[0067] Various exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. Although the example methods and apparatus described below include software and / or firmware executed on hardware among other components, it should be noted that these examples are merely illustrative and should not be considered as limiting. For example, it is contemplated that any or all of the hardware, software, and firmware components could be embodied exclusively in hardware, exclusively in software, or in any combination of hardware and software. Thus, while the following has described exemplary methods and apparatus, those skilled in the art will readily appreciate that the examples provided are not intended to limit the manner in which such methods and apparatus may be implemented.
[0068] In addition, the flowchart and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of methods and systems according to various embodiments of the present disclosure. It should be noted that the functions noted in the blocks may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the flowcharts and / or block diagrams, and combinations of blocks in the flowcharts and / or block diagrams, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
[0069] The terms “including” , “comprising” and similar terms used in the present disclosure are open terms, that is, “including / comprising but not limited to” , which means that other contents may also be included. The term “based on” means “based at least in part on” . The term “an embodiment” means “at least one embodiment” ; the term “another embodiment” means “at least one additional embodiment” ; etc.
[0070] In the present disclosure, terms such as “first” and “second” are not used to limit the sequence and the number of components, unless otherwise specified.
[0071] In the present disclosure, the orientation or positional relationship indicated by the terms “upper” , “lower” , “front” , “rear” , “left” , “right” , “inner” , “outer” and the like is merely for convenience and simplicity of description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation to the present disclosure.
[0072] In the present disclosure, the term “display region” refers to a region having a display function, which can play a role of display when needed. However, it does not mean that each of these display regions must display corresponding content, but it is determined according to the actual application situation that the corresponding content is displayed when the display region needs to display, and the display region is not used for displaying when it does not need to display.
[0073] In the present disclosure, the term “visual comfort” refers to the comfort or ease of viewing the information displayed on the sidelite glass when the occupant is seated in the seat. When viewing the information displayed on the sidelite glass, if the occupant does not need to deliberately adjust the posture, rotate the body or the head, or adjusts the posture, rotates the body or the head to a smaller extent, less attention or energy is consumed, and it is easier for the occupant to view the information, and the visual comfort is correspondingly higher. On the contrary, if the occupant does not easily view the information, and needs to deliberately or greatly adjust the posture, rotate the body or the head to view the information, some attention or energy needs to be consumed, and the visual comfort is lower.
[0074] Hereinafter, the sidelite glass of a vehicle is taken as an example for description, but the means of transportation may also be any other means of transportation such as a ship, a subway, an airplane, or a train. In addition, it should be understood that, for the vehicle, the sidelite glass may be a sidelite glass located beside the driving seat or the co-pilot seat, or may be a sidelite glass located beside the rear seats.
[0075] As described above, the vehicle information display solution in the prior arts does not consider a line-of-sight direction of an observer (such as an occupant) . Therefore, when these solutions are directly applied to a sidelite glass of a vehicle, in order to view information, an observer may need to deliberately adjust a posture and greatly rotate his body or head, resulting in that the observer needs to consume a certain amount of attention to process the information, which adds unnecessary trouble to them and reduces comfort during their journey. In view of such a technical situation and corresponding technical problems, the solution of the present disclosure associates the target display region with the visual comfort of the occupant, so that the occupant can more comfortably view the information on the sidelite glass when sitting beside the sidelite glass, thereby reducing the consumed attention and improving the comfort and user experience during the journey of the occupant.
[0076] The technical solutions according to the present disclosure will be described in detail below according to several embodiments, and a display control method for a sidelite glass of a means of transportation according to an embodiment of the present disclosure is first introduced.
[0077] Referring first to FIG. 1, FIG. 1 shows a flowchart of a display control method for a sidelite glass of a means of transportation according to an embodiment of the present disclosure. The display control method 100 may be performed by any computing device, such as an independent control device, a system host of a vehicle, or a control device included in a sidelite glass assembly. The vehicle may be, for example, various types of vehicles such as a ride-hailing vehicle, a private vehicle, a taxi, a shared vehicle, and a driverless vehicle.
[0078] In step 101, content to be displayed is acquired. The content to be displayed may include various information to be displayed on the sidelite glass, for example, information related to the occupant’s journey, information related to function control, information related to audio-visual entertainment, communication information and / or life service information, etc. The information related to the occupant’s journey may include a greeting message, a vehicle position, a map, navigation information, environmental information, and the like; the information related to the function control may include a content selection menu, a function control panel (for example, including switches such as seat adjustment, seat heating, air conditioning adjustment, and window control) , and the like; the information related to the audio-visual entertainment may include a game, a short video, a music player, a photo, and the like; the communication information may include a short message, a chat software interface, and the like; and the life service information may include a dressing index, dining and accommodation information, travel information, and the like related to the destination. For the occupant seated beside the sidelite glass, he / she does not need to pay attention to the details of the map and the navigation information like the driver, so the map and the navigation information to be displayed on the sidelite glass can briefly present the departure place, the destination, and the vehicle travel route. The environmental information may include weather forecast information of the destination, real-time weather information of a current location of the vehicle, real-time environmental parameters in the vehicle, and the like. The weather forecast information may include changes of such as air temperature, humidity, wind speed, air quality, and air pressure upon arrival at the destination or within a certain period of time in the future at the destination (for example, the duration of the occupant staying at the destination) . The real-time weather information may include real-time air temperature, humidity, wind speed, air quality, air pressure, etc. The real-time environmental parameters may include temperature, humidity, air quality, light, odor, sound, etc. sensed by sensors within the vehicle. Of course, in addition to the information listed above, the content to be displayed may include any other suitable information. It should be noted that, when the occupant is not the driver, she / he usually does not pay much attention to information of the vehicle itself (for example, the vehicle speed, vehicle fault information, and driving assistance information) , and therefore, in order to avoid overly complex information, the content to be displayed on the sidelite glass may not include these information.
