Abstract
Description
Technical Field
[0001] This invention relates to the field of exhibition hall control technology, specifically a digital multimedia exhibition hall interactive display control system. Background Technology
[0002] In most exhibition halls, the activation, deactivation, and content control of each exhibit are independent. For example, during the opening of the exhibition hall, management personnel need to run to different locations to manually turn on each device (e.g., monitors, lights, sound systems). This operational process is inefficient and prone to errors, making it difficult to comprehensively manage interactive devices and related equipment groups within the exhibition hall. This results in a lack of unified display effects and a reduction in the interactive experience.
[0003] For example, Chinese Patent Publication No. CN114675577A discloses a smart exhibition hall central control service system based on artificial intelligence, including a display target statistics module, a display area equipment setting module, a display area equipment control module, a display area projection control module, a visitor distribution status recognition module, a projection screen adaptation display parameter analysis module, a display content database, a control database, an external environment light source parameter acquisition module, a projection screen adaptation 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 screens in the corresponding display areas of the cultural relics exhibition hall, the system achieves comprehensive and multi-dimensional control of the projection screens.
[0004] For example, Chinese Patent Publication No. CN119165782A discloses a centralized control method and system for smart conference rooms and smart exhibition halls. The method includes: collecting pedestrian flow data in smart conference rooms and smart exhibition halls respectively, and dividing smart conference rooms and smart exhibition halls into regional grids; determining the personnel density of each grid area in smart conference rooms and smart exhibition halls based on pedestrian flow data, and centrally regulating the environmental status of each grid area based on personnel density; collecting environmental data in smart conference rooms and smart exhibition halls after regulation respectively, and calculating the overall environmental suitability of smart conference rooms and smart exhibition halls based on environmental data; continuing to regulate the environmental status of each grid area based on the overall environmental suitability, and centrally regulating the energy consumption status of smart conference rooms and smart exhibition halls.
[0005] Existing technologies control the exhibition hall by adjusting the orientation and position of images within the hall, and by using standardized processing of environmental factors to achieve suitable environmental control. However, these technologies emphasize the operation of a single interactive device, neglecting the multiple associated device groups that trigger operation commands. This results in the inability to update the states of multiple associated device groups in a timely manner, leading to reduced efficiency in collaborative control of the exhibition hall. Summary of the Invention
[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a digital multimedia exhibition hall interactive display control system, including: a device acquisition module, used to acquire the coordinates, device type and number of associated device groups of interactive devices in the exhibition hall, and record the working status of each interactive device.
[0007] The state definition module is used to define the state coordination rules of related device groups in each exhibition hall based on the working state of the interactive devices in each exhibition hall and in combination with the working logic of the interactive devices.
[0008] The instruction switching module is used to determine the collaborative operation list for multiple devices working together in each exhibition hall based on the status coordination rules of interactive devices in each exhibition hall, combined with the update order and update time of the working status of associated device groups after the interactive devices trigger operation instructions.
[0009] The path analysis module is used to analyze the collaborative operation list, map the collaborative operation list to multiple interactive devices, and determine the visit path corresponding to the collaborative operation list by associating the status category of the device group after each mapping.
[0010] The instruction update module is used to compare the working status of interactive devices across devices according to the visit path corresponding to the collaborative operation list, determine the operation instructions updated for each interactive device in different associated device groups, and display each interactive device according to the updated content of the operation instructions.
[0011] The beneficial effects of this invention are as follows: First, by unifying the management of interactive devices and associated device groups, this invention determines the state coordination rules of the two types of devices during operation, and forms a collaborative operation list for multi-device collaborative work through the update order and update time of the working state. Based on the collaborative operation list, a visitor path is generated, which can ensure the continuity and personalization of the exhibition process and reduce the need for manual intervention when using various devices in the exhibition hall.
