AR Vehicle Light Overlay for Driver Sensory Overload
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of urban road environments leads to sensory overload in vehicle drivers due to asynchronous and varied exterior vehicle lights, which impairs cognitive functionality, situational awareness, and reaction times, increasing the risk of accidents.
Innovation Solution
An augmented reality (AR) synchronization system that assesses driver sensory overload through physiological and environmental data, superimposing synchronized computer-generated exterior vehicle lights over real-world lights via an AR display to reduce sensory overload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers are exposed to asynchronous exterior vehicle lights in complex urban environments, then drivers can perceive the true state of surrounding vehicles, but drivers experience sensory overload that impairs cognitive functionality and reaction times
Solution Approach 1:
The patent introduces an AR display as an intermediary between the driver and the external environment. The AR display superimposes synchronized virtual vehicle lights over the real asynchronous lights, creating a mediated visual experience that filters out the harmful asynchronous variations while preserving the essential information about vehicle states and intentions.
Solution Approach 2:
The system creates virtual copies of external vehicle lights through the AR display. These copied lights are synchronized to a common timing reference, allowing the driver to perceive accurate vehicle states without the distracting asynchronous variations present in the real-world lights.
2Loss of information
If multiple asynchronous turn signals are present in the environment, then drivers receive information about vehicle intentions, but the asynchronous nature creates visual and auditory distractions that increase sensory load
Solution Approach 1:
The patent merges multiple asynchronous turn signal sources into a single synchronized visual representation through the AR display. By combining the information from multiple vehicles and presenting it with unified timing and characteristics, the system reduces the complexity of sensory processing while maintaining the essential information about vehicle intentions.
Solution Approach 2:
The system changes the temporal parameters of external vehicle lights by synchronizing their flash timing through the AR display. This parameter transformation converts the harmful asynchronous variations into a unified, predictable timing pattern that is easier for the driver's sensory system to process.
3Reliability
If drivers maintain constant vigilance to ensure safety in complex environments, then accident risk is reduced, but drivers experience increased sensory load and cognitive fatigue
Solution Approach 1:
The AR synchronization system provides self-service by automatically filtering and synchronizing external light signals without requiring active driver intervention. The system continuously monitors and adjusts the virtual light representations, freeing the driver from the need to actively process each asynchronous signal while maintaining enhanced situational awareness.
