1. Introduction
This document lists the different functionalities available in the MIMBUS CONSTRUCT simulator.
We will first explain the generic features common to all our simulators.
Secondly, we will detail each instruction associated with a sequence of the simulator, that is to say how to accomplish the task assigned by the system in order to proceed to the next step during the simulation.
2. General Operation
2.1. Main Menu
When launching the application, the user is in a main room called the "reception hall", where a screen displays the simulator’s main menu.
The main menu allows the user to authenticate, select an exercise to perform, and view their results. At the end of each exercise, they will be teleported back to this room.
2.1.1. User Selection
-
Groups menu: allows filtering users by group. If no group is selected, all available users are displayed.
-
Users menu: allows selecting the user to authenticate.
-
VULCAN connection button: allows connecting or disconnecting to the VULCAN platform.
-
Settings button: allows opening the settings screen.
-
Exit button: allows exiting the application.
First, it is necessary to choose a user from those available on the main screen. A simple click on the user’s name displays a window in which you must enter their PIN code (four-digit number), configured in VULCAN.
The user can use the Groups filters on the right, allowing them to display only users from one or more classes created in VULCAN.
It is possible to display all users present in your VULCAN organization. However, those who are not assigned to a learning path corresponding to your simulator will appear grayed out. It will not be possible to log in with them on this simulator.
In offline mode, a demonstration user will be automatically selected.
2.1.2. Exercise Selection
-
Exercise menu: allows selecting the exercise to launch.
-
Modules menu: allows filtering exercises by module. If no module is selected, all available exercises are displayed.
This page displays the available exercises. A first click on an exercise displays its description. A second click validates the choice and launches the exercise. The tutorial allows you to familiarize yourself with the controls using a simplified scenario.
The user can use the Modules filters on the right to display only exercises from one or more categories.
In the exercise list, those already validated by the user are identified by a white crown in a colored circle. If connected to VULCAN, they can also choose to display only unvalidated exercises by deactivating the Show validated exercises button. Activating it allows viewing all exercises assigned to their group.
2.1.3. Difficulty Mode Selection
For compatible simulators, when selecting the exercise, the user can choose the difficulty level: Beginner, Advanced, or Expert. Depending on the exercises, the difficulty modifies the instructions and objectives. A click on the difficulty level launches the exercise. Already validated levels are identified by a white crown in a colored circle. For simulators that do not offer difficulty levels, a click on the Start button directly launches the exercise.
2.1.4. Results Screen
-
Exercise result: displays the overall score as a percentage (average of sensor scores, weighted by their respective coefficients defined in VULCAN), as well as whether the exercise was validated and its validation threshold.
-
Sensor results: display the evaluation criteria specific to each exercise.
-
Event history: indicates all significant events that occurred during the exercise. The timecode corresponds to the moment of the event, expressed in minutes and seconds elapsed since the start of the exercise.
At the end of the exercise, the user is teleported to the results screen, where they can view the overall summary, sensor details, and events that occurred during the exercise.
2.1.5. Settings Screen
From the home screen and in each simulator, the user can access the settings by clicking on the gear icon.
This interface allows you to change the language, adapt the interface, ergonomics, and accessibility according to your preferences, and ensure proper consideration of disabilities (colorblind filter, font adapted for dyslexic people, etc.). It is also possible to adapt the graphics. The Mimbus Bridge section allows you to enable or disable streaming via the MIMBUS BRIDGE application and adjust its quality if necessary. Finally, you will find information about the software version, your license number, and your organization identifier as referenced in the VULCAN LMS. This information may be requested when submitting a support request.
2.2. Controllers
2.2.1. Controllers
The application is compatible with all headsets supporting the OpenXR standard. Depending on the virtual reality headset used, the controllers and associated buttons differ.
Windows Mixed Reality
Valve Index
HTC Vive
Oculus Rift
3. Tutorial Module
3.1. Tutorial
In order to familiarize the user with the available interactions, a tutorial scenario can be launched from the module selection menu.
The aim of the tutorial is to teach the user the commands of the virtual reality equipment and the different metaphors used in the application in a clear and progressive way. It will take place in a neutral and uncluttered environment so as not to distract the user from the various actions expected.
A panel detailing the association between the user’s controllers and the actions will always be visible during the experience.
The tutorial is presented in the form of successive themed rooms, which the user will have to perform one after the other:
-
Moving around
-
Grabbing and moving an object
-
Interacting with an object
In each of the rooms, the user will learn an action (i.e., use of a button) in a dedicated space, and then will have to put this action into practice to leave the room and move on to the next. Once the three rooms are completed, the user will go through a final door to finish the tutorial.
3.1.1. Moving
Objective: to learn how to move around the virtual world and recognize markers that indicate a specific location.
The user will learn to move by teleportation. To leave this first room, the user will be asked to teleport to the next room.
By pressing the "Teleportation" button, it is possible to initiate a teleportation. As long as the button is held down, you can choose the teleportation destination. When you release the button, the teleportation will be performed.
A parabolic pointer coming out of the controller will then be visible, symbolizing the path taken during a teleportation. If teleportation is possible, this pointer is violet; if not, it is red.
3.1.2. Picking Up/Moving an Object
Objective: To learn to pick up an object, release it and place it on a magnetized area, and to recognize the associated visual feedback.
The user will be invited to bring their hand close to an object, visualize the associated visual feedback (blue outline), then pick up the object using the associated button and drop it onto a designated area on a second display.
Once this action is completed, the user will be prompted to exit the room by opening a door, giving them the opportunity to use the "Grab an item" interaction again on the handle.
3.1.3. Action/Using a Tool
Objective: To learn how to interact with tools or buttons, and recognize the associated visual feedback.
The user will be asked to interact with an object on a display (the object will be surrounded by a yellow outline indicating the possibility of activating it) and activate it using the associated button.
To exit the tutorial, the user will have to move to the back of the room and press the elevator button using the "Interact" button. A fade to black will return the user to the lobby.

