Solution Overview

Problem

Existing augmented reality (AR) content authoring techniques fail to effectively set the arrangement attitude of AR objects, leading to high user load and potential misalignment of AR content with real-world objects, which can result in incorrect interpretations by users.

Innovation Solution

A method using a computer to acquire display data associated with a reference object, generate attitude information based on user-applied rotation, and store setting information including the attitude information, identification of the reference object, and display data, allowing for intuitive and accurate setting of AR object attitudes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional AR content authoring techniques are used to set arrangement attitude, then AR content can be displayed, but user load increases and alignment accuracy decreases

Engineering Contradiction:

Improveease of setting arrangement attitudeVSAvoidalignment accuracy of AR content

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The system enables the user to directly control the arrangement attitude by rotating the terminal device itself, rather than requiring complex manual input operations. The rotation of the terminal device automatically translates to rotation of the AR object in the displayed image, making the system self-adjusting and intuitive.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces complex mechanical or manual adjustment mechanisms with sensor-based detection. By using the sensor to detect the rotation angle of the terminal device and automatically calculating the corresponding rotation parameters for the AR object, the system eliminates the need for manual parameter input and complex adjustment procedures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Extent of automation

If manual methods are used to set AR object attitude, then some control is possible, but the process is complex and error-prone

Engineering Contradiction:

Improveautomation of attitude settingVSAvoidcomplexity of authoring operations

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The terminal device performs self-detection of its rotation state through the sensor, and the system automatically calculates and applies the corresponding attitude parameters to the AR object. This self-service mechanism eliminates the need for complex manual configuration and reduces operational complexity significantly.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent substitutes manual mechanical adjustment with automated sensor-based detection and calculation. The sensor detects the terminal device's rotation, and the system automatically computes the transformation parameters, replacing complex manual operations with automated electronic processing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A setting method executed by a computer includes acquiring display data to be associated with a reference object detected from a first input image data and to be displayed when the reference object is detected from another input image, generating, by the computer, attitude information indicating an arrangement attitude of the display data relative to the reference object, based on rotation information indicating a magnitude of rotation that is applied to the computer by a user, and storing, in a storage device, setting information including the attitude information, the display data, and identification information of the reference object.