[0012] Second, this invention solves the problems of ambiguous collaborative relationships between devices and lack of predictability of state changes by constructing an event connection diagram and analyzing state trajectories and change trends through collaborative work ratio analysis. It quantifies the correlation between devices and further uses historical trajectories to determine the target state, preventing the current device state adjustment from lagging behind and failing to adapt to dynamic scenarios.
[0013] Third, this invention selects the target scene setting method through simulated scene setting, generates a collaborative operation list based on resource configuration, and uses a step-by-step self-check to calculate the probability of achievement, classify state categories, and quantify the feasibility of the current equipment state transition, which facilitates subsequent intervention in equipment setting parameters; finally, interest scores generate visitor paths, and the path is dynamically adjusted through node intersection analysis to realize visitor guidance and dynamic connectivity optimization of the exhibition hall.

[0020] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.
[0021] See Figure 1 A digital multimedia exhibition hall interactive display control system includes: a device acquisition module, a status definition module, an instruction switching module, a path analysis module, and an instruction update module; wherein, the output of the device acquisition module is connected to the status definition module, the output of the status definition module is connected to the instruction switching module, the output of the instruction switching module is connected to the path analysis module, and the output of the path analysis module is connected to the instruction update module.
[0022] The device acquisition module is used to acquire the coordinates, device type, and number of associated device groups of interactive devices in the exhibition hall, and to record the working status of each interactive device.
[0023] The state definition module is used to define the state coordination rules of related device groups in each exhibition hall based on the working state of the interactive devices in each exhibition hall and in combination with the working logic of the interactive devices.
[0024] The instruction switching module is used to determine the collaborative operation list for multiple devices working together in each exhibition hall based on the status coordination rules of interactive devices in each exhibition hall, combined with the update order and update time of the working status of associated device groups after the interactive devices trigger operation instructions.
[0025] The path analysis module is used to analyze the collaborative operation list, map the collaborative operation list to multiple interactive devices, and determine the visit path corresponding to the collaborative operation list by associating the status category of the device group after each mapping.
[0026] The instruction update module is used to compare the working status of interactive devices across devices according to the visit path corresponding to the collaborative operation list, determine the operation instructions updated for each interactive device in different associated device groups, and display each interactive device according to the updated content of the operation instructions.
[0027] The operating status is used to describe the actual operation of the interactive device. For example, the operating status of a game console may include the current number of players being 2, the game progress being Level 3, the number of players in the sensor reporting area being 5, and other descriptions indicating that the device is currently running.
[0028] In the current solution, the system core no longer responds to single on / off commands, but maintains a unified environmental state, such as a movie playing, a game in progress, or an audience watching—states that directly indicate interaction. At this point, any operation from any terminal, such as a tablet control panel or sensors, will attempt to change this global state. Upon receiving the intent, the system calculates a list of actions that devices, such as projectors, lights, and game consoles, need to perform, and coordinates them to switch to the new state in an orderly manner.
[0029] like Figure 2 As shown, when the device acquisition module records the working status of each interactive device, its implementation method also includes: taking the associated device group of the current interactive device as the verification subject, and identifying the working status and display requirements of each associated device group under coordinated work after the current interactive device triggers the operation command.
[0030] If the display requirements are met, the working status of the associated device group will be switched, and the working status of the current interactive device will be mapped to multiple associated device groups.
[0031] If the display requirements are not met, the process extends to the performance metrics of each associated device group, including projector bulb lifespan, LED screen refresh rate, server CPU / memory usage, network latency jitter, etc., to determine the current operating status of the associated device group. The environmental status of the current associated device group is then introduced, and the working status of the associated device group is correlated with the environmental status to obtain the frequency of occurrence of the performance metrics of each associated device group. The frequency of occurrence is then filled into the working status of each interactive device.
[0032] When combined with environmental conditions, these performance indicators will emphasize the parameters received by the sensors, such as the performance indicators of the sensor device group: the response time of the people flow sensor is ≤1s, and the accuracy of the temperature and humidity sensor is ±0.5℃ / ±5%RH; the environmental condition range is: temperature 18-25℃, relative humidity 40%-60%, and the illumination of the projected area is ≤100lx.
