Solution Overview
Problem
Existing screen sharing technologies between electronic devices limit user interaction to single operations, affecting user experience.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the recipient device receives only single operations on the shared screen, then the system complexity is low, but the user interaction quality deteriorates
Solution Approach 1:
The patent segments user operations into distinct event types (single-tap, double-tap, touch-and-hold, flicking) with specific event information including event type identification and operation area coordinates. This segmentation allows the system to process complex interactions through structured, modular event categories rather than treating all operations as uniform actions.
Solution Approach 2:
The patent adds a new dimension to screen sharing by enabling bidirectional interconnection mode where the recipient device can send operations back to the initiator device. This transforms the traditional unidirectional screen sharing into a multi-dimensional interaction system with feedback loops, allowing operations to flow in both directions between devices.
2Ease of operation
If the recipient device enables interconnection mode to detect multiple operations, then the user interaction quality improves, but the device complexity increases
Solution Approach 1:
The patent implements an interconnection mode that enables the recipient device to perform multiple functions: detecting various operation types, determining event information, enabling/disabling interconnection, and sending operations to the initiator device. This multi-functionality consolidates diverse interaction capabilities into a unified mode, managing complexity through functional integration rather than separate mechanisms.
Solution Approach 2:
The interconnection mode is dynamically enabled or disabled based on user needs. The system transitions between states (connected/disconnected) allowing flexible control over the level of interaction complexity. This dynamic approach lets users activate enhanced interaction capabilities only when needed, reducing perceived complexity during standard operations.
3Adaptability or versatility
If the system supports multiple operation types, then the adaptability improves, but the ease of operation deteriorates due to increased complexity
Solution Approach 1:
The patent applies local quality by associating specific event types with specific operation areas on the screen. Each operation generates event information containing both the event type (single-tap, double-tap, etc.) and the precise operation area coordinates. This localized approach allows the system to handle diverse operations through a consistent event structure, maintaining simplicity while supporting versatility.

AI summary
An enhanced screen sharing method includes: a first electronic device that displays a first shared interface, and sends interface data of the first shared interface to a second electronic device. The second electronic device receives the interface data, and displays a second shared interface corresponding to the first shared interface. The second electronic device enables an interconnection mode for the first electronic device, and when detecting a trigger operation performed by a user on the second shared interface, determines event information corresponding to the trigger operation. The event information includes an event type and operation area information that correspond to the trigger operation. The second electronic device sends the event information to the first electronic device. The first electronic device receives the event information, and performs a corresponding operation based on the event information.
