In-Vehicle Display Control for Motion Sickness and Content Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle display devices often cause car sickness due to discrepancies between vestibular and visual information, and existing solutions fail to effectively balance the display of image content with anti-carsickness content to mitigate this issue.
Innovation Solution
An in-vehicle display device that adjusts the ratio and brightness of image content and anti-carsickness content based on content variation and viewer tolerance, using sensors to detect viewer response, to minimize car sickness while maximizing image content visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image content is displayed to maximize visibility, then viewer enjoyment is improved, but car sickness increases due to sensory conflict
Solution Approach 1:
The display device dynamically adjusts the display area ratio between image content and anti-carsickness content based on the amount of content variation. When content variation is high (more likely to cause carsickness), the display area of anti-carsickness content is increased relative to image content, creating a dynamic balance that adapts to changing conditions
Solution Approach 2:
The system changes the display parameter (display area ratio) based on the amount of content variation in the image content. By monitoring content variation and adjusting the display area ratio accordingly, the system optimizes the balance between image visibility and carsickness prevention
2Object-affected harmful factors
If anti-carsickness content display area is increased to suppress car sickness, then car sickness is reduced, but image content visibility decreases
Solution Approach 1:
The display area ratio is not fixed but dynamically adjusted based on content variation. When content variation is low (less likely to cause carsickness), the display area of image content can be maximized. When content variation is high, the display area of anti-carsickness content is increased, creating an optimal balance at different times
Solution Approach 2:
The system applies anti-carsickness content not always at full strength but adjusts its display area based on need. When content variation is high, more anti-carsickness content is displayed. When content variation is low, less anti-carsickness content is displayed, allowing more image content to be visible
3Object-affected harmful factors
If display area ratio is adjusted based on content variation, then optimal balance is achieved, but device complexity increases
Solution Approach 1:
The display device automatically determines the amount of content variation and adjusts the display area ratio without requiring manual intervention. The system self-regulates by monitoring its own content and making appropriate adjustments, reducing the need for complex external control mechanisms

AI summary
The processor displays the image content and the anti-carsickness content for suppressing car sickness of the viewer on the display unit. The processor changes the ratio of the display area of the image content to the display area of the anti-carsickness content so that the larger the variation of the image content, the smaller the display area of the image content to the display area of the anti-carsickness content. Alternatively, the processor changes the ratio of the display area of the image content to the display area of the anti-carsickness content so that the lower the viewer's tolerance for carsickness, the smaller the display area of the image content to the display area of the anti-carsickness content.
