Voice Recognition Terminal Control in Locked State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal control methods via voice recognition require separate inputs to convert modes, limiting user convenience and allowing only limited preset commands, making it difficult to perform desired operations simultaneously.
Innovation Solution
A method and apparatus that allow voice input to control a terminal directly from a locked state by recognizing preset commands, enabling multiple operations with a single voice input and reducing power consumption by keeping only necessary components active.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is implemented in locked state, then user convenience is improved, but power consumption increases
Solution Approach 1:
The system performs preliminary voice recognition processing in the locked state before full system activation. The voice input unit and controller operate in a low-power mode to recognize wake-up commands, and only upon successful recognition does the system transition to a higher power state for full operation. This preliminary action allows the system to remain in low-power mode most of the time while still providing convenient voice-activated wake-up functionality.
2Productivity
If multiple commands are executed through single voice input, then productivity is improved, but device complexity increases
Solution Approach 1:
The system merges multiple command execution functions into a single voice input processing flow. When a wake-up command is recognized, the controller automatically executes a predefined sequence of operations including lock state release, display activation, and application launch. This merging of multiple operations into one unified voice-triggered process improves productivity by allowing users to perform multiple tasks with a single voice input, while the predefined nature of the command sequence keeps the processing logic manageable.
Solution Approach 2:
The system performs preliminary setup of command sequences during system initialization or configuration phases. Common operation sequences are pre-configured in the controller, so when voice recognition triggers a wake-up command, the system can immediately execute these pre-prepared sequences without complex real-time decision-making. This preliminary preparation reduces the complexity of on-the-fly command processing while enabling efficient multi-operation execution.

AI summary
A method for controlling a terminal through a voice input is provided. The method includes receiving a voice input when the terminal is in a state in which the terminal is locked and performing an operation corresponding to the voice input if the voice input corresponds to a preset command.