[0079] The above information may be acquired from an internal or external memory storing the information, or may be received from other devices, or may be input by an occupant within the vehicle. For example, if information related to function control and information related to audio-visual entertainment are stored in a memory of a system host of a vehicle, the information may be directly read from the memory; during a vehicle travel, a vehicle location, a map, and navigation information are received from a navigation positioning module of the vehicle; weather forecast information of the destination is acquired from the Internet via a vehicle-mounted networking device (such as T-BOX) , real-time weather information of a current location of the vehicle sensed in real time is received from an environmental sensor (such as a temperature sensor, a humidity sensor, an air quality sensor, etc. ) installed outside the vehicle, and real-time environmental parameters in the vehicle sensed in real time are received from an environmental sensor (such as a temperature sensor, a humidity sensor, an illumination sensor, an air quality sensor, etc. ) installed in the vehicle; dining and accommodation information and travel information related to the destination are acquired from the Internet via a vehicle-mounted networking device; and content that an occupant desires to be displayed on a sidelite glass, such as the interface of one or more applications running on a user device (such as a mobile phone, a tablet computer, a bracelet, etc. ) of the occupant, is received from the user device via a communication module (such as a Bluetooth module, a WIFI module, a 4G module, a 5G module, etc. ) .
[0080] In step 102, the corresponding content is displayed in the target display region on the sidelite glass. The target display region is divided according to visual comfort of an occupant within the means of transportation. The target display region may be a display region pre-divided on the sidelite glass, or may be one of at least two display regions pre-divided, or may be a display region that is individually divided for a specific occupant. The visual comfort of the occupant may be determined by modeling calculation or scientific experiments based on ergonomics. It can be understood that the higher the gaze frequency or the longer the gaze duration of the occupant at a certain position on the sidelite glass, the higher the visual comfort of the occupant. Therefore, in an example, statistics and analysis may be performed on gaze frequencies and / or gaze durations of a plurality of occupants at a plurality of positions on the sidelite glass, to determine visual comfort of different positions on the sidelite glass for the plurality of occupants, and then one or more display regions are divided on the sidelite glass in combination with a display area required by the content to be displayed and a total area of the sidelite glass. The plurality of occupants may be adults. In addition, visual comfort of different positions on the sidelite glass for a plurality of children may be determined in the same manner for the plurality of children. In another example, statistics and analysis may be performed on gaze frequencies and / or gaze durations of a specific occupant at a plurality of positions on the sidelite glass, to determine visual comfort of different positions on the sidelite glass for the specific occupant, so as to determine a most suitable display region for the specific occupant, to perform personalized display region division, and to be stored as configuration data in, for example, a host system of the vehicle. After the occupant is on board, the configuration data can be automatically selected by the computing device executing the display control method 100 based on image recognition techniques or manually selected by the specific occupant. It should be noted that the sidelite glass used in the above scientific experiments is not necessarily the sidelite glass finally mounted on the vehicle, which may be a sample of a certain model of sidelite glass; the above scientific experiments are not necessarily performed after the sidelite glass is mounted on the vehicle, which may be completed in a laboratory environment. After the sidelite glasses of this model are installed in batches on a batch of vehicles, the statistical and analytical results and the division of the display regions obtained in the above scientific experiments are applicable to all of these sidelite glasses. In addition, after one or more display regions are divided, the positions of the display regions in the vertical direction may be further adjusted according to the height data or eyeball height data of the occupant, and then stored as configuration data in the host system of the vehicle for subsequent use. Corresponding contents may be displayed in more than one display region respectively at the same time. The displayed contents may be independent of each other or associated with each other. For example, a function control panel is displayed in one display region, and information related to audio-visual entertainment is displayed in another display region; or the size of the target display region is adjusted to include one or more other display regions, that is, two or more display regions are merged into one display region for display.
[0081] The visual comfort of the occupant depends on the position of the display region. When the seat is set to face toward or away from the moving direction of the vehicle, the seating direction of the occupant is substantially parallel to the sidelite glass, and the line-of-sight direction in his / her natural seating state (i.e., without deliberately adjusting the sitting posture, turning the body or head) is also substantially parallel to the sidelite glass. In the natural seating state, it is easier for the occupant to notice an obliquely forward region, that is, a region on the sidelite glass that is located within the field of view of the occupant and is relatively far away from the occupant. On the contrary, it is less easy for the occupant to see a region beside or behind, that is, a region on the sidelite glass that is relatively close to the occupant or a region that is not within the field of view of the occupant, and if contents are displayed on these regions, the occupant needs to turn his / her head or even his / her upper part of the body to view these contents.
[0082] The target display region may be, but is not necessarily, a region with optimal visual comfort for the occupant. In some cases, if the display region with optimal visual comfort has been used to display other content, other region needs to be selected as the target display region. For example, a display region with the second optimal visual comfort may be selected as the target display region. In some other cases, each category of content corresponds to one display region, and therefore a display region corresponding to the category of content to be displayed is not necessarily a region with optimal visual comfort. In some other cases, only one display region is pre-divided, which is a region with optimal visual comfort level on the sidelite glass, and the display region may be directly used as the target display region.
[0083] Several embodiments are listed below to illustrate possible positions and sizes of the target display region on the sidelite glass. FIG. 2 shows a display region division solution of a sidelite glass according to an embodiment of the present disclosure. The display regions may be pre-divided and programmed in a projector or a display chip, and corresponding contents are projected or displayed in these display regions under the control of the projector or the display chip. The sidelite glass 200 may be a sidelite glass located beside a driving seat or a co-pilot seat of the vehicle, or may be a sidelite glass located beside a rear seat.
