Typical DS usage

_ Domains HMI Definition, design and validation Performance definition Performance pre-tuning Functional validation Functional safety Life cycle Drivers studies (Communication) _ Type of Immersive Simulation : « Vue Expert » : Professional Drivers (1 to 5) « Vue Clients lambda » : Common Drivers (15 to … 250)

Dif f erent DS

_ Different type of DS with different levels of immersion Motion : Static / Vibration / Dynamic / High dynamic Visual : FOV / Pixel resolution / 2D vs 3D Tools : Head tracking / Eyes tracking / physiological sensors Records : Data / video
