Through such a scheme design, the present application can enable the user to actively operate the element model to complete the experimental process and output the experimental evaluation result based on the actual operation of the user. Thus, the user can intuitively understand the experimental principle and master the experimental operation process in the process of actively operating the element model, and significantly improve the user experience.

[0079] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be introduced in detail below.

[0080] Overview of Application Scenarios

[0081] The simulation-based experimental evaluation method of the embodiments of the present application is applicable to electronic devices capable of running platform software, such as personal computers, tablet devices, smart phones, etc., so that the electronic devices can perform operations such as selecting experiments and executing update events in response to the user's instructions when the user inputs corresponding instructions to the electronic devices, so as to enable the user to actively operate the element model to complete the experimental process and output the experimental evaluation result based on the actual operation of the user, so that the user can intuitively understand the experimental principle and master the experimental operation process in the process of actively operating the element model, and improve the user experience.

[0082] Exemplary Method

[0083] The simulation-based experimental evaluation method according to the exemplary embodiments of the present application will be described below with reference to Figure 2 It should be noted that the above application scenarios are only shown for the purpose of facilitating understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0084] Figure 2 A flowchart of a simulation-based experiment evaluation method according to another embodiment of the present application is schematically shown. Please refer to Figure 2 The simulation-based experiment evaluation method according to the embodiments of the present application can include the following steps:

[0085] In step 201, in response to receiving an experiment selection instruction sent by a user for a target experiment, an experiment operation interface corresponding to the target experiment is output. In the embodiments of the present application, the target experiment refers to an experiment item that the user needs to learn or take an exam, which can be, for example, an electrical experiment, a biochemical experiment, an optical experiment, etc., and the actual application can be determined, which is not limited herein.

[0086] The experiment selection instruction refers to an instruction generated by the user when selecting a target experiment. In some embodiments, the user can first log in to a platform for implementing the simulation-based experiment evaluation method using an account name and a password. After the platform successfully compares the account name and the password, an experiment selection interface is output. The user can select each experiment item displayed on the experiment selection interface according to actual needs, so as to input an experiment selection instruction to an electronic device running the platform. For example, if the electronic device is a computer, the experiment selection instruction can be input through a left mouse button. If the electronic device is a tablet computer or a smart phone, the experiment selection instruction can be input through a user's finger on the screen of the electronic device, and the actual application can be determined, which is not limited herein.

[0087] In response to the experimental selection instruction, an experimental operation interface corresponding to the target experiment is displayed on the device screen of the electronic device for the user to view. In the embodiments of the present application, the experimental operation interface includes one or more model elements associated with the target experiment. In some embodiments, the one or more model elements can include, but are not limited to, an experimental apparatus model associated with the target experiment and an apparatus adjustment component on the experimental apparatus model. For example, assuming that the target experiment is an electrical experiment, the experimental apparatus model can be a sliding rheostat, and the apparatus adjustment component can be a sliding piece on the sliding rheostat. In addition, in some embodiments, the experimental operation interface can also include, but is not limited to, an experimental instruction model corresponding to the target experiment and an experimental bench model for placing the experimental apparatus model. It can be understood that the experimental instruction model can be used to show the user the experimental operation content and the related experimental data input by the user, and the experimental operation content can include, but is not limited to, the experimental apparatus name required by the current experiment and the experimental operation steps, etc., which need to be determined according to the actual application, and the present application does not make any limitation here. In addition, the experimental bench model can be a three-dimensional experimental bench, and the user can complete the operation of the related experimental apparatus model within the range of the experimental bench model, view the experimental operation content in the experimental instruction model, and input the related experimental data in the experimental instruction model.

[0088] In some embodiments, assuming that the platform for implementing the simulation-based experimental evaluation method is an experimental examination platform, the experimental operation interface can also have a countdown module for displaying and prompting the user the remaining time of the experimental examination in such a scenario.

[0089] In step 202, in response to an update event initiated by the user for the experimental operation interface, the experimental operation interface is updated. The update event includes updating one or more model elements. In some embodiments, the update event includes, but is not limited to, a view switching interaction event and an experimental operation interaction event. The view switching interaction event is used to switch the operation view of the user, and the experimental operation interaction event is used to update the coordinate position of the experimental apparatus model and / or the apparatus adjustment component and update the performance state of the simulation experimental apparatus in the experimental apparatus model.

[0090] It can be understood that the virtual simulation technology can simulate the actual operation environment and experiment process through technical means such as graphic rendering, sound simulation, physical engine, etc. The experiment operation interface of the present application can be a high-precision three-dimensional laboratory scene simulated by virtual simulation technology. The experimental equipment models and equipment adjustment components in the scene are also modeled by three-dimensional high-precision modeling, one-to-one restoration of experimental equipment in the laboratory, and can simulate the physical, chemical or biological properties of the experimental equipment. Therefore, the viewing angle position in the three-dimensional laboratory scene can be configured and modified according to user needs and experiment requirements, so as to enable the user to observe the appearance structure and performance state changes of the experimental equipment models and equipment adjustment components from multiple viewing angles, such as oblique viewing angle, overhead viewing angle, normal viewing angle, near viewing angle, far viewing angle, etc.

