Vehicle Windshield Display Priority Using Multi-Occupant Gaze
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems struggle to effectively manage and prioritize the display of external interest information for multiple occupants in a vehicle, failing to account for individual gaze directions and preferences, leading to potential conflicts and inefficiencies in information presentation.
Innovation Solution
A system that recognizes the gaze of multiple occupants and controls the vehicle display based on gaze information, determining display areas and priorities to minimize overlap and ensure that important information is displayed according to individual preferences and needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If external interest information for multiple occupants is displayed on the vehicle windshield display, then information completeness is improved, but display area overlap occurs
Solution Approach 1:
The system segments the windshield display area into multiple non-overlapping regions, each assigned to a specific occupant based on their gaze direction. This segmentation allows simultaneous display of multiple occupants' interest information without spatial overlap, resolving the contradiction between information completeness and display area conflict.
Solution Approach 2:
The system applies local quality by customizing the display content and position for each specific occupant's gaze direction. Each occupant receives personalized information display in their respective visual field, ensuring that information is presented in the most appropriate location for each user while preventing overlap between different occupants' displays.
2Productivity
If display priority is determined for overlapping areas, then display efficiency is improved, but display flexibility is reduced
Solution Approach 1:
The system implements dynamic priority determination where display priorities are not fixed but adapt in real-time based on multiple factors including occupant roles (driver vs. passenger), gaze duration, and information importance. This dynamic approach maintains display efficiency through automated priority rules while preserving flexibility by adjusting priorities according to changing contextual conditions.
Solution Approach 2:
The system incorporates feedback mechanisms that continuously monitor occupant gaze behavior and adjust display priorities accordingly. By analyzing gaze duration, fixation points, and occupant responses, the system dynamically recalibrates display priorities to optimize both efficiency and adaptability, allowing the display strategy to evolve based on real-time feedback from multiple occupants.

AI summary
A system for controlling a vehicle display based on an occupant's gaze includes: a first occupant gaze recognition unit to recognize a gaze of a first occupant in a vehicle; a second occupant gaze recognition unit to recognize a gaze of a second occupant in the vehicle; an interest information display area crossover confirmation and priority determination unit to determine interest information from the gaze of the first occupant and the gaze of the second occupant, to confirm whether areas for displaying interest information on a windshield are mutually crossover with each other, and to determine a priority for display; and a display control unit to control a display in accordance with the priority for display.