[0084] As can be seen from FIG. 2, the direction indicated by the arrow is the moving direction of the vehicle, and a seat is provided close to the sidelite glass 200, which is provided toward the moving direction of the vehicle. Therefore, when the occupant is seated in the seat, his / her line-of-sight direction also faces the moving direction of the vehicle, and is substantially parallel to the sidelite glass 200. It can be understood that the viewing angle of FIG. 2 is the viewing angle observing the sidelite glass 200 from the inside of the vehicle, and the sidelite glass 200 is the sidelite glass on the right side of the vehicle (such as beside the co-pilot seat and the rear seat thereof) . For the sidelite glass on the left side of the vehicle (such as beside the driving seat and the rear seat thereof) , the division of the display regions is mirrored to that in FIG. 2. The sidelite glass 200 has a first side 21 substantially located in the vertical direction, a second side 22 opposite to the first side 21, and an upper edge 23 and a lower edge 24 substantially located in the horizontal direction. The first side 21 is a side toward which the occupant's face is facing when the occupant is seated in the seat, and in this embodiment, is a side of the sidelite glass 200 closer to the head of the vehicle. The sidelite glass 200 includes a central region 201, a first corner region 202 between the first side 21 and the upper edge 23, a second corner region 203 between the first side 21 and the lower edge 24, a third corner region 204 between the second side 22 and the lower edge 24, and a fourth corner region 205 between the second side 22 and the upper edge 23. The visual comfort of these regions for the occupant may be predetermined. In this embodiment, a plurality of occupants are respectively seated in the seat, and contents of the same feature are displayed in the five regions at the same time, that is, the display size, display form and display duration are the same. The number of occupants may be set as required, for example, 20 or more, 30 or more, 40 or more, 50 or more, etc. The gaze frequencies and the gaze durations of these occupants on these five regions on the sidelite glass are perfomed statistics through an eye tracker, and then the statistical results are analyzed. For these five regions, the gaze frequencies of these occupants on the first corner region 202, the second corner region 203, the central region 201, the third corner region 204, and the fourth corner region 205 decrease sequentially, and the gaze durations decrease sequentially. Accordingly, it may be determined that visual comfort for the occupants of the first corner region 202, the second corner region 203, the central region 201, the third corner region 204, and the fourth corner region 205 decreases sequentially.
[0085] In this embodiment, the entire sidelite glass 200 is divided into a first region 206, a second region 207 and a third region 208. The first region 206 includes the first corner region 202. The second region 207 is adjacent to the first region 206 and includes the central region 201 and the second corner region 203. The third region 208 includes the third corner region 204 and the fourth corner region 205, which is also the region on the sidelite glass 200 other than the first region 206 and the second region 207. The average values of the gaze frequencies and / or the gaze durations of the first region 206, the second region 207, and the third region 208 may be calculated to rank the visual comfort of the first region 206, the second region 207, and the third region 208. Specifically, the first region 206 includes only the first corner region 202, so the average value of the gaze frequency and / or the gaze duration of the first region 206 is the gaze frequency and / or the gaze duration of the first corner region 202; the second region 207 includes the central region 201 and the second corner region 203, so the average value of the gaze frequencies and / or the gaze durations of the central region 201 and the second corner region 203 can be calculated; and the third region 208 includes the third corner region 204 and the fourth corner region 205, so the average value of the gaze frequencies and / or the gaze durations of the third corner region 204 and the fourth corner region 205 can be calculated. Finally, the first region 206, the second region 207, and the third region 208 are ranked according to the above average values, and it can be obtained that the first region 206 has better visual comfort than the second region 207, and the second region 207 has better visual comfort than the third region 208. It can be understood that, in other embodiments, the visual comfort ranking may be performed for the first region 206, the second region 207, and the third region 208 according to other criteria. For example, ranking is performed according to the highest visual comfort of one or more positions included in each region. Specifically, the first region 206 includes only the first corner region 202, so the highest visual comfort for the first region 206 is the visual comfort of the first corner region 202; the second region 207 includes the central region 201 and the second corner region 203, so the highest visual comfort for the second region 207 is the visual comfort of the second corner region 203; and the third region 208 includes the third corner region 204 and the fourth corner region 205, so the highest visual comfort for the third region 208 is the visual comfort of the third corner region 204. Finally, the first region 206, the second region 207, and the third region 208 are ranked according to the highest visual comfort for the above regions, and it can also be obtained that the first region 206 has better visual comfort than the second region 207, and the second region 207 has better visual comfort than the third region 208. In addition, it can also be understood that in other embodiments, other forms of division may also be adopted according to actual applications. For example, the first region 206 includes the first corner region 202 and the second corner region 203, the second region 207 includes the central region 201, the third region 208 includes the third corner region 204 and the fourth corner region 205; the first region 206 includes the first corner region 202, the second region 207 includes the central region 201, the third region 208 includes the third corner region 204 and the fourth corner region 205; the first region 206 includes the first corner region 202, the second region 207 includes the second corner region 203, the third region 208 includes the central region 201, the third corner region 204 and the fourth corner region 205, and so on. The sizes of the first region 206, the second region 207 and the third region 208 may be predetermined according to the area of the sidelite glass and the display area required by the content to be displayed, or may be adjusted according to the display area required by the content to be displayed.
[0086] In some embodiments, the first region 206 and the second region 207 are display regions, and the third region 208 is a non-display region. Since the occupant is relatively less comfortable when viewing the region below the line-of-sight, it is possible to divide between the first region 206, the second region 207 and the third region 208 by using an arc. However, it should be understood that division by using an arc is merely an example, and in other embodiments, division may be performed by using a line such as an oblique line or a curve. Moreover, the arc merely indicates the boundary between the first region 206, the second region 207, and the third region 208, and it does not mean that when the content is displayed in the first region 206 and / or the second region 207, the entire first region 206 and / or the entire second region 207 needs to be filled. For example, content may be displayed in a middle portion of the first region 206 and / or the second region 207. Content may also be displayed in the entire first region 206 and / or the entire second region 207 as needed (e.g., when a movie or video is played) . Which of the first region 206 and the second region 207 being used as the target display region may be determined according to the category of the content to be displayed. In addition, the contents in the first region 206 and the second region 207 may be displayed in a certain order. For example, a function control panel is first displayed in the first region 206, including several options such as a map, audio-visual entertainment, and life services. Then, in response to the occupant's selection of a function in the function control panel, information related to the selected function in the function control panel (such as the specific content of the audio-visual entertainment information) is displayed in the second region 207. In this way, the display regions can be divided and different contents can be displayed according to the levels of the visual comfort of the occupant, so that the display level is clearer and more user-friendly.
