Voice Control Response Selection Using Wearable Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent home environments, multiple devices capable of voice control often respond simultaneously to a user's control voice, leading to chaotic scenarios due to the inability to determine which device is directly facing the user.
Innovation Solution
A method implemented by a master device that communicates with slave devices to obtain localization information based on a wearable device's location, determining the target slave device in a directly facing direction and transmitting instructions for it to respond to the control voice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple intelligent devices are provided in the home to enhance functionality and coverage, then the versatility and coverage of voice control is improved, but chaotic scenarios occur where multiple devices respond simultaneously
Solution Approach 1:
The patent introduces a master device as an intermediary that coordinates communication between the user's wearable device and multiple slave devices. The master device receives localization information from slave devices, determines which slave device is directly facing the user, and transmits instruction information only to that target slave device. This intermediary coordination mechanism prevents multiple devices from responding simultaneously while maintaining comprehensive voice control coverage.
2Measurement precision
If localization information is obtained from slave devices to determine the target device, then the accuracy of identifying the facing device is improved, but the system complexity increases
Solution Approach 1:
The master device performs multiple functions: it receives localization information from slave devices, processes this information to determine the target slave device, and transmits instruction information. By consolidating these functions in a single master device rather than requiring each slave device to independently perform localization and determination, the system achieves accurate device identification while managing complexity through functional consolidation.

AI summary
A method for responding to a control voice, a device, and a non-transitory storage medium are provided. The method is implemented by a master device that communicates with at least two slave devices located in different orientations. The localization information of at least one of the slave devices relative to a wearable device is obtained, where the location information of each of the at least one of the slave devices is obtained based on location information of the wearable device collected by the slave device through a localization component. A target slave device located in a directly facing direction of a user is determined based on the localization information, where the user is wearing the wearable device. Instruction information is transmitted to the target slave device, where the instruction information is configured to instruct the target slave device to respond to the control voice.
