Blurred Screen Interface Reduces Driver Eye Adaptation Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technologies fail to effectively reduce the time duration for driver-eye adaptation when switching focus from events in front of a vehicle to a screen in the driver's compartment, leading to increased visual distraction and risk of accidents, especially at higher speeds.
Innovation Solution
A method that processes and displays a recorded image sequence with reduced sharpness impression by adjusting resolution, contrast range, and brightness steps, and optionally smoothing the image, to minimize eye adaptation time when switching between the vehicle environment and the screen, using a camera and processing module to generate a background image with reduced sharpness for the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the screen displays detailed information, then the driver receives comprehensive information, but the driver becomes more distracted from the driving task
Solution Approach 1:
Instead of displaying processed or interpreted information about the road environment, the system displays a direct visual copy (live feed) of the actual road scene. This copying approach provides comprehensive environmental information while maintaining the driver's situational awareness, as the blurred feed still accurately represents the real-world environment without adding distracting graphical elements.
Solution Approach 2:
The blur effect is applied selectively to the background live feed while keeping the foreground menu elements sharp and clear. This local quality differentiation ensures that information remains accessible while the background provides contextual awareness without causing distraction.
2Measurement precision
If a live image with high sharpness is displayed on the screen, then the driver can see clear details, but the driver's eyes require more time to adapt when switching to events in front of the vehicle
Solution Approach 1:
Instead of displaying a sharp clear image and accepting the adaptation penalty, the system inverts the approach by deliberately displaying a blurred image. This inversion of the expected quality parameter reduces the visual discrepancy between screen and road, thereby minimizing eye adaptation time when switching between the two views.

AI summary
According to the disclosure, a method is made available to reduce a time duration for an adaption of eyes of a driver of a motor vehicle when changing from events occurring in front of the motor vehicle to a screen arranged in a driver's compartment of the motor vehicle. In particular, the method according to the disclosure also makes a reduction available in the time period for the adaption of the eyes of the driver in the opposite direction.
