Eye Tracking Device for Dynamic Vehicle Display Prominence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-vehicle user interfaces and instrument clusters require significant driver attention and can be distracting, leading to less safe driving conditions due to their complexity and need for manual interaction.
Innovation Solution
An eye tracking device is integrated into the vehicle system to monitor driver gaze location and adjust the prominence of indicators on the display based on sensor data thresholds and gaze frequency, ensuring that critical information is prominently displayed only when the driver is focused on the relevant area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If complex displays with multiple visual outputs are used in vehicle interfaces, then information completeness is improved, but driver distraction increases
Solution Approach 1:
The system dynamically adjusts display prominence based on real-time gaze detection. Indicators transition between prominent and non-prominent states depending on whether the driver is looking at them, creating a dynamic interface that adapts to driver attention patterns rather than using static complex displays
Solution Approach 2:
Different display elements receive different levels of prominence based on their current relevance and driver gaze. Instead of uniformly displaying all information with equal visibility, the system applies local quality variations where only gaze-relevant indicators are prominently displayed while others are minimized or hidden
2Loss of information
If multiple indicators are displayed simultaneously, then information availability is improved, but visual clutter increases
Solution Approach 1:
The display system dynamically reconfigures itself based on driver gaze patterns. Indicators that are currently being viewed by the driver are maintained in prominent positions, while other indicators are temporarily reduced or moved, creating a dynamically simplified display that preserves information availability without constant visual clutter
Solution Approach 2:
The display is segmented into multiple prominence levels (prominent, non-prominent, hidden) based on driver gaze patterns. This segmentation allows the system to present information in organized layers, showing only relevant indicators prominently while maintaining access to other information at lower prominence levels
3Ease of operation
If gaze-based prominence adjustment is implemented, then driver focus is improved, but system complexity increases
Solution Approach 1:
An eye tracking device serves as an intermediary between the driver and the display system. This intermediary captures gaze data and translates it into prominence adjustment commands, allowing the system to respond to driver attention without requiring complex direct integration between multiple display components and control systems
