Camera-Based Vehicle Zone Detection for Phone Usage Control

The patent introduces a camera as an intermediary device to detect the location of communication devices and occupants in the vehicle. The camera captures images that are processed to determine whether a device is in the driver or passenger zone, providing spatial information that RF detection alone cannot provide. This intermediary visual detection system resolves the ambiguity of zone differentiation.

The patent replaces or supplements the RF signal-based detection system with a camera-based visual detection system. Instead of relying solely on electromagnetic RF signal analysis, the system uses optical imaging to detect device location and occupant presence, providing more accurate spatial information for zone differentiation.

The patent segments the vehicle interior into distinct driver and passenger zones using image processing. The system divides the captured image into multiple regions corresponding to different seating positions, allowing independent phone usage policies for each zone. This segmentation enables the system to restrict driver phone usage while allowing passenger phone usage without requiring completely separate detection systems.

The patent makes the single camera-based detection system multi-functional by enabling it to perform both driver zone monitoring and passenger zone monitoring simultaneously. The same camera and processing system adapts to provide different detection outcomes based on which zone contains a communication device, achieving zone-specific policies through a universal detection platform.
