3D Input Space Tracking Stability via Virtual Anchor Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented interactive input systems face issues with temporary loss of tracked physical objects due to obscured or out-of-view patterns, leading to flickering digital content and lack of visual feedback during manipulation in 3D input spaces.
Innovation Solution
A computerized method and system that displays a 2D image of a 3D object with control regions for rotation, recognizes patterns on physical objects within a 3D input space, and modifies the image based on object states and user proximity, providing visual feedback and maintaining digital content association.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If augmented interactive input systems use document cameras to track physical objects with recognizable patterns, then digital content can be superimposed and manipulated through physical object manipulation, but temporary loss of tracked objects occurs when patterns are obscured or out of field of view, causing flickering digital content
Solution Approach 1:
The patent introduces a virtual anchor point as an intermediary between the physical object and the digital content. When the physical object is lost from view, the system maintains association between the virtual anchor point and the digital content, preventing flickering. The virtual anchor point acts as a mediator that persists through temporary tracking losses, ensuring continuous display of digital content even when the physical object is obscured or out of frame.
Solution Approach 2:
The system implements feedback mechanisms to detect when physical objects are lost from view and automatically adjusts the display accordingly. When tracking is lost, the system provides feedback by maintaining the virtual anchor point association, ensuring the digital content remains visible and stable. This feedback loop prevents the flickering effect by continuously monitoring and responding to tracking status changes.
2Adaptability or versatility
If physical objects are manipulated in 3D input space, then digital content can be associated with objects, but visual feedback is lost when patterns are obscured by fingers or hands
Solution Approach 1:
The patent creates a virtual copy (virtual anchor point) of the physical object's spatial position and association with digital content. This virtual copy persists independently of the physical object's visibility, providing continuous visual feedback. When fingers or hands obscure the physical object's pattern, the virtual anchor point maintains the visual representation, ensuring uninterrupted feedback to the user during manipulation.
3Shape
If standard 2D interfaces are used to control 3D objects, then 3D visualization can be preserved, but direct 3D manipulation capability is lost
Solution Approach 1:
The patent extends the 2D interface into the 3D space by allowing physical objects to be placed and manipulated within a three-dimensional input space. The system maps physical object positions and orientations in 3D space to corresponding virtual anchor points and digital content representations. This dimensional extension enables direct 3D manipulation while preserving visualization, as users can physically point to and manipulate objects in the 3D space rather than using abstract 2D cursors.
Data Source
AI summary
Computerized methods and interactive input systems for manipulation of 3D objects are disclosed. An image of 3D object is displayed on a 2D interactive surface, and input is received and is interpreted for manipulating the 3D object. When the 3D object is selected, rotation control handles indicating available rotation directions are displayed. In one embodiment, the method comprises capturing images of a 3D input space, recognizing at least one object in the images, and comparing the recognized objects in the images to determine a difference therebetween based on a difference threshold. Depending on the outcome of the comparison, the recognized objects are emerged and associated with digital content, or only one of the recognized objects is maintained and associated with digital content.
