Innovation Solution
An augmented reality content in-situ authoring method and apparatus that allows for fine adjustment of augmented object positions by dividing a three-dimensional space into cube areas, reconstructing sub-spaces, and integrating them to determine precise augmented positions and directions, using gaze tracking and body part pointing for selection, and registering meta information in a database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional general interaction methods in PC environment are used for authoring, then the system is simple to operate, but the efficiency and accuracy of placing virtual content in real space is low
Solution Approach 1:
The patent replaces conventional PC-based mechanical interaction methods with gaze tracking and body part pointing mechanisms. The authoring system detects the author's gaze direction and body part positions to automatically determine selection targets and placement positions, substituting manual cursor control and click operations with automatic detection-based interaction, thereby improving efficiency without significantly increasing operational complexity
Solution Approach 2:
The system enables self-service by automatically determining the placement position and selection target based on the author's natural gaze and body part movements. The authoring apparatus autonomously processes the placement operation by detecting gaze information and body part positions, eliminating the need for manual coordinate input or complex selection procedures, thus enhancing productivity while maintaining ease of use
2Measurement precision
If 3D space is divided into multiple cube areas for fine adjustment, then the placement precision is improved, but the device complexity increases
Solution Approach 1:
The patent divides the 3D space into multiple cube areas to enable fine-grained position adjustment of augmented objects. Each cube area represents a discrete placement zone, allowing precise control over where virtual content is positioned in real space. This segmentation approach transforms continuous space into manageable discrete units, improving measurement precision while keeping the system structure organized and manageable
Solution Approach 2:
The patent transitions from 2D screen interaction to 3D spatial positioning by dividing space into cube areas. The gaze tracking and body part pointing mechanisms operate in three-dimensional space, mapping the author's natural movements to precise 3D coordinates. This dimensional transition enables accurate placement in real space by utilizing depth and spatial relationships, thereby improving position precision without requiring overly complex control mechanisms

AI summary
Disclosed is an augmented reality content in-situ authoring method and apparatus. In an augmented reality content in-situ authoring method, a reference object or an augmented target object to be augmented may be selected from a camera preview image of a real world, a two-dimensional (2D) plane region may be recognized based on the selected reference object or the augmented target object and then a virtual 3D space may be constructed and divided based on the 2D plane region, and augmented reality content may be augmented through the divided space.
