Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current natural user interface (NUI) systems face inefficiencies in processing large amounts of input information from multiple modalities, particularly due to the limitations of late-fusion strategies that lose subtle dependencies and suffer from high computational loads and latency issues, failing to mimic human multimodal fusion effectively.
Innovation Solution
A dedicated NUI computer processor with direct, high bandwidth connectors to sensors, designed to support full processing power for simultaneous multi-modal high-resolution information handling, enabling early and intermediate fusion by synchronizing and segmenting data from various sources to reduce latency and enhance data alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If early-fusion strategy is used to process raw data from multiple sensors simultaneously, then measurement precision and reliability of user intention recognition are improved, but device complexity and computational load increase significantly
Solution Approach 1:
The patent segments the processing architecture into distinct functional modules: sensor interface layer, data synchronization layer, feature extraction layer, and fusion decision layer. Each module handles specific tasks independently, reducing overall system complexity while maintaining early-fusion benefits for preserving subtle dependencies between modalities.
Solution Approach 2:
The patent introduces intermediary components including buffer memory for temporal alignment of asynchronous sensor data, synchronization controllers for coordinate system unification, and feature selection mechanisms that filter relevant information before fusion. These intermediaries manage the complexity of simultaneous multi-modal processing.
2Device complexity
If late-fusion strategy is used to process each modality separately, then device complexity is reduced and processing becomes easier, but measurement precision and loss of subtle dependencies between modalities worsen
Solution Approach 1:
The patent performs preliminary synchronization and coordinate transformation of sensor data before separate processing. By pre-aligning temporal and spatial references of different modalities, the system maintains the ability to detect subtle dependencies even when subsequent processing stages operate semi-independently on each modality.
3Speed
If high bandwidth connectors and dedicated processing modules are used, then processing speed and latency are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent implements self-service mechanisms where the sensor interface circuitry includes integrated preprocessing capabilities that prepare data for transmission. This reduces the processing burden on the main CPU and enables faster data throughput without proportionally increasing overall system complexity.
