Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Reckless driving behaviors caused by unsafe emotional states, such as annoyance, anger, anxiety, and depression, significantly impair a driver's ability to react to road hazards, leading to traffic accidents, and existing methods lack adaptive systems to effectively detect and alter these states.

Innovation Solution

A system utilizing machine learning algorithms to classify a driver's mood through facial imagery and physiological data, dispersing specific scents to improve their mood, with the system learning and adapting to individual responses over time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If scents are used to alter driver mood, then emotional safety is improved, but individual variability in scent response reduces effectiveness

Engineering Contradiction:

Improvemood alteration effectivenessVSAvoidindividual scent response variability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts to individual drivers by continuously learning their scent responses through machine learning. The system adjusts scent selection and dispersion based on real-time mood detection and historical response data, transforming a static scent delivery approach into a dynamic, personalized intervention strategy that evolves with each driver's unique physiological and psychological patterns

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements closed-loop feedback by monitoring driver mood through facial cameras and physiological sensors, dispensing scents based on detected emotional states, and then evaluating the resulting mood changes. This feedback mechanism allows the system to learn from each interaction and refine future scent selections, converting individual variability into personalized effectiveness through continuous adaptation

Inventive Principle:

Principle #23Feedback

2Measurement precision

If machine learning is used to personalize scent responses, then mood alteration precision is improved, but system complexity increases

Engineering Contradiction:

Improvemood classification accuracyVSAvoidsystem architecture complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system employs a multi-functional architecture where a single machine learning platform performs multiple tasks: classifying driver mood from facial imagery, predicting scent response outcomes, and selecting optimal scent interventions. This universal approach consolidates what could be separate complex systems into one integrated solution, reducing overall system complexity while maintaining high precision through the coordinated operation of interconnected modules

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If continuous monitoring of driver mood is implemented, then safety awareness is improved, but energy consumption increases

Engineering Contradiction:

Improvedriver safety monitoringVSAvoidsystem energy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system employs periodic monitoring rather than continuous operation, activating facial camera analysis and physiological sensing at strategic intervals based on driving conditions and detected mood thresholds. This periodic approach maintains adequate safety monitoring while significantly reducing energy consumption compared to constant surveillance, allowing the system to balance safety requirements with power conservation in the vehicle environment

Inventive Principle:

Principle #19Periodic action

AI summary

System, method and media for altering the mood of an occupant (such as a driver) of a vehicle. Reckless operation of motor vehicles by emotionally disturbed drivers is a major cause of traffic accidents just like alcohol, drug, and cell phone use. Emotional states such as annoyance, anger, anxiety, depression, and feeling hurried can significantly impair awareness by slowing observation and reaction times. Scents, both pleasant and unpleasant, have major effects on mood and sense of well-being. Accordingly, embodiments of the invention provide for an adaptive system which can detect a driver's mood, disperse an appropriate scent to improve the mood if it is unsafe, and learn the impact of scents on different users to effectively improve their moods.
