Solution Overview

Problem

Current methods for predicting a driver's intention to perform a lane change maneuver are inadequate as they do not effectively utilize eye gaze data and traffic conditions to ensure safe and timely lane changes.

Innovation Solution

A system that monitors a driver's eye gaze using camera images and combines this data with traffic conditions to predict lane change intentions, learning from the driver's history to control the vehicle accordingly, and confirms the prediction through a human-machine interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the system monitors and analyzes driver eye gaze data combined with traffic conditions to predict lane change intentions, then the accuracy of intention prediction is improved, but the system complexity and computational requirements increase

Engineering Contradiction:
Improveintention prediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the intention prediction task into distinct analytical components: eye gaze direction detection, gaze duration measurement, traffic condition monitoring, and intention classification. This segmentation allows each component to be processed independently, improving prediction accuracy while managing system complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system adds temporal dimension by analyzing the duration and sequence of eye gaze patterns, transforming static gaze position data into dynamic behavioral indicators. This dimensional expansion enables more accurate intention prediction by capturing the evolution of driver attention over time, while the modular processing keeps complexity manageable.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of time

If the system processes real-time eye gaze data and traffic conditions to predict lane change intentions, then the timeliness of lane change execution is improved, but the computational load and processing time increase

Engineering Contradiction:
Improvelane change execution timeVSAvoidcomputational energy consumption
Core Design Contradiction:
Loss of timeVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary analysis of eye gaze patterns continuously during normal driving, building a baseline understanding of driver attention without triggering full prediction processing. When specific gaze patterns indicating lane change intention are detected, the system activates intensive analysis only at that moment, reducing overall computational energy consumption while maintaining timely response.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system applies partial processing by focusing computational resources only on the most probable intentions based on initial gaze analysis. Rather than evaluating all possible maneuvers equally, the system concentrates processing power on the specific lane change direction indicated by the driver's gaze, reducing computational load while maintaining prediction timeliness.

Inventive Principle:
Principle #16Partial or excessive action

3Reliability

If the system uses multiple parameters including eye gaze history and traffic conditions for prediction, then the reliability of safety assessment is improved, but the difficulty of data integration and processing increases

Engineering Contradiction:
Improvesafety assessment reliabilityVSAvoiddata integration difficulty
Core Design Contradiction:

Solution Approach 1:

The system introduces an intermediary processing layer that standardizes and normalizes data from multiple sources including eye gaze trackers, traffic sensors, and vehicle state monitors. This intermediary layer transforms heterogeneous data into a unified format, enabling reliable safety assessment through comprehensive parameter analysis while reducing the difficulty of data integration through systematic preprocessing.

Inventive Principle:
Principle #24Intermediary (Mediator)
