Display Interaction Mapping for Full-Screen Second-Device Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen projection technologies fail to utilize the full display area of a second device, limiting user interaction and experience.
Innovation Solution
A display interaction system that maps the interface of a first device onto a second device, allowing for a larger display area and user interface customization, including full-screen and multi-window options based on the second device's capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If screen projection is performed using existing technology, then content can be shared between devices, but the display area of the second device is not fully utilized
Solution Approach 1:
The patent changes the display parameters by detecting the second device's screen resolution and aspect ratio, then dynamically adjusting the projection interface's layout, window size, and content arrangement to match the target display characteristics, thereby fully utilizing the second device's display area
Solution Approach 2:
The system implements dynamic interface adaptation where the projection layout is not fixed but dynamically adjusts based on the detected characteristics of the second device, allowing the interface to transform and reconfigure itself to fit different screen sizes and resolutions
2Area of stationary object
If the window size is kept unchanged during projection, then the original interface layout is preserved, but the display area of the second device fails to be fully used
Solution Approach 1:
The patent applies local quality by making different parts of the interface adaptable - critical elements maintain their functional characteristics while non-critical elements (margins, spacing, less important content) are adjusted to fill the available display area, achieving both area utilization and layout stability
3Ease of operation
If the interface is mapped directly without adaptation, then implementation is simple, but user interaction experience on large screens is limited
Solution Approach 1:
The system implements self-service by automatically detecting the second device's screen characteristics and autonomously adjusting the projection interface without requiring manual user configuration, thereby improving user experience while keeping the interaction simple and the adaptation process transparent

AI summary
The display interaction system includes a first device and a second device. The first device is configured to send interface display information of a first application to the second device. A first user interface of the first application is displayed on a display of the first device. The interface display information includes data used by the first device to display the first user interface. The second device is configured to display a second user interface of the first application based on the interface display information. Content displayed in the second user interface includes content displayed in the first user interface, a layout of the second user interface is different from a layout of the first user interface, and a display area of the second user interface is larger than a display area of the first user interface.
