Solution Overview
Problem
Current signal processing devices lack the ability to recognize and effectively utilize various input devices, such as pointers, keyboards, and remote controllers, leading to limitations in providing adaptive user interfaces and content adaptation for web applications.
Innovation Solution
A signal processing device with an input unit, storage unit, and controller that detects and activates external input devices, generating events based on connection state changes, and stores information about the devices to provide dynamic content adaptation and user interface customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the signal processing device supports multiple types of input devices, then the adaptability and versatility of the device is improved, but the device complexity increases due to the need for recognition and activation mechanisms
Solution Approach 1:
The patent implements a universal recognition mechanism that can identify multiple types of input devices (remote controllers, keyboards, pointers, gesture controllers) through a single standardized interface. The storage unit maintains information about various input device types, and the controller activates appropriate processing modes based on detected device characteristics, allowing one system to serve multiple functions without requiring separate processing paths for each device type.
2Ease of operation
If the device stores detailed information about external input devices, then the ease of operation and user interface customization is improved, but the storage requirements and system overhead increase
Solution Approach 1:
The patent stores information about input devices in a structured manner in the storage unit, maintaining specific properties for each device type (e.g., button layouts for keyboards, pointer characteristics for mice). This localized organization allows the controller to retrieve only the relevant information needed for each specific input device rather than storing and processing all possible device information uniformly, optimizing both storage efficiency and operational ease.
