Abstract

L'invention concerne des systèmes et des procédés se rapportant à des systèmes de réalité étendue (XR), tels qu'un système de réalité virtuelle (VR), un système de réalité mixte (MR) ou un système de réalité augmentée (AR). Des changements de scène moins gênants ou imperceptibles peuvent être effectués lorsque l'utilisateur expérimente une indifférence aux changements. Un capteur physiologique peut être utilisé pour mesurer un état physiologique de l'utilisateur. Un sous-système de détection d'indifférence aux changements peut déterminer que l'utilisateur expérimente une indifférence aux changements sur la base d'une valeur de charge cognitive calculée dépassant une valeur seuil d'indifférence aux changements.
