Multi-Modal Object Placement in Virtual Worlds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current software applications lack the ability to understand and execute multi-modal inputs, such as natural language and gestures, for complex object placement in virtual worlds, making it difficult for users to interactively manipulate graphical objects without precise instructions.
Innovation Solution
A computer system and method that utilizes multi-modal inputs like natural language, gesture, text, and sketch to manipulate graphical objects in virtual worlds, employing a Communicative Agent for Spatio-Temporal Reasoning (CoASTeR) with components like sensors, actuators, and cognitive elements to interpret and execute user commands, allowing for object placement in three-dimensional virtual environments with constraints and rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mouse-based manipulation is used for object placement, then precise control is achieved, but the operation becomes arduous and complex
Solution Approach 1:
The patent replaces the mechanical mouse-based manipulation system with a multi-modal input system that includes natural language processing, gesture recognition, and sketch processing. This substitution eliminates the need for precise mouse coordination while achieving object placement through more intuitive verbal and graphical commands.
Solution Approach 2:
The patent introduces an intermediary processing layer that includes a constraint satisfaction algorithm and a virtual agent that mediates between the user's high-level commands (natural language, gestures) and the low-level object placement operations. This intermediary translates ambiguous user intentions into precise placement actions automatically.
2Adaptability or versatility
If multi-modal inputs are accepted, then user accessibility is improved, but the system complexity increases
Solution Approach 1:
The patent implements a universal input processing framework that handles multiple input modalities (natural language, gestures, sketches, text) through a single integrated constraint satisfaction system. The same algorithmic framework processes all input types, translating them into unified placement constraints, thereby achieving versatility without proportionally increasing complexity.
3Ease of operation
If natural language commands are used, then ease of operation improves, but precision of object placement may be reduced
Solution Approach 1:
The patent incorporates feedback mechanisms where the system provides suggestions and refinements based on the natural language command. The constraint satisfaction algorithm analyzes the command, generates potential placements, and can seek clarification or confirm the intended location, thereby maintaining precision while preserving the ease of natural language interaction.
