The present invention relates to training assessment and, more particularly, to training assessment relying on interactive computer simulations.
An interactive computer simulation system performs one or more interactive computer simulations. Each interactive computer simulation comprises one or more virtual simulated elements each representing an actual system (e.g., multiple virtual aircraft systems each representing an actual aircraft). Each interactive computer simulation provides a virtual computer generated environment and various tangible instruments (or controls) in a simulation station to allow enactment of different scenarios for the purpose of training one or more users (or trainees), using one or more of the virtual simulated elements, in the operation and/or understanding of the corresponding one or more actual systems. The virtual simulated element, or simulated element, is defined herein as a simulated system. The simulated element is a virtual version that simulates, to the extent required by the interactive computer simulation, behavior of an actual system. The various tangible instruments accessible to the one or more users in the simulation station replicate actual instruments or otherwise reproduce behavior of the actual instruments found in the actual system.
In order to properly train the users and allow them to improve, assessments are made considering different expected results.
The present invention aims at improving the quality and relevance of the assessments made in the context of interactive training computer simulations.

When multiple simulation stations 1100 are present in the system 1000, the monitoring station 1700 may present different views of the computer program management interface (e.g., to manage different aspects therewith) or they may all present the same view thereof. The computer program management interface may be permanently shown on a first of the screens of the monitoring station 1700 display module while a second of the screens of the monitoring station 1700 display module shows a view of the interactive computer simulation (i.e., adapted view considering characteristics of the second screen). The computer program management interface may also be triggered on the monitoring station 1700, e.g., by a touch gesture and/or an event in the interactive computer program (e.g., milestone reached, unexpected action from the user, or action outside of expected parameters, success or failure of a certain mission, etc.). The computer program management interface may provide access to settings of the interactive computer simulation and/or of the simulation station 1100. A virtualized monitoring station may also be provided to the user (e.g., through the GUI module 1150) on a main screen, on a secondary screen or a dedicated screen.
In some embodiments, the interactive computer simulation system 1000 comprises a debriefing station 1600. The debriefing station 1600 is sometimes referred to as a Brief and Debrief System (BDS). The debriefing station 1600 may provide functionalities also provided by the monitoring station 1700 in the context of debriefing past sessions thereat. For instance, when monitoring station 1700 and/or debriefing station 1600 functionalities are provided through the interactive computer simulation station 1100, the GUI module 1150/1650/1750 may further be used to monitor and control one or more ongoing or recorded interactive computer simulation (e.g., triggering/monitoring events and/or selecting a perspective from which to view the ongoing or recorded chain of events of one or more interactive computer simulation).
The simulation station 1100, the monitoring station 1700 and the debriefing station 1600 may be connected via a network 1400, via direct connections or a mix of direct and network connections. In the depicted example of
In the depicted example of
The memory module 1120 may comprise various types of memory (different standardized or kinds of Random Access Memory (RAM) modules, memory cards, Read-Only Memory (ROM) modules, programmable ROM, etc.). The network interface module 1140 represents at least one physical interface that can be used to communicate with other network nodes. The network interface module 1140 may be made visible to the other modules of the simulation station 1100 through one or more logical interfaces. The actual stacks of protocols used by the physical network interface(s) and/or logical network interface(s) 1142, 1144, 1146, 1148 of the network interface module 1140 do not affect the teachings of the present invention.
The variants of processor module 1130, memory module 1120 and network interface module 1140 usable in the context of the present invention will be readily apparent to persons skilled in the art.
A bus 1170 is depicted as an example of means for exchanging data between the different modules of the simulation station 1100. The present invention is not affected by the way the different modules exchange information between them. For instance, the memory module 1120 and the processor module 1130 could be connected by a parallel bus 1170, but could also be connected by a serial connection or involve an intermediate module (not shown) without affecting the teachings of the present invention.
Likewise, even though explicit mentions of the memory module 1120 and/or the processor module 1130 are not made throughout the description of the various embodiments, persons skilled in the art will readily recognize that such modules are used in conjunction with other modules of the simulation station 1100 to perform routine as well as innovative steps related to the present invention.
In the depicted example of
In some embodiments, the simulation mapping system 1800 comprises a local simulation mapping system 1800A, in each of the interactive computer simulation stations 1100, and a coordinating simulation mapping system 1800B for the interactive computer simulation system 1000. In some embodiments, the coordination aspects of the simulation mapping system 1800 are distributed between the different local simulation mapping systems 1800A. In some embodiments, the local aspects of the simulation mapping system 1800 are performed from the coordinating simulation mapping system 1800B (e.g., through access to a storage system 1500 and/or to the different elements of the interactive computer simulation system 1000).
