Solution Overview

Problem

In virtual reality, users' freedom to control their point of view and location within a virtual space can lead to missed narrative incidents in cinematic content, disrupting the intended narrative experience due to the wider field of view and lack of directorial control.

Innovation Solution

Implementing a method that automatically mutes specific audio when the user is not in the correct location or point of view to prevent accidental exposure, and un-mutes it when the user returns to the relevant position, ensuring synchronized audio-visual content rendering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users are given freedom to control their point of view and location in virtual reality, then user exploration capability is improved, but narrative incident completion deteriorates

Engineering Contradiction:
Improveuser exploration capabilityVSAvoidnarrative incident completion
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system continuously monitors user location and point of view, comparing actual positions against required positions for narrative incidents. This feedback mechanism triggers automatic point-of-view adjustments or user notifications when deviations occur, ensuring narrative incidents are not missed while preserving user exploration freedom.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system pre-defines required point of view and location parameters for each narrative incident before the user experiences the content. These predetermined parameters enable the system to proactively guide or adjust user perspective to ensure critical narrative moments are captured, preventing narrative completion issues before they occur.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If directorial control is maintained over narrative points of view, then narrative incident completion is improved, but user exploration freedom deteriorates

Engineering Contradiction:
Improvenarrative incident completionVSAvoiduser exploration freedom
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts the level of directorial control based on user behavior and narrative context. When users are engaged in exploration during non-critical segments, full user freedom is maintained. When approaching narrative incidents, the system automatically applies directorial point-of-view control to ensure incident completion, creating a dynamic balance between freedom and narrative reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The virtual reality content is segmented into distinct narrative incident segments and exploration segments. During exploration segments, users have complete freedom to move and change point of view. During narrative incident segments, directorial control is activated to guide user perspective. This segmentation allows both user exploration freedom and narrative incident completion to be optimized in their respective contexts.

Inventive Principle:
Principle #1Segmentation

3Reliability

If automatic point of view control is applied during narrative incidents, then narrative incident completion is improved, but user perspective control deteriorates

Engineering Contradiction:
Improvenarrative incident completionVSAvoiduser perspective control
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Automatic point of view control is applied periodically only during specific narrative incident time windows, rather than continuously. Between these periodic control intervals, users retain full perspective control for exploration. This periodic application minimizes interference with user operation while ensuring narrative incidents are captured at their critical moments.

Inventive Principle:
Principle #19Periodic action

AI summary

A method is provided, comprising: preventing rendering of specific audio in a virtual space to a user through virtual reality; enabling the user to explore the virtual space through user-perspective controlled virtual reality without hearing the specific audio; and in response to an interrupt, performing a visual transition to audio-visual content comprising the specific audio and visual content associated with the specific audio and then rendering specific audio and the visual content associated with the specific audio in the virtual space to the user through virtual reality.