[0091] In addition, in the embodiment of the present application, when entering the experiment operation interface, the experimental equipment models associated with the target experiment can be displayed at the preset initial coordinate position on the experimental table model, and the equipment adjustment components are also displayed at the preset origin position on the experimental equipment model. In response to the experiment operation interaction event initiated by the user for the experiment operation interface, the coordinate position of the experimental equipment model is updated to a coordinate position inconsistent with the preset initial coordinate position, and / or the coordinate position of the equipment adjustment component is updated to a coordinate position inconsistent with the preset origin position. In the case of updating the coordinate position of the experimental equipment model, the contact, collision, reaction or connection relationship between the experimental equipment models can be changed, thereby enabling the performance state of the simulated experimental equipment in the experimental equipment model to be updated.

[0092] In step 203, the evaluation result associated with the target experiment is determined based on the update event. It can be understood that each update event will contain at least one operation step to complete the update event based on the at least one operation step. In the embodiment of the present application, each operation step in the plurality of update events in the experiment process can be compared with the standard experiment step to determine whether each operation step of the user is the same or substantially the same as the standard experiment step. Each standard experiment step can correspond to a score point, so as to determine the evaluation result associated with the target experiment.

[0093] The experiment operation interface corresponding to the target experiment and containing one or more model elements associated with the target experiment is output in response to receiving an experiment selection instruction sent by a user for the target experiment. Based on this, the scheme of the present application updates the experiment operation interface in response to an update event initiated by the user for the experiment operation interface. In some embodiments, the aforementioned update event can include an update to one or more model elements, so as to determine an evaluation result associated with the target experiment based on the update event. Through such a scheme design, the present application can enable the user to actively operate the element model to complete the experiment process and output the experiment evaluation result based on the actual operation of the user. In this way, the user can intuitively understand the experiment principle and master the experiment operation process in the process of actively operating the element model, and significantly improve the user experience.

[0094] In some embodiments, the experiment operation interaction event can include but is not limited to an operation prompt interaction event and a drag movement interaction event. Figure 3 The flowchart of the simulation-based experiment evaluation method according to another embodiment of the present application is schematically shown. Please refer to Figure 3 In the simulation-based experiment evaluation method shown in the embodiment of the present application, the drag movement interaction event can include:

[0095] In step 301, the pointer selection instruction of the user is monitored. For example, if the device operated by the user is a computer, the pointer selection instruction can be the instruction generated when the left mouse button is clicked; if the device operated by the user is a tablet computer, the pointer selection instruction can be the instruction generated when the user's finger clicks the touch screen. It can be understood that the generation method of the pointer selection instruction needs to be determined according to the actual application, and the present application does not make any limitation in this regard.

[0096] In step 302, if the pointer selection instruction is monitored, it is determined whether to update the model state of the experiment equipment model or the equipment adjustment component according to the position where the pointer selection instruction occurs. The model state includes a static state and a dynamic state.

[0097] Specifically, when determining whether to update the model state of the experimental equipment model, it can be first judged whether the occurrence position of the pointer selection instruction is within the coordinate position range of the experimental equipment model. It can be understood that the coordinate position range of the experimental equipment model can be regarded as the space range surrounded by the outer contour of the experimental equipment model. For example, if the device operated by the user is a computer, the user clicks the left button in the space range surrounded by the outer contour of the experimental equipment model by the mouse, which can be regarded as that the occurrence position of the pointer selection instruction is within the coordinate position range of the experimental equipment model. Further, if the occurrence position of the pointer selection instruction is within the coordinate position range of the experimental equipment model, the model state of the experimental equipment model is updated from the static state to the motion state in response to the pointer selection instruction, indicating that the current experimental equipment model has been selected and is ready to move.

[0098] On the other hand, when determining whether to update the model state of the equipment adjusting component, it can be first judged whether the occurrence position of the pointer selection instruction is within the coordinate position range of the equipment adjusting component. It can be understood that the coordinate position range of the equipment adjusting component can be regarded as the space range surrounded by the outer contour of the equipment adjusting component. For example, if the device operated by the user is a computer, the user clicks the left button in the space range surrounded by the outer contour of the equipment adjusting component by the mouse, which can be regarded as that the occurrence position of the pointer selection instruction is within the coordinate position range of the equipment adjusting component. Further, if the occurrence position of the pointer selection instruction is within the coordinate position range of the equipment adjusting component, the model state of the equipment adjusting component is updated from the static state to the motion state in response to the pointer selection instruction, indicating that the current equipment adjusting component has been selected and is ready to move.

[0099] In step 303, if it is determined to update the model state of the experimental equipment model or the model state of the equipment adjusting component from the static state to the motion state, the motion trajectory of the experimental equipment model or the equipment adjusting component is determined based on the pointer motion trajectory of the user.

