In-Vehicle Display Stabilization via Motion and Gaze Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle displays experience motion or vibration due to vehicle movement, causing motion sickness in occupants, which affects their physical and mental health.
Innovation Solution
A display apparatus equipped with a motion sensor, image capturing device, and circuitry that adjusts content display based on vehicle motion and eye gaze, using a machine learning model to determine the degree of adjustment for stabilizing the content displayed on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If in-vehicle displays are used during vehicle motion, then occupants can watch or read content, but motion sickness occurs due to vehicle motion and vibration
Solution Approach 1:
The system continuously captures motion signals from motion sensors and eye gaze data from the image capturing device, processes this feedback information through circuitry, and dynamically adjusts content display parameters including position, orientation, and stability to compensate for vehicle motion and reduce motion sickness
Solution Approach 2:
The display system transitions from a static display mode to a dynamic adaptive mode where content position, orientation, and stability parameters are continuously adjusted in real-time based on vehicle motion signals and occupant eye gaze data, enabling the display to adapt to changing motion conditions
2Object-affected harmful factors
If content is adjusted based on eye gaze and motion, then motion sickness is reduced, but device complexity increases due to additional sensors and processing
Solution Approach 1:
The image capturing device serves multiple functions: capturing occupant images for eye gaze determination, monitoring occupant position, and potentially other safety or interaction functions, thereby reducing the need for separate dedicated sensors and justifying the added complexity through multi-purpose utility

AI summary
A display apparatus and a mobile phone for content adjustment based on motion of a vehicle and an eye gaze of an occupant is provided. The display apparatus includes a display screen, a motion sensor, and an image capturing device. The display screen displays content. The display apparatus controls the motion sensor to capture a motion signal associated with the display apparatus. The display apparatus controls the image capturing device to capture an image of the occupant in the vehicle. The display apparatus determines a region of the eye gaze of the occupant on the display screen based on the captured image. The determined region on the display screen includes a portion of the displayed content. The display apparatus adjusts a movement of the portion of the displayed content in response to the captured motion signal being higher than a predefined threshold.
