EM Sensing Circuit for Automatic Target Device Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice command systems require users to specify a target device for operation, leading to user inconvenience and delayed operations when the device is not specified in the utterance, as additional input or guidance is needed to identify the target device.
Innovation Solution
An electronic device equipped with a microphone, communication circuit, and EM sensing circuit that transmits EM signals to a server to identify and specify a target device, allowing voice commands to be executed without explicit device specification by using a processor to receive EM signal information, determine the target device, and control it based on voice inputs and path rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user is required to specify a target device through additional utterance or input, then the target device can be identified, but the convenience of the user deteriorates and operation of the target device is delayed
Solution Approach 1:
The electronic device performs preliminary actions by proactively sensing EM signals from external devices and pre-specifying target devices before the user issues a voice command. The processor receives EM signals through the EM sensing circuit, identifies external devices, and prepares target device specifications in advance, so when the user speaks, the system can immediately execute the command without requiring additional device specification input.
Solution Approach 2:
The system performs self-service by automatically identifying and specifying the target device using EM signal sensing without requiring user intervention. The processor autonomously analyzes EM signals, determines which external device should be the target, and completes the device specification process automatically, freeing the user from the burden of manually specifying devices.

The processor receives EM signals through the EM sensing circuit, identifies external devices, and prepares target device specifications in advance, so when the user speaks, the system can immediately execute the command without requiring additional device specification input.
Solution Approach 2:
The system skips the time-consuming step of requesting additional user input for device specification. By using EM signal sensing to automatically identify and specify the target device, the system rushes through the identification process in the background, eliminating the waiting time that would otherwise be required for user interaction.
3Ease of operation
If EM signal sensing is used to automatically specify the target device, then user convenience is improved and operation speed is increased, but the device complexity increases
Solution Approach 1:
The EM sensing circuit acts as an intermediary component that bridges the gap between the user's voice command and the target device identification. Rather than requiring complex user input processing or device selection interfaces, the EM sensing circuit provides a straightforward physical signal that the processor can easily interpret to automatically identify the target device, simplifying the overall control flow.