5.1.2. Scenario Progress
The user begins the scenario next to a van with a bucket, in the parking lot of a pharmacy. They are close to a Low Voltage Main Switchboard (LVMS) room and facing their manager.

The user must first become aware of the task to be performed by speaking to their superior. A breakdown affects a luminaire near the LVMS and the user will have to replace its bulb safely.
The user must go talk to the customer to obtain more information, they can in particular ask them for the luminaire documentation which specifies the type of bulb to replace, here an E27 bulb.

A cabinet containing all the available PPE is present in the van. To enter, simply touch the side sliding door and press the interaction trigger. It will be necessary to equip the PPE by touching them and then pressing the interaction trigger:
-
Insulated gloves
-
Hard hat (then lower the visor)
-
High-visibility vest

An inventory can be opened by pressing the X or A buttons on the left or right controllers respectively. Objects can be dropped onto the bubbles that appear and then retrieved from these same bubbles. It will be necessary to store in the inventory:
-
The insulating mat
-
Insulated screwdriver
-
Voltage detector (VD)
-
Circuit breaker lockout
-
Lockout padlock
-
LED E27 replacement bulb

The user must go to the LVMS room, an electrical panel is opposite the door while the technical documentation of the LVMS can be consulted on the right. It is specified in the documentation that the Q34 contactor controls the power supply to the exterior parking lot luminaires. It will therefore be necessary to turn it off and lock it out.

First of all, the insulating mat must be placed on the floor in front of the cabinet.

The user can then open the cabinet door and turn off the Q34 contactor. Once turned off, grasp the circuit breaker lockout from the inventory and place it on the Q34 contactor. The lockout padlock can then be placed on the lockout to block interaction with it.

It will now be necessary to grasp the insulated screwdriver to unscrew the faceplate in front of the contactors. This will provide access to the terminals to check the correct power-off.

Once the faceplate is unscrewed and removed from the front, it can be placed on the ground.
You must now grab the VD and test for the absence of voltage at the contactor output. To do this, you must start with a VD self-test to verify its proper functioning. This involves touching the two tips together and confirming with the LEDs and a sound that the device is functioning correctly.

It is then necessary to place the VD tips on different terminals in pairs to check for the presence of current:
-
Input phase (top right of the contactor) and earth: Voltage is present
-
Input neutral (top left of the contactor) and earth: No voltage
-
Output neutral (bottom left of the contactor) and earth: No voltage
-
Output phase (bottom right of the contactor) and earth: No voltage

This demonstrates the absence of current at the contactor output. You must now perform another self-test of the device to confirm that it is still working and thus validate the latest absence of voltage measurement.
The user must now replace the faceplate, screw the two screws at its ends, and then close the LVMS door.

The user must go out and lift the upper cover of the luminaire to remove the bulb. They can store it in their inventory, place the new LED E27 bulb in the place of the old defective bulb, and then replace the cover.

