Vehicle Display Head Position Sensor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems face challenges in presenting a balanced load of information to drivers without distracting them from the task of driving, as they require manual interaction to access non-constant information, and existing head-tracking systems have limitations in efficiently managing information display based on the driver's head position.
Innovation Solution
A vehicle display arrangement that uses sensors to monitor the driver's head position and automatically initiate dimension changes or relation adjustments of graphical display objects, allowing drivers to access information by changing their head position, thereby maintaining hands on the steering wheel and enhancing intuitive interaction with the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual interaction with display control means is required to access non-constant information, then information access is possible, but driver distraction and operation complexity increase
Solution Approach 1:
The display system automatically detects driver head position using sensors and autonomously adjusts the displayed information without requiring manual interaction. The system serves itself by monitoring driver state and modifying the interface accordingly, eliminating the need for drivers to manually navigate through menus or press buttons to access different information types.
Solution Approach 2:
The patent replaces manual mechanical interaction (buttons, knobs, touch screen gestures) with automatic sensor-based detection of head position. Optical or other sensing systems detect driver orientation and trigger display changes automatically, substituting the mechanical control system with an automated sensing and response system.
2Loss of information
If a great load of information is presented constantly to the driver, then information availability increases, but cognitive overload and safety decrease
Solution Approach 1:
The display system dynamically adjusts the type and amount of information presented based on real-time detection of driver head position and orientation. Instead of a static information load, the system continuously adapts the displayed content to match the driver's current attentional state and informational needs, optimizing information delivery while preventing cognitive overload.
Solution Approach 2:
Different regions or aspects of the display provide different types of information based on the driver's head position. The system applies local quality by tailoring the information content to specific viewing angles or head positions, ensuring that only relevant information is presented at any given moment rather than overwhelming the driver with all possible information simultaneously.
3Ease of operation
If head tracking system modifies display based on head position, then information accessibility improves, but system complexity increases
Solution Approach 1:
The head tracking system serves multiple functions: it detects driver attention state, determines information priority, controls display content selection, and adjusts presentation format. By making the sensor system universal and multi-functional, the patent reduces overall system complexity compared to having separate systems for each function.
Solution Approach 2:
The patent combines the head tracking sensor, processing unit, and display control into an integrated system. Rather than having separate components for head detection, information management, and display control, these functions are merged into a unified system that operates as a cohesive whole, reducing complexity through integration.
