Solution Overview
Problem
Electronic apparatuses with input devices, such as keyboards, face performance issues when users are unfamiliar with the keyboard, due to varying trigger sensitivity and operation habits, leading to suboptimal input signal processing.
Innovation Solution
A control method that detects the presence and execution of a setup program, generates control signals based on user instructions and adjusting information, and processes input signals to delay and optimize trigger sensitivity, providing customizable delay settings and user interfaces for selecting control modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the keyboard trigger sensitivity is fixed according to manufacturer specifications, then the device complexity is reduced, but the adaptability to different user operation habits and keyboard performances deteriorates
Solution Approach 1:
The patent applies preliminary action by detecting keyboard trigger sensitivity before normal input processing begins. A setup program is executed beforehand to measure the actual trigger sensitivity of the specific keyboard hardware, and this measured value is stored for subsequent use. This preliminary detection allows the system to adapt to different keyboards without requiring complex real-time adjustments during normal operation.
Solution Approach 2:
The patent introduces an intermediary component - a setup program acting as a mediator between the user input system and the electronic apparatus control system. This intermediary program performs the sensitive detection, calculates appropriate delay parameters, and configures the system accordingly before normal operation. It serves as a bridge that translates physical keyboard characteristics into software-controlled delay parameters.
2Measurement precision
If the input signal processing is performed without delay adjustment, then the processing speed is maintained, but the input accuracy for unfamiliar keyboards deteriorates
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the delay parameter based on the detected keyboard trigger sensitivity. The system measures the actual trigger sensitivity of the keyboard and calculates an optimal delay value that compensates for variations in keyboard response characteristics. This parameter adjustment occurs in the time domain, modifying when the input signal is processed relative to when it is generated.
3Adaptability or versatility
If a setup program is always executed to detect keyboard characteristics, then the adaptability to different keyboards is improved, but the operation time and user convenience deteriorate
Solution Approach 1:
The setup program performs keyboard sensitivity detection as a preliminary action during system initialization or first boot, before normal operation begins. The detected characteristics are stored and reused for subsequent operations, avoiding repeated detection processes. This ensures keyboard compatibility is established upfront without impacting ongoing system performance.
Solution Approach 2:
The system performs self-service by automatically detecting keyboard trigger sensitivity and configuring appropriate delay parameters without requiring manual user intervention. The setup program autonomously measures the keyboard characteristics, calculates optimal settings, and applies the configuration, eliminating the need for users to manually adjust parameters or understand technical details.