In some embodiments, the simulation mapping system 1800B comprise a memory module similar to 1120, a network interface similar to 1140 and a bus similar to 1170, which have not been replicated on
The simulation mapping system 1800 may further comprise (not shown) an environment tracking module, which may be used to capture one or more feed of images and/or environmental data from the interactive computer simulation station 1100. For instance, the environment tracking module may comprise one or more 360-degree camera and/or a plurality of cameras throughout the interactive computer simulation station 1100 to provide a choice of perspectives therein. For instance, the perspectives offered through the cameras may be set to cover as many critical locations in the interactive computer simulation station 1100 (e.g., position of the hands of trainee(s), readings or settings on one or more of the instruments of the instrument module 1160 and/or determination of a position of one or more instruments, tracking of the trainee(s)' gaze or other body parts, etc. The environment tracking module may also comprise one or more sound recorders (e.g., for conversations in the simulation station as well as with outside elements), one or more thermometer, one or more biometric readers (e.g., trainee(s)' status readings, gaze detector, sleepiness detector, etc.), smoke or other visual impairment detector, etc.)
The interactive computer simulation system 1000 comprises a storage system 1500 for, among other aspects, collecting dynamic data in relation to the dynamic system and dynamic subsystems while the interactive computer simulation is performed. The dynamic data stored in the storage system 1500 comprises dynamic data necessary for the simulation mapping system 1800 as well as results from the processing and/or converting performed by the simulation mapping system 1800.
The interactive computer simulation station 1100 may comprise a graphical user interface (GUI) module 1150 that may be used to visualize virtual dynamic subsystems from the virtual simulated element. The GUI module 1150 may comprise one or more display screens such as a wired or wireless flat screen, a wired or wireless touch-sensitive display, a tablet computer, a portable computer or a smart phone.
Users of the interactive computer simulation system 1000 (e.g., users of the simulation stations 1100) interact in the interactive computer simulation to control a virtual simulated element in a computer generated environment of the interactive computer simulation system 1000 (e.g., instructors or experts, trainees such as a pilot and co-pilot, a driver, an operator, a surgeon, a flight investigator, a training analyst, a flight analyst, etc.). Examples of virtual simulated elements include a simulated aircraft system, a simulated ground vehicle system, a simulated spacecraft or space station system, a simulated control room system, unmanned vehicle or drone, simulated human mannequin, etc. Examples of virtual dynamic subsystems vary depending on the virtual simulated element. In the example of a simulated aircraft system, typical virtual dynamic subsystems may include virtual hydraulic systems, virtual communication systems, virtual display systems, virtual wiring systems, virtual in-flight entertainment systems, virtual fuel systems, virtual lighting systems, virtual rudder system, virtual flap system, virtual landing gear system, etc. In the example of a simulated living system, typical virtual dynamic subsystems may include blood system, digestive system immunity response system, lymphatic system, nervous system, biometric data such as temperature, blood pressure and other related physical data, etc. When a trainee or user is involved, actual measurements of biometric data may also be recorded (e.g., for subsequent correlation with other recorded data). For instance, biometric data from a pilot interacting in a computer simulation with one or more tangible instruments at the simulation station 1100 may be recorded (such as temperature, blood pressure and other related physical data). As a skilled person would appreciate, most virtual subsystems are directly or indirectly affected by interactions of the user with one or more tangible instruments that allow the user to interact (e.g., provide different commands in order to control the virtual simulated element) during the interactive computer system in the computer generated environment. Some other virtual subsystems may be affected by time elapsed during the interactive computer system and may further take into account the interactions of the user with one or more tangible instruments. For instance, in the example of a simulated aircraft system, a virtual aircraft structure subsystem may comprise one or more virtual mechanical components. Failure of any one of virtual mechanical components, or the virtual aircraft structure subsystem altogether, may be based on accumulated mechanical stress considering use time (e.g., number of flights and operating hours) and also based on maneuvers caused by the pilot manipulating the one or more tangible instruments.
The tangible instrument provided by the instrument modules 1160 are tightly related to the element being simulated. In the example of the simulated aircraft system, typical instruments include various switches, levers, pedals and the like accessible to the user for controlling the aircraft in the interactive computer simulation. Depending on the type of simulation (e.g., level of immersivity), the tangible instruments may be more or less realistic compared to those that would be available in an actual aircraft. For instance, the tangible instrument provided by the module 1160 may replicate an actual aircraft cockpit where actual instruments found in the actual aircraft or physical interfaces having similar physical characteristics are provided to the user (or trainee). As previously describer, the actions that the user or trainee takes with one or more of the tangible instruments provided via the instrument module 1160 (modifying lever positions, activating/deactivating switches, etc.) allow the user or trainee to control the virtual simulated element in the interactive computer simulation. In the context of an immersive simulation being performed in the interactive computer simulation system 1000, the instrument module 1160 would typically support a replicate of an actual instrument panel found in the actual system being the subject of the immersive simulation. In such an immersive simulation, the dedicated graphics processing unit 1132 would also typically be required. While the present invention is applicable to immersive simulations (e.g., flight simulators certified for commercial pilot training and/or military pilot training), skilled persons will readily recognize and be able to apply its teachings to other types of interactive computer simulations.