[0100] In the embodiments of the present application, the pointer motion trajectory can be determined as the model motion trajectory of the experimental equipment model. At the same time, in response to the model state of the experimental equipment model being updated from the static state to the motion state, the equipment motion operation instruction is generated. Further, in response to the equipment motion operation instruction, the experimental equipment model is moved along the model motion trajectory, that is, the current experimental equipment model can move along the pointer motion trajectory of the user. According to the equipment state of the experimental equipment model, it is determined whether to generate an error operation prompt and / or a dangerous operation prompt in the process of moving the experimental equipment model along the model motion trajectory. For example, assuming that the current experimental equipment model is an evaporating dish, when it is determined to update the model state of the evaporating dish from the static state to the motion state, the equipment motion operation instruction, for example, "START_DRAG-evaporating_dish", can be generated. However, if the equipment state of the above evaporating dish is the heated state, it can be understood that the evaporating dish in the heated state cannot be directly moved, and the evaporating dish in the heated state needs to be clamped by the crucible tongs before it can be moved, otherwise an error operation prompt and / or a dangerous operation prompt is generated. The error operation prompt and / or the dangerous operation prompt can include operation prompt information, which can be used to prompt the user to move the current experimental equipment model by using an auxiliary carrying model, which is an experimental equipment model that can carry the current experimental equipment model. Therefore, in this case, the occurrence position of the pointer selection instruction needs to be within the coordinate position range of the crucible tongs, and when it is determined to update the model state of the crucible tongs from the static state to the motion state, "START_DRAG-crucible_tongs" can be generated. Then, the crucible tongs are moved to the evaporating dish to establish a connection relationship with the evaporating dish, so that the evaporating dish can move along the crucible tongs, but at this time, "START_DRAG-evaporating_dish" does not need to be generated.

[0101] In another aspect, the component motion trajectory of the equipment adjustment component in the preset motion range can be determined based on the trajectory direction and the trajectory length of the pointer motion trajectory. In the embodiments of the present application, the preset motion range can be configured differently according to actual application conditions. For example, assuming that the current equipment adjustment component is a sliding vane on a sliding rheostat, the preset motion range corresponding to the sliding vane can be configured as a straight line segment corresponding to the magnetic cylinder of the sliding rheostat. Specifically, the preset motion range corresponding to the sliding vane can be determined by determining the coordinates of the two ends of the straight line segment. When it is determined that the model state of the equipment adjustment component is updated from the static state to the motion state, a component motion operation instruction can also be generated. In response to the component motion operation instruction, the current component motion operation instruction can move along the component motion trajectory determined based on the trajectory direction and the trajectory length of the pointer motion trajectory. When the sliding vane on the sliding rheostat moves, the resistance value of the sliding rheostat will also change accordingly.

[0102] For example, assuming that the current equipment adjustment component is a knob adjustment component, a virtual knob operation area can be output on the experimental operation interface in response to the generated component motion operation instruction. The virtual knob operation area is provided with an operation ball, the operation ball can move in a circle with the center point of the virtual knob operation area as the center, and the area range of the virtual knob operation area can be regarded as the preset motion range of the operation ball. Preferably, the virtual knob operation area can be a circular area. Further, it can be monitored whether the occurrence position of the pointer selection instruction of the user is within the coordinate position range of the operation ball. If it is monitored that the pointer selection instruction of the user occurs within the coordinate position range of the operation ball, the component motion trajectory of the operation ball in the virtual knob operation area can be determined based on the trajectory direction and the trajectory length of the pointer motion trajectory. For example, the knob adjustment component can be a zeroing screw of an ammeter. When the operation ball moves along the component motion trajectory in the virtual knob operation area, the pointer of the ammeter will also change the rotation angle accordingly, so as to achieve the zeroing effect of the ammeter.

[0103] It can be understood that if the pointer motion trajectory is always within the preset motion range, the direction and length of the component motion trajectory are consistent with the trajectory direction and the trajectory length of the pointer motion trajectory. However, if the pointer motion trajectory exceeds the preset motion range, the direction of the component motion trajectory is consistent with the trajectory direction of the pointer motion trajectory, and the length of the component motion trajectory needs to be determined after conversion of the trajectory length of the pointer motion trajectory. Exemplarily, assuming that the current equipment adjustment component is a slide on a sliding rheostat, the trajectory direction of the pointer motion trajectory is right, and the direction of the component motion trajectory is also right. However, the pointer motion trajectory exceeds the preset motion range, the vertical distance between the position of the pointer when the pointer stops and the preset motion range corresponding to the slide is 3 cm, and the trajectory length of the pointer motion trajectory is 5 cm, so the length of the component motion trajectory in the preset motion range corresponding to the slide converted from the trajectory length of the pointer motion trajectory is 4 cm. Exemplarily, assuming that the current equipment adjustment component is a zeroing screw of an ammeter, the trajectory direction of the pointer motion trajectory is counterclockwise, and the direction of the component motion trajectory of the operating ball is also counterclockwise. However, the pointer motion trajectory exceeds the virtual knob operation region, so the circular arc trajectory length and the circular arc central angle of the pointer motion trajectory can be determined with the center point of the virtual knob operation region as the center, and the circular arc length of the component motion trajectory of the operating ball in the virtual knob operation region is determined according to the circular arc central angle and the set rotation radius of the operating ball in the virtual knob operation region.

[0104] It can also be understood that the above exemplary description is only for better understanding of the scheme. In actual application, the way of determining the component motion trajectory of the equipment adjustment component in the preset motion range based on the trajectory direction and the trajectory length of the pointer motion trajectory is various, and a suitable way can be selected according to actual application, and the present application does not make any limitation in this aspect.