[0087] In some embodiments, the size of one or more of the first region 206, the second region 207, and the third region 208 may be adjusted. The first region 206 and the second region 207 are display regions, and the third region 208 may be a display region or a non-display region. The adjustment may be expansion or contraction. For example, the first region 206 may expand rightward into the second region 207 or to the right boundary of the second region 207, or may expand rightward into the third region 208 or to the right boundary of the third region 208 (i.e., the second side 22 of the sidelite glass 200) ; the second region 207 may expand leftward into the first region 206 or to the left boundary of the first region 206 (i.e., the first side 21 of the sidelite glass 200) , or may expand rightward into the third region 208 or to the right boundary of the third region 208. Of course, the second region 207 may expand leftward and rightward simultaneously. When the third region 208 is a display region, the third region 208 may expand leftward into the second region 207 or to the left boundary of the second region 207, or may expand leftward into the first region 206 or to the left boundary of the first region 206 (i.e., the first side 21 of the sidelite glass 200) . The size of the region may be adjusted according to the display area required by the content to be displayed or when the category of the content to be displayed belongs to one of the specific one or more categories. For example, the specific one or more categories include information related to audio-visual entertainment. When the content to be displayed is information related to audio-visual entertainment (such as a movie or a video) , the target display region is the second region 207 corresponding to this category. Since this category belongs to one of the specific one or more categories, the second region 207 is expanded leftward into the first region 206 or to the left boundary thereof, and the above-mentioned information related to audio-visual entertainment is displayed therein, that is, the content is continuously displayed in the first region 206 and the second region 207. In this way, the flexibility of sidelite glass display can be increased, and the user experience can be further improved.
[0088] Although in the division solution of FIG. 2, two display regions adjacent to each other are divided, it should be understood that in other embodiments, more display regions may also be divided on the sidelite glass according to actual applications, and these display regions may be adjacent or spaced apart. In addition, it can be understood that the selection and the adjustment of the size of the target display region are both performed by the system, and if the system receives a selection instruction or a size adjustment instruction of the occupant with respect to the target display region, the priority thereof is higher than the selection or adjustment of the system.
[0089] FIG. 3 shows another display region division solution of a sidelite glass according to an embodiment of the present disclosure. Similarly, the display regions may be pre-divided and programmed in the projector or the display chip, and corresponding contents are projected or displayed in these display regions under the control of the projector or the display chip. The sidelite glass 300 may be a sidelite glass beside a driving seat or a co-pilot seat of the vehicle, or may be a sidelite glass beside a rear seat.
[0090] Compared with the region division solution of FIG. 2, FIG. 3 divides the sidelite glass 300 into two regions, a first region 306 and a second region 307. Similar to FIG. 2, the direction indicated by the arrow is the moving direction of the vehicle, and a seat is provided close to the sidelite glass 300, which is provided toward the moving direction of the vehicle. Therefore, when the occupant is seated in the seat, the line-of-sight direction also faces the moving direction of the vehicle, and is substantially parallel to the sidelite glass 300. The viewing angle of FIG. 3 is also the viewing angle observing the sidelite glass 300 from the inside of the vehicle, and the sidelite glass 300 is the sidelite glass on the right side of the vehicle (such as beside the co-pilot seat and the rear seat thereof) . For the sidelite glass on the left side (such as beside the driving seat and the rear seat thereof) of the vehicle, the division of the regions is mirrored to that in FIG. 3. The sidelite glass 300 has a first side 31 substantially located in the vertical direction, a second side 32 opposite to the first side 31, and an upper edge 33 and a lower edge 34 substantially located in the horizontal direction. The first side 31 is a side towards which the occupant's face is facing when the occupant is seated in the seat, and in this embodiment, is a side of the sidelite glass 300 closer to the head of the vehicle. The sidelite glass 300 includes a central region 301, a first corner region 302 between the first side 21 and the upper edge 33, a second corner region 303 between the first side 31 and the lower edge 34, a third corner region 304 between the second side 32 and the lower edge 34, and a fourth corner region 305 between the second side 32 and the upper edge 33. In the manner described with reference to FIG. 2, statistics and analysis may be performed on gaze frequencies and / or gaze durations of a plurality of occupants at these positions when seated in the seat, so as to determine that the visual comfort for the occupants of the first corner region 302, the second corner region 303, the central region 301, the third corner region 304, and the fourth corner region 305 decreases sequentially.
[0091] In this embodiment, the first region 306 includes the central region 301, the first corner region 302, and the second corner region 303. The second region 307 is adjacent to the first region 306, and includes the third corner region 304 and the fourth corner region 305, which is also the region on the sidelite glass 300 other than the first region 306. For an occupant, the first region 306 has better visual comfort than the second region 307. It can be understood that, in other embodiments, other forms of division may also be used according to actual applications. For example, the first region 306 includes the first corner region 302, and the second region 307 includes any one or more of the central region 301, the second corner region 303, the third corner region 304, and the fourth corner region 305; the first region 306 includes the first corner region 302 and the second corner region 303, and the second region 307 includes any one or more of the central region 301, the third corner region 304, and the fourth corner region 305; the first region 306 includes the central region 301 and the first corner region 302, and the second region 307 includes any one or more of the second corner region 303, the third corner region 304, and the fourth corner region 305; the first region 306 includes the central region 301, the first corner region 302, and the second corner region 303, and the second region 307 includes the third corner region 304 or the fourth corner region 305, and so on. The sizes of the first region 306 and the second region 307 may be predetermined according to the area of the sidelite glass and the display area required by the content to be displayed, or may be adjusted according to the display area required by the content to be displayed before displaying.
[0092] In some embodiments, the first region 306 is a display region, and the second region 307 is a non-display region. An arc division manner is used between the first region 306 and the second region 307. However, it should be understood that division by using an arc is merely an example, and in other embodiments, division may be performed by using a line such as an oblique line or a curve. Moreover, the arc merely indicates the boundary between the first region 306 and the second region 307, and it does not mean that the entire first region 306 needs to be filled when the content is displayed in the first region 306. For example, content may be displayed in a middle portion of the first region 306. If necessary, content may also be displayed in the entire first region 306 (for example, when a movie or a video is played) . In addition, because only the first region 306 is a display region, the first region 301 is used as the target display region, and all of the content to be displayed is displayed in the first region 306.
