Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display devices provide limited user interfaces in 3D environments, as they primarily utilize 2D input methods to interact with 3D virtual objects, restricting user interaction and control within a 3D space.
Innovation Solution
A 3D display device comprising a display, a user input signal generator, and a controller that detects manipulating objects in a 3D space to generate user input signals, allowing for intuitive control of 3D virtual objects through tracking x, y, z coordinate information, and enabling interactions such as drag-and-drop operations, marker recognition, and image processing to provide a comprehensive user interface suitable for 3D environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a 2D user interface is used for 3D display devices, then the device can be operated with simple input methods, but the user interface becomes limited and not suitable for 3D environments
Solution Approach 1:
The patent transitions from 2D user interface to 3D user interface by detecting manipulating objects in three-dimensional space and generating corresponding user input signals. The 3D space includes x, y, z coordinates that map to virtual objects displayed in 3D, enabling intuitive spatial interaction that matches the dimensional nature of the displayed content.
2Device complexity
If 2D user interface methods are used to control 3D virtual objects, then the system structure remains simple, but the user interaction capability is restricted
Solution Approach 1:
The patent introduces a manipulating object as an intermediary between the user and the 3D virtual objects. This manipulating object serves as a mediator that users can physically handle and manipulate in 3D space, which then interacts with virtual objects through detected positions and orientations, enabling rich interaction without requiring complex direct control systems.
3Adaptability or versatility
If 3D space detection is implemented for user input, then user interaction in 3D environments is enhanced, but the detection and measurement complexity increases
Solution Approach 1:
The patent creates a correspondence between the physical manipulating object and its virtual representation in the 3D space. The system detects the manipulating object's position, orientation, and movement in physical space and copies this information to control the corresponding virtual object, simplifying the detection process by mapping physical measurements directly to virtual coordinates.
