Display Privacy Control Using Predicted Viewing Direction

The patent applies dynamics by transitioning from static viewing protection filters to a dynamic system that continuously tracks eye positions and adjusts protection in real-time. The system uses eye tracking cameras to monitor viewer positions and dynamically modifies display content or applies virtual viewing protection that adapts to changing viewing directions, thereby maintaining privacy protection while enabling flexible display positioning throughout the vehicle interior.

The system changes parameters by adjusting viewing protection based on detected eye positions and viewing directions. Rather than using fixed angular protection, the system dynamically modifies protection parameters (such as obscuring specific screen regions or adjusting transparency) based on real-time detection of unauthorized viewing attempts, enabling both reliable privacy protection and adaptable display positioning.

The patent applies local quality by implementing selective viewing protection that targets specific regions of the display based on detected eye positions. Rather than uniformly restricting viewing across the entire screen, the system applies protection only to regions being viewed by unauthorized persons, while maintaining full accessibility for authorized users. This enables differentiated access where authorized persons experience no restrictions while unauthorized viewing is blocked.

The system uses feedback by continuously monitoring eye positions through cameras and using this information to dynamically adjust viewing protection. The detected eye positions provide feedback that triggers selective obscuring or protection measures, creating a closed-loop system that adapts to current viewing conditions. This ensures that authorized persons maintain unrestricted access while unauthorized viewing attempts are automatically detected and blocked.

The patent replaces the mechanical system of physical viewing protection films with a software-based virtual viewing protection system. Instead of fitting physical filters that obscure display content, the system uses eye tracking technology and software algorithms to dynamically control what content is displayed or how it is presented. This substitution eliminates the need for physical film installation while providing superior, adaptable privacy protection that enhances rather than diminishes perceived value.

The system transitions from static physical films to dynamic virtual protection that adapts in real-time. The dynamic nature of the software-based solution, which continuously adjusts protection based on detected viewing directions and positions, provides a more sophisticated and valuable experience compared to fixed physical films, thereby improving user perception of value while maintaining effective privacy protection.
