Projector Mode Switching With Automatic Device Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors require manual mode switching by users, which can be cumbersome, especially for those unfamiliar with the operation, and lack automatic mode adaptation based on connected devices.
Innovation Solution
A projector system that automatically switches operation modes based on application information detected from connected information processing devices, either processing operation information internally or transmitting it to the device, through data communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual mode switching is implemented, then the projector can support multiple operation modes (PJ interactive and PC interactive), but the user operation becomes complicated and troublesome
Solution Approach 1:
The projector automatically detects the connected information processing device and switches operation modes without user intervention. The system acquires device information through the coupler, identifies the device type, and autonomously selects the appropriate mode (PJ interactive or PC interactive), making the system self-configuring and eliminating manual mode selection
Solution Approach 2:
The projector establishes a feedback loop by continuously monitoring the connected device through the coupler, acquiring device information, and adjusting the operation mode based on the detected device type. This closed-loop system automatically adapts to the connected device, providing responsive and context-aware mode switching
2Reliability
If manual mode switching is required, then the projector maintains clear mode definitions, but users unfamiliar with operations find it difficult to switch modes
Solution Approach 1:
The projector performs automatic device identification and mode selection without requiring user knowledge or intervention. By acquiring device information through the coupler and autonomously determining the appropriate mode, the system eliminates the need for users to understand or manually switch between operation modes
3Ease of operation
If automatic mode switching based on device detection is implemented, then user convenience is improved, but the device complexity increases
Solution Approach 1:
The coupler serves multiple functions: it detects device connection, acquires device information, identifies device type, and triggers mode switching. By making the coupler a multi-functional component, the patent avoids adding separate dedicated components for each function, thereby limiting the increase in overall device complexity

AI summary
A projector 100 acquires application information for identifying a coupling APP 245 that operates in an information processing device 200 from the information processing device 200, and switches, based on the acquired application information, an operation mode of the projector 100 to a PJ interactive mode in which operation information of an operation received by the projector 100 is processed by the projector or a PC interactive mode in which the operation information is transmitted to the information processing device 200 via a data communication line.
