Display System Voice Control Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice operation systems for display devices require multiple network communications between smart speakers and servers for each user operation, leading to delays in executing user requests.
Innovation Solution
A display system with a voice processing device that generates voice data for both first-type and second-type operations, where the display device includes a voice recognition unit to recognize second-type operations without server intervention, allowing direct execution by a control unit based on server-permitted commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display device communicates with the server device for every operation, then the system maintains centralized control and security, but the operation response time increases due to multiple network communications
Solution Approach 1:
The patent segments operations into two types: first-type operations that require server communication and second-type operations that can be executed locally. The control unit is divided into a voice recognition unit for local processing and a control unit for execution, separating functions that need server validation from those that can respond immediately
Solution Approach 2:
The system performs preliminary action by obtaining server permission in advance for second-type operations. Once permission is granted, the display device can execute these operations locally without further server communication, preparing the system ahead of time to enable faster subsequent responses
2Productivity
If the display device executes operations locally without server communication, then the operation speed increases, but the system loses centralized control and security management
Solution Approach 1:
The server acts as an intermediary that provides permission for local execution. The control unit mediates between local voice recognition and server authorization, allowing fast local execution while maintaining server oversight through the permission-granting mechanism
Solution Approach 2:
The system performs preliminary action by obtaining server permission in advance for second-type operations. Once permission is granted, the display device can execute these operations locally without further server communication, preparing the system ahead of time to enable faster subsequent responses while maintaining security
3Reliability
If the system requires server-mediated communication for all operations, then security and authorization are maintained, but the operational efficiency and user experience deteriorate
Solution Approach 1:
The patent segments operations into first-type operations requiring server communication and second-type operations executable locally with pre-obtained permission. This segmentation maintains security for important operations while enabling efficient local execution for routine tasks
Solution Approach 2:
The system dynamically adjusts its communication behavior based on operation type. For second-type operations, it transitions from continuous server communication to local execution with pre-granted permission, optimizing performance while maintaining security architecture

AI summary
A control method for a display system is provided. The display system includes a display device displaying an image, and a voice processing device which generates first voice data based on a first voice requesting a first-type operation belonging to a part of a plurality of types of operations to the display device and transmits the first voice data to a server device. The display device receives a command to execute the first-type operation from the server device. The display device includes a voice recognition unit recognizing a second voice requesting a second-type operation that is different from the first-type operation, and a control unit controlling execution of the first-type operation and the second-type operation. The voice processing device transmits the first voice data requesting a permission for the execution of the second-type operation, to the server device. The display device receives a command permitting the execution of the second-type operation from the server device. The control unit starts the execution of the second-type operation in response to the command permitting the execution of the second-type operation.
