Solution Overview

Problem

Current volumetric image display technologies lack an intuitive user interface that allows natural manipulation of three-dimensional rendered objects, similar to interacting with real objects, as they fail to provide effective visual feedback and accurate location recognition in a 3D space.

Innovation Solution

A volumetric image display device comprising a recognition unit, a visual indicator location determining unit, and a display unit that recognizes input objects in a 3D recognition space, determines the location of a visual indicator in a volumetric image display space, and displays it to provide visual feedback, enabling users to manipulate volumetric images naturally by simulating touch and proximity interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If volumetric image display technology is used to display 3D-rendered objects, then the visualization capability is improved, but the intuitiveness of user interaction deteriorates due to lack of effective visual feedback and accurate location recognition

Engineering Contradiction:
Improvevisualization capabilityVSAvoidintuitiveness of user interaction
Core Design Contradiction:
Illumination intensityVSEase of operation

Solution Approach 1:

The patent implements visual feedback by displaying a visual indicator at the recognized location of the input object in the volumetric image display space. This feedback mechanism allows users to see where their hand or input device is positioned in 3D space, enabling intuitive interaction with volumetric images without physical contact.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces a visual indicator as an intermediary element between the user's input object and the volumetric image. This visual indicator serves as a mediator that bridges the gap between physical input and digital manipulation, allowing natural hand movements to control volumetric images in air.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If location recognition in 3D space is implemented, then the accuracy of interaction is improved, but the complexity of the system increases due to need for recognition unit and coordinate transformation

Engineering Contradiction:
Improveaccuracy of location recognitionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The recognition unit serves multiple functions: it recognizes the input object's location, determines coordinates in both 3D recognition space and volumetric image display space, and enables interaction control. This multi-functionality reduces the need for separate components for each function, thereby managing system complexity while maintaining high location recognition accuracy.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If visual indicator is displayed based on input object location, then the naturalness of interaction is improved, but the loss of information increases due to location estimation errors

Engineering Contradiction:
Improvenaturalness of interactionVSAvoidlocation estimation errors
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The visual indicator provides continuous visual feedback about the recognized location of the input object. This feedback allows users to see and correct any location estimation errors in real-time, maintaining natural interaction while compensating for information loss through visual confirmation and adjustment.

Inventive Principle:
Principle #23Feedback