They must then return to the LVMS room, remove the lockout padlock and the circuit breaker lockout and rearm the latter to turn the parking lot lighting back on before closing the door.
Once this is done, they can remove the insulating mat and put it back in their inventory.
The customer must be notified of the end of the intervention, after which it is necessary to go back to the manager and ask for the self-check sheet.

Filling it out ends the exercise.

-
Circuit breaker lockout
-
Lockout padlock
-
Replacement green cross illuminated sign

The user must go to the LVMS room, an electrical panel is opposite the door while the technical documentation of the LVMS can be consulted on the right. It is specified in the documentation that the Q33 contactor controls the power supply to the illuminated cross. It will therefore be necessary to turn it off and lock it out.

First of all, the insulating mat must be placed on the floor in front of the cabinet.

The user can then open the cabinet door and turn off the Q33 contactor. Once turned off, grasp the circuit breaker lockout from the inventory and place it on the Q33 contactor. The lockout padlock can then be placed on the lockout to block interaction with it.

It will now be necessary to grasp the insulated screwdriver to unscrew the faceplate in front of the contactors. This will provide access to the terminals to check the correct power-off.

Once the faceplate is unscrewed and removed from the front, it can be placed on the ground.
You must now grab the VD and test for the absence of voltage at the contactor output. To do this, you must start with a VD self-test to verify its proper functioning. This involves touching the two tips together and confirming with the LEDs and a sound that the device is functioning correctly.

It is then necessary to place the VD tips on different terminals in pairs to check for the presence of current:
-
Input phase (top right of the contactor) and earth: Voltage is present
-
Input neutral (top left of the contactor) and earth: No voltage
-
Output neutral (bottom left of the contactor) and earth: No voltage
-
Output phase (bottom right of the contactor) and earth: No voltage

This demonstrates the absence of current at the contactor output. You must now perform another self-test of the device to confirm that it is still working and thus validate the latest absence of voltage measurement.
The user must now replace the faceplate, screw the two screws at its ends, and then close the LVMS door.

To reach the illuminated sign, the user will have to use the van’s bucket.

Once on board, pressing the left joystick allows moving up or down. The emergency stop button on the right allows skipping the animation for those prone to motion sickness.

They must first unplug the sign, then unscrew the two screws holding it to the facade.

The cross can then be removed, placed in the inventory and replaced by the new one stored in the inventory.

They must then lower the bucket using the joystick and return to the LVMS room. The lockout padlock and circuit breaker lockout can be removed and the latter must be rearmed to turn the sign lighting back on before closing the door.
Once this is done, the insulating mat can be removed and put back in your inventory.
The customer must be notified of the end of the intervention, after which it is necessary to go back to the manager and ask for the self-check sheet.

5.3.2. Scenario Progress
The user begins the scenario next to a van with a bucket, in the parking lot of a pharmacy. They are close to a Low Voltage Main Switchboard (LVMS) room and facing their manager.

The user must first become aware of the task to be performed by speaking to their superior. A breakdown affects a high projector on the facade of the pharmacy and the user will have to replace a bulb safely.
The user must go talk to the customer to obtain more information, they can ask them for the projector documentation which allows in particular to know the type of bulb to use.

A cabinet containing all the available PPE is present in the van. To enter, simply touch the side sliding door and press the interaction trigger. It will be necessary to equip the PPE by touching them and then pressing the interaction trigger:
-
Insulated gloves
-
Hard hat (then lower the visor)
-
High-visibility vest
-

An inventory can be opened by pressing the X or A buttons on the left or right controllers respectively. Objects can be dropped onto the bubbles that appear and then retrieved from these same bubbles. For ecological reasons, it will be necessary to replace the defective halogen R7s bulb with a LED R7s bulb. It will be necessary to store in the inventory:
-
The insulating mat
-
Insulated screwdriver
-
Voltage detector (VD)
-
Circuit breaker lockout
-
Lockout padlock
-
LED R7s Bulb

The weather is very windy and makes the intervention at height with the bucket dangerous. The user will have to report this risk to their manager by first announcing they have a problem, which will result in its reduction. If the user does not report this danger, climbing on the bucket will result in a fall and a fatal outcome to the exercise.

