Voice Remote Controller Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllers with voice recognition capabilities maintain active modes for their voice recognition and communication modules even when not in use, leading to shortened battery life due to continuous power consumption.
Innovation Solution
A remote controller design that dynamically switches between stand-by and active modes based on user input and recognition of voice utterances, converting to active mode only when a voice command is given and switching back to stand-by mode if no recognition occurs within a preset time, thereby minimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the voice recognition module and communication module are kept in active mode to ensure immediate response to user input, then the responsiveness and user experience are improved, but the battery life is shortened due to continuous power consumption
Solution Approach 1:
The remote controller dynamically adjusts the operation mode of the voice recognition module and communication module between stand-by mode and active mode based on whether a user utterance is detected. This dynamic switching resolves the contradiction by ensuring immediate response when needed (active mode) while conserving battery life during normal operation (stand-by mode).
Solution Approach 2:
The system changes the operational parameters (power state) of the voice recognition module and communication module based on detection conditions. When a user utterance is detected, the modules switch from stand-by to active mode; otherwise, they remain in stand-by mode, thus optimizing both responsiveness and power consumption.
2Reliability
If the voice recognition module and communication module are kept in active mode to ensure continuous functionality, then the reliability of voice recognition is improved, but the power consumption increases and battery life decreases
Solution Approach 1:
The system periodically checks for user utterances and switches between stand-by and active modes based on these periodic detections. This periodic operation ensures that the voice recognition function remains reliable when needed while minimizing power consumption during intervals between utterances.
Solution Approach 2:
The system activates the voice recognition module and communication module only partially (when a user utterance is detected) rather than continuously. This partial action maintains sufficient reliability for voice recognition functionality while significantly reducing overall power consumption and extending battery life.

AI summary
A remote controller and a power control method are disclosed. The remote controller includes a voice recognizer a voice recognizer configured to recognize a voice utterance, a user interface configured to receive a user command; and a controller configured to, when a user command is input through the user interface to enter a voice recognition mode, convert a stand-by mode into an active mode, and convert the active mode into the stand-by mode depending on whether the utterance is recognized within a preset critical time. Accordingly, the remote controller, enabling an operation mode of a voice recognition module which recognizes a user voice utterance to be maintained as an active mode, can reduce power unnecessarily consumed.
