Display Voice Control for Selecting Homogeneous Home Appliances
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple homogeneous home appliances, it is difficult to accurately control a specific appliance using voice commands due to ambiguity in identifying the intended device.
Innovation Solution
A display device equipped with a communication interface and processor that receives connection device information from a server, analyzes voice commands to determine the intended appliance, and transmits control commands accordingly, or displays appliance options based on the analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice commands are used to control home appliances, then ease of operation is improved, but when multiple homogeneous appliances are present, identification accuracy deteriorates
Solution Approach 1:
The patent segments the control process into two distinct phases: initial voice-based screening to identify candidate appliances, followed by secondary disambiguation through additional user input or contextual analysis. This segmentation allows the system to leverage the ease of voice commands while systematically resolving identification ambiguities among multiple homogeneous appliances.
Solution Approach 2:
The patent introduces an intermediary disambiguation mechanism that acts as a mediator between the voice command and the final appliance selection. When multiple homogeneous appliances are identified, this intermediary layer presents additional options or contextual information to the user, enabling accurate identification without requiring complex direct voice commands.
2Adaptability or versatility
If multiple homogeneous home appliances are connected, then adaptability is improved, but device identification difficulty increases
Solution Approach 1:
The patent performs preliminary actions by pre-analyzing the set of connected homogeneous appliances and organizing them into structured groups before user interaction. This preliminary organization includes identifying appliance types, locations, and characteristics, which are then presented to the user in an ordered manner that simplifies identification while maintaining support for multiple devices.
Solution Approach 2:
The patent resolves identification difficulty by adding another dimension to the selection process. Instead of relying solely on appliance type, the system introduces additional dimensions such as location, usage context, or temporal patterns to differentiate between homogeneous appliances, enabling precise identification across multiple devices.
3Productivity
If voice commands are processed automatically, then productivity is improved, but selection accuracy among homogeneous devices deteriorates
Solution Approach 1:
The patent implements periodic action by structuring the voice command processing as a multi-stage sequential process. The first stage performs rapid automatic processing to identify candidate appliances, while subsequent stages periodically engage additional verification steps or user confirmation when ambiguity is detected. This periodic engagement of disambiguation mechanisms maintains high processing speed for clear commands while ensuring accuracy for ambiguous cases.

AI summary
A display device according to as embodiment of the present disclosure may comprise: a display; a communication interface for receiving, from a first server, a connected device information set including information on each of multiple home appliances connected to the display device; and a processor for acquiring a voice signal corresponding to a voice command uttered by a user, transmitting voice data corresponding to the received voice signal and the connected device information set to a second server, receiving, from the second server, an intention analysis result for the voice command, determining, if home appliances of the same kind are included in the multiple home appliances, a home appliance matching the intention of the voice command from among the home appliances of the same kind on the basis of the received intention analysis result, and transmitting, to the first server, a control command for controlling the determined home appliance.
