Multi-Projection System Adjustment Interface Color Coding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-projection systems, users face difficulty in determining whether the image displayed is for overall or individual adjustments due to similar conditions used in both modes, leading to confusion in selecting appropriate adjustment items.
Innovation Solution
A multi-projection system with a configuration that includes a receiving section for instructions and a condition control section to differentiate the conditions of adjustment items in the item selection image between overall and individual adjustments, using color coding (black for available items and gray for unavailable items) to clearly indicate which adjustments can be made in each mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same condition is used for both overall adjustment and individual adjustment, then the adjustment interface is simple and unified, but the user cannot determine whether the image is for overall or individual adjustment
Solution Approach 1:
The patent applies local quality by making the condition of adjustment items different between overall and individual adjustments. Specifically, certain adjustment items are enabled (displayed in black) in one mode while disabled (displayed in gray) in the other mode, allowing users to locally distinguish between adjustment types without changing the entire interface structure.
Solution Approach 2:
The patent uses color changes to differentiate adjustment modes. Adjustment items that are available for selection are displayed in black, while unavailable items are displayed in gray. This color coding provides immediate visual feedback about the current adjustment mode and which items can be modified, resolving the ambiguity between overall and individual adjustments.
2Loss of information
If different conditions are used for overall and individual adjustments, then the adjustment mode can be clearly identified, but the adjustment interface becomes more complex
Solution Approach 1:
Rather than making the entire interface complex, the patent applies local quality by only modifying the condition of specific adjustment items. The differentiation is applied locally to relevant items (enabled/disabled states) while the rest of the interface remains consistent, minimizing overall complexity while achieving clear mode identification.
Solution Approach 2:
The patent uses simple color changes (black for available, gray for unavailable) rather than introducing complex visual elements. This approach provides clear mode identification through a simple, intuitive visual cue that does not significantly increase interface complexity.
3Ease of operation
If all adjustment items are always available, then the interface is simple and consistent, but users may select inappropriate adjustment items for the current mode
Solution Approach 1:
The patent applies local quality by enabling or disabling specific adjustment items based on the current adjustment mode. This ensures that only appropriate items are available for selection in each mode, preventing users from making inappropriate adjustments while keeping the interface simple through localized control changes.
Solution Approach 2:
The patent uses color changes to indicate the availability of adjustment items. Items displayed in black are available for selection, while items displayed in gray are unavailable. This provides clear visual guidance to users about which adjustments are appropriate for the current mode, improving both ease of operation and reliability.

AI summary
A multi-projection system includes a plurality of projectors and combines projection images of the plurality of projectors with each other to thereby display an image including an item selection image used to select an item to be adjusted from a plurality of adjustment items on a projection surface, a first projector as one of the plurality of projectors including a receiving section configured to receive an instruction related to an adjustment of the multi-projection system, and a condition control section configured to make a condition of the adjustment item in the item selection image different between a first case where the instruction represents a first adjustment of adjusting the plurality of projectors in a lump and a second case where the instruction represents a second adjustment of individually adjusting the plurality of projectors.