[0093] In some embodiments, the size of the first region 306 and / or the second region 307 may be adjusted. The first region 306 is a display region, and the second region 307 may be a display region or a non-display region. The adjustment may be expansion or contraction. For example, the first region 306 may expand rightward into the second region 307 or to the right boundary of the second region 307 (i.e., the second side 32 of the sidelite glass 300) . When the second region 307 is a display region, the second region 307 may expand leftward into the first region 306 or to the left boundary of the first region 306 (i.e., the first side 31 of the sidelite glass 300) . The size of the region may be adjusted according to the display area required by the content to be displayed or when the category of the content to be displayed belongs to one of the specific one or more categories. For example, the specific one or more categories include information related to audio-visual entertainment. When the content to be displayed is information related to audio-visual entertainment (such as a movie or a video) , the target display region is the second region 307 corresponding to this category. Since this category belongs to one of the specific one or more categories, the second region 307 is expanded leftward into the first region 306 or to the left boundary thereof, and the above-mentioned information related to audio-visual entertainment is displayed therein, that is, the content is continuously displayed in the first region 306 and the second region 307. In this way, the flexibility of sidelite glass display can be increased, and the user experience can be further improved.
[0094] In addition, it can be understood that the selection and the adjustment of the size of the target display region are both performed by the system, and if the system receives a selection instruction or a size adjustment instruction of the occupant with respect to the target display region, the priority thereof is higher than the selection or adjustment of the system.
[0095] Compared with the existing in-vehicle information display method, the display control method for the sidelite glass of the means of transportation provided by the above embodiment associates the target display region with the visual comfort of the occupant, so that the occupant can view the information on the sidelite glass more comfortably when sitting beside the sidelite glass, thereby reducing the attention consumed by the occupant and improving the comfort and user experience during the journey of the occupant.
[0096] In some embodiments, after step 101, the display control method 100 further includes: determining a target display region on the sidelite glass based on the content to be displayed. That is, the target display region may not be fixed, instead, its position is determined before displaying the content. The position of the target display region may be determined according to the category of the content to be displayed. For example, if the content to be displayed is information that is relatively important for the occupant’s journey, such as information related to the occupant’s journey and information related to function control, the information may be displayed in a region with optimal visual comfort for the occupant. For another example, if the content to be displayed is information less important to the occupant’s journey, such as information related to audio-visual entertainment and life service information, the information may be displayed in a region with good or ordinary visual comfort for the occupant, and the size of the display region may also be adjusted according to the display area required by the content to be displayed. In this way, the position and / or size of the target display region may be flexibly determined as needed, thereby further increasing the flexibility of the sidelite glass display.
[0097] In some embodiments, the sidelite glass includes at least two display regions pre-divided according to the visual comfort of the occupant. Content of each category may be corresponding to one of the at least two display regions in advance, and then the target display region is selected by determining the category of the content. For example, in the division solution of FIG. 2, the information related to the occupant’s journey and the information related to the function control are corresponding to the first region 206 in advance, and the information related to the audio-visual entertainment, the communication information and the life service information are corresponding to the second region 207 in advance. In these embodiments, the step of determining the target display region on the sidelite glass based on the content to be displayed further includes: determining a category of the content to be displayed; and determining a single display region corresponding to the determined category in the at least two display regions as the target display region. In this way, the content to be displayed may be displayed in different regions on the sidelite glass according to the category (for example, the importance degree corresponding to the category) of the content to be displayed.
[0098] In some embodiments, the sidelite glass includes at least two display regions pre-divided according to the visual comfort of the occupant. At least one of the display regions may be corresponding to a plurality of categories of contents in advance, and the corresponding display region is determined by determining the category of the content. When other content has been displayed in the corresponding display region, it is determined that whether the remaining display area of the corresponding display region is sufficient to display the content to be displayed. If the remaining display area is sufficient to display the content to be displayed, the content to be displayed is displayed in the corresponding display region. Otherwise, other available display regions in the at least two display regions are selected, for example, an available display region with a lower visual comfort than the corresponding display region in the at least two display regions is selected, and the content to be displayed is displayed in the selected available display region, or a part of the content to be displayed may be displayed in the corresponding display region, and another part of the content to be displayed is displayed in the selected available display region. When no other content is displayed in the corresponding display region, the content to be displayed is displayed in the corresponding display region again. That is, in the case when a plurality of categories of contents need to be displayed simultaneously in the same display region but cannot be displayed simultaneously, at least a part of the later-acquired content is displayed in other available display regions until it can be displayed in the display region. For example, in the division solution of FIG. 2, the information related to the occupant’s journey and the information related to the function control are corresponding to the first region 206 in advance, and the information related to the audio-visual entertainment, the communication information and the life service information are corresponding to the second region 207 in advance. In a case, the content to be displayed is a map, and its corresponding display region is the first region 206. However, the function control panel has been displayed in the first region 206, and its remaining display area is too small to display the map. At this time, the map may be displayed in the second region 207 with a lower visual comfort than the first region 206. When the function control panel is no longer displayed in the first region 206, the map is displayed again in the first region 206. In these embodiments, the step of determining the target display region on the sidelite glass based on the content to be displayed further includes: determining a category of the content to be displayed; determining a corresponding display region based on the determined category; when other content has been displayed in the corresponding display region, determining whether the remaining display area of the corresponding display region is sufficient to display the content to be displayed; if the remaining display area is sufficient to display the content to be displayed, determining the corresponding display region as the target display region; otherwise, at least determining other available display regions in the at least two display regions as the target display region, and optionally, displaying a part of the content to be displayed in the corresponding display region. In addition, the display control method may further include: when the corresponding display region stops displaying other content, re-determining the corresponding display region as the target display region and displaying the content to be displayed therein. In this way, display conflict can be avoided, and the flexibility of sidelite glass display is further increased.
