Voice Control Device Using Sound Volume for Target Apparatus Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In scenarios with multiple target apparatuses to be controlled by voice, there is a need to specify the target apparatus even when the user does not designate one explicitly.
Innovation Solution
A control device comprising a first receiving unit for voice operation instructions, a second receiving unit for sound volume information, a target apparatus specifying unit that identifies the target apparatus based on sound volume data, and a transmitting unit that sends operation commands to the specified apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple target apparatuses are controlled by voice without explicit user designation, then the ease of operation is improved, but the reliability of specifying the correct target apparatus deteriorates
Solution Approach 1:
The control device obtains sound volume information from each target apparatus and uses this feedback to determine which apparatus is closest to the user. This feedback mechanism enables automatic target specification without requiring explicit user designation, thereby improving ease of operation while maintaining reliability through accurate target identification based on sound volume measurements.
2Productivity
If the control device automatically specifies target apparatus based on sound volume, then the productivity is improved, but the device complexity increases
Solution Approach 1:
Each target apparatus measures its own sound volume and reports this information to the control device. The control device then automatically determines the closest apparatus based on this self-reported data, enabling automatic target specification without requiring complex additional hardware or manual intervention, thereby improving productivity while limiting the increase in device complexity.

AI summary
A control device includes a first receiving unit that receives an operation instruction given by voice or generated from voice; a second receiving unit that receives information concerning a sound volume of the voice input to a voice input unit provided corresponding to a target apparatus; a target apparatus specifying unit that specifies a target apparatus on a basis of the information concerning the sound volume received by the second receiving unit; and a transmitting unit that transmits an operation command based on the operation instruction received by the first receiving unit to the target apparatus specified by the target apparatus specifying unit.