[0105] In step 304, until the pointer placement instruction of the user is monitored, the target placement position of the experimental equipment model or the equipment adjustment component is determined according to the occurrence position of the pointer placement instruction.

[0106] In the embodiments of the present application, the target placement position of the experimental apparatus model can be determined as follows: if the distance between the occurrence position of the pointer placement instruction and the assembled experimental apparatus is less than the preset distance threshold, it indicates that the coordinate position of the experimental apparatus model is very close to the assembled experimental apparatus, and thus the target placement position of the experimental apparatus model currently in the motion state is determined as the assembly coordinate position of the assembled experimental apparatus. It can be understood that the assembled experimental apparatus can adsorb the experimental apparatus model having the corresponding assembly relationship therewith when the experimental apparatus model approaches the assembled experimental apparatus, so as to complete the assembly of the experimental apparatus model and the assembled experimental apparatus, and thus the target placement position of the experimental apparatus model currently in the motion state can be determined as the assembly coordinate position of the assembled experimental apparatus. For example, it is assumed that the current experimental apparatus model is an evaporating dish, and the assembled experimental apparatus is the iron ring of the iron stand. It can be understood that the assembly coordinate position of the assembled experimental apparatus can be the upper position of the iron ring, so that the evaporating dish is assembled on the iron ring, and the iron ring can support the evaporating dish.

[0107] If the distance between the occurrence position of the pointer placement instruction and the assembled experimental apparatus is greater than or equal to the preset distance threshold, it indicates that the coordinate position of the experimental apparatus model is far away from the assembled experimental apparatus, and thus the target placement position of the experimental apparatus model currently in the motion state is determined as the occurrence position of the pointer placement instruction. In some embodiments, the experimental apparatus model can also be withdrawn to the initial position in the motion process. The actual application condition can be determined, and the present application does not make any limitation in this aspect.

[0108] On the other hand, the target placement position of the apparatus adjusting component can be determined as follows: if the occurrence position of the pointer placement instruction is within the preset motion range, the target placement position of the apparatus adjusting component currently in the motion state is determined as the occurrence position of the pointer placement instruction.

[0109] If the occurrence position of the pointer placement instruction is outside the preset motion range, the target placement position of the apparatus adjusting component currently in the motion state is determined as the projection position of the occurrence position of the pointer placement instruction in the preset motion range. For example, it is assumed that the current apparatus adjusting component is a slide on a sliding rheostat, the trajectory direction of the pointer motion trajectory is right, but the pointer motion trajectory exceeds the preset motion range, the vertical distance between the position of the pointer when the pointer stops and the preset motion range corresponding to the slide is 3 cm, and the length of the pointer motion trajectory is 5 cm, and thus the length of the component motion trajectory in the preset motion range corresponding to the slide converted from the length of the pointer motion trajectory is 4 cm, and thus the target placement position of the slide should be the position 4 cm right to the starting position.

[0110] If the projection position of the occurrence position of the pointer placement instruction is out of the preset motion range, the target placement position of the equipment adjustment component currently in the motion state is determined as the motion range endpoint close to the occurrence position of the pointer placement instruction in the preset motion range. Exemplarily, assuming that the current equipment adjustment component is a slide on a slide rheostat, the magnetic cylinder length of the slide rheostat is 4 cm, the trajectory direction of the pointer motion trajectory is to the right, but the pointer motion trajectory exceeds the preset motion range, the vertical distance between the position of the pointer when the pointer stops and the preset motion range corresponding to the slide is 3.5 cm, and the trajectory length of the pointer motion trajectory is 5.8 cm, the length of the component motion trajectory in the preset motion range corresponding to the slide converted from the trajectory length of the pointer motion trajectory should exceed 4 cm, but the magnetic cylinder length of the slide rheostat is 4 cm, so the target placement position of the slide should be the right endpoint in the preset motion range.

[0111] In particular, before determining the target placement position of the experimental equipment model or the equipment adjustment component according to the occurrence position of the pointer placement instruction, the equipment profile of the assembled experimental equipment can be updated from the original state to the highlighted state, so as to prompt the user that the experimental equipment model or the equipment adjustment component can generate an assembly relationship or a connection relationship with the assembled experimental equipment.

[0112] In the embodiment of the present application, after determining the target placement position of the experimental equipment model or the equipment adjustment component according to the occurrence position of the pointer placement instruction, the collision determination result can be determined according to the motion process of the current experimental equipment model, the coordinate position range of the experimental bench model and the coordinate position of the remaining experimental equipment models on the experimental bench model, wherein the motion process is the motion trajectory and / or the target placement position of the current experimental equipment model. Specifically, if the motion process of the current experimental equipment model intersects with the coordinate position range of the experimental bench model or the remaining experimental equipment models on the experimental bench model, it is determined that the current experimental equipment model collides with the experimental bench model or the remaining experimental equipment models on the experimental bench model. Further, if the collision determination result is collision, the collision object is recorded, wherein the collision object is the experimental bench model or the remaining experimental equipment model colliding with the current experimental equipment model, and whether to generate an error operation prompt and / or a dangerous operation prompt is determined according to the equipment state of the current experimental equipment model and the collision object.

