Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality (AR) technologies face difficulties in setting a plane as a reference for displaying lines and accurately presenting virtual objects in real spaces, making tasks like object arrangement challenging.
Innovation Solution
An information processing apparatus that acquires user motion information to specify real surfaces in a real space and displays region images on corresponding virtual surfaces, allowing for easier arrangement of both virtual and real objects by determining the azimuth based on the real surface motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional AR technology is used to display virtual objects, then virtual space can be superimposed on real space, but it is difficult to set a plane as a reference and accurately present virtual objects in real space
Solution Approach 1:
The patent introduces a laser marking device as an intermediary tool that projects reference lines (crosshairs) onto real surfaces. This mediator establishes an accurate reference plane by projecting vertical and horizontal lines that intersect at a target point, enabling precise virtual object placement without requiring complex manual plane setting in the AR system itself.
Solution Approach 2:
The system performs preliminary action by pre-establishing reference planes and coordinate systems in the real space before virtual object placement. The laser marking device projects reference lines in advance to define the reference plane, and the AR system uses these pre-defined references to accurately position virtual objects, eliminating the need for complex real-time plane setting.
2Measurement precision
If laser marking device is used to project reference lines, then accurate reference plane can be established, but additional equipment and setup time are required
Solution Approach 1:
The patent merges the laser marking device functionality with the AR glasses system. The laser marking device is integrated or coordinated with the AR display system, allowing the reference lines to be projected and viewed simultaneously with the virtual objects. This combination reduces the need for separate equipment and streamlines the workflow by unifying the reference establishment and virtual object display processes.
3Adaptability or versatility
If manual plane setting is required in AR system, then flexibility is maintained, but work efficiency decreases due to complex arrangement tasks
Solution Approach 1:
The system implements feedback by continuously tracking the user's line of sight and head position through sensors in the AR glasses. This feedback mechanism allows the reference plane and virtual objects to automatically adjust and maintain accurate spatial relationships as the user moves, eliminating the need for manual re-setting while preserving flexibility. The system adapts to user movements automatically, maintaining both flexibility and efficiency.
