Virtual Content Positioning for Autonomous Vehicle Motion Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles pose a challenge in minimizing user motion sickness due to disorientation between visual motion of virtual content and the vehicle's actual motion, leading to discomfort during travel.
Innovation Solution
A computing system that determines the location of virtual content within a virtual environment based on the planned motion of the autonomous vehicle, ensuring it aligns with the vehicle's direction of travel and smoothly transitions between route segments, using visual indicators to aid the user's orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual content is displayed in a fixed location within the vehicle, then the display system is simple and stable, but the user experiences motion sickness due to disorientation between visual content and vehicle motion
Solution Approach 1:
The display system dynamically adjusts the location and orientation of virtual content based on the vehicle's planned motion trajectory. The virtual content is repositioned in the display field of view according to upcoming route segments, turns, and motion changes, transforming a static display system into an adaptive one that anticipates vehicle movement and maintains user orientation.
2Ease of operation
If virtual content location is adjusted frequently to match vehicle motion, then user orientation is maintained, but the transition between content locations causes additional disorientation
Solution Approach 1:
The system uses planned motion data to predict future vehicle trajectory and proactively positions virtual content at locations that will be optimal for upcoming route segments. By preparing the display in advance based on known planned motion, the system avoids sudden, disorienting transitions and maintains continuous user orientation throughout the journey.
3Ease of operation
If the virtual content is always positioned in the direction of vehicle travel, then the user remains oriented, but the display system requires complex calculations based on planned motion data
Solution Approach 1:
The system introduces an intermediary computational layer that processes planned motion data from the autonomous vehicle system and translates it into display coordinate transformations. This intermediary layer acts as a bridge between the vehicle's motion planning system and the display system, simplifying the overall complexity by creating a dedicated translation layer rather than requiring direct complex calculations in the display system.