[0033] When acquiring the working status of associated device groups and interactive devices, interactive devices are generally devices such as touch screens, buttons, and joysticks, used to receive user operation commands and trigger the display of related images; associated device groups correspond to devices such as projectors, speakers, lights, LED screens, smoke machines, and water sprinklers, which are used to complete the playback and execution of content; the interactive device records the availability of each associated device group through stored data to comprehensively describe the working status of the interactive device, and the display requirements here indicate the content that can be played and displayed on the interactive device; when the display requirements are met, the central control system enables the associated device group of the current interactive device to execute the relevant content, and stores the devices involved in the execution in the form of working status data; if the display requirements are not met, it is necessary to record the fault conditions of the devices and collect these data in the working status of the interactive device.
[0034] At this point, the display requirements refer to the comprehensive standards of environmental conditions, equipment parameters, and system performance that must be met to achieve a specific interactive display effect; while the working status refers to the current operating parameters and status of each associated equipment group, ensuring that the content required by the current interactive device can be executed interactively.
[0035] At this point, the interactive device display emphasizes two-end interaction, or in the form of environmental state interaction, converting each terminal interaction into a state connection. After obtaining the terminal number and the number of people in the exhibition hall, it receives the number of machines controlled by each terminal. When any operation command is satisfied, it interacts with the working status of each machine involved in each operation command, forming a form of two-end mutual cooperation.
[0036] When implementing projection playback, it is necessary to control multiple lighting devices to darken the surrounding light and then use some lights and other sensors for dynamic display. At the same time, some devices may use multiple operating states, such as interactive devices in the form of game consoles, where multiple users operate them together. In this case, it is necessary to obtain the interaction states reported by multiple devices and interact with each machine according to its working state, forming a two-end collaborative closed loop of terminal operation and environment response.
[0037] In one embodiment of the present invention, in the state definition module, it is necessary to determine the parameters that each interactive device is running, as well as the parameters that the corresponding associated device group is running. Taking the operation command triggered by the interactive device as the starting point, as the trigger boundary of state coordination, the rules for how each interactive device triggers device coordination are defined.
[0038] like Figure 3 As shown, the implementation of the state definition module includes: responding to the working state of the interactive device, taking the interactive device as the starting point, the associated device group as the node, and the mapping relationship between the interactive device and the associated device group as the edge, to obtain the event connection graph between 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 its edges represent the logical relationship of the associated device group's work after the interactive device triggers the operation command. According to the current scene of the interactive device, the mapping relationship between the associated device group and the interactive device is described. For example, multiple associated device groups such as lighting device group, projection device group and sensor device group are connected, forming a form such as interactive device - associated device group 1 - associated device group 2. Based on the working state of each device in the current scene, a relatively complete action sequence is formed to complete the hierarchical sequential execution process of the associated device group.
[0039] For each node in the event connection graph, identify the collaborative work ratio of each node. The collaborative work ratio describes the weight allocation form under a certain operation command. For example, after a user clicks to play a movie, the system allocates the main light to 55% (responsible for the main brightness adjustment), ambient light to 30%, and auxiliary ambient light and dynamic light to 15% (responding to user interaction). The proportion values corresponding to multiple lights at this time are considered as the current collaborative work ratio. Based on the collaborative work ratio, identify the working status trajectory of the associated device group after the interactive device triggers each operation command, and set the state change trend of each node through the working status trajectory.
[0040] It should be noted that the collaborative work ratio represents the weight allocation ratio. At this time, each associated device group has a normal brightness value when working normally. This weight is used as a part of the associated device group for dynamic adjustment. For example, if the base brightness of the main light is expressed as 20%, the specific brightness of the corresponding device will be adjusted by multiplying the configured collaborative work ratio by the adjustment amount and adding the base value.
