Intelligent Voice System for Projector Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent voice systems do not provide a means for users to control projectors using voice commands, lacking the necessary technical solutions for integrating projector control into voice-assisted environments.
Innovation Solution
An intelligent voice system comprising a voice assistant, a cloud service platform, a projector, and a management server, where the voice assistant extracts keywords from voice signals, the cloud service platform analyzes and generates corresponding control commands, and the management server adjusts the projector's operating state accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional remote control interface is used for projector control, then the control method is familiar to users, but the operation convenience and intuitiveness are insufficient
Solution Approach 1:
The patent replaces the mechanical remote control interface with a voice-based control system. The voice assistant receives voice signals, extracts keywords, and converts them into control commands, eliminating the need for physical remote control operations and significantly improving ease of operation.
Solution Approach 2:
The patent introduces a cloud service platform as an intermediary between the voice assistant and the projector management system. This intermediary handles semantic analysis, keyword extraction, and command generation, allowing the system to remain modular while achieving voice control functionality.
2Ease of operation
If voice control functionality is added to the projector system, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal control architecture where the cloud service platform can manage multiple projectors and various intelligent devices. The management server handles device registration, authentication, and command routing, creating a multi-functional system that can control different devices through a unified voice interface.
Solution Approach 2:
The cloud service platform acts as an intermediary that handles the complex tasks of semantic analysis, keyword extraction, and command generation. This allows the voice assistant and projector to remain relatively simple while the intermediary handles the complexity of integrating voice control with projector operations.
3Productivity
If manual control operations are required for projector functions, then the system structure remains simple, but the productivity and work execution efficiency are reduced
Solution Approach 1:
The patent implements a self-service control system where the voice assistant automatically processes user commands, extracts relevant keywords, and generates appropriate control commands without requiring manual intervention. The system autonomously manages the control workflow from voice input to projector action, significantly improving productivity.
4Adaptability or versatility
If existing voice assistant systems are used without projector integration, then the system complexity is low, but the adaptability and functionality are limited
Solution Approach 1:
The patent creates a universal control system where the cloud service platform and management server can handle multiple projector devices and various control functions. The system is designed to be extensible, allowing it to adapt to different projector models and additional intelligent devices while maintaining a consistent voice control interface.

AI summary
The disclosure provides an intelligent voice system and a method for controlling a projector. The system includes a voice assistant, a cloud service platform, a projector, and a management server. When the voice assistant receives a voice signal for controlling the projector, the voice assistant extracts keywords from the voice signal and transmits the keywords to the cloud service platform, wherein the keywords include an alias corresponding to the projector and a first control command, and the cloud service platform includes second control commands. The cloud service platform analyzes the first control command, retrieves the corresponding second control command according to the first control command, and transmits the alias of the projector and the corresponding second control command to the management server. The management server accesses/controls the projector in response to the alias and adjusts the projector as a first operating state according to the corresponding second control command.