[0099] In some embodiments, the at least two display regions are pre-divided according to the visual comfort of the occupant by: performing statistics and analysis on gaze frequencies and / or gaze durations of a plurality of occupants at a plurality of positions on the sidelite glass when seated in the seat; and dividing the at least two display regions according to statistics and analysis results. The plurality of positions may be, for example, one or more of the central region 201, the first corner region 202, the second corner region 203, the third corner region 204, and the fourth corner region 205 in FIG. 2. It can be understood that two, three, four, six, seven, eight, and other numbers of positions may also be preset on the sidelite glass 200, and statistics and analysis are performed on the gaze frequencies and / or gaze durations of a plurality of occupants at these positions on the sidelite glass when seated in the seat to determine the visual comfort of these positions for the occupants. In this way, the visual comfort of different positions on the sidelite glass for the occupants can be predetermined, which facilitates the division of the display region.
[0100] In some embodiments, the size of the target display region may be adjusted. The adjustment may include expansion or contraction. In these embodiments, the display control method 100 further includes: adjusting the size of the target display region according to a display area required by the content to be displayed, or in response to the determined category belonging to one of one or more specific categories, or in response to a passively received control instruction. For example, when the display area required by the content to be displayed exceeds the area of the target display region, the target display region may be expanded; when the determined category is information related to audio-visual entertainment, the target display region may also be expanded; or, when a size adjustment instruction for the target display region from the occupant is received, the size of the target display region may be adjusted according to the instruction requirements. In this way, the display area can be adjusted according to actual display requirements, thereby improving the display flexibility.
[0101] In some embodiments, after the occupant is seated in the seat beside the sidelite glass, height data or eyeball height data of the occupant may be acquired, and the position of the target display region on the sidelite glass may be adjusted in the vertical direction based on the acquired height data or eyeball height data. In an example, a position of the target display region in the vertical direction (for example, a position of a geometric center thereof) corresponds to a height reference value or an eyeball height reference value (for example, 140 cm, 160 cm, or 165 cm) . A rule for adjusting the position of the target display region in the vertical direction according to the difference between the height data or the eyeball height data and the reference value is preset. For example, when the difference is positive (that is, the height data or the eyeball height data exceeds the height reference value or the eyeball height reference value) , the target display region is moved upward in the vertical direction by a distance equal to the difference; and when the difference is negative (that is, the height data or the eyeball height data is smaller than the height reference value or the eyeball height reference value) , the target display region is moved downward in the vertical direction by a distance equal to the absolute value of the difference. Therefore, after the height data or the eyeball height data of the occupant is acquired, a difference between the acquired height data or eyeball height data and the height reference value or eyeball height reference value corresponding to the current position of the target display region may be determined, and the position of the target display region on the sidelite glass may be adjusted in the vertical direction according to the difference and the position adjustment rule. In another example, a plurality of corresponding different height ranges or eyeball height ranges (e.g., 160-165 cm, 165 cm -170 cm) may be preset for a plurality of different preset positions of the target display region on the sidelite glass (e.g., a plurality of different preset positions of its geometric center) . After the height data or the eyeball height data of the occupant is acquired, the target display region is adjusted in the vertical direction to a position corresponding to a range where the acquired height data or eyeball height data is located. The height reference value or the eyeball height reference value or the height range or the eyeball height range of the occupant may be determined through scientific experiments. In one example, occupants of standard height or near-standard height are selected respectively by group to participate in the experiment and the display regions are divided. The groups may include, for example, a 6-8 year-old children group, a 9-10 year-old children group, an 11-12 year-old children group, a teenager group (male) , a teenager group (female) , an adult group (male) , an adult group (female) , etc. In addition to the five positions provided on the sidelite glass in the above experiment, a plurality of positions respectively corresponding to the five positions are additionally provided above and / or below the five positions in the vertical direction (for example, such that for each of the five positions, the total number of positions in the vertical direction is greater than the number of groups) . The visual comfort of these positions on the sidelite glass for this group of occupants is determined by group, and the display regions are divided. For each group, the average height value or the average eyeball height value of the occupants in the group may be used as the height reference value or the eyeball height reference value corresponding to the position of the divided display region in the vertical direction; or the height range or the eyeball height range of the occupants in the group may be used as the height range or the eyeball height range corresponding to the position of the divided display region in the vertical direction. In this way, the position of the target display region in the vertical direction may be adjusted according to the height or eyeball height of the occupant, thereby further improving the visual comfort of the occupant.
[0102] In some embodiments, the content to be displayed may be acquired in response to a start of the means of transportation, an actively determined control instruction, or a passively received control instruction. These control instructions may be received via a vehicle-machine interface, a communication module, and / or a human-computer interaction module. For example, when a vehicle is started, the host system receives a control instruction for starting the vehicle or sends the control instruction for starting the vehicle by itself, or when a sensor detects that the occupant is seated in the seat, the host system receives the control instruction of the occupant being seated, acquires information (such as greeting message, environmental information, etc. ) related to the occupant’s journey, and then displays the information in the target display region on the sidelite glass. The sensor may be, for example, a pressure sensor disposed in the seat or an infrared sensor or an image sensor disposed beside the sidelite glass for detecting whether the occupant is located in the seat. For another example, when the occupant performs a display start operation (for example, clicking an in-vehicle touchscreen, pressing a physical button, or selecting on a user device) , the host system receives a control instruction for starting display, acquires content to be displayed selected by the occupant, and then displays the content to be displayed on the sidelite glass. For another example, the host system first acquires information related to a vehicle and / or an occupant, and then determines content to be displayed based on the acquired information. The information related to the vehicle and / or the occupant may include location information, status information, environmental information of the vehicle, and / or personal information of the occupant. The location information of the vehicle may include a current geographic location of the vehicle, for example, a country, a province, a city, a district, a street, a house number, and longitude and latitude, etc. The status information of the vehicle may include information related to the vehicle’s own status, for example, a parking status, a driving status, and a fault status, etc. The environmental information of the vehicle may include weather forecast information of the destination, real-time weather information of a current location of the vehicle, real-time environmental parameters in the vehicle, and the like. The weather forecast information may include changes of such as air temperature, humidity, wind speed, air quality, and air pressure upon arrival at the destination or within a certain period of time in the future at the destination (for example, the duration of the occupant staying at the destination) . The real-time weather information may include real-time air temperature, humidity, wind speed, air quality, air pressure, etc. The real-time environmental parameters may include temperature, humidity, air quality, light, odor, sound, etc. sensed by sensors within the vehicle. The personal information of the occupant may include personal profiles (such as age, height, gender, etc. ) and preferences, etc. For example, when the location information of the vehicle indicates that the vehicle is about to arrive at the destination, information such as a dressing index, dining and accommodation information, and travel information related to the destination is acquired. When the status information of the vehicle indicates that the vehicle is in a parking state, information related to audio-visual entertainment is acquired. When the environmental information of the vehicle indicates that the in-vehicle temperature is low, information related to function control is acquired. When the occupant has a specific preference, corresponding content to be displayed is acquired, or content to be displayed that the occupant may be interested in may be estimated according to information such as age, height, and gender of the occupant. In this way, the content to be displayed may be acquired according to actual needs, which is suitable for different application scenarios and increases the diversity and flexibility of display.