[0041] Furthermore, the collaborative work ratio will be set based on the device contribution weight and availability of each device. The collaborative work ratio = (device contribution weight × availability) / Σ (all device contribution weight × availability). In the movie playback scene, the projection contribution weight is 0.4, the main light is 0.3, and the sound is 0.3. The availability = normal working time / total running time × 100%.
[0042] Specifically, when it comes to the associated device groups for the lighting equipment group, projection equipment group, and sensor equipment group, the lighting equipment group mainly handles brightness, color, and dynamic effects of the lights; the projection equipment group determines the brightness, contrast, and coordinates of the currently playing content, and assigns weights to the corresponding associated device groups based on this data, explaining the necessity of adjusting the corresponding values during interaction; the sensor equipment group emphasizes the data collected in each area of the exhibition hall, assigning weights to the data according to the ratio of the number of data collected in each area to the total amount of data, and using this weight to explain the current working status of the equipment.
[0043] The above-mentioned working status trajectory represents the trajectory of the working status changes when the current associated device group is working. For example, if the current associated device group is the main light, then the changes in the brightness and color of the main light are detected at this time, and the changes in brightness and color over time are regarded as the working status trajectory. The status change trend is the trend of changes in brightness, color, light, resolution, contrast, and the coordinates after projection in the associated device group over time, which determines whether the current associated device group is working normally.
[0044] Based on the state change trends of each node, the correlation between the state changes of each node is identified, and the state coordination rules corresponding to the current associated device group are configured based on the correlation between the state changes of each node.
[0045] When configuring the state coordination rules for the current associated device group, the correlation of the current associated device group during state changes is used as the basis for setting the rules, based on the specific distribution of data collected by the lighting device group, projection device group, and sensor device group. The corresponding appropriate state coordination rules are found in the database. The implementation of the state coordination rules also includes: calculating the correlation between the state change trend of each node and the historical state change trend, according to the type of associated device group, using the rate of change of the state change trend. The Pearson correlation coefficient is used to calculate the correlation value between each associated device group, such as the correlation value between the lighting device group, projection device group, and sensor device group, to obtain the correlation calculation results. Based on the correlation calculation results, the state coordination rules are configured. When using the Pearson correlation coefficient to quantify the correlation value, the rate of change of the state change trend is set to the 0-minute average rate of change, and data from the same scene over the past 7 days are selected to determine the state of the current change trend relative to historical data.
[0046] At this point, the correlation between the state changes of each node is identified. This is achieved by standardizing the corresponding values in the state change trends, normalizing them, and then calculating the correlation value using the Pearson correlation coefficient. State coordination rules are then configured according to this correlation. State coordination rules are a collection of various device state combinations. For example, when an interactive device triggers an operation command related to lighting, these lights will automatically retrieve state coordination rules from the database based on the calculated correlation value. As shown below: the main light coordination ratio increases by 5% (correlation coefficient 0.92), the ambient light coordination ratio increases by 3% (correlation coefficient 0.85), and the dynamic light coordination ratio decreases by 2% (correlation coefficient 0.78). At this time, the lights corresponding to the currently associated device group are adjusted one by one. For the projection device, the brightness, contrast, and projected coordinates are dynamically adjusted to determine the position of the currently playing content. The state coordination rules retrieved by the sensors change the sampling density of data in each area to obtain a more accurate personnel tracking process.
[0047] Preferably, when identifying the collaborative working ratio of each node, the implementation method further includes: providing real-time feedback based on the current working state of the interactive device; if an operation command is received, controlling the associated device group to switch working states according to the working state of the interactive device, and obtaining the collaborative working ratio of the associated device group after the working state switch. The collaborative working ratio is then directly obtained from the database by specifying the weight allocation of the lighting device group, projection device group, and sensor device group under the corresponding operation command.
