Projector Shape Correction Control Point Selection Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector technologies lack user convenience in shape correction operations, as it is unclear which correction point will be selected when using arrow keys or similar controls, making it difficult for users to efficiently change the selected correction point.
Innovation Solution
A method and system that displays a control point image representing multiple control points for shape correction, with a first image indicating the selected control point and a second image showing adjacent control points, allowing users to easily select subsequent control points through directional input, enhancing user interaction and clarity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If arrow keys or similar controls are used to change the selected correction point, then the user can navigate through control points, but it is unclear what correction point will be selected next, reducing user convenience
Solution Approach 1:
The system performs preliminary action by displaying a preview indicator that shows which control point will be selected next before the user actually selects it. This allows users to anticipate the selection outcome and make informed navigation decisions, resolving the uncertainty about next control point selection while maintaining ease of operation with arrow keys
Solution Approach 2:
The system implements feedback by providing visual information about the next selectable control point through a preview indicator. This feedback mechanism informs users about the consequence of their navigation input, enabling them to adjust their selection strategy and improving overall user convenience in the shape correction process
2Adaptability or versatility
If multiple control points are displayed for shape correction, then comprehensive correction capability is provided, but it becomes difficult for users to identify and select the appropriate control point
Solution Approach 1:
The system applies local quality by differentiating the visual appearance of control points based on their selection state. The currently selected control point is displayed with distinct visual characteristics (such as highlighting or color changes), while other control points have different appearance. This allows users to easily identify the active control point among multiple control points, maintaining comprehensive shape correction capability while improving selection ease
Solution Approach 2:
The system uses color changes to indicate the selected control point among multiple control points. By changing the color or brightness of the selected control point marker, users can quickly identify which control point is active for editing, making it easier to operate with multiple control points available for shape correction

AI summary
A method of displaying an image includes displaying an initial pattern image representing two or more control points to be used for shape correction of a projection image of a projector, displaying a first image representing that a first control point as one of the two or more control points is selected, at a position of the first control point such as a first position, when the first control point is selected, and displaying a second image representing the two or more control points to be selected by a user subsequently to the first control point out of the two or more control points, when displaying the first image at the position of the first control point such as the first position.