[0113] Exemplarily, assuming that the current experimental equipment model is an evaporating dish in a heating state, in the movement process of the evaporating dish following the movement of the crucible tongs, if the movement trajectory and / or the target placement position of the evaporating dish directly intersects with the coordinate position range of the experimental bench model, it can be determined that the evaporating dish collides with the experimental bench model. However, at this time, since the evaporating dish is in a heating state, it cannot directly collide with the experimental bench model or be directly placed on the experimental bench model, and therefore an error operation prompt and / or a dangerous operation prompt can be generated to remind the user that the direct collision of the evaporating dish in the heating state with the experimental bench model or the direct placement of the evaporating dish in the heating state on the experimental bench model is an error operation behavior and / or a dangerous operation behavior.

[0114] In step 305, the performance state of the simulated experimental equipment is updated according to the target placement position of the experimental equipment model and / or the equipment adjusting component.

[0115] Exemplarily, when the target experiment is a weighing experiment, the simulated experimental equipment is a balance, the experimental equipment model is an object to be weighed and a weight, and the equipment adjusting component is a sliding weight, the weight difference between the object to be weighed and the weight placed on the two weighing pans of the balance can be determined according to the preset weight of the object to be weighed placed on one end of the weighing pan of the balance, the preset weight of the weight placed on the other end of the weighing pan of the balance, and the target placement position of the sliding weight, and then the tilt angle of the balance is updated according to the weight difference. It can be understood that the target placement position of the object to be weighed is the one end of the weighing pan of the balance, the target placement position of the weight is the other end of the weighing pan of the balance, and assuming that the current user operation is a computer, the mouse cursor can be set as a 2D picture of the weight or the object to be weighed dragging when the weight or the object to be weighed moves to the corresponding target placement position, and the 2D picture will move following the movement of the mouse cursor. In the movement process, it is judged whether the mouse cursor position is within the coordinate position range of the weighing pan, and if so, the user can be prompted in the form of highlighting the outline of the weighing pan that the weight or the object to be weighed has reached the coordinate position range of the weighing pan, and at this time the mouse left button can be released for placement operation. At this time, after the user releases the mouse left button, the position coordinates of the weight or the object to be weighed can be further corrected to enable the weight or the object to be weighed to reach the corresponding target placement position.

[0116] Specifically, the total weight of the weight placed on the one end of the weighing pan can be added to the reading of the sliding weight, and then the total weight of the object placed on the one end of the weighing pan is subtracted to obtain the weight difference, and if the weight difference is greater than zero, the image of the balance tilting n° within the preset frame number is output; if the weight difference is less than zero, the image of the balance tilting -n° within the preset frame number is output; and if the weight difference is equal to zero, the balance does not tilt. Wherein, n is greater than zero, and preferably n can be 10, which needs to be determined according to the actual application, and the present application does not make any limitation in this aspect.

[0117] Further, when the target experiment is a microscope experiment and the simulation experiment equipment is a microscope, the equipment adjustment component is a coarse focus knob and a fine focus knob, the rotation direction and the rotation angle can be determined according to the target placement position of the coarse focus knob and the fine focus knob and the original placement position of the coarse focus knob and the fine focus knob. The original placement position of the coarse focus knob and the fine focus knob can be regarded as the initial position before the coarse focus knob and the fine focus knob are updated to the target placement position, so that the rotation direction of the coarse focus knob and the fine focus knob can be determined by the difference between the original placement position and the target placement position, and the rotation angle of the coarse focus knob and the fine focus knob can be determined respectively. For example, it is assumed that the current user is operating a tablet computer, and the user generates a component motion operation instruction by clicking the coarse focus knob or the fine focus knob. The platform outputs a virtual knob operation area in the experiment operation interface in response to the generated component motion operation instruction, and the virtual knob operation area is provided with an operation ball that can move in the virtual knob operation area. The operation ball moves along with the movement of the finger after the user clicks the operation ball. Further, since three points can determine an angle, the center point a of the virtual knob operation area can be set as the first point, the original position b of the finger can be set as the second point, and the current position c of the finger can be set as the third point. The first line segment is obtained by connecting the points a and b, the second line segment is obtained by connecting the points a and c, and the included angle between the first line segment and the second line segment is the rotation angle of the coarse focus knob or the fine focus knob. According to the relative position of the first line segment and the second line segment, the rotation direction can be determined as clockwise or counterclockwise.

[0118] Since the rotation angle of the coarse focus knob and the fine focus knob has a linear relationship with the movement distance of the stage, the actual distance between the stage and the objective lens can be updated according to the rotation direction and the rotation angle, and then the height difference can be determined according to the actual distance and the preset distance. The preset distance is the distance between the objective lens and the stage when the microscope can clearly image, that is, the object distance. Since the blurring degree of the image is proportional to the height difference, the Gaussian blur number and the Gaussian blur radius of the output observation image can be determined according to the height difference. Specifically, the Gaussian blur number and the Gaussian blur radius can be determined by the following formula:

[0119] y = step * Math.Abs(d-v);

[0120] wherein Math.Abs(d-v) represents the above-mentioned height difference, which is determined by taking the absolute value of the difference between the actual distance and the preset distance. y is the numerical value of the blur number and the blur radius, and step is the sensitivity coefficient, which corresponds to the numerical value of the change of the blur number and the blur radius when the height difference changes by 1 cm, and then the observation image with the required blurring degree is obtained.

