Light Armored Vehicle Simulator Demonstration

Arriving on the floor to setup for a trade show, Ivan finds himself in a stressful situation: Only 4 hours for setting up a demo of a collaborative Light Armored Vehicle (LAV) simulator. The new partner, ADVENTUREtech, just introduced a display system that needs to become part of the simulation.

The demo includes 4 different user stations: 

  • LAV Driver in an ergonomic seat inside a 3 channel CAVE display 
  • Gunner using game controller with a single monitor 
  • Commander using the Oculus VR head gear
  • Observers on a monitor to display what the Commander sees

"VT MAK's product suite transformed a booth with a display system into a fully-functional, team-oriented training demonstration."

The MAK Advantage:

MAK used its Light Armored Vehicle (LAV) simulator built on VR-Forces and VR-Vantage to set up this system.

VR-Vantage IG is used to provide trainees with high-detail role-specific visual scenes. VR-Vantage's multi-channel distributed rendering architecture makes it easy to configure a continuous scene across a CAVE display. The CAVE is a form of display that displays scenes onto three to six sides of a cube. CAVEs provide a wide viewing angle that makes an immersive environment for the Driver without the expense of edge blended dome displays. This display is a good match with the ergonomically positioned driver controls that make driving natural and leave the operator's attention on the mission.

The Gunner's view is presented on a single monitor and operated with a commercial game controller. The gunner IG supports daylight visual and night vision scenes, toggled by a switch on the game controller. This lower fidelity interface is appropriate if the gunner’s tasks focus on targeting decisions and communicating with the commander, but could be implemented with higher fidelity interfaces if shooting skills were important. 

The Commander is using the Oculus VR headgear to present a fully immersive display that is reactive to his head position and movements. A video monitor is used to show observers what the Commander is seeing.

The VR-Forces simulation engine is hosting the light armored vehicle ownship simulation. It uses CM Lab’s Vortex physics engine to model the vehicle and gun dynamics. Because it’s based on VR-Forces simulation framework, it can coordinate user inputs from each of the operators, provide terrain access to the Vortex models, and handle the weapons effects, sensors, and damage models for the vehicle. 

The terrain used is Simthetiq’s SUROBI VTE, a terrain database hand built from source data from the Surobi valley in Afghanistan. This database provides high performing models with close-up detail of a typical Afghan village. 

The virtual simulator is connected through the network, using VR-Link, to two other simulations. VR-Forces CGF, which simulates neutral, friendly and opposing force entities. VR-Forces enables instructors to pre-plan training scenarios where non-player AI move and interact based on mission plans, reactive tasks, and triggers based on the actions of other entities in the simulation. Instructors and role players can interact at several levels: they can give squad leaders tasks and have the members of the squad follow those instructions, they can command individual entities, or take first person control of vehicles and human characters. 

Di-Guy Scenario can add additional human characters to the simulation that model the patterns of life in the village and react to the actions of the LAV. 

VR-Forces, VR-Vantage, and DI-Guy Lifeform Server include MAK’s networking technology. VR-Link’s protocol independent API allows all three applications to communicate through industry standard High Level Architecture (HLA) and the Distributed Interactive Simulation (DIS) protocols, including HLA 1.3, HLA 1516, HLA Evolved, DIS, and DIS 7. The MAK Data Logger records and plays back all the network simulation traffic for after action review and analysis. The MAK RTI (runtime infrastructure) is available when connecting to HLA federations using any of these SISO standard protocols: HLA 1.3, HLA 1516, and HLA Evolved.
