AR Virtual Object Positioning via Visual Field Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In augmented reality applications, users face inconvenience when trying to maintain virtual objects within their visual field during physical activities, as they need to manually reposition these objects, limiting the use of AR products as alternatives to mobile devices for providing audio and visual instructions.
Innovation Solution
A display method and system that uses a processor to recognize characteristics of a main object in a video, determine a target point, calculate position relationships, and control a display device to dynamically position a virtual object in a virtual environment, ensuring it remains visible to the user without manual adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the virtual display screen stays at a fixed position in reference to the real scene, then it can simulate a real display device, but the user has to manually reposition it when it leaves the visual field during physical activities
Solution Approach 1:
The patent applies dynamics by transitioning the virtual display screen from a static fixed position to a dynamic position that automatically adjusts based on user movement and visual field conditions. The system continuously tracks user position and orientation, then dynamically repositions the virtual screen to maintain visibility during physical activities, eliminating manual repositioning while preserving the simulation of a real display device.
Solution Approach 2:
The system implements self-service by enabling the virtual display screen to automatically reposition itself without user intervention. The processor monitors user visual field status and autonomously adjusts the virtual screen's position and orientation to keep it within the visual field during physical activities, making the system self-adjusting and convenient for users.
2Ease of operation
If the virtual display screen is manually repositioned by the user, then it can remain in the visual field, but this causes inconvenience during physical activities
Solution Approach 1:
The system applies preliminary action by continuously monitoring user position and visual field conditions in advance, before the virtual display screen leaves the visual field. The processor predicts when repositioning will be needed and proactively adjusts the virtual screen's position, preventing it from leaving the visual field in the first place. This eliminates the need for reactive manual repositioning and saves user time during physical activities.
Solution Approach 2:
The patent implements feedback by creating a closed-loop system where the processor continuously receives data about user position and visual field status, processes this information, and automatically adjusts the virtual display screen's position accordingly. This real-time feedback mechanism ensures the virtual screen remains visible during physical activities without requiring manual intervention, reducing both inconvenience and time loss.
3Adaptability or versatility
If the virtual display screen remains fixed, then the system is simple to operate, but AR products cannot effectively replace mobile devices for providing audio and visual instructions
Solution Approach 1:
The patent applies universality by designing a positioning system that serves multiple functions: it tracks user position, monitors visual field status, determines orientation, and automatically repositions the virtual display screen. This multi-functional system enables AR products to effectively replace mobile devices for providing audio and visual instructions during physical activities, enhancing adaptability without requiring separate systems for each function.
Solution Approach 2:
The system replaces manual mechanical repositioning operations with an automated electronic control system. The processor uses sensor data and computational algorithms to automatically adjust the virtual display screen's position, substituting the mechanical action of manual dragging and dropping with an electronic automated positioning mechanism. This reduces device complexity perception while significantly improving AR product functionality and versatility.