[0121] Further exemplarily, when the target experiment is a lens optical experiment, the simulation experiment equipment is a light screen, and the experiment equipment model comprises a light source, a convex lens, and a concave-convex mirror, the actual distance can be determined according to the target placement positions of the light source, the convex lens, the concave-convex mirror, and the light screen, and then the distance difference can be determined according to the actual distance and the preset distance, wherein the preset distance is the distance between the light source, the convex lens, the concave-convex mirror, and the light screen when the light screen can clearly image, and the Gaussian blur number and the Gaussian blur radius of the output observation image are determined according to the distance difference.

[0122] Further exemplarily, when the target experiment is a reflection optical experiment, the simulation experiment equipment is a mirror, and the experiment equipment model comprises a light ray output device, the mirror intersection point can be determined according to the target placement positions of the light ray output device and the mirror, and the reflected light ray image can be output according to the mirror intersection point and the normal vector of the mirror. Specifically, the image in front of the mirror can be obtained from the perspective of the direction from the mirror to the light ray output device, the obtained image is output to a rendering texture, and then the rendering texture is converted to conform to the optical characteristics of the plane mirror by using the shader technology in computer graphics to obtain a target image. Finally, the obtained target image is output to the mirror surface for display, so that the mirror surface can display an image conforming to the reflection law.

[0123] Further exemplarily, when the target experiment is an electrical experiment, the simulation experiment equipment is a lamp, and the experiment equipment model comprises a power supply, a wire, and at least one circuit component; wherein the circuit component comprises at least one circuit measuring device and a variable resistor; each circuit component has a terminal post, and the circuit diagram can be determined according to the target placement positions of the power supply, the wire, and the at least one circuit component. It can be understood that the target placement position of the wire is between the terminals of the power supply and the at least one circuit component, and is used to connect the power supply and the at least one circuit component to form a circuit.

[0124] When the wire is connected between each terminal, the wire model can be generated on the current terminal in the current application scenario if the occurrence position of the pointer selection instruction is within the coordinate position range of any terminal, by traversing the terminals on which the power supply and at least one circuit component can be connected and monitoring the pointer selection instruction at any terminal. It can be understood that the wire model belongs to the experimental equipment model, and the wire model can be preconfigured in the terminal model or generated on the terminal corresponding to the occurrence position of the pointer selection instruction, depending on the actual application. The present application does not make any limitation in this regard. Further, the model state of the wire model is updated from the static state to the motion state, so as to realize the dragging movement of the wire from the current terminal. In the wire movement process, other terminals that can be connected from the current terminal are further screened out, and the profile of the above other terminals is updated from the original state to the highlighted state, so as to prompt the user to drag the wire to the other terminal in the highlighted state for connection.

[0125] Further, all closed loops in the circuit diagram are traversed. Specifically, a graph data structure can be generated, a node on the graph is created for each power supply and each circuit component, and an edge connecting the nodes corresponding to two circuit components is added in the graph whenever the two circuit components are connected. Similarly, the edge between the nodes corresponding to two components is deleted whenever the two components are disconnected. When traversing, the node corresponding to the power supply is first found, and then the edge corresponding to the wire connected to the positive terminal of the power supply is traversed to find all closed loops in the circuit diagram. Among them, a closed loop must start from the positive terminal of the power supply and end at the negative terminal of the power supply, all circuit components on the loop can only appear once on the loop, and if there is a switch on the loop, the switch must be in the closed state.

[0126] Further, the current value and the voltage value of each circuit component and the lamp are determined based on each closed loop. Specifically, Kirchhoff's equation corresponding to each closed loop can be generated according to Kirchhoff's circuit law, and then the Kirchhoff's equation corresponding to each closed loop is solved to form a Kirchhoff's equation set, so as to determine the current value and the voltage value of each circuit component and the lamp. The current value and the voltage value of each circuit component and the lamp and the range of the circuit measuring device are used to update the indication interface of the circuit measuring device, such as the current meter and the voltage meter. The corresponding current value and voltage value are updated and displayed in the indication interface of the current meter and the voltage meter. Whether the range is exceeded or whether the connection is reversed can be determined through the indication interface of the current meter and the voltage meter, so as to determine whether to generate an error operation prompt and / or a dangerous operation prompt. The display brightness of the lamp is updated based on the current value and the voltage value of the lamp. The display brightness of the lamp can be updated according to the current value, the voltage value on the lamp, and the rated voltage and the rated current of the lamp.

[0127] Further exemplarily, when the target experiment is a biochemical experiment, the simulation experiment equipment is a measuring cylinder, and the experiment equipment model comprises a beaker, whether the liquid in the beaker is injected into the measuring cylinder can be determined according to the target placement positions of the beaker and the measuring cylinder. If the distance between the target placement positions of the beaker and the measuring cylinder is less than a preset distance threshold, the beaker is adsorbed to the opening of the measuring cylinder, and the liquid in the beaker is triggered to be injected into the measuring cylinder. If it is determined to be injected, the liquid level of the measuring cylinder is updated according to the liquid capacity and the size of the measuring cylinder. Wherein, the injection of the liquid can consider the bottom area of different containers. When pouring into a container with a small bottom area, the liquid level rises more, and when pouring into a container with a large bottom area, the liquid level rises less. Therefore, the maximum capacity of the container, the current capacity of the liquid and the bottom area of the container need to be recorded in the beaker, the measuring cylinder and other containers. The height of the liquid is calculated according to the current injected liquid capacity and the container bottom area. When the liquid is poured out, the height of the liquid level can be calculated according to the poured capacity and the container bottom area. When the liquid is poured in, the height of the liquid level can be calculated according to the poured capacity and the container bottom area.

