Screen Projection Display With Simulated Interaction Borders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Screen projection technologies often result in incorrect operations due to the lack of clear boundaries between projected images, leading to unintended interactions with the host device's desktop or incorrect operation recognition.
Innovation Solution
The method involves determining an image display area larger than the projected image on the host device, with a simulated border area to guide user interactions, enhancing visual distinction and preventing accidental operations outside the projected image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the projected image is displayed without additional borders, then the display area is maximized, but user operations become inaccurate due to lack of visual boundaries
Solution Approach 1:
The patent divides the display area into two segments: the projected image area and the simulated border area. This segmentation provides clear visual boundaries while maintaining maximum display area utilization, resolving the contradiction between maximizing display area and ensuring operation accuracy through visual boundaries.
Solution Approach 2:
The patent introduces a simulated border area as an intermediary element between the projected image and the desktop background. This intermediary provides visual guidance and operational boundaries without occupying significant display area, enabling accurate operations while maintaining maximal image display area.
2Device complexity
If the projection window is displayed as a standard window, then the system integration is simple, but incorrect operations occur due to ambiguous boundaries
Solution Approach 1:
The patent employs color differentiation to create a simulated border area with distinct color characteristics compared to both the projected image and the desktop background. This color-based differentiation provides clear visual boundaries and operational guidance without requiring complex system modifications, maintaining simplicity while enhancing operation reliability.
3Area of stationary object
If the image display area is enlarged to fit the screen, then the visual impact is improved, but the risk of accidental operations increases
Solution Approach 1:
The simulated border area serves as a protective intermediary zone between the enlarged image display area and the desktop edges. This intermediary provides visual guidance that prevents accidental operations on the desktop while allowing the image display area to be maximized, effectively resolving the contradiction between visual impact and operational safety.

AI summary
A processing method applied to a first device includes obtaining first image information; determining an image display area based on the first image information, an size of the image display area being larger than a size of a first image corresponding to the first image information, and an area of the image display area being smaller than or equal to a first screen of the first device; and outputting a display image based on the image display area and the first image information, the display image including the first image.