The user must go to the LVMS room, an electrical panel is opposite the door while the technical documentation of the LVMS can be consulted on the right. It is specified in the documentation that the Q43 contactor controls the power supply to the facade lighting. It will therefore be necessary to turn it off and lock it out.

First of all, the insulating mat must be placed on the floor in front of the cabinet.

The user can then open the cabinet door and turn off the Q43 contactor. Once turned off, grasp the circuit breaker lockout from the inventory and place it on the Q43 contactor. The lockout padlock can then be placed on the lockout to block interaction with it.

It will now be necessary to grasp the insulated screwdriver to unscrew the faceplate in front of the contactors. This will provide access to the terminals to check the correct power-off.

Once the faceplate is unscrewed and removed from the front, it can be placed on the ground.
You must now grab the VD and test for the absence of voltage at the contactor output. To do this, you must start with a VD self-test to verify its proper functioning. This involves touching the two tips together and confirming with the LEDs and a sound that the device is functioning correctly.

9. Scaffolding Safety Module
9.1. Free mode
Free mode allows the user to move freely around the scaffolding. All the dangers available on the scaffolding are present, and fatal outcomes occur if the user gets too close to one of the dangers.
The purpose of this exercise is to raise the learner’s awareness of the dangers linked to poorly assembled scaffolding; the user will not have the option of securing the dangers he encounters. His objective, defined by the trainer in Vulcan, will be to reach a target floor while spending a defined amount of time in the simulation.
The student can leave the exercise at any time by clicking on the cross on the tablet on his left wrist.
9.1.1. Exercise evaluation criteria
Floor goal: Reach the floor objective
Survival time: Exceed the time objective "Time to accident"
9.2. Reception exercises
The Reception exercises come in four variants:
-
Facade scaffolding (guided mode)
-
Facade scaffolding (assessment mode)
-
Multidirectional scaffolding (guided mode)
-
Multidirectional scaffolding (assessment mode)
In these exercises, the user must evaluate the quality of the scaffolding assembly and flag any flaws for correction.
In guided mode, the user is helped at every step and is invited to correct any mistakes as he goes along, in order to assimilate best practices.
In assessment mode, the actions to be performed are similar, but the user’s mistakes are checked at the end of the exercise instead.
9.2.1. Exercise evaluation criteria
Analysis: relevance of the user’s answers during the preparation phase
Scenario: validation of all the steps that make up the scenario
Dangers identification: relevance of the user’s answers during the preparation phase
Execution time: ability to finish the scenario within a defined time
9.2.2. Preparing the intervention
At the start of the exercise, the mission order giver presents a briefing to the learner. On this screen, the user can use a button to have the briefing read aloud by the simulator’s built-in speech synthesis.
9.2.3. Selecting the weather
After validation, a weather bulletin appears. The user must determine whether the weather conditions are favourable for working on the site.
9.2.4. Preparing the equipment
Turn to the left and an open locker is visible with an interface enabling the user to choose the equipment to wear. If the user makes a poor choice, it is highlighted, and the user must correct the mistake before moving on to the next phase. Once the user has selected the equipment, click on the checkmark on the right of the screen.
The correct PPE is:
|
Hardhat with strap |
|
Protective glasses |
|
Ear protectors |
|
Coveralls |
|

|
Safety boots |
|
Harness |
9.2.5. Selecting the scaffolding
The user is automatically teleported to the site, facing two scaffoldings. He must choose the one that corresponds to the exercise specified during the briefing by teleporting to its dedicated marker.
9.2.6. Securing access
Before his intervention, the user must secure access to the scaffolding under reception.
The PPE selection screen appears and the user must pick up the caution tape by clicking the interaction button. It must then be placed at the entrance of the scaffolding to block access, by pointing at the location and clicking the interaction button again.
For multidirectional scaffolding, the tape must be positioned in front of the steps of the first level.
9.2.7. Checking the anchors
The user will then confirm that the scaffolding anchors are correctly positioned. To do this, he can view the scaffolding plan and visually check compliance. To help with this step, a "highlight anchors" button will highlight the anchors in blue.
9.2.8. Identifying dangers
Here, the aim is to methodically identify all scaffolding assembly flaws, floor by floor. All flaws must be identified before the user is allowed to move up to the next floor. Faults are generated randomly according to the instructions given by the trainer on the Vulcan platform, so each session is different for each user. Using a laser, the user will highlight the parts he considers to be defective or poorly assembled. The parts selected by the user appear highlighted in cyan.
It is during this phase that correction occurs in Guided mode: if some flaws have not been identified by the user, the trap door will not open, and the forgotten flaws will be highlighted in red, with a message indicating the mistake. The student must correct all his mistakes before being able to reach the next level.
Once the user has identified all the flaws on a floor, he moves on to the next floor by using the ladder and going through the trap door.