[0103] In some embodiments, in the case that one or more display stop conditions are met, displaying the content in the target display region is stopped, that is, when one or more display stop conditions are met, displaying the content in the target display region is stopped. The display stop conditions may include: the occupant leaves the seat; the sidelite glass is lowered; a control instruction related to stopping display is actively determined or passively received; the occupant arrives at the destination; and / or the means of transportation stops working. Displaying the content in the target display region is stopped when it is detected that the occupant leaves the seat or the sidelite glass is lowered. For example, whether the occupant leaves the seat may be detected via a sensor. The sensor may be, for example, the aforementioned pressure sensor or infrared sensor for detecting that the occupant is seated in the seat. It is also possible to detect whether the sidelite glass is lowered via a sensor. The sensor may be, for example, a Hall sensor. In addition, displaying the content in the target display region may be stopped when the control instruction related to stopping display is actively determined or passively received. For example, when the playing of a movie or video ends, the host system receives a control instruction of ending the playing, and stops displaying in the target display region. For another example, the displayed content (such as a game) requires an occupant to interact, but if the host system determines that no interaction signal is received within a certain time period, it stops displaying in the target display region. For another example, when the occupant performs a display stop operation (for example, clicks a vehicle-mounted touchscreen, presses a physical button, or selects on a user device) , the host system receives a display stop control instruction, and it stops displaying in the target display region. In this way, the stopping of the display can be flexibly controlled, thereby extending the service life of the device and satisfying different needs of the occupant.
[0104] In some embodiments, the display of the sidelite glass may be realized by a projection display function layer and / or an autonomous display function layer. The projection display function layer may cooperate with the projector to image together, and the autonomous display function layer may be controlled by the display chip to image. The projection display function layer and / or the autonomous display function layer may be laminated into the sidelite glass or attached to the surface of the sidelite glass, which may cover the entire sidelite glass or may cover a partial region of the sidelite glass. For example, in the case where the size of the display region may be dynamically adjusted according to the display area required by the content to be displayed, or the position of the target display region may be dynamically adjusted according to the height or the eyeball height of the occupant, since the position and / or size of the display region is not fixed, the projection display function layer and / or the autonomous display function layer may cover the entire sidelite glass, or at least needs to cover most of the sidelite glass. As in FIG. 2, the projection display function layer and / or the autonomous display function layer covers at least a region obliquely in front of the occupant and a region beside the occupant. For another example, without dynamic adjustment, the projection display function layer and / or the autonomous display function layer may cover only the display region. As in FIG. 2, the projection display function layer and / or the autonomous display function layer covers at least the first region 206 and the second region 207. It can be understood that although the display regions on the sidelite glass are independent of each other in physical position, it does not mean that the formation manner thereof must be completely independent, for example, two display regions are separated by a gap, and in order to facilitate production and maintain relatively uniform light transmittance, the projection display function layer and / or the autonomous display function layer may cover the two display regions and the gap region therebetween.
[0105] In some embodiments, the respective content is projected on the target display region by at least one projector. The projector may be disposed in the interior of the vehicle, such as at the vehicle roof or center armrest. When there are multiple display regions on the sidelite glass, only one projector may be provided, and the contents to be displayed are projected onto the corresponding target display regions respectively by controlling the projection direction of the projector, thereby saving installation space and production cost. Alternatively, two or more projectors may be provided, and the contents to be displayed are projected onto the corresponding target display regions respectively in a one-to-many or one-to-one manner, to further ensure stability and accuracy of information display.

Here, the autonomous display function layer 42 is shown as an example. In other embodiments, the sidelite glass assembly 400 may include only the projection display function layer, or both the projection display function layer and the autonomous display function layer 42. The display control device 40 includes a processor (e.g., a central processing unit (CPU) ) 401 and a memory 402 coupled with the processor 401. The memory 402 is configured to store computer-executable instructions, and the processor 401 executes the computer-executable instructions to perform the display control method for sidelite glass of a means of transportation. Those skilled in the art may understand that the autonomous display function layer 42 may be, for example, a flexible OLED display or a LCD display, which may be laminated into the sidelite glass 41 or attached to the surface of the sidelite glass 41 to form as a whole with the sidelite glass 41. The sidelite glass assembly 400 can control the autonomous display function layer 42 to display through the display control device 40. In addition, a touch layer may also be provided on the sidelite glass 41 to realize interaction with the occupant. The touch layer may also be laminated into the sidelite glass 41 or attached to the surface of the sidelite glass 41 to form as a whole with the sidelite glass.

[0112] In the embodiment of FIG. 5, the display system 500 includes only one projector 51, and when contents need to be displayed in different display regions on the sidelite glass, the contents to be displayed may be projected onto the corresponding display regions respectively by controlling the projection direction of the projector 51. When contents need to be displayed in two or more display regions simultaneously, the display independence of each of these display regions can be ensured by designing the hardware structure of the projector and editing its software. In this way, installation space and production cost can be saved.
