AR Artificial Horizon for Motion Sickness Relief in Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Motion sickness occurs due to conflicting sensory information when a person's visual attention is focused on an unmoving element within a vehicle's frame of reference, causing discomfort, nausea, dizziness, and fatigue, as the eyes do not perceive movement while the inner ear detects vehicle motion.
Innovation Solution
A system comprising a sensor to measure vehicle movement data, an artificial horizon device generating a real-time image of an artificial horizon, and a wearable augmented reality device to display this image, ensuring visual information aligns with inner ear data, thereby reducing motion sickness symptoms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual attention is focused on an unmoving element within the vehicle's frame of reference, then the individual can maintain visual focus on a specific object, but conflicting sensory information causes motion sickness symptoms
Solution Approach 1:
The patent introduces an artificial horizon as an intermediary visual element that mediates between the unmoving vehicle interior and the moving external environment. This artificial horizon, displayed through augmented reality glasses, provides visual feedback about vehicle movement without requiring the passenger to look outside, thus resolving the conflict between visual stability and motion perception
Solution Approach 2:
The system implements feedback by continuously displaying the artificial horizon that reflects real-time vehicle movement data. Sensors detect vehicle acceleration and orientation, and this data is immediately translated into visual updates of the artificial horizon, providing continuous feedback that aligns visual perception with vestibular sensation to prevent motion sickness
2Stability of the object's composition
If the eyes focus on a stationary object inside the vehicle, then visual stability is maintained, but the inner ear perceives vehicle movement creating sensory conflict
Solution Approach 1:
The artificial horizon serves as an intermediary that bridges the stationary vehicle interior and the moving external world. It provides movement information without requiring the passenger to shift visual focus from interior objects, thus maintaining visual stability while preventing information loss about vehicle motion
Solution Approach 2:
The patent adds a new dimension of visual information by overlaying the artificial horizon in augmented reality space. This creates an additional layer of visual data that conveys movement information without interfering with the primary visual focus on stationary interior objects, effectively adding information in a different dimensional space
