Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing XR systems cause user discomfort due to attempted display of virtual content outside the stereoscopic field of view, leading to doubled images and reduced 3D perception.

Innovation Solution

The XR system clips virtual content outside the user's stereoscopic field of view using a clipping mask based on the user's field of view, generating a monoscopic view to prevent discomfort and maintain 3D perception.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If virtual content is displayed outside the user's stereoscopic field of view, then the quantity of displayed content increases, but user comfort deteriorates and depth perception is lost

Engineering Contradiction:

Improvequantity of displayed virtual contentVSAvoiduser discomfort and loss of depth perception

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes virtual content that falls outside the user's stereoscopic field of view, retaining only the portion of virtual content that is within the stereoscopic field. This extraction process eliminates the harmful effects of displaying content outside the field of view while preserving the beneficial content within the field, thereby resolving the contradiction between quantity of content and user comfort.

Inventive Principle:

Principle #2Taking out (Extraction)

2Area of stationary object

If virtual content is displayed outside the user's stereoscopic field of view, then the coverage area increases, but image quality deteriorates due to doubled images

Engineering Contradiction:

Improvecoverage area of virtual contentVSAvoidimage quality

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The system extracts only the portion of virtual content that lies within the user's stereoscopic field of view and discards the portion outside this field. This selective extraction prevents the generation of doubled images while maintaining comprehensive coverage within the valid field of view, thus improving image quality without sacrificing necessary coverage.

Inventive Principle:

Principle #2Taking out (Extraction)

3Volume of stationary object

If virtual content is displayed outside the user's stereoscopic field of view, then the display volume increases, but depth perception deteriorates

Engineering Contradiction:

Improvedisplay volume of virtual contentVSAvoiddepth perception accuracy

Core Design Contradiction:

Volume of stationary objectVSMeasurement precision

Solution Approach 1:

The patent applies extraction by removing virtual content that falls outside the user's stereoscopic field of view, keeping only content that maintains proper depth relationships. This ensures that the displayed virtual content preserves accurate depth perception while still providing comprehensive coverage within the stereoscopic field, resolving the contradiction between display volume and depth perception accuracy.

AI summary

An eXtended Reality (XR) system provides methodologies for clipping virtual content displayed to a user. The XR system generates an XR user interface with virtual content using an XR user interface model. The XR system generates clipped virtual content from the virtual content by clipping virtual content that is located outside of the user's stereoscopic field of view and provides the XR user interface containing the clipped virtual content to the user.
