Proximity Input for 3D Virtual Layer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch screen technologies and 3D displays face challenges in providing intuitive and efficient user interaction methods, especially in controlling virtual layers in a stereoscopic environment, as they often require direct contact or complex gestures, limiting the user's ability to interact with 3D graphical user interfaces effectively.
Innovation Solution
The implementation of a proximity detection system that allows users to control virtual layers through hovering inputs, using capacitive or other proximity detection techniques to detect the position and movement of input objects relative to the screen, enabling manipulation of 3D display views without direct contact, and associating specific gestures or movements with various actions such as selection, zooming, or layer manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct contact with touch screen is used for user input, then input detection is reliable, but user interaction becomes less intuitive for 3D interfaces
Solution Approach 1:
The patent extends the interaction space from 2D touch screen surface to 3D space above the screen by detecting hovering inputs at different heights. This allows users to interact with virtual layers in a stereoscopic environment using natural hand movements in three-dimensional space, making the interaction more intuitive while maintaining reliable detection through capacitive sensing technology.
Solution Approach 2:
The patent introduces virtual layers as an intermediary between the user and the 3D graphical user interface. These virtual layers are positioned at different depths in the stereoscopic display and can be manipulated through hovering inputs, providing a natural interface for 3D interaction while the capacitive detection system ensures reliable input detection.
2Measurement precision
If complex gestures are required for 3D interface control, then precise manipulation is achieved, but user operation becomes complicated
Solution Approach 1:
The patent enables precise manipulation of virtual layers by detecting partial hovering actions at different heights above the touch screen. Users can perform simple hovering movements to select, move, or manipulate interface elements without requiring complex gesture sequences, achieving precise control through simplified partial actions.
Solution Approach 2:
The patent implements dynamic virtual layers that respond to hovering inputs in real-time. The virtual layers can be positioned, resized, and manipulated based on the user's hand movements in 3D space, providing intuitive and responsive interaction that adapts to user actions without requiring pre-defined complex gestures.
3Adaptability or versatility
If multiple virtual layers are displayed in 3D space, then interface functionality is enhanced, but detection of hovering inputs becomes more difficult
Solution Approach 1:
The patent segments the touch screen into multiple detection zones corresponding to different virtual layers positioned at various heights in 3D space. Each zone can independently detect hovering inputs, allowing the system to determine which virtual layer the user intends to interact with based on the height and position of the hovering object, thus managing complex multi-layer detection through spatial segmentation.
Solution Approach 2:
The patent replaces complex mechanical or optical 3D input detection systems with capacitive sensing technology. The capacitive sensor array can detect changes in electrical field caused by hovering conductive objects (such as fingers or stylus) at different heights, providing accurate 3D hovering input detection without requiring complex mechanical or optical mechanisms.
