3D Animation User Interface Device for Intuitive Hand Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current user interfaces for three-dimensional animation, such as keyboards and mice, are non-intuitive and inefficient for navigating and manipulating virtual objects in 3D environments, often requiring users to input numeric values or use ambiguous 2D cursor movements, leading to difficulties in visualizing object placement and workspace clutter.
Innovation Solution
A user interface device that senses multiple user contacts, allowing intuitive navigation and object manipulation by mapping finger movements to virtual camera parameters and geometric constraints, with visual feedback and menu functions displayed based on hand geometry, enabling efficient and precise control within 3D spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user interfaces such as keyboards and mice are used for navigating and manipulating virtual objects in 3D environments, then users can perform basic operations, but the interface becomes non-intuitive and inefficient, requiring numeric value input and ambiguous 2D cursor movements
Solution Approach 1:
The patent maps 2D touchscreen gestures to 3D virtual environment operations by introducing dimensional transformation. Finger movements on the 2D screen surface are translated into 3D camera navigation and object manipulation commands, allowing users to intuitively control 3D scenes through natural 2D touch gestures without needing to understand complex numeric parameters or ambiguous cursor movements.
Solution Approach 2:
The patent introduces visual feedback elements as intermediaries between user touch input and 3D environment changes. Menu functions, geometric constraints, and camera parameter displays act as visual mediators that show users the relationship between their gestures and the resulting 3D transformations, making the interface intuitive without requiring direct understanding of complex 3D parameters.
2Measurement precision
If numeric values are used to specify object positions in 3D scenes, then precise placement can be achieved, but users lose intuitive feel of the correspondence between values and object placement
Solution Approach 1:
The patent implements visual feedback mechanisms that display camera parameters, geometric constraints, and object positions in real-time as users perform gestures. This feedback loop allows users to see the direct correspondence between their intuitive gestures and the resulting precise object placement, maintaining both precision and intuitiveness without relying on numeric value input.
3Adaptability or versatility
If graphical user interfaces with icons, menus, and toolbars are used, then comprehensive control functions are available, but the actual workspace for three-dimensional environment becomes small
Solution Approach 1:
The patent extracts control functions from traditional graphical user interface elements (icons, menus, toolbars) and integrates them directly into the 3D workspace as overlay elements. Context-sensitive menus and control options appear only when needed and in proximity to relevant objects, providing comprehensive control functionality while maximizing the visible workspace area for 3D scene manipulation.
Solution Approach 2:
The patent implements dynamic UI elements that adapt their position, size, and visibility based on user interaction context. Control functions are dynamically displayed near the user's current focus area rather than being固定在 traditional interface locations, allowing the workspace to efficiently accommodate both comprehensive control functions and large 3D environment visualization.

AI summary
A method for a computer system includes determining a plurality of positions of portions of a hand of a user simultaneously placed upon a user interface device of the computer system, retrieving a set of display icons in response to the plurality of positions of the portions of the user hand, displaying the display icons from the set of display icons on a display relative to the plurality of positions of the portions of the user hand; while displaying the display icons on the display, determining a user selection of a display icon from the display icons, and performing a function in response to the user selection of the display icon.
