Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

AR glasses often have bulky temples that obstruct peripheral vision, posing safety issues, especially during activities like driving.

Innovation Solution

Incorporating peripheral vision cameras and displays in the temples of AR glasses, with low resolution and high refresh rates, to recreate the user's peripheral vision, using machine learning to adjust the camera feed and provide an unobstructed view.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If temples of AR glasses are made thick to house components, then device functionality is improved, but peripheral vision is obstructed

Engineering Contradiction:

Improvedevice functionalityVSAvoidperipheral vision obstruction

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses outward-facing cameras to capture real-world peripheral scenes and displays these captured images on the inner surface of the temples, creating a visual copy of the peripheral environment that the user can view without removing the glasses

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces displays as an intermediary element between the user's eye and the obstructed peripheral view. The displays show camera-captured peripheral scenes, mediating the visual information delivery to bypass the physical obstruction caused by thick temples

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If displays with high refresh rates are used in temples, then peripheral vision recreation quality is improved, but power consumption increases

Engineering Contradiction:

Improveperipheral vision recreation qualityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies different quality parameters to different parts of the visual system: high refresh rates are used for peripheral displays where motion stability is critical, while the central AR display can use lower refresh rates, optimizing power distribution based on local visual requirements

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent uses low-resolution cameras for peripheral vision capture, which is sufficient for the peripheral field of view requirements but would be excessive for central vision. This partial action approach provides adequate peripheral recreation while conserving power

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A head-wearable apparatus includes a frame having a front piece configured to hold left and right lenses. A left temple is coupled to the front piece and a right temple coupled to the front piece. A camera system includes one or more cameras coupled to the front piece, one or more left peripheral cameras coupled to an outside surface of the frame, and one or more right peripheral cameras coupled to an outside surface of the frame. A left peripheral display is coupled to an inside surface of the frame. The left peripheral display is configured to receive and display input from the one or more left peripheral cameras. A right peripheral display is coupled to an inside surface of the frame. The right peripheral display is configured to receive and display input from the one or more right peripheral cameras.
