Display Apparatus Voice Control via Pointing Signal Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses require users to move to a search screen or convert modes to perform control operations using voice recognition, which is inconvenient for selecting content and searching information.
Innovation Solution
A display apparatus and method that allows control based on pointing signals, user motion, and voice recognition without the need to move to a search screen, using a processor to extract keywords from selected items and perform control operations through a remote control apparatus, enabling simultaneous voice and gesture recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display apparatus uses voice recognition mode to perform control operations, then the user can control the apparatus without moving to a search screen, but the user cannot simultaneously select content using pointing signals
Solution Approach 1:
The system dynamically switches between pointing signal control mode and voice recognition mode based on the current operational context. When an item is selected via pointing signal, the system automatically transitions to voice recognition mode, allowing the user to issue voice commands without manually changing modes. This dynamic adaptation resolves the contradiction by making the control system flexible enough to handle both pointing and voice inputs appropriately.
Solution Approach 2:
The display apparatus is designed to support multiple control modes (pointing signals and voice recognition) within a single unified system. The controller can process both types of inputs and switch between them seamlessly, making the apparatus universally controllable through different methods without requiring separate dedicated modes or screens.
2Reliability
If the display apparatus requires mode conversion to perform voice recognition, then the system maintains clear operational boundaries, but the user interaction becomes more complex
Solution Approach 1:
The system performs preliminary detection of the current operational state (whether an item is selected via pointing signal) and automatically prepares the appropriate control mode in advance. When an item is selected, the system proactively switches to voice recognition mode before the user needs to issue a voice command, eliminating the need for manual mode conversion and simplifying user interaction while maintaining operational reliability.
Solution Approach 2:
The system provides feedback about the current control mode based on the detected operational context. When an item is selected through pointing signals, the system automatically transitions to voice recognition mode, informing the user through the system's response behavior that voice commands are now accepted. This feedback mechanism maintains operational clarity while reducing the complexity of manual mode switching.
3Productivity
If the display apparatus processes both pointing signals and voice commands simultaneously, then the user can seamlessly control and search content, but the system complexity increases
Solution Approach 1:
The control system is segmented into distinct functional modules: a pointing signal processing module, a voice recognition module, and a controller that coordinates between them. The controller detects the current operational state and routes appropriate input types to the corresponding processing module. This segmentation allows the system to handle both pointing signals and voice commands efficiently while managing complexity through modular architecture.

AI summary
A display apparatus includes a display which displays a plurality of items, a communicator which receives a pointing signal from a remote control apparatus, an input device which receives at least one of a voice command and a gesture, and a processor which selects one item among the plurality of items based on at least one of the pointing signal and the gesture, and in response to receiving the voice command regarding the selected item, perform a control operation based on a keyword extracted to execute the received voice command.
