Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice control systems for planetariums face delays due to changing situations, requiring a quick-responsive voice control technique that can adapt to dynamic conditions.
Innovation Solution
A control device with a storage unit, voice acquisition unit, control unit, and communication unit that determines executable commands based on projector state information, updates flags, and transmits commands to the projector, allowing for quick and accurate voice-controlled operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice control is implemented in a planetarium system, then the ease of operation is improved, but the response time may be delayed due to situation changes and command search requirements
Solution Approach 1:
The system performs preliminary actions by continuously monitoring projector state information and pre-determining which commands are executable before voice input is received. The control unit maintains an updated list of executable commands based on current projector state, so when voice input arrives, the system only needs to search among pre-identified executable commands rather than all possible commands, significantly reducing response time.
Solution Approach 2:
The system dynamically adapts the command search space based on changing projector states. As the projector state changes (different projection scenarios, time periods, or operational modes), the control unit dynamically updates which commands are marked as executable, ensuring the voice control system always operates within the contextually appropriate command set, thereby maintaining both ease of operation and quick response.
2Adaptability or versatility
If the console apparatus includes many operation items for detailed control, then the functionality is improved, but the device complexity increases making operation burdensome
Solution Approach 1:
The system extracts only the executable commands relevant to the current projector state from the complete command set. By separating executable commands from non-executable ones based on real-time state evaluation, the system presents a simplified interface to the voice control function while maintaining access to the full functionality when needed, reducing operational complexity without sacrificing adaptability.
Solution Approach 2:
The control unit serves multiple functions: it monitors projector state, determines command executability, manages the executable command list, and processes voice input. This multi-functional approach consolidates what would otherwise require separate systems into a single integrated unit, reducing overall device complexity while maintaining comprehensive control capability.

AI summary
Provided is a quick-responsive voice control technique even in use in a planetarium. A control device of a projector of a planetarium includes: a storage unit that stores a plurality of commands for controlling the projector, flags indicating whether or not the respective commands can be executed, and keywords associated with the respective commands; a voice acquisition unit that acquires voice data; a control unit that controls the control device; and a communication unit that communicates with the projector. The control unit determines whether or not each of the commands for the projector can be executed on the basis of state information of the projector, the state information being acquired through the communication unit, updates the flags on the basis of the determination result, generates character string information from voice data acquired by the voice acquisition unit, acquires a command in which an executable flag is set from the storage unit using the character string information as a search key, and transmits the acquired command to the projector.
