Vehicle Cabin Interface Control by Camera-Based Seat Detection

The patent replaces the mechanical/acoustic sensor-based position detection system with an optical imaging system. Instead of using multiple ultrasonic sensors to detect mobile terminal positions, the invention uses a single camera to capture images of the vehicle interior and identifies user positions by detecting facial features in the captured images. This substitution of mechanical/acoustic detection with optical detection resolves the contradiction by achieving position detection accuracy without requiring multiple sensors.

This substitution of mechanical/acoustic detection with optical detection resolves the contradiction by achieving position detection accuracy without requiring multiple sensors, thereby simplifying manufacturing and retrofitting processes.

The patent implements a system where the vehicle-mounted device automatically detects user seating positions using facial recognition technology and autonomously provides differentiated screen interfaces based on the detected positions. The system does not require manual user input or complex configuration - it self-identifies user locations by analyzing facial images captured by the camera and automatically adjusts the interfaces presented to each user. This self-service approach improves user convenience while avoiding the cost and complexity of manual interface configuration systems.
