In-Vehicle Display Layout Control Using Driver Gaze Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle display systems fix information categories in predefined regions, requiring users to adapt to the information structure for improved user experience, which can be cumbersome and distracting while driving.
Innovation Solution
A control method and apparatus that adjust the information structure on display units in response to a user's line of sight, using a multi-level interface to enlarge or shrink regions based on gaze direction, display notification messages, and adjust brightness and orientation to enhance user experience and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If information categories are fixedly displayed in predefined regions, then the display structure is simple and stable, but users must adapt to the information structure which reduces user experience and increases distraction
Solution Approach 1:
The display system dynamically adjusts the information structure based on the user's line of sight. The controller receives gaze information from the sensor and automatically reconfigures display regions, allowing the display to adapt to user needs without requiring manual operation or user adaptation to fixed layouts
Solution Approach 2:
The display system serves itself by automatically adjusting its own information structure based on detected user gaze patterns. The sensor and controller work autonomously to reconfigure display regions without user intervention, making the system self-adaptive to user viewing behavior
2Adaptability or versatility
If the display system dynamically adjusts information structure based on line of sight, then user experience is improved, but the system complexity increases
Solution Approach 1:
The sensor unit serves multiple functions: it detects user line of sight, determines gaze duration, and provides input for display configuration decisions. This multi-functionality reduces the need for separate specialized components, managing system complexity while achieving adaptive display capabilities
Solution Approach 2:
The system changes display parameters (region positions, sizes, and content allocation) based on detected line of sight parameters. By dynamically adjusting these parameters rather than changing the fundamental display hardware architecture, the system achieves adaptability with controlled complexity

AI summary
The present invention provides a control method for information display, a control apparatus for information display and a vehicle. The method includes adjusting an information structure of display information on a display unit in response to a shift of a user's line of sight on the display unit while driving the vehicle. Therefore, the user does not need to adapt the information structure in a display panel or to perform any manual operation, such that user experience can be improved while ensuring safety.
