Device-State Screen Projection Switching to Reduce Manual Operations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent manual operations required for switching screen projection windows between electronic devices, such as a mobile phone and a tablet computer, disrupt user experience and increase power consumption.
Innovation Solution
A method where electronic devices automatically adjust screen projection based on changes in their physical state, such as being placed on a holder or held by a user, allowing the display of one device to serve as an extension screen of another without displaying a projection window, and enabling seamless switching without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually switches the screen projection window between electronic devices, then the projection window can be displayed on the desired device, but the user experience is degraded due to frequent manual operations
Solution Approach 1:
The system automatically detects device status changes (such as when a device is placed on a holder or held by a user) and autonomously switches the screen projection window without requiring manual user intervention. The projection source device monitors status changes and automatically adjusts projection settings, enabling the system to serve itself rather than requiring continuous user control.
Solution Approach 2:
The system continuously monitors the status of electronic devices (whether they are being held or placed on a holder) and uses this feedback information to automatically adjust the screen projection window. When a status change is detected, the system receives feedback about the new state and automatically switches the projection accordingly, creating a closed-loop control system that responds to real-time conditions.
2Use of energy by moving object
If the screen projection window is displayed on the electronic device, then the projected content is visible, but power consumption increases
Solution Approach 1:
Instead of continuously maintaining screen projection, the system adopts a periodic action approach by monitoring device status changes and only activating projection when necessary. The projection is suspended when devices are placed on holders or not in use, and only activated when devices are picked up or status changes indicate projection is needed, thereby reducing overall power consumption while maintaining projection availability when required.
3Ease of operation
If the screen projection window is minimized to avoid blocking content, then the tablet computer can be used without obstruction, but the user must perform frequent switching operations
Solution Approach 1:
The system automatically manages the display space by monitoring device status changes and autonomously switching the screen projection window between minimized and full display states without user intervention. When a device is placed on a holder, the system self-adjusts to minimize the projection window to avoid blocking content. When the device is picked up or status changes, the system automatically restores the projection window, eliminating the need for manual switching operations.

AI summary
The present disclosure relates to window switching methods and electronic devices. One example method is applied to a first electronic device and a second electronic device. The first electronic device and the second electronic device have a screen projection relationship. When it is determined that the first electronic device or the second electronic device has switched from a first state to a second state, the first electronic device may display a first display interface and suspend screen projection to the second electronic device. The second electronic device displays a first icon, where the first icon indicates that a display of the first electronic device serves as an extension screen of the second electronic device.
