Augmented Reality HUD Pedestrian Yielding Overlay

Solution Overview

Problem

Drivers often engage in unsafe behaviors behind the wheel due to lack of effective feedback, leading to potential deadly consequences, as existing systems either distract or fail to correct unsafe driving habits effectively.

Innovation Solution

A system using augmented reality to guide drivers safely by determining turn lanes, detecting pedestrians, and spatially overlaying yielding indications on a volumetric heads-up display, providing visual feedback to promote safe driving behaviors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If text display or voice feedback systems are used to provide driver performance feedback, then driver behavior correction is attempted, but the driver becomes distracted rather than effectively prompted toward safe driving behavior

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an augmented reality display as an intermediary between the driver and the road environment. This display overlays safety cues and pedestrian detection information directly onto the driver's field of view, mediating the interaction between the driver and potential hazards without requiring the driver to shift attention to separate displays or audio cues.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transitions from two-dimensional text or audio feedback to a three-dimensional spatial overlay system. By projecting safety information into the driver's forward view at various depths and positions, the system adds a spatial dimension to feedback delivery, allowing information to be presented in context with the actual road environment rather than as separate abstract cues.

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

2Reliability

If traditional feedback systems are used to address unsafe driving habits, then driver performance is monitored, but the feedback fails to effectively correct dangerous behaviors due to lack of engagement

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a real-time feedback loop where the system continuously monitors the driving environment, detects pedestrians and potential hazards, and immediately provides visual feedback through the augmented reality display. This closed-loop feedback system allows drivers to see the consequences of their actions in real-time, such as seeing detected pedestrians overlaid on the road ahead, which reinforces safe driving behavior more effectively than delayed or abstract feedback.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent utilizes color changes and visual transformations in the augmented reality display to convey different safety states. By changing the appearance of overlaid elements based on detected conditions (such as highlighting pedestrians in specific colors or intensifying visual cues when hazards are detected), the system creates engaging and immediately recognizable feedback that captures driver attention and promotes behavioral correction.

Inventive Principle:
Principle #32Color changes

3Reliability

If volumetric heads up display with augmented reality overlay is implemented, then driver engagement and safety cue clarity are improved, but system complexity increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a multi-functional system where the augmented reality display serves multiple purposes: it displays pedestrian detection information, provides safety cues, overlays spatial context, and delivers behavioral feedback all through a single integrated interface. This universal approach consolidates what would otherwise require multiple separate systems into one cohesive display mechanism, managing complexity through functional integration rather than proliferation of components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An augmented reality driver system, device, and method safely guide a vehicle driver to yield to pedestrians. A vehicle navigator determines a turn lane based upon proximity to a vehicle. A target sensor detects a pedestrian entering the turn lane and to determine a crosswalk path across the turn lane. An augmented reality controller three dimensionally maps a forward view including the pedestrian, and spatially overlays an augmented reality display on the volumetric heads up display for a driver of the vehicle by projecting a yielding indication adjacent to the crosswalk path.
