3D Contriver Tool for Dynamic Multi-Touch Modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D modeling applications on multi-touch devices do not effectively utilize multi-touch capabilities for dynamic creation and editing of 3D solid models, requiring complex gestures and muscle memory, and are not accessible to non-experts due to the need for tool selection and multiple steps.
Innovation Solution
A 3D contriver tool that allows users to create and modify 3D geometric forms using intuitive finger gestures, combining multiple concepts into a simple workflow, enabling dynamic creation and editing without tool sequencing or mode switching, and incorporating 'soft' 3D navigation that adapts to user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional 3D modeling tools are used on multi-touch devices, then modeling functionality is provided, but the operation becomes complex requiring multiple steps and tool selections
Solution Approach 1:
The patent merges multiple separate tool operations into a single integrated brush tool. Instead of requiring users to select different tools for creating, extruding, and modifying 3D forms, the system combines all these functions into one brush that automatically performs the appropriate operation based on the user's gesture and the current state of the model, eliminating the need for tool sequencing and mode switching
Solution Approach 2:
The brush tool is designed as a universal multi-functional tool that can create new 3D forms, modify existing forms, and perform various modeling operations without requiring the user to switch between different specialized tools. The tool adapts its function based on the context, providing versatility while maintaining simplicity
2Adaptability or versatility
If static creation tools are implemented for multi-touch use, then specific modeling operations are available, but the tools are detached from the 3D navigation experience and require proper selection
Solution Approach 1:
The system transitions from static creation tools that require proper selection and are detached from navigation to a dynamic brush tool that is always active and responsive. The brush dynamically adapts to the user's gestures and the current 3D view state, allowing creation and modification operations to be performed naturally during navigation without requiring the user to exit or switch modes
Solution Approach 2:
The brush tool automatically determines the appropriate operation based on the user's gesture and the current model state, eliminating the need for the user to manually select tools or configure settings. The system self-adjusts to provide the right function at the right time, making the tool autonomous and context-aware
3Productivity
If multi-touch capabilities are utilized for dynamic creation, then real-time modeling is enabled, but complex gestures and muscle memory are required
Solution Approach 1:
The system replaces complex multi-touch gesture sequences that require muscle memory with a simpler brush-based interaction model. Instead of requiring users to learn and execute precise multi-finger gestures, the brush tool responds to natural drawing-like strokes, substituting the mechanical complexity of gesture recognition with a more intuitive direct manipulation interface

AI summary
A method, apparatus, system, and computer-readable storage device is configured to perform three-dimensional (3D) modeling. A modeling tool is activated in a 3D modeling application executing on a multi-touch device. An input touch event and input gesture for creating a new 3D geometric form is received. Dynamically, in real-time as the input gesture is received, the new 3D geometric form is created and displayed. The shape of the new 3D geometric form corresponds to the input gesture.
