Projection Display State Sync for Immersive Screen Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies fail to synchronize immersive display effects between a projecting device and a projected device, resulting in the projected device displaying content with status and navigation bars, which disrupts the immersive experience.
Innovation Solution
A method that allows the projecting device to switch between immersive and non-immersive display modes, synchronizing the display state with the projected device by sending status data to indicate hiding or displaying status and navigation bars, enabling seamless immersive display synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the projecting device hides status bar and navigation bar to implement immersive display effect, then the display quality is improved, but the projected device cannot synchronize the immersive display effect
Solution Approach 1:
The projecting device sends status data indicating the display state (immersive or non-immersive) to the projected device. The projected device receives this feedback and adjusts its display state accordingly, ensuring synchronization between the two devices. This feedback mechanism resolves the contradiction by allowing the projected device to match the immersive display effect of the projecting device.
Solution Approach 2:
Status data acts as an intermediary carrier that transmits the display state information from the projecting device to the projected device. This intermediary enables the synchronization of immersive display effects without requiring direct control or complex coordination between the devices.
2Loss of information
If the projected device displays status bar and navigation bar to show complete content, then the information completeness is improved, but the immersive display effect is disrupted
Solution Approach 1:
The display state of the projected device is dynamically adjusted based on the status data received from the projecting device. When the projecting device is in immersive mode (hiding status bar and navigation bar), the projected device also switches to immersive mode. This dynamic adjustment allows the system to maintain information completeness when needed while achieving immersive display effect when required.
3Adaptability or versatility
If the projecting device switches between immersive and non-immersive display modes, then the adaptability is improved, but the synchronization complexity increases
Solution Approach 1:
The system uses parameter changes (status data indicating display state) to manage the transition between immersive and non-immersive modes. By changing the status parameter and transmitting it to the projected device, the system achieves adaptable display mode switching while keeping the synchronization mechanism simple and manageable.

AI summary
A first electronic device displays a first interface including first content, where the first interface further includes a status bar and/or a navigation bar of the first electronic device. A second electronic device displays a first projection window including the first content, where the first projection window further includes any one of the status bar, the navigation bar, and a title bar of a projection application. The first electronic device switches from displaying the first interface to displaying a second interface, where the second interface includes second content, and the second interface does not include the status bar and the navigation bar. The second electronic device switches from displaying the first projection window to displaying a second projection window, where the second projection window includes the second content, and the second projection window does not include the status bar, the navigation bar, and the title bar.
