Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of exhibition hall control, in particular to a digital multimedia exhibition hall interactive display control system. BACKGROUND

[0002] In most exhibition halls, the opening, closing and content control of each display device are independent. For example, during the opening of the exhibition hall, the management personnel need to run to different positions to manually open each device (such as display, light, sound, etc.) one by one. Such an operation process is inefficient and prone to errors, and it is difficult to comprehensively process the interactive devices and the corresponding associated device groups in the exhibition hall, resulting in that the exhibition hall cannot achieve a unified display effect, and the interactive effect is reduced.

[0003] For example, Chinese Patent Publication No. CN114675577A discloses an intelligent exhibition hall central control service system based on artificial intelligence, which includes a display target statistical module, a display area device setting module, a display area device control module, a display area projection control module, an exhibition personnel exhibition distribution state recognition module, a projection screen adaptive display parameter analysis module, a display content database, a control database, an external environment light source parameter acquisition module, a projection screen adaptive photoelectric parameter analysis module, and a projection screen display intelligent control terminal. By intelligently and flexibly controlling the opening and closing, display parameters, projection background and photoelectric parameters of the projection screen in the corresponding display area of the cultural relic exhibition hall, the projection screen is comprehensively and multidimensionally controlled.

[0004] For example, Chinese Patent Publication No. CN119165782A discloses a centralized control method and system based on intelligent conference rooms and smart exhibition halls. The method includes: respectively collecting people flow data of the intelligent conference rooms and the smart exhibition halls, and dividing the intelligent conference rooms and the smart exhibition halls into regional grids; determining the personnel density of each grid area of the intelligent conference rooms and the smart exhibition halls according to the people flow data, and centrally controlling the environmental state of each grid area according to the personnel density; respectively collecting the environmental data in the adjusted intelligent conference rooms and smart exhibition halls, and calculating the overall environmental suitability of the intelligent conference rooms and the smart exhibition halls based on the environmental data; according to the overall environmental suitability, continue to control the environmental state of each grid area, and centrally control the energy consumption state of the intelligent conference rooms and the smart exhibition halls.

[0005] In the prior art, the control of the exhibition hall is realized by adjusting the orientation and position of the image in the exhibition hall, and the control of the exhibition hall environment suitability is realized by standard processing of environmental factors. However, the prior art emphasizes the working condition of a single interactive device, ignores the multiple associated device groups triggered by the interactive device, and the state of the multiple associated device groups cannot be updated in time, resulting in a decrease in the efficiency of the coordinated control of the exhibition hall. SUMMARY

[0006] In order to solve the above technical problems, the technical scheme adopted by the present application is: a digital multimedia exhibition hall interactive display control system, comprising: a device acquisition module, configured to acquire the coordinates, device types and associated device group quantities of interactive devices in the exhibition hall, and record the working states of each interactive device.

[0007] A state definition module is configured to define state coordination rules of associated device groups in each exhibition hall according to the working states of interactive devices in each exhibition hall and in combination with the working logic of the interactive devices.

[0008] An instruction switching module is configured to determine a coordinated operation list of multi-device coordinated work in each exhibition hall according to the state coordination rules of interactive devices in the exhibition hall, in combination with the update sequence and update time of the working states of associated device groups after the interactive devices trigger operation instructions.

[0009] A path analysis module is configured to analyze the coordinated operation list, map the coordinated operation list to a plurality of interactive devices, determine a visit path corresponding to the coordinated operation list according to the state category of the associated device group after each mapping.

[0010] An instruction updating module is configured to compare the working states of interactive devices across devices according to the visit path corresponding to the coordinated operation list, determine operation instructions for updating each interactive device at different associated device groups, and display each interactive device according to the update content of the operation instructions.

