Ceiling Skyview Display Synchronized With Vehicle Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motion sickness in vehicle occupants is exacerbated by incongruent sensory perceptions, particularly when rear-seat passengers experience mismatched visual and acceleration cues, and existing roof-mounted entertainment displays obscure the view and contribute to this issue.
Innovation Solution
Implementing a system that uses car sensors to project an artificial sky view on headliner-mounted displays, synchronizing the visual content with the vehicle's motion, using sensors like accelerometers, gyroscopes, and GPS to adjust the displayed sky view in real-time to match the occupant's actual motion, thereby reducing sensory mismatch and motion sickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If roof-mounted entertainment displays are folded upwards to the ceiling, then entertainment multimedia and trip information can be displayed to occupants, but the displays obscure the clear view of the user to the sky
Solution Approach 1:
The patent creates a virtual copy of the sky view and projects it onto the ceiling display surface. This allows the display to show sky content without physically blocking the actual sky view, resolving the contradiction between providing display functionality and maintaining sky visibility.
Solution Approach 2:
The patent introduces a camera and projection system as intermediaries to capture the real sky view and reproduce it on the ceiling. This intermediary system allows occupants to view the sky through the display without the display physically obstructing the view.
2Adaptability or versatility
If conventional displays are mounted on the roof, then entertainment content can be provided to occupants, but incongruent sensual perceptions cause motion sickness in rear-seat passengers
Solution Approach 1:
The system captures the real sky view through a camera and projects it onto the ceiling display, creating a virtual environment that moves with the vehicle. This synchronized visual feedback reduces sensory conflict and motion sickness while maintaining entertainment capability.
Solution Approach 2:
The system uses motion sensors to detect vehicle movement and dynamically adjusts the projected sky view in real-time to match the vehicle's motion. This feedback mechanism ensures visual consistency with physical sensation, reducing motion sickness.
3Area of stationary object
If head-mounted displays are used to provide sky view, then the view obstruction problem is avoided, but device complexity and user comfort are reduced
Solution Approach 1:
The patent merges the display function with the existing ceiling structure by projecting the sky view directly onto the headliner. This integration eliminates the need for separate head-mounted displays while maintaining sky view availability and reducing overall system complexity.

AI summary
Disclosed are a vehicle and a method for reducing motion sickness of an occupant (1) of a vehicle (10). The method comprises the steps: • Displaying a section of a skyview (A, B, C) on a ceiling display (2) of the vehicle (10) • Detecting a motion of the vehicle (10), namely - a vertical motion of the vehicle (10) and/or - a rotation of the vehicle (10) around a horizontal axis and • Adjusting the displayed section of the skyview (A, B, C) corresponding to the detected motion of the vehicle (10).
