Solution Overview

Problem

Current methods for displaying 4D light field data lack an automatic and user-centric approach to selecting content, such as focal plane and depth of field, which can lead to unsatisfactory user experiences.

Innovation Solution

A method that obtains user parameters and derives light field viewing parameters from statistics of interactions with 4D light field data by other users, allowing for personalized content selection and display adjustments, including viewpoint, refocusing, field of view, and visual effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automatic content selection from 4D light field data is implemented, then user satisfaction is improved, but system complexity increases

Engineering Contradiction:
Improveautomatic content selectionVSAvoidsystem complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically selects and displays content from 4D light field data based on user parameters and statistical interactions from other users, eliminating the need for manual user intervention in content selection while maintaining personalized experience

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses statistics representative of measured interactions with 4D light field data by other users to derive light field viewing parameters, creating a feedback loop that improves content selection based on collective user behavior patterns

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If personalized light field viewing parameters are derived from user parameters and statistics, then user preferences are satisfied, but data processing complexity increases

Engineering Contradiction:
Improvepersonalization capabilityVSAvoiddata processing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system pre-computes and stores statistics representative of measured interactions with 4D light field data by multiple users, so that when a new user accesses the system, personalized viewing parameters can be quickly derived without real-time complex analysis of all user interactions

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system introduces light field viewing parameters as an intermediary representation that bridges user parameters and the actual 4D light field data, simplifying the personalization process by working with derived parameters rather than directly manipulating complex 4D data structures

Inventive Principle:
Principle #24Intermediary (Mediator)
