Solution Overview

Problem

Existing 360° digital content rendering technologies restrict viewer access to only a limited viewing angle, typically up to 120°, requiring continuous head movements to explore the full content, which can be inconvenient and result in missed content.

Innovation Solution

A method and apparatus that generate an in-focal view covering the user's viewing angle and an out-focal view covering a wider angle using convex projection, allowing simultaneous display of both views to enhance content exploration without continuous head movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If 360° digital content is rendered with a limited viewing angle (up to 120°), then the rendering complexity is reduced and processing requirements are lowered, but the viewer's access to complete content is restricted and continuous head movements are required

Engineering Contradiction:
Improverendering complexityVSAvoidviewer access to content
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent divides the 360° content into multiple viewports (e.g., five viewports covering different angular ranges). Each viewport renders a portion of the complete content, allowing the system to manage rendering complexity by processing smaller angular segments independently while collectively providing full 360° coverage to the viewer

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension of viewing by rendering multiple simultaneous views (viewports) that cover different angular ranges of the 360° content. This allows the viewer to access content across multiple angular dimensions without requiring continuous head movements, effectively adding a spatial dimension to the viewing experience

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

2Ease of operation

If the viewing angle is increased to cover more content, then the viewer can see more content without head movements, but the rendering complexity and processing requirements increase

Engineering Contradiction:
Improveviewer access to contentVSAvoidrendering complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the wide-angle content into multiple manageable viewports, each covering a specific angular range. This segmentation allows the rendering system to process and display multiple views simultaneously without overwhelming computational requirements, as each viewport handles a smaller portion of the total 360° content

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements partial action by rendering only the necessary portions of the 360° content in each viewport based on the viewer's current orientation and the defined angular coverage requirements. This avoids rendering the entire 360° content at full resolution simultaneously, reducing processing complexity while still providing comprehensive content access

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A method for managing wide view content in a virtual reality (VR) environment and an apparatus therefor are provided. The method includes receiving content covering 360 degree or a wider viewing angle than a viewing angle of a user of the first device and displaying, on the VR device, a first view displaying at least one portion of the content covering the viewing angle of the user on a first view area of a display of the VR device, and a second view covering 360 degree or the wider viewing angle of the content using convex projection on a second view area of the display.
