In-Vehicle Horizontal Line Display for Motion Sickness Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motion sickness reducing systems fail to provide visual information about the vehicle's inclination relative to the horizontal, which is crucial for addressing balance-related motion sickness.
Innovation Solution
A display device in the vehicle's riding space displays a horizontal line orthogonal to the vehicle's gravitational direction, regardless of its inclination, optionally accompanied by a road condition detection unit and bright spots moving along the line to match acceleration/deceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display shows vehicle motion flow patterns, then dynamic motion information is provided, but static horizontal reference information is missing
Solution Approach 1:
The horizontal line is displayed as a pre-established reference framework before and during the presentation of motion flow patterns. This preliminary visual reference allows riders to immediately contextualize the dynamic motion information within a stable horizontal orientation framework, preventing the loss of horizontal reference information.
2Reliability
If the optical array mimics specific vehicle movements, then motion correspondence is achieved, but balance-related motion sickness is not adequately addressed
Solution Approach 1:
The horizontal line display provides continuous visual feedback about the vehicle's inclination relative to horizontal, complementing the motion flow patterns. This feedback mechanism gives riders accurate information about their orientation, allowing their vestibular system to reconcile visual and balance inputs, thereby reducing motion sickness while maintaining accurate motion correspondence.

AI summary
There is provided a motion sickness reducing apparatus capable of providing visual information to an individual on a vehicle as to how much he or she is tilted to the horizontal (as a result, motion sickness caused by sense of balance can be reduced.). The motion sickness reducing apparatus includes a display device that is provided in a riding space of a vehicle having the riding space in which an individual rides and displays a horizontal line extending in a horizontal direction orthogonal to a gravity direction of the vehicle in a riding space regardless of a tilt of the vehicle.
