Cross-Device Display Control With Coordinate-Mapped Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen projection methods limit the ability of a second electronic device to display its own content and require user operation only on the first device, failing to meet specific projection needs.
Innovation Solution
A control method that establishes a connection channel between electronic devices, allowing the first device to send display data and obtain operation information, and enables coordinated display and operation of content between devices based on detected conditions and coordinate information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the second electronic device displays only the first device's content through screen projection, then the projection function is achieved, but the second device cannot display its own content and the user cannot operate the second device
Solution Approach 1:
The patent implements dynamic switching between two display modes: a first mode where the second device displays the first device's content, and a second mode where the second device displays its own content. The system dynamically transitions between these modes based on user input, allowing the second device to flexibly adapt its display function while maintaining operation control through coordinate mapping between devices
Solution Approach 2:
The second electronic device is designed to perform multiple functions: it can both display the first device's content (projection function) and display its own content (independent display function). The control system enables the second device to universally handle both projection scenarios and independent usage scenarios, eliminating the limitation of single-function display
2Adaptability or versatility
If the second electronic device displays its own content, then the display versatility is improved, but the coordinate mapping and control synchronization between devices becomes complex
Solution Approach 1:
The patent implements a feedback mechanism where the second device detects user input (such as cursor position or touch coordinates) on its display, converts these coordinates to the corresponding coordinate system of the first device, and transmits the mapped coordinates back to the first device. This feedback loop enables automatic coordinate synchronization, allowing the first device to respond to user operations on the second device without requiring complex manual coordinate mapping
Solution Approach 2:
The patent introduces a coordinate mapping mechanism as an intermediary between the two devices' coordinate systems. This intermediary layer automatically handles the transformation and conversion of coordinates between different display systems, shielding the user from the complexity of coordinate mapping while enabling seamless interaction and control synchronization between devices with different resolutions and display dimensions

AI summary
A control method includes: establishing a connection channel with a second electronic device; first condition is met, sending display data representing a first content to the second electronic device through the connection channel to cause the second electronic device to display the first content, and obtaining operation information on the first content obtained by the second electronic device through the connection channel; and if a second condition is met, displaying a second content and obtaining, through the connection channel, first coordinate information sent by the second electronic device and used to represent movement of a first target object, and displaying the first target object based on the first coordinate information, the first target object being used to operate the second content.
