Driver HUD Information Gating by Real-Time Attention Score
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for displaying information to drivers in vehicles do not effectively balance the amount and type of information shown with the driver's attentional state, leading to potential distractions and compromised safety, as they lack dynamic control based on real-time conditions such as traffic, vehicle status, and driver physiological and psychological states.
Innovation Solution
A device that calculates an attentional score using various sensors and information sources to determine whether to display information based on threshold values associated with different classes of information, ensuring that only relevant and non-distracting content is shown to the driver, particularly using a head-up display or integrated vehicle screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information is displayed in the driver's field of vision, then driver alertness can be increased, but driver distraction may occur reducing safety
Solution Approach 1:
The system dynamically adjusts the display of information based on the driver's real-time attentional state. Sensors continuously monitor physiological indicators (eye movements, pupil dilation, blink rate, heart rate variability) and the system adapts the information display accordingly, showing more information when attention is high and reducing information when attention drops, thereby preventing distraction while maintaining alertness
Solution Approach 2:
The system implements a closed-loop feedback mechanism where sensors detect the driver's attentional state, the processor analyzes this data to determine attention level, and the display system adjusts information presentation based on this feedback. This continuous monitoring and adjustment cycle ensures that information display remains optimized for both safety and alertness without causing distraction
2Adaptability or versatility
If predetermined display configurations are used, then information can be displayed to the driver, but dynamic control based on real-time conditions is not possible
Solution Approach 1:
The system integrates multiple functions into a single platform: sensors for physiological monitoring, processors for attentional state analysis, and display systems for information presentation. This multi-functional integration allows the system to adapt to various driving conditions and information types without requiring separate dedicated systems for each function, managing complexity through consolidation
Solution Approach 2:
The system changes operational parameters (information display content, quantity, and timing) based on detected physiological parameters (eye movements, pupil dilation, blink rate, heart rate variability). By linking display parameters to physiological parameters in real-time, the system achieves dynamic adaptability without requiring complex rule-based configurations for each scenario
Data Source
AI summary
A device to control the display of information in a field of vision of a driver of a vehicle. A memory to store a table associating different classes of display with respective threshold values of an attention score representative of a level of attention of the driver. One or more processors configured to: collect information to be displayed in the field of vision of the driver, each piece of information belonging to a display class, collect attention information relating to the level of attention of the driver, and calculate an attention score representative of a level of attention of the driver from the collected attention information. For each piece of information: the processor is configured to compare the calculated attention score to the threshold value associated with the display class to which the information belongs, and to determine whether to display the piece of information depending on the comparison result.
