Vehicle Information Display Selection for Privacy-Safe Projection

The patent applies local quality by projecting information onto specific local areas such as the user's hand or body parts. The projection location is dynamically selected based on the type of information - personal information is projected onto body parts that can be concealed (hand, arm, leg), while non-personal information can be displayed on external surfaces. This creates different display qualities for different information types, allowing privacy protection while maintaining usability.

The patent applies dynamics by making the intervehicular distance adjustable rather than fixed. The system dynamically adjusts the distance based on operational context - maintaining larger distances during autonomous operation for safety, but reducing distances when manual control is engaged or during parking operations. This allows the system to optimize both safety and space utilization at different times.

The patent applies self-service by enabling gesture-based control that allows users to naturally interact with the vehicle system using intuitive hand movements. The system automatically recognizes gestures and executes corresponding commands without requiring users to learn complex operation procedures. This maintains control precision through accurate gesture recognition while dramatically improving ease of use.
