Projector Connection via Server-Mediated Identification Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connection methods between projection devices and information processing devices via wireless communication are cumbersome for users, particularly when using devices placed on a desk or connected in a wired manner, as they require manual image capture and wired connections, which can be burdensome.
Innovation Solution
A method involving a projection device displaying a first identification code, a second information processing device capturing and associating this code with identification information, and a third device transmitting this information to connect to the projection device, reducing user effort by allowing image capture and connection through a handheld terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired connection and manual image capture are used to connect projection device and information processing device, then connection reliability is improved, but user operation burden increases
Solution Approach 1:
A server acts as an intermediary between the projection device and the information processing device. The server receives identification information from the projection device, stores it, and transmits it to the information processing device, enabling wireless connection without manual image capture or wired connections
Solution Approach 2:
The projection device automatically transmits its identification information to the server, and the server automatically transmits this information to the information processing device. The system performs connection setup automatically without requiring manual user intervention for image capture or wired connection
2Stability of the object's composition
If manual image capture and wired connection are required, then connection stability is improved, but connection time increases
Solution Approach 1:
The projection device transmits its identification information to the server in advance before the information processing device needs to connect. The server stores this identification information and prepares it for transmission to the information processing device, so that when connection is needed, the information is already ready and can be transmitted immediately
Solution Approach 2:
The patent replaces manual mechanical operations (wired connection, manual image capture) with automated wireless communication. The server automatically handles identification information transmission between devices, eliminating the need for manual user actions and reducing connection time
3Device complexity
If front camera is used for image capture, then device simplicity is maintained, but ease of operation deteriorates
Solution Approach 1:
The server serves as an intermediary that receives identification information from the projection device and transmits it to the information processing device. This eliminates the need for the information processing device to use its front camera for image capture, as the server handles the identification information transmission instead