[0128] In some embodiments, the aforementioned update event can further include a perspective switching interaction event, and the experiment operation interaction event comprises an operation prompt interaction event and a drag motion interaction event. Figure 4 The flowchart of the simulation-based experiment evaluation method according to another embodiment of the present application is schematically shown. Please refer to Figure 4 The simulation-based experiment evaluation method shown in the embodiments of the present application can comprise:

[0129] In step 401, the pointer coordinate position of the user is monitored. In the operation prompt interaction event, the pointer coordinate position of the user needs to be monitored in real time. Exemplarily, if the device operated by the user is a computer, the pointer coordinate position can be the mouse pointer position; if the device operated by the user is a tablet computer, the pointer coordinate position can be the position of the user's finger when clicking the touch screen. It can be understood that the determination method of the pointer coordinate position needs to be determined according to the actual application, and the present application does not make any limitation in this regard.

[0130] In step 402, the pointer shape is updated to the corresponding prompt cursor shape based on the pointer coordinate position. If it is monitored that the pointer coordinate position is within the coordinate position range of the current experiment equipment model, the pointer shape is updated to the prompt cursor shape matched with the operable mode of the current experiment equipment model. Exemplarily, if the pointer coordinate position is on the cover glass, the pointer shape is updated to the prompt cursor shape of the magnifying glass shape. Because the cover glass has a small area, it needs to be magnified when observing the experiment operation of "the cover glass is slowly covered on the slide from the liquid drop side".

[0131] On the other hand, if the pointer coordinate position is monitored to be within the coordinate position range of the equipment adjustment component of the current experimental equipment model, the pointer shape is updated to a prompt cursor shape matching the operable mode of the equipment adjustment component of the current experimental equipment model. For example, if the equipment adjustment component is a microscope power switch, the pointer shape is updated to a hand-shaped prompt cursor shape; if the equipment adjustment component is a terminal post, the pointer shape is updated to a wire-shaped prompt cursor shape.

[0132] In particular, in the view angle switching interaction event, if the pointer coordinate position is monitored to be within the coordinate position range of the observable equipment model in the experimental equipment model, the pointer shape is updated to an enlarged prompt cursor, which can be consistent with the above-mentioned magnifying glass-shaped prompt cursor shape or can be a cursor of other shapes, which are not limited in the present application.

[0133] In step 403, if the zoom-in confirmation instruction generated by the user within the coordinate position range of the observable equipment model is received, the experimental operation interface is updated to the model close-up interface corresponding to the observable equipment model in response to the zoom-in confirmation instruction. The observable equipment model can be exemplarily a current meter and a voltage meter. The pointer can be hovered to the dial position of the current meter or the voltage meter. After the zoom-in confirmation instruction is input, the platform updates the experimental operation interface to the model close-up interface of the current meter or the voltage meter in response to the zoom-in confirmation instruction, so that the user can clearly observe the reading on the current meter or the voltage meter.

[0134] In step 404, if the zoom-in restoration instruction generated by the user within the coordinate position range of the observable equipment model is received, the model close-up interface is updated to the experimental operation interface in response to the zoom-in restoration instruction.

[0135] In step 405, if the pointer selection instruction generated by the user within the coordinate position range of the equipment adjustment component is received, a partial display window of the observable equipment model corresponding to the equipment adjustment component is output in the experimental operation interface. For example, when adjusting the sliding rheostat, the voltage reading of the voltage meter needs to be observed while moving the sliding piece. After the circuit is correctly connected, the partial display window of the voltage meter is output in the experimental operation interface when the sliding rheostat sliding piece is dragged, and the dial position of the voltage meter is enlarged, so that the user can clearly observe the reading on the voltage meter. The partial display window disappears when the sliding piece is released.

[0136] It can be understood that the execution of step 405 is not strictly time-limited in sequence with the execution of steps 403 to 404. Step 405 or steps 403 to 404 can be executed according to the actually received instruction, which is not limited in the present application.

[0137] In some embodiments, after receiving the relevant experimental data in the experiment description model input by the user and receiving the experiment end instruction input by the user, the step of determining the experimental evaluation result is started to be executed. Figure 5 The flowchart of the simulation-based experiment evaluation method according to yet another embodiment of the present application is schematically shown in FIG. 6. As shown in FIG. 6, the simulation-based experiment evaluation method according to the embodiment of the present application can include the following steps. Figure 5 The simulation-based experiment evaluation method according to the embodiment of the present application can include the following steps.

[0138] In step 501, the state data array is determined based on each operation state data. The operation state data is the data recorded in the update event corresponding to each operation step, and the operation state data at least includes the equipment state, the operation time information and the position information of the model element after the update.