[0011] The present application has the following advantages: first, the present application uniformly manages interactive devices and associated device groups, determines state coordination rules of the two types of devices when working, and forms a coordinated operation list of multi-device coordinated work through the update sequence and update time of the working states, so that a visit path is generated based on the coordinated operation list, which can ensure the coherence and individualization of the display process and reduce the need for manual intervention when using each device in the exhibition hall.

[0012] Second, the present application solves the problems of ambiguous coordination relationship between devices and lack of predictability of state changes by constructing an event connection graph, analyzing state trajectories and change trends through coordinated work proportion, quantifies the relevance between each device, and further determines the target state using historical trajectories to prevent current device state adjustment lag and adapt to dynamic scenarios.

[0013] Third, the present application selects a target scenery way by simulating the scenery, generates a coordinated operation list based on resource allocation, calculates the probability using a step-by-step self-check, divides the state category, quantifies the feasibility of current device state conversion, and facilitates subsequent intervention on device setting parameters; finally, the interest score generates a visit path, and the node intersection is analyzed to dynamically adjust the path, which realizes the visit guidance and dynamic interconnection optimization of the exhibition hall.

[0020] Embodiments of the application will be described in detail below. The embodiments described below are exemplary and are only used to explain the application and cannot be understood as a limitation of the application. If the specific technology or conditions are not specified in the embodiments, the technology or conditions described in the literature in the art or according to the product instructions are used.

[0021] Reference Figure 1 A digital multimedia exhibition hall interactive display control system, comprising: a device acquisition module, a state definition module, an instruction switching module, a path analysis module and an instruction updating module; wherein the output end of the device acquisition module is connected with the state definition module, the output end of the state definition module is connected with the instruction switching module, the output end of the instruction switching module is connected with the path analysis module, and the output end of the path analysis module is connected with the instruction updating module.

[0022] The device acquisition module is used to acquire the coordinates, device types and associated device group quantities of the interactive devices in the exhibition hall, and record the working states of each interactive device.

[0023] The state definition module is used to define the state coordination rules of the associated device groups in each exhibition hall according to the working states of each interactive device in the exhibition hall and in combination with the working logic of the interactive devices.

[0024] The instruction switching module is used to determine the coordinated operation list of the multi-device coordinated work in each exhibition hall according to the state coordination rules of the interactive devices in each exhibition hall and in combination with the update sequence and update time of the working states of the associated device groups after the interactive devices trigger the operation instructions.

[0025] The path analysis module is configured to analyze the collaborative operation list, map the collaborative operation list to the plurality of interactive devices, associate the state category of the device group after each mapping, and determine the visiting path corresponding to the collaborative operation list.

[0026] The instruction updating module is configured to compare the working states of the interactive devices across devices according to the visiting path corresponding to the collaborative operation list, determine the operation instruction updated by each interactive device at different associated device groups, and display the interactive devices according to the updated content of the operation instruction.

[0027] The working state is used to indicate the actual running condition of the interactive device. For example, the working state of the game machine can include the current number of players, the game progress, the number of people in the sensor reporting area, and other descriptions indicating that the current device is running.

[0028] In the current scheme, the system core is no longer a single switch instruction, but a unified environment state, such as a film playing, a game being played, and an audience being watched, which directly indicates the state of interaction. At this time, the operation of any terminal, such as a tablet central control and a sensor, will intend to change this global state. After the system receives the intention, it will calculate a series of devices, such as a projector, a light, and a game machine, which need to execute the action list, and coordinate them to orderly switch to the new state.

[0029] As shown in Figure 2 , when recording the working state of each interactive device, the device acquisition module further includes: taking the associated device group of the current interactive device as a verification subject, identifying the working state and display requirement of each associated device group under the coordination after the current interactive device triggers the operation instruction.

[0030] If the display requirement is met, the working state of the associated device group is switched, and the working state of the current interactive device is mapped to the plurality of associated device groups.

