Vehicle Display View Adjustment for Readable Gaze-Tracked Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display devices, particularly head-up displays, require drivers to frequently change their gaze direction, leading to reduced readability and increased risk of motion sickness due to distorted content appearance and distraction from the road.
Innovation Solution
A method and system for controlling display devices that apply both positional and perspective adjustments to the displayed content based on drive situation conditions, such as driver gaze and vehicle direction, ensuring the content remains readable and undistorted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the displayed content is moved to follow the driver's gaze direction, then the content remains in the driver's field of view, but the content appears distorted which reduces readability
Solution Approach 1:
The display system dynamically adjusts the position of displayed content based on detected driver gaze direction. The control unit receives gaze information from the gaze detection unit and automatically repositions content on the display device to maintain it within the driver's field of view, making the display adaptive to the driver's natural head and eye movements
Solution Approach 2:
The system implements a feedback loop where the gaze detection unit continuously monitors the driver's gaze direction, and this information is fed back to the control unit which adjusts the content position accordingly. This closed-loop control ensures the content remains optimally positioned without requiring manual intervention or fixed positioning
2Adaptability or versatility
If the driver looks in various directions during driving, then the driver can check surroundings, but the driver must repeatedly take gaze away from the road when content is at a fixed position
Solution Approach 1:
The display content position is made dynamic rather than fixed, automatically tracking and adapting to the driver's head and gaze movements. This allows the driver to naturally look in different directions for situational awareness while the content remains consistently visible in the peripheral field of view
3Area of stationary object
If a large display device is used, then more information can be displayed, but it requires more head movement of the driver
Solution Approach 1:
The system compensates for the large display size by dynamically repositioning different portions of the displayed content based on the driver's gaze direction. Even though the display device has a large area, the control unit ensures that the relevant content portion is always positioned within the driver's current field of view, eliminating the need for excessive head movement

AI summary
The invention relates to a method of controlling a display device (10) in a vehicle (1). A content to be displayed by the display device (10) is provided. A drive situation dependent condition is determined and based on the determined drive dependent condition a view adjustment function is determined, the view adjustment function including a positional adjustment and a perspective adjustment of a view (11) of the content. An adjusted view (12) of the content is determined in accordance with the view adjustment function, and the content is displayed in the adjusted view (12) by the display device (10).
