Solution Overview

Problem

Conventional 3D image interactive systems fail to provide a seamless user experience when the user is not at the default position, leading to shear distortion and inadequate response actions due to fixed trigger positions.

Innovation Solution

A position-bias compensation method that adjusts the trigger position in the interactive coordinate system based on the user's actual position relative to the default position, allowing for accurate response actions and improved interaction through modulated trigger positions and coordinates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed trigger position is used in the interactive coordinate system, then the system can provide consistent response actions at the default position, but the system fails to provide accurate interactions when the user is not at the default position

Engineering Contradiction:

Improveresponse action accuracyVSAvoiduser position adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The trigger position is changed from a fixed coordinate to a dynamic position that automatically adjusts based on the user's actual location. The system continuously updates the trigger position according to detected user position changes, enabling accurate interaction responses regardless of where the user stands in the interaction space.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system modifies the trigger position parameter in the interactive coordinate system based on the user's position bias relative to the default position. By calculating the displacement between actual and default positions, the system compensates the trigger position to maintain interaction accuracy across different user locations.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the trigger position is adjusted to accommodate user position variations, then user position adaptability is improved, but the system complexity increases due to position detection and calculation requirements

Engineering Contradiction:

Improveuser position adaptabilityVSAvoidposition detection and compensation system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements a feedback mechanism where the user's actual position is continuously detected and fed back to the control unit. Based on this feedback, the system calculates the position bias and automatically adjusts the trigger position to compensate for user location variations, creating a closed-loop control system.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The control unit acts as an intermediary between the position detection device and the interactive system. It receives position information, calculates the necessary compensation, and adjusts the trigger position accordingly, simplifying the overall system architecture by centralizing the compensation logic.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A position-bias compensation method, applied to a three-dimensional image interactive system, includes steps of: displaying a three-dimensional image and setting a trigger position in a preset interactive coordinate system according to a default position of a user; obtaining a position-bias of a user's position from the default position; and resetting the trigger position according to the position-bias.
