Call Waiting Gesture Recognition and Audio Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience when receiving calls in quiet places, as they must either leave or ask to be excused, risking call disconnection and potential disturbance to others, while private conversations may be inadvertently leaked due to mobile phone noise.
Innovation Solution
A method that recognizes call waiting gestures on a user device, allowing users to switch to a call waiting state, stopping the speaker or microphone, and providing content like advertisements or information to keep the caller engaged until the user can move to a suitable location for the call.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user sends a text message to inform the caller they are in a meeting or driving, then the user can maintain privacy and avoid immediate call connection, but the telephone call is automatically disconnected requiring the user to call back later
Solution Approach 1:
The system performs preliminary actions by automatically sending a pre-configured text message to the caller when the user is in a meeting or driving, thereby maintaining the call connection without requiring immediate user intervention or manual message composition
Solution Approach 2:
The system provides self-service functionality by automatically managing the call state and sending notification messages without requiring user action, thereby maintaining call continuity while preserving user privacy and eliminating the need for manual call-back coordination
2Reliability
If the user answers the call in a quiet place like a conference room or library, then the user can maintain call connection, but the speaker unit noise may inconvenience others and private conversations may be leaked
Solution Approach 1:
The system extracts the audio output function from the speaker unit when the user is in a quiet place, separating the call connection maintenance from the audio playback function, thereby maintaining reliable call connection while eliminating noise disturbance to others
Solution Approach 2:
The system applies local quality control by selectively disabling the speaker unit based on the user's location context (quiet place detection), allowing call connection to be maintained while preventing noise disturbance in specific environments
3Object-affected harmful factors
If the user moves to a suitable location to receive the call, then the user can avoid disturbing others and maintain privacy, but the call may get disconnected during the move
Solution Approach 1:
The system performs preliminary action by proactively notifying the caller of the user's unavailability before the user moves to a suitable location, thereby preventing call disconnection and maintaining connection stability while enabling the user to relocate without disturbance

AI summary
The present invention relates to a method, for providing guidance during a call waiting state, comprising the steps of: a gesture recognition unit of a user device recognizing a call waiting gesture while a call request signal is being received; when the call waiting gesture is recognized, a call acceptance control unit of the user device executing a switch to a call acceptance state with respect to the call request signal received by the user device; a call waiting control unit of the user device switched to the call acceptance state stopping an operation of a speaker unit or a microphone unit of the user device and executing a switch to a call waiting state; and, if the gesture recognition unit recognizes a call switching gesture, activating the operation of the speaker unit or the microphone unit.