[0048] If the collaborative work ratio after the work status transition is greater than the target ratio, a weight update is triggered to re-acquire the collaborative work ratio and set the work status trajectory of the corresponding node based on the update time. A ratio greater than the target ratio indicates a deviation between the current associated device group's work and historical data. It's necessary to determine whether the currently set weight allocation ratio exceeds the collaborative work ratio set in the historical data. Exceeding this ratio may indicate a high load or risk situation for the corresponding associated device group, requiring increased monitoring of the relevant devices. If the ratio is less than the target ratio, it means the current weight allocation is relatively close to the historical data. In this case, no direct adjustment or improvement is needed; simply record the corresponding configuration value.
[0049] It should be noted that when the weight update is triggered, the collaborative work ratio is recalculated so that the deviation between the new ratio and the target state is ≤5%; if it still exceeds the target state, only the deviation is recorded and no further updates are made to prevent the data from being updated continuously and causing a loop risk.
[0050] If the value is less than or equal to the target state, the weight update will not be triggered. The time of obtaining the operation instruction will be used to set the working state trajectory.
[0051] The collaborative working ratio of operation commands will be defined in advance in the database according to the different commands, specifying the main control of the associated device groups under each operation. For example, the lighting device group mainly controls the form of the main lights, so as to describe the specific working status and progress process of each associated device group.
[0052] Preferably, the implementation method of setting the target state includes: analyzing the current working state trajectory and the historical working state trajectory using time series analysis; after time alignment, analyzing the correlation between the current working state trajectory and the historical working state trajectory; when the correlation value is the maximum, the collaborative working ratio of the corresponding working state trajectory is regarded as the current target state.
[0053] When setting target state differences, the working status of the current associated device group, such as lights, is first identified in a time-based manner. Then, the current working status trajectory is aligned with the historical working status trajectory. If the current working status trajectory represents the sequence of main light brightness changes over time, the historical working status trajectory represents the sequence of main light brightness changes in the same past scenario. At this point, the proportion of collaborative work that can occur under light changes is determined, and the Pearson correlation coefficient is used to calculate the relativity of the two working status trajectories. If, under the maximum correlation coefficient, there is a set collaborative work ratio between the current light change and the historical light change, it means that the current processing is the optimal collaborative work ratio value relative to the historical state. This value can be used to determine whether the current collaborative work ratio is set too high after acquisition, to prevent the load on some associated device groups from increasing.
[0054] It should be noted that the working status of multiple related device groups involved in the current processing will be synchronously mapped to the interactive device to illustrate how other devices work when the user touches the display screen or other interactive terminal, making it easier to monitor the usage of various devices in the exhibition hall.
[0055] In one embodiment of the present invention, in the instruction switching module, the collaborative work ratios described under multiple sets of state collaboration rules set in the state definition module are aggregated into a total collaborative operation list. When setting this table, multiple fields corresponding to the processing of the state definition module will be created in the table, such as the unique identifier of the exhibition hall, the unique identifier of the interactive device, the type of operation instruction, the description of the current working status of the associated device group, the state update time point, the current collaborative work ratio, the target state difference, whether the weight update is triggered, the new collaborative work ratio (if the update is triggered), the state and the record creation time, etc., to determine the current process of control and management of the interactive device and the associated device group.
[0056] like Figure 4As shown, the implementation of the instruction switching module includes: receiving the status coordination rules of the associated equipment groups in each exhibition hall, simulating the scene of each associated equipment group in the exhibition hall according to the update time and update order of the associated equipment groups, and determining the associated equipment group that responds after the operation instruction is executed.
[0057] The associated device groups that respond after execution are recorded, and the mapping relationship between each associated device group and the interactive device is recorded. Based on the available resource configuration of the associated device groups, the corresponding target scene mode is determined from the candidate scene modes.
[0058] Based on the target scenario, the working status of the associated device groups after execution is compiled into a collaborative operation list.
