Hands-Free Call Forwarding via Gesture Detection and NFC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in forwarding calls between fixed and portable terminals, as they need to manually press a call forwarding button, especially when hands are busy, and there is a need for a hands-free solution.
Innovation Solution
Implementing a method and apparatus that enables call forwarding through near field communication between fixed and portable terminals, allowing users to perform specified operations to automatically forward calls without directly pressing buttons, using sensors and communication modules to detect proximity and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user manually presses a call forwarding button on a fixed terminal, then call forwarding function is activated, but user convenience deteriorates when hands are busy
Solution Approach 1:
The portable terminal automatically initiates call forwarding requests based on sensor-detected user actions (shaking, knocking) without requiring manual button pressing. The system serves itself by interpreting physical gestures as command inputs, eliminating the need for complex manual operation procedures.
Solution Approach 2:
The patent replaces the mechanical button-pressing interface with sensor-based detection of physical gestures (shaking, knocking). The sensor unit detects movements and the control unit translates these mechanical gestures into electronic call forwarding commands, substituting the traditional mechanical interaction paradigm.
2Ease of operation
If call forwarding is implemented through near field communication between terminals, then user convenience is improved, but device complexity increases
Solution Approach 1:
The portable terminal integrates multiple functions into a single device: it acts as both the gesture-detecting controller and the NFC communication initiator. The fixed terminal similarly combines call handling and NFC reception functions, reducing the need for separate dedicated devices and simplifying the overall system architecture.
Solution Approach 2:
The NFC communication serves as an intermediary mechanism between the portable terminal's gesture detection and the fixed terminal's call forwarding function. This standardized communication protocol enables seamless interaction between devices without requiring complex custom integration, acting as a universal mediator for data exchange.
3Ease of operation
If manual button pressing is required for call forwarding, then system reliability is maintained, but ease of operation deteriorates in hands-busy scenarios
Solution Approach 1:
The system pre-associates specific gesture patterns (shaking, knocking) with call forwarding commands during setup. When these pre-defined gestures are detected, the corresponding action is automatically triggered without requiring real-time interpretation or confirmation, ensuring both ease of execution and operational reliability.
Solution Approach 2:
The sensor unit continuously monitors for gesture inputs and provides immediate feedback to the control unit, which then executes the call forwarding command. This real-time feedback loop ensures that the system responds reliably to user intentions while maintaining simple gesture-based operation, bridging the gap between ease of use and operational reliability.

AI summary
According to one embodiment, a method for performing a user call forwarding operation through near field communication between a fixed terminal and a portable terminal includes determining that a distance between a first fixed terminal and the portable terminal is within a specified distance, detecting a movement within the specified distance, determining that the detected movement is the same as a specified movement, and requesting call forwarding to the first fixed terminal when the detected movement is the same as the specified movement.