[0113] In some embodiments, the display system 500 may include at least two projectors respectively corresponding to at least two display regions, so that when displaying on a certain display region, the corresponding projector is controlled to project the content to be displayed onto the display region. In this way, the stability and accuracy of information display can be further ensured.
[0114] In some embodiments, the display system 500 may not include the projector 51, and instead, the sidelite glass is provided with an autonomous display function layer for active display, so as to display the acquired content. The autonomous display function layer may be, for example, a flexible OLED display or a LCD display, which may be laminated into the sidelite glass or attached to the surface of the sidelite glass to form as a whole with the sidelite glass. In addition, a touch layer may also be disposed on the sidelite glass to achieve interaction with the occupant. The touch layer may also be laminated into the sidelite glass or attached to the sidelite glass surface to form as a whole with the sidelite glass.
[0115] In some embodiments, the projection display function layer 52 or the autonomous display function layer 42 at least covers the target display region on the sidelite glass. That is, in order to achieve the display function of the target display region, the projection display function layer and / or the autonomous display function layer need / needs to cover the target display region.
[0116] In some embodiments, the projection display function layer 52 or the autonomous display function layer 42 covers only a partial region on the sidelite glass.

In this way, the production of the sidelite glass can be facilitated and higher display flexibility is possible.
[0118] In some embodiments, the projection display function layer 52 or the autonomous display function layer 42 covers a pre-divided display region on the sidelite glass. In this way, the production cost can be saved and the light transmittance of the sidelite glass can be improved to some extent.

The plurality of components may further include a storage module, for example, a magnetic disk or an optical disk, etc.
[0122] Moreover, the methods described above can alternatively be implemented by a computer-readable storage medium. The computer readable storage medium carries computer readable program instructions for performing various embodiments of the present invention. The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. More specific examples (non-exhaustive) of the computer readable storage medium would include the following: a portable computer diskette, a hard disk, a random access memory (RAM) , a read-only memory (ROM) , an erasable programmable read-only memory (EPROM or Flash memory) , a static random access memory (SRAM) , a portable compact disc read-only memory (CD-ROM) , a digital versatile disk (DVD) , a memory stick, a floppy disk, a mechanically encoded device, punch-cards or raised structures in a groove such as those having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable) , or electrical signals transmitted through a wire.
[0123] Therefore, in another embodiment, the present disclosure provides a computer-readable storage medium having computer-executable instructions stored thereon for performing the display control method in the various embodiments described with respect to FIG. 1 in the present disclosure.
[0124] The present disclosure further provides a computer program product, which is tangibly stored on a computer-readable storage medium and includes computer-executable instructions that, when executed, cause at least one processor to perform the display control method in the various embodiments described with respect to FIG. 1 in the present disclosure.
[0125] Generally, various example embodiments of the disclosure may be implemented in hardware or special purpose circuits, software, firmware, logic or any combination thereof. Some aspects may be implemented in hardware, while other aspects may be implemented in firmware or software which may be executed by a controller, microprocessor or other computing device. While various aspects of embodiments of the disclosure are illustrated and described as block diagrams, flowcharts, or represented by using some other graphs, it will be appreciated that the blocks, apparatus, systems, techniques or methods described herein may be implemented in, as non-limiting examples, hardware, software, firmware, special purpose circuits or logic, general purpose hardware or controller or other computing devices, or some combination thereof.
[0126] Although various exemplary embodiments of the present disclosure described above may be implemented in hardware or dedicated circuits, the display control apparatus described above may be implemented in the form of hardware or software, because: in the 1990s, it can be easily determined whether a technical improvement belongs to a hardware improvement (for example, an improvement to a circuit structure such as a diode, a transistor, or a switch) or a software improvement (for example, an improvement to a method procedure) . However, with the continuous development of technology, the improvements of many current method flows can almost be implemented by programming the improved method flows into a hardware circuit, in other words, by programming different programs for the hardware circuit to obtain a corresponding hardware circuit structure, that is, the hardware circuit structure is changed, so the improvements of such method flows can also be regarded as direct improvements of the hardware circuit structure. Therefore, an improvement of a method procedure cannot be implemented by using a hardware entity module. For example, a programmable logic device (PLD) (for example, a field programmable gate array (FPGA) ) is such an integrated circuit, and a logical function of the programmable logic device is determined by a user through device programming. A designer performs self-programming to “integrate” a digital system on a programmable logic device, without requiring a chip manufacturer to design and manufacture a dedicated integrated circuit chip. Moreover, today, instead of manually manufacturing an integrated circuit chip, the programming is mostly implemented by “logic compiler” software, which is similar to the software compiler used during program development and writing, and the original code to be compiled is also written in a specific programming language, which is called hardware description language (HDL) , but HDL is not only a kind, but many kinds, such as Advanced Boolean Expression Language (ABEL) , Altera Hardware Description Language (AHDL) , Confluence, Cornell University Programming Language (CUPL) , HDCal, Java Hardware Description Language (JHDL) , Lava, Lola, MyHDL, PALASM, Ruby Hardware Description Language (RHDL) , etc., and most commonly used are Very-High-Speed Integrated Circuit Hardware Description Language (VHDL) and Verilog. It should also be clear to those skilled in the art that the hardware circuit for implementing the logic method flow can be easily obtained by only programming the method flow in the above several hardware description languages as logic programming and programming into the integrated circuit.
[0127] The computer-readable program instructions or the computer program product for executing various embodiments of the present disclosure can also be stored in the cloud, and when it needs to be called, the user can access the computer-readable program instructions stored in the cloud for executing one embodiment of the present disclosure through the mobile Internet, the fixed network or other networks, thereby implementing the technical solutions disclosed according to various embodiments of the present disclosure.
[0128] Although the embodiments of the present disclosure have been described with reference to several specific embodiments, it should be understood that the embodiments of the present disclosure are not limited to the specific embodiments disclosed. The embodiments of the present disclosure are intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. The scope of the claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
