Multi-Projector Control via Unified Touch Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen display systems with multiple projectors require cumbersome operations for image quality adjustment, as users need to individually set each projector, which is difficult and obstructs the view, especially in large settings where many people are present.
Innovation Solution
A terminal device with a touch panel screen and image capturing unit that acquires configuration information about the positional relationship of projectors, allows users to select and specify the projector for setting changes by touching the corresponding image on the screen, and transmits control signals to adjust settings such as luminance and color.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users adjust settings for each projector individually using remote controllers, then each projector can be precisely controlled, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent combines multiple projector settings into a unified control interface. The setting screen displays multiple projector images simultaneously, allowing users to select and adjust multiple projectors through a single operation rather than switching between separate remote controllers for each projector.
Solution Approach 2:
The setting terminal device provides a universal control interface that can manage multiple projectors simultaneously. This single device replaces the need for multiple individual remote controllers, enabling one device to perform the function of controlling several projectors through a unified menu system.
2Ease of operation
If IDs or menus are displayed on projectors for selection, then specific projectors can be identified and controlled, but the display obstructs the view and is unsuitable for large audiences
Solution Approach 1:
The patent extracts the selection interface from the projector display itself and relocates it to a separate setting terminal device. The terminal device displays the projector images and selection menus independently, allowing users to select projectors without any display elements obstructing the actual projector output visible to the audience.
Solution Approach 2:
The setting terminal device acts as an intermediary between the user and the projectors. It provides the selection and control interface separately from the projector displays, mediating the control process so that users can select and adjust projector settings without the interface elements appearing on the projector screens themselves.
3Measurement precision
If users must specify region and display device before adjusting settings, then precise control is achieved, but the operation becomes complex and difficult especially with many projectors
Solution Approach 1:
The patent segments the projector images into distinct selectable regions on the setting terminal device screen. Each projector image is displayed as a separate entity that can be independently selected, making it easy for users to identify and choose the specific projector they wish to adjust without complex specification steps.
Solution Approach 2:
The system performs preliminary organization of projector images on the setting terminal device before the user needs to make selections. The projector images are pre-positioned and labeled in a user-friendly layout, so when users need to select a projector, the identification work has already been done, eliminating the need for complex region and device specification sequences.

AI summary
Configuration information indicating a positional relationship for projected images of a plurality of projectors in a multi-projection realized by the plurality of projectors is acquired. An instruction on the display screen, which displays an image according to the positional relationship is accepted. Based on the configuration information and the position in the display screen of the accepted instruction, a projector for which a setting is to be changed is specified from the plurality of projectors. A signal to change the setting of the specified projector is transmitted.
