshold can both be 0.3.

[0126] Furthermore, the third threshold may be smaller than the first threshold, and the second threshold may be smaller than the fourth threshold.

[0127] Furthermore, the second set duration may be set based on an application scenario or specific requirements. For example, the second set duration may be 30 minutes.

[0128] In an embodiment in which the second adjustment condition includes that the time length during which the display parameter of the target display area is adjusted to the second parameter value is greater than or equal to the second set time length, it can be determined that the target display area satisfies the second adjustment condition when the time length during which the display parameter is adjusted to the second parameter value is greater than or equal to the second set time length and the display parameter is not adjusted again during this process.

[0129] In an embodiment where the second adjustment condition includes that the ratio between the first number and the second number is less than or equal to the third threshold, the first number of passengers whose gaze duration of the target display area reaches the first set duration in the target statistical period and the second number of passengers whose gaze duration of the display device reaches the first set duration in the target statistical period can be determined by analyzing the gaze direction of the passenger in the passenger image data. The duration of gaze at the target display area can be the duration of continuous gaze at the target display area or the cumulative duration of gaze at the target display area; the duration of gaze at the display device can be the duration of continuous gaze at the display device or the cumulative duration of gaze at the display device.

[0130] In an embodiment in which the second adjustment condition includes a ratio between the third number and the fourth number being less than or equal to a fourth threshold, the third number of passengers who gaze at the target display area with a set eye state during the target statistical period and the fourth number of passengers who gaze at the display device with a set eye state during the target statistical period can be determined by analyzing the eye state of the passengers in the passenger image data.

[0131] In the embodiments of the present disclosure, the duration of the target statistical period may be pre-set according to the application scenario or specific requirements. For example, the duration of the target statistical period may be 1 hour or 10 minutes.

[0132] Furthermore, the target statistical period may be any statistical period in a day, or a statistical period other than a peak period in a day, or a period of time before the current time.

[0133] Through this embodiment, when the target display area meets the second adjustment condition, the display parameter corresponding to the target display area can be adjusted to the first parameter value, thereby avoiding infinite increase of the display parameter value of the target display area and affecting the display effect of the display device.
