Projector Automatic Configuration via NFC Position Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-projection technologies require sequential touching of projectors for configuration, which is time-consuming and inefficient for users.
Innovation Solution
Projectors obtain current position and configuration information via NFC tags, allowing them to display images based on stored configuration information without the need for sequential setup, reducing user effort and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sequential touching of projectors is used for multi-projection configuration, then the projectors can be set up to display a single image, but the user spends excessive time and effort on the setup process
Solution Approach 1:
The patent applies preliminary action by pre-storing configuration information corresponding to different installation positions in the projectors before actual use. When a projector is placed on a mounting member, it automatically reads the pre-stored configuration information associated with that position, eliminating the need for sequential manual configuration during setup.
Solution Approach 2:
The patent implements self-service by enabling projectors to automatically obtain and apply configuration information from mounting members without requiring user intervention. The projectors autonomously read position information, retrieve corresponding configuration data, and configure themselves for multi-projection display, significantly reducing user time and effort.
2Loss of time
If configuration information is pre-stored in projectors for automatic retrieval, then setup time is reduced, but the system complexity increases due to additional components like NFC tags and position information storage
Solution Approach 1:
The patent uses mounting members as intermediaries between the user and the projectors. The mounting members store position information and configuration data, acting as a mediator that automatically transfers the necessary configuration information to the projectors when they are placed on the mounting members, simplifying the overall system interaction.
Solution Approach 2:
The patent replaces the mechanical sequential touching configuration method with an automatic information retrieval system using NFC (Near Field Communication) technology. Instead of manually touching and configuring projectors in sequence, the system uses electromagnetic field-based NFC communication to automatically transfer configuration information, reducing mechanical interaction complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient display of a single image by multiple projectors with reduced user intervention, as each projector can determine and apply its configuration automatically, streamlining the projection process.
Implementation Method 1
a current position acquisition unit that tries to obtain current position information representing a current installation position of the projector; a current position judgment unit that judges whether or not obtained current position information corresponds to a position where the projector can display an image

AI summary
A display method includes, when making a plurality of projectors including a first projector project projection light to display a single image, the steps of trying, by the first projector, to obtain first position information representing the projector corresponding to an installation position of the first projector, judging, by the first projector, whether or not first multi-configuration information corresponding to the first position information is stored when the first position information is obtained, and displaying, by the first projector, a first portion of the single image based on the first multi-configuration information when it is judged that the first multi-configuration information is stored.
