Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Augmented reality glasses face issues with projected images being washed out in bright lighting conditions, leading to increased risk of falls or trips due to reduced visibility of real-world obstacles.

Innovation Solution

Implementing a dynamic opacity layer, such as the Optrx alpha matte technology, which adjusts lens opacity based on ambient light conditions using eye-tracking and software, allowing the lens to become opaque only where needed, enhancing the visibility of virtual images over real-world views.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the lens is shaded all the time to improve virtual image visibility in bright lighting, then the virtual image is no longer washed out, but the wearer becomes vulnerable to falls or trips over unseen obstacles

Engineering Contradiction:

Improvevirtual image visibilityVSAvoidsafety awareness

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The lens is divided into multiple zones with different opacity levels. The central region has higher opacity to enhance virtual image visibility, while peripheral regions maintain lower opacity to preserve awareness of real-world obstacles. This spatial segmentation allows simultaneous optimization of both virtual image quality and safety awareness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the lens are assigned different optical properties dynamically. The system adjusts the opacity of specific lens zones based on the location and characteristics of virtual images being displayed, allowing enhanced visibility where needed while maintaining transparency in other areas for safety awareness.

Inventive Principle:

Principle #3Local quality

2Illumination intensity

If the lens becomes opaque to enhance virtual image contrast in bright environments, then virtual images become clearly visible, but the wearer cannot see real-world obstacles

Engineering Contradiction:

Improvevirtual image contrastVSAvoidreduced visibility of real-world obstacles

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The lens opacity is dynamically adjusted rather than fixed. The system continuously adapts the opacity levels of different lens regions based on real-time conditions including ambient lighting, virtual image content, and user gaze direction, optimizing the balance between virtual image enhancement and real-world awareness.

Inventive Principle:

Principle #15Dynamics

3Illumination intensity

If a dynamic opacity layer is added to the lens to enable selective obscuring, then virtual image visibility is enhanced in bright lighting, but the device complexity increases

Engineering Contradiction:

Improvevirtual image visibility in bright lightingVSAvoidlens structure complexity

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The dynamic opacity layer is integrated within the existing lens structure rather than adding a separate external component. Multiple functional layers (reflective coating, anti-reflective coating, and dynamic opacity layer) are nested within each other, allowing the complex functionality to be embedded within the lens assembly without significantly increasing overall device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The dynamic opacity layer serves multiple functions simultaneously: it enhances virtual image visibility, controls glare from ambient light, and maintains safety awareness through selective transparency. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An augmented reality headset system is provided. The AR headset includes a camera, a lens subsystem, a micro-display, and a central processing unit. The lens subsystem includes a transparent layer with a first surface and an opposed second surface, a reflective coating applied to the first surface of the transparent layer, and an alpha matte layer abutting the second surface of the transparent layer. The central processing unit is programmed to execute an algorithm including the steps of displaying differential images on the lenses according to the position of the user's eye and displaying a plurality of pixels opaque in the portion of the alpha matte layer aligning with the portion of the reflective coating onto which the differential images are projected, while pixels aligning with any portion of the reflective coating onto which no image is projected remains transparent.
