2D Ergonomic Interface for 3D Asset Placement in AR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing three-dimensional spaces for augmented or virtual reality content is challenging due to the difficulty in placing assets within the viewer's field of vision, as existing methods lack clear ergonomic guidelines for optimal placement and often require manual, complex processes to position assets correctly.
Innovation Solution
A method that converts a three-dimensional space into a two-dimensional ergonomic user interface using map projection schemas, allowing designers to place assets within ergonomic limits, and then re-converts it back to three dimensions for display, incorporating ergonomic limits and visual acuity heat maps for optimal placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If three-dimensional space is directly used for asset placement, then spatial accuracy is improved, but ease of operation deteriorates due to complexity of positioning in 3D space
Solution Approach 1:
The patent applies dimensionality change by converting the three-dimensional space into a two-dimensional map representation for asset placement. Designers interact with a 2D interface that represents 3D space, making placement easier while maintaining spatial accuracy through coordinate transformation. The system allows switching between 2D map view and 3D immersive view, resolving the contradiction by providing the appropriate dimension for each operation type.
2Adaptability or versatility
If manual positioning methods are used, then flexibility is improved, but productivity deteriorates due to time-consuming processes
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated coordinate transformation system. The system automatically converts 2D map coordinates to 3D spatial coordinates, eliminating time-consuming manual positioning while maintaining flexibility through the ergonomic interface. This substitution dramatically improves productivity while preserving design flexibility.
3Device complexity
If ergonomic limits are not considered, then device complexity is reduced, but ease of operation deteriorates due to suboptimal asset placement
Solution Approach 1:
The patent applies preliminary action by pre-defining ergonomic limits and parameters before the asset placement process. The system预先 establishes comfort zones, field of view constraints, and optimal placement regions based on human ergonomics. This preliminary configuration simplifies the interface by providing guided placement options while ensuring ergonomic optimality, resolving the contradiction between simplicity and optimality.

AI summary
Interface-based modeling and design of three dimensional spaces using two dimensional representations are provided herein. An example method includes converting a three dimensional space into a two dimensional space using a map projection schema, where the two dimensional space is bounded by ergonomic limits of a human, and the two dimensional space is provided as an ergonomic user interface, receiving an anchor position within the ergonomic user interface that defines a placement of an asset relative to the three dimensional space when the two dimensional space is re-converted back to a three dimensional space, and re-converting the two dimensional space back into the three dimensional space for display along with the asset, within an optical display system.