9.3.6. Arriving on site
The user is automatically teleported to the site, facing two scaffoldings. He must choose the one that corresponds to the exercise specified during the briefing by teleporting to its dedicated marker.
Before climbing onto the scaffolding, the user must ensure that its specifications comply with the requirements of the trade chosen at the start of the exercise. The user must read the sign to verify that the maximum load is allowed:
-
Finishing: scaffolding bearing 200kg/m² or more
-
Construction studies: scaffolding bearing 150kg/m² or more
-
Structural work: scaffolding bearing 600kg/m² or more
-
Wood framing: scaffolding bearing 450kg/m² or more
If the maximum load indicated on the sign is not sufficient for the user’s intervention, the value is automatically corrected so the exercise can continue.
9.3.7. Climbing the scaffolding
The user can now climb the scaffolding. The simulator will evaluate his ability to move around safely, in particular his ability to close each trap door behind him. The user must move to the work area indicated by a red icon.
9.3.8. Clearing obstacles
On the way to his objective, the user may encounter obstacles: heavy loads or materials blocking the passage. In this case, he will have to point at the object and click the interaction button to put it back in its place.
9.3.9. Moving to the purple circle
Once he has reached the intervention site, the user must walk to the purple circle. A sound confirms that the work went well.
9.3.10. Climbing down
The user must then climb down the scaffolding, always respecting all the safety rules. It is impossible to teleport from the top of the scaffolding. Move to the purple circle where the exercise started, and the user will then be teleported to the locker room where the results are displayed. The exercise is now complete.
9.4. Evaluation / Exercises in evaluation mode
In evaluation mode, the user receives no hints, and mistakes are checked at the end of the exercise. The evaluation criteria are as follows:
Analysis: relevance of the user’s answers during the preparation phase
Scenario: validation of all the steps that make up the scenario
Dangers identification: ability to recognize assembly flaws and obstacles
Execution time: ability to finish the scenario within a defined time
For the facade and multidirectional scaffolding evaluation, the user is required to find all the flaws, but no hints are given. If the user misses a flaw, it is considered a fatal error, and the evaluation is immediately stopped and the student fails. Once the user has completed all seven floors, he moves to the purple circle at the end of the scaffolding to be teleported to the locker room where the results are displayed.
9.5. Vulcan exercise settings
The default exercise settings cannot be modified, but it is possible to create editable copies of the exercises on Vulcan, and then modify the parameters. This allows the trainer to change the weighting of each parameter’s score (coefficient) based on different criteria. The parameters that can be modified are as follows:
Exercise name: allows the exercise name to be modified as it will be displayed in the simulator
Difficulty: corresponds to the exercise level; it is important not to modify this parameter when copying a default exercise (beginner=free mode, advanced=guided mode, expert=evaluation mode)
Validation threshold: minimum score required to pass the exercise
Inclusion threshold: score below which the exercise result will not be taken into account
9.5.1. Sensors
This table shows how to configure the sensors and their target minimum and maximum allowed values.
Min |
Target |
Max |

Floor objective |
0 |
Number of floors the user must reach to pass the exercise |
7 (there are 7 floors) |
Time (before an accident) |
The minimum time in seconds the user must spend in the exercise; anything below this will result in 0 |
Duration of the exercise in seconds from which the score will be 100% |
Unlimited, but must be set to a number |
Reception and Usage |
|||
Execution time (seconds) (applies only to Reception and Usage) |
0 |
anything below this threshold will result in a score of 100% |
any time spent on the exercise above this value, which will result in 0% |
The non-adjustable sensors are as follows:
-
Analysis
-
Securing
-
Identification
9.5.2. Simulation variables
It is possible to modify certain variables in the editable copy of the exercise in order to adapt to the exercise’s difficulty and complexity. They are as follows:
-
Defects on floor (+ floor concerned): number of defects randomly generated on the floor concerned.
-
Enable fatal errors: when this function is activated, a fatal error occurs if the user has forgotten to identify a fatal error on the current scaffolding floor
-
Obstacle on floor (+ floor concerned): number of obstacles to randomly generate on the floor concerned.
