Gaze-Based Vehicle Warning Display and Function Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack effective methods to utilize driver gaze direction for dynamic control of in-vehicle messaging and vehicle functions, particularly in enhancing warning visibility and activating relevant features based on gaze direction and duration.
Innovation Solution
A system utilizing sensors and an electronic processor to determine driver gaze direction, activating normal or augmented display modes for warnings and enabling vehicle functions based on gaze zones and durations, including features like see-through trailer and hood functions, and gaze-based activation/de-activation of vehicle features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If warning indicators are displayed with augmented display mode (increased size, brightness, color change) when driver gaze is away from the warning, then warning visibility is improved, but driver distraction may increase due to more prominent displays
Solution Approach 1:
The warning indicator dynamically changes its display characteristics (size, brightness, color) based on the driver's gaze direction detected by sensors. When the driver is not looking at the warning, it displays in augmented mode with enhanced visibility. When the driver looks at it, it switches to normal mode, reducing distraction while maintaining information delivery.
Solution Approach 2:
The system changes multiple display parameters (size, brightness, color) of the warning indicator based on gaze detection. These parameter changes are triggered when the driver's gaze is detected to be away from the warning indicator, optimizing visibility without causing distraction when the driver is already attentive to the warning.
2Loss of information
If the system continuously monitors driver gaze direction and dynamically adjusts display modes, then warning visibility and function activation are optimized, but device complexity increases due to additional sensors and processing requirements
Solution Approach 1:
The electronic processor performs multiple functions: it processes gaze direction data from sensors, determines gaze zones, controls warning indicator display modes, and activates vehicle functions based on gaze duration. This multi-functionality reduces the need for separate dedicated components for each task.
Solution Approach 2:
The system uses the driver's own gaze behavior as the control signal for adjusting display and activating functions. The driver's natural eye movements serve as the input mechanism, eliminating the need for complex manual controls or additional user interface elements.
3Loss of information
If augmented display mode is activated when gaze direction differs from warning indicator location, then warning attention is improved, but energy consumption increases due to higher brightness and additional display elements
Solution Approach 1:
The system periodically monitors the driver's gaze direction and dynamically switches between normal and augmented display modes. The augmented mode with higher energy consumption is activated only periodically when the driver's gaze is detected to be away from the warning, rather than continuously, thus reducing overall energy usage while maintaining attention when needed.