[0059] It should be noted that the simulated scenario describes how the associated devices work after receiving the current state collaboration rules. At this time, the resources that each associated device group can be configured in the corresponding scenario are determined. The resource configuration can represent the parameters that the current associated device group can be deployed in the corresponding scenario. The target scenario method represents the parameter set of multiple associated device groups in the corresponding scenario. By inputting these parameter sets into the collaboration operation list, the specific working parameters of the current associated device group can be obtained.
[0060] The aforementioned candidate scene layouts are preset schemes for the exhibition hall in the corresponding scenarios. Obtaining the target scene layout is to further determine the overall scheme of the current associated equipment group when it is working one by one. At this time, the target scene layout is directly selected from the candidate scene layouts by using the specific parameters of the associated equipment group.
[0061] When composing the collaborative operation list, the implementation method also includes: for the associated device groups in the collaborative operation list, a step-by-step self-check method is used to check the current associated device group and determine the probability of the associated device group's working status reaching the initial state when configured from one or more states; if the associated device group reaches the initial state, it means that the interactive device at the corresponding location has not performed the relevant operation, or the interactive device has not sent an operation command to the central control system, or the corresponding associated device group may be in standby mode and has not participated in the current collaborative interaction process; these all represent the specific working status of the associated device group in the exhibition hall.
[0062] At this point, the tiered self-test can check multiple devices according to the following: ① Power supply: voltage fluctuation ≤ ±5%; ② Connection: network latency ≤ 50ms, packet loss rate ≤ 1%; ③ Basic functions: projection image integrity ≥ 95%, sound volume 60-80dB; ④ Performance: CPU utilization ≤ 70%, etc. This self-test method gradually determines whether the associated device group is working properly in order to complete the subsequent visitor path setup under multi-device collaboration.
[0063] This probability is achieved by calculating the conditional probability of the associated device group transitioning from one 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 these conditions.
[0064] The aforementioned step-by-step self-test will progressively check the associated device group in terms of power supply, connectivity, and basic functions to determine whether the associated device group is usable.
[0065] Using the probability of reaching the associated device group as input, the state categories of each associated device are divided, and each associated device is described by the 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 baseline standby state of the device group, the potential active state will represent partial use of functions, in a pre-allocated state or low power consumption use, and the active state will be a state of actively participating in collaborative work, running with full functions and responding to user operations in real time.
[0066] When classifying these three state categories, 0.9 and 0.5 are used as thresholds, and [0.9, 1] is taken as the initial state type. If the value is greater than 0.9, it indicates that the corresponding associated device group is used infrequently during user interaction and remains in the initial configuration state for a long time, so direct monitoring is not required. [0.5, 0.9) is considered a potentially active state, indicating that the corresponding associated device group already has some functions involved in user interaction, which is a transitional stage of active user interaction and requires slight monitoring. As for (0, 0.5), it represents that the corresponding device is used relatively frequently and is used by many users, so timely monitoring is required. At this point, it is necessary to determine whether the device needs to be monitored in a timely manner according to the state category of the associated device group in order to complete the control of the overall exhibition hall environment.
[0067] In one embodiment of the present invention, the path analysis module needs to refer to the status categories of the associated device group, synchronize these status categories to the visit path, determine the current user's interest in different interactive items and displayed images, bind the devices that have interest in collaborative work, and regard the path of the corresponding bound device as the currently bound visit path.
[0068] like Figure 5 As shown, the implementation of the path analysis module includes: mapping the collaborative operation list to interactive devices to form path nodes, with each interactive device corresponding to an associated device group as an auxiliary node; then, by standardizing the path nodes based on the spatial location and status category of the associated device group and the interactive device, a path containing spatial coordinates is formed, and the visit path is output by filtering the path nodes.
