Dual Handling Field for 3D Display Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The miniaturization of smart devices limits user interaction due to anatomical constraints, making it difficult to control complex display parameters on small screens, especially for tasks like 3D visualization and efficient data entry, which require more handling options than available in traditional two-dimensional interfaces.
Innovation Solution
The implementation of a dual handling field system on smart devices, where one field is used for data entry and another for controlling display parameters, allowing users to manipulate images in three dimensions using coordinated finger movements, without occupying significant display space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the display size is reduced for miniaturization, then the device size decreases, but the area available for controlling display parameters is reduced
Solution Approach 1:
The patent transitions from two-dimensional touch control to three-dimensional handling field control. The handling field can be displaced along three mutually normal directions (x, y, z axes), enabling control of multiple display parameters (position, scale, rotation) in three-dimensional space without increasing the physical display area. This dimensional expansion resolves the contradiction by providing sufficient control capability within a miniaturized device form factor.
Solution Approach 2:
The handling field serves multiple functions: it controls picture position, scale, rotation, and can navigate between different layers of three-dimensional data. This multi-functionality allows a single compact component to replace what would traditionally require multiple separate controls, enabling comprehensive display parameter control within the constrained area of miniaturized devices.
2Adaptability or versatility
If more display parameters are controlled to enable complex functions like 3D visualization, then the functionality increases, but the complexity of control operations increases
Solution Approach 1:
By utilizing three-dimensional displacement of the handling field along mutually normal directions, the patent maps complex control parameters (position, scale, rotation) to intuitive spatial movements. This dimensional mapping simplifies control operations by leveraging natural human spatial perception, reducing the cognitive load required to manage multiple display parameters simultaneously.
Solution Approach 2:
The patent combines multiple control functions into a single integrated handling field. Instead of requiring separate controls for position, scale, and rotation, all these functions are merged into one unified interface that responds to three-dimensional displacement, thereby reducing operational complexity while maintaining comprehensive control capability.
3Device complexity
If traditional two-dimensional gesture control is used, then the implementation is simple, but the ability to control three-dimensional parameters is insufficient
Solution Approach 1:
The patent extends traditional two-dimensional touch control by adding a third dimension through z-axis displacement of the handling field. This enables control of three-dimensional parameters (including layer navigation and rotation) while building upon the familiar two-dimensional interaction model, thus maintaining implementation simplicity while dramatically enhancing 3D control capability.
