Cursor Positioning in Projection Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in accurately positioning a cursor on a setting screen with multiple images, especially when the screen is small or when multiple operable images are displayed, making it hard to determine if the cursor is correctly aligned with a desired image for image correction in projection systems.
Innovation Solution
A display control method that changes the display mode of a target image when an instruction image is located within a control region, including displaying an index image or guide images to help the user visually identify the correct image for operation, such as by altering colors, shapes, or adding auxiliary images to indicate operable positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operable images are displayed on the setting screen, then the functionality and versatility of the image correction system is improved, but the user's ability to accurately identify the cursor position and desired image deteriorates
Solution Approach 1:
The patent applies color changes by displaying the cursor in a distinct color (e.g., red) and highlighting the desired image or control region with a different color (e.g., yellow border). This visual differentiation allows users to easily identify the cursor position and target image among multiple operable images on the setting screen, resolving the contradiction between maintaining multiple functional images and enabling accurate user identification.
2Ease of operation
If the display size of the setting screen is reduced, then the portability and ease of deployment is improved, but the user's ability to check cursor alignment and image positions deteriorates
Solution Approach 1:
The patent uses color changes to provide high-contrast visual indicators on small displays. By rendering the cursor in a bright, distinct color and the control region with highlighted borders, the system maintains clear visibility and accurate position identification even when the setting screen is displayed at a reduced size, thus resolving the contradiction between deployment convenience and position verification accuracy.
3Adaptability or versatility
If the setting screen contains multiple operable images, then the comprehensiveness of image correction features is improved, but the user interface complexity and difficulty of operation increases
Solution Approach 1:
The patent simplifies user interaction with multiple correction features by using color-coded visual indicators. The cursor is displayed in a distinct color and the target control region is highlighted with contrasting colors or borders, allowing users to quickly identify operational targets without being overwhelmed by the complexity of multiple features. This reduces the cognitive load and improves ease of operation while maintaining comprehensive functionality.
