Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing augmented reality glasses and virtual reality goggles are ineffective in providing a wide field of view and accurate real-world vision for individuals with vision defects, such as macular degeneration, as they restrict peripheral vision and cause motion sickness due to limited field of view and latency issues.

Innovation Solution

A mixed reality wearable device that manipulates images to avoid damaged areas of the retina, projecting the image onto the peripheral receptors using a combination of hardware and software to provide a 'see through' experience, allowing users to see both real-world and augmented information simultaneously, with features like voice recognition, gesture recognition, and sensors for navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If VR goggles or traditional AR glasses with wave guides are used, then image augmentation is provided, but peripheral vision is restricted and field of view is limited

Engineering Contradiction:

Improveperipheral visionVSAvoidnavigation capability

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The display is segmented into multiple regions: a first region displaying augmented reality content and a second region displaying real-world visual information. This segmentation allows different types of visual information to be presented simultaneously in different portions of the user's field of view, preserving peripheral vision while providing augmentation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional VR/AR approaches that occupy the central visual field to a configuration where augmented content is displayed in a first region while real-world content occupies a second region, effectively utilizing different spatial dimensions of the visual field to avoid competition for the same visual space.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Illumination intensity

If VR goggles are used to augment sight, then image intensity and magnification are improved, but real-world sight is blocked and motion sickness occurs

Engineering Contradiction:

Improveimage intensityVSAvoidmotion sickness

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent merges augmented reality content and real-world visual information into a single unified display experience. Both types of content are presented simultaneously in different regions of the same display, allowing the user to access both enhanced imagery and real-world context without removing the device, thereby reducing motion sickness caused by disconnect between visual input and physical movement.

Inventive Principle:

Principle #5Merging (Combining)

3Loss of information

If traditional AR glasses with wave guides are used, then image augmentation is provided, but field of view is too small for accurate real-world vision

Engineering Contradiction:

Improvereal-world visual informationVSAvoidvision accuracy

Core Design Contradiction:

Loss of informationVSMeasurement precision

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

AI summary

A wearable mixed reality system comprising a camera input system, and image projection system capable of being worn by a user, and a processor in communication with the camera input system and the image projection system. The processor may be capable of receiving a real-world image from the camera input system and simultaneously displaying at least a portion of the real-world image and an augmented image on the image projection system such that a user views the portion of the real-world image and the augmented image simultaneously.
