Screen Sharing with Image Overlay for Tracing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing technologies do not efficiently enable users to draw or embellish pictures on electronic devices by tracing images, lacking integration with other devices for enhanced drawing efficiency and convenience.
Innovation Solution
A method and electronic device that allow direct communication between devices for screen sharing, enabling users to overlay and edit images on a shared screen, creating a new screen that can be transmitted back to the other device for drawing and sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a user manually traces an image using the naked eye on a touch screen, then drawing work can be performed, but the drawing efficiency and precision are low and the process is time-consuming
Solution Approach 1:
The patent applies the copying principle by capturing an image from another electronic device and displaying it on the current device's screen as a reference. This allows the user to trace the captured image accurately without manually observing and replicating it from memory or physical reference, significantly improving drawing efficiency and reducing time consumption.
Solution Approach 2:
The patent uses another electronic device as an intermediary to provide the reference image. The first device captures and displays the image from the second device, creating an intermediary reference that facilitates accurate tracing. This intermediary approach eliminates the need for direct manual observation and improves drawing precision.
2Ease of operation
If a user downloads or installs specific applications to enable drawing functions, then drawing services can be provided, but the device complexity and operation difficulty increase
Solution Approach 1:
The patent applies universality by making the screen itself serve multiple functions - it acts as both the display for the captured reference image and the drawing surface for tracing. This eliminates the need for separate specialized drawing applications, reducing device complexity while maintaining ease of operation. The screen sharing feature provides universal access to drawing functionality across different devices.
3Adaptability or versatility
If screen sharing is implemented without image overlay capability, then device communication is simple, but drawing and embellishment functions cannot be performed
Solution Approach 1:
The patent merges the screen sharing function with the image overlay and drawing capabilities into a single integrated system. The captured image from the second device is overlaid on the first device's screen, and drawing operations on the overlaid image are synchronized back to the second device. This merging provides versatile drawing functionality while maintaining relatively simple device communication through the direct connection.
4Ease of operation
If intermediate editing steps are visible during screen sharing, then collaboration is transparent, but user convenience is reduced due to exposure of work-in-progress
Solution Approach 1:
The patent applies segmentation by separating the reference image display from the final drawing output. The captured image from the second device is displayed as a reference on the first device, allowing the user to trace without exposing their creative process. Only the final traced drawing is transmitted back to the second device, keeping intermediate editing steps private while maintaining collaboration transparency for the final result.

AI summary
A screen sharing method for an electronic device is provided. A first device communicates with a second device and shares a first screen. At the first device, a specific image is displayed superposed with the first screen, where the specific image is excluded from the first screen shared with the second electronic device. The second screen is thereafter shared with the second device. An intuitive user interface for editing a shared screen and thereafter sharing the edited screen is thus provided.
