Ty p i c a l D S u s a g e
Different DS
_ Domains
HMI Definition, design and validation
Performance definition _ Different type of DS with different levels of immersion
Performance pre-tuning Motion : Static / Vibration / Dynamic / High dynamic
Functional validation Visual : FOV / Pixel resolution / 2D vs 3D
Functional safety Tools : Head tracking / Eyes tracking / physiological sensors
Life cycle Records : Data / video
Drivers studies
(Communication)
_ Type of Immersive Simulation :
« Vue Expert » : Professional Drivers (1 to 5)
« Vue Clients lambda » : Common Drivers (15 to … 250)