[0031] If the display requirement is not met, the performance index state of each associated device group is extended, including the life of the projector bulb, the refresh rate of the LED screen, the CPU / memory occupation of the server, the network delay jitter, and other states, to determine the running condition of the current associated device group; the environment state of the current associated device group is introduced, the working state of the associated device group is associated with the environment state, the occurrence frequency of the performance index state of the current associated device group is obtained, and the occurrence frequency is filled into the working state of each interactive device.

[0032] These performance indicators, after being combined with environmental conditions, will highlight the parameters received by the sensor, such as sensor device group performance indicators: human flow sensor response time ≤ 1s, temperature and humidity sensor accuracy ± 0.5℃ / ± 5%RH; environmental condition range: temperature 18-25℃, relative humidity 40%-60%, projected area illumination ≤ 100lx.

[0033] In obtaining the working state of the associated device group and the interactive device, the interactive device is generally a touch screen, a button, a joystick, etc., which is used to receive the operation instruction of the user and trigger the display of the related image; the associated device group corresponds to a projector, a sound, a light, an LED screen, a smoke sprayer and a water sprayer, etc., which are used to complete the playing and execution of the content; the interactive device records the availability of each associated device group through the stored data to comprehensively express the working state of the interactive device; the display requirement indicates the content that can be played and displayed on the interactive device; when the display requirement is met, the associated device group of the current interactive device executes the related content through the central control system, and the devices involved in the execution are stored in the form of working state; if the display requirement is not met, the fault condition of the device needs to be recorded and the data is counted to the interactive device working state.

[0034] At this time, the display requirement refers to the comprehensive standard of environmental conditions, device parameters and system performance that must be met to achieve a specific interactive display effect; and the working state refers to the current running parameters and state of each associated device group, which ensures that the content required by the current interactive device can be interactively executed.

[0035] At this time, the obtained interactive device display emphasizes two-end interaction, or in the form of environmental state interaction, each terminal interaction is converted into a state connection form, after obtaining the number and the number of terminals in the exhibition hall, the number of machines controlled by each terminal is received, when any one operation instruction is met, the working state of each machine is interacted with the machine involved in each operation instruction, forming a two-end cooperative form.

[0036] For example, when implementing projection playing, multiple light devices need to be controlled to make the surrounding light dim, and then use part of the light and other sensors for dynamic display, and there are also some devices using multiple operation states, such as interactive devices in the form of game machines, which have multiple users operating together, at this time, the interactive state reported by multiple devices needs to be obtained, and the working state of each machine is interacted to form a two-end cooperative closed loop of terminal operation-environment response.

[0037] In an embodiment of the present application, in the state definition module, it is necessary to determine the running parameters of each interactive device and the running parameters of the corresponding associated device group, and to define the rules of how each interactive device triggers device coordination with the operation instruction triggered by the interactive device as the trigger boundary of state coordination.

[0038] As Figure 3 shown, the implementation of the state definition module includes: in response to the working state of the interactive device, taking the interactive device as the starting point, taking the associated device group as the node, and taking the mapping relationship between the interactive device and the associated device group as the edge, obtaining the event connection graph of each associated device group and the interactive device; the nodes in the event connection graph represent the associated device group and the interactive device, and the edges represent the logical relationship between the associated device group and the interactive device after the interactive device triggers the operation instruction, and the mapping relationship between the associated device group and the interactive device is explained according to the current scene of the interactive device, such as multiple associated device groups connected with the light device group, the projection device group and the sensor device group, forming a form such as interactive device- associated device group 1- associated device group 2, forming a relatively complete action sequence with the working state of each device in the current scene, to complete the step-by-step sequential execution process of the associated device group.

[0039] For each node of the event connection graph, identify the collaborative working proportion of each node, and the collaborative working proportion indicates the weight distribution form under the execution of a certain operation instruction, such as after the user clicks to play the film, the system allocates the main light: 55% (mainly bearing brightness adjustment), the atmosphere light: 30%, and the auxiliary environment light and the dynamic light: 15% (responding to user interaction), at this time the proportion value corresponding to multiple lights is regarded as the current collaborative working proportion. Based on the collaborative working proportion, the working state trajectory of the associated device group after the interactive device triggers each operation instruction is identified, and the state change trend of each node is set through the working state trajectory.

