Abstract: A method for providing an interactive virtual communication environment within a vehicle uses real-time sensor data. The method acquires data from one or more vehicle sensors, which is then processed to derive occupant-specific data. Using this occupant data, the method configures a virtual environment that is displayed on the vehicle's display device. Within the virtual environment, an avatar representing the vehicle's occupant is generated based on the sensor data and associated occupant information. The avatar serves as an indicator of the occupant's presence and identity within the virtual environment, providing a more accurate and real-time indication of the occupant's availability for interaction, thereby reducing hardware complexity of the communication platform inside the vehicle.
