SIMULATIONS AND VR USE IN THE MILITARY
EARLY MILITARY SIMULATIONS
• ABAX (SAND TABLE) USED FOR PRACTICING WRITING, DOING CALCULATIONS, PLAYING GAMES, PLANNING MILITARY ATTACKS, ETC.
• ("The word abax, or abacus, is used both for the reckoning-board with its counters and the play-board with its pieces, ...")
• The Still used today
THE FIRST WARGAME: “WAR CHESS”
• Prussia in 1780 by Johann Christian Ludwig Hellwig. Hellwig's wargame was the first true wargame because it attempted to be realistic enough to teach useful lessons in military strategy to future army officers. Hellwig was a college professor and many of his students were aristocrats destined for military service. But Hellwig also wanted to sell his wargame commercially as a recreational item. Hellwig chose to base his game on chess so as to make it attractive and accessible to chess players.[18] Hellwig published a second edition of his rulebook in 1803.
KRIEGSPEIL, 1824
• In 1824, a Prussian army officer named Georg Heinrich Rudolf Johann von Reisswitz presented to the Prussian General Staff a highly realistic wargame that he and his father had developed over the years. Instead of a chess-like grid, this game was played on accurate paper maps of the kind the Prussian army used. This allowed the game to model terrain naturally and simulate battles in real locations. The pieces could be moved across the map in a free-form manner, subject to terrain obstacles. The pieces, each of which represented some kind of army unit (an infantry battalion, a cavalry squadron, etc.), were little rectangular blocks made of lead. The pieces were painted either red or blue to indicate the faction it belonged to.
KRIEGSPEIL, 1824• The umpire uses dice to determine how much damage that attacking units inflict
upon the enemy. The dice designed by Reisswitz are of unique design, with each face displaying a multitude of numbers and symbols that denoted different damage scores, measured in points, for different situations. There are five dice:
• Die I is used to determine ranged damage inflicted by line infantry and skirmishers fighting in the open, hand-to-hand combat results when both sides were even, and whether a howitzer attack sets a village on fire.
• Die II is used to determine ranged damage by skirmishers firing from cover, and hand-to-hand combat results when the odds are 3:2.
• Die III is used to determine damage inflicted by artillery under good conditions.
• Die IV is to determine hand-to-hand combat results when the odds are 3:1.
• Die V is used to determine damage inflicted by artillery under bad conditions, and hand-to-hand combat results when the odds are 4:1.
MINIATURES WARGAMES
• Popularized in England by H. G. Wells
• Little Wars (1913). This is widely remembered as the first rulebook for miniature wargaming (for terrestrial armies, at least). Little Wars had very simple rules to make it fun and accessible to anyone.
• Jack Scruby brings Military miniatures to the US in the 1950s
• The Soldier factory opens in Cambria in 1973
• Gary Gygax was another early American miniatures player who helped develop a medieval wargame called Chainmail in 1971 and that famously evolved into Dungeons & Dragons in 1974
MILITARY SIMULATORS
• 1929 analog flight simulator
• 1942 the “Blue Box” widely used during WWII to train pilots
The Link Trainer “The Blue Box”
SIMNET
• Interesting networked simulation for semi real time planning
• First virtual batlefield
• William Gibson Didn't Invent Cyberspace, Air Force Captain Jack Thorpe Did.
• Wired 04.01.97
• Lead to Arpanet, the precursor to the Internet 1983
WHAT TO MODEL?• How realistic does the virtual model have to be?• Thorpe realized that just a few bits of data needed to be kept on each
entity• "... advances which are seen on the horizon are not simple improvements in
teaching techniques or higher fidelity simulators, but rather bold concepts which tightly align training systems with real combat readiness and make them indistinguishable.“
• SIMNET and Insider’s perspective
• "Group interactions are the most complicated combat operations," says the tall, soft-spoken Thorpe. "They also tend to be the ones in which the costs of screwing up are the highest. Yet because it is so difficult and expensive to organize groups, pilots get very little training in collective skills. They have to learn these skills on the job, during combat, which makes casualties disproportionately high during the first few missions.“
• Wired 04.01.97
• Lead to Arpanet, the precursor to the Internet 1983
MILITARY SIMULATION AS REALITY
• Set at an unspecified date in Earth's future, the novel presents an imperiled humankind after two conflicts with the Formics, an insectoid alien species they dub the "buggers". In preparation for an anticipated third invasion, children, including the novel's protagonist, Andrew "Ender" Wiggin, are trained from a very young age by putting them through increasingly difficult games, including some in zero gravity, where Ender's tactical genius is revealed.

SIMULATION INDISTINGUISHABLE FROM ACTUAL WAR
• UAV air crews
• https://youtu.be/_w5NGKt71k4
• Training, modeling, simulation
• How close to something like Ender’s game are we?
• Certainly with some Air and sea operations
• But ground troops?
MARINE DOOM
• 1996 modification of the first-person shooterDoom II for the United States Marine Corps, which was later made available for download to the public.
GROWING MARKET

SAFETY• Oculus safety video
https://youtu.be/NB3Fqmwx_E8• Eyesight
• "There are a variety of potential issues," said University of California, Berkeley optometry Professor Martin Banks, who studies visual perception in virtual environments. "One is how we affect the growth of the eye, which can lead to myopia or nearsightedness."
• "In a virtual environment, the way we look and interact is changed because we may be projecting onto the eyes something that looks far away, but in reality, it's only a few centimeters from the eye," said Walter Greenleaf, a behavioral neuroscientist who has studied VR in medical settings for over 30 years. Science calls that the "vergence-accommodation conflict" and isn't quite sure how serious it might be. "We're tricking the brain," said Greenleaf, who works with Stanford University's Virtual Human Interaction Lab, "and we don't know the long-term effect of this.“

SIMULATIONS AND VR USE IN INDUSTRY
VR AND RENEWABLE ENERGY
• Letting Shareholders virtually tour sites
• Augmented reality Turbine lab• Fife College Immersive Hybrid Reality lab opened in Scotland in 2017 and introduced a virtual reality
system that teaches students to troubleshoot on the nacelle of a seven-megawatt offshore wind turbine by simply wearing a specialized goggles.
• Because the use of VR and AR are more cost efficient and safer as compared to actually sending trainees on site, the renewable energy sector is now joining the ranks of oil and gas, aerospace, nuclear, and construction industries as primary users of the VR technology for training.

VR AND NUCLEAR ENERGY
• Visualize reactors in action
• Training in otherwise restricted or secure sites
• Virtual reality is becoming more common in gaming, but industry is also jumping on the VR bandwagon. GE has been experimenting with using VR for applications as varied as factory design and medical scans. At GE Healthcare’s Global Center of Excellence in Medical Imaging Software in Buc, France, engineers used detailed 3D information from CT and MRI body scans to build a virtual experience that enables doctors to “enter” a specific part of the body and closely examine it for anomalies like polyps, tumors and lesions.