[0040] It should be noted that the collaborative working proportion represents the weight distribution proportion, at this time each associated device group has a normal brightness value when working normally, and this weight is used as the part of the associated device group in dynamic adjustment, for example, the basic brightness of the main light is 20%, at this time the specific brightness of the corresponding device is adjusted in the form of multiplying the configured collaborative working proportion by the adjustment amount and adding the basic value.

[0041] Further, the collaborative working proportion will be set based on the device contribution weight and the availability rate of each device, and the collaborative working proportion = (device contribution weight x availability rate) / Σ (all device contribution weights x availability rates); in the film playing scene, the projection contribution weight is 0.4, the main light is 0.3, and the sound is 0.3; the availability rate = normal working time / total running time x 100%.

[0042] Specific to the corresponding associated device group of the light device group, the projection device group and the sensor device group, the light device group mainly deals with brightness, color and dynamic effect of light; the projection device group is to determine the brightness, contrast of the current playing content, and the coordinates after projection, and configure the weight of the corresponding associated device group according to these data, which indicates the necessity of adjusting the corresponding value during interaction; the sensor device group emphasizes the data collected in each area of the exhibition hall, sets the weight according to the ratio of the amount of data collected in the area to the total amount of data, and uses this weight to indicate the current device working state.

[0043] The working state trajectory mentioned above represents the trajectory of the working state change of the current associated device group when working, for example, if the current associated device group is the main light, then the change of the brightness and color of the main light is detected at this time, and the change of the brightness and color with the time point is regarded as the working state trajectory; the state change trend is to segment the values of brightness, color, light, resolution, brightness, contrast, and coordinates after projection in the associated device group, and determine whether the current associated device group is working normally according to the change trend of these values with the time point.

[0044] Based on the state change trend of each node, the relevance of the state change of each node is identified, and the state coordination rule corresponding to the current associated device group is configured according to the relevance of the state change of each node.

[0045] When configuring the state coordination rule corresponding to the current associated device group, the relevance of the current associated device group when the state changes is taken as the basis for setting according to the specific distribution form of the data collected by the light device group, the projection device group and the sensor device group, the corresponding adaptive state coordination rule is found in the database, and the implementation mode of the state coordination rule further includes: the state change trend of each node is calculated according to the type of the associated device group, the change rate of the state change trend and the historical state change trend, the Pearson correlation coefficient is used to calculate the correlation value between each associated device group, such as the correlation value of the light device group, the projection device group and the sensor device group, the correlation calculation result is obtained, and the state coordination rule is configured according to the correlation calculation result. As for the Pearson correlation coefficient used to quantify the correlation value, the change rate of the state change trend is 0 minute average change rate, and the same scene data in the past 7 days is selected to judge the state of the current change trend relative to the historical data.

[0046] At this time, the correlation of the state change of each node is identified, the corresponding values in the state change trend are standardized, the values are normalized, the Pearson correlation coefficient is used to calculate the correlation value, and then the state cooperation rule is configured according to the correlation; the state cooperation rule is a set of various device state combinations, for example, when the operation instruction triggered by the interactive device is related to the light, the light will automatically retrieve the state cooperation rule from the database according to the calculated correlation value; as shown in the following content: the main light cooperation working proportion increases by 5% (correlation coefficient 0.92), the atmosphere light cooperation working proportion increases by 3% (correlation coefficient 0.85), and the dynamic light cooperation working proportion decreases by 2% (correlation coefficient 0.78), at this time, the light corresponding to the current associated device group is adjusted one by one, and the projection device adjusts the brightness, contrast, and coordinates of the projection to determine the position of the current playing content. The state cooperation rule retrieved by the sensor is to change the sampling density of each area data to obtain a more accurate personnel tracking process.

