Audio Remote Control Talk Button and Motion Sensor Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio responsive media devices face challenges such as reduced accuracy in wake word identification due to background noise, proximity requirements for effective command recognition, and power consumption issues from continuous listening for wake words.
Innovation Solution
An audio responsive smart remote control equipped with a speaker, microphone, and talk button, which detects the talk button press to analyze audio data for command recognition within a defined listen time period, and adjusts volume accordingly, while using a motion sensor to change volume levels based on remote control motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the media device continuously listens for wake words, then it can respond to user commands, but power consumption increases
Solution Approach 1:
The system transitions from continuous listening to periodic listening triggered by a talk button press. The remote control enters a listening state only when the user actively presses the talk button, rather than continuously monitoring for wake words. This periodic activation significantly reduces power consumption while maintaining the ability to respond to user commands when needed.
2Ease of operation
If the media device listens for wake words in environments with background noise, then it can recognize commands, but wake word identification accuracy decreases
Solution Approach 1:
The system uses audio level detection as feedback to determine when the user is speaking. When the microphone detects audio levels exceeding a threshold, the system activates the listening state. This feedback mechanism allows the system to distinguish between background noise and actual user speech, improving wake word identification accuracy by only processing audio during relevant time windows.
3Device complexity
If users must be located close to the media device for commands to be heard, then audio processing is simpler, but user experience flexibility is reduced
Solution Approach 1:
The remote control acts as an intermediary device between the user and the media device. The remote control includes its own microphone and processing capabilities, allowing it to capture and process audio commands independently of the media device's location. This intermediary approach enables users to issue commands from a distance while the remote control handles the audio processing tasks.

AI summary
Disclosed herein is an audio responsive remote control for controlling a media device. The remote control includes at least a speaker and microphone. The remote control is configured to: detect the talk button being pressed; responsive to the detection and within a time period that commences from the detection, analyze received audio data received to recognize one or more audio commands; and process the recognized audio commands. The remote control is also configured to: determine a volume level of the received audio data; and audibly confirm the recognized audio commands at the determined volume level. According to some embodiments, the remote control also includes a motion sensor, and is configured to: detect motion of the remote control using the motion sensor; determine that the detected motion corresponds to a volume changing motion; and adjust volume of the remote control and/or a media device according to the volume changing motion.
