3D Virtual Object Positioning via Multi-Direction Intersection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in allowing flexible positioning of virtual objects in three-dimensional spaces, particularly in augmented and virtual reality environments, as they restrict user instructions to linear adjustments, making it difficult to position objects on circular surfaces or in complex geometries.
Innovation Solution
An information processing apparatus that uses a display control unit to display a mark for a virtual object at an instruction position determined by multiple directions indicated by a user, allowing for flexible positioning by calculating the intersection of lines or directions indicated by controllers or the user's line of sight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a predetermined direction is determined in advance for displaying a stereoscopic object, then the system structure is simplified and easier to implement, but the user cannot flexibly position virtual objects on complex geometries such as circular surfaces
Solution Approach 1:
The patent transitions from a one-dimensional linear adjustment approach to a three-dimensional positioning system. By determining instruction positions based on multiple directions (at least two directions) simultaneously, the system enables users to specify positions in three-dimensional space, including on circular surfaces and other complex geometries, rather than being restricted to linear paths.
2Adaptability or versatility
If linear adjustment is used for position specification, then the instruction method is simple and intuitive, but it cannot accommodate positioning on circular surfaces or complex geometries
Solution Approach 1:
The patent creates a universal positioning method that works for various geometries including linear paths, circular surfaces, and complex three-dimensional structures. The instruction position determination unit can handle multiple types of geometric constraints by processing multiple directions simultaneously, making the system adaptable to different应用场景 while maintaining a consistent operation interface.
3Adaptability or versatility
If multiple directions are used to determine instruction position, then flexible positioning on complex geometries is enabled, but the calculation and processing complexity increases
Solution Approach 1:
The patent introduces an instruction position determination unit as an intermediary component that processes multiple directions and calculates the intersection point. This mediator handles the computational complexity of determining positions from multiple directions, shielding the user from the underlying complexity while enabling flexible positioning on complex geometries.
4Ease of operation
If a stereoscopic object is displayed along a predetermined direction, then the display system is straightforward to implement, but the user instruction is restricted and不够 flexible
Solution Approach 1:
The patent makes the instruction position dynamic by allowing it to be determined from multiple directions that can be adjusted in real-time. Instead of a fixed predetermined direction, the system dynamically calculates the instruction position based on at least two directions indicated by the user, enabling flexible positioning while maintaining ease of operation through intuitive directional indication.
