Subliminal Sensory System for Autonomous Vehicle Motion Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers in autonomous vehicles often experience trust issues and motion sickness due to disalignment between their sensory perceptions and the vehicle's operational forces, particularly when not actively engaged with the vehicle's operation.
Innovation Solution
A system comprising sensors, a processor, and a subliminal sensory system, such as lighting, sound, or haptic systems, that provide subconscious cues about the vehicle's operational status and anticipated forces to align passenger sensory perceptions with the vehicle's motion, thereby enhancing trust and reducing motion sickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous vehicle operates autonomously without driver input, then the ease of operation is improved, but passenger trust deteriorates due to lack of awareness about vehicle decisions
Solution Approach 1:
The system provides continuous feedback to passengers through the subliminal sensory system, displaying vehicle status, sensor detections, and decision-making information. This feedback loop maintains passenger trust by keeping them informed about autonomous vehicle operations without requiring active monitoring or input from the passenger.
Solution Approach 2:
The subliminal sensory system acts as an intermediary between the autonomous vehicle's operational systems and the passenger. It translates complex vehicle status data into subtle sensory cues that passengers can perceive, bridging the information gap between the autonomous system and the passenger without requiring direct passenger engagement.
2Reliability
If the vehicle provides detailed information about operational status, then passenger trust is improved, but the complexity of the system increases
Solution Approach 1:
Instead of displaying complex raw sensor data and operational parameters, the system creates simplified visual copies or representations of vehicle status. The subliminal sensory system generates subtle visual cues that represent operational information in an easily perceptible format, maintaining trust without adding complex display interfaces.
Solution Approach 2:
The system changes the parameter of information presentation from detailed, explicit data to subtle, implicit sensory cues. By transforming the nature of information delivery from conscious visual displays to subliminal sensory feedback, the system maintains passenger awareness without increasing interface complexity.
3Object-affected harmful factors
If the vehicle provides sensory cues about operational forces, then motion sickness is reduced, but the complexity of the sensory system increases
Solution Approach 1:
The system merges the subliminal sensory cue generation function with existing vehicle display systems. By integrating the motion sickness mitigation capability into the existing visual display infrastructure rather than adding separate dedicated hardware, the system reduces harmful effects without proportionally increasing overall system complexity.
Solution Approach 2:
The subliminal sensory system serves multiple functions simultaneously: it provides trust-building feedback about vehicle operations, delivers motion sickness mitigation cues, and maintains passenger awareness. This multi-functionality allows the system to address multiple problems with a single integrated solution rather than requiring separate systems for each function.
Data Source
AI summary
A system for promoting passenger trust and to mitigate motion sickness in a vehicle may include a first sensor structured to detect an operational status of the vehicle, a processor operably coupled to the first sensor; and a subliminal sensory system operably coupled to the processor. The processor may be structured to control the subliminal sensory system to subliminally provide information about the operational status of the vehicle to a passenger.