[0139] It can be understood that each experiment includes a plurality of experimental equipment models, each of which has its own equipment state, for example, a beaker records the type and volume of liquid in the beaker, and an evaporating dish records whether it is in a heating state. Each experimental equipment model also has its own coordinate position information. Each operation step performed in the update event can affect the operation state data of the experimental equipment model. Therefore, when the user performs an operation, all experimental equipment models in the current experiment can be traversed, and the operation state data of all experimental equipment models can be saved. The operation state data at least includes the operation time information and the position information of the model element after the update, and can also include the operation name and the equipment state, etc., thereby generating the operation state data ExperimentState corresponding to the operation. The obtained several operation state data ExperimentState are sequentially arranged according to the operation time, and the state data array List <experimentstate>.

[0140] In step 502, an experiment state condition is formed based on one or more component states.

[0141] In the embodiments of the present application, analysis can be performed based on the obtained state data array. Specifically, one important means of data analysis is to judge and filter the experiment state condition Condition, which is a description of the experiment data. The experiment state condition can be formed based on the component state ComponentCondition of a single experiment component model, or based on the component state ExperimentCondition of multiple experiment component models. For example, the closing of a switch can be regarded as an experiment state condition. In the experiment, a switch component is found, and the component state of the switch component stores the state of whether it is closed. If the switch state is closed in an operation state data ExperimentState, then the experiment state condition is satisfied, which is an experiment state condition based on the state of a single circuit component. In addition, for example, the experiment state condition can also be to judge whether a circuit is a series circuit. To do this, the connection state of all circuit components in the experiment needs to be judged. In this scenario, if the connection of the circuit in an operation state data ExperimentState is a series circuit, then it can be considered that the experiment state condition is satisfied, and the experiment state condition is an experiment state condition based on the state of multiple circuit components.

[0142] Further, for example, it is judged whether an operation step is to pour water into a beaker containing concentrated sulfuric acid, which is also an experiment state condition. This needs to be judged based on the previous and next operation state data ExperimentState to determine whether the experiment state condition can be satisfied. If the beaker in the previous operation state data ExperimentState contains only concentrated sulfuric acid, and the beaker in the next operation state data ExperimentState contains both concentrated sulfuric acid and water, then it can be judged that this is an operation step of pouring water into a beaker containing concentrated sulfuric acid, and the experiment state condition is satisfied, which is an experiment state condition OperationCondition running based on multiple operation state data ExperimentState.

[0143] Further elaboration, as an example, to determine whether a certain operation step is the step of adding water to a beaker containing concentrated sulfuric acid, it needs to be determined according to two continuous operation state data ExperimentState. Specifically, if the beaker only contains concentrated sulfuric acid in the last operation state data ExperimentState, and the beaker contains both concentrated sulfuric acid and water in the next operation state data ExperimentState, it can be inferred that the operation step is to pour water into the beaker containing concentrated sulfuric acid. At this time, the running experiment state condition OperationCondition is satisfied, and the running experiment state condition is an experiment state condition based on multiple operation state data ExperimentState.

[0144] It can be understood that the permutation and combination of different experiment state conditions can constitute a new experiment state condition. For example, the combination of the on-off switch experiment state condition and the series circuit experiment state condition can obtain a new experiment state condition, which is an on-off switch series circuit, which is a more complex experiment state condition. The permutation and combination of experiment state conditions to form a new experiment state condition is realized by operator overloading of the experiment state condition Condition class. By overloading the & |! operators of the Condition class, the expression condition1 & condition2 can return a new experiment state condition condition3. More complex expressions such as (condition1 |! codition2) & condition3 can also be supported.

[0145] In step 503, the target operation state data is determined in the state data array according to the experiment state condition. Through the experiment state condition, the target operation state data can be determined in the state data array List <experimentstate>Filter out the meaningful operation state data ExperimentState, i.e., the target operation state data.

[0146] In step 504, determine the experimental evaluation result according to the target operation state data, and the experimental evaluation result includes the experimental evaluation score, the error operation list, the dangerous operation list, and the experimental learning situation analysis.

[0147] According to the target operation state data, the correct operation judgment, the error operation judgment, the dangerous operation judgment, the experimental score judgment, and the experimental learning situation analysis can be realized, so that the experimental evaluation result including the experimental evaluation score, the error operation list, the dangerous operation list, and the experimental learning situation analysis can be formed. For example, if the operation state data of the user meets the experimental state condition of pouring water into a beaker containing concentrated sulfuric acid, the error operation judgment and / or the dangerous operation judgment are triggered, the operation step corresponding to the current operation state data is updated to the error operation list and / or the dangerous operation list, and the user can be reminded by a pop-up window or a message box in the experimental operation interface that this operation step is a dangerous operation and / or an error operation. When the experimental score is judged, it can be determined that the operation step of the user meets the experimental state condition of pouring water into a beaker containing concentrated sulfuric acid, so that the corresponding preset operation score point should not be scored.

[0148] In the experimental evaluation score in the experimental evaluation result, the final experimental score can be shown, and the preset operation score points that are scored and the preset operation score points that are not scored can be listed, and the accuracy can be further calculated. Therefore, the user's performance in different experiments can be comprehensively analyzed to give targeted optimization suggestions to improve the user's mastery of the experiment and improve the user's learning effect of the experiment.
