Appliance Voice Control Activation via User Action Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-controlled personal assistants require users to speak lengthy sequences of words to control appliances, which can be cumbersome and error-prone, discouraging users due to the need for precise and fluent input.
Innovation Solution
A method where appliances detect user control actions to activate voice control systems, allowing for reduced and simplified voice input by eliminating the need for wake words and specifying appliances, enabling direct execution of commands through recognized voice inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a voice-controlled personal assistant is used to control an appliance, then the user can control the appliance remotely, but the user must speak lengthy sequences of words which increases the complexity of operation
Solution Approach 1:
The voice control process is segmented into distinct phases: wake word detection, appliance identification, and command execution. This allows the system to process information in manageable chunks rather than requiring the user to speak complete lengthy sequences, reducing the perceived complexity while maintaining functionality
Solution Approach 2:
The system performs preliminary actions by detecting wake words and identifying the target appliance before the user delivers the full command. This preliminary processing reduces the burden on the user during the actual command delivery, as the system has already prepared to receive and process the specific instruction
2Reliability
If the user speaks lengthy sequences of words to control the appliance, then the voice control system can accurately identify the command, but the user effort and time required increases
Solution Approach 1:
The system performs preliminary wake word detection and appliance identification before the user delivers the full command. This allows the system to prepare processing resources in advance, reducing the total time required for command execution while maintaining high recognition accuracy through pre-established context
Solution Approach 2:
The system dynamically adjusts its processing based on the detected wake word and identified appliance, adapting its expectations and processing focus to the specific context. This dynamic adaptation allows for faster and more accurate recognition of subsequent commands without requiring fixed lengthy input sequences
3Reliability
If the user must speak complete sequences of words including wake words and appliance names, then the system can accurately process the command, but the ease of operation decreases due to the need for precise and fluent input
Solution Approach 1:
The command structure is segmented into distinct components: wake word, appliance identifier, and action command. Each segment is processed independently with appropriate context carried forward, allowing the user to speak more naturally without requiring perfect fluency across the entire sequence while maintaining accurate command processing
Solution Approach 2:
The system introduces an intermediary processing stage between the user's wake word/appliance identification and the final command execution. This intermediary phase prepares the system to expect and accurately process the specific command, reducing the burden on the user to formulate perfect complete sentences while ensuring reliable command interpretation

AI summary
A method for controlling operation of an appliance by a user through voice control includes at least the steps of: detecting, by the appliance, a control action performed by the user on the appliance; activating a voice control system by the appliance; capturing, by the voice control system, a voice input from the user as a captured voice input; recognizing, by the voice control system, a piece of information and/or an instruction in the captured voice input from the user as a recognized information and/or instruction; and executing, by the voice control system, a user control action on the appliance in accordance with the recognized information and/or instruction.
