Driver Attention Retargeting Through Adaptive Display Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent glancing of drivers at various visual display outputs in vehicles leads to safety issues due to distraction from critical driving tasks.
Innovation Solution
A method and system to retarget a driver's visual attention by determining target regions on the display output to increase or decrease attention through adjustments in visual content, using sensors and saliency maps to identify and modify display content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual display outputs provide more information to the driver, then the driving experience and information communication are improved, but the driver's attention is diverted from critical driving tasks causing safety issues
Solution Approach 1:
The patent applies local quality by making different regions of the display have different visual properties. Specifically, it identifies a driver attention region (where the driver is currently looking) and a target region (where attention should be directed) on the display, then modifies visual properties (such as brightness, contrast, or content) specifically within the target region to attract the driver's attention without altering the entire display, thus maintaining safety while improving information communication.
2Reliability
If the visual display output is modified to draw attention to particular content, then driver attention is retargeted to critical information, but the display complexity and processing requirements increase
Solution Approach 1:
The patent applies segmentation by dividing the display into distinct functional regions: a driver attention region (detected via sensor data indicating where the driver is looking) and a target region (where critical information should be presented). By segmenting the display this way, the system can apply attention-drawing modifications only to the target region rather than processing the entire display, reducing computational complexity while maintaining effective attention retargeting.
Solution Approach 2:
The patent employs feedback by using sensor data to detect the driver's current attention region and using this information to dynamically adjust the display content in the target region. The system continuously monitors driver gaze position and adjusts the visual display accordingly, creating a closed-loop feedback system that retargets attention without requiring complex pre-planning of all possible display scenarios.

AI summary
A visual display output retargeting system and method, and visual display output control system having the visual display output retargeting system and implementing the method. The method includes: determining target driver attention data for a vehicle operator, wherein the target driver attention data indicates one or more target regions of a visual display output to be displayed to the vehicle operator; and determining visual display output data representing the visual display output as adjusted based on the target driver attention data for the vehicle operator through making adjustments to content of one or more retargeted regions of the visual display output so as to increase or decrease a likelihood of drawing the visual attention of the vehicle operator towards said retargeted region(s).