[0047] Preferably, when identifying the cooperation working proportion of each node, the implementation further includes: based on the working state of the current interactive device, if the operation instruction is obtained, the working state of the associated device group is controlled according to the working state of the interactive device, and the cooperation working proportion of the associated device group after the working state conversion is obtained. The cooperation working proportion at this time will directly obtain from the database by distributing the weights of the corresponding operation instruction to the light device group, the projection device group and the sensor device group.

[0048] When the cooperation working proportion after the working state conversion is greater than the target state, the weight update is triggered, the cooperation working proportion is reacquired, and the cooperation working proportion of the corresponding node is set to the working state trajectory at the update time. Greater than the target state, which represents that the current associated device group working and the historical data exist deviation, needs to determine whether the weight distribution proportion set at this time exceeds the cooperation working proportion set in the historical data, and if it exceeds, it may represent that the corresponding associated device group exists high load, high load risk situation, and needs to improve the monitoring of the related devices. If it is less than, it means that the current weight distribution is close to the historical data, and at this time, it is not necessary to directly adjust and improve, and only the corresponding configured value is recorded.

[0049] It should be noted that when the weight update is triggered, the cooperation working proportion is recalculated, so that the new proportion is deviated from the target state by ≤5%; if it is still greater than the target state, only the deviation is recorded, and the update is not repeated, so as to prevent the data from being updated continuously and cause a loop hazard.

[0050] If it is less than or equal to the target state, the weight update is not triggered, and the time when the operation instruction is acquired is set to the working state trajectory.

[0051] The collaborative working proportion of the operation instruction is defined in the database in advance according to different instructions, and the associated device group mainly controlled by each operation is described, such as the light device group mainly controlling the form of the main light, to describe the state advancing process of each associated device group.

[0052] Preferably, the implementation mode of the target state comprises: analyzing the current working state trajectory and the historical working state trajectory in time sequence, after time alignment, analyzing the correlation of the current working state trajectory and the historical working state trajectory, and regarding the collaborative working proportion corresponding to the working state trajectory as the current target state when the correlation value is maximum.

[0053] When the target state difference is set, the working state of the current associated device group, such as the light, is first identified in the form of time point advancing, and then the current working state trajectory and the historical working state trajectory are aligned; if the current working state trajectory represents the main light brightness change sequence with time, the historical working state trajectory represents the main light brightness change sequence in the same scene in the past, at this time, the collaborative working proportion that can appear under the light change is determined, and the calculation method of the Pearson correlation coefficient is used to calculate the relativity of the two working state trajectories, if there is a set collaborative working proportion under the current light change and the historical light change under the maximum correlation coefficient, it is explained that the collaborative working proportion value is optimal relative to the historical state under the current processing, and this value can be used to judge whether the current collaborative working proportion is set too large after being obtained, to prevent the load of part of the associated device group from increasing.

[0054] It should be noted that the working states of the multiple associated device groups involved in the current processing process will be mapped to the interactive device at the same time, to explain how the other devices work when the user touches the display screen or other interactive terminal, so as to facilitate the control of the use of various devices in the exhibition hall.

[0055] In an embodiment of the present application, in the instruction switching module, the collaborative working proportion described under the collaborative working rules of the multiple groups of states set in the state definition module is summarized into a total collaborative operation list, and when the list is set, multiple fields corresponding to the processing process of the state definition module are created in the list, such as the exhibition hall unique identifier, the interactive device unique identifier, the operation instruction type, the associated device group current working state description, the state update time point, the current collaborative working proportion, the target state difference, whether the weight update is triggered, the new collaborative working proportion (if the update is triggered), the state and the record creation time, and multiple description field forms, to determine the process of the current interactive device and the associated device group control management.