[0069] Based on the device type of the interactive device, a basic interest score is set for each path node. An interest multiplier is then set based on the state category of the corresponding auxiliary node for each path node. The combined value of the interest multiplier and the basic interest score is considered the interest score for each path node. The interest multiplier is set based on the state category of any one of the active, potentially active, and initial states, with scores of 1.5, 1.2, and 0.8 respectively. The basic interest score is set according to the device type of the interactive device, such as 0.8 for interactive displays and 0.9 for immersive environments. This basic interest score is then used to calculate a weighted average with multiple associated device groups. The calculated value is then normalized to prevent the calculated interest score from being too high.
[0070] Furthermore, the basic interest score will be set according to the interaction frequency of the device and the pre-set display priority of the device. The display priority is a score value set in advance based on the deployed interactive devices, and the interaction frequency is calculated according to the number of times the corresponding device is used within an hour or other time period. That is, the basic interest score = interaction frequency weight (60%) + display priority weight (40%). The basic interest score is set to 0.9 for interaction frequency ≥ 10 times / hour, 0.8 for interaction frequency 5-10 times / hour, and 0.7 for interaction frequency < 5 times / hour. An additional 0.1 is added for core exhibit-related devices. At this time, the basic interest score for the current scenario is obtained by selecting 60% and 40% of the weights set by the interaction frequency and display priority, respectively.
[0071] Based on the interest scores of each path node, the shortest path connection method is used. The distance between each path node is used as a feature value, and the interest score is used as a weight to obtain the connected visitor path. The distance between each path node is calculated using Euclidean distance and normalized. Then, Dijkstra's algorithm is used as the shortest path algorithm. This shortest path represents the minimum weighted sum of the Euclidean distance and weights for the current path node while ensuring the exhibition hall is passable. The goal is to connect as many path nodes in the current exhibition hall as possible. This shortest path represents the path the user prefers to interact with during movement. Since the current goal is to obtain the path with the highest interest, when using the interest score as a weight, the weight is set to 1 minus the interest score value. This allows us to find the visitor path with the most concentrated relative interest using the shortest path algorithm.
[0072] Adjust the output visit path based on the number of path nodes that intersect with the visit paths in different scenarios.
[0073] The subsequent use of intersections to form a visitor path tends to identify path nodes of high interest across multiple scenarios and combine these path nodes into a single visitor path. When adjusting the output visitor path, the implementation includes: if the intersection contains only one path node, and these path nodes cannot form a relatively continuous visitor path, then the intersection represents the highest interest node connected to it from each scenario. This node will be output separately, forming a visitor path by connecting the current path node with its auxiliary nodes. If the intersection contains two path nodes, then the locations of these two path nodes in the current exhibition hall are identified. If these two path nodes are directly accessible within the exhibition hall, then these two path nodes are combined with auxiliary nodes and output as a visitor path, representing a local path of high interest across multiple scenarios. If two path nodes are difficult to traverse, an intermediate node is added between them. This intermediate node is located within the smallest enclosing circle defined by the two path nodes, and it is selected from multiple paths with the highest interest scores at their corresponding locations across various scenarios. The intermediate node is then connected to the two path nodes, and this connected path is considered the output visitor path. If the intermediate node cannot be connected, the process returns to the two path nodes, and a new intermediate node is obtained. This new intermediate node is iterated through according to its interest score until the two path nodes are connected via the intermediate node. This connected path is then used as the output visitor path. At this point, considering whether two points can be connected, a relatively localized visitor path is used to illustrate the main interactive devices attracting attention within the current exhibition hall.
[0074] It should be noted that the intermediate node is tried a maximum of 3 times. If it fails, a detour is adopted, connecting the adjacent path nodes with high interest scores one by one, and outputting the corresponding path.
[0075] If the intersection consists of three or more path nodes, then the shortest passable path is calculated by connecting the visitor paths, and this shortest path is output as the visitor path.
[0076] The instruction update module is used for the final update response. Based on the current visit path of interest to the user, it updates the operation instructions and the status of related interactive devices in real time according to the operation instructions of the devices. It continuously compares and updates the operation instructions triggered by the interactive devices to achieve synchronous display of device status.
[0077] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
