VR simulation for…
…training and entertainment
Important note
‐ Some concepts already explained in other VR lectures‐ Here with different applications and examples
Today’s focus
Contents
EntertainmentMovie based VRVideo‐gamesSportsSpecialized
Semi immersive environment: Large Projection Screen
With 3D animations and sound
‐Gesture recognition: grasp and throw balls
‐ Physics simulation: parabolic trajectory of balls and rigid‐body dynamics
EducationSport trainingPétanque
Golf simulation
Similar to pétanque
EducationSport trainingFootball
Football
Faculty of sport science of Marseille, FR
Full immersive environment: four projection screens (of 3x4 m)
Virtual human development with motion capture of professional soccer player from Olympic de Marseille
EducationSport trainingParachute
Parachute jumping

Exploring, To avoid pain Exploring far places
Because it is too far
Google earth can help
EntertainmentExploring
EntertainmentExploring
Exploring unreachable places
Because it is really too far!
Should be presented in more details in the laboratory CAVE
EntertainmentTo avoid pain
Patient's attention is taken up
Important note:VR tools not applied for
reeducation but for entertainment here
Medical staff performing tasks that generates fear and/or pain
For kids
Can we still consider that as «entertainment»?
VR games for young burn patients
VR can help young patients going to the dentist
Young patient diverts his attention away from a painful medical treatment

EntertainmentTo avoid pain
Patient's attention is taken up
Intensive pain
Adult patient too
Water‐friendly VR helmet during wound care in the hydrotub (HIT lab)
Lonnie 39‐year‐old, who suffered third‐degree burns, soaks in a tub of water and wears a RV headset that shows him pictures of winter scenes while his bandages are changed.

History
Student pilots learned how to manoeuvre airplanes by:
‐manipulating controls in specially built airplane cockpits
‐removed from airplanes themselves
‐mounted on movable platforms that tilted and rolled based on pilot's actions on controls
Can be considered as the first main step towards RV
US navy VR Flight Simulator
TrainingFlight simulators
Development
Very significant contributions to development of VR
Much of technology needed for VR developed for US Army

TrainingFlight simulators
Simultaneous aspects
Many aspects to take into account simultaneously
Graphics includes
‐Friend /foe identification
‐Targeting information
‐Threat information, e.g. based missile sites
‐Optimal flight path information
‐Large angle view => multi‐screens
Multi‐screens flights simulators
Magic Edge
TrainingFlight simulators
Entertainment example
Magic Edge
Fighter pilots battle each other
Fully rendered virtual landscape
TrainingFlight simulators
Fighter pilot
Operating under extremely high stress levels
Both cognitive and physical
Has to assimilate and process masses of data
TrainingFlight simulators
Update rates
Very fast tracking and redisplay
Preferably 60 frames per second (fps)
At the very least 25 fps
/!\ relative notion of real‐time
=> anyway, fps has to beconstant

TrainingFlight simulators
Short lag times
=> no noticeable delay between movement and production of correct visuals
Secondary visual cues
=> shadows and textures
=> motion and force feedback
Battlefield Highly Immersive Environment within the US Army Aviation and Missile Research Development
TrainingFlight simulators
Costs
Professional flight simulators remains very expensive (tens of millions)
For VR, we must achieve similar fidelity at a tiny fraction of the cost
Cost issues discussed later, see CAVE example
Relationship between level of experience and simulator fidelity
Virtual take off simulator
SGI simulator
TrainingFlight simulators
What to simulate
Real cockpits with their instruments, joysticks, levers, switches, buttons, etc.
Each instrument possess individual mechanical characteristics
Pilots constrained to floor‐mounted chairs, and during take‐off and landing scenarios, restrained by seat belts
“ridiculous” to build all instruments and chairs in virtual world
Helicopter simulator
High‐resolution images for the full‐mission simulators
French & German army
CEV’s Tiger helicopter simulators

Ergonomics, Security, Interior designs, Learning how to drive, Heavy vehicles
TrainingLight vehiclesCar simulation
Ergonomics
New car: size 1:1 car mock‐up, probably the most expensive aspect
Designing driver’s front board => tricky optical problem
Simulating in real‐time complex light effectpossible with highfidelity
/!\ Remains valid only for few materials

TrainingLight vehiclesCar simulation
Security
‐ Improving vehicle safety
‐ 3D collision simulations are possible
‐ Still difficult to simulate
‐Almost impossible to guarantee