In some embodiment, an optional external input/output (I/O) module 1162 and/or an optional internal input/output (I/O) module 1164 may be provided with the instrument module 1160. Skilled people will understand that any of the instrument modules 1160, 1260 and/or 1360 may be provided with one or both of the I/O modules such as the ones depicted for the computer system 1000. The external input/output (I/O) module 1162 of the instrument module 1160, 1260 and/or 1360 may connect one or more external tangible instruments (not shown) therethrough. The external I/O module 1162 may be required, for instance, for interfacing the interactive computer simulation system 1000 with one or more tangible instrument identical to an Original Equipment Manufacturer (OEM) part that cannot be integrated into the computer system 1100 (e.g., a tangible instrument exactly as the one that would be found in the actual system subject of the interactive simulation). The internal input/output (I/O) module 1164 of the instrument module 1160 may connect one or more tangible instruments integrated with the instrument module 1160. The I/O 1162 may comprise necessary interface(s) to exchange data, set data or get data from such integrated tangible instruments. The internal I/O module 1164 may be required, for instance, for interfacing the interactive computer simulation system 1100 with one or more integrated tangible instrument identical to an Original Equipment Manufacturer (OEM) part (e.g., a tangible instrument exactly as the one that would be found in the actual system subject of the interactive simulation). The I/O 1164 may comprise necessary interface(s) to exchange data, set data or get data from such integrated tangible instruments.
In some embodiments, a simulation plan may further be loaded (not shown) from the storage system 1500 in relation the interaction computer simulation that involves the virtual simulated element. The simulation plan may comprise a training plan, a lesson plan or a scenario-based plan (e.g., with specific or dynamic objectives to be reached). The simulation plan may also be used alternatively or additionally to set the period of time covering simulated events from the interactive computer simulation related to the selected virtual subsystem.
The interactive computer simulation system 1000 is typically used to train personnel for complex and /or risky operations. Each interactive computer simulation provides a virtual environment and various tangible instruments (or controls) to allow enactment of different scenarios for the purpose of training one or more users (or trainees), using one or more of the virtual simulated elements, in the operation and/or understanding of the corresponding one or more actual systems. In some situations, real-life training is simply not possible because the target scenario cannot be enacted safely in the real-life (e.g., military mission, rescue mission, medical treatment or operation, etc.). In other situations, it is impractical and/or too costly to enact the training scenario in real-life. The interactive computer simulation system 1000 alleviates the risks and allows for repeated training. The interactive computer simulation system 1000 also limits the overall costs of training when compared to real-life training. Evaluating the performance of the trainee, while it is sometimes only useful, may be critically important (e.g., evaluating preparedness before a mission, certifying competences for license purposes, etc.).
Typically, an evaluation of a trainee in the context of the interactive computer simulation system 1000 consists of an assessment by an instructor based on an interpretation of collected information (e.g., stored dynamic data associated with different events) as well as on visual subjective observations performed by the instructor during the simulation. While it is agreed that a certain level of subjectivity is inherent to most if not all evaluations, there is a perceived risk that the competences of the trainees may not be properly and systematically assessed. For instance, two different instructors may make different visual observations and interpret the same collected information differently. Similarly, quality and/or completeness of the collected data may not sufficient to properly assess performance.
For instance, different interactive computer simulation stations 1100 may comprise slightly different versions of the tangible instrument module 1160 for a single virtual element, leading to differences in the collected dynamic data (e.g., different avionics components in two replicated cockpit of different aircraft simulators for the same real aircraft). Furthermore, some data from dynamic subsystems necessary for the purpose of evaluation of may not be collected at all (e.g., because the data is not exposed to the rest of the virtual environment). For instances, data collected for an aircraft yoke may comprise simulated hydraulic pressure levels in different affected subsystems without comprising the angular position of the actual hardware yoke in the replicated cockpit, or vice-versa. Synchronization of the dynamic data may also create discrepancies in the quality of the resulting evaluation. Typically, the simulation of each of the systems and subsystems requires clock signals (or time steps) for the purpose of synchronization. While a subsystem typically keeps a single time step throughout a given interactive computer simulation, the time step for different subsystems may be different. Conversely, for data collection efficiency purposes, the time at which the dynamic data is collected is not typically constant throughout the simulation and may not either be the same as the initially defined time steps. This discrepancy leads to different integration steps, which, for dynamic systems and subsystems, may induce states divergence. For non-dynamic systems, the difference in time steps induces time delays that might have critical impact on the states being recreated. As another example, some simulators will fully virtualize the tangible instrument 1160 output inside the interactive simulation station 1100 and collect the dynamic data in the form of digital value accordingly (i.e., store a vector of flight-related instructions instead of storing a vector of angular positions for the aircraft yoke). The virtualization made of any given instrument is dependent on technologies available at the time of the development of the virtual element and, when a real instrument is integrated in a replicated environment, is also dependent on the technologies used by the manufacturer of the instrument. The resulting collected data may therefore present disparities considering the manner in which the virtualization has been made.

A method is generally conceived to be a self-consistent sequence of steps leading to a desired result. These steps require physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic/electromagnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It is convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, parameters, items, elements, objects, symbols, characters, terms, numbers, or the like. It should be noted, however, that all of these terms and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. The description of the present invention has been presented for purposes of illustration but is not intended to be exhaustive or limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen to explain the principles of the invention and its practical applications and to enable others of ordinary skill in the art to understand the invention in order to implement various embodiments with various modifications as might be suited to other contemplated uses.
