Gesture-Based Voice Command Initiation for Silent Internet Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice command activation methods, such as using a voice recognition keyword, may not be suitable for situations like internet calls where an audible alert could interrupt the call, necessitating an inaudible method to initiate voice commands without disturbing others.
Innovation Solution
A system that uses a gesture input device and an audio input device, where the processor receives initiating and terminating gesture data to mute and unmute an internet call, allowing voice commands to be used inaudibly for controlling applications during calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a voice recognition keyword is used to activate voice commands, then voice commands can be initiated easily, but it may interrupt internet calls and disturb others
Solution Approach 1:
The patent replaces the acoustic activation method (voice keyword) with a gesture-based mechanical input method. The gesture input device detects hand gestures to activate voice commands, eliminating the need for audible keywords that would interrupt calls. This substitution allows users to initiate voice commands silently during internet calls by performing gestures in the visual field of the gesture input device.
2Speed
If the voice activation application continuously listens for keywords, then voice commands can be activated quickly, but it consumes additional energy and may detect unintended keywords
Solution Approach 1:
The system performs preliminary gesture recognition to determine user intent before activating voice command listening. Instead of continuously listening for keywords, the gesture input device first detects gestures that indicate the user wants to give voice commands. Only after this preliminary gesture detection does the system activate the voice activation application, thereby reducing unnecessary energy consumption while maintaining quick activation speed.
3Object-affected harmful factors
If a gesture input device is used to initiate voice commands, then call privacy is maintained, but the system complexity increases
Solution Approach 1:
The gesture input device is integrated into the existing computing system and serves multiple functions: it detects gestures for voice command activation, maintains call privacy by providing silent input, and can potentially detect other user intentions. This multi-functionality justifies the added complexity by providing versatile control capabilities beyond just voice command initiation.
Data Source
AI summary
In an example implementation according to aspects of the present disclosure, a system comprising a gesture input device, an audio input device, and a processor communicatively coupled to the gesture input device and the audio input device. In this example, the processor receives, by the gesture input device, initiating gesture data performed by a user which indicates an initiation of a voice command. The processor further captures, by the audio input device, the voice command spoken the user and receives, by the gesture input device, terminating gesture data performed by the user which indicates a termination of the voice command.
