Problem

Current wireless screen projection technologies lack flexibility in collaborative display between terminals with different sizes, resulting in limited and inflexible visual experiences.

Innovation Solution

A method for displaying different parts of an application interface on multiple terminals, allowing flexible and rich collaborative display by detecting proximity or user operations, and synchronizing content between terminals using shared memory data objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screen content is projected from mobile phone to large-screen device using current wireless screen projection technology, then the large-screen device can display the content, but the display manner is single and flexibility is poor

Engineering Contradiction:
Improvecollaborative display flexibilityVSAvoiddisplay system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The application interface is segmented into multiple parts (first part and second part), where the first terminal displays the first part and the second terminal displays the second part. This segmentation enables flexible collaborative display across different terminals while maintaining system simplicity through clear division of display responsibilities.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If different terminals with different display sizes are used for collaboration, then visual effects can be improved, but the current technologies lack flexibility in achieving this

Engineering Contradiction:
Improvemulti-terminal display adaptabilityVSAvoidoperational simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

Different parts of the application interface are assigned to different terminals based on their display characteristics. The first terminal with its display size and capabilities renders the first part, while the second terminal renders the second part. This local quality assignment optimizes visual effects for each terminal's specific characteristics while maintaining ease of operation through automated partitioning.

Inventive Principle:
Principle #3Local quality

3Productivity

If the first terminal displays both parts of the interface, then the interface is complete, but the collaborative display capability is not utilized

Engineering Contradiction:
Improveinterface display efficiencyVSAvoiddistributed display capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The display system transitions from a single-terminal two-dimensional display to a multi-terminal distributed display architecture. The interface is partitioned such that the first terminal displays the first part and the second terminal displays the second part, utilizing the additional dimension of spatial distribution across multiple devices to enhance both productivity and adaptability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A distributed display method and terminal for an application interface are provided, and relate to the terminal field. Different parts of an application interface are collaboratively displayed on a plurality of terminals, so that manners for collaborative display between the plurality of terminals are more flexible and richer. The method includes: A first terminal displays a first interface, where the first interface includes a first part and a second part. When the first terminal detects that a preset condition is met, the first terminal displays a second interface, where the second interface includes the first part and does not include the second part; and the first terminal notifies a second terminal to display a third interface, where the third interface includes the second part and does not include the first part.