[0056] For example, Figure 4As shown, the implementation mode of the instruction switching module includes: receiving state coordination rules of each associated device group in the exhibition hall, simulating the layout of each associated device group in the exhibition hall according to the update time and update order corresponding to the associated device group, and determining the associated device group responding to the operation instruction execution.

[0057] With the associated device group responding to the execution, the mapping relationship between each associated device group and the interactive device is recorded, and based on the available resource configuration of the associated device group, the corresponding target layout mode is determined from the candidate layout mode.

[0058] According to the target layout mode, the working state of the associated device group after execution is composed into a coordinated operation list.

[0059] It should be noted that the simulated layout describes the scene after receiving the current state coordination rules of the associated device, at which time the resources that can be configured by each associated device group in the corresponding scene are determined; the available resource configuration represents the parameters that can be arranged by the current associated device group in the corresponding scene, and the target layout mode represents the parameter set of multiple associated device groups in the corresponding scene. By inputting these parameter sets into the coordinated operation list, the specific parameters of the current associated device group can be obtained.

[0060] The above-mentioned candidate layout mode is a preset scheme of the exhibition hall in the corresponding scene, and the target layout mode is further determined by the overall scheme of the current associated device group when working one by one. At this time, the target layout mode is directly selected from the candidate layout mode by using the specific parameters of the associated device group.

[0061] When composing the coordinated operation list, the implementation mode further includes: for the associated device group in the coordinated operation list, using a step-by-step self-checking method to check the current associated device group, and determining the probability of the working state of the associated device group reaching the initial state from one state or multiple states; if the associated device group reaches the initial state, it means that the interactive device at the corresponding position has not performed the related operation, or the interactive device has not sent the operation instruction to the central control system, or the corresponding associated device group is in standby state and does not participate in the current coordinated interaction process; all of these represent the specific working conditions of the associated device group in the exhibition hall.

[0062] At this time, the step-by-step self-checking can check multiple devices according to the following contents, such as ① power supply: voltage fluctuation ≤ ± 5%; ② connection: network delay ≤ 50 ms, packet loss rate ≤ 1%; ③ basic function: projection picture integrity ≥ 95%, sound decibel 60-80 dB; ④ performance: CPU occupancy rate ≤ 70% and other self-checking methods, that is, whether the associated device group is working normally is gradually judged to complete the subsequent visit path setting under the cooperation of multiple devices.

[0063] The reaching probability is calculated by calculating the conditional probability of the associated device group from a state to the initial state, that is, given any one or more states, the probability of the associated device group transitioning to the initial state under the condition that the states are given.

[0064] The above step-by-step self-checking will gradually check the associated device group in terms of power supply, connection, basic functions, etc., to determine whether the associated device group is available.

[0065] The reaching probability corresponding to the associated device group is taken as input, and the state categories of each associated device are divided, and each associated device is described by state category. At this time, the state categories will be divided into active state, potential active state and initial state. The initial state will represent the reference standby state of the device group, the potential active state will represent the use of part of the function, the pre-allocation state or the use of low power consumption, and the active state will belong to the state of actively participating in collaborative work, full function operation and real-time response to user operation.

[0066] When dividing the three state categories, 0.9 and 0.5 are taken as thresholds, [0.9, 1] is taken as the state type of the initial state, and in the case of a value greater than 0.9, it indicates that the corresponding associated device group has a low frequency of use in the user interaction process and is in the initial configuration state for a long time, and does not need to be directly monitored. [0.5, 0.9) is regarded as a potential active state, which means that the corresponding associated device group has some functions participating in user interaction, which is a transition stage of user active interaction, and needs to be slightly increased. Monitoring; As for (0, 0.5), it represents that the corresponding device is used frequently, there are more user uses, and needs to be monitored in time. At this time, it is necessary to determine whether the device needs to be monitored in time according to the state category of the associated device group to complete the control of the overall exhibition environment.

[0067] In an embodiment of the present application, the path analysis module needs to refer to the state categories of the associated device group, synchronize these state categories to the path of the visit, determine the interest of the current user between different interactive projects and display images, bind the devices with interest under collaborative work, and regard the path of the corresponding device after binding as the current bound visit path.

[0068] As shown in Figure 5 The implementation of the path analysis module includes: mapping the collaborative operation list to the interactive device to form a path node, and regarding each interactive device corresponding to the associated device group as an auxiliary node. At this time, the path node is standardized by the spatial position and state category of the associated device group and the interactive device, a path containing spatial coordinates is formed, and the visit path is output by screening the path node.

[0069] The basic interest score is set for each path node according to the device type of the interaction device, and the interest multiplier is set based on the state category of the corresponding auxiliary node of each path node. The interest multiplier and the basic interest score are combined to obtain the interest score of each path node. At this time, the interest multiplier will set a score based on the state category of any one of the active state, the potential active state and the initial state, and the scores are set to 1.5, 1.2 and 0.8 in turn. As for the basic interest score, it will be set according to the device type of the interaction device, such as an interaction display screen 0.8, an immersive environment 0.9, etc. At this time, the basic interest score and the weighted average value of the multiple associated device groups are calculated, and the calculated value is normalized to prevent the interest score from being too large.

[0070] Further, the value of the basic interest score will be set according to the interaction frequency of the device and the display priority of the device. The display priority is a score value set in advance according to the arranged interaction device, and the interaction frequency is counted according to the number of uses of the corresponding device in an hour or other time period. That is, the basic interest score = interaction frequency weight (60%) + display priority weight (40%); interaction frequency ≥ 10 times / hour set to 0.9, interaction frequency 5-10 times / hour set to 0.8, interaction frequency < 5 times / hour set to 0.7; core exhibit associated device additional 0.1; at this time, the weights set by the interaction frequency and the display priority are selected as 60% and 40% respectively to obtain the basic interest score in the current scene.

[0071] Based on the interest score of each path node, the shortest path connection method is used to obtain the connection path between the path nodes. At this time, the distance between the path nodes is calculated using the Euclidean distance, and the value is normalized. Then the shortest path algorithm Dijkstra is used. The shortest path represents the minimum weighted sum of the Euclidean distance and the weight under the condition that the path node in the current exhibition hall is passable. At this time, it is required to connect the path nodes in the current exhibition hall as much as possible. The shortest path represents the path preferred by the user when moving. Since the highest interest path is needed to be obtained, the weight is set to 1 minus the interest score when the interest score is regarded as the weight. In this way, the shortest path can be used to obtain the relative interest concentrated visit path.

[0072] According to the number of path nodes intersected by the visit paths in different scenes, the output visit path is adjusted.

[0073] If the intersection is only one path node, the path node cannot form a relatively continuous visiting path. In this case, the intersection represents the highest interest node connected to the path node in each scene. The node is output alone, and the current path node and its auxiliary node are connected to form an output visiting path. If the intersection has two path nodes, the positions of the two path nodes in the exhibition hall are found. If the two path nodes can be directly connected in the exhibition hall, the two path nodes and their auxiliary nodes are combined to form an output visiting path, which represents a local path with high interest in multiple scenes. If the two path nodes cannot be directly connected, an intermediate node is added between the two path nodes. The spatial position of the intermediate node is within the minimum enclosing circle of the two path nodes. The intermediate node is selected from the path nodes with the highest interest score at the corresponding positions in multiple scenes. The intermediate node and the two path nodes are connected, and the connected path is regarded as an output visiting path. If the intermediate node cannot be connected, the two path nodes are returned, and a new intermediate node is obtained. The new intermediate node is traversed according to the interest score, until the two path nodes are connected through the intermediate node. The connected path nodes are regarded as an output visiting path. In this case, the relatively local visiting path indicates that the interactive device in the current exhibition hall is mainly concerned.
